Package: SOT-143FUXINSEMITVS - DiodesOperating Voltage: 5.0 VClamping Voltage: 10 V (at 1A)Junction Capacitance: 0.8 pF (I/O to GND)Peak Pulse Power: 60 W (8/20µs)ESD Protection: ±15kV (air), ±8kV (contact)

PRTR5V0U2X-FS is an ultra-low capacitance TVS array for protecting two high-speed 5V data lines. Key alternatives exist with similar pinouts but require careful review of capacitance and power ratings.

AI replacement insight

Electrical riskhigh

Mismatched capacitance or lower power rating can cause system failure.

Package risklow

All viable candidates share the SOT-143 package and a compatible pinout.

Can it be replaced directly?

Direct replacement for PRTR5V0U2X-FS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

SR05-ES offers the most balanced profile as a potential upgrade, matching key parameters and improving power handling.

Main risk

The primary risk is mismatched capacitance, which can degrade signal integrity on high-speed interfaces like USB or HDMI.
