1N4737A,133

Overview

The Nexperia 1N4737A,133 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It features a nominal working voltage of 7.5 V with a tolerance of ±5%. The device has 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 test current of 34 mA, a differential resistance of 4 Ω, and a reverse current of 0.5 µA at the test current.

Feature Summary

• Hermetically sealed small glass package construction
• Low voltage regulation capability
• Axial leaded configuration for through-hole mounting

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 specifications. Confirm RoHS compliance status and environmental declarations via the manufacturer's product database before finalizing procurement orders.

Selection Notes

Select this component for designs requiring precise low-voltage regulation within the DO-41 form factor. Ensure the circuit design accommodates the specified thermal resistance and power dissipation limits to maintain reliable operation across the full industrial temperature range.

Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series provides nominal working voltages ranging from 3.3 V to 24 V, all utilizing the same hermetically sealed glass package technology for consistent mechanical and electrical performance profiles.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4737A variants that meet the same DO-41 package and 7.5 V specification requirements.
