Transient voltage suppression (TVS) diodes are designed to protect sensitive circuitry from damage due to excessive electrical transients induced externally or generated internally. The SA160AHR0G is a unidirectional, 600W (10/1000μs) ultra low capacitance diode that is handy for protecting voltage boundaries and relays from fast energizing or heavy inrush current even in microsecond time domain. It provides high inrush current handling capabilities while minimizing voltage clamping levels and works against the voltage spikes, malfunction, surges and inductive switching transients.

The application fields of SA160AHR0G is widely embraced in numerous industries and fields. Electronics engineers often use it in combination with a range of electrical components such as active protection circuits and varistors in order to limit the potential damages of over-voltage, transients, static discharges, or low-level parasitic currents. It can be found being used for surge and over-voltage protection in consumer household appliances, industrial motor control systems, electronic measuring instruments, automotive systems, data communication networks, microprocessor-based equipment, consumer AV systems, etc. Additionally, SA160AHR0G comes in SMA, SMB, SMC, DO-220 package and is easy to install throughout various system designs.

The working principle behind SA160AHR0G is quite simple. It consists of a diode connected in reverse bias. The reverse bias causes the diode to be in a non-conducting state and thus no outside current is allowed to flow through it from the external source. However, when a transient voltage spike occurs the diode will be activated and become conductive due to the increased voltage. The diode then quickly diverts the excess current away from the affected circuit thus protecting all connected components from damage.

The term “ultra low capacitance” which is often associated with SA160AHR0G is due to its capacity to reduce transients with very minimal voltage differences. This feature is made possible due to the advanced technologies used in its construction which includes the utilization of thin-film diode that acts as an buffer to reduce voltage operation. The design of the SA160AHR0G also includes interpoles within its body to provide remarkable inductor performance in the microsecond domain.

The overall design and performance of the SA160AHR0G makes it an ideal device for protecting a wide array of devices and electronic components against hazardous transients and voltage spikes. It is more reliable than other conventional diodes and varistors types due to its advanced design and low capacitance which allows for quick respond mechanism in the microsecond domain.
