BZX79C3V3 Description

Short technical summary and product information.

The BZX79C3V3 is a Zener diode manufactured by On Semiconductor, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 3.3V with a tolerance of ±5%. The device can dissipate up to 500mW of power, making it suitable for low-power circuits.

 

Electrical characteristics include a maximum forward voltage of 1.5V at 100mA, a reverse leakage current of 25µA at 1V, and a maximum Zener impedance of 95Ω. The operating temperature range spans from -65°C to 200°C, allowing use in harsh environments.

 

The diode is housed in a DO-35 (DO-204AH) through-hole package with axial leads, compatible with standard PCB mounting. It is commonly used in voltage clamping, reference voltage generation, and overvoltage protection in consumer and industrial electronics.
