SLVS729B February 2008 – March 2016 2016 TPD4E004
The TPD4E004 is a four-channel TVS protection diode array. The TPD4E004 is rated to dissipate contact ESD strikes of ±8-kV contact and ±12-kV air-gap, meeting Level 4 as specified in the IEC 61000-4-2 international standard. This device has a 1.6-pF IO capacitance per channel, making it ideal for use in high-speed data IO interfaces.
TPD4E004 is a TVS which provides ESD protection for up to four channels, withstanding up to ±8-kV contact and ±12-kV air-gap ESD per IEC 61000-4-2. The monolithic technology yields exceptionally small variations in capacitance between any IO pin of TPD4E004. The small footprint is ideal for applications where space-saving designs are important.
The TPD4E004 device is a passive integrated circuit that triggers when voltages are above VBR or below the diodes VF of approximately –0.3 V. During ESD events, voltages as high as ±8-kV contact and ±12-kV air-gap ESD can be directed to ground via the internal diodes. Once the voltages on the protected line fall below the trigger levels of TPD4E004 (usually within 10’s of nano-seconds) the device reverts back to its high-impedance state.
