Data Sheet General Purpose ITVS, 4 I/Os, CI/O-VSS<1.5pF AT2042 General Description Features BCD ITVS (Integrated Transient Voltage Suppression) devices are designed and built using a BCD 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. • • • • • • • • Low Clamping Voltage: Typical 9V at 10A 100ns, TLP, I/O to VSS 11V at 10A 8μs/20μs, I/O to VSS IEC 61000-4-2: ±30kV (I/O to VSS, Air) ±30kV (I/O to VSS, Contact) IEC 61000-4-5: ±10A (I/O to VSS) Input Capacitance from I/O to VSS: 1.2pF TLP Dynamic Resistance, I/O to VSS: 0.25Ω Monolithic Silicon Technology Application The BCD AT2042 is a general purpose, high performance and low cost device suitable for protecting high speed data interfaces.
