Product details
Overview
IRFS4610TRRPBF from Infineon Technologies (formerly International Rectifier) is a 100V, 73A N-channel enhancement-mode HEXFET Power MOSFET in TO-220AB package, featuring 11 mΩ typical RDS(on), 90 nC total gate charge, and enhanced avalanche ruggedness. It serves as a high-current, hard-switched power switch in SMPS synchronous rectification, UPS output stages, and high-frequency DC-DC converters.
For engineers reviewing the IRFS4610TRRPBF datasheet, IRFS4610TRRPBF pinout, IRFS4610TRRPBF application, or IRFS4610TRRPBF equivalent, key selection criteria include its 100V VDSS, 73A continuous drain rating at 25°C, 0.77°C/W junction-to-case thermal resistance, body diode recovery time of 35–53 ns, and SOA-limited avalanche energy of 300 mJ.
Technical Context
This MOSFET employs planar stripe silicon technology optimized for low conduction loss and fast switching in hard-switched topologies. Its gate threshold voltage (2.0–4.0 V) enables robust 10 V gate drive compatibility, while its 3550 pF input capacitance and 36 nC Miller charge support controlled turn-off in high-dV/dt environments.
The integrated body diode exhibits 1.3 V forward voltage at 44 A and 44–66 nC reverse recovery charge, enabling reliable synchronous rectification without external Schottky supplementation. Avalanche capability is thermally limited to 300 mJ single-pulse with IAS = 44 A under defined test conditions (L = 0.39 mH, RG = 25 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - Maximum blocking voltage before avalanche onset; defines use in ≤65 V bus applications with margin. |
| RDS(on) typ. | 11 mΩ - Conduction loss of 58 W at 73 A (I²R), critical for thermal design in high-current SMPS outputs. |
| ID @ TC = 25°C | 73 A - Continuous current rating with heatsink; derates to 52 A at 100°C case temperature. |
| Qg | 90 nC - Total gate charge determining driver strength requirement; impacts switching loss at 100 kHz+. |
| trr | 35–53 ns - Body diode reverse recovery time; sets minimum dead-time in synchronous buck converters. |
| RθJC | 0.77 °C/W - Junction-to-case thermal resistance; enables direct heatsink mounting without thermal interface layer penalty. |
| EAS | 300 mJ - Single-pulse avalanche energy; supports unclamped inductive switching in UPS and motor drive snubbers. |
Pinout & Package
IRFS4610TRRPBF uses a TO-220AB package with standard three-terminal layout: Drain (D) connected to tab and pins 1 & 2, Source (S) on pin 3, Gate (G) on pin 1 (isolated from tab). The metal tab is electrically connected to the Drain, requiring insulated mounting hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab + Pins 1 & 2 | Drain (D) | Main high-side current path; thermally coupled to heatsink; must be isolated from PCB ground plane. |
| Pin 3 | Source (S) | Return path for load current; reference node for gate drive; connects to low-side switch or ground. |
| Pin 1 (isolated) | Gate (G) | Control terminal; requires ≥10 V for full enhancement; sensitive to ESD; routed away from noisy traces. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced dV/dt ruggedness | Rated for >1.3 V/ns transient immunity-reduces false turn-on risk in high-noise bridge-leg layouts. |
| Characterized avalanche SOA | 300 mJ single-pulse energy validated per JEDEC JESD24-11-enables reliable unclamped inductive switching. |
| Low Coss eff.(TR) | 380 pF effective output capacitance (time-related)-minimizes turn-on loss during zero-voltage switching transitions. |
| Optimized body diode dI/dt | Rated for 660 A/µs di/dt-supports fast commutation in synchronous rectifiers without oscillation. |
| Lead-free (PbF) construction | RoHS-compliant finish with matte tin plating-ensures solderability and long-term reliability in reflow processes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current 100V power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP75NF10 | Higher RDS(on) (12.5 mΩ typ.), lower Qg (72 nC), same TO-220AB package. | Slightly higher conduction loss but faster switching; less avalanche-rated (220 mJ). | Prefer when switching loss dominates and avalanche stress is minimal. |
| IXTH76N10L2 | Lower RDS(on) (9.5 mΩ typ.), higher Qg (125 nC), TO-247 package. | Better thermal performance (RθJC = 0.45 °C/W) but larger footprint and higher gate drive demand. | Choose for higher ambient temperatures or where heatsink space permits TO-247. |
Compared with STP75NF10 and IXTH76N10L2, IRFS4610TRRPBF offers the best balance of low RDS(on), moderate gate charge, and industry-leading 300 mJ avalanche rating in the TO-220AB form factor-making it optimal for cost-sensitive, high-reliability industrial SMPS designs.

FAQ
Is IRFS4610TRRPBF pin-compatible with IRFS4610PbF?
Yes-IRFS4610TRRPBF and IRFS4610PbF share identical TO-220AB pinout, electrical specifications, and thermal characteristics. The "T" suffix denotes tape-and-reel packaging, while "PbF" confirms lead-free finish; both are functionally interchangeable in PCB layout and circuit operation.
What is the maximum recommended gate drive voltage?
The absolute maximum gate-to-source voltage is ±20 V, but the device is fully enhanced at VGS = 10 V. Operating above 15 V provides no RDS(on) improvement and increases gate oxide stress risk; 10–12 V is the recommended range for reliable, efficient operation.
Can IRFS4610TRRPBF be used in surface-mount designs?
No-TO-220AB packages are explicitly not recommended for surface-mount applications per Infineon's package guidelines. The tab-to-pin creepage and thermal expansion mismatch with FR-4 PCBs risk solder joint fatigue and mechanical failure; through-hole mounting with heatsink is mandatory.
Does this MOSFET require a gate resistor for stability?
Yes-a gate resistor (typically 5–22 Ω) is required to dampen ringing caused by gate loop inductance and Miller capacitance. Without it, parasitic oscillation during switching can exceed VGS limits or cause shoot-through in half-bridge configurations, especially at >100 kHz.
