1N4743A_R2_00001

Overview

The Panjit International Inc. 1N4743A_R2_00001 is a silicon Zener diode with a nominal voltage of 13 V and a maximum power dissipation of 1 W. It features a DO-41 molded plastic case with axial leads. The device has a maximum Zener impedance of 10 Ω at a test current of 19 mA and a maximum leakage current of 0.1 µA at 9.9 V. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Plastic package meets UL 94V-O flammability classification
• Terminals are solderable per MIL-STD-750, Method 2026
• Lead-free construction compliant with EU RoHS 2.0

Applications

• Voltage regulation circuits
• Power supply protection
• General-purpose rectification

Procurement Notes

Verify the specific suffix _R2_00001 against official documentation to confirm packing type and marking code. Confirm compliance requirements such as RoHS 2.0 and UL 94V-O ratings match project specifications before ordering.

Selection Notes

Select this component for applications requiring a 13 V reference or regulation point in through-hole designs. Ensure the circuit can handle the 1 W power dissipation and that the operating temperature stays within the specified -55 °C to +150 °C range.

Part Context

This part belongs to the 1N4728A series, which covers nominal Zener voltages from 3.3 V to 68 V. All devices in this series share the same 1 W power rating and DO-41 package style, differing primarily in breakdown voltage and associated impedance values.

Replacement Considerations

Cross-reference with other manufacturers' 1N4743A parts to ensure pinout and electrical parameters align. Verify that alternative sources offer the same DO-41 package and thermal characteristics.
