JAN1N5524B-1/TR

Single Zener Diodes Overview

The JAN1N5524B-1/TR 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 features a maximum DC regulator current of 68 mA and a steady-state power dissipation of 0.5 W. The device operates within a junction temperature range of -65°C to +175°C. It utilizes a hermetically sealed axial-lead glass DO-35 (DO-204AH) package and includes an internal metallurgical bond.

Single Zener Diodes Feature Summary

• Qualified per MIL-PRF-19500/437 for JAN, JANTX, and JANTXV military reliability levels
• Features an internal metallurgical bond option indicated by the -1 suffix
• Provides guaranteed voltage regulation from the low regulator current to the test current
• Inherently radiation hard and nonsensitive to electrostatic discharge

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the specific order includes the -1 suffix to ensure the presence of the internal metallurgical bond required for JAN qualification. Confirm the B suffix corresponds to the required plus or minus 5 percent voltage tolerance. Ensure the TR suffix is present if tape and reel packaging is specified for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference with tight plus or minus 5 percent tolerance is required in harsh environments. The metallurgical bond construction provides superior mechanical stability compared to standard bonded variants. Verify that the 0.5 W power rating and DO-35 package dimensions fit the thermal and spatial constraints of the target application design.

Single Zener Diodes FAQ

What is the purpose of the -1 suffix in the part number?

The -1 suffix indicates that the device contains an internal metallurgical bond, which is a mandatory requirement for JAN, JANTX, and JANTXV military qualifications.

How is the polarity identified on the component?

Polarity is marked by a band on the glass body. For Zener regulation operation, the banded end must be connected to the positive potential relative to the opposite end.
