Product details
Overview
IRLR110TR from Vishay Siliconix is a logic-level N-channel power MOSFET in DPAK (TO-252) surface-mount package, rated for 100 V drain-source voltage, 4.3 A continuous drain current at TC = 25 °C, and 0.54 Ω RDS(on) at VGS = 5 V. It supports fast switching with 6.1 nC total gate charge and features repetitive avalanche capability for robustness in inductive load circuits such as DC-DC converters and motor drivers.
For engineers reviewing the IRLR110TR datasheet, IRLR110TR pinout, IRLR110TR application, or IRLR110TR equivalent, this device is selected for high-efficiency low-voltage switching where logic-level gate drive compatibility, thermal performance on PCB mount, and unclamped inductive switching reliability are critical design requirements.
Technical Context
This third-generation power MOSFET uses planar V-groove technology to achieve low RDS(on) while maintaining rugged dynamic dV/dt rating (5.5 V/ns) and specified avalanche energy (100 mJ single-pulse, 2.5 mJ repetitive). Its gate threshold voltage (1.0–2.0 V) ensures turn-on with standard 3.3 V or 5 V logic outputs.
The device integrates a body diode with 100–130 ns reverse recovery time and 0.50–0.65 μC Qrr, enabling use in synchronous rectification and freewheeling paths without external diodes in many medium-frequency (<100 kHz) topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - Supports input rails up to 80 V DC with safety margin in buck converters and battery-powered systems. |
| RDS(on) @ VGS = 5 V | 0.54 Ω - Enables <1.2 W conduction loss at 4.3 A, suitable for thermally constrained SMT layouts. |
| Qg | 6.1 nC - Low gate charge allows fast switching with modest gate driver current (e.g., 100 mA peak). |
| ID (continuous, TC = 25 °C) | 4.3 A - Rated for sustained current in heatsinked or copper-pour PCB applications. |
| EAS | 100 mJ - Withstands unclamped inductive energy spikes in relay drivers and solenoid controls without failure. |
| RthJA (PCB mount) | 50 °C/W - Achieves 2.5 W power dissipation on 1" FR-4 board, defining practical SMT thermal limits. |
| VGS(th) | 1.0–2.0 V - Ensures reliable enhancement-mode turn-on with 3.3 V microcontroller GPIOs. |
Pinout & Package
DPAK (TO-252) surface-mount package with exposed drain pad for thermal conduction and mechanical anchoring. Standard footprint per Vishay Application Note 826: 6.18 mm × 10.67 mm pad layout with 2.29 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control terminal | Receives logic-level voltage (≥2.0 V) to fully enhance channel; requires <100 nA leakage current handling. |
| Drain (D) | High-side switch node | Connected to PCB thermal pad; carries full load current and dissipates heat via copper pour or heatsink interface. |
| Source (S) | Reference/return path | Serves as local ground reference for gate drive; internal source inductance (7.5 nH) affects switching ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Turns on fully at VGS = 4.0 V (RDS(on) = 0.76 Ω), compatible with 3.3 V and 5 V digital controllers without level shifters. |
| Repetitive avalanche rated | Rated for 4.3 A repetitive avalanche current and 2.5 mJ energy, enabling reliable operation in flyback and boost converter primary switches. |
| Dynamic dV/dt immunity | 5.5 V/ns rating prevents false turn-on during high-slew transient events in noisy industrial environments. |
| Surface-mount (DPAK) | TO-252 outline enables automated assembly and efficient PCB thermal management using standard reflow profiles. |
| Low Qgd/Qg ratio | Qgd = 3.3 nC / Qg = 6.1 nC ≈ 54% - Reduces Miller plateau duration, improving hard-switching efficiency and EMI behavior. |

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 |
|---|---|---|---|
| IRLR7843PbF | 60 V VDS, 0.013 Ω RDS(on) @ 10 V, higher Qg (34 nC), same DPAK package | Better for high-current, low-voltage (<30 V) applications; unsuitable for 100 V bus designs | Select IRLR110TR when 100 V rating, lower gate charge, and logic-level drive are required over ultra-low RDS(on). |
| SiHLR110TR-GE3 | Identical electrical specs and DPAK package; Pb-free/halogen-free construction per JEDEC J-STD-609 | No functional difference; preferred for RoHS-compliant production with tighter material compliance | Choose SiHLR110TR-GE3 for new designs requiring halogen-free qualification; IRLR110TR remains valid for legacy or cost-sensitive builds. |
Compared with IRLR7843PbF, the IRLR110TR offers higher voltage tolerance and lower gate drive demand but higher on-resistance; versus SiHLR110TR-GE3, it shares identical performance while differing only in material compliance status and orderable part marking.

FAQ
What is the maximum continuous drain current for IRLR110TR at 100 °C case temperature?
The IRLR110TR supports 2.7 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package under sustained high-temperature operation and must be validated against actual PCB layout and ambient conditions in the final design.
Does IRLR110TR require a gate resistor for safe switching?
Yes - a gate resistor is recommended to control dI/dt and suppress ringing caused by the IRLR110TR's 7.5 nH internal source inductance and 3.3 nC Qgd. Typical values range from 10 Ω to 47 Ω depending on switching frequency and driver strength; values below 5 Ω may cause overshoot and EMI issues in hard-switched applications.
Is IRLR110TR suitable for use in a synchronous rectifier configuration?
The IRLR110TR can serve as a synchronous rectifier in low-frequency (<100 kHz) flyback or forward converters due to its 100–130 ns body diode reverse recovery time and 0.50–0.65 μC Qrr. However, its RDS(on) is higher than dedicated sync rectifiers, so efficiency gains are most pronounced at moderate loads and temperatures.
What is the thermal resistance from junction to ambient for IRLR110TR mounted on a standard PCB?
When mounted on a 1" square FR-4 PCB, the IRLR110TR exhibits RthJA = 50 °C/W. This value enables 2.5 W power dissipation at TA = 25 °C before reaching the 150 °C max junction temperature, assuming no additional heatsinking beyond standard copper pour.
Can IRLR110TR replace IRLU110 in an existing through-hole design?
No - IRLR110TR uses the DPAK (TO-252) surface-mount package, whereas IRLU110 uses the IPAK (TO-251) straight-lead through-hole package. The pinouts differ: IRLR110TR has G-D-S pin order with exposed drain pad; IRLU110 has G-D-S with vertical leads. Direct replacement requires PCB redesign and requalification.
