The RN1107,LF(CT is a single NPN pre-biased bipolar junction transistor manufactured by Toshiba Semiconductor and Storage. It integrates a bias resistor network within an SSM (SC-75/SOT-416) surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a transition frequency of 250 MHz. The device features a base resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 47 kOhms. DC current gain is specified at a minimum of 80 at 10 mA and 5 V, with a maximum saturation voltage of 300 mV under standard test conditions.
Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly line standards.
Select this component when a compact NPN digital transistor with a 10 kOhm base resistance is required. Ensure the application operates within the 50 V collector-emitter voltage limit and 100 mA current threshold. Verify that the 250 MHz transition frequency meets the switching speed requirements of the target circuit design.
This part belongs to the RN11xx series of NPN pre-biased transistors from Toshiba. These devices are designed as direct replacements for discrete resistor-transistor networks, offering space savings in portable electronics and computer peripheral interfaces where board real estate is constrained.
Public confirmed substitutes include DDTC144GE-7-F, DTC114TET1G, and DTC114TETL.
