PDTC124ET,215

Overview

The PDTC124ET,215 is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates a single transistor with built-in bias resistors R1 and R2, both nominally 22 kΩ, into a SOT23 surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous output current of 100 mA. Key electrical characteristics include a minimum DC current gain of 60 at 5 mA, a transition frequency of 230 MHz, and a total power dissipation of 250 mW. The component operates within an ambient temperature range of -65 °C to +150 °C.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• Provides cost-saving alternative for standard small-signal transistors in digital applications
• Reduces pick and place costs through integrated resistor configuration

Applications

• Digital applications in automotive and industrial segments
• Controlling IC inputs
• Switching loads

Selection Notes

Select this component when a compact NPN switching solution with integrated base biasing is required. The fixed 22 kΩ resistor ratio simplifies logic interface design compared to discrete transistor setups. Ensure the application does not require AEC-Q101 automotive qualification; if automotive grade is needed, select the PDTC124ET-QR variant instead.

Part Context

This part belongs to the PDTC124 series of Resistor-Equipped Transistors from Nexperia. It serves as the NPN complement to the PDTA124ET PNP version. The device is designed as a drop-in replacement for BC847 series transistors in digital circuits, offering a smaller footprint and reduced assembly complexity due to the internal integration of biasing components.

Replacement Considerations

The PDTA124ET is the PNP complement. For automotive-qualified versions, consider the PDTC124ET-QR. Discrete BC847 transistors may be used but require external bias resistors.
