Product details

60 V, 70 A N-channel in DPAK — STripFET™ III generation

The 60 V Vdss gives a 20 % derating margin against a typical 48 V bus, which is standard practice for reliable operation. The 70 A continuous drain rating is package-limited; the actual current the device can carry in your design depends on the PCB copper area and ambient cooling — the 110 W maximum power dissipation figure is the thermal ceiling to work from. The 10.5 mOhm Rds(on) at 10 V gate drive means conduction losses stay under 1 W at 10 A load, but note that the threshold voltage can be as high as 4 V at 250 µA, so a logic-level gate drive below 5 V may not fully enhance the channel.

Lifecycle status — obsolete, with sourcing path

Frequently asked questions

Is STD70N6F3 obsolete?

Knowing the lifecycle status prevents design-in of a part that may become unavailable, and sourcing buyers need to plan for last-time buys or alternatives.

What is the direct replacement for STD70N6F3?

Sourcing buyers and maintenance technicians need a drop-in substitute to avoid redesign or prolonged downtime.

What is the price of STD70N6F3?

Pricing directly impacts BOM cost; transactional buyers need current price to make purchase decisions.

What are the specifications of STD70N6F3?

Design engineers must validate electrical and thermal parameters to ensure fit in their circuit.

Can I use STD70N10F4 as a replacement for STD70N6F3?

Buyers often compare cross-references; confirming compatibility of a specific alternative saves research time and reduces risk.

Where can I buy STD70N6F3?

Transactional intent is highest when a buyer is ready to purchase; pointing to distributors with stock closes the sale.
