The SMC30J40CA is a bidirectional Zener TVS diode from STMicroelectronics designed for general purpose transient voltage suppression. It features a reverse stand-off voltage of 40V and a maximum clamping voltage of 64.5V at a peak pulse current of 43.5A. The device can handle 3000W (3kW) of peak pulse power, making it suitable for protecting sensitive electronics from voltage transients.
This TVS diode operates over a junction temperature range of -55°C to 175°C, ensuring reliable performance in harsh environments. It is not intended for power line protection, but is well-suited for signal and data line applications. The bidirectional configuration allows protection for circuits with both positive and negative voltage swings.
The component is surface mount packaged in a DO-214AB (SMC) case, which is compatible with standard reflow soldering processes. The SMC package offers a compact footprint while delivering high surge capability.
