Its 17.1V minimum breakdown voltage and 13.7V reverse standoff make it a fit for clamping transients on 12V nominal DC rails — the standoff sits above the rail's normal maximum, so the diode stays out of conduction during steady-state operation. This is a single bidirectional channel, meaning it clamps both positive and negative surges without needing an anti-series pair. The 59.8A peak pulse current (Ipp) at the 25.1V clamping limit gives the surge margin for industrial and telecom line-side protection. ## Through-hole B, Axial – rework and board fit The B, Axial package is a through-hole leaded form — the body is cylindrical with wire leads exiting each end. It solders into a plated through-hole on the board and can be replaced with a standard soldering iron or a hot-air station set for leaded components; the thermal mass is low enough that a hand-solder swap is routine. Orientation is unambiguous — the cathode band marks the polarity for the unidirectional variant, though this bidirectional channel has no polarity mark. The 175°C TJ(max) means the diode can absorb repetitive surge energy in a hot environment — useful in engine-bay or industrial oven-adjacent placements.","metaTitle":"1N6148A/TR Zener TVS Diode – 1.5 kW, 17.1 V Breakdown, Axial","metaDescription":"Microchip 1N6148A/TR Zener TVS diode: 1.5 kW peak pulse, 17.1 V breakdown, 13.7 V standoff, 59.8 A Ipp. Active production, through-hole B, Axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"B, Axial","Product Status":"Active","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":"B, Axial","Voltage - Breakdown (Min)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.1V","Voltage - Reverse Standoff (Typ)":"13.7V","Current - Peak Pulse (10/1000µs)":"59.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.1101","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 the 1N6148A/TR bidirectional?","answer":"Yes, it is a single bidirectional channel.
