TPD2E001DRLR Description

The TPD2E001 is a two-channel electrostatic discharge (ESD) protection diode array based on transient voltage suppressors (TVS). The international standard IEC 61000-4-2, Level 4, rates TPD2E001 for the maximum electrostatic discharge (ESD) strikes allowed. A non-magnetic DRS package (3.00 mm x 3.00 mm) is also offered in medical imaging applications.

In-depth Description

Electrostatic discharge (ESD) protection diode array with two-channel transient voltage suppressor (TVS) circuit, model number TPD2E001. The TPD2E001 was proven capable of dispersing the charge when exposed to electrostatic discharge (ESD) strikes at the highest level allowed by international standard IEC 61000-4-2 Level 4.

The TPD2E001 is an electrostatic discharge (ESD) protection device with a low capacitance and only one direction of protection, according to the feature description. The device’s design incorporates a central ESD clamp with two concealing diodes for each line to reduce capacitive loading. This center ESD clamp, which is also connected to the VCC line, shields it. Each IO line is rated to dissipate electrostatic discharge (ESD) strikes at a level greater than the upper limit specified in the international standard IEC 61000-4-2 level 4. The TPD2E001 is a superb option for safeguarding high-speed signal connections due to its incredibly low loading capacitance.

Functional Modes for Devices

When voltages higher than VBR or lower than the lower diodes Vforward are present on the protected circuit, the passive integrated circuit TPD2E001 becomes active (–0.6V). The internal diode network can route up to 15 kV voltages to either ground or VCC during electrostatic discharge (ESD) accidents. The device will switch back to its high-impedance mode when the protected lines’ voltages fall below the trigger voltage of the TPD2E001. Usually, this takes place in a few tens of nanoseconds.

Application Details

TPD2E001 is a transient voltage suppressor in the form of a diode array (TVS). Its main job is to give electrostatic discharge (ESD) incidents on high-speed communication lines between a human interface connector and a system a way to ground. Diode voltage is somewhat reduced by the ESD current flowing over the TVS. This is the voltage that is supplied to the protected integrated circuit. Due to the low RDYN of the activated TVS, this voltage, VCLAMP, is kept at a suitable level for the protected integrated circuit.

Recommendations for Power Supplies

This ESD protection device is passive; thus, electricity is not required to keep it from preventing electrostatic discharge. The maximum voltage parameters for each line must not be exceeded in any way; thus, caution must be exercised in this area.

Structure Layout Rules

The best approach is to place something as close to the connector as possible.

  • Electromagnetic interference (EMI) during an ESD event can spread from the trace being struck to nearby traces that are not insulated, which can cause early system failures.
  • By ensuring that any exposed traces are kept a safe distance away from protected traces situated between the TVS and the connection, the printed circuit board (PCB) designer can lessen the possibility of electromagnetic interference (EMI) coupling.
  • For the shielded traces, keep as much of the trail straight as you can.
  • You can prevent sharp edges from forming between the TVS and the connector by giving the shielded traces’ corners the largest practicable radii and smoothing them off as much as possible.
  • Electric fields have a propensity to accumulate on corners, increasing EMI coupling.

What is a Transient Voltage Suppressor (TVS) diode?

Avalanche diodes are known as “transient voltage suppressors,” or TVS for short. This diode was created to suppress high transient power surges and clamp overvoltages. High current surges can be momentarily diverted using protection devices made by ST under the TransilTM name.

To ensure protection from electrical overstress (EOS) or electrostatic discharges, solid-state, monolithic PN junction devices and transient voltage suppressors are used alongside sensitive semiconductors in a parallel protection system (ESD).

Because there are no aging effects, TVS devices have various advantages over metal-oxide varistors (MOV). This ensures that the device will remain stable over time, improving reliability. There are numerous other benefits to TVS devices.

Zener solutions are not preferred over TVS designs because of their lower quality and fragility. Zener solutions are not specified for surges and have a low DC rating. TVS designs are more durable and of greater quality.

Performance-oriented TVS gadgets

AEC-Q101-compliant high-performance devices of industrial and automotive grade are available in the ST TVS product portfolio. This makes it easier to guarantee complete adherence to all relevant regulatory requirements and industry standards.

The maximum power density on the market is provided by our most recent generation of TVS diodes. These diodes are made for a range of industrial and automotive applications.
