1N4750A-T

Overview

The Vishay General Semiconductor - Diodes Division 1N4750A-T is a single silicon Zener diode designed for through-hole mounting in the DO-41 package. It provides a nominal Zener voltage of 27 V with a standard tolerance of 5%. The component supports a power dissipation of 1 W and operates within a temperature range from -65 °C to +200 °C. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 35 Ohms, and a test current of 9.5 mA.

Feature Summary

• Glass passivated die construction for enhanced environmental stability
• High power dissipation capability of 1 Watt
• Low inductance design suitable for high-frequency applications
• Standardized 5% voltage tolerance for consistent performance

Applications

• Voltage regulation in DC power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement instruments
• Clamping circuits in signal processing systems

Procurement Notes

Verify the specific manufacturer designation as sources may attribute this part number to Rectron or other distributors. Confirm the package type is DO-41 and the power rating is 1W. Ensure the voltage tolerance matches the required 5% specification. Check RoHS compliance status if restricted substances are a constraint. Validate the operating temperature range against your application requirements before finalizing procurement.

Selection Notes

Select this component when a reliable 27 V reference is needed in a through-hole design. The DO-41 package offers robust mechanical stability for industrial environments. Consider the 1 W power rating for thermal management needs. The low leakage current ensures minimal impact on high-impedance circuits. Verify compatibility with existing PCB footprints and assembly processes.

Part Context

This device belongs to the widely used 1N47xxA series of Zener diodes, known for their reliability and standardized specifications. The 'T' suffix typically indicates tape and reel packaging, facilitating automated assembly. As a silicon-based component, it offers predictable breakdown characteristics across a wide temperature range, making it a staple in general-purpose electronics design.

Replacement Considerations

Direct substitutes include the 1N4750A from onsemi or Taiwan Semiconductor, which share identical electrical parameters and DO-41 packaging. Other manufacturers like Won-Top Electronics offer equivalent parts such as the 1N4750A-T3-LF. Ensure any replacement maintains the 27 V nominal voltage, 5% tolerance, and 1 W power dissipation rating.
