MUN5231DW1T1G

MUN5231DW1T1G Description

The MUN5231DW1T1G from onsemi is a dual NPN pre-biased transistor array in a compact SOT-363 surface-mount package. Designed for low-power switching and amplification, it integrates two transistors with 2.2kΩ base-emitter resistors (R1/R2), simplifying circuit design by eliminating external biasing components. With a collector-emitter breakdown voltage (Vce) of 50V and a maximum collector current (Ic) of 100mA, it balances efficiency and robustness. The device features a low Vce saturation of 250mV (at 5mA Ib, 10mA Ic), ensuring minimal power loss in switching applications. Compliant with ROHS3 and REACH, it is ideal for modern, eco-conscious designs.

MUN5231DW1T1G Features

• Pre-Biased Design: Integrated 2.2kΩ resistors reduce external component count, saving board space and cost.
