SRV05-4A TVS Array

SMC Diodes Solutions' SRV05-4A is a low-capacitance transient voltage suppressor (TVS) array designed to protect sensitive semiconductor components from electrical overstress when interfaced to high-speed data lines. The low capacitance (1.5 pF typical I/O to I/O) of the SRV05-4A 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 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 (8 x 20 µs) is rated at 20 A, approximately 50% higher than industry norms. The tight clamping ratio (VC/VRWM) of 1.75 (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 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. The SRV05-4A 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 make them ideal for use in applications such as 10/100 Ethernet, USB 2.0, and video interfaces.
