The RN1911FETE85LF is a digital transistor manufactured by Toshiba Semiconductor and Storage, featuring a single NPN configuration with built-in bias resistors. It operates within a collector-emitter voltage range of -50 V to 50 V and supports a continuous collector current of up to 100 mA. The device includes a typical input resistor of 4.7 kOhms with a resistor ratio of 1. Packaged in the compact SSM-3 surface-mount format, it offers a power dissipation capacity of 100 mW and functions reliably across an extended temperature range from -55°C to +150°C.
Verify the complete part number including the TE85L suffix to ensure correct packaging and lead-free compliance. Confirm RoHS status through official Toshiba documentation prior to integration. Check for specific distributor lot codes if traceability is required for your manufacturing process.
Select this component when a single NPN digital transistor with 4.7 kOhm base resistance is needed. Ensure the 100 mA collector current and 50 V voltage ratings exceed your circuit requirements. Consider the SSM-3 footprint constraints during PCB layout planning.
This part belongs to Toshiba's RN series of digital transistors, which combine BJTs with internal bias networks. The RN1911 variant specifically provides NPN polarity with a standard 4.7 kOhm input resistor, distinguishing it from other variants that may offer different resistor values or PNP configurations.
