The 1N3317RB is a 50-watt Zener diode from Solid State Devices Inc (SSDI), designed for voltage regulation in high-power applications. It provides a nominal Zener voltage of 18V with a tolerance of ±5%. The device features a low maximum impedance of 2Ω and a forward voltage of 1.5V at 10A. Reverse leakage current is 5µA at 13.7V.
This diode is housed in a hermetically sealed DO-203AB (DO-5) stud mount package, suitable for chassis mounting with adequate heat sinking. It operates over a junction temperature range of -65°C to +175°C. The R suffix indicates reverse polarity (cathode to case).
Typical applications include voltage regulation in power supplies, industrial equipment, and military/aerospace systems where high reliability and power dissipation are required. The part is RoHS3 compliant and REACH unaffected.
