RCLAMP0504F from UMW, in a SOT-363. 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 | CH1 | bidirectional | Channel 1 I/O line of the ESD/surge protector, rated for a reverse working voltage of 5V with 0.3pF typical I/O-to-I/O capacitance. |
| 2 | GND | power_in | Ground reference pin that the I/O clamps are referenced to, with parasitic capacitance specified from each I/O pin to ground. |
| 3 | CH2 | bidirectional | Channel 2 I/O line of the ESD/surge protector, rated for a reverse working voltage of 5V with 0.3pF typical I/O-to-I/O capacitance. |
| 4 | CH3 | bidirectional | Channel 3 I/O line of the ESD/surge protector, rated for a reverse working voltage of 5V with 0.3pF typical I/O-to-I/O capacitance. |
| 5 | VDD | power_in | Power line pin of the device, which the datasheet states is protected as one power line within a 5V low operating voltage. |
| 6 | CH4 | bidirectional | Channel 4 I/O line of the ESD/surge protector, rated for a reverse working voltage of 5V with 0.3pF typical I/O-to-I/O capacitance. |
