1N4732A-T50A

Overview

The onsemi 1N4732A-T50A is a single-channel general-purpose Zener diode with a nominal voltage of 4.7 V and a maximum power dissipation of 1 W. It features a 5% voltage tolerance and is housed in a DO-41 through-hole package. The device operates within a temperature range of -65°C to +200°C, with a maximum reverse leakage current of 10 µA at 1 V and a Zener impedance of 8 Ω.

Feature Summary

• Provides stable voltage regulation with a nominal 4.7 V output.
• Supports high-temperature operation up to 200°C.
• Features low reverse leakage current for efficient performance.

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipper and clamper circuits

Procurement Notes

Verify the specific suffix T50A against official datasheets to confirm packaging or marking variations. Confirm component availability status as distribution channels may list obsolete or discontinued stock. Ensure compliance with RoHS and REACH requirements for the intended market. Validate lead times directly with authorized distributors.

Selection Notes

Select this component for applications requiring a 4.7 V reference in a standard axial leaded package. Consider the 1 W power rating and 5% tolerance for precision requirements. Evaluate thermal derating curves if operating near the maximum temperature limit. Compare impedance values against circuit sensitivity needs.

Part Context

This part belongs to the 1N47 series of silicon Zener diodes manufactured by onsemi. These components are widely used in industrial and consumer electronics for basic voltage regulation tasks. The DO-41 package provides robust mechanical stability for through-hole mounting processes.

Replacement Considerations

Compatible substitutes include Nexperia 1N4732A and TC 1N4732ATA. Verify pinout compatibility and electrical parameter equivalence before substitution.
