AOB280L

Overview

The AOB280L is an N-Channel MOSFET from Alpha & Omega Semiconductor utilizing Trench technology. It features a Drain-Source Voltage (VDS) of 80 V and a continuous drain current (ID) of 140 A at TC=25°C. The static drain-source on-resistance (RDS(ON)) is less than 2.7 mΩ at VGS=10V for the TO-263 package, and less than 3.5 mΩ at VGS=6V. Key dynamic parameters include a total gate charge (Qg) of 160 nC typ at 10V, input capacitance (Ciss) of 11135 pF, and output capacitance (Coss) of 1315 pF. The device supports a maximum junction temperature of 175°C.

Feature Summary

Optimized Trench MOSFET technology designed to minimize both conduction and switching power losses through low RDS(ON), Ciss, and Coss values.
Validated for high-frequency switching performance with 100% Unclamped Inductive Switching (UIS) and Gate Resistance (Rg) testing.

Applications

Boost converters
Synchronous rectifiers
Consumer power supplies
Telecom power supplies
Industrial power supplies
LED backlighting

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact package type and pinout configuration. Ensure that the selected component meets the required thermal management specifications for the intended application environment. Confirm compliance with relevant environmental directives such as RoHS before finalizing procurement orders.

Selection Notes

Select this component based on the 80V voltage rating and 140A current capacity requirements. Evaluate the thermal resistance characteristics relative to the PCB layout and heatsinking strategy. Consider the gate charge and threshold voltage when designing the driver circuitry to ensure efficient switching transitions within the specified operating temperature range.

Part Context

The AOB280L belongs to the AOT/AOB series of N-Channel MOSFETs manufactured by Alpha & Omega Semiconductor. It is part of a product line optimized for high-efficiency power conversion applications requiring low on-resistance and robust switching capabilities in surface-mount packages like the TO-263.

Replacement Considerations

Cross-reference electrical parameters such as VDS, ID, and RDS(ON) with alternative suppliers. Verify pin compatibility and thermal characteristics if substituting with other 80V N-Channel MOSFETs.
