eGuard0522P and eGuard0524P Data Line Protection
SMC Diode Solutions offers their eGuard0522P and eGuard0524P data line protection with ultra-low capacitance of 0.35 pF typical I/O to I/O
SMC Diode Solutions' eGuard0522P and eGuard0524P are ultra-low-capacitance transient voltage suppressor (TVS) arrays designed to protect sensitive semiconductor components from electrical overstress (EoS) when interfaced to two/four high-speed data lines. The ultra-low capacitance (0.35 pF typical I/O to I/O) of the eGuard0522P and eGuard0524P ensures negligible signal attenuation at data rates up to 3.5 GHz. The solid-state construction ensures fast clamping of electrical overstress transients resulting from electrostatic discharge (ESD), electrical fast transients (EFT), or cable discharge events (CDE).
In addition to ultra-low capacitance, the eGuard0522P provides superior surge-current capability and excellent voltage-clamping performance. The surge-current capability (8 x 20 µs) is rated at 7 A, approximately 33% higher than industry norms. The tight clamping ratio (VC/VRWM) of 1.9 (typical at 1 A) 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 eGuard0522P is designed to protect up to two data lines. It is packaged in a RoHS/WEEE compliant, 6-pin DFN that has a very-low package profile of 0.55 mm (nominal). The combination of ultra-low capacitance, high surge capability, tight clamping ratio, and low package profile make the eGuard0522P the ideal choice for today’s ESD-sensitive, space-constrained applications.
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 0.5 mm (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.
