Active production, 1500 W peak pulse in a DO-214AB
The SMCJ54A-13-F: Housed in the DO-214AB (SMC) surface-mount package, it is suited for general-purpose overvoltage protection on power rails, signal lines, and DC buses where a single unidirectional channel is needed.
Clamping voltage and operating temperature range
With a 54 V reverse standoff (working voltage) and a 60 V minimum breakdown voltage, the device triggers at 60 V and clamps transients to 87.1 V maximum — a 33 V clamp window that keeps downstream components within their voltage rating during a surge. Rated for continuous junction temperatures from -55°C to 150°C, the SMCJ54A-13-F can handle hot environments like engine bays or industrial enclosures without derating the peak pulse power at elevated ambient.
