Power
TVS diode
Transient Voltage Suppression diode
Clamps voltage spikes (lightning, ESD) to a safe level.
How it looks

A TVS diode on CORE3588, 5 x 5.4 mm, right behind the USB-C socket.
- 1D1, SMF6V0A: a TVS diode from the USB 5 V input (VBUS_RAW) to ground. The stripe marks the side tied to the 5 V line.

Its smaller cousin next to the socket.
- 1D5: a chip holding several tiny TVS diodes, one for each USB-C data and control line.
How it works
Where it fits
TVS parts guard connectors: USB-C, SD card and debug pins on CORE3588. They protect against ESD; a PolyFuse guards against too much current instead.
