The CPC1008NTR  is a small solid-state relay typically open (1-Form-A), single-pole, low-voltage, and low on-resistance. It is housed in a 4-Pin SOP box. It utilizes Clare’s unique OptoMOS architecture, which is optically connected, to offer input/output isolation of 1500Vrms. The CPC1008N is one of the world’s smallest relays. It achieves this status by utilizing Clare’s cutting-edge double-moulded vertical construction packaging. It is an excellent choice for replacing electromechanical relays and bigger reed relays, which are less dependable.

Frequently asked questions

What is a Solid-state relay?

When an external voltage, either alternating current or direct current, is delivered across the control terminals of an electrical switching device known as a solid state relay (SSR), the device can be turned on or off depending on which type of voltage is being applied. They perform the same task as an electromechanical relay. Still, because they are made of solid-state electronics, they do not have any moving parts and have a longer lifetime in operation.

SSRs are made up of a sensor that reacts to an appropriate input (control signal), an electronic switching device that switches power to the load circuitry, and a coupling mechanism that enables the control signal to activate this switch without the use of mechanical parts. Together, these three components make up an SSR. They can be built to switch either alternating current (AC) or direct current (DC) loads.

Power semiconductor components like thyristors and transistors are used in packaged SSRs to switch currents up to roughly 100 amperes. SSRs feature quick switching speeds compared to electromechanical relays, and they do not have any physical contacts that can become worn out over time.

In contrast to electromechanical relays, solid-state relays (SSRs) have a higher “on” resistance and cannot endure the same levels of temporary overload as their counterparts.

What’s The Process Of A Solid-State Relay?

In AC circuits, SCR or TRIAC relays automatically turn off at the locations of AC zero-cross whenever there is zero load current. This occurs when there is a complete absence of load current. Because the circuit won’t ever be broken in the middle of a sine wave peak, significant transient voltages won’t ever develop due to the quick collapse of the magnetic field around the inductance like they would if it did. This will prevent large voltage spikes from happening. The individual SCRs can be turned back on at the beginning of a new wave if a zero-point detector is included in the circuit. Additionally, there must not be any adverse circuit inductance or back-e.m.f. as a result. This function is known as zero-crossing switching, often called zero-crossover switching.

When it comes to DC loads, an SSR based on either a single MOSFET or numerous MOSFETs in a paralleled array can perform admirably. Because each MOSFET has a substrate diode that also conducts in the opposite direction, a single MOSFET can’t block current flowing simultaneously. MOSFETs are often wired in a back-to-back configuration for AC (bi-directional) operation, with their source pins connected. Both sides of the output are linked to the drain pins of these components. When the relay is turned off, the reverse bias is alternately applied to the substrate diodes, which block current. When the relay is activated, the common source will always be riding on the instantaneous signal level, and the photodiode will bias both gates to have a positive bias in relation to the source.

When switching a DC load, it is customary to offer access to a common source so that multiple MOSFETs can be linked in parallel. This is done to save space. When the control input is disconnected, a network is typically provided to hasten the turn-off of the MOSFET.

SSRs used for DC switching applications could make use of IGBTs or MOSFETs.

What causes SSR to fail?

The SSR output elements might be damaged if a high reverse voltage was present, created by inductive loads like valves and solenoids. Utilize the SSR with a component capable of absorbing the generated reverse voltage. An unexpected surge from the outside could cause harm to the input or output elements. In addition, a problem could be caused by a load short circuit.

Can SSR switch AC?

A solid-state relay (SSR) can be built to switch either a direct current (DC) load or an alternating current (AC) load, and some varieties can change both types of loads. The type of switching device used in an SSR—a transistor (either bipolar or MOS), an SCR, or a TRIAC—decides the output type—alternating current, direct current, or alternating current and direct current.

What is the difference between a relay and a solid-state relay?

The absence of moving connections in solid-state relays is the primary distinction between them and traditional relays. General relays have movable contacts (SSR). SSRs can perform high-speed and high-frequency switching operations. Solid-state relays are generally comparable to mechanical relays with moveable contacts.

Where are solid-state relays used?

The switching of an AC load is the most common application for solid-state relays. This could be to control the AC power for ON/OFF switching, light dimming, motor speed control, or other applications requiring power control. These AC loads can be easily controlled with a low current DC voltage.
