1N4735A-TP

Overview

The MCC 1N4735A-TP is a silicon planar Zener diode with a nominal voltage of 6.2 V and a 5% tolerance, housed in a DO-41 glass package. It features a maximum power dissipation of 1.0 W at 50°C, derating by 10 mW/°C above this temperature. The device operates within a junction temperature range of -65°C to +200°C and has a thermal resistance of 100 K/W. Electrical characteristics include a maximum reverse leakage current of 10 µA at 3 V, a test current of 41 mA, and a dynamic impedance of 2 Ω.

Feature Summary

• Hermetic glass package construction for environmental stability
• Silicon planar technology ensuring consistent electrical performance
• Lead-free finish compliant with RoHS directives

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection applications

Procurement Notes

Verify the authenticity of the component through authorized distributors or direct manufacturer channels to avoid counterfeit parts. Confirm that the ordering suffix matches the required packaging format, such as tape and reel or bulk. Ensure compliance with specific project requirements regarding moisture sensitivity levels and lead-free exemptions before finalizing procurement decisions.

Selection Notes

Select this component when a stable 6.2 V reference is needed in through-hole designs. The DO-41 package provides robust mechanical support for high-power dissipation up to 1.0 W. Consider the low dynamic impedance for applications requiring precise voltage clamping. Verify that the operating temperature range aligns with the intended environmental conditions of the target system.

Part Context

This part belongs to the 1N47 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. The 'A' suffix indicates a 5% voltage tolerance, distinguishing it from standard versions with 10% tolerance. The '-TP' suffix designates the specific packaging configuration offered by the manufacturer.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4735A variants in the DO-41 package. Ensure replacement parts maintain the same 6.2 V nominal voltage, 1.0 W power rating, and 5% tolerance. Verify that alternative components meet the same hermetic sealing and thermal resistance specifications.
