The AOTS40B65H1 is a 650V Alpha IGBT manufactured by Alpha & Omega Semiconductor. It offers a continuous collector current of 40A at TC=100°C and 80A at TC=25°C, with a maximum VCE(sat) of 1.9V at TJ=25°C. The device features a short-circuit withstand time of 5μs and operates within a junction temperature range of -55°C to 175°C. Available in TO-220 tube packaging, it utilizes advanced Alpha IGBT technology for high switching speed and low turn-off loss.
Verify the specific ordering suffix to confirm package type and reel/tube configuration. Ensure the component meets consumer market qualification standards as critical life support applications are not authorized. Confirm thermal management requirements align with the specified junction-to-case resistance values during system design.
Select based on required voltage rating of 650V and current handling capabilities up to 80A at lower case temperatures. Consider the 5μs short-circuit withstand time for protection circuitry design. Evaluate thermal performance using the provided transient thermal impedance curves for pulsed operation scenarios.
This component belongs to the Alpha IGBT family from Alpha & Omega Semiconductor. It is designed for general purpose power switching applications requiring fast recovery and low conduction losses. The part is distinct from similar models like AOKS40B65H1 primarily by its specific package and marking configuration.
Direct substitutes include the AOKS40B65H1 variant which shares identical electrical specifications but may differ in physical package or marking details. Verify pinout compatibility and thermal characteristics before implementation.
