Junction temperature rated to 175 °C — this gives thermal headroom for transient events where the clamping action dumps energy into the body; the -55 °C cold start means it survives cold-plate or outdoor-equipment deployments without a warm-up transient window.","metaTitle":"Vishay 1N6268-E3/54 TVS Diode, 11.7V Clamp, DO-201AA","metaDescription":"Vishay 1N6268-E3/54 unidirectional TVS diode, 11.7V clamping, 1500W peak pulse.
