Overview
The DTA023JMT2L is a single PNP digital transistor manufactured by Rohm Semiconductor, featuring integrated bias resistors within a VMT3 (SOT-723) surface-mount package. It supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. The device incorporates a base resistor (R1) of 2.2kΩ and an emitter-base resistor (R2) of 47kΩ. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at 5mA/10V, a maximum saturation voltage of 150mV at 500µA/5mA, and a transition frequency of 250MHz. Power dissipation is rated at 150mW.
Feature Summary
- Integrates base and emitter-base resistors to simplify circuit design by eliminating external components.
- Provides high-speed switching capabilities with a 250MHz transition frequency for efficient signal processing.
- Offers low saturation voltage to minimize power loss during conduction states.
- Utilizes a compact SOT-723 package suitable for space-constrained surface-mount applications.
Applications
- General-purpose switching circuits in consumer electronics.
