1N4751A-TP

Overview

The MCC 1N4751A-TP is a silicon planar Zener diode housed in a hermetic DO-41G glass package. It provides a nominal Zener voltage of 30 V with a ±5% tolerance at a test current of 8.5 mA. The device supports a maximum power dissipation of 1.0 W and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 22.8 V, a dynamic impedance of 40 Ω, and a forward voltage drop of 1.2 V at 200 mA.

Feature Summary

• Hermetic glass encapsulation for environmental protection
• Silicon planar construction for stable regulation
• Lead-free finish compliant with RoHS standards

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify the specific suffix (e.g., -TP) against official distributor catalogs to confirm packaging format and compliance status. Ensure sourcing from authorized channels to guarantee traceability and authenticity, as counterfeit components pose significant risks to circuit reliability.

Selection Notes

Select this component when a precise 30 V reference is required in through-hole designs. The hermetic glass package offers superior stability compared to plastic alternatives. Verify that the thermal resistance and derating curves align with the expected ambient operating conditions.

Part Context

This part belongs to the 1N4728A through 1N4761A series of 1.0 Watt Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.3 V to 75 V, utilizing standardized JEDEC case outlines for broad compatibility across various electronic assemblies.

Replacement Considerations

Equivalent parts include the 1N4751A from other manufacturers such as onsemi or Central Semiconductor, provided they match the 30 V rating, 1 W power dissipation, and DO-41 package dimensions.
