1N4107 (DO35)

Single Zener Diodes Overview

The Microsemi Corporation 1N4107 is a Zener voltage regulator diode housed in an axial-lead glass DO-35 (DO-204AH) package. It features an internal metallurgical bond and provides a nominal Zener voltage of 13V at a test current of 250 µA. The device supports a maximum power dissipation of 0.5W, with a maximum dynamic impedance of 0.05 Ω and a maximum reverse current of 9.9 µA. It operates within a junction temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm the required qualification level, as the base part number covers commercial through JANS grades. Ensure the selected variant meets the necessary environmental screening requirements for your application. Confirm RoHS compliance status if lead-free terminals are mandatory, noting that this attribute applies only to commercial grade versions.

Single Zener Diodes Selection Notes

Select the 1N4107 when a 13V Zener reference is needed in a hermetically sealed glass package. Consider the internal metallurgical bond for enhanced durability in harsh environments. Evaluate the thermal derating curve to ensure adequate heat dissipation at elevated ambient temperatures. Verify that the low dynamic impedance meets the stability requirements of the target circuit design.

Single Zener Diodes Part Context

This component belongs to the 1N4099-1 through 1N4135-1 series of 500 mW metallurgically bonded glass Zener diodes manufactured by Microsemi. These devices are designed for applications demanding high reliability and radiation hardness. The series offers a wide selection of voltages from 1.8V to 100V with various tolerance options.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N4107 variants from different manufacturers that match the 13V Zener voltage, 0.5W power rating, and DO-35 package dimensions. Ensure any substitute also possesses the required metallurgical bond and hermetic sealing characteristics if operating in extreme conditions.
