The Alpha & Omega Semiconductor Inc. AOI452A is an N-Channel Power MOSFET from the SDMOS™ series, packaged in a TO-251A (IPAK) through-hole configuration. This device offers a continuous drain current of 55A at 25°C (Tc) and a drain-source breakdown voltage of 25V. With a maximum on-resistance of 7.3mOhm at 20A and 10V gate-source voltage, it features low conduction losses. The AOI452A is suitable for applications requiring high current density and efficient switching, commonly found in power management, automotive, and industrial control systems. Its operating temperature range is -55°C to 175°C (TJ), with a maximum power dissipation of 50W at 25°C (Tc). Key electrical parameters include a gate charge (Qg) of 26 nC (max) at 10V and input capacitance (Ciss) of 1450 pF (max) at 12.5V.
