Transient Voltage Suppressors (TVS) are electrical components that are designed to protect delicate electronics from voltage surges or spikes. The SMA5J30HE3/61 is a surface mounted TVS diode specifically designed to provide protection from voltage transients in high bandwith applications such as digital camera systems, smart home devices, and medical technology.

When connected to a circuit, the SMA5J30HE3/61 absorbs excess voltage over a specific threshold, and can be used to protect power supplies, data lines, and electronic equipment from damage caused by spikes in a current or voltage. It is designed to quickly reduce the amount of voltage detected over the surge threshold, limiting the overall damage sustained and reducing the chances of electrical fires.

The SMA5J30HE3/61 is a bidirectional transient voltage suppressor that features a 5.3V unidirectional and 6.1V bidirectional breakdown voltage and an 8A peak pulse power. Its compact dual-ended SMT package measures only 2 x 3mm, making it suitable for applications where space is at a premium. The TVS is also designed to withstand high-temperature soldering, easily handling reflow soldering temperatures up to +260°C when needed.

The working principle behind the SMA5J30HE3/61 is quite simple. When paired with an electrical circuit, the component allows the flow of electricity as normal until a threshold voltage is reached. The device then triggers an avalanche breakdown, connecting the anode and cathode diodes and limiting the amount of voltage passing through the circuit. The reduced voltage is then balanced against the user-defined threshold, and the device disengages until the threshold is reached again.

The SMA5J30HE3/61 can be used in a wide range of applications. Its bidirectional protection capabilities make it an ideal choice for LCD controllers, rechargeable batteries, and digital camera systems, where power surges can easily cause damage. Due to its relatively small design, the device is also suitable for LTE/WCDMA/TD-SCDMA power supplies and satellite receivers, among other applications in a variety of industries.

The SMA5J30HE3/61 protects vulnerable electronics from power surges by quickly limiting any voltage spikes that exceed the user-defined threshold. The device is designed to guarantee a maximum breakdown voltage of 5.3V in one direction, and 6.1V in the other. Its fast-acting safeguard helps protect equipment from thermal damage, fires, and component failure, and its small size and high-temperature resistance make it suitable for a wide range of applications.
