The 1N3305B is a 50-watt Zener diode designed for voltage regulation in high-power applications. It is housed in a rugged DO-5 (DO-203AB) stud mount package, which provides excellent thermal performance when properly mounted with a heatsink. The device offers a maximum power dissipation of 50W at a case temperature below 75°C, with a derating factor of 0.5 W/°C above that temperature.
Key electrical characteristics include a maximum forward voltage of 1.5V at 10A, a maximum Zener impedance (Zzt) of 0.2Ω, and a maximum leakage current of 150µA at a reverse voltage of 4.5V. The device operates over a junction temperature range of -65°C to 175°C and has a maximum thermal resistance of 2.0°C/W from junction to base.
The 1N3305B is part of the JEDEC-registered 1N3305 through 1N3350B series and is available with a ±5% voltage tolerance. The package is hermetically sealed and suitable for stud mounting, making it ideal for industrial and military-grade power regulation circuits.
