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. DC-3 GHz RF I/O connected to RFC when VC2=High/VC1=Low (insertion loss ~0.4 dB @ 2.5 GHz). Requires a series DC blocking capacitor C1 (56 pF for >500 MHz operation). |+| 2 | GND | power_in | Ground reference for the RF switch. Connect to system ground with a low-inductance path. |+| 3 | RF1 | passive | RF port 1. DC-3 GHz RF I/O connected to RFC when VC1=High/VC2=Low (insertion loss ~0.4 dB @ 2.5 GHz). Requires a series DC blocking capacitor C1 (56 pF for >500 MHz operation). |+| 4 | VC1 | input | Switch control input 1. Logic High (2.8 V to 5 V) selects the RFC-RF1 path (insertion loss); Logic Low (-0.2 V to 0.2 V) isolates RF1. Abs max -6.0 to +6.0 V; |VC1-VC2| <= 6.0 V. Control current typ 4 uA (max 100 uA). |+| 5 | RFC | passive | RF common port. Routed to RF1 or RF2 per VC1/VC2 truth table. DC-3 GHz operation with VSWR ~1.2 and IIP3 ~55 dBm. Requires a series DC blocking capacitor C1 (56 pF for >500 MHz operation). |+| 6 | VC2 | input | Switch control input 2. Logic High (2.8 V to 5 V) selects the RFC-RF2 path (insertion loss); Logic Low (-0.2 V to 0.2 V) isolates RF2. Abs max -6.0 to +6.0 V; |VC1-VC2| <= 6.0 V. Complementary drive with VC1 for standard SPDT operation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-363 |+| Category | Interface |+| Pins | 6 |++## Ordering variants++- `TPAS179-92LF92LF`++## CAD (KiCad official)++- Symbol: `TPAS179-92LF`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SOT-363 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TECH PUBLIC datasheet](docs/tpas179-92lf-datasheet.pdf) (5 pp, sha256 `4cf1ffe39a23345a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
