DRA9143T0L

Overview

The DRA9143T0L is a PNP digital transistor manufactured by Panasonic Electronic Components, designed for switching applications. It features a built-in bias resistor with a ratio of 2. The device is housed in an SSMini3 F3 B surface-mount package, measuring 1.6 x 0.85 x 0.6 mm. Key electrical specifications include a maximum collector-emitter voltage (Vce) of 50 V and a maximum collector current (Ic) of 100 mA. The minimum DC current gain (hFE) is specified at 160. It operates within a temperature range from -55 °C to +150 °C and has a typical input resistance of 10 kΩ.

Feature Summary

• Integrated bias resistor network simplifies circuit design by reducing component count.
• High thermal stability supports operation up to +150 °C junction temperature.
• Compact SSMini3 package facilitates high-density PCB mounting.

Applications

• General-purpose signal switching
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix T0L against official Panasonic datasheets to confirm pinout and internal resistor configuration. Ensure the ordering code matches the required SSMini3 F3 B package variant. Cross-reference RoHS compliance status with the latest manufacturer documentation before procurement.

Selection Notes

Select this component when a compact PNP digital transistor with a 2:1 bias resistor ratio is required. Verify that the 50 V Vce rating and 100 mA Ic limit meet the target circuit requirements. Consider the 10 kΩ input resistance for base drive calculations. Confirm compatibility with the intended operating temperature range.

Part Context

This part belongs to Panasonic's series of resistor-biased transistors, which integrate NPN or PNP transistors with internal biasing resistors. These devices are engineered to replace discrete transistor-resistor combinations, offering space savings and improved consistency in switching performance compared to manual assembly of individual components.
