With a typical on-resistance of 11.5 mOhm and a maximum continuous output current of 8.5 A, it handles moderate loads like relays, solenoids, or LED modules in a 12 V automotive power distribution system. The 6 V to 18 V load supply range covers nominal 12 V systems with headroom for load-dump transients. ## Fault protection set — what's covered The device integrates fixed current limiting, open-load detection, over-temperature shutdown, over-voltage clamping, and undervoltage lockout (UVLO). This means a single BTS70121EPAXUMA1 replaces the discrete fuse + driver + diagnostic circuit in many automotive junction-box designs. ## Package and board-fit for the layout engineer The BTS70121EPAXUMA1 comes in a PG-TSDSO-14-22 package — a 14-lead TSSOP with an exposed pad (3.90 mm width).","metaTitle":"Infineon BTS70121EPAXUMA1 PROFET, 8.5A, 11.5mOhm","metaDescription":"Infineon BTS70121EPAXUMA1 automotive high-side switch, 8.5A max output, 11.5mOhm Rds(on), AEC-Q100, active production.
