Overview
The NSBC143TPDXV6T5 is a dual digital transistor from onsemi, configured as two NPN transistors with integrated bias resistors in a SOT-563 surface-mount package. It features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. The device includes a typical base resistor value of 4.7 kOhms and guarantees a minimum DC current gain (hFE) of 160. Power dissipation is rated at 357 mW, with an operating temperature range spanning from -55°C to +150°C.
Feature Summary
- Integrates two NPN transistors with monolithic bias resistor networks to replace discrete components and external resistor circuits.
- Provides high DC current gain for efficient signal switching and amplification applications.
- Designed for surface-mount assembly in compact six-pin SOT-563 packages.
Applications
- General-purpose switching circuits
- Driver stages for logic interfaces
- Biasing networks in analog signal processing
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Ensure that any alternative part numbers are cross-referenced with the latest datasheet revisions to avoid functional mismatches in critical designs.
Selection Notes
Select this component when a dual NPN configuration with fixed bias resistance is required. Compare the 4.7 kOhm base resistor value against circuit requirements to ensure proper input impedance matching. Verify that the 50 V voltage rating exceeds the maximum expected load conditions.
Part Context
This part belongs to the DTC143TP series of Bias Resistor Transistors (BRTs). These devices are engineered to simplify circuit design by combining transistors and resistors into a single semiconductor die, reducing board space and assembly complexity compared to discrete solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official distributor databases or manufacturer substitution guides for verified equivalents.
