1N5333B Description

Short technical summary and product information.

The 1N5333B is a Zener diode from the 1N53xxB series of ON Semiconductor, offering a nominal Zener voltage of 3.3V with a tolerance of ±5%. It is designed for a maximum power dissipation of 5W at a lead temperature of 75°C, making it suitable for voltage regulation and protection applications. The device features a low Zener impedance of 3Ω at 380mA and a maximum Zener current of 1440mA.

 

This Zener diode is housed in a DO-15 molded plastic case with axial leads, allowing for through-hole mounting. It operates over a wide junction temperature range of -65°C to 200°C and has a thermal resistance of 45°C/W from junction to ambient. The lead is solderable per MIL-STD-202, method 208, and the cathode is identified by a color band.

 

With its high reliability, low leakage current of 300µA at 1V reverse voltage, and a forward voltage of 1.2V maximum at 1A, the 1N5333B is a robust choice for demanding environments.
