1N5241B-TR

Single Zener Diodes Overview

The Vishay 1N5241B-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) through-hole package. It provides an 11 V nominal Zener voltage with a ±5% tolerance, tested at 20 mA. The device dissipates up to 500 mW and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 2 µA at 8.4 V and a typical dynamic resistance of 22 Ω at 20 mA.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation

• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'B' suffix to confirm the required ±5% voltage tolerance. Ensure the '-TR' suffix matches the reel packaging requirement for automated assembly processes. Cross-reference the specific document revision against the manufacturer's official database to validate all electrical parameters before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a standard 11 V reference point is required in through-hole designs. The 500 mW power rating supports moderate current loads without excessive heating. Verify that the operating environment remains within the specified -65 °C to +175 °C junction temperature limits to maintain performance stability.

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, utilizing standardized DO-35 glass packages. The 'B' designation specifically denotes the tighter ±5% manufacturing tolerance compared to standard variants.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same Vishay series include other 1N52xxB devices with matching voltage ratings. Alternative manufacturers producing equivalent DO-35 Zener diodes must be verified against the absolute maximum ratings and thermal characteristics provided in the datasheet.
