1N4761A-TP

Overview

The MCC 1N4761A-TP is a silicon planar Zener diode housed in a hermetic DO-41 glass package. It provides a nominal Zener voltage of 75 V with a ±5% tolerance, as indicated by the 'A' suffix. The device dissipates up to 1.0 W at 25°C ambient temperature and operates within a junction temperature range of -65°C to +200°C. Electrical characteristics include a maximum reverse leakage current of 5 µA at 56 V, a dynamic impedance of 175 Ω at the test current of 3.3 mA, and a forward voltage drop of 1.2 V at 200 mA.

Feature Summary

• Hermetic glass construction for environmental stability
• Silicon planar technology for reliable voltage regulation
• Built-in strain relief on axial leads

Applications

• DC power supply voltage regulation
• Voltage reference circuits
• Overvoltage protection stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging type and compliance status. The '-TP' designation indicates tape and reel packaging. Confirm RoHS compliance and lead-free finish requirements with the authorized distributor or manufacturer prior to procurement to ensure alignment with project specifications.

Selection Notes

Select this component when a precise 75 V regulation point is required with tight tolerance. The DO-41 package supports through-hole mounting and high thermal resistance derating. Ensure the application accounts for the positive temperature coefficient inherent to Zener voltages above approximately 5 V.

Part Context

This part belongs to the 1N4728 through 1N4761 series of 1 Watt Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.3 V to 75 V. The 'A' suffix specifically denotes a 5% voltage tolerance, distinguishing it from standard (10%) or tighter (2%) variants within the same family.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4761A specification in a DO-41 package. Verify that substitute parts match the 75 V nominal voltage, 1 W power rating, and 175 Ω dynamic impedance to maintain circuit performance.
