1N4744A,133

Overview

The Nexperia 1N4744A,133 is a voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 15 V with a tolerance 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 differential resistance of 14 Ω, and a reverse current of 5 µA at 11.4 V.

Feature Summary

• Hermetically sealed small glass package for reliable operation
• Wide operating voltage range covering low voltage stabilization needs
• High junction temperature capability for demanding environments

Applications

• Low voltage stabilizers

• Over-voltage protection

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging configuration. Confirm RoHS compliance status and environmental declarations 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 15 V reference is required in through-hole designs. Consider the thermal resistance from junction to tie-point for heat management. Evaluate the differential resistance and test current requirements against your circuit's load conditions to ensure accurate regulation performance.
