1N4743A,113

Overview

The Nexperia 1N4743A,113 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 13 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 test current of 19 mA, a differential resistance of 10 Ω, and a reverse current of 0.25 µA.

Feature Summary

• Hermetically sealed small glass package for reliable operation
• Low voltage stabilization capability
• Wide operating temperature range

Applications

• Low voltage stabilizers

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging configuration. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure the selected variant matches the required axial leaded package dimensions for your PCB layout constraints.

Selection Notes

Select this component when a stable 13 V reference is required in high-density circuit designs. The DO-41 package facilitates through-hole mounting. Evaluate thermal resistance requirements based on ambient conditions and expected load currents to ensure safe operation within the specified power dissipation limits.

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 package format. This standardization simplifies inventory management for designs requiring multiple voltage levels.

Replacement Considerations

Direct replacements include other manufacturers' 1N4743A variants that meet the same 13 V, 1 W, and DO-41 specifications. Verify pinout orientation and thermal characteristics before substitution.
