The BZX85C18 is a Zener diode from On Semiconductor designed for voltage regulation and protection applications. It features a nominal Zener voltage of 18V with a tolerance of ±6%, and a maximum power dissipation of 1W at 25°C ambient temperature. The device offers a maximum Zener impedance of 20 Ω at a test current of 15 mA, and a knee impedance of 500 Ω at 0.5 mA.
This diode is housed in a DO-204AL (DO-41) axial leaded glass package, suitable for through-hole mounting. It operates over a wide temperature range from -65°C to 200°C, with a derating factor of 6.67 mW/°C above 50°C. The maximum forward voltage is 1.2V at 200 mA, and the leakage current is limited to 0.5 µA at 12.5V reverse voltage.
Typical applications include voltage clamping, overvoltage protection, and reference voltage generation in power supplies and industrial electronics. The robust glass package ensures reliability in demanding environments.
The nominal Zener voltage is 18V, with a range of 16.8V to 19.1V.
Maximum power dissipation is 1W at 25°C ambient temperature, and 1.3W at 25°C lead temperature.
The device is available in a DO-204AL (DO-41) axial leaded through-hole package.
The operating and storage temperature range is -65°C to 200°C.
Maximum forward voltage is 1.2V at a forward current of 200 mA.
