The reverse standoff voltage of 28.2 V means the diode stays high-impedance below that level, so a 24 V rail sees no leakage penalty during normal operation. Breakdown occurs at 31.4 V minimum, giving a 3.2 V guard band before the TVS starts conducting. ## Bidirectional channel — one part for both polarities A single bidirectional channel protects against positive and negative transients on the same line. For AC signal lines or bipolar DC rails, this eliminates the need for two back-to-back unidirectional diodes and simplifies the PCB layout.","metaTitle":"1.5SMC33CA Littelfuse TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5SMC33CA bidirectional TVS diode, 1500W peak pulse power, 28.2V standoff, 45.7V clamping.
