1N4744AG

Overview

The Microchip Technology 1N4744AG is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a tolerance of ±5%. The device is housed in a DO-41 axial leaded package, suitable for through-hole mounting. It supports a maximum power dissipation of 1 W and operates within a temperature range from -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 25 Ohms, and a test current of 10.5 mA.

Feature Summary

• Provides stable voltage regulation at a nominal 15 V level
• Capable of handling up to 1 W of power dissipation
• Operates reliably across an extended industrial temperature range

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Procurement Notes

Verify the specific suffix 'AG' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the required quantity aligns with reel specifications if applicable. Cross-reference the part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a precise 15 V regulation point is required in through-hole designs. Consider the 1 W power rating and thermal management needs for the operating environment. Verify that the ±5% voltage tolerance meets the circuit requirements and that the axial package fits the PCB layout constraints.

Part Context

This component belongs to the standard 1N47xx series of Zener diodes manufactured by Microchip Technology. These devices are widely used in general-purpose electronics for voltage stabilization. The 1N4744AG variant specifically denotes the 15 V version within this family, sharing common mechanical and electrical traits with adjacent voltage ratings.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4744A or 1N4744 parts with matching 15 V, 1 W, and DO-41 specifications. Ensure equivalent Zener impedance and leakage current ratings are met for critical performance.
