Overview
The PDTC144ET,215 is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia in a SOT23 surface-mounted device plastic package. It integrates bias resistors to simplify circuit design and reduce component count. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, an output current capability of 100 mA, and a total power dissipation of 250 mW at 25 °C ambient temperature. The built-in input bias resistor (R1) has a typical value of 47 kΩ with a range of 33 to 61 kΩ, while the bias resistor ratio (R2/R1) typically equals 1.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce overall component count.
- Provides 100 mA output current capability suitable for general-purpose switching applications.
- Designed as a cost-saving alternative for BC847 series transistors in digital logic circuits.
Applications
- Digital applications in industrial segments
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for digital switching or interface circuits. Ensure the 50 V collector-emitter voltage and 100 mA continuous current ratings align with the load requirements. Verify that the standard non-automotive qualification meets the application standards, as automotive-grade variants require different part numbers.
Part Context
This component belongs to the PDTC144E family of NPN resistor-equipped transistors. It serves as the NPN counterpart to the PDTA144ET PNP variant. The device is designed for surface-mount assembly, offering a space-efficient alternative to discrete transistor and resistor combinations in modern electronic designs.
Replacement Considerations
The PDTA144ET is the direct PNP complement within the same product family. For automotive applications requiring AEC-Q101 qualification, the PDTC144ET-QR is the designated qualified substitute. Other generic NPN RETs may require schematic adjustments due to differing internal resistor values.
