Overview
The BTS282ZE3230AKSA2 is an automotive low-side smart power switch belonging to the TEMPFE family. It integrates a single N-channel MOSFET with diagnostic capabilities and temperature sensing in a TO-220-7 package. Key electrical parameters include a drain-source voltage of 49 V, a nominal load current of 52 A, and a maximum on-state resistance of 6.5 mΩ at 150°C. The device supports high avalanche energy of 2000 mJ, features turn-on and turn-off times of 0.1 µs and 0.16 µs respectively, and operates within a junction temperature range of -40°C to 175°C.
Feature Summary
- Integrated temperature sensor for thermal monitoring
- High avalanche energy capability for robust operation
- Low on-state resistance for efficient power handling
Applications
- Automotive lighting systems
- Motor control applications
- Solenoid driving circuits
Procurement Notes
Verify the specific ordering suffix AKSA2 against official Infineon documentation to confirm exact packaging and reel specifications. Ensure compatibility with existing PCB footprints for the PG-TO220-7-12 package. Confirm that the component meets all required automotive qualification standards for the intended application environment before finalizing procurement plans.
Selection Notes
Select this component when a single-channel low-side switch with integrated thermal protection is required. The TEMPFE technology provides direct temperature feedback, simplifying system design by eliminating external sensors. Consider the 49 V rating and 52 A current capacity to ensure adequate headroom for the specific load requirements and operating conditions.
Part Context
This part belongs to Infineon's HITFET and TEMPFE families of automotive low-side smart switches. These devices are designed for high-reliability automotive applications, combining power switching with intelligent diagnostics. The TEMPFE variant specifically includes a temperature sensor output, allowing the control unit to monitor the switch's thermal state directly.
Replacement Considerations
Check for alternative part numbers within the same TEMPFE family or other HITFET series that offer compatible pinouts and electrical characteristics. Verify that any substitute maintains the required avalanche energy rating and diagnostic functionality.
