DRA9143Z0L

Overview

The Panasonic DRA9143Z0L is a PNP digital transistor featuring a built-in bias resistor, housed in the SSMini3 F3 B surface-mount package. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device integrates a typical input resistance of 47 kΩ with a built-in bias resistor ratio of 0.21. Designed for high-temperature environments, it supports a maximum operating temperature of +150 °C and offers a minimum DC current gain (hFE) of 30. This single-transistor configuration occupies a compact footprint of 1.6 x 1.6 mm.

Feature Summary

• Integrated bias resistor network simplifies circuit design by eliminating external base resistors.
• High thermal stability allows reliable operation at junction temperatures up to +150 °C.
• Compact SSMini3 F3 B package enables dense surface-mount PCB layouts.

Applications

• General-purpose switching circuits requiring compact form factors
• Driver stages for low-power loads in consumer electronics
• Logic interface buffers between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix Z0L against official Panasonic documentation to confirm tape-and-reel packaging specifications. Ensure that the ordering information matches the exact electrical characteristics required for the target application, as minor variations may exist across different production batches or regional datasheets.

Selection Notes

Select this component when a PNP digital transistor with a 47 kΩ internal resistor is required. The 50 V rating suits low-voltage logic systems. Consider the 100 mA current limit and 150 °C thermal capability during thermal management planning. Verify compatibility with the SSMini3 F3 B footprint during PCB layout.

Part Context

This part belongs to Panasonic's series of resistor-biased digital transistors designed for space-saving applications. The DRA9143Z0L specifically utilizes the SSMini3 F3 B package, which measures 1.6 x 1.6 mm. It serves as a direct replacement for discrete NPN/PNP combinations where integrated biasing reduces component count and assembly complexity.
