1N4745A_R2_00001

Overview

The Panjit International Inc. 1N4745A_R2_00001 is a silicon Zener diode belonging to the 1N47xxA series, designed for voltage regulation applications. It features a nominal Zener voltage of 16 V with a tolerance range of 15.2 V to 16.8 V at a test current of 15.5 mA. The device provides a maximum steady-state power dissipation of 1 W and exhibits a maximum dynamic impedance of 16 Ω. Encased in a molded plastic DO-41 package with axial leads, it supports an operating temperature range from -55°C to +150°C.

Feature Summary

• Utilizes a UL 94V-O rated flame retardant epoxy within a molded plastic DO-41 case.
• Features axial terminals that are solderable per MIL-STD-750 Method 2026.
• Complies with EU RoHS 2.0 standards for lead-free manufacturing.

Applications

• Voltage regulation circuits
• Surge protection devices
• Clamping circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packing details, as variations exist between bulk boxes, ammo boxes, and reels. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors before procurement. Ensure the component lot number is recorded for tracking purposes if quality issues arise during integration.

Selection Notes

Select this component when a 16 V reference voltage with 1 W power handling capability is required in an axial through-hole configuration. Evaluate the thermal resistance characteristics relative to the expected ambient temperature and lead length to ensure adequate heat dissipation. Consider the dynamic impedance specifications for applications requiring stable voltage performance under varying current conditions.

Part Context

This part belongs to the 1N47xxA series manufactured by Panjit International Inc., which covers a wide range of Zener voltages from 3.3 V to 68 V. The series is characterized by its glass passivated junction and hermetically sealed construction options, providing reliable performance in standard electronic equipment applications.

Replacement Considerations

Cross-reference with other manufacturers' 1N4745A equivalents, such as those from onsemi or Microchip Technology, ensuring identical voltage ratings, power dissipation limits, and package dimensions are maintained for direct substitution.
