1N5226B Description

Short technical summary and product information.

The 1N5226B is a 3.3V Zener diode from onsemi, part of the 1N5221B-1N5252B series. It offers a nominal Zener voltage of 3.3V with a ±5% tolerance, ensuring a regulation range of 3.135V to 3.465V. The device is rated for 500mW power dissipation at 25°C ambient, with derating above 50°C at 4.0 mW/°C. It operates over a junction temperature range of -65°C to 200°C.

 

Key electrical characteristics include a Zener impedance of 28Ω at 20mA test current, and a knee impedance of 1600Ω at 0.25mA. Reverse leakage current is 25µA at 1V reverse voltage. Forward voltage is 1.2V at 200mA forward current. The temperature coefficient is -0.070%/°C, indicating a slight negative drift with temperature.

 

The 1N5226B is housed in a DO-35 axial-lead package (DO-204AH), designed for through-hole mounting. This package is suitable for general-purpose voltage regulation, clamping, and reference applications in low-power circuits.
