PDTA144WT,215

Overview

The PDTA144WT,215 is a PNP resistor-equipped transistor from the PDTA144W series manufactured by Nexperia. It integrates bias resistors R1 and R2 within a single SOT-23 (TO-236AB) package to simplify circuit design. The device features a collector-emitter voltage (VCEO) of -50 V and a continuous DC output current (IO) of -100 mA. Typical internal resistance values are 47 kΩ for R1 and 22 kΩ for R2. Total power dissipation is rated at 250 mW at an ambient temperature of 25 °C. The junction temperature maximum is 150 °C, with an operating ambient range of -65 °C to +150 °C.

Feature Summary

• Built-in bias resistors reduce component count and pick-and-place costs
• Simplified circuit design through integrated pre-biasing
• Single surface-mount package containing both transistor and resistors

Applications

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

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when a compact PNP solution with fixed biasing is required. The SOT-23 package suits space-constrained designs. Ensure input voltage limits do not exceed +10 V or -40 V depending on polarity. Confirm thermal requirements align with the 250 mW dissipation rating in the target application environment.

Part Context

This part belongs to the PDTA144W series of PNP resistor-equipped transistors. It serves as the complement to the PDTC144WT NPN variant. The series offers various package options including SOT883, SOT323, and TO-92, but the WT suffix specifically denotes the SOT-23 plastic surface-mounted package configuration.

Replacement Considerations

The PDTC144WT is the NPN complement within the same series. For direct PNP replacement, verify pinout compatibility with other PDTA144W variants in SOT-23 if available. No other specific substitute part numbers are documented in the provided source material.
