The 1N975B is a 39V Zener Diode from ON Semiconductor, part of the 1N957B-1N979B series. It features a nominal zener voltage of 39V with a tolerance of ±5%, ensuring precise voltage regulation. The diode can dissipate up to 500mW of power at lead temperatures up to 75°C, with a derating factor of 4.0 mW/°C above 75°C.
Electrical characteristics include a maximum dynamic impedance of 80Ω at a test current of 3.2mA, and a low reverse leakage current of 5µA at 29.7V. The device is designed for general purpose voltage regulation, overvoltage protection, and clamping applications.
The 1N975B is packaged in a DO-35 (DO-204AH) axial lead through-hole package, suitable for manual or automated insertion. It operates over a wide temperature range of -65°C to 200°C, making it suitable for demanding environments.
