Product details

45 mOhm low-side switch for 12V/24V loads

The IPS031S is a single-channel low-side N-channel power switch from STMicroelectronics, designed for general-purpose on/off switching of resistive and inductive loads up to 35 V. Typical Rds(on) is 45 mOhm, and the switch can deliver up to 2.8 A continuous output current. It includes fixed current limiting and over-temperature fault protection, so it handles short circuits and thermal overload without external clamp diodes in most applications.

Parametric fit for automotive and industrial rails

The 35 V max load voltage covers 12 V and 24 V nominal systems with headroom for load-dump transients. The 2.8 A output at 45 mOhm typical Rds(on) means conduction losses stay under 0.35 W at full load — manageable with the D²Pak exposed tab soldered to a copper plane. Input is non-inverting with a simple on/off interface — no external Vcc supply required. The 1:1 input-to-output ratio means the gate is driven directly from the logic signal, simplifying the BOM for relay, solenoid, lamp, and motor pre-drive stages.

Frequently asked questions

Is IPS031S obsolete?

Yes, the IPS031S is listed as obsolete. It is no longer manufactured by STMicroelectronics.

What is the replacement for IPS031S?

No official replacement order code is recorded for the IPS031S. A parametric replacement must be evaluated based on the original socket requirements: low-side N-channel switch, 35 V max load, 2.8 A output, 45 mOhm typical Rds(on), D²Pak package, and -40°C to 150°C temperature range.

What are the specifications of IPS031S?

The IPS031S is a single low-side N-channel power switch with 45 mOhm typical Rds(on), 2.8 A max output current, 35 V max load voltage, non-inverting on/off input, and built-in current limiting and over-temperature protection.
