Active production — no lifecycle risk
The 1N6476: For BOM planning this means no last-time-buy clock is ticking, and the part can be ordered against recurring builds without qualification of a replacement.
1500W peak pulse — clamping voltage at 78.5V
The reverse standoff voltage is 51.6V, so the diode stays out of conduction below that rail level — a 48V nominal bus with 15% tolerance sits safely under the standoff.
Single-channel Zener, axial through-hole
Unidirectional single-channel Zener in a G axial package — the same body as the classic DO-13 outline. Through-hole mounting suits point-to-point wiring, terminal blocks, or high-reliability socketed assemblies where a surface-mount TVS would be mechanically fragile.
Rated for continuous junction operation from -55°C to 175°C. That 175°C ceiling is unusual for a plastic axial package — it allows the diode to share a hot chassis or sit near a power resistor without derating the surge capability.
