RN2111ACT(TPL3)

Overview

The RN2111ACT(TPL3) is a PNP digital transistor manufactured by Toshiba Semiconductor and Storage, featuring built-in bias resistors within an SC-70 surface-mount package. It integrates a single PNP bipolar junction transistor with two internal resistors: R1 (base resistor) of 10 kΩ and R2 (emitter resistor) of 10 kΩ. The device supports a maximum collector-emitter voltage (Vceo) of 50 V and a continuous collector current (Ic) of 100 mA. Key electrical parameters include a DC current gain (hFE) minimum of 50 at Ic=10mA, Vce=5V, and a saturation voltage (Vce(sat)) maximum of 300 mV at Ib=250µA, Ic=5mA. The transition frequency is rated at 200 MHz, with a power dissipation of 100 mW.

Procurement Notes

Verify the specific ordering suffix TPL3 against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or Toshiba Semiconductor and Storage sales representatives prior to procurement.

Selection Notes

Select this component when a PNP configuration with equal 10kΩ bias resistors is required. Ensure the 50V voltage rating and 100mA current capacity meet the load requirements. Compare hFE and Vce(sat) specifications against alternative pre-biased transistors if tighter gain or lower saturation performance is needed for the specific application.
