Additional Details
The 2SC3736 is typically supplied in a small-signal package, such as SOT-23 or similar. The collector-base voltage (VCBO) is rated at 25V, the collector-emitter voltage (VCEO) at 20V, and the emitter-base voltage (VEBO) at 3V. The collector current (IC) is typically around 30mA. The transition frequency (fT) is usually around 8 GHz. The noise figure (NF) is typically very low, around 1 dB at 1 GHz. The operating temperature range is usually between -55°C and +150°C. The device's characteristics make it suitable for applications where preserving signal integrity and minimizing noise are critical.
