SP725 Series Diode Array

SP725 series 5 pF 8 kV diode array from Littelfuse

Image of Littelfuse's SP725 - SCR/Diode Array for ESD and Overvoltage Protection Littelfuse's SP725 series - lead-free / green SCR / diode array for ESD and overvoltage protection. The SP725 is an array of SCR / diode bipolar structures for ESD and overvoltage protection of sensitive input circuits. The SP725 has 2 protection SCR / diode device structures per input. There are a total of four available inputs that can be used to protect up to four external signal or bus lines. Overvoltage protection is from the IN (Pins 1 - 4) to V+ or V-.

The SCR structures are designed for fast triggering at a threshold of one +VBE diode threshold above V+ (Pin 5,6) or one -VBE diode threshold below V- (Pin 7,8). 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.
