PDTC114ET,235

Overview

The PDTC114ET is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia, housed in a small 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 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 is nominally 10 kΩ with a range of 7 to 13 kΩ, while the feedback resistor R2 is also 10 kΩ. The device features a DC current gain of 30 minimum at 5 mA collector current and a transition frequency of 230 MHz typical.

• Cost-saving alternative for BC847 series in digital applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify that the specific part number matches the required non-automotive qualification status, as this product data sheet indicates the device is not automotive qualified unless explicitly stated otherwise. Confirm the ordering suffix corresponds to the desired packaging format, such as the 235 variant associated with standard reel packing. Ensure compatibility with the specified SOT23 footprint dimensions during PCB layout to guarantee proper soldering and thermal performance.

Selection Notes

Select the PDTC114ET when a compact NPN transistor solution with integrated biasing is required for space-constrained designs. This component serves as a direct replacement for discrete resistor-transistor networks, reducing pick-and-place costs. Engineers should verify that the 50 V collector-emitter voltage rating meets the maximum operating voltage of the target application circuit before finalizing the design.

Part Context

This component belongs to the NPN Resistor-Equipped Transistor family from Nexperia, designed for digital logic interfacing. The PNP complement for this specific configuration is the PDTA114ET. Both devices share similar physical characteristics and are intended for applications requiring simplified biasing networks in low-power digital circuits.

Replacement Considerations

The PDTC114ET can replace discrete resistor-transistor combinations or other NPN RETs with matching pinouts and electrical ratings. Verify that substitute components maintain the same SOT23 package outline and bias resistor values to ensure circuit compatibility without redesign.

FAQ

What is the function of the internal resistors in the PDTC114ET?

The PDTC114ET includes two built-in bias resistors: R1 (input/base) and R2 (emitter/base). These resistors simplify circuit design by eliminating the need for external discrete resistors, thereby reducing component count and assembly costs.

Is the PDTC114ET suitable for automotive applications?

No, the PDTC114ET is not automotive qualified. The product data sheet explicitly states that this specific product is not suitable for automotive use unless it is designated with an automotive qualification suffix. Customers must use products specifically qualified for automotive environments.

What is the marking code for the PDTC114ET?

The marking code for the PDTC114ET is '%16', where '%' represents a placeholder for the manufacturing site code. This code is printed on the SOT23 package for identification purposes.
