1N4753A_T50R

Overview

The onsemi 1N4753A_T50R is a silicon planar Zener diode in the 1N4728A-1N4758A series, housed in a DO-41 through-hole package. It provides a nominal Zener voltage of 36 V with a ±5% tolerance at a test current of 7 mA. The device supports a maximum power dissipation of 1.0 W and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum Zener impedance of 50 Ω at the test current and a maximum reverse leakage current of 5 µA at 27.4 V.

Feature Summary

• Utilizes glass passivated junction construction for enhanced reliability
• Features a molded plastic case with UL94V-0 flame retardant epoxy
• Includes built-in strain relief for mechanical stability
• Guaranteed high-temperature soldering capability at terminals

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify the specific T50R suffix against official documentation to confirm reel packaging requirements. Confirm RoHS compliance status as it may vary by manufacturing date or region. Validate that the requested quantity aligns with standard reel sizes. Ensure storage conditions meet moisture sensitivity level specifications prior to assembly.

Selection Notes

Select this component when a stable 36 V reference is required in through-hole designs. The DO-41 package offers robust thermal performance for 1 W dissipation applications. Consider the 50 Ω impedance for dynamic load variations. Verify lead compatibility with existing PCB layouts before finalizing the design.

Part Context

This part belongs to the widely used 1N47xx series of one-watt Zener diodes manufactured by onsemi. The series covers a broad voltage range from 3.3 V to 100 V. The 1N4753A variant specifically targets the 36 V segment, providing a standard reference point for industrial and consumer electronics requiring precise voltage clamping.

Replacement Considerations

Cross-reference with other manufacturers' 1N4753A equivalents such as Microchip or Taiwan Semiconductor parts. Ensure replacement devices match the DO-41 package dimensions and 1 W power rating. Verify that the replacement's Zener impedance and leakage current specifications meet the original circuit requirements.
