1N4755A-TP

Overview

The MCC 1N4755A-TP is a silicon planar Zener diode housed in a hermetically sealed DO-41 glass package. It provides a nominal voltage of 43 V with a 5% tolerance and a maximum power dissipation of 1.0 W at 25°C ambient temperature. The device features a low forward voltage drop of 1.2 V at 200 mA and a maximum reverse leakage current of 5 µA at 32.7 V. Its dynamic impedance is specified at 70 Ohms, and it operates within a temperature range of -65°C to +200°C.

Feature Summary

• Hermetic glass compression bonded construction for environmental protection
• Silicon planar technology ensuring stable voltage regulation
• Lead-free finish compliant with RoHS directives

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Power supply regulation

Procurement Notes

Verify the authenticity of the component by checking for official Micro Commercial Components markings and authorized distributor traceability. Confirm that the ordering suffix matches the required packaging format, as variations exist between tape-and-reel and bulk configurations. Ensure compliance with specific project requirements regarding moisture sensitivity levels and lead exemptions before finalizing procurement.

Selection Notes

Select this component when a precise 43 V regulation point is required in through-hole designs. The DO-41G package accommodates standard axial mounting techniques. Consider the thermal resistance characteristics and derating factors if operating above 50°C ambient temperatures. Verify that the 5% voltage tolerance aligns with the circuit's precision requirements compared to other available tolerance options.

Part Context

This part belongs to the 1N47xx series of 1.0 Watt Zener diodes manufactured by Micro Commercial Components. The 'A' suffix indicates a 5% voltage tolerance, distinguishing it from standard (10%) or tighter (2%) variants. The '-TP' suffix designates a lead-free, RoHS-compliant version packaged in tape-and-reel format for automated assembly processes.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4755A specification in the DO-41 package. Ensure equivalent thermal resistance and hermetic sealing capabilities are maintained. Verify that substitute components meet the same 5% voltage tolerance and 1.0 W power dissipation ratings.
