Low Clamping Voltage:
devices are designed and built using

BCD
Typical 8V at 10A 100ns, TLP, VCC to VSS
Typical 9V at 10A 100ns, TLP, I/O to VSS
11.2V at 12A 8μs/20μs, VCC to VSS
11V at 10A 8μs/20μs, I/O to VSS
proprietary process based on BCD standard
technology. These devices integrate the various diodes,
transistors and resistors required to build these ITVS
products. These diodes and transistors feature low
parasitic resistance and the diodes also exhibit low
capacitance. Using these devices, BCD is able to
design voltage clamping products where low
capacitance associated with low dynamic resistance is
required.
