1N5240C-TR

Single Zener Diodes Overview

The Vishay 1N5240C-TR 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 reverse leakage current of 3 µA at 7 V, a typical dynamic resistance of 17 Ω at 20 mA, and a temperature coefficient of +0.075 %/K.

Single Zener Diodes Feature Summary

• High-precision voltage regulation with ±2 % tolerance for stable reference applications
• Robust thermal performance supporting continuous operation up to 175 °C junction temperature
• Low forward voltage drop ensuring minimal power loss during conductive states

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision voltage references
• Overvoltage protection networks

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to confirm the ±2 % tolerance specification. Ensure the '-TR' suffix matches the required taped-and-reeled packaging format. Cross-reference the document number 85588 to access the latest technical specifications and ensure compliance with RoHS directives.

Single Zener Diodes Selection Notes

Select this component when circuit requirements demand tighter voltage accuracy than standard ±5 % devices provide. The 10 V rating suits mid-range reference needs, while the DO-35 package facilitates through-hole mounting. Evaluate the positive temperature coefficient (+0.075 %/K) against the operating environment's thermal profile.

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, offering a balance between low leakage and moderate dynamic impedance suitable for general-purpose regulation tasks.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include the 1N5240B (±5 % tolerance) and the 1N5240 (generic). Verify that alternative manufacturers offer equivalent DO-35 packages and matching 10 V Zener characteristics.
