1N5228B Description

Short technical summary and product information.

The 1N5228B is a 3.9V Zener diode from On Semiconductor, part of the 1N5221B-1N5252B series. It offers a nominal Zener voltage of 3.9V with a tolerance of ±5%, and a voltage range of 3.705V to 4.095V. The device is rated for 500mW power dissipation and operates over a junction temperature range of -65°C to 200°C.

 

This Zener diode features a maximum Zener impedance of 23Ω at 20mA test current and 1900Ω at 0.25mA knee current. The reverse leakage current is 10µA at 1V reverse voltage. The forward voltage is 1.2V at 200mA forward test current. The temperature coefficient is -0.060%/°C.

 

The 1N5228B is housed in a DO-204AH (DO-35) axial-lead through-hole package. It is suitable for general-purpose voltage regulation, voltage reference, and protection circuits in low-power applications.
