Product details

High-side switch for 12 V automotive loads

It drives resistive, inductive, and lamp loads up to 25 A continuous from an 8 V to 18 V supply rail.

With a typical on-resistance of 3.9 mOhm, this switch dissipates roughly 2.4 W at 25 A (I²R). That heat flows through the TO-263-7 (D²Pak) tab to the PCB copper plane; the junction temperature rating of 150 °C sets the derating curve for real-world ambient conditions underhood or in an engine bay.

Integrated fault protections for harsh environments

The device integrates over-temperature shutdown, over-voltage clamp, reverse battery protection, and short-circuit current limiting. These protections are essential for an automotive power distribution node where load dump, reverse polarity, and wiring faults are expected events, not anomalies.

Infineon lists the BTS500251TADATMA1 as obsolete.

Frequently asked questions

Is BTS500251TADATMA1 obsolete and what is the direct replacement?

Yes, Infineon lists the BTS500251TADATMA1 as obsolete. No official direct replacement is recorded. For a pin-compatible alternative, review the BTS50025 base product number family; the BTS500251TADATMA1 itself is the base variant. Sourcing is through independent distribution against an RFQ.

Where can I buy BTS500251TADATMA1 at the best price?

The BTS500251TADATMA1 is obsolete and no longer stocked by franchised distributors. Submit a request for current market pricing.

Does BTS500251TADATMA1 have reverse polarity and over-temperature protection?

Yes. The BTS500251TADATMA1 integrates over-temperature shutdown, over-voltage clamp, reverse battery protection, and short-circuit current limiting as standard fault protections.
