SBOS820A September 2019 – June 2020 TMCS1100
Single higher-current events that are shorter duration can be tolerated by the TMCS1100, because the junction temperature does not reach thermal equilibrium within the pulse duration. Figure 34 shows the short-circuit duration curve for the device for single current-pulse events, where the leadframe resistance changes after stress. This level is reached before a leadframe fusing event, but should be considered a upper limit for short duration SOA. For long-duration pulses, the current capability approaches the continuous rms limit at the given ambient temperature.
