Overview
The BTS247Z is an automotive low-side temperature-protected switch belonging to the TEMPFET family. It features a single channel with a maximum drain-source voltage of 55 V and a nominal load current of 12 A, capable of handling up to 19 A per channel. The device offers a maximum power dissipation of 120 W and a maximum on-resistance of 18 mΩ at Tj = 150°C. It provides EAS capability of 1300 mJ, with turn-on and turn-off times of 0.07 µs each. Operating within a temperature range of -40 °C to 175 °C, it utilizes latch protection strategies and is available in SMT packages.
Feature Summary
- Integrated temperature sensor for overtemperature protection
- Fast switching capabilities suitable for high-frequency applications
- Robust avalanche energy handling capability
Applications
- 12 V automotive systems
- 24 V automotive systems
- Industrial applications requiring low-side switching
Procurement Notes
Verify component authenticity through official Infineon channels or authorized distributors. Confirm package type and suffix codes match design requirements. Check for end-of-life status as this family is not intended for new designs. Ensure compliance with RoHS standards and functional safety requirements relevant to the target application environment.
Selection Notes
Select based on required load current and thermal management needs. Consider that the TEMPFET family is legacy; evaluate Classic HITFET or HITFET+ families for new designs. Verify package compatibility and ensure sufficient heat sinking for 120 W dissipation. Confirm voltage ratings align with system bus voltage.
Part Context
Part of the TEMPFET family, established for nearly 30 years for basic temperature-protected switching. This family serves as a foundational solution but is superseded by advanced smart switches for new developments. It remains relevant for maintenance and existing product lines requiring simple, robust low-side control.
Replacement Considerations
For new designs, consider upgrading to Classic HITFET or HITFET+ families which offer enhanced diagnostic features and lower on-resistance. Direct pin-to-pin replacements may vary; verify electrical parameters and package dimensions carefully before substitution.
