The through-hole axial package (B, Axial case) is a legacy footprint that survives high-energy pulses better than surface-mount alternatives — the leaded body sinks heat into the board copper. ## Peak pulse power and clamping performance At 1500W peak pulse power, the 1N6144A clamps a 88.8A surge to 16.9V max — that is a 1.9× voltage margin above the 9.1V standoff, typical for a Zener TVS. The bidirectional channel handles both positive and negative transients in one device, saving board space on AC-coupled or bipolar signal lines. ## Active lifecycle and sourcing posture The through-hole axial package is a standard production item, so lead times track the broader Microchip TVS portfolio. For current pricing and availability, submit an RFQ; the part is sourced to order against your BOM quantity.","metaTitle":"1N6144A TVS Diode – 1500W Bidirectional Zener, Axial, Active","metaDescription":"1N6144A bidirectional Zener TVS diode from Microchip Technology. 1500W peak pulse power, 9.1V standoff, -55°C to 175°C.
