1N4733A-T50A

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.

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.

Applications

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

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.

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.

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.

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.
