1N4135/TR

Single Zener Diodes Overview

The Microchip Technology 1N4135/TR is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides a nominal Zener voltage of 100 V with a standard tolerance of ±5%. The device operates within a junction and storage temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse current of 10 µA at 76 V, a maximum dynamic impedance of 1.6 kΩ, and a maximum noise density of 40 µV/√Hz.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for high reliability
• Hermetically sealed glass DO-35 axial-lead package
• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS levels
• Inherently radiation hard

Single Zener Diodes Applications

• High reliability voltage regulation
• Military and aerospace circuits
• Harsh environment applications requiring radiation hardness

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level (JAN, JANTX, JANTXV, or JANS) and RoHS compliance status. Confirm the tape and reel packaging format aligns with automated assembly requirements. Ensure the requested quantity meets factory consultation standards if not standard reel sizes.

Single Zener Diodes Selection Notes

Select this component when a 100 V Zener reference is needed in an axial-lead glass package. Consider the 1.6 kΩ dynamic impedance and 10 µA leakage limits against circuit requirements. Evaluate the metallurgical bond benefits for environments where mechanical shock or radiation resistance is critical.

Single Zener Diodes Part Context

This part belongs to the 1N4099-1 through 1N4135-1 series of 500 mW Zener diodes. The series offers voltages from 1.8 V to 100 V with various tolerance options. The 1N4135 represents the highest voltage point in this specific axial-lead lineup.

Single Zener Diodes Replacement Considerations

Substitutes must match the 100 V nominal voltage, 500 mW power rating, and DO-35 package. Verify equivalent MIL-PRF-19500/435 qualification levels if military grade performance is required.
