The 1N2974B is a 10W Zener diode with a nominal Zener voltage of 10V. It is housed in a hermetically sealed DO-203AA (DO-4) stud mount package, designed for robust power regulation applications.
Key electrical characteristics include a Zener impedance of 3 Ω, a reverse leakage current of 10 µA at 7.6V, and a forward voltage of 1.5V at 2A. The device operates over a junction temperature range of -65°C to +175°C and has a thermal resistance of 12°C/W junction-to-case.
The stud mount configuration with solder tab termination allows efficient heat sinking, making it suitable for high-reliability power supply and voltage reference circuits. The part is inherently radiation hard and nonsensitive to ESD per MIL-STD-750.
The Zener voltage is 10V.
The power dissipation is 10W.
It comes in a DO-203AA (DO-4) stud mount package.
The forward voltage is 1.5V at 2A.
The operating temperature range is -65°C to +175°C.
