NSBA143TDXV6T5

Overview

The NSBA143TDXV6T5 is a dual PNP digital transistor manufactured by onsemi. It integrates two independent PNP bipolar junction transistors with built-in bias resistors within a single SOT-563 (CASE 463A-01) surface-mount package. The device supports a maximum collector current of 100mA and a collector-emitter voltage rating of 50V. Designed for small-signal switching applications, it offers a power dissipation capability of 500mW. The component utilizes silicon technology and features lead-free construction compliant with RoHS standards.

Feature Summary

• Integrates two independent PNP transistors with pre-biased resistors in a compact footprint
• Eliminates external resistor requirements to simplify circuit design and reduce board space
• Provides consistent DC current gain characteristics due to integrated biasing network

Applications

• General-purpose switching circuits requiring dual PNP logic interfaces
• Low-power signal processing stages in consumer electronics
• Interface drivers for microcontroller output expansion

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact packaging configuration and tape-and-reel specifications. Ensure compliance with current environmental directives such as RoHS before integration into regulated products. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required in a minimal surface-mount package. Evaluate the 50V voltage rating and 100mA current limit against circuit load requirements. Confirm that the SOT-563 thermal performance meets the application's power dissipation needs under expected operating conditions.
