1N4761A-TAP

Single Zener Diodes Overview

The Vishay 1N4761A-TAP is a silicon planar power Zener diode in the 1N4728A to 1N4761A series, housed in an axial DO-41 (DO-204AL) package. It provides a nominal Zener voltage of 75 V with a standard tolerance of ± 5 %. The device operates at a test current of 3.3 mA and dissipates up to 1300 mW of power. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 56 V and a dynamic impedance of 175 Ω at the test current. It supports a surge current of 2000 mA and functions within a junction temperature range of -65 °C to +175 °C.
