Transient suppressor for 40V rails
The 1N6055A is a bidirectional Zener TVS diode from Microchip Technology, designed to clamp transients on a 40V nominal rail. It delivers 1500W peak pulse power per the 10/1000µs waveform, with a breakdown voltage minimum of 44.7V and a clamping ceiling of 64.8V at 23.2A peak pulse current. The DO-13 through-hole package suits point-of-use board-level protection where a soldered leaded device is preferred over surface-mount for thermal mass and mechanical retention.
Thermal and surge margins
Operating junction temperature range spans -55°C to 175°C, which covers underhood automotive, industrial motor drives, and outdoor telecom enclosures without derating concerns at the hot end. The 23.2A peak pulse current rating at 10/1000µs defines the surge-handling capacity — a 40V rail hit with a lightning-induced transient or inductive load dump stays clamped below 65V.
Production status and package availability
the DO-13 package is a standard through-hole format compatible with wave-solder and hand-solder assembly lines.
