The BTS110E3045ANTMA1 is a single-channel low-side smart power switch from Infineon's Classic HITFET family, designed for automotive and industrial applications. It integrates an N-channel MOSFET with control and protection circuitry in a PG-TO220-3-5 package. The device features a maximum drain-source voltage of 40V and supports continuous load currents up to 10A. Key electrical characteristics include a typical on-resistance of 28mΩ at 25°C and a short-circuit current limit of approximately 60A. It operates within a junction temperature range of -40°C to 150°C.
Verify the specific suffix ANTMA1 against official Infineon documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage levels not exceeding 40V. Confirm that the required short-circuit withstand time aligns with application safety margins. Check for RoHS compliance status relevant to your manufacturing region requirements.
Select this component when a single-channel low-side switch with integrated diagnostics is required. It is suitable for replacing relays or discrete MOSFETs with external protection. Consider the 28mΩ on-resistance for conduction loss calculations. Ensure the PCB layout supports the thermal performance of the TO-220 package for high-current operation.
This part belongs to Infineon's Classic HITFET series, which offers proven reliability for 12V automotive systems. The series is characterized by high robustness against transient loads and ESD. It serves as a standard solution for basic load switching tasks where diagnostic feedback is beneficial but complex multi-channel integration is unnecessary.
Direct substitutes may include other BTS11x variants with compatible pinouts and electrical ratings. Verify that any replacement maintains the same diagnostic functionality and package dimensions. Cross-reference with Infineon's official substitution guides for confirmed equivalents.
