Product details
Overview
IRF7495TR from Infineon Technologies (formerly International Rectifier) is a 100V, 7.3A N-channel HEXFET Power MOSFET in SO-8 package, optimized for high-frequency DC-DC converters. It features 22 mΩ RDS(on) at VGS = 10 V, 11.7 nC Qgd, 240 pF effective output capacitance (Coss,eff), and integrated body diode with 42 ns trr - enabling efficient synchronous rectification in isolated flyback and active clamp forward topologies.
For engineers reviewing the IRF7495TR datasheet, IRF7495TR pinout, IRF7495TR application, or IRF7495TR equivalent, key selection criteria include low gate-to-drain charge for reduced switching loss, fully characterized Coss and avalanche ratings for hard-switched converter design, and SO-8 thermal performance under PCB-mount conditions.
Technical Context
This MOSFET employs planar vertical DMOS technology with optimized charge distribution to minimize Qgd/Qg ratio (≈34%), supporting fast, low-loss turn-off in high-frequency PWM stages. Its 100 V VDSS rating and 4.4 A IAS single-pulse avalanche capability allow operation in clamped inductive switching circuits up to 150 °C junction temperature.
The device integrates a robust body diode with 1.3 V VSD at 4.4 A and 73 nC Qrr, enabling reliable freewheeling in synchronous buck and half-bridge configurations without external Schottky supplementation. Coss,eff = 240 pF is validated per AN-1001 for accurate snubberless soft-switching timing prediction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - supports 48 V input DC-DC systems with ≥2× voltage margin against transients |
| RDS(on) max | 22 mΩ @ VGS = 10 V - limits conduction loss to ≤1.2 W at 7.3 A continuous drain current |
| Qgd | 11.7 nC - reduces Miller-induced switching delay and enables <10 ns turn-off delay (td(off)) |
| Coss,eff | 240 pF - enables accurate zero-voltage switching (ZVS) timing in resonant converters |
| trr | 42 ns - ensures clean body-diode commutation in synchronous rectifiers up to 500 kHz |
| PD @ TA = 25°C | 58 W - achievable with 1-inch² copper pad; derates linearly at 0.02 W/°C above 25°C |
| RθJA | 50 °C/W - defines thermal rise under standard JEDEC PCB mount; RθJL = 20 °C/W to drain lead |
Pinout & Package
IRF7495TR is housed in a standard SO-8 surface-mount package (JEDEC MS-012, EIA-481 compliant), with exposed drain paddle for enhanced thermal conduction. Pin 1 is gate (G), pins 2–4 and 6–8 are parallel-connected drains (D), and pins 5 and 7 are sources (S). The package supports automated reflow assembly and delivers 20 °C/W junction-to-lead thermal resistance when soldered to a full drain pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Control terminal; requires ≤±20 V drive; 200 nA leakage at VGS = ±20 V |
| 2, 3, 4, 6, 8 | Drain (D) | High-side switch node; all pins internally bonded to common drain metallization |
| 5, 7 | Source (S) | Power return path; dual-source configuration lowers source inductance for high-dI/dt operation |
Key Features
| Feature | Design Value |
|---|---|
| Low Qgd/Qg ratio | 34% - minimizes Miller plateau duration and improves controllability in hard-switched SMPS |
| Fully characterized Coss | 240 pF effective value - enables precise snubberless ZVS timing in LLC and phase-shifted full-bridge designs |
| Specified avalanche energy | 250 mJ single-pulse EAS @ IAS = 4.4 A - supports unclamped inductive switching in active-clamp topologies |
| Body diode trr & Qrr | 42 ns / 73 nC - enables synchronous rectification without cross-conduction risk in 300–500 kHz converters |
Applications
| Isolated Flyback Converter | Active Clamp Forward Converter |
|---|---|
Use Scenario: Primary-side switch in 24–48 V input, 12 V/5 A isolated flyback for industrial power supplies. IC Role / Device Role / Timing Role: High-side switching element operating at 300–500 kHz with ZVS-assisted turn-on.

IC Role / Device Role / Timing Role: Fast-switching upper transistor with body diode reverse recovery managed via gate timing. Use Value: 42 ns trr and 73 nC Qrr enable tight dead-time control, reducing shoot-through risk and improving light-load efficiency. | Use Scenario: Low-side switch in 24 V H-bridge for 100 W BLDC motor control in factory automation. IC Role / Device Role / Timing Role: Recirculation path during PWM off-time using integrated body diode. Use Value: Dual-source pins (pins 5 & 7) lower source loop inductance, suppressing voltage overshoot during 100 A/µs current reversal. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP10NK100ZFP | 100 V, 10 A, RDS(on) = 220 mΩ, TO-220FP package, higher RDS(on), no Coss,eff spec | Lower frequency (<100 kHz), higher conduction loss, unsuitable for ZVS designs | Prefer only where SO-8 footprint is not required and thermal mass outweighs switching loss |
| SiR872DP | 100 V, 7.3 A, RDS(on) = 20 mΩ, SO-8, Qgd = 10.2 nC, Coss,eff = 210 pF | Near-identical specs but tighter Qgd tolerance and lower Crss; optimized for 1 MHz+ operation | Preferred for >600 kHz designs where gate drive strength and Miller immunity are critical |
Compared with STP10NK100ZFP, IRF7495TR delivers 5× lower switching loss in high-frequency converters; versus SiR872DP, it trades marginally higher Qgd for broader avalanche ruggedness and field-proven reliability in industrial 24–48 V systems.

FAQ
What is the maximum continuous drain current for IRF7495TR at 100°C ambient temperature?
The maximum continuous drain current is 4.6 A at TA = 100°C with PCB mount, as specified in the Absolute Maximum Ratings table. This reflects thermal derating from the 7.3 A rating at 25°C, constrained by RθJA = 50 °C/W and maximum junction temperature of 150°C.
Does IRF7495TR support gate drive from 5 V logic-level controllers?
No - IRF7495TR has a gate threshold voltage range of 2.0–4.0 V but requires ≥10 V VGS to achieve its rated 22 mΩ RDS(on). At 5 V, RDS(on) rises significantly (>100 mΩ), increasing conduction loss; a dedicated 10–15 V gate driver is required for full performance.
How is the effective output capacitance (Coss,eff) measured and why does it matter?
Coss,eff = 240 pF is derived from the energy stored in Coss during VDS rise from 0 to 80% of VDSS, per Application Note AN-1001. It matters because it directly determines the time required for ZVS turn-on in resonant converters - unlike static Coss, it reflects actual switching behavior under real operating conditions.
Can IRF7495TR be used in parallel configurations?
Yes - its positive RDS(on) temperature coefficient (0.10 V/°C ∆VBRDSS/∆TJ) and matched SO-8 layout support current sharing. However, gate drive layout must balance trace inductance and resistance; use individual 6.2 Ω gate resistors (per datasheet test condition) and symmetrical PCB routing to avoid dynamic imbalance.
