Product details

Gate charge and switching — fast enough for most DC-DC

Total gate charge is 5.4 nC at 4.5 V, and input capacitance is 724 pF at 25 V drain bias. The 2.7 W package power limit is the real constraint in continuous high-frequency switching; for a load-switch or low-duty-cycle application it's fine, but a sustained 10 A at high frequency will need a bigger package or heatsinking.

Product status is Active, and the part is ROHS3 compliant. No end-of-life notice or last-time-buy on record. The STripFET™ V series is a current-generation ST process, so supply through the independent channel is stable.

Frequently asked questions

What is the closest pin-compatible alternative to STS8DN3LLH5 in this component family?

No official second-source or pin-compatible alternate is listed in the available records. The STripFET™ V series includes other dual N-channel parts in SO-8, but pin compatibility varies by gate-drive and current rating — verify the specific order code against your layout.

What compliance documentation does this brand provide for STS8DN3LLH5 (RoHS, REACH, UL, IEC)?

The STS8DN3LLH5 is ROHS3 compliant per the listing. No REACH, UL, or IEC documentation is stated in the available records.
