Infineon BTT6030-1ERA: A High-Side Power Switch for Robust Automotive and Industrial Applications
In the demanding environments of modern automotive systems and industrial automation, reliable power switching is paramount. The Infineon BTT6030-1ERA stands out as a premier high-side power switch engineered specifically to meet these rigorous challenges. As part of Infineon's PROFET™ (Protected MOSFET) family, this device integrates advanced protection features, diagnostic capabilities, and robust performance into a single, compact package.
The core of the BTT6030-1ERA is a vertical N-channel power MOSFET with a very low typical on-state resistance (RDS(on)) of just 5 mΩ. This exceptionally low resistance is crucial for minimizing conduction losses and improving overall system efficiency, which is especially vital in battery-operated automotive applications where every watt of power saved counts. It is capable of handling a continuous output current of up to 28 A, making it suitable for driving a wide array of loads, from motors and heaters to LEDs and solenoids.
What truly sets this device apart is its comprehensive suite of integrated protection and diagnostic functions. It is designed to be inherently robust against the electrical hazards common in harsh environments. Key protections include:
Overload and short-circuit protection
Over-temperature shutdown with a restart mechanism

Over-voltage protection (including load-dump resilience)
Reverse battery protection (down to -40 V)
Ground loss and supply line protection
Furthermore, the BTT6030-1ERA provides precise diagnostic feedback via a dedicated status pin. It can report multiple states including normal operation, overtemperature pre-warning, open-load, and short-circuit to ground, enabling sophisticated system monitoring and predictive maintenance. This level of intelligence allows designers to build safer and more reliable systems that can preemptively address potential faults.
Housed in a PG-TO-252-5-11 (DPAK-5) package, the device offers excellent thermal performance while maintaining a small footprint. Its AEC-Q100 qualification ensures it meets the stringent reliability standards required for automotive applications, from body control modules and powertrain systems to interior and comfort electronics. Its robustness also makes it an ideal choice for 24V industrial systems controlling actuators, valves, and pumps.
ICGOOODFIND: The Infineon BTT6030-1ERA is a highly integrated and intelligent high-side switch that delivers superior performance, ruggedness, and diagnostic intelligence. It simplifies design, enhances system reliability, and provides the peace of mind necessary for mission-critical automotive and industrial applications.
