1N4753A-T50A

Overview

The onsemi 1N4753A-T50A is a single Zener diode designed for through-hole mounting in the DO-41-2 axial package. It provides a nominal Zener voltage of 33 V with a 5% tolerance and a maximum power dissipation of 1 W. The device operates within a temperature range of -65°C to +200°C, featuring 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 Zener breakdown characteristics
• Capable of handling high thermal loads up to 200°C junction temperature
• Offers precise voltage tolerance for reliable circuit performance

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in power supplies
• Clamping applications in signal conditioning paths

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and date codes against official onsemi documentation. Ensure the DO-41-2 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the specific datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a 33 V regulation point is required in high-temperature environments. The 1 W power rating supports moderate current loads, while the low leakage current ensures minimal standby power consumption. Verify that the 45 Ohm impedance meets the dynamic regulation needs of your specific application design.

Part Context

This component belongs to the standard 1N47xx series of axial leaded Zener diodes manufactured by onsemi. The series is widely utilized in general-purpose electronics for basic voltage regulation tasks. The T50A suffix typically denotes specific packaging or tape-and-reel configurations within the product line.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4753A variants in the DO-41 package. Ensure replacement parts maintain the same 33 V nominal voltage, 1 W power rating, and 5% tolerance to guarantee electrical compatibility without redesigning the surrounding circuitry.
