JAN1N5527D-1

Single Zener Diodes Overview

The JAN1N5527D-1 is a low voltage avalanche Zener diode qualified per MIL-PRF-19500/437. It features a hermetically sealed axial-lead glass DO-35 package with an internal metallurgical bond. The nominal Zener voltage is 7.5 V at a test current of 1 mA, with a maximum dynamic impedance of 35 Ohms and a maximum reverse leakage current of 6.0 µA. It operates within a junction temperature range of -65 to +175 °C and dissipates up to 0.5 W.

Single Zener Diodes Feature Summary

• Hermetically sealed axial-lead glass construction with internal metallurgical bonding
• Qualified for military reliability standards including radiation hardness
• ESD insensitive per MIL-STD-750 Method 1020
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Reference voltage sources in harsh environments
• Protection circuits requiring high reliability

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the datasheet nomenclature table to ensure the correct tolerance level and metallurgical bond option are ordered. Confirm that the required qualification level matches the project specifications. Check for RoHS compliance requirements as this military grade part may differ from commercial equivalents.

Single Zener Diodes Selection Notes

Select this component when strict military reliability and radiation hardness are required. The D suffix indicates a tight 1% voltage tolerance. Ensure the application can accommodate the specified thermal resistance and power derating curves. Verify lead solderability requirements against MIL-STD-750 methods.

Single Zener Diodes Part Context

This device belongs to the 1N5518 thru 1N5546 series of 0.5 watt axial-leaded glass Zener Voltage Regulators. The series provides voltages from 3.3 to 33 volts. The JAN prefix denotes a specific reliability level under the MIL-PRF-19500/437 specification.

Single Zener Diodes Replacement Considerations

Commercial equivalents include the 1N5527B or 1N5527D without the JAN prefix. Surface mount alternatives exist in the DO-213AA MELF package (e.g., 1N5527BUR-1). Verify pinout compatibility and thermal performance before substitution.
