DSP25-12A Introduction

A diode array, the DSP25-12A, consists of 1 pair of series-connected diodes that can tolerate voltages up to 1200V and currents up to 28A. It is appropriate for high-power applications where heat dissipation is a concern because it is available in a through-hole TO-247-3 packaging.

Electronic circuits require the use of diode arrays because they have a number of advantages over individual diodes. They offer increased current and voltage capabilities, better heat dissipation, less need for board space, and improved dependability. They frequently appear in circuits for power supplies, motor controls, and high-frequency rectification. It is impossible to overestimate the significance of diode arrays in electronic circuits because they are essential to the proper operation of many different electronic systems and devices.

DSP25-12A Technical specifications

With a maximum voltage rating of 1200 V and a maximum current rating of 28 A, the DSP25-12A diode array comprises one pair of diodes connected in series. It can deliver dependable and effective rectification and freewheeling in high-voltage applications, including power supplies and motor drives.

The through-hole TO-247-3 packaging, a popular package type for high-power electronics, is what the DSP25-12A is packaged in. The device has three leads; the central lead serves as the collector for the two diodes, while the outer leads serve as the emitters. It can be used in a number of applications due to the package’s dimensions of 15.75 mm x 5.32 mm x 20.57 mm.

When the forward current is 25 A, the diode’s forward voltage drop in the DSP25-12A is 1.7 V, which is comparatively low compared to other high-power diodes. As a result of the diodes’ ability to switch rapidly and effectively—with a reverse recovery time of only 160 ns—switching losses are kept to a minimum, and overall efficiency is increased.

The DSP25-12A has a maximum junction temperature of 175 °C; if used over this temperature, the device may malfunction. Additionally, the device has a thermal resistance of 0.55°C/W, which shows how well it can dissipate heat. In high-power applications where heat dissipation is vital, a reduced thermal resistance means that the device can dissipate heat more effectively.

All things considered, the DSP25-12A is a highly effective and dependable diode array that may be applied in a range of high-voltage applications. Its high switching speed and low forward voltage drop make it an effective option for power conversion. In contrast, it’s TO-247-3 packaging and thermal parameters make it appropriate for usage in challenging conditions.

DSP25-12A Applications

Circuits for rectification: The DSP25-12A can be used in circuits for AC to DC converters, where it rectifies signals. By enabling the current to only travel in one direction, it helps to convert the AC voltage to DC voltage.

Freewheeling circuits: The DSP25-12A can function as a freewheeling diode in inductive loads. In the event that the main switch is switched off, it offers a low-impedance channel for the current to flow. By doing this, you can prevent voltage spikes from damaging the switch and other parts.

Circuit snubbers: The DSP25-12A can be used in circuit snubbers to reduce voltage transients that happen in switching circuits. It aids in shielding the switch and other components from overvoltage stress.

Advantages of using a diode array over individual diodes

  • Diode arrays integrate several diodes into a single package, which frees up space on a circuit board.
  • Diode arrays are frequently more affordable than purchasing individual diodes for each application.
  • Increased reliability: Because the diodes are combined into a single package, there is a reduced risk that they may be harmed during handling or installation.

DSP25-12A Design considerations

The DSP25-12A’s critical parameters, including peak inverse voltage, average forward current, and surge current rating, should be considered while incorporating a circuit. If these characteristics are considered, the diode array will be more appropriately rated for the intended application.

Utilizing a diode array like the DSP25-12A can simplify circuit design and reduce the number of components needed, which is a significant benefit. Limiting parasitic effects can conserve space, cut expenses, and boost overall performance.

However, there are disadvantages to using a diode array rather than a single diode. For instance, employing individual diodes, which can be chosen based on particular application requirements, might be more flexible than the DSP25-12A. Additionally, whereas individual diodes can be replaced separately if one diode in the array fails, the entire array must be replaced.

In general, designers should carefully analyze their unique application needs and weigh the advantages and trade-offs of employing a diode array vs an individual diode when selecting whether to utilize a diode array like the DSP25-12A.

Comparison to Similar Products

A number of other diode arrays are available on the market, but the DSP25-12A is a diode array made for high-voltage and high-current applications. The IXYS DSEP15-06A is a comparable product with a peak reverse voltage of 1200V and a current rating of 28A. The DSP25-12A has a forward voltage drop of 1.4V, whereas the DSEP15-06A has a larger forward voltage drop of 1.9V. As a result, the DSP25-12A operates more effectively and produces less heat, which might be significant in applications where heat dissipation is a problem.

The Infineon FF600R12ME4 is a different diode array that competes with the DSP25-12A. This model has a similar 28A current rating and a greater peak reverse voltage of 1200V, but a higher forward voltage drop of 1.6V. The Infineon product also has various electrical and thermal characteristics and a different package type. Circuit designers must, therefore, carefully analyze their application’s unique needs while selecting between these components.

Overall, the DSP25-12A is an excellent option for high-power applications. Limiting heat generation is vital due to its efficiency and low forward voltage drop, which sets it apart from other diode arrays. Additionally, considering how inexpensive it is compared to comparable products, it is a desirable choice for applications with a tight budget.


In conclusion, the high-performance DSP25-12A diode array offers exceptional rectification, freewheeling, and snubber circuit performance. It is excellent for high-power applications due to its highest voltage and current ratings, minimal forward voltage loss, and quick reverse recovery time. Additionally, it is simple to use in various designs due to its small TO-247-3 package and low thermal resistance.
