Product details

Active production — 10 mOhm low-side switch for harsh environments

The BTS3256DAUMA1 is an Infineon HITFET® single-channel low-side switch with a typical Rds(on) of 10 mOhm, rated for continuous output current up to 7.5 A. Sourcing is handled per RFQ — confirm current availability and pricing at quote time.

Parametric deep-dive — Rds(on), protection, and package

At 10 mOhm typical, the BTS3256DAUMA1 dissipates roughly 0.56 W at 7.5 A — the PG-TO252-5-11 package with its exposed tab can handle that with proper board copper. Compare this to the sibling BTS142DATMA1 which lists 23 mOhm typical; the BTS3256DAUMA1 cuts conduction losses by more than half for the same load current. Integrated fault protection includes fixed current limiting, over-temperature shutdown, over-voltage clamping, and undervoltage lockout. The input is non-inverting with a simple On/Off interface — no external Vcc supply required. The Auto Restart feature lets the output recover after a fault clears, which is useful for lamp or solenoid loads that see inrush.

Infineon continues to produce the HITFET® series.

Frequently asked questions

What is the closest functional alternative to BTS3256DAUMA1?

Within the same HITFET® family, the BTS142DATMA1 is a single-channel low-side switch with a higher typical Rds(on) of 23 mOhm and a lower max output current of 4.6 A. The BTS3256DAUMA1 offers lower conduction losses and higher current capability, but both share the same input type, fault protection set, and temperature range.
