• Metallurgically bonded construction

Single Zener Diodes Applications

• Voltage regulation circuits
• Temperature compensated reference applications
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix against official documentation to confirm packaging configuration. The '/TR' designation indicates tape and reel packaging, which differs from bulk supply. Ensure compatibility with automated pick-and-place equipment specifications. Confirm that the lead finish meets project requirements.

Single Zener Diodes Selection Notes

Select this component when a low-profile, hermetically sealed surface-mount Zener diode is required. The DO-213AA package offers a compact footprint suitable for high-density PCB layouts. Verify that the thermal resistance characteristics align with the system's heat dissipation capabilities.

Single Zener Diodes Part Context

This part belongs to the 1N4370 series of Zener diodes manufactured by Microchip Technology. It shares the same electrical characteristics as the through-hole 1N4370A but utilizes a different surface-mount package. The series includes variants with different voltage ratings and tolerances.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA Zener diodes with identical 2.4V voltage rating and ±5% tolerance. Verify pinout polarity and thermal performance before substitution.
