Overview
The PDTC114TK,115 is an NPN Resistor-Equipped Transistor (RET) from the PDTC114T series manufactured by Nexperia. It integrates a single bias resistor R1 of 10 kΩ with the emitter resistor left open. The device features a collector-emitter voltage rating of 50 V and supports an output current capability of 100 mA. It is housed in the SOT346 package, which corresponds to the SC-59A and TO-236JEDEC standards. The component is designed for digital applications, offering a cost-saving alternative to discrete transistor-resistor combinations.
Feature Summary
- Integrates a built-in 10 kΩ input bias resistor to simplify circuit design
- Reduces printed-circuit board space and pick-and-place manufacturing costs
- Provides high DC current gain suitable for switching loads
Applications
- Controlling IC inputs
- Switching loads
- Digital logic interface circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging details and regional availability. Confirm that the SOT346 package variant matches the required footprint for the target assembly process. Ensure compliance with RoHS directives as specified in the product data sheet before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN switching solution with integrated base biasing is required. The fixed 10 kΩ internal resistor eliminates external components, reducing bill-of-materials complexity. Verify that the 50 V collector-emitter voltage and 100 mA current ratings exceed the maximum operational requirements of the specific application circuit.
Part Context
This part belongs to the PDTC114T family of NPN resistor-equipped transistors. The TK designation specifically identifies the SOT346 surface-mount package. Other variants in the series include TE (SOT416), TM (SOT883), TS (SOT54), TT (SOT23), and TU (SOT323). All variants share identical electrical characteristics but differ in physical package dimensions and pin configurations.
Replacement Considerations
Direct replacements within the same family include PDTC114TE, PDTC114TM, PDTC114TS, PDTC114TT, and PDTC114TU. These parts offer identical electrical performance but utilize different packages such as SOT416, SOT883, SOT54, SOT23, or SOT323. Cross-package substitution requires verifying mechanical fit and pinout compatibility.
