SRV05-4A Datasheet | SMC Diode

Description The SRV05-4A is a low capacitance TVS (Transient Voltage Suppressor) array designed to protect sensitive semiconductor ponents from electrical overstress when interfaced to high-speed data lines. The low capacitance (1.5p F typical I/O to I/O) of the SRV05-4A ensures negligible signal attenuation at data rates up to 3.5GHz. The solidstate 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 bination 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.
