1N4749A,133

Overview

The Nexperia 1N4749A,133 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 forward voltage of 1.2 V at 200 mA, a differential resistance of 25 Ω, and a reverse current of 5 µA at 18.2 V.

Feature Summary

• Hermetically sealed small glass package for reliable operation
• Nominal working voltage range from 3.3 V to 24 V across the series
• Tolerance series available with ±5% accuracy

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 configuration. Confirm RoHS compliance status and REACH registration requirements prior to procurement. Ensure the requested quantity aligns with manufacturer standard packing quantities to avoid partial reel handling issues during assembly.

Selection Notes

Select this component when a stable 24 V reference is required in through-hole designs. Verify that the thermal resistance and power dissipation limits accommodate the circuit's operating conditions. Ensure the package dimensions fit the PCB layout constraints. Check compatibility with existing manufacturing processes for axial leaded components.

Part Context

This part belongs to the 1N4728A to 1N4749A series of low voltage regulator diodes manufactured by Nexperia USA Inc. The series offers various nominal voltages from 3.3 V to 24 V in a standardized DO-41 package. These devices are designed for general-purpose voltage regulation applications requiring high reliability and consistent performance.

Replacement Considerations

Direct substitutes include parts from other manufacturers with identical specifications, such as the 1N4749A from onsemi. Verify pinout compatibility and electrical parameters before substitution.
