Built upon Magnachip’s Field Stop Trench technology, the newly introduced AMBQ40T120RFRTH (1200V) and AMBQ40T65PHRTH (650V) offer a minimum short-circuit withstand time of 10µs. This level of ruggedness enables PTC heaters to be protected from a permanent failure in the event of overcurrent conditions.
Furthermore, the thick and large heat sink of the TO-247 package allows these new IGBTs to excel in heat dissipation. Therefore, these IGBTs are well-suited for applications requiring high power and efficiency, such as both the upper and lower sides of power management integrated circuits of PTC heaters.
