MGL Avionics VHF Radio repair

[steve_w]

Can anyone identify the component with the hole in it?  I am repairing an MGL Avionics VHF Transceiver from my brother's gyro copter.

MGL have discontinued this model so I think manufacturer support is unlikely, but i'll try.

My brother was charging the battery on his gyro, all plastic construction, with the radio on, yeah I know! pilots WTF.

The component is either in series with or hanging off the 12V supply line.

Any advice or circuits would be appreciated.

Does the top line say GGK? if so, 60V TVS: https://www.diodes.com/assets/Datasheets/ds19003.pdf

Thanks your answer is spot on.

I identified a replacement at element 14 for the princely sum of 6 cents pity about the 25 bucks for delivery :-(
