Circuit Diagram
The SRV05-4A is a low capacitance TVS (Transient Voltage Suppressor) array designed to protect sensitive
semiconductor components from electrical overstress when interfaced to high-speed data lines. The low capacitance
(1.5pF typical I/O to I/O) of the SRV05-4A 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 low capacitance, the SRV05-4A provides superior surge current capability and excellent voltage clamping
performance. The surge current capability (8x20μs) is rated at 20A; approximately 50% higher than industry norms.
Furthermore, the tight clamping ratio (VC/VRWM) of 1.75 (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 SRV05-4A is in a 6-lead SOT-23 package. The leads are finished with lead-free matte tin. Each device will protect up
to four high-speed lines. They may be used to meet the ESD immunity requirements of IEC 61000-4-2. The combination
of small size, low capacitance, and high surge capability makes them ideal for use in applications such as 10/100
Ethernet, USB 2.0, and video interfaces.
