TT1201SBX

Shenzhen JingYang · ESD And Surge Protection (TVS/ESD) · DFN1006-2L

TT1201SBX from Shenzhen JingYang, in a DFN1006-2L. 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 bidirectional One of two bidirectional TVS terminals; the device protects one data line between I/O_1 and I/O_2 with a 12.0 V nominal reverse working voltage (VRWM) and 0.35 pF typical parasitic capacitance at VR = 0 V, f = 1 MHz.
2 I/O_2 bidirectional The other bidirectional TVS terminal, paired with I/O_1, with reverse leakage of 1.0 µA maximum at VRWM = 12 V and T = 25 °C.
