SBOS825D September 2019 – July 2021 TMCS1101
For applications where current is pulsed between a high current and no current, the allowable capabilities are limited by short-duration heating in the leadframe. The TMCS1101 can tolerate higher current ranges under some conditions, however, for repetitive pulsed events, the current levels must satisfy both the pulsed current SOA and the RMS continuous current constraint. Pulse duration, duty cycle, and ambient temperate all impact the SOA for repetitive pulsed events. Figure 8-6, Figure 8-7, Figure 8-8, and Figure 8-9 illustrate repetitive stress levels based on test results from the TMCS1101EVM under which parametric performance and isolation integrity was not impacted post-stress for multiple ambient temperatures. At high duty cycles or long pulse durations, this limit approaches the continuous current SOA for a RMS value defined by Equation 15.
