Its single bidirectional channel protects lines that see both positive and negative transients — useful on AC signal pairs or bipolar DC rails where unidirectional parts would need anti-parallel stacking. ## Temperature range and breakdown margin Minimum breakdown is 104.5 V, with a reverse standoff of 86.6 V — the gap between standoff and breakdown sets the leakage floor under steady-state bias; the 151.3 V clamp ceiling limits the voltage the protected circuit sees during a surge. Microchip lists the 1N6167US as Active.","metaTitle":"1N6167US Zener TVS Diode – 1500W Bidirectional, SQ-MELF","metaDescription":"Microchip Technology 1N6167US Zener TVS: 1500W peak pulse power, bidirectional, 86.6V standoff, SQ-MELF surface mount.
