The SMC30J40A is a unidirectional Zener-type TVS diode designed for general-purpose transient voltage suppression. It offers a peak pulse power dissipation of 3000W (10/1000µs waveform) and a clamping voltage of 64.5V at a peak pulse current of 43.5A. The device has a reverse standoff voltage of 40V and a minimum breakdown voltage of 44.4V, providing reliable overvoltage protection for sensitive electronics.
This component does not include power line protection and is intended for single-channel unidirectional applications. The operating junction temperature range spans from -55°C to +175°C, allowing use in demanding thermal environments.
The SMC30J40A is housed in a standard DO-214AB (SMC) package and supports surface mount assembly. The supplier device package is SMC, facilitating automated pick-and-place manufacturing.
