Features and Description
Bidirectional crowbar protection
Voltage: range from 120 V to 270 V
Low VBO / VR ratio
Micro capacitance equal to 12 pF @ 50 V
Low leakage current : IR = 2 µA max
Holding current: IH = 150 mA min
Repetitive peak pulse current: IPP = 80 A (10/1000 µs)

The SMP80MC is a series of micro capacitance transient surge arrestors designed for the protection of high debit rate communication equipment on CPE side. Its micro capacitance avoids any distortion of the signal and is compatible with digital transmission like ADSL2 and ADSL2+.
This is the first Trisil series for which the capacitance (Cj) does not depend on the device voltage and this is the first 80 A device with such a low capacitance. By fine tuning the trade-off Repetitive peak pulse current / Capacitance for broad-band transmission, ST offers the capability for the customer to decrease the capacitance to 7pF @ VR = 50V bias and 13.5pF @ VR = 2V bias (with a VRMS = 1V and F = 1MHz signal).
Its lowest micro capacitance avoiding any distortion of the signal and its strong compatibility with worldwide telecom standards, offer the best performance with the highest security level.
Suitable for ADSL2+ and VDSL, the new SMP80MC series offers the lowest junction capacitance and complies with subscriber-side standards for telecom equipment protection.
All SMP80MC devices are packaged in SMB.
