1N4750A-TR

Overview

The Vishay General Semiconductor - Diodes Division 1N4750A-TR is a silicon planar power Zener diode designed for voltage stabilization and clipping circuits. It features a nominal Zener voltage of 27 V with a standard tolerance of ± 5 %. The device operates within a test current range of 3.3 to 76 mA, depending on the specific part number in the series. It provides a maximum reverse leakage current of 5 µA at a specified reverse voltage. The component is housed in a DO-41 (DO-204AL) package and supports a peak power dissipation of 1300 mW under transient conditions.

Feature Summary

• Utilizes silicon planar technology for robust performance in high-power stabilizing applications
• Provides precise voltage regulation with a standard Zener voltage tolerance of ± 5 %
• Features low reverse leakage current characteristics suitable for sensitive circuit protection

Procurement Notes

Verify that the ordering code matches the required taped units per reel configuration. Confirm compliance with material categorization standards by referencing the official Vishay documentation. Ensure the selected variant aligns with the specific Zener voltage requirements for your application. Cross-reference the datasheet revision date to confirm the accuracy of electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component based on the required nominal Zener voltage and the specific test current operating point. Consider the thermal resistance and power dissipation limits when designing for continuous operation versus transient surge conditions. Verify that the DO-41 through-hole package dimensions fit the intended PCB layout constraints. Evaluate the dynamic resistance values to ensure adequate regulation performance for the target load current.

Part Context

This component belongs to the 1N4728A to 1N4761A series of silicon planar power Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of nominal Zener voltages from 3.3 V to 75 V. These devices are engineered for use in demanding electronic environments requiring reliable voltage regulation and surge protection capabilities.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4750A variants in the DO-41 package. Ensure replacement parts maintain the same 27 V nominal Zener voltage and ± 5 % tolerance. Verify that alternative components support equivalent power dissipation ratings and meet the required thermal equilibrium specifications.
