1N5240C-TAP

Single Zener Diodes Overview

The Vishay 1N5240C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) glass axial package. It provides a nominal Zener voltage of 10 V with a tight ±2 % tolerance, indicated by the 'C' suffix. The device operates at a test current of 20 mA and dissipates up to 500 mW. Key electrical parameters include a maximum dynamic resistance of 17 Ω and a reverse leakage current of 3 μA at 7 V. The temperature coefficient is +0.075 %/K.

Single Zener Diodes Feature Summary

• Precision voltage regulation with ±2 % tolerance for stable reference applications
• Robust thermal performance with a junction temperature rating of 175 °C
• Low forward voltage drop of 1.1 V at 200 mA 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 includes the 'TAP' suffix to confirm the component is supplied in an ammpack format rather than reel packaging. Ensure the 'C' designation is present to guarantee the required ±2 % voltage tolerance. Confirm compliance with RoHS directives and material categorization standards before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 10 V reference is required with tighter tolerances than standard B-grade parts. The DO-35 package supports through-hole mounting. Verify that the operating current remains near the 20 mA test point to maintain accuracy. Consider the positive temperature coefficient for thermal stability requirements in the target application environment.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 series of small signal Zener diodes. The series covers a wide voltage range from 2.4 V to 75 V. The 1N5240 variant specifically targets the 10 V segment. The 'C' suffix denotes the tighter manufacturing tolerance compared to the standard 'B' grade.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same Vishay family include the 1N5240B for standard tolerance or other 1N52xx series devices if voltage levels differ. Cross-manufacturer equivalents must match the 10 V nominal voltage, 500 mW power dissipation, and DO-35 package dimensions.
