1N4753A-T

Overview

The 1N4753A-T is a single silicon Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 36 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1.3 W and exhibits a maximum Zener impedance of 1000 Ohms. It operates within a junction temperature range up to 175°C. The component is designed for through-hole mounting in an axial DO-204AL (DO-41) package. It holds AEC-Q101 automotive qualification.

Feature Summary

• Automotive-grade reliability certified under the AEC-Q101 standard
• High thermal stability supporting operation at elevated junction temperatures
• Robust axial leaded construction suitable for through-hole circuit integration

Applications

• Voltage regulation in automotive electronic systems
• Overvoltage protection circuits requiring high thermal endurance
• Reference voltage generation in industrial control modules

Procurement Notes

Verify current production status as this specific suffix variant may be discontinued. Confirm that the required power rating and impedance specifications align with system design constraints. Ensure the DO-41 package dimensions fit the target PCB layout. Validate that the automotive qualification meets project requirements. Check for alternative active versions if supply continuity is critical.

Selection Notes

Select this component when automotive certification and high-temperature performance are mandatory. The 1.3 W rating exceeds standard 1 W equivalents, offering higher surge capability. The DO-41 package provides mechanical robustness for harsh environments. Verify that the 1000 Ohm impedance is acceptable for the application's noise sensitivity. Consider active alternatives like the -TR or -TAP variants if availability is constrained.

Part Context

This part belongs to the 1N4753 series of Zener diodes from Vishay. The series is widely used for voltage reference and protection applications. The specific -T suffix denotes a tape-and-reel packaging format, distinct from bulk or cut-tape options. The series maintains consistent electrical characteristics across different packaging styles while adhering to standardized axial leaded form factors.

Replacement Considerations

Active substitutes include 1N4753A-TR and 1N4753A-TAP from the same manufacturer. These variants share identical electrical parameters but differ in packaging configuration. Cross-manufacturer replacements must match the 36 V Zener voltage, 1.3 W power rating, and DO-41 package footprint.
