Overview
The Microchip Technology 1N5518/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.3 V with a 5% tolerance and operates at a test current of 20 mA. The device has a maximum power dissipation of 500 mW and a Zener impedance of 26 Ohms. It supports a reverse leakage current of up to 5 uA and a forward current of 200 mA. The component is housed in a DO-204AH (DO-35) axial through-hole package, suitable for reel packaging, and functions within a temperature range of -65°C to +175°C.
Feature Summary
- Provides stable voltage regulation with low reverse leakage characteristics
- Capable of handling high junction temperatures for robust operation
- Designed for through-hole mounting in standard axial packages
Applications
- Voltage reference circuits
- Overvoltage protection
- General-purpose voltage regulation
Procurement Notes
Verify the specific suffix configuration against official datasheets to ensure compatibility with required tolerance and packaging standards. Confirm RoHS compliance status as indicated in manufacturer documentation. Check for regional sales restrictions or distribution limitations before finalizing procurement plans. Ensure ordering quantities align with factory minimums and reel specifications.
Selection Notes
Select this component when a precise 3.3 V reference is needed with tight tolerance requirements. Consider the 500 mW power rating and thermal management capabilities for the intended operating environment. Evaluate the axial leaded package constraints against available board space. Compare performance metrics such as impedance and leakage against alternative regulators if stricter specifications are required.
Part Context
This part belongs to the 1N5518 series of Zener diodes manufactured by Microchip Technology. It is commonly used in electronic circuits requiring reliable voltage stabilization. The device is part of a broader family of discrete semiconductor products focused on diode and rectifier solutions.
Replacement Considerations
Cross-reference with other manufacturers' 1N5518 equivalents to verify pinout and electrical parameter compatibility. Ensure that any substitute part meets the same voltage, power, and package requirements.
