1N4700/TR

Single Zener Diodes Overview

The Microchip Technology 1N4700/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 13 V with a tolerance of ±5%. The device operates in the DO-204AA (DO-7) axial through-hole package and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 50 nA, a test current of 50 µA, and a forward voltage of 1.1 V at 200 mA. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a 13 V Zener reference with standard 5% tolerance.
• Constructed with glass axial-leaded DO-7 packaging suitable for through-hole mounting.
• Capable of handling power dissipation up to 500 mW for reliable operation.

Single Zener Diodes Applications

• General-purpose voltage regulation circuits
• Reference voltage sources in electronic systems
• Overvoltage protection stages

Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates reel packaging when ordering. Confirm the manufacturer source, as Microchip acquired the relevant legacy lines. Ensure the DO-7 package dimensions match the target PCB footprint. Check for RoHS compliance status if required by project specifications. Validate the 500 mW power rating against thermal constraints in the final assembly.

Single Zener Diodes Selection Notes

Select this component for low-power axial applications requiring a 13 V reference. The DO-7 package offers a compact form factor for through-hole designs. Consider the 500 mW dissipation limit when designing heat management strategies. The wide temperature range supports operation in harsh environments. Verify that the 50 nA leakage current meets the sensitivity requirements of the circuit.

Single Zener Diodes Part Context

This part belongs to the 1N47xx series of 500 mW Zener diodes manufactured by Microchip Technology. The series provides a broad selection of voltage values in the DO-7 package. These components are widely used in industrial and consumer electronics for basic voltage stabilization tasks.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4700 variants in DO-7 packages. Ensure replacement parts maintain the 13 V nominal voltage and 500 mW power rating. Verify compatibility with the existing PCB layout and thermal design.
