1N4738A,113

Overview

The Nexperia 1N4738A,113 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 8.2 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 4.5 Ω, and a reverse current of 0.5 µA at the test current.

Feature Summary

• Hermetically sealed small glass package construction
• 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 configuration. Confirm RoHS compliance status and environmental declarations prior to integration. Ensure the selected variant matches the required axial leaded form factor for the intended circuit layout.

Selection Notes

Select this component for applications requiring precise low-voltage regulation within the specified power dissipation limits. Consider the thermal resistance from junction to tie-point when designing heat management strategies. Verify that the required working current falls within the safe operating area defined by the datasheet limiting values.

Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series offers a broad selection of nominal working voltages ranging 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 other manufacturers' 1N4738A variants. Verify pinout compatibility and ensure equivalent electrical parameters such as Zener voltage tolerance and power rating are met before substitution.
