Single FETs, MOSFETs datasheet and documents for AOI452A

AOI452A

Single FETs, MOSFETs Overview

The AOI452A is an N-Channel SDMOSTM Power Transistor fabricated with trench technology, designed for PWM and load switching applications. It features a Drain-Source Voltage (VDS) of 25V and a Gate-Source Voltage (VGS) of ±20V. The device offers a maximum continuous drain current (ID) of 36A at 25°C case temperature and 16A at 70°C ambient temperature. At VGS=10V, the on-resistance (RDS(ON)) is typically 6mΩ, rising to 9mΩ at 125°C junction temperature. Total gate charge (Qg) is 17nC at 10V and 11nC at 4.5V. The component operates within a junction temperature range of -55°C to 175°C.

Single FETs, MOSFETs Feature Summary

Utilizes SDMOSTM trench technology to combine low on-resistance with controlled switching behavior.
Features 100% UIS (Unclamped Inductive Switching) testing for enhanced reliability in inductive loads.
Designed for high efficiency in general-purpose applications through optimized gate charge characteristics.

Single FETs, MOSFETs Procurement Notes

Verify the specific package type and tape/reel specifications against the manufacturer's latest documentation before ordering. Confirm that the RoHS compliance status matches project requirements. Ensure the supplier provides traceability data consistent with Alpha & Omega Semiconductor Inc. standards. Check for any recent product change notices or lifecycle updates regarding this part number.

Single FETs, MOSFETs Selection Notes

Select the AOI452A when a 25V rating is sufficient and low RDS(ON) is critical for efficiency. Consider the thermal resistance values for heatsinking requirements in your PCB layout. Evaluate the gate charge parameters against your driver capabilities to ensure adequate switching speeds. Verify that the TO-251A/IPAK package fits your mechanical constraints.

Single FETs, MOSFETs Part Context

This component belongs to the SDMOSTM family from Alpha & Omega Semiconductor Inc., utilizing trench MOSFET architecture. It is distinct from higher voltage variants like the AOD950A70 (700V) or lower voltage arrays like the AOTE21115C (20V dual P-channel). The AOI452A specifically targets low-voltage, high-current switching needs.

Single FETs, MOSFETs Replacement Considerations
