Breakdown occurs at a minimum of 19.8 V, and clamping is guaranteed at 31.9 V max when the peak pulse current hits 47 A. Bidirectional — a single device protects both polarities, useful on AC signal lines or DC rails where reverse-connection transients are possible. The 1500 W rating at 10/1000 µs waveform is the standard TVS power metric; derate for shorter pulse widths or higher ambient temperatures per the TransZorb datasheet curve. ## Through-hole DO-201AA — rework and board-fit DO-201AA axial-lead package, through-hole mount. The leads are robust enough for hand soldering or wave — no special thermal profile needed. Polarity is marked by the cathode band; on a bidirectional part the band is present but the device clamps both ways. ## General-purpose protection — no power-line rating Marked for general-purpose applications. The power-line protection flag is 'No' — this is not a primary AC mains suppressor; it is intended for DC rail or signal-line transient clamping in control, instrumentation, or automotive auxiliary circuits.","metaTitle":"Vishay 1.5KE22C-E3/54 TVS, 1500W, Bidirectional, DO-201AA","metaDescription":"Vishay TransZorb 1.5KE22C-E3/54 bidirectional TVS, 1500W peak pulse, 17.8V standoff, 31.9V clamp.
