Overview
The Microchip Technology 1N4627-1/TR is a 500 mW metallurgically bonded glass Zener diode in an axial-lead DO-35 package. It provides a nominal Zener voltage of 6.2 V at a test current of 250 µA, with a maximum dynamic impedance of 1200 Ohms and a maximum reverse leakage current of 5 µA. The device operates within a junction temperature range of -65 °C to +175 °C. The 'TR' suffix indicates tape and reel packaging per EIA-296 standards.
Feature Summary
- Internal metallurgical bond construction for high reliability
- Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS levels
- Hermetically sealed glass DO-35 package
- Inherently radiation hard
Applications
- High reliability voltage regulation
- Military and aerospace circuits
- Harsh environment applications requiring radiation hardness
Procurement Notes
Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number covers multiple qualification grades. Confirm that the TR suffix corresponds to the necessary tape and reel packaging format. Ensure compliance with MIL-PRF-19500/435 standards if military-grade performance is mandated.
Selection Notes
Select this component when a stable 6.2 V reference is needed in a through-hole axial package. Consider the 1200 Ohm impedance limit for low-current precision applications. Evaluate the thermal derating curve if operating near the upper temperature limits. Verify that the 500 mW power dissipation rating meets the circuit's peak load requirements.
Part Context
This part belongs to the 1N4614-1 through 1N4627-1 series of 500 mW Zener diodes. These devices are JEDEC registered and offer voltages from 1.8 V to 100 V. They are designed for robust performance in demanding environments, featuring low noise density characteristics above 6.8 V.
Replacement Considerations
Direct replacements include other manufacturers' 1N4627 variants meeting the same electrical specifications. For higher reliability needs, consider JANTX or JANS qualified versions of the same part number. Surface mount equivalents are available in DO-213AA packages.
