It switches resistive, inductive, and lamp loads on the high side, with each of the eight outputs independently controlled via a parallel interface. The switch uses N-channel output transistors, so no external Vcc supply is needed — the load voltage powers the gate drive internally. Rated for load voltages from 11V to 45V, it covers 12V and 24V industrial and automotive rails. The 150 mOhm typical Rds(on) is specified at 25°C; at 125°C junction temperature expect roughly double that figure — budget for the hot resistance when sizing the PCB copper for thermal dissipation, especially with multiple channels loaded. Built-in fault protection includes fixed current limiting, over-temperature shutdown, and over-voltage clamping. These features eliminate the need for external clamp diodes or resettable fuses on each channel for basic fault coverage, simplifying the BOM and board layout. ## Package and thermal considerations for the PG-DSO-36-26 The ITS42008SBDAUMA1 comes in a 36-BSSOP (0.433\", 11.00mm Width) exposed-pad package, supplier code PG-DSO-36-26. Surface-mount assembly requires a thermal pad on the PCB with adequate via stitching to the ground plane to pull heat away from the die. With eight channels conducting simultaneously, the total power dissipation can exceed 5W — the exposed pad is not optional, it is the primary thermal path. Junction temperature range is -25°C to 125°C. The -25°C low end is adequate for most industrial and automotive interior applications, but designs that must start below -25°C (cold-crank or arctic outdoor) should verify the switch's behaviour at the lower extreme against the application note. ## Active lifecycle and sourcing posture The ITS42008SBDAUMA1 is listed as Active with ROHS3 compliance. No last-time-buy or end-of-life notice is in effect, so the part is suitable for both new designs and ongoing production.","metaTitle":"Infineon ITS42008SBDAUMA1 High-Side Power Switch, 8-Ch","metaDescription":"Infineon ITS42008SBDAUMA1 8-channel high-side power switch, 150mOhm Rds(on), 11V-45V load, fault protection.
