SS24 2A Schottky Barrier Rectifier Diode (40V, SMB/DO-214AA)

Maximize efficiency and protect your microcontrollers from destructive inductive spikes with the SS24 Schottky barrier rectifier. When driving inductive loads like DC motors, solenoids, or mechanical relays, turning off the power creates a massive reverse voltage spike that can instantly fry your MOSFETs or Arduino. By placing this high-speed diode in parallel with your load (as a freewheeling/flyback diode), it safely shunts that destructive energy away.

Unlike standard silicon diodes, the SS24 features an ultra-low forward voltage drop. This means when used for reverse-polarity protection in custom power supplies or solar charging circuits, it wastes significantly less energy as heat, ensuring more power reaches your actual electronics. Rated for a robust 2 Amps of continuous current and a 40V maximum reverse voltage, it provides an excellent safety margin for 12V and 24V DIY projects. Housed in the industry-standard SMB (DO-214AA) surface-mount package, it offers better thermal dissipation than smaller SMA diodes while still saving valuable PCB space.

Key Features:

• Flyback Champion: The ultimate freewheeling diode for safely discharging inductive kickback from motors, relays, and solenoids.

• Ultra-Low Voltage Drop: Minimizes power loss and heat generation, making it highly efficient for reverse-polarity protection circuits and DC-DC converters.

• 2A Continuous Current: Safely handles medium-power loads, bridging the gap between small-signal diodes and massive 5A+ rectifiers.

• Optimized SMB Package: The DO-214AA footprint provides excellent heat transfer to the PCB copper planes while remaining easy to solder by hand.
