Overview
The Microchip Technology 1N4744AGE3 is a silicon planar power Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a 5% tolerance, tested at 17 mA. The device operates in the DO-41 axial through-hole package and dissipates up to 1 W of power. Key electrical characteristics include a maximum reverse leakage current of 5 uA, a Zener impedance of 14 Ohms, and a forward voltage of 1.2 V at 200 mA. It supports an operating temperature range from -65 C to +175 C.
Feature Summary
- Provides stable voltage regulation using silicon planar technology
- Features low reverse leakage current for improved circuit efficiency
- Supports high thermal stability across extended temperature ranges
Applications
- Voltage reference circuits
- Overvoltage protection systems
- Power supply regulation
Procurement Notes
Verify the specific suffix 'E3' confirms RoHS compliance and lead-free status as per manufacturer documentation. Confirm the package type matches the required DO-41 axial form factor for your PCB layout. Ensure the 1W power dissipation rating aligns with your thermal management design constraints.
Selection Notes
Select this component when a precise 15 V reference is required in an axial package. Compare against standard 1N4744 variants if RoHS compliance is mandatory. Consider the 14 Ohm impedance value for dynamic load regulation requirements. Verify that the 17 mA test current fits within your biasing network capabilities.
Part Context
This part belongs to the 1N47xx series of power Zener diodes manufactured by Microchip Technology. It serves as a lead-free, RoHS-compliant alternative to older non-compliant versions like the 1N4744G. The series is widely used in industrial and commercial electronics requiring reliable voltage clamping.
Replacement Considerations
The 1N4744A is the primary equivalent without RoHS certification. Surface mount equivalents such as CDLL4744A offer similar electrical performance in a different package format.
