1N5237C-TAP

Single Zener Diodes Overview

The Vishay 1N5237C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides an 8.2 V nominal Zener voltage with a tight ±2% tolerance, indicated by the 'C' suffix. 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 characteristics include a maximum reverse leakage current of 3 µA at 6.5 V, a typical dynamic resistance of 8 Ω at 6.5 mA, and a positive temperature coefficient of 0.062 %/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 forward voltage drop for efficient circuit integration

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'TAP' suffix to ensure receipt of the component in ammopack tape format rather than reel packaging. Confirm the 'C' designation matches the required ±2% tolerance specification. Cross-reference the document number 85588 to access the latest technical specifications and compliance documentation before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this specific part when a precise 8.2 V reference is required alongside strict tolerance limits. The DO-35 axial package facilitates through-hole mounting on standard printed circuit boards. Ensure the application design accounts for the 500 mW power dissipation limit and the resulting thermal resistance requirements under continuous operating 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 1N5237 variant specifically targets the 8.2 V segment, offering distinct electrical parameters compared to adjacent voltage ratings within the same product family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5237B-TAP for applications accepting ±5% tolerance, or the MMSZ5237C-E3-18 for surface mount implementations requiring identical electrical characteristics.
