Littelfuse has introduced an ultra-low-capacitance protection thyristor in the SOT23-6 package. The SDP Series SIDACtor provides robust over-voltage protection for broadband/xDSL telecommunications equipment with minimal effects on connection speed and reach.
Patent-pending silicon crowbar technology allows for a claimed 45% lower capacitance than clamping devices like transient voltage suppressor (TVS) diodes, as well as providing faster response to surges, ensuring lower overshoot voltages and improved electrostatic discharge (ESD), lightning and power fault protection.
The device is designed for the tertiary or line driver side protection position in VDSL2, ADSL2, ADSL2+ telecommunications applications and general I/O protection functions. Its small-footprint package is well-suited for high-density card designs.
Crowbar devices operate as shunt devices in response to a surge that exceeds the breakover voltage. After switching on, they offer a very low impedance path that diverts transient energy away from the load. In contrast, clamping devices limit the transient voltage to a set value. When the applied voltage reaches the device’s breakdown value, it switches to a much lower resistance value to minimise the transient energy the circuit will experience.
The SDP Series provides a crowbar response to surge events with a maximum threshold of 29 V at 250 V/μs, and offers robust surge protection performance up to 30 A while maintaining low off-state capacitance for better AC protection. It responds quickly to surges, preventing damage caused by the coupling of transient events across the small signal transformer.
