PDTA144TE,115

Overview

The PDTA144TE,115 is a PNP resistor-equipped transistor from the PDTA144T series manufactured by Nexperia. It integrates a single bias resistor (R1) with a value of 47 kΩ, while the second resistor (R2) remains open. The device operates in a SOT416 (SC-75) plastic surface-mounted package with three leads. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -50 V and a DC output current (IO) of -100 mA. Total power dissipation is limited to 150 mW at an ambient temperature of 25 °C. The junction temperature rating extends up to 150 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Reduces pick and place costs associated with discrete resistor assembly.

Applications

• General purpose switching and amplification
• Inverter and interface circuits
• Circuit driver

Procurement Notes

Verify that the ordering suffix ,115 corresponds to the specific tape-and-reel packaging configuration defined by the manufacturer for the PDTA144TE part number. Confirm the active status of the component through official Nexperia channels, as business transfers may affect availability. Ensure the selected package variant matches the required PCB footprint specifications for the SOT416 outline.

Selection Notes

Select this component when a compact PNP solution with integrated base biasing is required. The SOT416 package offers a small form factor suitable for space-constrained designs. Verify that the 47 kΩ internal resistor value aligns with the target drive current requirements. Consider the 150 mW power dissipation limit relative to the expected operating conditions and thermal management capabilities of the host system.

Part Context

This component belongs to the PDTA144T series of PNP resistor-equipped transistors. The series includes multiple package options such as SOT23, SOT323, and TO-92 variants. All members share the same core electrical characteristics and internal resistor configuration, differing primarily in physical dimensions and mounting style to accommodate various manufacturing processes.

Replacement Considerations

Direct functional substitutes within the same series include PDTA144TK, PDTA144TM, and PDTA144TS. These alternatives offer identical electrical performance but utilize different package types like SOT346 or SOT883. Cross-package replacement requires verifying mechanical fit and pinout compatibility on the printed circuit board.
