DRA5143T0L

Overview

The DRA5143T0L is a Panasonic PNP resistor-biased transistor with built-in resistance, housed in an SMini3 F2 B surface-mount package. It features a maximum collector-emitter voltage of 50 V and a maximum power dissipation of 150 mW. The device includes a typical input resistance of 4.7 kΩ with a resistance ratio of 1. It has a minimum DC current gain (hFE) of 20 and supports a maximum operating temperature of +150 °C. The component measures 2 x 1.25 x 0.8 mm.

Feature Summary

• Integrated biasing resistor eliminates external components for simplified circuit design.
• High thermal stability supports operation at elevated temperatures up to +150 °C.
• Compact surface-mount footprint enables high-density PCB layouts.

Applications

• Switching applications in consumer electronics
• Driver circuits for small signal loads
• Logic interface buffering

Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to confirm exact electrical tolerances and packaging specifications. Confirm that the requested part number matches the required voltage and current ratings for the target application before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP switching solution with integrated biasing is required. Ensure the 50 V collector-emitter voltage rating exceeds the maximum circuit voltage. Verify that the 150 mW power dissipation capability is sufficient for the intended load conditions and ambient temperature environment.

Part Context

This component belongs to Panasonic's series of resistor-biased transistors designed for space-saving electronic designs. These devices integrate a single transistor with a base resistor, replacing multiple discrete components. The SMini3 package provides a standardized form factor for automated assembly processes in modern manufacturing lines.

Replacement Considerations

Cross-reference with Panasonic part numbers such as DRA5143E0L or DRC5143Z0L for similar NPN/PNP configurations. Verify pinout compatibility and electrical parameters before substituting to ensure circuit functionality remains intact.
