JAN1N5542BUR-1/TR

Single Zener Diodes Overview

The JAN1N5542BUR-1/TR is a military-grade Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 22 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. It utilizes the DO-213AA surface mount package. Key electrical characteristics include a maximum impedance of 100 Ohms, a reverse leakage current of 10 nA at 19.8 V, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Qualified per MIL-PRF-19500/437 for military applications
• Glass surface mount construction in DO-213AA package
• Wide operating temperature range from -65°C to +175°C

Single Zener Diodes Applications

• Military electronic systems requiring regulated voltage references
• High-reliability circuit protection designs
• Avionics and aerospace equipment power management

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape and reel packaging if required for automated assembly processes. Confirm that the JAN prefix denotes full military qualification standards as specified in the official datasheet. Ensure compatibility with the DO-213AA footprint during PCB layout. Check for any recent Product Change Notifications regarding assembly sites or labeling changes before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 22 V regulation point is needed in space-constrained surface mount designs. The 500 mW power rating supports moderate current loads. The wide thermal range makes it suitable for harsh environments where standard commercial parts would fail. Verify that the 100 Ohm impedance meets the noise and stability requirements of the target application circuit.

Single Zener Diodes Part Context

This part belongs to the 1N5518BUR-1 through 1N5546BUR-1 series of low-voltage avalanche Zener diodes. The series offers voltages from 3.3 to 33 volts with various tolerance options. These devices are designed for high-reliability applications using glass surface mount technology. The BUR-1 designation typically aligns with specific military qualification packages.

Single Zener Diodes Replacement Considerations

The non-trailing slash version JAN1N5542BUR-1 is a parameter-equivalent alternative. Verify if bulk packaging is acceptable instead of the tape and reel format indicated by the /TR suffix. Other voltages in the 1N5542 series family may serve as functional substitutes if the voltage level can be adjusted.
