2N5551 Frequently Asked Questions (FAQ)

  • The 2N5551 can operate safely between -55°C to 150°C, but the recommended operating temperature range is -40°C to 125°C.

  • To ensure proper biasing, the base-emitter voltage (VBE) should be around 0.7V, and the collector-emitter voltage (VCE) should be around 1V to 2V. The base current (IB) should be limited to 5mA to 10mA.

  • The 2N5551 can handle a maximum collector current (IC) of 1A, and a maximum peak current (Ipk) of 2A.

  • To protect the 2N5551 from ESD, handle the device by the body, use an anti-static wrist strap or mat, and store the device in an anti-static bag or container.

  • Yes, the 2N5551 can be used in high-frequency switching applications up to 100 kHz, but the device's switching characteristics and power losses should be carefully considered.
