That Rds(on) figure, measured at 25°C, sets the conduction loss at 0.29 W at full load — low enough to avoid a heatsink in many automotive and industrial solenoid or lamp-drive applications, provided the copper pad on the D2PAK tab is sized for the thermal budget. ## Integrated fault protection cuts external BOM The switch includes fixed current limiting and over-temperature shutdown, so no external sense resistor or thermal watchdog IC is needed. The input-to-output ratio is 1:1 with a non-inverting On/Off interface, and no Vcc supply is required — the gate drive is self-biased from the load voltage up to 35 V max. ## D2PAK package and 150°C junction — built for harsh environments That 150°C ceiling qualifies it for under-hood automotive and high-ambient industrial enclosures where the ambient may reach 85°C or more. Infineon lists the IPS0151S as Obsolete.","metaTitle":"IPS0151S Low-Side Switch, 20 mOhm, 3.8 A, D2PAK","metaDescription":"IPS0151S low-side N-channel power switch, 20 mOhm typ Rds(on), 3.8 A output, D2PAK.
