WebJan 13, 2024 · A BJT has negative temperature coefficient, so current-sharing resistors are necessary during parallel operation of BJTs. As BJT has negative temperature coefficient, secondary breakdown occurs. With decrease in resistance, the current increases. This increased current over the same area results in hot spots and breakdown of the BJT. Web3. Forward-Biased Safe Operating Area (FBSOA) Capability Avalanche Energy: The avalanche condition arises when the voltage across the device exceeds its breakdown voltage. Two types of failures occur in this condition. The first failure called the “BJT latching”, occurs when the current induces sufficient voltage across the device’s internal
