Overview
The Microchip Technology 1N4752A-1/TR is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 33 V with a tolerance of ±1%. The device operates in the DO-35 axial leaded package and supports through-hole mounting. It provides a maximum power dissipation of 500 mW at ambient temperatures up to +150 °C. The component exhibits a low reverse leakage current of 5 µA and maintains a dynamic impedance of 60 Ω under specified test conditions.
Feature Summary
- Provides stable voltage regulation with tight ±1% tolerance
- Supports high-temperature operation up to +150 °C
- Features low reverse leakage current for efficiency
Applications
- Precision voltage reference circuits
- Overvoltage protection stages
- Voltage regulator designs
Procurement Notes
Verify the specific suffix '-1' against official Microchip documentation to confirm if it denotes a tighter tolerance or specific testing standard compared to the standard 'A' variant. Ensure the DO-35 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when precise voltage regulation is required alongside high thermal stability. The DO-35 package is suitable for general-purpose through-hole assembly. Verify that the 500 mW power rating aligns with the expected operating current and ambient temperature conditions in the target application design.
Part Context
This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. These components are widely used in electronic circuits requiring reliable voltage clamping and regulation. The 1N4752A variant specifically targets the 33 V market segment, offering consistent performance across industrial and commercial environments.
Replacement Considerations
Cross-reference with other manufacturers' 1N4752A equivalents. Verify pinout compatibility and ensure that alternative parts meet the same ±1% tolerance and 500 mW power dissipation specifications.
