1N4730A,113

Overview

The Nexperia USA Inc. 1N4730A,113 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package with axial leads. It features a nominal working voltage of 3.9 V and a total power dissipation of 1000 mW. The device maintains a tolerance series of ±5% 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 9 Ω, and a reverse current of 400 µA at 1 V.

Feature Summary

• Hermetically sealed small glass package construction
• Low voltage stabilizer functionality
• Wide operating temperature range capability

Applications

• Low voltage stabilizers

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration, as variations exist for tape and reel or cut tape formats. Confirm RoHS compliance status and REACH registration details directly with the manufacturer prior to finalizing procurement orders to ensure regulatory adherence for the intended market.

Selection Notes

Select this component when a precise 3.9 V reference is required in through-hole designs. Ensure the circuit design accommodates the specified differential resistance and test current conditions. Verify that the thermal management strategy supports the 1000 mW power dissipation limit under expected ambient conditions.

Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series offers nominal working voltages ranging from 3.3 V to 24 V. All variants share the same SOD66 package form factor and general electrical profile, differing primarily in their specific Zener voltage ratings.

Replacement Considerations

Cross-reference with other manufacturers' 1N4730A equivalents. Verify pinout compatibility and thermal resistance values before substitution.
