1N4371A Description

Short technical summary and product information.

The 1N4371A is a 2.7V Zener diode from ON Semiconductor, part of the 1N4370A-1N4372A series. It offers a nominal zener voltage of 2.7V with ±5% tolerance, tested at 20mA. The maximum zener impedance is 30Ω at the test current. Forward voltage is 1.5V maximum at 200mA forward current. Reverse leakage current is 75µA maximum at 25°C and 150µA maximum at 125°C, measured at 1V reverse voltage.

 

Power dissipation is rated at 500mW at lead temperatures up to 75°C, with a derating factor of 4.0mW/°C above 75°C. The maximum zener current is 135mA. The device operates over a temperature range of -65°C to 200°C.

 

The 1N4371A is housed in a DO-35 (DO-204AH) through-hole package with axial leads, suitable for manual or wave soldering. Typical applications include voltage regulation, overvoltage clamping, and voltage reference in low-power circuits.
