The STMicroelectronics SMC50J85A is a unidirectional Zener-type TVS diode designed for general-purpose transient voltage suppression. It offers a peak pulse power dissipation of 5000 W (5 kW) and can handle a peak pulse current of 32 A. The device has a reverse standoff voltage of 85 V and a clamping voltage of 137 V.
This TVS diode is housed in a surface-mount DO-214AB (SMC) package, making it suitable for automated assembly processes. It operates over a junction temperature range of -55°C to 175°C, providing robust performance in demanding environments. The single unidirectional channel is ideal for protecting sensitive electronics on positive voltage rails.
The SMC50J85A is RoHS3 compliant and has an MSL of 1 (unlimited floor life), simplifying handling during manufacturing. It is commonly used in power supplies, industrial equipment, and telecommunications systems where high-power transient protection is required.
