The 500W rating means it can absorb a decent surge — think inductive kickback from a relay coil or a short ESD hit on a 5V rail. ## 500W peak pulse — what that buys you The 500W peak pulse power is the headline number. For a 5V rail, that translates to a 56A peak pulse current capability — enough to handle moderate surges in industrial control or automotive auxiliary circuits. No power line protection (no internal TVS array for AC mains), so this is strictly for DC rail or signal-line clamping where the transient energy stays within the 500W envelope. ## Active production — sourcing posture The SQ-MELF B package is a standard footprint, and tape-and-reel delivery suits automated pick-and-place. ## Package and temperature grade SQ-MELF B (surface-mount) package — cylindrical body with solderable end caps. The -55°C to 175°C junction operating range covers most harsh environments: underhood automotive, outdoor telecom cabinets, industrial sensor nodes. The wide temp range also means the leakage and clamping behaviour stay predictable across the full span.","metaTitle":"1N6461US/TR – Microchip Zener, 500W, SQ-MELF, Active","metaDescription":"Microchip 1N6461US/TR Zener diode, 500W peak pulse, 5V standoff, SQ-MELF B package.
