Most transient voltage suppressors (TVS) are rated for 10/1000 μs non-repetitive pulse waveforms, which is an early telecom transient waveform. However, real world transients will have varying pulse widths depending on the source. So how can the maximum transient power and current capability for TVS be derived for conditions other than the 10/1000 µs pulse specified on datasheets? This application note will explore how this can be determined using the peak pulse power vs. pulse time curve.
