2SC1685 Frequently Asked Questions (FAQs)

  • The recommended PCB footprint for the 2SC1685 is a standard TO-92 package with a minimum pad size of 1.5mm x 1.5mm and a thermal pad size of 2.5mm x 2.5mm.
  • Yes, the 2SC1685 can be used in switching applications, but it's not recommended for high-frequency switching (>100kHz) due to its relatively high transition frequency (ft) of 150MHz. It's more suitable for low-frequency switching applications or linear amplification.
  • To ensure the 2SC1685 operates within its SOA, you should limit the collector-emitter voltage (Vce) to ≤ 50V, collector current (Ic) to ≤ 1A, and power dissipation (Pd) to ≤ 625mW. You should also ensure the device is properly heat-sinked and the ambient temperature is within the recommended range.
  • The recommended storage temperature for the 2SC1685 is -40°C to +125°C. Storage outside this range may affect the device's reliability and performance.
  • The 2SC1685 is rated for operation up to 150°C, but its performance may degrade at high temperatures. You should derate the device's power dissipation and ensure proper heat-sinking to prevent thermal runaway.
