For a 24 VDC input rail, a unidirectional TVS like the 1.5SMCJ7.5C clamps the positive transients — the C suffix marks unidirectional polarity, not bidirectional — protecting downstream MOSFETs and regulators from voltage spikes that exceed the rail rating. The 14.3 V clamping ceiling sits safely below the gate-drive thresholds of most 30 V-rated MOSFETs used in synchronous buck converters. ## DO-214AB SMC — the footprint that travels across families The DO-214AB (SMC) package is the de facto standard for 1500 W unidirectional TVS diodes across multiple brands. The cathode bar on the package body identifies the polarity end — pin-compatible substitutes from other manufacturers sharing the same SMC footprint are common, which matters when a last-time-buy or shortage forces a cross-sourced swap.","metaTitle":"1.5SMCJ7.5C TVS Diode, 1.5kW, 7.5V Standoff","metaDescription":"Diotec 1.5SMCJ7.5C unidirectional TVS zener, 1500W peak pulse, 7.5V standoff, 8.3V breakdown, DO-214AB SMC.
