Product details

3.7 mOhm Rds(on) at 50 A — conduction loss floor

The on-resistance of 3.7 mOhm at Vgs=10 V and 50 A sets the conduction-loss baseline for a 40 V power stage — at 50 A the dissipation is roughly 9.25 W, which the 119 W Tc rating can handle with an adequate heatsink.

Gate drive and switching budget

Total gate charge is 100 nC at Vgs=10 V, with an input capacitance of 5550 pF at Vds=25 V. A 10 V drive voltage is specified for the minimum Rds(on); the gate is rated ±20 V max. For a 100 kHz switching frequency, the average gate-drive current is 100 nC × 100 kHz = 10 mA — well within a standard gate-driver IC's capability, but the peak current during the Miller plateau requires a driver with at least 2 A peak output to keep switching edges clean.

It is ROHS3 compliant.

Frequently asked questions

What is the N0412N-S19-AY datasheet and pinout?

Design engineers need to validate fit and electrical compatibility before incorporating into a circuit.

Where can I buy N0412N-S19-AY and what is the price?

Sourcing buyers need immediate purchasing information to fill a BOM line and compare distributor pricing.

What are the exact equivalent or alternative parts for N0412N-S19-AY?

Both sourcing and design use equivalents for second-sourcing or when the primary part is out of stock or obsolete.

Is N0412N-S19-AY obsolete or end-of-life?

Maintenance techs and brokers need to know lifecycle stage to plan for replacement or avoid discontinued parts.

How does N0412N-S19-AY compare to IRF1405Z?

Comparison with popular alternatives helps engineers make informed trade-offs on Rds(on), gate charge, and cost.
