1N5240B-TR

Single Zener Diodes Overview

The Vishay 1N5240B-TR is a silicon planar power Zener diode in the 1N5221 to 1N5267 series, housed in a DO-35 (DO-204AH) glass package. It provides a nominal Zener voltage of 10 V with a standard tolerance of ±5%. 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 8 V, a typical dynamic resistance of 17 Ω, and a temperature coefficient of 0.075 %/K. It supports a junction temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features a hermetically sealed glass DO-35 axial leaded package
• Provides stable reference voltages across a wide thermal operating range

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the B suffix to confirm the ±5% voltage tolerance specification. Ensure the -TR designation matches the required reel packaging format for automated assembly processes. Cross-reference the document number 85588 to access the latest technical specifications and dimensional drawings before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 10 V reference point is required within a through-hole design. The 500 mW power rating allows for moderate current handling in standard signal applications. Verify that the circuit environment remains within the specified -65 °C to +175 °C operating temperature limits to ensure long-term reliability and performance stability.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N52xxB series of small signal Zener diodes. The series covers a broad voltage spectrum from 2.4 V to 75 V, utilizing consistent DO-35 packaging. The 'B' suffix specifically denotes the standard ±5% manufacturing tolerance, distinguishing it from tighter tolerance variants like the 'C' series.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same Vishay family include 1N5240B-TAP and 1N5240B-series-TR. Other manufacturers producing JEDEC-compliant 1N5240 devices in the DO-35 package may serve as functional equivalents if electrical parameters align.
