The eGuard0524P* is an ultra low capacitance TVS (Transient Voltage Suppressor) array designed to protect sensitive
semiconductor components from electrical overstress when interfaced to high-speed data lines. The ultra low
capacitance (0.35pF typical I/O to I/O) of the eGuard0524P ensures negligible signal attenuation at data rates up to
3.5GHz. The solid-state construction ensures fast clamping of electrical overstress transients resulting from ESD
(electrostatic discharge), EFT (Electrical Fast Transients) or CDE (Cable Discharge Events).
In addition to ultra low capacitance, the eGuard0524P provides superior surge current capability and excellent voltage
clamping performance. The surge current capability (8x20μs) is rated at 7A; approximately 33% higher than industry
norms. Furthermore, the tight clamping ratio (VC/VRWM) of 1.9 (typical at 1A) ensures harmful transients are clamped
quickly and close to the normal working voltage of the circuit. The super tight clamping ratio is 30% better than
industry norms and ensures superior protection of sensitive integrated circuits.
The eGuard0524P is designed to protect up to four data lines. It is packaged in a RoHS/WEEE compliant, 10 pin DFN
that has a very low package profile of 0.5mm (nominal). The combination of ultra low capacitance, high surge
capability, tight clamping ratio and low package profile make the eGuard0524P the ideal choice for today’s ESD
sensitive, space constrained applications.
