1N5239B-TP

Single Zener Diodes Overview

The MCC 1N5239B-TP is a single silicon Zener diode housed in a DO-35 glass axial leaded package. It provides a nominal Zener voltage of 9.1 V with a 5% tolerance, tested at a current of 20 mA. The device supports a maximum DC power dissipation of 500 mW and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 3 µA at 7 V and a maximum Zener impedance of 10 Ω.

Single Zener Diodes Feature Summary

• Utilizes a hermetically sealed glass package for environmental stability
• Capable of high-temperature soldering at 260°C for 10 seconds
• Features a positive voltage temperature coefficient suitable for regulation above 5V

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TP' indicates tape-and-reel packaging containing 10,000 pieces per reel. Confirm RoHS compliance status and lead-free finish details directly with the manufacturer or authorized distributors, as these attributes are subject to change without notice.

Single Zener Diodes Selection Notes

Select this component when a through-hole 9.1 V Zener diode with 500 mW power handling is required. Ensure the application accounts for the positive temperature coefficient inherent to this voltage level. Verify that the operating environment stays within the specified -55°C to +150°C junction temperature range.

Single Zener Diodes Part Context

This part belongs to the 1N52xxB series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 75 V. The 'B' suffix specifically denotes a 5% voltage tolerance, distinguishing it from tighter tolerance variants.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the standard 1N5239B specification. Ensure any substitute matches the 9.1 V nominal voltage, 500 mW power rating, DO-35 package dimensions, and 5% tolerance requirements.
