The SP721ABTG is an array of SCR/Diode bipolar structures for ESD and over-voltage protection to sensitive input circuits. The SP721 has 2 protection SCR/Diode device structures per input. There are a total of 6 available inputs that can be used to protect up to 6 external signal or bus lines. Over-voltage protection is from the IN (Pins 1 - 3 and Pins 5 - 7) to V+ or V-. The SCR structures are designed for fast triggering at a threshold of one +VBE diode threshold above V+ (Pin 8) or a -VBE diode threshold below V- (Pin 4). From an IN input, a clamp to V+ is activated if a transient pulse causes the input to be increased to a voltage level greater than one VBE above V+. A similar clamp to V- is activated if a negative pulse, one VBE less than V-, is applied to an IN input. Single input ESD interface capability of 4 kV by contact and 15 kV through the air Peak single pulse current capability of ±3A (8/20μs) Single-ended voltage range to +30V and differential voltage range to ±15 V Fast switching, with 2 ns rise time Low typical input leakage of 1 nA at 25℃ Low typical input capacitance of 3 pF 14 SCR–diode Pairs Operate at temperatures ranging from –40°C to +105°C Meet MIL STD 3015.7, IEC 61000-4-2, and IEC 61000-4-5 standards
