Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANS) required for your application, as the base part number may correspond to different military grades. Confirm that the TR suffix indicates tape and reel packaging if automated assembly is planned. Ensure compliance with MIL-PRF-19500/435 requirements for your specific environmental constraints.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V Zener reference is needed in a glass axial package. Consider the 500 mW power limit and the wide operating temperature range for harsh environments. Verify that the 5% tolerance meets your circuit's accuracy requirements compared to tighter tolerance alternatives.

Single Zener Diodes Part Context

This component belongs to the 1N4614 through 1N4627 series of 500 mW metallurgically bonded glass Zener diodes. These devices are JEDEC registered and offer voltages from 1.8 V to 100 V. They are designed for high-reliability use and are available in various qualification levels including JAN, JANTX, JANTXV, and JANS.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 1N4627 variants such as 1N4627B or 1N4627D, provided they match the 6.2 V nominal voltage, 500 mW power rating, and DO-35 package form factor. Verify that any replacement meets the same MIL-PRF-19500/435 qualification level.
