That margin keeps downstream devices rated at 36V or higher safe — a 24V bus or 12V-to-24V converter output sees the clamp engage well before the silicon limit. The 1500W peak pulse power rating is measured with a 10/1000 µs exponential waveform — the standard telecom and industrial surge test. For shorter pulses (8/20 µs, common in ESD testing), the device can absorb significantly higher peak current, but the 10/1000 µs figure is the one to use for mains-coupled transient coordination. ## Active production — sourcing for the BOM The R7G suffix indicates Tape & Reel packaging for automated assembly.","metaTitle":"1.5SMC22CA R7G TVS Diode, 1.5kW Bidirectional, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC22CA R7G Zener TVS, 1500W peak pulse power, 30.6V clamping, bidirectional, DO-214AB SMC.
