PDTC143ZEF,115

Overview

The PDTC143ZEF,115 is an NPN resistor-equipped transistor from the PDTC143Z series manufactured by Nexperia. It integrates a single NPN transistor with built-in bias resistors R1 (4.7 kΩ) and R2 (47 kΩ). 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 SOT490 (SC-89) plastic surface-mounted package with three leads. The component operates within an ambient temperature range of -65 °C to +150 °C and has a maximum power dissipation of 250 mW at 25 °C.

Feature Summary

• Integrates bias resistors to simplify circuit design
• Reduces overall component count
• Enables reduced pick and place costs

Applications

• General purpose switching and amplification
• Inverter and interface circuits

Procurement Notes

Verify the manufacturer designation as Philips Semiconductors or Nexperia based on production date, as the datasheet originates from 2004. Confirm the specific SOT490 package variant matches the SC-89 footprint requirements for the intended PCB layout. Ensure compliance with absolute maximum ratings regarding thermal resistance and junction temperature limits during operation.

Selection Notes

Select this component when a compact NPN solution with integrated base and emitter biasing is required. The fixed resistor ratio of approximately 10:1 suits standard logic interfacing applications. Verify that the 250 mW power dissipation capability in the SOT490 package meets the thermal requirements of the target environment.
