Overview
The PDTC143TU,135 is an NPN resistor-equipped transistor (RET) from the PDTC143T series manufactured by Nexperia. It integrates a single bias resistor (R1 = 4.7 kΩ) with an open R2 configuration within a SOT323 (SC-70) plastic surface-mounted package. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous DC output current (IO) of 100 mA. Total power dissipation is rated at 200 mW under standard mounting conditions. The component operates within an ambient temperature range of -65 °C to +150 °C and features a junction temperature limit of 150 °C.
Feature Summary
- Built-in bias resistors simplify circuit design and reduce component count.
- Reduces pick and place costs during manufacturing.
- Single NPN transistor with integrated base resistor.
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver applications
Procurement Notes
Verify the ordering suffix '135' against official Nexperia documentation to confirm specific reel packaging or regional manufacturing origin details. Ensure the requested part matches the SOT323 package variant. Cross-reference the datasheet revision date to confirm technical specifications remain current for your design requirements.
Selection Notes
Select this component when a compact NPN switch with a fixed 4.7 kΩ base resistor is required. The SOT323 package offers a small footprint suitable for space-constrained designs. Verify that the 200 mW power dissipation rating in the SOT323 package meets the thermal requirements of the target application environment.
Part Context
This part belongs to the PDTC143T series of NPN resistor-equipped transistors. The series includes various package options such as SOT23, SOT883, and TO-92. The TU suffix specifically denotes the SOT323 (SC-70) surface-mount package variant with the specified electrical characteristics.
Replacement Considerations
Direct replacements include other PDTC143T series variants like PDTC143TT (SOT23) or PDTC143TM (SOT883) if package changes are acceptable. PNP complements such as PDTA143TU are available for complementary logic designs.
