1N4370A Description

Short technical summary and product information.

The 1N4370A is a 2.4V Zener diode from ON Semiconductor designed for general-purpose voltage regulation and clamping applications. It features a nominal zener voltage of 2.4V at 20mA with a tolerance of ±5%. The device can dissipate up to 500mW of power at lead temperatures up to 75°C, with a derating factor of 4.0mW/°C above that point.

 

Electrical characteristics include a maximum forward voltage of 1.5V at 200mA, reverse leakage current of 100µA at 1V, and a zener impedance of 30Ω at 20mA. The maximum zener current is 150mA at 25°C ambient. The diode operates over a wide temperature range from -65°C to 200°C.

 

The 1N4370A is housed in a DO-35 (DO-204AH) glass package with axial leads for through-hole mounting. The cathode is identified by a color band. This part is part of the 1N4370A-1N4372A and 1N746A-1N759A series of zener diodes covering voltages from 2.4V to 12V.
