PDTC115EU,115

Overview

The PDTC115EU,115 is an NPN resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. It integrates a single NPN transistor with built-in bias resistors R1 and R2, both typically rated at 100 kΩ, within a SOT323 (SC-70) surface-mount package. The device features a maximum collector-emitter voltage (VCEO) of 50 V and a DC output current capability of 20 mA. Key electrical characteristics include a peak collector current of 100 mA, a total power dissipation of 200 mW at 25 °C, and a junction temperature limit of 150 °C. The component operates across an ambient temperature range from -65 °C to +150 °C.

Feature Summary

• Integrates bias resistors directly into the package to reduce external component count
• Simplifies circuit design for digital switching applications
• Reduces pick and place manufacturing costs

Applications

• General purpose switching and amplification
• Inverter and interface circuits
• Circuit driver

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the exact manufacturing origin and tape-and-reel specifications. Ensure that the requested quantity aligns with standard packaging configurations provided by authorized distributors. Cross-reference the manufacturer part number with internal bill-of-materials to prevent substitution errors during procurement.

Selection Notes

Select this component when a compact NPN switching solution with integrated base biasing is required. The 100 kΩ input resistance suits moderate drive currents. Verify that the 20 mA continuous current rating meets load requirements. Consider the SOT323 footprint constraints and thermal dissipation limits relative to the PCB copper area available for heat spreading.

Part Context

This device belongs to the PDTC115E series of NPN resistor-equipped transistors. It serves as the NPN counterpart to the PDTA115EU PNP variant. The series offers various package options including SOT23, SOT416, and SOT883, providing flexibility for different board space and mounting requirements while maintaining consistent electrical performance across the family.

Replacement Considerations

Direct functional substitutes within the same series include other packages of the PDTC115E line such as PDTC115ET or PDTC115EM, provided the pinout matches the target application. For cross-package replacements, verify that the alternative RET maintains the 100 kΩ resistor ratio and 50 V voltage rating.
