The Vishay Dale 1N4746A-TR is a silicon planar power Zener diode designed for voltage stabilization and clipping circuits requiring high power rating. It offers a nominal Zener voltage of 18V with a standard tolerance of ±5%.
Key electrical characteristics include a maximum power dissipation of 1.3W (tp=10 ms, leads at 4 mm from case at ambient), a maximum forward voltage of 1.2V at 200 mA, and a maximum reverse leakage current of 5 µA at 13.7V. The dynamic resistance is 20 Ω maximum at 1 kHz.
The device is housed in a DO-204AL (DO-41) through-hole package with axial leads, suitable for manual and automated assembly. It is rated for operation up to 175°C junction temperature and can be stored from -65°C to +175°C. The thermal resistance from junction to ambient is 110 K/W.
