Frequently Asked Questions
What is the peak surge current rating of the SMP50-220 and how does it protect against mains transients?
The SMP50-220 handles a 150 A Ipp peak pulse current and a 16 A non-repetitive on-state current. When the line voltage exceeds its 293 V maximum breakover threshold, the thyristor conducts and clamps the transient, protecting downstream components from damage on AC 220 V lines.
Which PCB package does the SMP50-220 use and how does it fit into compact protection circuits?
The SMP50-220 is housed in a DO-214AC (SMA) surface-mount package, which provides a small PCB footprint while supporting up to 150 A Ipp surge current. This makes it suitable for integration close to AC input connectors in compact power adapter and appliance protection layouts.
When is the SMP50-220 preferred over a standard TVS diode for overvoltage protection at 220 V?
The SMP50-220 thyristor is preferred over a TVS diode when a crowbar-action hard clamp is needed, as it latches on once triggered and holds voltage to near zero until current drops. Its 220 V DC off-state and 293 V breakover ratings target AC mains applications where diode-type clamping at fixed voltage is insufficient to protect against sustained overvoltage.
