Overview
The 1N4731AT9-E is a single Zener diode manufactured by Renesas Electronics Corporation. It belongs to the 1N4728A through 1N4753A series, designed for constant voltage applications. The component functions as a rectifier diode in specific contexts but is primarily classified as a single Zener diode within discrete semiconductor products. It supports supply voltage stabilization, reference voltage detection, and surge absorption tasks.
Feature Summary
- Provides stable reference voltage for detection circuits
- Absorbs electrical surges to protect downstream components
- Stabilizes supply voltages in small power supplies
Applications
- Supply voltage stabilization in small power supplies
- Reference voltage detection circuits
- Surge absorption protection
Procurement Notes
Verify the manufacturer designation, as sources list both Hitech Semiconductor Co., Limited and Renesas Electronics America Inc. Confirm RoHS compliance status, which is documented as lead-free and compliant. Ensure the package type matches project requirements, with EXA (PDIP-8) dimensions noted in available data. Cross-reference the part number against the official 1N4728A-1N4753A datasheet for accurate electrical specifications.
Selection Notes
Select this component when a standard Zener voltage reference is required for low-power stabilization or surge protection. It is suitable for designs needing reliable voltage clamping without complex regulation circuitry. Verify that the thermal and current ratings of the 1N4731AT9-E align with the specific load conditions of the target application before integration.
Part Context
This device is part of the broader 1N4728A through 1N4753A series published by Renesas Electronics. These diodes are categorized under discrete semiconductors, specifically single Zener diodes. The series is engineered for general-purpose voltage regulation and protection roles in electronic systems requiring stable DC references.
Replacement Considerations
Compatible substitutes include other parts from the 1N4728A through 1N4753A series. Verify pinout compatibility and exact Zener voltage tolerance before substitution. Ensure the replacement maintains the same package style and RoHS compliance status.
