The BZX85C3V9 is a 3.9V Zener diode from On Semiconductor designed for voltage regulation and protection applications. It offers a nominal Zener voltage of 3.9V with a tolerance of ±5%, ensuring reliable voltage clamping. The diode can dissipate up to 1 watt of power, making it suitable for moderate power circuits.
With a maximum impedance of 15Ω (Zzt), the device maintains stable regulation over a range of currents. The forward voltage is 1.2V at 200mA, and the reverse leakage current is limited to 5µA at 1V. The operating junction temperature range spans from -65°C to 200°C, allowing use in harsh environments.
This Zener diode is commonly used in shunt regulators, overvoltage protection, and reference voltage circuits. The through-hole DO-204AL (DO-41) package facilitates easy insertion on printed circuit boards and prototyping. The component is RoHS3 compliant and has an MSL of 1 (unlimited).
