1N4751AP-TP

Overview

The MCC 1N4751AP-TP is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 30 V with a tolerance of ±5%. The device has a maximum power dissipation of 1 W and operates in the through-hole DO-41 axial package. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 22.8 V, a forward voltage of 1.2 V at 200 mA, and a maximum Zener impedance of 40 Ohms. It supports a junction temperature range from -65°C to 150°C.

Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon junction.
• Encapsulated in a hermetically sealed glass DO-41 axial package for durability.
• Capable of handling a continuous power dissipation of 1 Watt.

Applications

• General-purpose voltage reference circuits
• Overvoltage protection stages
• Power supply output regulation

Procurement Notes

Verify the specific manufacturer part number against official Micro Commercial Components documentation to confirm exact electrical tolerances and package dimensions. Ensure compliance with RoHS and REACH requirements as specified in the latest datasheet before procurement. Confirm availability status directly with authorized distributors or the manufacturer.

Selection Notes

Select this component when a standard 30 V regulation point is required within a 1 W power budget. The DO-41 through-hole package facilitates manual assembly and prototyping. Verify that the operating environment remains within the specified -65°C to 150°C junction temperature limits to ensure long-term reliability.

Part Context

This component belongs to the 1N4751 series of Zener diodes manufactured by Micro Commercial Components. It serves as a standardized replacement for legacy JEDEC 1N4751 specifications. The 'TP' suffix typically denotes tape and reel packaging options available from the manufacturer.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4751A specification. Ensure substitute parts match the 30 V nominal voltage, 1 W power rating, and DO-41 package footprint. Verify equivalent Zener impedance and leakage current parameters for circuit compatibility.
