1N4742A,113

Overview

The Nexperia 1N4742A,113 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 12 V with a ±5% tolerance. The device supports a maximum total power dissipation of 1000 mW and operates within a junction temperature range of -65 °C to +200 °C. Key electrical characteristics include a forward voltage of 1.2 V at 200 mA, a differential resistance of 9 Ω, and a reverse current of 0.25 µA at 5 V.

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 details. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm that the SOD66 axial leaded package dimensions align with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a stable 12 V reference is required in through-hole designs. The DO-41 package offers robust mechanical stability compared to surface-mount alternatives. Consider the thermal resistance characteristics if high ambient temperatures are expected in the application environment.

Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series covers nominal voltages from 3.3 V to 24 V, all utilizing the same hermetically sealed glass package format. This standardization simplifies inventory management for designs requiring multiple voltage levels.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4742A variants. Verify pinout compatibility and thermal performance when replacing with equivalent parts from different suppliers.
