The 1N3315B is a 50 watt Zener diode from Solid State Devices Inc. (SSDI) in a DO-5 (DO-203AB) stud mount package. It provides voltage regulation with a standard tolerance of ±5%. Key electrical specifications include a maximum Zener impedance of 1.6Ω, a forward voltage of 1.5V at 10A, and a reverse leakage current of 5µA at 12.2V. The device can operate over a junction temperature range of -65°C to 175°C. Power dissipation is rated at 50W for case temperatures below 75°C, with a derating factor of 0.5W/°C above 75°C. Thermal resistance from junction to base is 2.0°C/W (typical 1.5°C/W). The hermetically sealed DO-5 package with 1/4-28 threaded stud ensures excellent thermal management when mounted to an appropriate heat sink. This Zener diode is suitable for high-power regulation, overvoltage protection, and industrial power supplies requiring robust performance. It is also available in military-qualified versions (JAN, JANTX, JANTXV).
