1N4733A-T50A

Single Zener Diodes Overview

The onsemi 1N4733A-T50A is a silicon planar power Zener diode designed for voltage regulation and clipping applications. It features a nominal Zener voltage of 5.1 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W at 25°C and operates within a temperature range of -65°C to +200°C junction temperature. Packaged in the DO-41 axial leaded format, it exhibits a typical Zener impedance of 9 Ohms and a maximum reverse leakage current of 50 uA.

Single Zener Diodes Feature Summary

• Provides stable voltage reference capabilities through precise Zener breakdown characteristics.
• Engineered for high thermal stability with an extended operating temperature range up to 200°C.
• Utilizes a robust glass encapsulated DO-41 package suitable for through-hole mounting.

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable DC references.
• Overvoltage protection and transient suppression in electronic systems.
• Waveform clipping and limiting applications in signal processing.

Single Zener Diodes Procurement Notes

Verify the specific suffix T50A against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with RoHS and REACH requirements as indicated in the manufacturer's documentation. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V regulation point is required with ±5% precision. Consider the 1 W power rating and DO-41 package size for board space constraints. Evaluate the 9 Ohm impedance for dynamic load performance needs. Confirm that the 200°C junction temperature rating aligns with the thermal environment of the target application.

Single Zener Diodes Part Context

This device belongs to the industry-standard 1N47xxA series of Zener diodes. The 'A' suffix typically denotes a tighter voltage tolerance compared to non-suffixed variants. The T50A suffix indicates specific packaging or handling configurations provided by onsemi for automated assembly processes.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the Vishay 1N4733A and Panasonic ERZ-E05V511. Verify that replacement parts match the 5.1 V nominal voltage, 1 W power rating, and DO-41 package dimensions. Ensure equivalent electrical parameters such as Zener impedance and leakage current are met for circuit functionality.
