1N5946B Description

Short technical summary and product information.

The 1N5946B is a 75V Zener diode from On Semiconductor, part of the 1N5913B series of 3W Zener voltage regulators. It features a nominal zener voltage of 75V with ±5% tolerance and a maximum power dissipation of 3W. The device offers a maximum zener impedance of 140Ω and a forward voltage of 1.5V at 200mA. Reverse leakage current is limited to 1µA at 56V.

 

This Zener diode is designed for voltage regulation and protection applications. It is housed in a DO-204AL (DO-41) axial lead package, suitable for through-hole mounting. The operating temperature range spans -65°C to 200°C, allowing use in demanding environments.

 

The 1N5946B provides reliable voltage clamping and regulation in power supplies, industrial controls, and consumer electronics. Its 3W power rating enables handling of moderate power dissipation in voltage reference and surge protection circuits.
