The SQ-MELF (B) package is a surface-mount ceramic barrel — the same footprint as a standard MELF diode but with a square body that improves solder-joint inspection and board-level handling. It mates to a standard SOD-123 or similar land pattern, so the board layout is straightforward. ## Temperature range and environment — where this part survives Rated for -55°C to 175°C junction temperature, the 1N6462US handles avionics cold-soak, engine-bay heat, and downhole tool temperatures without derating the 500W pulse capability. The ceramic SQ-MELF package also resists moisture absorption better than plastic SMD packages, so it stores well on the shelf without dry-bag concerns. ## Lifecycle and sourcing — active production, no last-time-buy pressure Microchip lists the 1N6462US as Active. The base product number is 1N6462, so the US suffix indicates the SQ-MELF package variant — the die and electrical specs are identical to the through-hole 1N6462, but the surface-mount form factor saves board space. Because it is active, we source it to order against your BOM quantity. Current pricing and lead time are confirmed at quote time — no stock-holding claim, but the supply channel is open.","metaTitle":"1N6462US TVS Diode – Microchip, 500W, 6V Standoff, SQ-MELF","metaDescription":"1N6462US Zener TVS diode from Microchip Technology. 500W peak pulse power, 6V reverse standoff, 11V clamping.
