Frequently Asked Questions
Is BTS50085-1TMA obsolete?
Yes. Infineon's official product page labels BTS50085-1TMA as END OF LIFE and lists the orderable product BTS500851TMAATMA1 as discontinued.
Is BTS50085-1TMA a 24V-only switch?
No. It belongs to the Classic PROFET 24V family, but its datasheet operating range is 5.0V to 58V. Infineon's current product page recommends 5.5V to 58V. This makes it suitable for nominal 24V systems with substantial supply variation, subject to all datasheet limits.
Can BTS50085-1TMA continuously switch 44A?
Not without validating the exact thermal conditions. The 44A figure is a typical ISO load-current value with the case held at 85°C and a defined voltage drop. The nominal value on Infineon's specified PCB is 11.1A at 85°C ambient. Actual capability depends on the thermal design and load profile.
What is the BTS50085-1TMA package?
Infineon's datasheet specifies the PG-TO220-7-4 seven-lead SMD power package. Some sales databases call the mechanical style TO-263-7 or D²PAK-7. Use the official package drawing and full OPN to verify compatibility.
Does BTS50085-1TMA provide load-current diagnostics?
Yes. The IS pin supplies a diagnostic sense current proportional to load current. The product summary gives a nominal IL ratio of 13,000. The same current-sense path supports open-load detection, subject to the datasheet conditions and external sense resistor.
Is BTT6010-1ERA a drop-in replacement?
No. Infineon has suggested BTT6010-1ERA as a newer functional alternative, but it uses a different PG-TDSO-14 exposed-pad package. A PCB and system redesign may be required, and electrical, diagnostic, thermal and transient requirements must be requalified.
