SM8S30CA-Q Description

Short technical summary and product information.

The SM8S30CA-Q is a bidirectional Zener TVS diode from Bourns designed for high-power surge protection. It offers a working peak reverse voltage of 30V and a breakdown voltage range of 33.3V to 36.8V at 5mA test current. The clamping voltage is 48.4V at a peak pulse current of 136A (10/1000μs waveform). With a peak pulse power dissipation of 6600W (10/1000μs) and 5200W (10/10000μs), this device is suited for demanding surge environments. It also supports continuous power dissipation of 8W with an infinite heatsink at 25°C case temperature. The operating junction temperature range is -55°C to +175°C. The device is packaged in a surface-mount DO-218AB package, making it suitable for automated assembly. Applications include automotive electronics, high peak power clamping, load switching, and lighting protection modules. The device meets AEC-Q101 qualification and is RoHS3 compliant (unverified).
