The 136.8 V standoff rating means the diode does not conduct at normal operating voltages up to that level, so it sits across the rail without leakage penalty. The 1500 W peak pulse power rating is the energy-handling ceiling for a single 10/1000 µs pulse — derate for repetitive events or higher ambient temperatures. ## Active production, through-hole axial package The part ships in the B, Axial package — a through-hole form factor suited for point-to-point wiring, terminal blocks, or PCB mounting where the axial leads are bent and soldered.","metaTitle":"1N6172A Zener TVS Diode - 1500W, Axial, Microchip","metaDescription":"1N6172A Zener TVS diode from Microchip Technology. 1500W peak pulse power, 136.8V standoff, 245.7V clamp.
