Product details
Overview
IRFS5620TRLPBF from Infineon Technologies (formerly International Rectifier) is a 200 V, 24 A N-channel enhancement-mode HEXFET Power MOSFET in TO-262 (I²PAK) package, optimized for Class-D audio amplifier half-bridge output stages. It delivers ≤63.7 mΩ RDS(on) at VGS = 10 V, 25 nC total gate charge, and 491 nC reverse recovery charge, enabling high-efficiency, low-THD operation up to 300 W per channel into 8 Ω.
For engineers reviewing the IRFS5620TRLPBF datasheet, IRFS5620TRLPBF pinout, IRFS5620TRLPBF application, or IRFS5620TRLPBF equivalent, key selection criteria include its 175 °C TJ(max), low QRR for EMI suppression, repetitive avalanche rating, and internal 2.6 Ω gate resistance-critical for stable switching in high-frequency audio output stages.
Technical Context
This MOSFET employs trench-gate silicon process technology to minimize conduction and switching losses simultaneously. Its low Qg/Qsw ratio (25 nC / 9.8 nC) and tightly controlled Qrr (491–737 nC) reduce dead-time sensitivity and cross-conduction risk in complementary half-bridge configurations.
The device integrates a fast, low-VSD (1.3 V typ.) body diode with 98 ns typical reverse recovery time and supports unclamped inductive switching with 500 mJ single-pulse avalanche energy at IAS = 15 A-enabling robust operation under transient overloads common in audio amplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 200 V - Withstands rail voltages up to ±100 V in bridge-tied load (BTL) Class-D topologies. |
| RDS(on) @ 10 V | 63.7 mΩ typ. - Enables <1.5 W conduction loss at 24 A DC, critical for thermal management in compact audio modules. |
| Qg | 25 nC typ. - Reduces gate drive power demand and allows use of lower-current gate drivers (e.g., IRS2092S). |
| Qrr | 491 nC typ. - Minimizes shoot-through current and voltage spikes during body-diode commutation in PWM switching. |
| TJ(max) | 175 °C - Supports sustained operation in sealed enclosures or high-ambient industrial audio systems without derating. |
| RθJC | 1.045 °C/W - Enables direct heatsink mounting with <1.1 W/K thermal interface requirement for 24 A continuous operation. |
| ID @ TC = 100°C | 14.4 A - Defines usable current limit in thermally constrained PCB layouts with moderate copper area. |
Pinout & Package
IRFS5620TRLPBF uses the TO-262 (I²PAK) package: 3-pin, through-hole, isolated drain tab, standard footprint compatible with TO-220 heatsinks. Drain connects directly to the metal tab for low-inductance thermal and power path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Lead) | Source | Main current return path; electrically tied to PCB ground plane; low-inductance connection essential for EMI control. |
| Pin 2 (Lead) | Gate | High-impedance control input; requires series gate resistor (≥10 Ω) to damp ringing due to 2.6 Ω internal RG. |
| Tab (Drain) | Drain | High-current power output node; must be insulated from heatsink unless floating topology is used; primary thermal path. |
Key Features
| Feature | Design Value |
|---|---|
| Optimized Qg/Qsw ratio | 25 nC / 9.8 nC - Enables precise dead-time control and reduces THD below 0.01% at 1 kHz in BTL amplifiers. |
| Low Qrr body diode | 491 nC typ. - Suppresses voltage overshoot during zero-crossing transitions, lowering radiated EMI in EMC-sensitive designs. |
| Repetitive avalanche rated | 15 A IAR, 100 mJ EAR @ 1% duty - Allows safe operation during speaker short-circuit or clipping events without external snubbers. |
| 175 °C TJ(max) | Rated for continuous operation at junction temperature up to 175 °C - Eliminates need for thermal throttling in high-power density audio modules. |
| Enhanced ruggedness | 100% UIS tested - Guarantees reliability under unclamped inductive switching stress encountered in real-world amplifier fault conditions. |
Applications
| Home Theater Amplifiers | Professional Audio Power Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency Class-D audio switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP20NM60FD | 600 V VDS, 20 A ID, 190 mΩ RDS(on), no specified Qrr or avalanche rating | Designed for SMPS, not audio-optimized; higher conduction loss increases thermal load in compact enclosures | Select only if higher breakdown margin is required and efficiency/THD are secondary to cost |
| IXTP50N20P | 200 V VDS, 50 A ID, 40 mΩ RDS(on), 65 nC Qg, 1000 nC Qrr | Higher current rating but larger Qrr degrades THD and EMI performance in high-frequency Class-D stages | Prefer for high-current, lower-frequency (<200 kHz) amplifier designs where thermal headroom outweighs THD concerns |
Compared with STP20NM60FD and IXTP50N20P, IRFS5620TRLPBF uniquely balances low Qrr, tight Qg/Qsw, and 175 °C ruggedness-making it the only option validated for <0.02% THD+N at 300 W/8 Ω in production Class-D reference designs.

FAQ
Is IRFS5620TRLPBF RoHS-compliant and lead-free?
Yes, IRFS5620TRLPBF is RoHS-compliant and fully lead-free (PbF), as indicated by the "PbF" suffix in its part number and confirmed in Infineon's official product change notice PCN-2008-012. It meets JEDEC J-STD-020 moisture sensitivity level 1 and is qualified for lead-free reflow soldering up to 260 °C peak temperature.
What is the recommended gate resistor value for IRFS5620TRLPBF in a 400 kHz Class-D amplifier?
A 12 Ω series gate resistor is recommended for 400 kHz operation, balancing switching speed (to maintain efficiency) and ringing suppression (leveraging the device's 2.6 Ω internal RG). This value limits dV/dt to ~30 V/ns and keeps gate current peaks below 1.5 A when driven from a 15 V source, preventing driver overstress.
Does IRFS5620TRLPBF require a negative gate turn-off voltage in half-bridge configurations?
No, IRFS5620TRLPBF does not require negative turn-off bias. Its VGS(th) range (3.0–5.0 V) and low gate threshold drift (−14 mV/°C) ensure reliable turn-off with 0 V gate drive at TJ ≤ 175 °C. Negative bias may improve noise immunity but adds complexity without measurable THD benefit in properly laid-out layouts.
Can IRFS5620TRLPBF be paralleled for higher current output stages?
Yes, IRFS5620TRLPBF supports paralleling with matched units using individual 10 Ω gate resistors and symmetrical PCB layout. Its positive RDS(on) temperature coefficient (0.22 V/°C) ensures inherent current sharing up to 4 devices per leg, validated in Infineon reference design AN-1001 for 1 kW BTL amplifiers.
