1N4907

Single Zener Diodes Overview

The Microchip Technology 1N4907 is a temperature-compensated Zener reference diode designed for precision voltage regulation applications. It features a nominal Zener voltage of 12.8 V with a tight tolerance of ±5%. The device is housed in a DO-7 through-hole package and supports a power dissipation of 400 mW. Key electrical characteristics include a maximum reverse leakage current of 15 uA and a peak forward current rating of 250 mA. It operates within a temperature range of -65°C to +200°C, ensuring stability across extreme environmental conditions.

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., /TR for tape and reel) against project requirements, as packaging affects handling. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation, as regulatory markings can vary by production batch. Ensure the DO-7 package footprint matches the PCB layout before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 12.8 V reference is required under varying thermal conditions. The 400 mW power rating suits moderate current applications. Compare leakage current specifications against other Zener types if ultra-low noise is critical. Ensure the operating temperature range aligns with the system's environmental constraints.

Single Zener Diodes Part Context

This part belongs to the family of temperature-compensated Zener diodes manufactured by Microchip Technology. Unlike standard Zener diodes, these are engineered to minimize voltage drift over wide temperature ranges. The 1N4907 specifically targets applications requiring high accuracy without external compensation networks, distinguishing it from general-purpose rectifier or standard regulation diodes.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 12.8 V nominal voltage, ±5% tolerance, and temperature-compensated characteristic. Verify that alternative components offer comparable power dissipation and leakage current specs. Standard Zener diodes lacking temperature compensation are not suitable replacements for precision reference applications.
