Overview
The Nexperia USA Inc. 1N4747A,133 is a low voltage regulator diode housed in a hermetically sealed SOD66 (DO-41) glass package. It provides a nominal working voltage of 20 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 test current of 12.5 mA, a differential resistance of 22 Ω, and a maximum reverse current of 750 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 such as Ammo Pack or Bulk quantities. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the selected variant matches the required axial leaded configuration for the intended through-hole mounting process.
Selection Notes
Select this component for circuits requiring precise 20 V regulation with tight tolerance requirements. The DO-41 package offers robust mechanical stability for high-density designs. Evaluate thermal resistance parameters to ensure adequate heat dissipation under continuous load conditions within the specified ambient temperature limits.
Part Context
This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series covers nominal working voltages from 3.3 V to 24 V. All variants share the same hermetically sealed glass package form factor and general structural specifications defined in the product data sheet.
Replacement Considerations
Direct substitutes include equivalent Zener diodes from other manufacturers offering identical 20 V nominal voltage, 1 W power rating, and DO-41 axial package dimensions. Verify pinout orientation and cathode marking band alignment before substitution.
