Safe operating area explained
Where both current and voltage are plotted on logarithmic scales, the borders of the SOA are straight lines: IC = ICmax — current limitVCE = VCEmax — voltage limitIC VCE = Pmax — dissipation limit, thermal breakdownIC VCE = const — this is the limit given by the secondary breakdown (bipolar junction transistors only) … See more For power semiconductor devices (such as BJT, MOSFET, thyristor or IGBT), the safe operating area (SOA) is defined as the voltage and current conditions over which the device can be expected to operate without self-damage. See more For a device that makes use of the secondary breakdown effect see Avalanche transistor Secondary … See more Transistors require some time to turn off, due to effects such as minority carrier storage time and capacitance. While turning off, they may be damaged depending on how the load responds (especially with poorly snubbed inductive loads). The reverse … See more • Derating See more In their early history, MOSFETs became known for their absence of secondary breakdown. This benefit was due to the fact that ON-resistance increases with increasing … See more The most common form of SOA protection used with bipolar junction transistors senses the collector-emitter current with a low-value series resistor. The voltage across this resistor … See more WebMar 1, 2024 · The degradation mechanism of the safe operating area is explained by the 1-D electro-thermal coupling model based on Sentaurus TCAD. When the critical short-circuit duration is 12μs, the single short-circuit failure mode of DUT with 400 V dc-bus voltage is a gate-source short-circuit failure.
