info

The SP721 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.

  • Meets MIL STD 3015.7 and IEC 61000-4-2 standards for ESD protection of HBM interfaces and from discharges through air or by contact
  • Meets IEC 61000-4-5 standards for peak pulse (8/20 µs) capability
  • Designed to provide overvoltage protection against surges up to +30 V
  • 2 ns rise time ensures fast switching
  • Low typical input leakage of 1 nA at 25°C
  • Low typical input capacitance of 3 pF
  • Operating at temperature ranging from –40°C to +105°C
  • Operating Temperature Range - -40°C to 105°C
