Infineon BTS7040-2EPA Dual 40 mΩ PROFET+2 Smart High-Side Switch (PG-TSDSO-14)
The Infineon BTS7040-2EPA is a dual-channel, 12 V PROFET+2 smart high-side power switch designed for robust, efficient switching of resistive, inductive, and capacitive loads. Each channel integrates protection and diagnostic features to simplify design and increase system reliability. Packaged in a compact PG-TSDSO-14 and qualified to AEC‑Q100, the BTS7040-2EPA targets automotive body electronics as well as industrial load-driving applications where size, efficiency, and diagnostic coverage matter.
In one device, engineers get two high-side switches with approximately 40 mΩ typical on-resistance per channel, a wide 3 to 28 V operating range, and up to 3.5 A continuous load current per channel. These attributes make the Infineon BTS7040-2EPA a strong fit for lighting control, solenoids and valves, heaters, motors, and pumps—applications that demand reliable high-side switching with built-in protection.

Lifecycle, sourcing, and alternatives
- Lifecycle status: Active (per provided data). For the most current status, check the Infineon product page.
- Inventory: The provided snapshot indicates inventory quantity 0. Availability fluctuates; consult authorized distributors or Infineon’s channel partners for lead times.
- Replacements or pin-compatible alternatives: Not specified in the provided data. If you require higher/lower on-resistance, different current capability, or additional channels, explore Infineon’s PROFET+2 12V portfolio and use the manufacturer’s parametric search to identify candidates.
Practical sourcing guidance:
- Confirm AEC‑Q100 grade and any PPAP or documentation requirements with your quality team and supplier.
- Review packaging options and orderable part numbers on the product page to match your assembly flow.
- For second-source planning, verify electrical and functional compatibility carefully; do not assume pin-to-pin compatibility across different PROFET families without datasheet confirmation.
Design-in tips and integration checklist
These are general, non-numeric guidelines based on the device’s described capabilities. For quantitative limits, consult the datasheet.
- Power supply and decoupling: Place adequate local decoupling close to the device’s supply pins. Observe layout practices that minimize loop area and voltage overshoot on long harnesses.
- Load characteristics: Identify whether the load is resistive, inductive, or capacitive. For inductive loads, ensure your design respects the device’s protection behavior and clamping strategy as described by Infineon.
- Thermal planning: The typical on-resistance (~40 mΩ per channel) and load current (up to 3.5 A/channel) influence dissipation. Use copper pours and thermal vias as needed to manage junction temperature within the specified range (-40 to +150 °C).
- Diagnostics interface: Integrate the current sense/fault reporting into your ECU firmware. Establish thresholds and fault-handling routines to react to overcurrent or thermal events.
- Reverse battery and ESD: The device includes reverse battery protection and ESD robustness. Complement with system-level protections appropriate to the vehicle/industrial environment.
- Start-up and transients: Ensure power sequencing and transient behavior of the supply are within the operating voltage range (3 to 28 V). Validate cold-crank and load-dump scenarios against the datasheet recommendations.
- EMC considerations: Route high-current paths away from sensitive analog traces. Use ground referencing and filtering consistent with your system’s EMC plan.
