1N4752A-T50A

Overview

The onsemi 1N4752A-T50A is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 33 V with a tolerance of ±5%. The device dissipates up to 1 W of power and operates within a temperature range of -65 °C to +200 °C. Packaged in the DO-41-2 axial through-hole format, it exhibits a maximum reverse leakage current of 5 µA and a Zener impedance of 45 Ohms at a test current of 7.5 mA.

Feature Summary

• Provides stable voltage regulation via avalanche breakdown characteristics
• Capable of handling high junction temperatures up to 200 °C
• Utilizes hermetically sealed glass passivation for environmental protection

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications for transient suppression

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number 1N4752A-T50A with official onsemi documentation. Confirm that the specific suffix T50A corresponds to the intended Ammo Pack packaging configuration. Ensure compliance with RoHS and REACH standards as specified in the product datasheet before finalizing procurement orders.

Selection Notes

Select this component when a 33 V regulation point is required within a standard through-hole design. The DO-41 package facilitates manual insertion or standard wave soldering processes. Consider the 1 W power dissipation limit and thermal management requirements for the specific operating environment to ensure reliable long-term performance.

Part Context

This device belongs to the 1N47xxA series of one-watt Zener diodes manufactured by onsemi. The series offers various voltage options within the same physical footprint, allowing designers to maintain consistent board layouts while adjusting circuit parameters. The T50A suffix specifically denotes the Ammo Pack variant for automated assembly.

Replacement Considerations

Equivalent parts include the 1N4752A from Taiwan Semiconductor and Vishay General Semiconductor. Verify that substitute components match the 33 V nominal voltage, 1 W power rating, and DO-41 package dimensions to ensure mechanical and electrical compatibility.
