The 1N2999B is a 10W Zener diode with a nominal Zener voltage of 43V and ±5% tolerance. It exhibits a maximum impedance of 16Ω and a reverse leakage current of 5µA at 42.6V. The forward voltage is 1.5V at 2A.
The device operates over a junction temperature range of -65°C to 175°C, with a thermal resistance of 12°C/W junction-to-case. Power must be derated at 0.083W/°C above a case temperature of 55°C. It is designed for voltage regulation and overvoltage protection in power supplies and industrial systems.
The 1N2999B is packaged in a standard DO-4 (DO-203AA) stud mount package with a 10-32 thread stud lead style. The hermetically sealed welded construction provides robust environmental protection. The unit weighs approximately 7.5g.
