1N5242B-TAP

Single Zener Diodes Overview

The 1N5242B-TAP is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 12 V with a standard tolerance of ±5%. The device operates in the DO-35 (DO-204AH) axial through-hole package and dissipates up to 500 mW at thermal equilibrium. Key electrical characteristics include a maximum dynamic resistance of 30 Ohms, a reverse leakage current of 1 µA at 9.1 V, and a typical temperature coefficient of 0.077 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for high stability and sharp reverse characteristics
• Provides low reverse leakage current levels for precise regulation
• Features a standard ±5% Zener voltage tolerance designated by the 'B' suffix

Single Zener Diodes Applications

• Voltage stabilization

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the TAP suffix to confirm the specific ammopack packaging format. Ensure compliance with RoHS3 standards and confirm the material categorization requirements for your region before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 12 V reference with ±5% accuracy is required in an axial leaded package. Consider the 30 Ohm dynamic impedance and 0.077 %/K temperature coefficient for circuit design constraints. Verify that the 500 mW power dissipation rating aligns with the expected operating conditions.
