1N4750AP-TP

Overview

The 1N4750AP-TP is a single silicon Zener diode manufactured by Micro Commercial Components (MCC). It provides a nominal Zener voltage of 27 V with a power dissipation rating of 1 W. The device features a ±5% voltage tolerance and operates within a temperature range of -65°C to +200°C junction temperature. Key electrical parameters include a maximum reverse leakage current of 5 µA at 20.6 V, a forward voltage of 1.2 V at 200 mA, and a Zener impedance of 35 Ohms. It is housed in the DO-41G axial through-hole package.

Feature Summary

• Provides stable voltage regulation for circuits requiring a 27 V reference.
• Capable of handling high thermal loads with an extended operating temperature range up to 200°C.
• Constructed with hermetic sealing for reliable performance in harsh environments.

Applications

• Voltage regulation in power supply circuits.
• Overvoltage protection for sensitive electronic components.
• Reference voltage generation in measurement instrumentation.

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm that the specific suffix matches required regulatory compliance standards such as RoHS or REACH. Ensure procurement channels provide traceability documentation. Validate that the DO-41G package dimensions fit the target PCB footprint. Check for any recent product change notices affecting specifications.

Selection Notes

Select this component when a precise 27 V regulation point is required with high thermal stability. The 1 W power rating supports moderate current applications without excessive heat sinking. The wide temperature range makes it suitable for industrial or automotive environments where standard commercial parts may fail. Compare Zener impedance values against noise sensitivity requirements.

Part Context

This part belongs to the 1N4750 series of Zener diodes from MCC. It shares the same fundamental electrical characteristics as other manufacturers' 1N4750A variants but utilizes the specific DO-41G packaging format defined by MCC. The series is designed for general-purpose voltage regulation tasks.

Replacement Considerations

Direct substitutes include the 1N4750A from onsemi and the 1N4750AGE3 from Microchip Technology. Verify pinout compatibility and ensure the replacement package meets mechanical constraints. Cross-reference datasheets for minor variations in leakage current or impedance.
