1N4749A,113

Overview

The Nexperia 1N4749A,113 is a voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 24 V with a tolerance of ±5%. 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 test current of 10.5 mA, a differential resistance of 25 Ω, and a maximum reverse current of 5 μA at the specified working voltage.

Feature Summary

• Hermetically sealed small glass package construction
• Wide operating junction temperature range up to 200 °C
• Standardized ±5% voltage tolerance series

Applications

• Low voltage stabilizers

Procurement Notes

Verify the specific part number suffix against official Nexperia documentation to confirm exact packaging configuration and compliance status. Ensure that the required thermal management aligns with the absolute maximum ratings defined in the product data sheet. Confirm availability through authorized distribution channels as manufacturing schedules may vary.

Selection Notes

Select this component for circuits requiring a stable 24 V reference or regulation point. The DO-41 axial leaded package facilitates through-hole mounting on printed circuit boards. Consider the 1000 mW power dissipation limit when designing heat dissipation paths for continuous operation at elevated ambient temperatures.

Part Context

This component belongs to the 1N4728A to 1N4749A series manufactured by Nexperia. The series comprises 22 types covering nominal working voltages from 3.3 V to 24 V. All devices in this family share the same hermetically sealed SOD66 glass package and general structural specifications.

Replacement Considerations

Direct substitutes include the generic 1N4749A designation found across various semiconductor manufacturers. Verify pinout compatibility and ensure equivalent voltage and power ratings before implementation.
