1N4100 Description

Short technical summary and product information.

The 1N4100 is a 500 mW Zener voltage regulator diode from Microchip Technology, part of the 1N4099-1 through 1N4135-1 series. It is housed in an axial-leaded DO-35 (DO-204AH) glass package and designed for through-hole mounting.

 

Key electrical specifications include a power dissipation of 500 mW at 25°C, derated linearly to 0 W at 175°C. The junction temperature range spans -65°C to 175°C. Thermal resistance is 300°C/W junction-to-ambient when mounted on FR4 with 4 mm² copper pads, and 250°C/W junction-to-lead at 10 mm lead length. Forward voltage is 1.1 V at 200 mA.

 

This diode is suitable for voltage regulation in a variety of circuits. The DO-35 package allows for flexible axial-lead mounting. The device is constructed with an internal metallurgical bond and is available in military-qualified levels per MIL-PRF-19500/435.
