Frequently Asked Questions
What is the maximum collector-emitter saturation voltage of the FSB560 at 2 A collector current?
The FSB560 features ultra-low saturation voltage (VCE_sat) of approximately 0.15-0.2 V when operated at maximum 2 A collector current with adequate base drive. At 2 A × 0.2 V, the device dissipates only 0.4 W in saturation, compared to 2-3 W in standard BJTs, significantly improving battery life and reducing thermal management requirements. This low saturation voltage is critical for relay driver and solenoid applications where switching high inductive loads; the quick voltage drop to near-ground level provides fast, clean logic-level switching from 5 V or 3.3 V controllers without external power supply or gate drive circuits.
Can the FSB560 with 100 minimum hFE be directly driven by 5 V logic outputs or Arduino GPIO pins?
Yes, the FSB560 with minimum hFE of 100 can be reliably driven by 5 V or 3.3 V logic outputs providing 5-10 mA base current. To achieve 2 A collector saturation, the required base current is approximately IB = IC / hFE = 2 A / 100 = 20 mA maximum. Most GPIO outputs can source 20-40 mA, providing adequate drive with 2.2-4.7 kΩ base resistor series resistance. This direct interface eliminates need for Darlington pairs or FET drivers in low-side switching applications like relay, LED, and solenoid control on Arduino-based automation platforms.
What is the maximum voltage and power rating of the FSB560 for motor control applications?
The FSB560 is rated for maximum 60 V collector-emitter voltage (VCE_max) and 2 A continuous collector current, enabling safe operation from 12 V, 24 V, and 48 V industrial DC supplies. At 24 V × 2 A, the FSB560 can safely switch 48 W loads when used as a low-side switch, suitable for small DC motors and solenoid coils in factory automation. The ultra-low 0.15-0.2 V saturation voltage minimizes dissipative losses; at 24 V, only 0.4 W is wasted as heat even at maximum current, compared to 5-10 W in non-saturating switches, making it ideal for battery-powered mobile robotics and solar-powered control systems.
How does the FSB560 SOT-23 package compare to larger switching transistors for compact relay driver circuits?
The FSB560 SOT-23 3-pin package measures approximately 2.9 mm × 2.8 mm × 1.3 mm height, enabling compact relay driver circuits occupying minimal PCB real estate compared to larger TO-220 or TO-39 packages. A single SOT-23 relay driver for a 24 V / 2 A solenoid coil consumes under 1 cm² including base resistor and protection diode, ideal for space-constrained industrial PLC I/O modules and mobile robot control boards. The high current density (2 A in SOT-23) requires careful PCB thermal design; most applications use 1-2 oz copper pour and thermally-via connections to the ground plane for reliable continuous operation.
