It targets higher-voltage buses: 48V telecom, 72V industrial, or 90V nominal supplies where the transient needs a hard clamp at 178.8V. ## Package and temperature — the SQ-MELF and 175°C junction The SQ-MELF (B case) is a surface-mount package with a cylindrical body that handles high surge currents without cracking the solder joint — common in MIL-spec and high-reliability designs. The junction temperature range spans -55°C to 175°C, so it survives avionics cold-soak and engine-bay heat without derating the 500W pulse at the top end. ## Active production — no end-of-life watch needed Microchip lists the 1N6133US as Active. The base product number is 1N6133, and the US suffix denotes the SQ-MELF package variant.","metaTitle":"1N6133US Zener TVS Diode – 500W, SQ-MELF, Active – Microchip","metaDescription":"1N6133US Zener TVS diode from Microchip Technology. 500W peak pulse power, 98.8V standoff, 178.8V clamp, bidirectional.

A 24V rail would see no clamping action until the transient reaches nearly 100V — the downstream components would already be damaged. For 24V protection, look for a TVS with a standoff around 24-30V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6133US","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6133US when reusing this data.
