1N4753A-T

Overview

The Diodes Incorporated 1N4753A-T is a glass-passivated junction silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 36V with a standard tolerance of ±5%. The device operates within a power dissipation range up to 1.0W at 25°C, derating linearly above this temperature. Key electrical characteristics include a maximum Zener impedance of 50Ω and a reverse leakage current not exceeding 5µA at 27.4V. It utilizes the DO-41 axial leaded package.

Feature Summary

• Glass passivated junction construction for enhanced stability
• Standard 5% Zener voltage tolerance
• Lead-free finish compliant with RoHS directives

Applications

• Voltage regulation circuits
• Reference voltage sources
• Surge protection devices

Procurement Notes

Verify the specific ordering suffix '-T' corresponds to the Tape & Reel packaging configuration as defined in the manufacturer's documentation. Confirm that the component meets the required environmental standards and that the glass encapsulation aligns with the thermal management requirements of the target application design.

Selection Notes

Select this component when a 36V reference point is required in through-hole designs. Consider the 1.0W power rating and the thermal resistance characteristics relative to the ambient operating conditions. Ensure the circuit design accommodates the specified impedance and leakage parameters for precise regulation needs.

Part Context

This part belongs to the 1N4728A through 1N4761A series of 1.0W Zener diodes manufactured by Diodes Incorporated. The series covers a wide voltage range from 3.3V to 75V, providing standardized options for various voltage regulation tasks. The 'A' designation indicates the standard 5% tolerance variant.

Replacement Considerations

Datasheet explicitly recommends using DFLZxx series for new designs instead of this legacy component.
