BUX98A Frequently Asked Questions (FAQ)

  • The maximum SOA for the BUX98A is typically defined by the voltage and current ratings. The transistor can handle up to 100V and 10A, but the SOA curve should be consulted to ensure safe operation.

  • To ensure linear operation, the BUX98A should be biased in the active region, typically between 2-5V on the base with respect to the emitter. The collector-emitter voltage should be around 1-2V, and the collector current should be limited to the recommended maximum.

  • A heatsink with a thermal resistance of around 10-20°C/W is recommended for the BUX98A. The heatsink should be designed to keep the transistor's junction temperature below 150°C. A thermal interface material (TIM) with a thermal conductivity of around 1-5 W/m-K is also recommended.

  • Yes, the BUX98A can be used in switching applications, but it's essential to ensure the transistor is properly driven and the switching frequency is within the recommended range (typically up to 100 kHz). The transistor's switching characteristics, such as rise and fall times, should be considered in the design.

  • To protect the BUX98A from ESD, it's recommended to use anti-static packaging, handling, and storage procedures. Additionally, ESD protection devices, such as TVS diodes or ESD protection arrays, can be used to protect the transistor from ESD events.
