1N4742A,133

Overview

The Nexperia 1N4742A,133 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 12 V with a tolerance series 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 test current of 21 mA, a differential resistance of 9 Ω, and a reverse current of 0.25 µA.

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 details. Confirm RoHS compliance status and product lifecycle stage before finalizing procurement plans. Ensure the selected variant matches the required voltage tolerance and thermal specifications for the intended circuit design.

Selection Notes

Select this component for applications requiring precise low-voltage regulation within a through-hole axial leaded package. Consider the ±5% voltage tolerance and 1 W power dissipation limits when designing the biasing network. Verify that the operating environment remains within the specified thermal boundaries to ensure long-term reliability.

Part Context

This part belongs to the 1N4728A to 1N4749A series of silicon 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 SOD66 (DO-41) hermetically sealed glass package format.

Replacement Considerations

Direct substitutes include equivalent Zener diodes from other manufacturers such as onsemi or Microchip Technology, provided they match the 12 V nominal voltage, 1 W power rating, DO-41 package, and ±5% tolerance specifications.
