1N4752A_T50R

Overview

The onsemi 1N4752A_T50R is a single silicon Zener diode with a nominal voltage of 33 V and a maximum power dissipation of 1.0 W at a lead temperature of 50°C. It features a 5% tolerance, a test current of 7.5 mA, and a maximum dynamic impedance of 45 Ω. The device operates within a temperature range of -65°C to +200°C and utilizes a DO-41 axial through-hole package.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features a glass passivated junction for corrosion resistance and reliable performance
• Includes built-in strain relief in the DO-41 package design

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources

Procurement Notes

Verify that the ordering suffix _T50R corresponds to the Ammo Pack packaging format specified by onsemi. Confirm RoHS compliance status directly from the manufacturer's documentation before procurement. Ensure the component meets specific environmental requirements such as REACH standards.

Selection Notes

Select this component when a 33 V reference is required in a standard DO-41 through-hole configuration. Consider the 45 Ω dynamic impedance and 7.5 mA test current for circuit stability. Verify thermal derating requirements above 50°C if ambient temperatures exceed standard conditions.

Part Context

This part belongs to the 1N4728A through 1N4758A series of one-watt Zener diodes manufactured by onsemi. The series covers a wide voltage selection from 3.3 V to 56 V. All devices share identical mechanical dimensions and mounting characteristics within the DO-41 JEDEC registered package.

Replacement Considerations

Equivalent parts include the 1N4752A from other manufacturers. Surface mount equivalents are available as SMBJ4752A or SMAJ4752A.
