Key parameters of the devices include voltage range from 120V to 270V, a maximum leakage current of only 2A[acute accent]A, a maximum breakover voltage up to 345V and a minimum holding current of 150mA.
Upon application of a voltage exceeding the breakover voltage, the TSPDs switch from high off-state impedance to low on-state impedance thus allowing the excess surge current to be directed away from sensitive circuits.
The typical breakover voltage of the part is 32V (when tested with a 22nF capacitance in parallel with the device).
