Product details

Pre-biased PNP — what the integrated resistors save you

The RN2105,LF(CT: The Toshiba RN2105 LF CT is a PNP pre-biased transistor in a SC-75 SOT-416 surface-mount package. It integrates a 2.2 kOhms base resistor (R1) and a 47 kOhms emitter-base resistor (R2), which set the turn-on threshold and provide a defined off-state, eliminating two external passives from the BOM. The 200 MHz transition frequency means it can handle signal-path switching up into the low RF range, not just DC load switching.

Active, ROHS3, and the SC-75 footprint

Maximum power dissipation is 100 mW, which sets the thermal budget for continuous operation.

Frequently asked questions

Is the RN2105 LF CT RoHS compliant?

Yes, it is listed as ROHS3 compliant.

What is the difference between RN2105 and RN2106?

The RN2106 uses different resistor values, which shifts the input threshold and bias conditions. Check the respective datasheets for the exact RN2106 resistor values to confirm fit for your drive circuit.
