Product details
Overview
IRLR8726TRLPBF from Infineon Technologies is a 30V, 86A D-Pak N-channel HEXFET Power MOSFET optimized for high-frequency synchronous buck and isolated DC-DC converters. It delivers 4.0 mΩ RDS(on) at VGS = 10 V, 15 nC total gate charge, and 2.0 Ω gate resistance - enabling fast switching with low conduction loss in processor power and telecom rectification stages.
For engineers reviewing the IRLR8726TRLPBF datasheet, IRLR8726TRLPBF pinout, IRLR8726TRLPBF application, or IRLR8726TRLPBF equivalent, key selection criteria include its 30V VDS, ultra-low 4.0 mΩ on-resistance at 10V drive, 15nC Qg, avalanche-rated construction, and D-Pak thermal performance (RθJC = 2.0°C/W).
Technical Context
This MOSFET employs planar silicon HEXFET architecture with fully characterized unclamped inductive switching capability (EAS = 120 mJ at TJ = 25°C). Its gate threshold voltage (1.35–2.35 V) and negative temperature coefficient (−8.6 mV/°C) support stable parallel operation under thermal stress.
The device integrates a robust body diode with 24–36 ns reverse recovery time and 52–78 nC Qrr, enabling efficient synchronous rectification without external Schottky replacement in 1–2 MHz DC-DC topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage compatible with 24V input rails and transient overshoot in telecom/industrial supplies. |
| RDS(on) max @ 10V | 5.8 mΩ - Confirmed worst-case conduction loss at full rated current; typical value 4.0 mΩ enables <1.2W I²R loss at 25A DC. |
| Qg typ. | 15 nC - Low gate charge reduces driver power demand and supports >1 MHz switching with standard gate drivers. |
| ID @ TC = 25°C | 86 A - Continuous drain current rating defined at case temperature, validated for D-Pak mounting on 1-in² 2-oz copper. |
| RθJC | 2.0 °C/W - Junction-to-case thermal resistance enables direct heatsink attachment for high-power density designs. |
| EAS | 120 mJ - Single-pulse avalanche energy rating ensures robustness against inductive turn-off transients in synchronous rectifiers. |
Pinout & Package
IRLR8726TRLPBF uses the industry-standard D-Pak (TO-252AA) surface-mount package with exposed drain pad for thermal and electrical performance. Pin assignment is verified per Infineon's official package drawing and datasheet Figure 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Low-side reference node; connects to power ground plane; carries full load current in low-side switch configuration. |
| Pin 2 (Gate) | Control input | High-impedance MOS gate requiring <15 nC charge; sensitive to ESD; routed away from noisy power traces. |
| Pin 3 (Drain) | Power output / high-side return | Exposed copper pad on bottom surface; electrically and thermally connected to PCB copper pour for heat dissipation and low-inductance current path. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) at 4.5V VGS | Enables direct drive from 5V logic or PWM controllers without level-shifting; maintains <8 mΩ on-resistance in 5V-gate applications. |
| Fully characterized avalanche voltage/current | Guarantees safe operation under unclamped inductive switching events up to 120 mJ, eliminating need for external snubbers in synchronous rectifier designs. |
| Lead-free, RoHS-compliant construction | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1); qualified for reflow up to 260°C peak, supporting automated SMT assembly. |
| Low gate impedance (2.0–3.5 Ω) | Reduces gate ringing and EMI during hard switching; simplifies gate driver layout and damping resistor selection. |

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 |
|---|---|---|---|
| IRLR8721PbF | Same D-Pak package; higher RDS(on) (6.8 mΩ typ. @ 10V); lower ID (75A @ 25°C) | Suitable for lower-current (<60A) or cost-sensitive designs where 1.0 mΩ higher on-resistance is acceptable | Select when thermal margin exists and gate drive is constrained - same footprint but reduced performance headroom |
| STL220N3LLH6 | 30V, 220A, PowerFLAT 5x6; RDS(on) = 1.8 mΩ @ 10V; Qg = 39 nC; different package and pinout | Requires PCB redesign; suited for higher-current, lower-loss systems where space permits larger thermal pad | Choose only if upgrading to higher current density and accepting higher gate drive demand and layout change |
Compared with IRLR8726TRLPBF, IRLR8721PbF trades 1.8 mΩ higher RDS(on) for identical form factor, while STL220N3LLH6 offers half the on-resistance but doubles gate charge and mandates new layout - making IRLR8726TRLPBF optimal for balanced 80–100A D-Pak applications.

FAQ
Is IRLR8726TRLPBF suitable for 5V gate drive applications?
Yes. The device specifies RDS(on) ≤ 8.0 mΩ at VGS = 4.5 V and has a gate threshold voltage range of 1.35–2.35 V, ensuring reliable enhancement-mode operation with standard 5V logic-level drivers without requiring gate boosting.
What is the maximum continuous drain current at 100°C case temperature?
Per the Absolute Maximum Ratings table, ID @ TC = 100°C is 38 A. This derated value reflects thermal limitations of the D-Pak package under sustained high-temperature operation and must be validated with actual board-level thermal design.
Does IRLR8726TRLPBF include integrated ESD protection?
No. The device does not integrate dedicated ESD protection circuitry. Gate oxide is rated for ±20 V VGS, and handling requires standard MOSFET ESD precautions - including grounded workstations, ionized air, and gate-series resistors in production circuits.
Can IRLR8726TRLPBF replace IRLR8721PbF in existing designs?
Yes - it is a direct drop-in replacement with identical D-Pak footprint and pinout. IRLR8726TRLPBF offers lower RDS(on) (4.0 vs. 6.8 mΩ), higher ID (86 vs. 75 A), and identical gate characteristics, enabling immediate efficiency improvement without layout changes.
