IMH21T110 Description

Short technical summary and product information.

The IMH21T110 is a dual NPN pre-biased digital transistor from ROHM Semiconductor, integrating two DTC614T chips in a single SMT6 package. Each transistor includes a built-in 10kΩ input resistor, simplifying circuit design by eliminating external resistor components.

 

Key electrical characteristics include a maximum collector-emitter voltage of 20V, a maximum collector current of 600mA, and a DC current gain (hFE) ranging from 820 to 2700 at Vce=5V and Ic=50mA. The low saturation voltage, typically 40mV at Ic/Ib=50mA/2.5mA, makes this device well-suited for muting circuits and other low-voltage switching applications.

 

The device is housed in a compact SC-74 (SOT-457) surface-mount package with a supplier device package designation of SMT6. It is rated for a total power dissipation of 300mW (200mW per element) and operates over a storage temperature range of -55°C to 150°C. The transition frequency is 150MHz, and the output ON resistance is typically 0.9Ω.
