1N5240BTR

Single Zener Diodes Overview

The 1N5240BTR is a single silicon Zener diode manufactured by Fairchild Semiconductor, designed for voltage regulation applications. It features a nominal Zener voltage of 10 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW and operates within an ambient temperature range of -65°C to +200°C. Packaged in the DO-204AH (DO-35) axial through-hole format, it exhibits a maximum reverse leakage current of 100 nA at 10 V and a forward voltage drop of 1.2 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Utilizes glass-passivated silicon junction for environmental durability
• Supports high thermal stability with extended operating temperature limits

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection stages
• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify that the ordering suffix corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm compliance with RoHS directives and material declarations prior to integration into production lines. Ensure the component status remains active and available from authorized distribution channels to maintain supply chain continuity.

Single Zener Diodes Selection Notes

Select this component when a 10 V regulation point is required in a through-hole design. The DO-35 package accommodates standard PCB mounting techniques. Evaluate the 500 mW power rating against expected circuit dissipation to ensure safe operation under continuous load conditions without exceeding thermal limits.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of low-power Zener diodes widely used in discrete semiconductor designs. The 'B' suffix typically denotes a tighter voltage tolerance compared to standard variants. Fairchild Semiconductor, now part of onsemi, produces this component as a reliable solution for general-purpose voltage regulation tasks in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Compatible substitutes include Vishay 1N5240B and Microsemi MX1N5240B-1TR. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet identical electrical specifications for voltage, power, and tolerance.
