1N4730A,133

Overview

The Nexperia 1N4730A,133 is a Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within an extended temperature range from -65°C to +200°C. Packaged in the DO-41 axial through-hole format, it exhibits a maximum Zener impedance of 9 Ohms at a test current of 37 mA. Reverse leakage current is specified at a maximum of 5 µA when tested at 4.7 V.

Feature Summary

• Provides stable voltage regulation with tight tolerance accuracy
• Capable of operation across extreme ambient temperatures up to 200°C
• Utilizes robust axial leaded packaging for reliable through-hole mounting

Applications

• General purpose voltage regulation circuits
• Voltage reference sources in electronic systems
• Over-voltage protection stages

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure the procurement channel provides valid RoHS compliance declarations. Cross-reference the manufacturer part number with authorized distributor databases to confirm authenticity and traceability before finalizing orders.

Selection Notes

Select this component when a 6.8 V regulation point is required in high-power through-hole designs. The wide operating temperature range supports demanding industrial environments. Verify that the circuit load current remains within the safe operating area defined by the 1 W power dissipation limit and thermal constraints of the DO-41 package.

Part Context

This component belongs to the standard 1N47 series of Zener diodes manufactured by Nexperia. The series offers a broad spectrum of voltage ratings and power capabilities. The 1N4730A variant specifically addresses mid-range voltage needs in legacy and modern axial packages, maintaining compatibility with established design architectures requiring reliable voltage clamping.

Replacement Considerations

Direct substitutes include the generic 1N4730A specification from other manufacturers such as onsemi or Vishay. Verify that replacement parts match the 6.8 V nominal voltage, 1 W power rating, and DO-41 package dimensions to ensure mechanical and electrical interchangeability.
