The clamping voltage is specified at 91.1V maximum at a peak pulse current of 18.5A (10/1000 µs waveform). That clamping ceiling defines the voltage stress the protected circuitry must survive during a surge event. Peak pulse power is rated at 1500W — a standard rating for this package size, giving a known energy-handling budget for transient suppression in a single unidirectional channel. Production is ongoing, and the part is available for order against BOM quantities.","metaTitle":"SMCJ51E3/TR13 – Microchip 1500W Zener TVS Diode, DO-214AB","metaDescription":"SMCJ51E3/TR13 Zener TVS diode from Microchip Technology. 51V standoff, 91.1V clamp, 1500W peak pulse.
