Overview
The PDTC114EK,135 is an NPN resistor-equipped transistor (RET) manufactured by NXP USA Inc. It integrates a single NPN silicon small-signal transistor with built-in bias resistors in a SC-59A (SOT-323) plastic surface-mount package. The device features a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Internal resistance values are specified as R1 = 10 kΩ connected to the base and R2 = 10 kΩ connected between the base and emitter. This configuration simplifies circuit design by reducing component count and pick-and-place costs while maintaining general-purpose switching and amplification capabilities.
Feature Summary
- Integrates NPN transistor with dual bias resistors for simplified circuit topology
- Reduces printed circuit board space and assembly complexity through component consolidation
- Provides standardized electrical characteristics for general-purpose signal processing
Applications
- General purpose switching circuits
- Amplification stages in low-power applications
- Inverter and interface logic circuits
- Digital circuit driver applications
Procurement Notes
Verify the complete part number including the suffix to ensure correct packaging specifications. Confirm that the SC-59A package dimensions align with the target footprint. Ensure the internal resistor tolerances meet the specific circuit requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN switch with fixed biasing is required. The 10 kΩ resistor values are suitable for standard logic levels. Consider thermal dissipation limits if operating near maximum current ratings. Verify compatibility with existing PCB silkscreen and assembly processes for the SOT-323 package.
Part Context
This component belongs to the PDTC series of resistor-equipped transistors from NXP. These devices replace discrete transistor and resistor combinations. The SC-59A package offers a small footprint compared to traditional through-hole alternatives. It is designed for high-volume consumer and industrial electronics manufacturing.
Replacement Considerations
Direct substitutes include other NPN RETs with identical 10k/10k resistor ratios and SC-59A packaging. Verify pinout compatibility and electrical ratings match exactly. Cross-reference with Nexperia PDTA or PDTA series equivalents if sourcing flexibility is required.
