1N4743AP-TP

Overview

The 1N4743AP-TP is a single Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 13 V with a tolerance of ±5%. The device has a maximum power dissipation of 1 W and operates in the through-hole DO-41 axial package. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 9.9 V, a forward voltage of 1.2 V at 200 mA, and a Zener impedance of 10 Ohms. It is designed for a junction temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation with a 13 V nominal Zener potential.
• Supports high thermal endurance up to a 150°C junction temperature.
• Utilizes a standard DO-41 axial leaded package for through-hole mounting.

Applications

• Voltage reference circuits requiring precise 13 V levels.
• Overvoltage protection stages in electronic systems.
• General-purpose clipping and clamping applications.

Procurement Notes

Verify component authenticity via MCC documentation or authorized distributors. Confirm RoHS compliance status as specified in official datasheets. Check for end-of-life notifications or product change notices prior to procurement. Ensure packaging format matches design requirements.

Selection Notes

Select this component for designs requiring a 13 V Zener voltage with 1 W power handling. The DO-41 package suits through-hole PCB layouts. Verify that the 10 Ohm impedance and 5 µA leakage meet circuit sensitivity requirements. Consider thermal management for continuous operation near maximum ratings.

Part Context

This part belongs to the 1N4743 series of Zener diodes from Micro Commercial Components. It shares specifications with industry-standard 1N4743A devices but carries the specific TP suffix indicating MCC manufacturing. The component is categorized under discrete semiconductor diodes within the broader rectifier and protection market.

Replacement Considerations

Compatible substitutes include 1N4743A-T50A from onsemi and 1N4743ATR from onsemi. These alternatives offer identical 13 V, 1 W, and DO-41 specifications. Verify pinout compatibility and thermal characteristics before substitution.
