1N4746A-TAP Description

Short technical summary and product information.

The 1N4746A-TAP is a Zener diode from Vishay Semiconductors, part of the 1N4728A to 1N4761A series. It features a nominal Zener voltage of 18V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1.3W (at tp=10ms, leads at 4mm from case at ambient temperature). Electrical characteristics include a maximum forward voltage of 1.2V at 200mA forward current, a maximum reverse leakage current of 5µA at 13.7V reverse voltage, and a maximum dynamic resistance of 20Ω at the unspecified test current. The junction temperature can reach up to 175°C, with a storage temperature range of -65 to +175°C. The thermal resistance from junction to ambient is 110 K/W under the same test conditions. The diode is housed in a DO-204AL (DO-41) through-hole package with axial leads, weighing approximately 310 mg. The package is rated UL 94 V-0 for flammability, MSL level 1 (unlimited), and supports a peak soldering temperature of 260°C. This component is suitable for voltage stabilization, clipping, and clamping circuits in various electronic applications.
