Try Google. A search revealed it to be a dual Schottky rectifier which can be used with a center-tapped transformer to form a full-wave rectifier.

Dual diode module in a common cathode configuration. They also come in common anode flavors.

Answer; A very DEAD dual schottky diode. You cut his little legs off!

I have seen these used a lot in large car amps DC to DC power supply convertors

In a scooter driver the diode pack would most likely be the back-EMF diode, so if that "broke off" your FETs are probably all fried.

It would prevent EMF spikes as part of a snubber circuit. The cathode would probably then lead to a resistor and capacitor in parallel which would absorb the high voltage induction spikes from the motor.

I've searched a little bit for this Part.
It seems to be a ESAD85-009R - Schottky Barrier Diode.
