1N4744AP-TP

Overview

The 1N4744AP-TP is a single Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 15 V with a tolerance of ±5%. The device has a maximum power dissipation of 1 W and operates in through-hole DO-41 packages. Key electrical parameters include a maximum reverse leakage current of 5 µA, a Zener impedance of 14 Ohms, and a test current of 17 mA. It supports a Zener current of 61 mA and functions within an operating temperature range from -65 °C to +150 °C.

Feature Summary

• Provides stable voltage regulation via the Zener breakdown effect for circuit protection and reference applications.
• Constructed with silicon planar technology housed in a hermetically sealed glass axial leaded package.
• Designed for high thermal stability and reliable performance across a wide industrial temperature range.

Applications

• Voltage regulation in DC power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm compliance with RoHS and REACH standards. Ensure the procurement channel provides valid traceability documentation. Confirm that the received components match the DO-41 package dimensions and marking codes specified in the official product specifications before integration into production lines.

Selection Notes

Select this component when a precise 15 V regulation point is required with low leakage characteristics. The 1 W power rating allows for moderate current handling in through-hole designs. Verify that the system's thermal environment remains within the specified -65 °C to +150 °C junction temperature limits to ensure long-term reliability and consistent voltage regulation performance.

Part Context

This part belongs to the standard 1N47xx series of 1 Watt Zener diodes produced by MCC. It utilizes the widely adopted DO-41 axial glass package, facilitating easy insertion into printed circuit boards. The 'AP' designation typically indicates specific tolerance and testing criteria defined by the manufacturer for this particular voltage bin within the broader family of voltage regulator diodes.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4744A equivalents in the DO-41 package. Verify that substitute parts meet the identical 15 V Zener voltage, 1 W power dissipation, and ±5% tolerance requirements. Ensure the replacement component maintains compatible thermal and electrical characteristics for direct pin-to-pin substitution.
