1N4100C/TR

Single Zener Diodes Overview

The Microchip Technology 1N4100C/TR is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides a nominal Zener voltage of 7.5 V with a tight 2% tolerance, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse leakage current of 5.7 µA at the specified test current of 250 µA. Dynamic impedance is rated at 200 Ohms, with a positive temperature coefficient of +0.065 %/°C.

Single Zener Diodes Feature Summary

• Metallurgically bonded construction for high reliability
• Hermetically sealed glass DO-35 axial-lead package
• Tight 2% voltage tolerance for precision regulation
• Qualified per MIL-PRF-19500/435 standards

Single Zener Diodes Applications

• High-reliability voltage reference circuits
• Precision voltage regulation in aerospace systems
• Temperature-compensated circuit designs
• Military-grade power supply protection

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required tolerance level and packaging format. Confirm RoHS compliance status if environmental regulations apply, as commercial versions may differ from qualified levels. Ensure the supplier provides documentation confirming the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for the application.

Single Zener Diodes Selection Notes

Select this component when a precise 7.5 V reference is needed with strict tolerance requirements. The 2% tolerance offers better accuracy than standard 5% variants. Consider the DO-35 package for through-hole mounting and the wide operating temperature range for harsh environments. Verify thermal derating requirements for high-power applications.

Single Zener Diodes Part Context

This part belongs to the 1N4099-1 through 1N4135-1 series of 500 mW Zener diodes. These devices are JEDEC registered and available in various tolerance grades and qualification levels. The series supports a broad voltage range from 1.8 V to 100 V, making it suitable for diverse industrial and military applications requiring robust voltage regulation.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 1N4100 variants with matching 7.5 V Zener voltage and 2% tolerance. Ensure replacement parts maintain the same DO-35 package dimensions and metallurgical bond construction. Verify that alternative sources offer equivalent MIL-PRF-19500/435 qualification levels if high reliability is required.
