DRA2143X0L

Overview

The DRA2143X0L is a PNP digital transistor manufactured by Panasonic Electronic Components. It features an integrated base resistor with a typical value of 4.7 kΩ and a ratio of 0.47. The device is housed in a Mini3 G3 B surface-mount package, measuring 2.9 x 2.8 mm. Key electrical ratings include a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Maximum power dissipation is rated at 200 mW, with a maximum operating temperature of +150°C.

Feature Summary

• Integrates a built-in base resistor to simplify circuit design and reduce component count.
• Utilizes a compact Mini3 G3 B surface-mount package for efficient PCB space utilization.
• Supports high-temperature operation up to +150°C for robust performance in demanding environments.

Applications

• General-purpose switching applications in consumer electronics.
• Driver circuits for low-power loads requiring pre-bias functionality.
• Signal level shifting and logic interface circuits.

Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to ensure correct internal resistance values and packaging options. Confirm that the Mini3 G3 B package dimensions align with your PCB footprint requirements. Check for any recent product change notifications or end-of-life status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a PNP digital transistor with a 4.7 kΩ base resistor is required. Ensure the -50 V voltage rating and -100 mA current capacity meet the load requirements. Consider the Mini3 G3 B package size constraints and the +150°C thermal limit during the design phase to guarantee reliable operation under all expected conditions.

Part Context

This part belongs to the Panasonic Digital Transistor series, which combines bipolar junction transistors with internal resistors. These devices are designed to replace discrete transistor-resistor combinations, offering improved reliability and reduced assembly time. The DRA2143X0L specifically addresses applications needing PNP switching with predefined biasing characteristics.

Replacement Considerations

Consult official Panasonic cross-reference lists for verified substitutes. Generic equivalents may differ in internal resistance ratios or thermal characteristics. Verify pinout compatibility and package dimensions before substitution to prevent circuit malfunction.
