SA70AHB0G Circuit Protection

Transient voltage suppressors (TVSs), also known as transorbs or surge stoppers, protect sensitive electronic components from damage caused by electrostatic discharge (ESD) and transient voltage events. SA70AHB0G is a TVS diode from Semtech Corporation. It is designed to protect equipment and wires against the transact voltage and electrical overstress (EOS).

1. SA70AHB0G application field

SA70AHB0G is a multilayer technology, radial leaded, fast acting diode. Its cylindrical package and thin radial-Anode lead provides an integrated ESD/EOS gate protection. It is ideal for portable device, adapter, charger, LCD-TV, multimedia system, digitalizing products and etc. SA70AHB0G also provides a high surge peak current capability with low surge response times, making it suitable for wider range of application. The high robustness of this product makes it ideal for consumer and automotive application.

2. SA70AHB0G working principle

The working principle of SA70AHB0G is relatively straightforward. It is actually a unidirectional, voltage clamping device that is designed to protect against transient voltage line. The TVS diode will absorb and clamp the destructive transient voltage to a safe level, thus protecting electronic equipment from excessive voltage levels. This is done by a series of small junctions on the TVS diode that breakdown when the voltage passed through them exceed their specified threshold. When the breakdown occurs, the TVS diode then dissipates the surplus current away from the protected circuit. In this way, it can ensure the safety of the protected circuit.

3. Conclusion

SA70AHB0G is a multi-layer, radial leaded, fast acting diode from Semtech Corporation. It is designed to protect sensitive electronic components from damage caused by ESD and transient voltage events. Its cylindrical package and thin radial-Anode lead provides integrated gate protection and suitable for consumer and automotive applications. The working principle of SA70AHB0G is relatively straightforward and it is also an unidirectional, voltage clamping device which dissipate the surplus current away from the protected circuit when the breakdown occurs.
