BUX10 datasheet by STMicroelectronics

BUX10 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the BUX10?
  The recommended operating voltage range for the BUX10 is 10V to 30V, with a maximum voltage rating of 40V.
• How do I ensure the BUX10 is properly biased for optimal performance?
  To ensure proper biasing, connect the base of the transistor to a voltage divider network that sets the base voltage to around 2-3V, and ensure the collector-emitter voltage is at least 5V.
• What is the maximum current rating for the BUX10?
  The maximum collector current rating for the BUX10 is 10A, and the maximum peak current rating is 15A.
• How do I protect the BUX10 from overheating?
  To prevent overheating, ensure proper heat sinking, use a heat sink with a thermal resistance of 5°C/W or less, and maintain a maximum junction temperature of 150°C.
• Can I use the BUX10 as a switch in a high-frequency application?
  While the BUX10 can be used as a switch, it's not recommended for high-frequency applications (>100kHz) due to its relatively high capacitance and inductance. Consider using a faster-switching transistor or a dedicated high-frequency switch.
