RN1605TE85LF

Overview

The RN1605TE85LF is a dual NPN pre-biased transistor manufactured by Toshiba Semiconductor and Storage. It integrates two NPN transistors with built-in bias resistors in an SOT-26 (SMD/SMT) package. Key electrical parameters include a maximum collector-emitter voltage of 50V, a continuous collector current of 100mA, and a power dissipation rating of 300mW. The typical input resistance is 2.2 kOhms, with a minimum DC current gain (hFE) of 80 at 10mA and 5V. The device features a saturation voltage of 300mV at 250µA base current and 5mA collector current.

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the full part number with distributor catalogs to avoid confusion with similar RN series variants that may have different resistor values or package types.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required for space-constrained designs. Ensure the 50V voltage rating and 100mA current capacity meet the circuit load requirements. Verify that the 2.2 kOhm typical input resistance aligns with the driving source impedance and desired switching speed characteristics for the specific application environment.

Part Context

This component belongs to the RN1605 series of digital transistors from Toshiba. It is part of a broader family of pre-biased transistors designed to simplify circuit design by replacing discrete resistors and transistors with single integrated packages. The TE85L suffix typically indicates specific packaging and environmental compliance attributes defined by the manufacturer.

Replacement Considerations

Direct substitutes within the same series include parts with identical pinouts and electrical characteristics but potentially different resistor values or packaging options. Verify compatibility with existing PCB footprints and thermal management requirements before substituting.
