# PTLC0514TS

**PTTC Polytronics Tech** · ESD And Surge Protection (TVS/ESD) · SOT-23-6

PTLC0514TS from PTTC Polytronics Tech, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | ESD-protected data/power line input with steering diodes to Vcc and GND, 0.5 pF typ. I/O-to-I/O capacitance and ±15kV contact / ±20kV air IEC61000-4-2 protection. |
| 2 | GND | power_in | Ground reference of the TVS array, connected to the common return of the steering diodes. |
| 3 | I/O2 | passive | ESD-protected data/power line input with steering diodes to Vcc and GND, 0.6 pF typ. I/O-to-GND capacitance (0.8 pF max) at VR = 0V, 1MHz. |
| 4 | I/O3 | passive | ESD-protected data/power line input with steering diodes to Vcc and GND, 5.0 V reverse stand-off voltage and 16 V max clamping at IPP = 6.0 A. |
| 5 | Vcc | power_in | Positive rail of the TVS array where the avalanche diode connects, with 5.0 V reverse stand-off voltage (VRWM) and 6.0 V min breakdown at 1 mA. |
| 6 | I/O4 | passive | ESD-protected data/power line input with steering diodes to Vcc and GND, 100 W peak pulse power (8/20µs). |
