SMAJ6.5A-TR 6.5V Unidirectional TVS Diode (400W, SMA/DO-214AC)

Ensure rock-solid overvoltage protection for your critical electronics with the SMAJ6.5A-TR Transient Voltage Suppressor (TVS) diode. When designing custom robotics, RC vehicles, or drone Power Distribution Boards (PDBs), inductive spikes from heavy loads can wreak havoc on your circuits. While 5.0V TVS diodes are common, they can sometimes trigger or leak current if your 5V power supply fluctuates slightly upwards. This 6.5V variant provides the perfect "breathing room" for 5V rails and is the absolute go-to choice for protecting 6V BEC (Battery Eliminator Circuit) lines dedicated to high-torque servos.

Installed in parallel with your power rail, this unidirectional diode remains completely dormant during normal operation. However, the moment a destructive voltage spike exceeds its threshold, it instantly clamps the voltage and harmlessly shunts up to 400 Watts of surge energy directly to ground. Housed in the rugged, easy-to-solder SMA (DO-214AC) surface-mount package, it is a mandatory safety mechanism for safeguarding your expensive microcontrollers, sensors, and receiver modules from catastrophic electrical failure.

Key Features:

• Ideal 6.5V Threshold: Provides a safe operating margin for 5V logic systems prone to minor fluctuations, and perfectly protects standard 6V servo power rails.

• Massive 400W Surge Rating: Effortlessly absorbs brutal inductive kickbacks from stalling motors and heavy mechanical actuators.

• Unidirectional Clamping: Designed specifically for DC power lines, ensuring dangerous positive spikes are neutralized while blocking reverse polarity.

• Rugged SMA Package: The industry-standard DO-214AC footprint handles high thermal loads and is incredibly easy to assemble on custom DIY PCBs.
