ME701203 Electrical Characteristics

The first graph, titled Maximum On-State Characteristics, shows how the instantaneous on-state voltage (VTM) increases with the on-state current (IFM) at a junction temperature of 25°C. This curve helps designers estimate the voltage drop across the module when it conducts current, which in turn influences power loss and heat generation in operation. As the current increases, the voltage drop rises nonlinearly, indicating higher conduction losses at elevated loads.

The second graph, Maximum Allowable Peak Surge (Non-Repetitive) Current, illustrates the module’s capacity to handle brief surges in current. It shows how the maximum non-repetitive surge current (ITSM) decreases as the number of 60 Hz cycles increases. For short-duration surges (1–2 cycles), the device can handle up to 400 A, but for longer surges, the limit drops, highlighting the need to protect the module from extended overcurrent conditions.

The third graph, Maximum Allowable Case Temperature, demonstrates the relationship between DC output current (IO) and the maximum case temperature (TC) the device can safely operate at. As the output current increases, the allowable case temperature decreases. For instance, at 30 A, the case temperature should not exceed 100°C. This emphasizes the importance of proper thermal management, such as heatsinking, to ensure reliability during higher load conditions.

The last graph shows the relationship between the DC output current (IO) and the maximum power dissipation (PAV(max)) for both resistive and inductive loads. As the output current increases, power dissipation rises significantly, reaching up to about 75 watts at 35 amperes. This curve is essential for understanding how much thermal energy needs to be managed in a system design.
