ElecSuper
Needs validationlow risk
A strong alternative with matching package, voltage, power, and ultra-low capacitance. Pinout verification is required.
Best Alternatives to SR05-ES
SR05-ES is a 5V, 2-line, ultra-low capacitance TVS diode in a SOT-143 package for high-speed interface protection. Key alternatives must match its 0.6pF capacitance and 180W power rating to ensure performance and safety.
AI replacement insight
Electrical riskhigh
Higher capacitance can cause signal degradation. Lower power rating compromises protection.
Package risklow
SOT-143 is a standard package, but internal pin configuration must be verified.
Can it be replaced directly?
Direct replacement for SR05-ES should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
PRTR5V0U2X-ES offers the most direct replacement path due to its nearly identical specifications for voltage, power, and capacitance.
Main risk
The primary risk when substituting is increased junction capacitance, which can degrade signal integrity on high-speed lines like USB or HDMI.
