It is rated for a reverse standoff voltage of 7.6 V and clamps at 14.5 V when hit with a 103.4 A, 10/1000 µs surge waveform. The -55°C to 175°C junction temperature range suits it for avionics, downhole drilling, and under-hood automotive environments where the ambient can push past 125°C. The 14.5 V clamping voltage at 103.4 A (10/1000 µs) tells you the maximum voltage the downstream circuit sees during the surge. If your 7.6 V rail has a 15 V absolute-maximum input rating on the regulator, this clamp provides a 0.5 V margin — tight but workable. The 1500 W peak-pulse rating assumes the junction starts at 25°C; at 175°C the derating curve in the datasheet reduces that capability, so thermal derating is required for continuous high-temperature operation. ## Bidirectional — one part for both polarities With a single bidirectional channel, the 1N6142A clamps equally on positive and negative transients. That saves a diode and a PCB via on AC-coupled signal lines, RS-485 pairs, or bipolar power rails where the return path sees the same surge energy. The symmetrical breakdown characteristic also eliminates the need to orient the part on the board — a time-saver for rework and assembly. ## Active production — no end-of-life watch needed Microchip lists the 1N6142A as Active. The axial-lead package (B, Axial) is a through-hole form factor that mates with standard 0.100-inch pitch prototyping boards and terminal blocks — no special footprint or stencil required.","metaTitle":"1N6142A Zener TVS Diode – 1500W, 7.6V Standoff","metaDescription":"Microchip Technology 1N6142A Zener TVS diode: 1500W peak pulse power, 7.6V reverse standoff, 14.5V clamping at 103.4A, bidirectional, -55°C to 175°C, Active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"B, Axial","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Voltage - Breakdown (Min)":"9.5V","Voltage - Clamping (Max) @ Ipp":"14.5V","Voltage - Reverse Standoff (Typ)":"7.6V","Current - Peak Pulse (10/1000µs)":"103.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.microsemi.com/document-portal/doc_download/127853-1n6138-1n6173a-tvs-diode-series-datasheet","sourceUrl":null},"ai":{"faq":[{"question":"Is 1N6142A unidirectional or bidirectional?","answer":"It is a single bidirectional channel.
