BUX87P datasheet by Philips Semiconductors

BUX87P Frequently Asked Questions (FAQs)

• What is the maximum safe operating area (SOA) for the BUX87P?
  The SOA is not explicitly stated in the datasheet, but it's generally recommended to limit the collector-emitter voltage (Vce) to 60V and the collector current (Ic) to 5A to ensure safe operation.
• How do I handle thermal management for the BUX87P?
  The BUX87P has a thermal resistance (Rth) of 62°C/W. Ensure good heat sinking, use a heat sink with a thermal resistance of 10°C/W or less, and maintain a maximum junction temperature (Tj) of 150°C to prevent overheating.
• What is the recommended storage temperature range for the BUX87P?
  Store the BUX87P in a dry, cool place with a temperature range of -40°C to 100°C to prevent damage or degradation.
• Can I use the BUX87P in a switching application?
  Yes, the BUX87P is suitable for switching applications due to its high switching speed (tf = 10ns, trr = 20ns) and low saturation voltage (Vce(sat) = 1.5V). However, ensure proper design and layout to minimize switching losses and electromagnetic interference (EMI).
• How do I select the correct base resistor value for the BUX87P?
  Choose a base resistor value that limits the base current to 5mA or less, depending on the specific application. A general rule of thumb is to use a base resistor value of 1kΩ to 10kΩ.
