JAN1N6334

Single Zener Diodes Overview

The JAN1N6334 is a military-qualified Zener voltage regulator from the 1N6309 through 1N6355 series, designed for high-reliability applications. It features a nominal Zener voltage of 27 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65 °C to +175 °C and dissipates up to 0.5 W at a lead temperature of 75 °C. Key electrical parameters include a maximum reverse leakage current of 10 µA at 25 °C and a dynamic impedance of 27 ohms at the test current of 4.6 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass package with internal metallurgical bonds
• Qualified per MIL-PRF-19500/533 for JAN reliability levels
• Inherently radiation hard construction
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• High-reliability aerospace systems
• Military electronic circuits
• Voltage regulation in extreme temperature environments

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required reliability level (JAN) and voltage tolerance. Confirm compliance requirements such as RoHS status, noting that commercial versions may differ from military specifications. Ensure the package type aligns with the intended mounting method before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a robust, hermetically sealed Zener diode is required for critical systems. Consider the thermal resistance values for derating calculations based on the specific operating environment. Verify that the 27 V breakdown voltage meets the circuit design requirements across the full specified temperature range.

Single Zener Diodes Part Context

This part belongs to the industry-standard 1N6309 through 1N6355 series of Zener diodes. The series offers a wide selection of voltages from 2.4 V to 200 V. The JAN variant specifically denotes a military qualification level, ensuring strict adherence to performance standards for defense and space applications.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANTX1N6334 and JANS1N6334, which offer different reliability tiers within the same MIL-PRF-19500/533 specification. Commercial equivalents like 1N6334 are available but lack the military qualification.
