Overview
The Microchip Technology 1N4627-1 is a 500 mW Zener voltage regulator featuring an internal metallurgical bond and hermetically sealed glass DO-35 (DO-204AH) axial-leaded package. It provides a nominal Zener voltage of 6.2 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65 °C to +175 °C, exhibits a maximum reverse current of 5 µA at 5 V, and has a maximum dynamic impedance of 1200 Ohms.
Feature Summary
- Hermetically sealed construction utilizing an internal metallurgical bond for high reliability.
- Qualified per MIL-PRF-19500/435 standards for JAN, JANTX, JANTXV, and JANS levels.
- Inherently radiation hard as described in Microsemi MicroNote 050.
Applications
- Voltage regulation over broad ranges of current and temperature
- High reliability applications requiring MIL-qualified components
Procurement Notes
Verify the specific reliability level required, such as JAN, JANTX, JANTXV, or JANS, as these designations indicate different qualification standards under MIL-PRF-19500/435. Confirm whether RoHS compliance is necessary, noting that commercial versions may differ from military-grade specifications. Ensure the ordering suffix matches the desired packaging option, including tape and reel availability.
Selection Notes
Select this component when a 6.2 V reference is needed in a through-hole glass package. Consider the ±5% voltage tolerance and 1200 Ohm impedance limits against circuit requirements. Evaluate the operating temperature range up to +175 °C and power derating characteristics for thermal management. Verify compatibility with existing board layouts designed for the DO-35 footprint.
Part Context
This part belongs to the 1N4614-1 through 1N4627-1 series of 500 mW metallurgically bonded glass Zener diodes. The series covers voltages from 1.8 V to 100 V with various tolerance options. It shares the same package style and general electrical characteristics as other members in the family, differentiated primarily by their specific breakdown voltage ratings.

FAQ
What is the maximum noise density specification for the 1N4627-1?
The maximum noise density is 5 μV/√Hz at the test current of 250 μA.
How does the power dissipation rating change with temperature?
The 0.5 W rating must be linearly derated starting at a lead temperature of 50 °C and goes to zero at 175 °C.
