LESD5Z5.0CT1G from UMW, in a SOD-523. 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 | 1 | passive | Terminal 1 of the bidirectional TVS diode, connected to the protected I/O line (working voltage 5V, reverse leakage max 1.0 µA at VRWM = 5V). |
| 2 | 2 | passive | Terminal 2 of the bidirectional TVS diode, connected to the opposite side (ground or return) of the protected I/O line (VBR 5.6V min at IT = 1mA, clamping voltage 15.0V max at IPP = 5A, 8/20µs). |
