DRA9144W0L

Overview

The DRA9144W0L is a PNP digital transistor manufactured by Panasonic Electronic Components. It integrates a single bipolar junction transistor with a built-in bias resistor network within a compact SSMini3-F2-B surface-mount package measuring 1.2x1.2mm. The device features a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) rating of -100 mA. A typical input resistance of 47 kΩ is provided, establishing a bias resistor ratio of approximately 4.7. This configuration simplifies circuit design by reducing component count and board space requirements while maintaining stable switching performance.

Feature Summary

• Integrates a PNP transistor with a built-in bias resistor to minimize external components
• Compact SSMini3-F2-B package size of 1.2x1.2mm for high-density mounting
• Designed for efficient signal switching and level translation applications

Applications

• General-purpose signal switching in consumer electronics
• Level shifting between different logic voltage domains
• Driver circuits for low-power loads in embedded systems

Procurement Notes

Verify the specific suffix W0L against the manufacturer's latest datasheet to confirm pinout orientation and electrical tolerances. Ensure compliance with RoHS directives if required by the target market. Cross-reference the part number with authorized distributors to confirm current availability status, as discontinuation notices may apply to older revisions.

Selection Notes

Select this component when a compact PNP switch with integrated biasing is required. The 47 kΩ input resistor suits moderate drive currents. Verify that the -50 V rating exceeds the maximum circuit voltage. Consider thermal dissipation limits within the small package for high-frequency switching duties.

Part Context

This part belongs to Panasonic's DRA series of digital transistors, which combine BJTs with internal resistors. The SSMini3-F2-B package is a standard small-outline form factor used across various semiconductor manufacturers for space-constrained designs. The DRA9144 variant specifically denotes the PNP polarity and 47 kΩ resistor value.
