1N4761AP-TP

Overview

The MCC 1N4761AP-TP is a 1.0 W silicon Zener diode housed in the DO-41 axial package. It provides a nominal Zener voltage of 75 V with a ±5% tolerance, tested at a current of 3.3 mA. The device features a maximum dynamic impedance of 175 Ω and a maximum reverse leakage current of 5 µA at 56 V. It operates within a junction temperature range of -65°C to +150°C and includes built-in strain relief for mechanical stability.

Feature Summary

• Glass passivated construction for enhanced reliability
• Built-in strain relief integrated into the molded glass axial leads
• Epoxy material meets UL 94 V-0 flammability rating
• Lead-free finish compliant with RoHS standards

Applications

• Voltage regulation circuits requiring stable reference levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm that the ordering suffix matches the required packaging format, such as Tape & Reel or Ammo Packing, as specified in the manufacturer's documentation before finalizing orders.

Selection Notes

Select this component when a precise 75 V reference is needed in through-hole designs. Ensure the circuit can accommodate the 175 Ω dynamic impedance and verify that the operating environment stays within the specified thermal limits. Derate current by 20% if driving capacitive loads to maintain performance integrity.

Part Context

This part belongs to the 1N4736AP through 1N4764AP series, covering Zener voltages from 6.8 V to 100 V. All devices in this family share the same 1.0 W power dissipation rating and DO-41 package dimensions, allowing for standardized board layouts across different voltage requirements.

Replacement Considerations

Cross-reference with other manufacturers offering standard 1N4761A specifications in the DO-41 package. Verify that substitute parts match the 75 V nominal voltage, 1.0 W power rating, and 175 Ω maximum impedance to ensure functional compatibility.

FAQ

What is the maximum surge current rating for the 1N4761AP-TP?

The maximum surge current (IZM) rating for the 1N4761AP-TP is 60 mA.

Does the 'P' suffix indicate a specific electrical characteristic change?

No, the 'P' suffix designates that the component has a lead-free finish and is RoHS compliant; it does not alter the electrical parameters.
