The SQ-MELF C package is a surface-mount ceramic body with solderable end caps, suited for automated pick-and-place and reflow assembly. The -55°C to 175°C junction temperature range supports deployment in avionics, industrial controls, and outdoor telecom where ambient extremes are routine. ## Clamping voltage and pulse current Breakdown occurs at a minimum of 7.13V, ensuring the device triggers before the protected circuitry sees damaging overvoltage. At the rated 133.9A peak pulse current, the clamp voltage holds at 11.2V max — a tight ratio that limits stress on downstream semiconductors. Bidirectional operation (single channel) means the same device protects both positive and negative transients, simplifying BOM count on AC-coupled or bipolar signal lines. ## Active production status Microchip continues to manufacture this part, so the supply channel is open for both prototype and production quantities. The base product number is 1N6139; the AUS suffix denotes the surface-mount SQ-MELF variant. No direct replacement or successor has been announced — this is the current ordering code for the bidirectional, 1500W, SQ-MELF configuration.","metaTitle":"1N6139AUS Zener TVS Diode – 1500W, SQ-MELF, Microchip","metaDescription":"1N6139AUS from Microchip Technology – Zener TVS, 1500W peak pulse, 5.7V reverse standoff, bidirectional, SQ-MELF surface mount.
