The Bourns SMCJ30CA-Q is a 1500W bidirectional transient voltage suppressor (TVS) diode from the SMCJ-Q series, designed for overvoltage protection in automotive and other demanding applications. It features a Zener type structure with a maximum clamping voltage of 48.4V at a peak pulse current of 31A (10/1000 μs waveform). The device provides a minimum peak pulse power dissipation of 1500W and an ultra-fast response time of less than 1.0 picosecond from 0V to breakdown voltage.
This TVS diode is qualified to AEC-Q101 for automotive reliability and is RoHS compliant. It is UL recognized under file number E153537. The operating junction temperature range spans -55°C to 150°C, making it suitable for harsh environments. The part is also characterized for a peak forward surge current of 200A (8.3 ms single half sine wave).
The SMCJ30CA-Q is housed in a surface-mount DO-214AB (SMC) package, which is JEDEC standard and compatible with automated pick-and-place equipment. The flat configuration minimizes roll-away during assembly. Typical applications include protection of power buses, I/O interfaces, and overvoltage transient protection in automotive comfort, entertainment, telecom, industrial, and consumer electronics.
