PDTA115TE,115

Overview

The PDTA115TE,115 is a PNP resistor-equipped transistor from the PDTA115T series, manufactured by Nexperia (formerly NXP Standard Product business). It integrates a single bias resistor (R1) with an internal value of 100 kΩ, while the second resistor (R2) remains open. The device is housed in the SOT416 (SC-75) plastic surface-mounted package with three leads. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V and a DC output current (IO) of -100 mA. The component operates within an ambient temperature range of -65 °C to +150 °C and features a total power dissipation of 150 mW at 25 °C.

Feature Summary

• Integrates a built-in input bias resistor to reduce external component count
• Simplifies circuit design and reduces pick-and-place manufacturing costs
• Available in multiple surface-mounted and through-hole package variants

Applications

• General purpose switching and amplification circuits
• Circuit drivers requiring integrated biasing
• Inverter and interface logic circuits

Procurement Notes

Verify the ordering suffix matches the required packaging format. The -115 suffix indicates availability in tape and reel configurations for automated assembly. Confirm the specific revision status against the latest datasheet issued by Nexperia, as product data sheets may undergo updates reflecting changes in company naming or legal definitions without altering technical content.

Selection Notes

Select the PDTA115TE variant when the SOT416 (SC-75) surface-mount footprint is required for the design. Ensure the circuit design accounts for the fixed 100 kΩ internal bias resistor value, which falls within a tolerance range of 70 kΩ to 130 kΩ. Verify that the maximum collector-emitter voltage and current ratings align with the operational stress limits of the target application environment.

Part Context

This component belongs to the PDTA115T series of PNP resistor-equipped transistors. The series includes complementary NPN types such as the PDTC115TE. While originally associated with NXP Semiconductors, the standard product business was transferred to Nexperia B.V. in February 2017. All technical documentation now references Nexperia, though legacy part numbers remain valid identifiers for the same semiconductor devices.

Replacement Considerations

Direct functional substitutes within the same series include the PDTA115TK (SOT346), PDTA115TM (SOT883), and PDTA115TT (SOT23). These alternatives offer identical electrical characteristics but utilize different physical packages. Designers must verify pinout compatibility and thermal resistance differences before substituting the SOT416 package with other form factors.
