1N3015B Description

Short technical summary and product information.

The 1N3015B is a 10W Zener diode from Microchip Technology, part of the industry-standard 1N2970B–1N3015B series. It provides a nominal Zener voltage of 200V with ±5% tolerance, making it suitable for precise voltage regulation in demanding applications.

 

Electrical characteristics include a maximum Zener impedance of 300Ω, a reverse leakage current of 10µA at 152V, and a forward voltage of 1.5V at 2A. The device is rated for continuous power dissipation of 10W at a case temperature of 55°C, with derating above that temperature.

 

The diode is packaged in a hermetically sealed DO-203AA (DO-4) stud mount case with standard polarity (anode to stud). It operates over a junction temperature range of -65°C to +175°C. The stud mount design allows for efficient heat sinking in chassis-mounted applications.
