The 1N974B is a 36V Zener diode designed for voltage regulation and reference applications. With a nominal Zener voltage of 36V and a tolerance of ±5%, it provides stable voltage clamping. The maximum power dissipation is 500mW at lead temperature ≤75°C, derating at 4.0mW/°C above 75°C. The device is tested at 3.4mA with a maximum impedance of 70Ω. Maximum reverse leakage current is 5µA at 27.4V. It operates over a wide temperature range of -65°C to 200°C.
Packaged in a rugged DO-35 glass case with axial leads, the 1N974B is suitable for through-hole mounting. It belongs to the 1N957B-1N979B series of Zener diodes from ON Semiconductor (originally Fairchild Semiconductor). Typical applications include voltage regulation, overvoltage protection, and voltage reference in low-power circuits.
