1N4756AP-TP

Overview

The MCC 1N4756AP-TP is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 47 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within a temperature range of -65°C to +150°C junction temperature. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 35.8 V, a forward voltage of 1.2 V at 200 mA, and a maximum Zener impedance of 80 Ohms. It utilizes the DO-41 axial through-hole package.

Feature Summary

• Provides stable voltage regulation with a nominal 47 V Zener breakdown.
• Features low reverse leakage current for efficient standby operation.
• Constructed in a hermetically sealed glass DO-41 package for durability.

Applications

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

Procurement Notes

Verify the specific suffix AP-TP against the manufacturer's latest datasheet to confirm packaging configuration and compliance status. Ensure the procurement channel sources genuine Micro Commercial Components products to avoid counterfeit components. Cross-reference the Mouser part number 833-1N4756AP-TP or DigiKey identifier 353-1N4756AP-TPTR-ND for accurate identification during sourcing.

Selection Notes

Select this component when a standard 47 V regulation point is required in through-hole designs. The DO-41 package suits automated insertion or manual assembly processes. Consider the 80 Ohm impedance limit for load regulation requirements. Verify thermal management capabilities given the 1 W power rating and operating temperature limits.

Part Context

This component belongs to the 1N4756 series of Zener diodes manufactured by Micro Commercial Components. It shares the fundamental electrical specifications with industry-standard equivalents but is distinguished by its specific manufacturing origin and packaging variants. The AP-TP designation indicates a specific reel or tape-and-reel configuration offered by the manufacturer.

Replacement Considerations

Direct substitutes include the 1N4756A from onsemi and Taiwan Semiconductor, which share identical 47 V, 1 W, and DO-41 specifications. Vishay's 1N4756A-TR offers similar parameters but may differ in power rating details. Verify pinout compatibility and thermal characteristics before substitution.
