1N5243B-TAP

Single Zener Diodes Overview

The 1N5243B-TAP is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 13 V with a standard tolerance of ±5%. The device operates in the DO-35 (DO-204AH) axial through-hole package and supports a maximum power dissipation of 500 mW at thermal equilibrium. Key electrical characteristics include a test current of 9.5 mA, a reverse leakage current of 0.5 µA at 9.9 V, and a dynamic resistance of 13 Ω at the test current.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features a standard ±5% Zener voltage tolerance designated by the 'B' suffix
• Designed for high junction temperature operation up to 175 °C

Single Zener Diodes Applications
