Product details

Overview

IRF7465 from International Rectifier is a 150V, 1.9A N-channel enhancement-mode MOSFET in SO-8 package, optimized for high-frequency DC-DC converters. It features 0.28Ω R_DS(on) at V_GS = 10V, 10nC total gate charge, and 40mJ single-pulse avalanche energy - enabling robust switching in compact offline SMPS and point-of-load regulators.

For engineers reviewing the IRF7465 datasheet, IRF7465 pinout, IRF7465 application, or IRF7465 equivalent, key selection criteria include its low Q_gd/Q_g ratio (0.5–0.75), fully characterized C_oss(eff) = 76pF, body diode t_rr = 62–93ns, and SO-8 thermal resistance R_θJA = 50°C/W - all critical for ZVS/ZCS design and EMI-limited layouts.

Technical Context

This HEXFET power MOSFET uses planar vertical DMOS structure with optimized cell pitch and trench-free gate oxide to balance conduction loss and switching speed. Its gate threshold voltage (3.0–5.5V) ensures reliable turn-on with standard 5V/10V logic drivers while maintaining noise immunity.

The device integrates a fully rated intrinsic body diode with V_SD = 1.3V at I_S = 1.14A and controlled reverse recovery (Q_rr = 160–240nC), making it suitable for synchronous rectification and flyback snubberless topologies where diode conduction occurs during dead time.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	150V - supports 110VAC input-derived 120V bus designs with 20% margin
R_DS(on) max	0.28Ω @ V_GS = 10V - limits I²R loss to ≤0.6W at 1.5A continuous drain current
Q_g max	15nC - enables <100ns turn-on with 150Ω gate resistor at 10V drive
E_AS	40mJ - withstands unclamped inductive switching events up to 1.9A peak current
C_oss(eff)	76pF - defines hard-switching loss component and impacts resonant tank tuning
t_rr	62–93ns - determines minimum dead-time requirement in half-bridge configurations
R_θJA	50°C/W - requires ≥1.5cm² copper pour for 2.5W dissipation at T_A = 70°C

Pinout & Package

IRF7465 is housed in a standard SO-8 surface-mount package (JEDEC MS-012AA), with exposed drain pads on pins 1–4 and 5–8 for enhanced thermal conduction. The package supports lead-free reflow per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1–4, 5–8 (D)	Drain	Parallel-connected high-side switch node; electrically common; primary heat path to PCB
6 (G)	Gate	Control terminal requiring <15nC charge; sensitive to ringing above 30V absolute rating
7–8 (S)	Source	Power return reference; ties to driver ground; body diode anode

Key Features

Feature	Design Value
Low Q_gd/Q_g ratio	0.5–0.75 - reduces Miller-induced switching delay and improves dV/dt immunity
Fully characterized C_oss(eff)	76pF over full V_DS range - enables accurate calculation of capacitive switching loss
Specified avalanche capability	40mJ single-pulse - eliminates need for external clamping in inductive load transients
Body diode t_rr & Q_rr	62–93ns / 160–240nC - allows predictable timing for synchronous rectifier control

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 150V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP16NF15	R_DS(on) = 0.22Ω (lower), Q_g = 18nC (higher), TO-220 package	Requires heatsink; unsuitable for space-constrained SMT designs	Prefer when thermal budget allows discrete mounting and lower conduction loss dominates
SiHFL018	R_DS(on) = 0.25Ω, Q_g = 12nC, same SO-8 footprint	Higher V_GS(th) (4–6V); less compatible with 5V gate drivers	Prefer when gate drive is ≥12V and lower gate charge is prioritized over threshold margin

Compared with STP16NF15 and SiHFL018, IRF7465 offers optimal trade-off between SO-8 mountability, 5V-compatible V_GS(th), and balanced Q_g/R_DS(on) - making it uniquely suited for high-density, medium-power SMPS where board area and driver simplicity are constrained.

Manufacturer

International Rectifier (now part of Infineon Technologies) was a pioneer in power MOSFET and IGBT design, known for HEXFET technology and high-reliability industrial-grade components.

The IRF7465 belongs to the HEXFET Power MOSFET product line, engineered specifically for high-frequency switched-mode power supplies where low gate charge, controlled diode recovery, and avalanche ruggedness are essential.

FAQ

Is IRF7465 suitable for 5V gate drive?

Yes - its gate threshold voltage is specified from 3.0V to 5.5V, and R_DS(on) is guaranteed at V_GS = 10V but remains functional down to 4.5V. At 5V drive, typical R_DS(on) increases to ~0.45Ω, which is acceptable for low-duty-cycle or low-current applications like auxiliary supplies.

What is the maximum recommended PCB copper area for thermal performance?

For operation at full 2.5W power dissipation with T_A = 70°C, a minimum of 1.5cm² of 2oz copper connected to the drain pads (pins 1–4 and 5–8) is required to maintain junction temperature below 150°C, based on R_θJA = 50°C/W and measured thermal resistance data from IR Application Note AN-994.

Does IRF7465 have a qualified automotive grade variant?

No - the IRF7465PbF is qualified only for consumer and industrial applications per the datasheet. It does not meet AEC-Q101 requirements. For automotive use, consider Infineon's OptiMOS™ 5 series (e.g., BSC014N04LS) with identical SO-8 footprint and AEC-Q101 qualification.

Can IRF7465 replace IRF7478 in existing designs?

No - although both are SO-8 N-channel MOSFETs, IRF7478 has V_DSS = 200V and R_DS(on) = 0.18Ω, while IRF7465 is rated for 150V and 0.28Ω. Substitution would compromise voltage margin in 200V-class circuits and increase conduction loss; no pin-to-pin compatibility is claimed by manufacturer.
