TPG619C6 from TECH PUBLIC, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	RF2	passive	RF port 2. One of the two throw ports of the SPDT switch; connected to RFC when VC2=High, VC1=Low. Requires a series DC blocking capacitor C1 (56 pF for operation >500 MHz).
2	GND	power_in	Ground reference for the GaAs SPDT switch die.
3	RF1	passive	RF port 1. One of the two throw ports of the SPDT switch; connected to RFC when VC1=High, VC2=Low. Requires a series DC blocking capacitor C1 (56 pF for operation >500 MHz).
4	VC1	input	Switch control input 1. Logic High (2.8 V to 5 V) selects the RFC-to-RF1 path; Logic Low (-0.2 V to 0.2 V) deselects it. Absolute max -6.0 V to +6.0 V. Very low control current (typ 4 uA, max 100 uA).
5	RFC	passive	RF common port. Connected to RF1 or RF2 depending on the state of VC1/VC2. Requires a series DC blocking capacitor C1 (56 pF for operation >500 MHz).
6	VC2	input	Switch control input 2. Logic High (2.8 V to 5 V) selects the RFC-to-RF2 path; Logic Low (-0.2 V to 0.2 V) deselects it. Absolute max -6.0 V to +6.0 V. Very low control current (typ 4 uA, max 100 uA).
