1N4133-1

Single Zener Diodes Overview

The Microchip Technology 1N4133-1 is a 500 mW metallurgically bonded glass Zener diode in the axial-leaded DO-35 package. It provides an 87 V nominal Zener voltage with a test current of 250 µA and maximum impedance of 0.01 Ohms. The device operates within a junction temperature range of -65 °C to +175 °C, features a maximum noise density of 66.2 µV/√Hz, and has a temperature coefficient of +0.100 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed internal metallurgical bond for high reliability
• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS levels
• Inherently radiation hard design suitable for harsh environments

Single Zener Diodes Applications

• High-reliability voltage regulation circuits
• Radiation-hardened electronic systems
• Precision reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as this affects qualification standards. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from military grades. Ensure the ordering suffix matches the desired tolerance and packaging configuration before finalizing procurement.

Single Zener Diodes Selection Notes

Select the 1N4133-1 when an 87 V Zener reference is needed in a hermetically sealed axial package. Consider its low dynamic impedance and stable temperature coefficient for precision applications. Evaluate the available reliability qualifications against environmental stress requirements to ensure long-term operational stability.

Single Zener Diodes Part Context

This component belongs to the 1N4099-1 through 1N4135-1 series of 500 mW Zener diodes manufactured by Microchip Technology. These devices are designed for demanding environments requiring robust voltage regulation and are distinguished by their metallurgically bonded construction and extensive military-grade qualification options.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N4133 variants from different manufacturers offering identical 87 V specifications and DO-35 packages. Verify that substitute parts meet the same MIL-PRF-19500/435 reliability standards and thermal characteristics if operating in extreme conditions.
