1N4732A,133

Overview

The Nexperia 1N4732A,133 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 4.7 V with a tolerance series of ±5%. The device supports a total power dissipation of up to 1000 mW and operates within a junction temperature range of -65 °C to +200 °C. Key electrical characteristics include a maximum forward voltage of 1.2 V at 200 mA, a differential resistance of 8 Ω, and a reverse current of 500 µA.

Feature Summary

• Hermetically sealed small glass package for reliable operation
• Low voltage stabilizer functionality
• Wide operating temperature range

Applications

• Low voltage stabilizers

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Confirm RoHS compliance status and ensure the component matches the required hermetically sealed glass package variant before finalizing procurement orders.

Selection Notes

Select this component when a precise 4.7 V reference is needed in axial leaded designs. Ensure the circuit can accommodate the specified 1 W power dissipation limit and that the ±5% voltage tolerance aligns with system requirements. Verify thermal management capabilities for the intended ambient conditions.

Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series offers various nominal working voltages ranging from 3.3 V to 24 V, all utilizing the same SOD66 (DO-41) package format for consistent mechanical integration across different voltage regulation needs.

Replacement Considerations

Direct replacements include other manufacturers' equivalents adhering to the standard 1N4732A specification. Verify that substitute components maintain the same DO-41 footprint, 4.7 V nominal voltage, and ±5% tolerance to ensure compatibility.
