The bidirectional structure handles AC or bipolar lines without back-to-back series diodes. ## Hermetic SQ-MELF package for harsh environments This part comes in a SQ-MELF B package (surface-mount, hermetic ceramic). The operating temperature range spans -55°C to 175°C, suiting avionics, downhole, or under-hood automotive applications where standard plastic packages degrade. The hermetic seal resists moisture and thermal cycling — a reliability advantage over non-hermetic alternatives. ## Active production — sourcing via RFQ It is supplied in Tape & Reel (TR) for automated assembly. For current pricing and lead time, submit an RFQ against your BOM quantity.","metaTitle":"1N6126AUS/TR Zener TVS Diode – 64.6V Breakdown, 500W","metaDescription":"Microchip 1N6126AUS/TR bidirectional Zener TVS, 64.6V min breakdown, 500W peak pulse, SQ-MELF B surface mount.
