# TLP5771H

**TOSHIBA** · Gate Drive Optocoupler · SO-6

TLP5771H from TOSHIBA, in a SO-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 | Anode | passive | LED anode input; the LED is driven with an input on-state current IF(ON) of 5 to 10 mA (recommended) and an absolute maximum forward current of 20 mA. |
| 2 | N.C. | unconnected | No connection. |
| 3 | Cathode | passive | LED cathode input; the input off-state voltage VF(OFF) must be at most 0.8 V to keep the output low. |
| 4 | GND | power_in | Output-side ground; a 1 µF ceramic bypass capacitor must be connected between pin 6 and pin 4, placed within 1 cm of the pins. |
| 5 | VO | output | Totem-pole rail-to-rail output with peak output current of ±1.0 A (max); output goes high when the LED is on. |
| 6 | VCC | power_in | Positive supply, 10 to 30 V operating range; needs a 1 µF ceramic bypass capacitor to pin 4. |
