JAN1N5524B-1

Single Zener Diodes Overview

The JAN1N5524B-1 is a low voltage avalanche Zener diode with a nominal breakdown voltage of 5.6 V at a test current of 3.0 mA. It operates within a junction temperature range of -65 °C to +175 °C and dissipates up to 0.5 W steady-state power. The device features a hermetically sealed axial-lead glass DO-35 package and includes an internal metallurgical bond. It is qualified per MIL-PRF-19500/437 for the JAN reliability level, ensuring high stability and radiation hardness.

Single Zener Diodes Feature Summary

• Hermetically sealed axial-lead glass construction with internal metallurgical bonding
• Qualified per MIL-PRF-19500/437 for JAN reliability levels
• Inherently radiation hard and non-sensitive to ESD
• Minimal capacitance suitable for broad operating ranges

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Military and aerospace electronic systems requiring high reliability
• Radiation-hardened circuit protection designs

Single Zener Diodes Procurement Notes

Verify that the ordering suffix explicitly includes the '-1' designation to confirm the presence of the internal metallurgical bond required for JAN qualification. Ensure the B suffix is present to guarantee the specified 5% voltage tolerance. Confirm compliance with MIL-PRF-19500/437 standards during procurement to validate the JAN reliability level and hermetic sealing requirements.

Single Zener Diodes Selection Notes

Select this component when a stable 5.6 V reference is required in harsh environments. The metallurgical bond option provides enhanced mechanical integrity compared to standard bonded versions. Verify that the 0.5 W power dissipation rating aligns with the thermal design constraints of the target application.

Single Zener Diodes Part Context

This part belongs to the 1N5518 through 1N5546 series of 0.5 W axial-leaded glass Zener Voltage Regulators. The series offers voltage selections from 3.3 to 33 volts with various tolerance options. The JAN variant specifically targets applications demanding strict military reliability standards and radiation resistance.

Single Zener Diodes Replacement Considerations

Equivalent parts must match the 5.6 V nominal voltage, 0.5 W power rating, and DO-35 package. Substitutes should also possess MIL-PRF-19500/437 JAN qualification and internal metallurgical bonding to maintain radiation hardness and hermetic sealing specifications.
