Overview
The PDTA123YU,115 is a PNP Resistor-Equipped Transistor (RET) manufactured by Nexperia in the SOT323 (SC-70) surface-mount package. It integrates a single PNP transistor with built-in bias resistors: R1 (input) has a typical value of 2.2 kΩ, and the R2/R1 ratio is typically 4.5. The device supports a 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 at 25 °C ambient temperature. The junction temperature maximum is 150 °C, with an operating range from -65 °C to +150 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Reduces pick and place costs associated with discrete resistor placement.
Applications
- General purpose switching and amplification
- Circuit drivers
- Inverter and interface circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official packing information table to confirm the tape and reel pitch and quantity. Ensure the package version matches the required footprint for the PCB layout. Confirm that the marking code corresponds to the intended manufacturing origin as specified in the datasheet.
Selection Notes
Select this component when a compact PNP solution with integrated biasing is required for space-constrained designs. The SOT323 package offers a small footprint suitable for high-density boards. Verify that the 2.2 kΩ input resistance aligns with the driving source impedance requirements for the intended logic levels.
Part Context
This part belongs to the PDTA123Y series of PNP resistor-equipped transistors. The 'U' suffix denotes the SOT323 (SC-70) plastic surface-mounted package variant. Other series members include variants in SOT23, SOT883, and through-hole packages, all sharing the same internal resistor values but differing in physical dimensions and thermal characteristics.
Replacement Considerations
PDTC123YU is the NPN complement within the same series. For direct pin-compatible substitution in PNP applications, verify thermal resistance differences if using other SOT323 RETs. Cross-reference with PDTC123YU only if converting polarity is acceptable.
