概述

Description

IRF7304 is a power MOSFET from International Rectifier (now Infineon). It’s an N-channel enhancement-mode device used as a fast, high-current switch in power electronics.
Key points:
- Type: N-channel, enhancement mode
- Uses: DC-DC converters, motor drivers, high/low-side switches, H-bridges, general switching loads
- Specs vary by variant (Vds, Id, Rds(on), package). Typical features include low Rds(on) at Vgs around 10V, and a gate threshold in the low volts range.
- Common packages: options like TO-220/TO-263 (check the exact suffix)
- Design notes: drive the gate with adequate voltage (often 10V for low Rds(on)); include heat sinking and consider SOA (safe operating area) and avalanche energy; use a gate resistor and a pull-down to prevent floating gates; include appropriate flyback protection for inductive loads.
For precise numbers (Vds, Id, Rds(on), Qgs, Qgd, package), consult the exact datasheet suffix you’re using. If you share the package and voltage rating, I can summarize the exact specs.

Features

IRF7304 is an N-channel enhancement-mode power MOSFET. Typical features (varies by lot/variant):
- VDS: ~30 V; ID: ~4 A (continuous, depends on package)
- RDS(on): low (tens of milliohms typical)
- Gate: logic-level drive (fully on at ~4.5–5 V; VGS(th) ~ 1–2.5 V)
- Fast switching with reasonable gate charge
- Rugged body diode and avalanche capability
- Packages: common SMT options (DPAK TO-252, D2PAK TO-263) and Pb-free/RoHS-compliant variants
- Suitable for low-voltage, high-speed switching applications (buck regulators, motor drives, etc.)
Note: exact electrical numbers vary by variant; consult the latest datasheet for precise specs.

Package

IRF7304 is a power MOSFET in a TO‑220AB (through‑hole) package. Some variants are available in surface‑mount styles such as DPAK/TO‑263.

Pinout

IRF7304 is a 3-pin device (G, D, S) with the drain commonly tied to the package tab. It is an N-channel enhancement-mode power MOSFET used as a switching transistor in power electronics.

Manufacturer

- Manufacturer: International Rectifier (IR), now a brand of Infineon Technologies.
- What kind of company: A semiconductor company specializing in power electronics (power MOSFETs, IGBTs, drivers); Infineon is a German multinational semiconductor manufacturer.

Application

IRF7304 is a power N‑channel MOSFET used for fast switching in power electronics. Common applications include:
- Buck/boost/buck-boost DC-DC converters
- Motor drivers and PWM-controlled loads
- Solar/battery management and power-path circuits
- Load switches and hot-swap protection in switch-mode PSUs
- Power stages in inverters and UPS front ends

Equivalent

I can’t give exact equivalents without specs. Please share the IRF7304’s ratings (datasheet or key values): VDS, ID (continuous), RDS(on), package, and whether it’s N- or P-channel. With that, I’ll provide direct cross-part numbers from Vishay/Infineon/ON Semiconductor (via DigiKey/Mouser cross-ref).
