SQ2389CES-T1_BE3-VB Product details
Back to previous pageProduct introduction：
Still troubled by the large board area occupied by negative voltage power management and battery reverse protection circuits? VBsemi SQ2389CES-T1_BE3-VB offers a highly integrated solution! This SOT23-3 packaged P-MOSFET, despite its small size, can handle a continuous current of -3.6A with an on-resistance as low as 71mΩ (@10V), significantly reducing conduction losses compared to similar products. The Trench process provides faster switching response and lower gate charge, and the -40V withstand voltage easily handles battery reverse protection, load switches, and DC-DC auxiliary circuits, making it a "reliable guardian" for portable and industrial applications.
