MSSR05.TCT
MSKSEMI · ESD And Surge Protection (TVS/ESD) · SOT-143
MSSR05.TCT from MSKSEMI, in a SOT-143. 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 | GND | power_in | Ground reference at the anode of the internal 5V zener TVS diode, shared by the lower steering diodes (marked pin-1 dot corner). |
| 2 | IO2 | passive | Protected line connected to the mid-point of one steering-diode pair, clamped for ±30kV IEC 61000-4-2 ESD with 1.2pF typical capacitance and 5V working voltage. |
| 3 | IO1 | passive | Protected line connected to the mid-point of the other steering-diode pair, clamped for ±30kV IEC 61000-4-2 ESD with 1.2pF typical capacitance and 5V working voltage. |
| 4 | VCC | power_in | Upper rail connected to the cathode of the internal 5V zener TVS diode, with a stated working voltage VRWM of 5V. |
