Overview
The BTS282ZAKSA1 is a single-channel N-channel enhancement mode MOSFET from the Speed TEMPFET family, designed for automotive low-side switching applications. It features a maximum drain-source voltage of 49 V and a typical on-state resistance of 6.5 mΩ at 10 V gate drive. The device supports a nominal load current of 52 A and includes an integrated potential-free temperature sensor with thyristor characteristics for overtemperature protection. It operates within a junction temperature range of -40 °C to +175 °C and offers fast switching capabilities up to 1 MHz.
Feature Summary
- Integrated potential-free temperature sensor with thyristor characteristics for direct thermal monitoring
- Built-in overtemperature protection mechanism to safeguard against excessive heat
- High current pinning capability for robust performance under heavy loads
- Avalanche rated design allowing for repetitive avalanche energy handling
Applications
- Automotive low-side power switching for 12 V systems
- Industrial load control requiring temperature-protected switching
- Driving inductive loads such as solenoids and relays
Procurement Notes
Verify the specific ordering code suffix to confirm package lead length and pin configuration. Ensure the component meets the required automotive qualification standards for your application environment. Cross-reference datasheet version numbers to confirm electrical parameter consistency before finalizing procurement specifications.
Selection Notes
Select this component when a single-channel low-side switch with integrated thermal sensing is required. The high nominal current rating makes it suitable for heavy-duty automotive loads. Consider the P-TO220-7 package constraints for thermal management and PCB layout requirements during the design phase.
Part Context
This part belongs to Infineon's Speed TEMPFET family, established for nearly three decades in the market. These devices are specifically engineered as temperature-protected low-side switches for 12 V and 24 V automotive and industrial environments. The family provides basic protection via an integrated sensor available on external pins.
Replacement Considerations
Infineon recommends transitioning to Classic HITFET™ or HITFET™ + families for new designs, as the TEMPFET™ series is no longer intended for new development. Verify pin compatibility and thermal characteristics when considering alternative smart low-side switches.
