Overview
The PDTC143TS,126 is an NPN resistor-equipped transistor (RET) from the PDTC143T series. It integrates a single bias resistor (R1 = 4.7 kΩ) with R2 left open. The device features a collector-emitter voltage (VCEO) of 50 V and a DC output current (IO) of 100 mA. It is housed in a SOT54 plastic single-ended leaded through-hole package. Key electrical characteristics include a maximum total power dissipation of 500 mW at 25 °C and a thermal resistance from junction to ambient of 250 K/W.
Feature Summary
- Built-in bias resistors simplify circuit design by reducing component count and pick-and-place costs.
Applications
- General purpose switching
- Amplification circuits
- Inverter and interface circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest product data sheet to confirm package type and manufacturing origin. Ensure compatibility with the required through-hole mounting method for the SOT54 package. Confirm that the integrated resistor configuration matches the intended circuit requirements before finalizing procurement.
Selection Notes
Select this component when a compact NPN transistor with a fixed base bias resistor is needed for general-purpose applications. The SOT54 through-hole package is suitable for designs requiring manual assembly or specific mechanical constraints. Verify that the 4.7 kΩ internal resistor value aligns with the target drive current and logic levels.
Part Context
This part belongs to the PDTC143T series of NPN resistor-equipped transistors. The series includes various packages such as SOT23, SOT323, and SOT883. The PDTC143TS specifically utilizes the SOT54 (TO-92) package, distinguishing it from the surface-mount variants within the same functional family.
Replacement Considerations
The PNP complement PDTA143TS may be used if a complementary polarity is required. Other members of the PDTC143T series offer different packages but share identical electrical characteristics and resistor values.
