TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23-6
TPMMQA33VT1G from TECH PUBLIC, 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 | IO1 | passive | Protected line 1 (uni-directional ESD clamp to the common node), 33V reverse working voltage max, 8/20µs 4A peak pulse current. |
| 2 | GND | power_in | Common ground node of the TVS array, tied internally to pin 5; junction capacitance is specified IO to GND at 33pF max. |
| 3 | IO2 | passive | Protected line 2 (uni-directional ESD clamp to the common node), ±30kV air/contact ESD per IEC 61000-4-2. |
| 4 | IO3 | passive | Protected line 3 (uni-directional ESD clamp to the common node), 55V max clamping at 1A (8/20µs). |
| 5 | GND | power_in | Common ground node of the TVS array, tied internally to pin 2. |
| 6 | IO4 | passive | Protected line 4 (uni-directional ESD clamp to the common node), 60V max clamping at 4A (8/20µs). |
