PDTA124TT,215

Overview

The PDTA124TT,215 is a PNP resistor-equipped transistor manufactured by Nexperia in the SOT-23 (TO-236AB) surface-mount package. It integrates a single internal bias resistor with a value of 22 kΩ, while the second resistor position remains open. The device supports a maximum collector-emitter voltage of -50 V and a continuous DC output current of -100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at an IC of -1 mA, a collector-emitter saturation voltage of -150 mV at -10 mA, and a thermal resistance from junction to ambient of 500 K/W. The component operates within an ambient temperature range of -65 °C to +150 °C.

Feature Summary

• Integrates a built-in 22 kΩ bias resistor to simplify circuit design and reduce component count.
• Optimized for reduced pick-and-place costs through compact SOT-23 packaging.
• Designed for general-purpose switching and amplification applications.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Confirm that the SOT-23 package variant matches the required PCB footprint dimensions. Ensure the selected distributor provides traceable supply chain data consistent with Nexperia's product authenticity standards.

Selection Notes

Select this component when a PNP configuration with a fixed 22 kΩ base input resistor is required. Verify that the -50 V collector-emitter voltage rating meets the circuit's peak operating conditions. Consider the 22 kΩ resistance value relative to the driving source impedance to ensure adequate base current for saturation.

Part Context

This part belongs to the PDTA124T series of PNP resistor-equipped transistors. The series includes multiple package options such as SOT323, SOT346, and SOT883. The 'TT' suffix specifically identifies the SOT-23 plastic surface-mounted package variant containing three leads.

Replacement Considerations

Compatible substitutes within the same series include PDTC124TT, which serves as the NPN complement. Other packages in the PDTA124T family offer identical electrical specifications but require different PCB footprints.
