概述
Description
IRFZ34NS is an N-channel, enhancement-mode power MOSFET from the IRF family.
Key points:
- VDS: 55 V; ID: about 16–17 A (continuous)
- RDS(on): ~0.04 Ω typical at VGS = 10 V (higher at lower temps)
- Gate threshold: ~2–4 V; must drive with ~10 V for low RDS(on)
- VGS max: ±20 V
- Packaging: variants exist (NS suffix relates to a specific package/series; check the exact datasheet for TO-220 or surface-mount options)
- Not a true logic-level device at 5 V; good conduction requires higher gate drive
- Use with proper heat sinking and gate protection; review SOA for switching/transient requirements
Applications: switching elements in DC-DC converters, motor drivers, power switches, H-bridges.
Note: always consult the exact datasheet for your specific NS variant to confirm packaging and electrical ratings.
