2SD2142KT146 Description

Short technical summary and product information.

The 2SD2142KT146 is an NPN Darlington transistor from ROHM Semiconductor. It features a maximum collector-emitter voltage of 30V, a maximum collector current of 300mA, and a maximum power dissipation of 200mW. The DC current gain (hFE) is a minimum of 10000 at 100mA collector current and 5V collector-emitter voltage. The Vce saturation voltage is a maximum of 1.5V at 100µA base current and 100mA collector current. The transition frequency is typically 200MHz. The device is designed for surface mount assembly and is available in the SMT3 package, which is equivalent to TO-236-3, SC-59, and SOT-23-3. The operating junction temperature can reach up to 150°C. This transistor is suitable for general purpose switching and amplification applications requiring high current gain.
