1N4112DUR-1 Description

Short technical summary and product information.

The 1N4112DUR-1 is a 500mW Zener voltage regulator diode from Microchip Technology (formerly Microsemi), part of the 1N4099UR-1 to 1N4135UR-1 series. It is housed in a hermetically sealed glass DO-213AA surface mount package.

 

Key electrical specifications include a power dissipation of 500mW, Zener impedance of 100Ω, forward voltage of 1.1V at 200mA, and reverse leakage current of 50nA at 13.7V. The device offers a voltage tolerance of ±1% and operates over a junction temperature range of -65°C to 175°C.

 

Thermal characteristics include a junction-to-ambient thermal resistance of 300°C/W and junction-to-end cap thermal resistance of 100°C/W. The diode is suitable for high-reliability applications and is available in commercial and mil-qualified versions (JAN, JANTX, JANTXV, JANS). RoHS compliance is indicated for commercial grade, with MSL rating of 1 (unlimited).
