1N5242C-TAP

Single Zener Diodes Overview

The Vishay 1N5242C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 12 V with a tight tolerance of ±2%, tested at 20 mA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range up to 175 °C. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 9.1 V, a typical dynamic resistance of 30 Ω, and a voltage temperature coefficient of 0.077 %/K.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2% Zener voltage tolerance
• Robust thermal performance supporting operation up to 175 °C junction temperature
• Low leakage current characteristics for efficient circuit isolation

Single Zener Diodes Applications

• Voltage stabilization circuits

• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code suffix 'TAP' corresponds to the specific ammopack tape configuration required for your assembly line. Confirm the component matches the DO-35 package dimensions and lead specifications outlined in the datasheet. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this variant when a tighter voltage tolerance than the standard ±5% is required. The 12 V rating suits applications needing precise reference levels. Consider the 500 mW power dissipation limit and thermal resistance constraints during PCB layout to ensure reliable operation under continuous load conditions.

Single Zener Diodes Part Context

This component belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide Zener voltage range from 2.4 V to 75 V. The 'C' suffix specifically denotes the ±2% tolerance grade, distinguishing it from the standard 'B' grade devices within the same product family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 12 V Zener diodes in the DO-35 package with ±2% tolerance. Verify equivalent power ratings and thermal characteristics to ensure direct replacement compatibility without circuit modification.
