PDTA124EMB,315

Overview

The PDTA124EMB,315 is a PNP digital transistor from Nexperia, integrated with a single base resistor in an SOT-363 surface-mount package. It features a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an internal base resistor of 47 kΩ, providing a DC current gain (hFE) of at least 100 at IC = -10 mA. Operating temperatures range from -55 °C to +150 °C, with a total power dissipation of 330 mW. This component is designed for switching applications requiring high input impedance and simplified circuit layouts.

Feature Summary

• Integrated base resistor eliminates external components, reducing board space and assembly complexity.
• High DC current gain ensures reliable switching performance with low drive currents.
• Compact SOT-363 package facilitates high-density PCB designs.

Applications

• General-purpose switching in consumer electronics
• Level shifting and logic interface circuits
• Driver stages for LEDs and small loads

Procurement Notes

Verify the complete part number including the suffix '315' to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance and specific manufacturing date codes against project requirements. Cross-reference with official Nexperia distributors to validate authenticity and supply chain integrity before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP switch with built-in biasing is required. Ensure the application voltage does not exceed -50 V and current stays within -100 mA limits. Consider thermal constraints given the 330 mW power dissipation in the SOT-363 package. Verify that the 47 kΩ internal resistor matches the desired base drive characteristics for the target load.

Part Context

This part belongs to Nexperia's PDTA series of pre-biased transistors, which integrate resistors directly onto the silicon die or within the package. The SOT-363 variant offers a three-terminal solution replacing discrete transistor-resistor combinations. It is widely used in portable devices where space conservation and simplified bill of materials are critical design factors.

Replacement Considerations

Direct substitutes include other PDTA124 variants from different manufacturers with identical pinout and electrical specifications. Verify equivalent hFE ranges and resistor tolerance values. Alternative packages like SC-88 may require schematic adaptation due to pin reassignment.
