DRA3143Z0L

Overview

The Panasonic DRA3143Z0L is a PNP digital transistor featuring a built-in bias resistor, housed in the SSSMini3 F2 B surface-mount package. It provides a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device incorporates a typical input resistance of 47 kΩ and supports a maximum power dissipation of 100 mW. Designed for high-temperature environments, it operates up to +150 °C. This single-transistor configuration integrates internal circuitry to simplify logic interface design while maintaining compact physical dimensions suitable for dense PCB layouts.

Feature Summary

• Integrates a built-in bias resistor to reduce external component count and simplify circuit design.
• Engineered with low collector-emitter saturation voltage for efficient switching performance.
• Constructed using silicon epitaxial planar technology for reliable operation in digital circuits.
• Compliant with halogen-free standards and RoHS directives for environmental safety.

Applications

• Logic level shifting and interface circuits between microcontrollers and peripheral devices.
• Driver stages for small-signal relays and solenoids requiring compact packaging.
• Switching applications in portable electronic equipment and battery-powered devices.

Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to confirm exact electrical tolerances and tape-and-reel specifications. Confirm compliance status with current regional regulations prior to integration. Ensure that the selected variant matches the required polarity and resistance values for the target application design.

Selection Notes

Select this component when a PNP digital transistor with a 47 kΩ built-in resistor is required in an ultra-small footprint. Compare the -50 V voltage rating and -100 mA current capacity against load requirements. Consider the +150 °C maximum operating temperature for high-thermal environments. Verify that the SSSMini3 package dimensions fit within the available board space constraints.

Part Context

This part belongs to Panasonic's series of resistors-biased transistors designed for digital logic applications. These components replace discrete transistor-resistor networks, saving board area and assembly costs. The DRA3143Z0L specifically utilizes the SSSMini3 package, which is among the smallest form factors available for three-terminal digital transistors, facilitating miniaturization in modern electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available source material. Consult official Panasonic cross-reference guides or distributor databases for verified equivalents. Ensure any replacement maintains identical pinout, polarity, and electrical ratings to guarantee functional compatibility without redesign.
