Instantaneous electrical suppressor response speed is very fast (ps level); The surge resistance is worse than that of discharge tube and varistor. The pulse power of the 10/1000s wave ranges from 400 W to 30 kW, and the peak pulse current ranges from 0.52 A to 544 A; The breakdown voltage has a series of values of 6.8V~550V, which is convenient for the use of different voltage circuits. The packaging forms are axial lead type and patch type. The patch types are SMAJ(400W), SMBJ(600W), SMCJ(1.5kW), SMDJ(3kW) series, and the axial lead types are P4KE (400W), SA(500W), P6KE(600W), 1.5KE(1.5kW), kW. In addition, there are BZW04(400W) series glass passivated junction TVS tubes.
