Features

  • PNP with built-in 1k base resistor
  • Eliminates external bias resistor
  • Logic-level drive from MCU
  • SOT-363 ultra-compact
  • RoHS compliant

Applications

  • High-side load driver
  • PNP switching for power gating
  • Relay driver
  • LED driver with PNP switch

The PDTB113ZU from NXP is a PNP digital transistor with integrated 1k base resistor (R1) in SOT-363. The built-in resistor allows direct MCU GPIO drive without external bias components. -50V/-300mA rating suits high-side load switching and power gating applications. PNP configuration enables switching loads connected to ground.

The PNP BJT with integrated R1 (1k) between input and base. When input is pulled low (logic 0), base current flows: IB = (VCC – Vin – VEB) / R1. This turns on the PNP, allowing current flow from emitter to collector. When input is high, no base current flows and the transistor is off.
