1N5242C-TR

Single Zener Diodes Overview

The Vishay 1N5242C-TR 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%. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Key electrical parameters include a maximum reverse leakage current of 1 µA at 9.1 V, a dynamic resistance of 30 Ω at a test current of 20 mA, and a typical 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 a 175 °C junction temperature
• Low leakage current characteristics for efficient circuit isolation

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific suffix required for the desired packaging format. Confirm compliance with RoHS directives and material categorization standards before finalizing procurement. Ensure the selected component meets the specific environmental requirements of the target application.

Single Zener Diodes Selection Notes

Select this component when a precise 12 V reference is required with tighter tolerances than standard variants. Evaluate the thermal resistance and lead length constraints to ensure the 500 mW power dissipation rating is maintained under operating conditions. Compare against other series members if different voltage levels are needed.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of nominal voltages from 2.4 V to 75 V. The 'C' suffix specifically denotes the tighter ±2% tolerance variant compared to the standard ±5% 'B' suffix devices.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same Vishay series include 1N5242B-TR for standard tolerance applications. Cross-manufacturer equivalents should be verified against the specific electrical parameters and package dimensions provided in the datasheet.
