TTA0501MDX from Shenzhen JingYang, 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 | I/O_1 | passive | I/O_1 is one terminal of the bidirectional TVS, with a nominal reverse working voltage VRWM of 5.0 V, reverse leakage of 0.1 µA maximum at VRWM = 5 V, and parasitic capacitance of 7.5 pF typical (15 pF maximum) to I/O_2 at 0 V and 1 MHz. |
| 2 | I/O_2 | passive | I/O_2 is the other terminal of the bidirectional TVS, protecting one data, control or power line against ESD at ±30 kV (air and contact) per IEC 61000-4-2 and 40 A per IEC 61000-4-4 (5/50 ns), with an operating temperature range of -55 to +125 °C. |
