PDTD114EU135

Overview

The PDTD114EU135 is an NPN Resistor-Equipped Transistor (RET) from the PDTD1xxxU series, manufactured by Nexperia. It integrates a single NPN transistor with built-in bias resistors R1 and R2 in a SOT-323 (SC-70) surface-mount package. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a continuous output current (IO) of 500 mA, and a typical DC current gain (hFE) of 70 at IC = 50 mA. The internal resistors are typically 10 kΩ each (R1 input, R2 base-emitter), with a resistor ratio tolerance of ±10%. The device supports junction temperatures up to 175 °C and is AEC-Q101 qualified for automotive applications.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• AEC-Q101 qualified for automotive reliability requirements
• Supports high temperature applications up to 175 °C junction temperature
• Provides cost-saving alternative to discrete BC807 or BC817 series transistors

Applications

• Controlling IC inputs
• Switching loads
• Digital applications requiring space reduction

Procurement Notes

Verify the specific ordering suffix '135' against official Nexperia documentation to confirm reel specifications or tape-and-reel dimensions. Ensure the source document explicitly links this suffix to the PDTD114EU part number before procurement. Confirm RoHS compliance status through the manufacturer's latest product data sheet.

Selection Notes

Select this component when a compact NPN switching solution with integrated biasing is required. The 10 kΩ resistor values suit standard logic interface levels. Consider the 500 mA current capability and 50 V voltage rating for load driving tasks. Verify thermal management requirements given the small SOT-323 package size and power dissipation limits.

Part Context

This part belongs to the PDTD1xxxU family of NPN resistor-equipped transistors. It serves as the NPN complement to the PDTB114EU PNP variant. The series shares common packaging and qualification standards, offering designers a standardized option for digital interface and driver circuits across various Nexperia product lines.

Replacement Considerations

The direct PNP complement is PDTB114EU. For discrete replacements, consider BC817 series transistors with external bias resistors, though this increases board space. Verify pinout compatibility and electrical ratings when substituting with other RET families.
