Overview
The Microchip Technology 1N5527/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 7.5 V with a test current of 1 mA. The device operates within a power dissipation limit of 500 mW and maintains a maximum reverse leakage current of 500 nA at 6.8 V. Electrical characteristics include a Zener impedance of 35 Ohms and a forward voltage of 1.1 V at 200 mA. The component supports an operating temperature range from -65°C to +175°C junction temperature and utilizes the DO-204AH (DO-35) axial through-hole package.
Feature Summary
- Provides stable voltage regulation with a nominal 7.5 V breakdown characteristic
- Supports high-temperature operation up to 175°C junction temperature
- Utilizes a standard axial leaded package for through-hole mounting
Applications
- Voltage reference circuits requiring precise regulation
- Overvoltage protection in electronic systems
- General-purpose voltage regulator designs
Procurement Notes
Verify the specific suffix designation, as official documentation lists variants such as 1N5527C/TR, 1N5527B/TR, and 1N5527D/TR. Confirm the exact tolerance and packaging configuration required for the application. Ensure compatibility with the DO-204AH footprint and validate thermal management requirements for the specified power dissipation limits during procurement.
Selection Notes
Select this component when a 7.5 V Zener voltage is required with a 500 mW power rating. Consider the 35 Ohm impedance and 500 nA leakage specifications for circuit sensitivity. The wide temperature range makes it suitable for demanding environments. Verify that the through-hole package aligns with the board layout and assembly process constraints.
Part Context
This part belongs to the Microchip Technology Zener Diodes category under Diodes & Rectifiers. It is manufactured by Microchip Technology and falls within the single Zener diode subcategory. The component is available in bulk or tape-and-reel formats depending on the specific suffix variant selected.
Replacement Considerations
Verified parameter-equivalent substitutes include 1N5527C/TR, 1N5527B/TR, and 1N5527D/TR. These alternatives share the same manufacturer and core electrical specifications but may differ in tolerance or packaging format.
