1N4738A-TAP Description

Short technical summary and product information.

The 1N4738A-TAP is a silicon planar power Zener diode from Vishay Dale, designed for voltage stabilization and clipping circuits. It offers a nominal Zener voltage of 8.2V with a tolerance of ±5%. The device can dissipate up to 1.3W of power at 25°C ambient temperature when leads are kept at a distance of 4 mm from the case. Key electrical characteristics include a maximum forward voltage of 1.2V at 200 mA, a maximum reverse leakage current of 10 µA at 6 V, and a maximum dynamic resistance of 4.5 Ω at the test current. The junction temperature can reach up to 175°C, and the storage temperature range is -65°C to +175°C. The thermal resistance from junction to ambient is 110 K/W. The diode is housed in a DO-204AL (DO-41) axial leaded package, suitable for through-hole mounting. It is available in ammopack or tape and reel packaging options.
