Product details
Overview
IRLIZ14GPBF from Vishay Siliconix is a logic-level N-channel power MOSFET in TO-220 FULLPAK package, rated for 60 V VDS, 8.0 A continuous drain current at TC = 25 °C, and 0.20 Ω RDS(on) at VGS = 5.0 V. It features 2.5 kVRMS isolation, 4.8 mm sink-to-lead creepage, and fast switching for industrial DC-DC converters and motor control.
For engineers reviewing the IRLIZ14GPBF datasheet, IRLIZ14GPBF pinout, IRLIZ14GPBF application, or IRLIZ14GPBF equivalent, this device is selected for high-reliability isolated switching where low gate drive voltage (≤5 V), avalanche ruggedness (39.5 mJ), and thermal performance (RthJC = 5.5 °C/W) are critical design requirements.
Technical Context
This MOSFET employs a third-generation silicon process optimized for low RDS(on) and fast switching with controlled dV/dt (4.5 V/ns peak diode recovery). Its isolated TO-220 FULLPAK construction eliminates external insulation hardware while maintaining 5.5 °C/W junction-to-case thermal resistance.
The device supports logic-level gate drive (VGS(th) = 1.0–2.0 V), delivers 3.6 S forward transconductance at 4.8 A, and exhibits 8.4 nC total gate charge - enabling efficient operation in 100 kHz–500 kHz SMPS topologies with minimal driver loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum blocking voltage for 48 V bus systems with safety margin |
| RDS(on) @ VGS = 5 V | 0.20 Ω - Enables ≤1.0 W conduction loss at 7 A, suitable for thermally constrained PCBs |
| Qg | 8.4 nC - Low gate charge allows fast turn-on with standard 1-A gate drivers |
| EAS | 39.5 mJ - Avalanche-rated for unclamped inductive switching in relay/motor drive circuits |
| RthJC | 5.5 °C/W - Enables >20 W power dissipation with moderate heatsinking (e.g., 25 °C ambient + 50 °C rise) |
| VGS(th) | 1.0–2.0 V - Guaranteed turn-on with 3.3 V or 5 V microcontroller GPIO without level-shifting |
| dV/dt rating | 4.5 V/ns - Robust against parasitic turn-on in noisy industrial environments |
Pinout & Package
IRLIZ14GPBF uses the TO-220 FULLPAK package: isolated plastic body with metal tab (drain-connected), 3-pin through-hole configuration, 15.87 mm length, 10.10 mm width, and 4.70 mm height. The molded compound provides 2.5 kVRMS isolation between drain and leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (exposed metal surface) | Drain (D) | Electrically connected to drain; serves as primary thermal path to heatsink; requires no insulating washer due to 2.5 kVRMS isolation |
| Lead 1 (left, when facing front label) | Source (S) | Low-side return path; connects to PCB ground plane; internal source bond wires minimize LS (7.5 nH) for clean switching |
| Lead 2 (center) | Gate (G) | High-impedance control input; accepts 0–5 V logic signals; Qgs = 3.5 nC ensures predictable Miller plateau timing |
| Lead 3 (right) | Source (S) | Second source connection for current sharing and reduced source inductance; paralleled internally with Lead 1 |
Key Features
| Feature | Design Value |
|---|---|
| Isolated TO-220 FULLPAK | Eliminates mica washers and mounting hardware - reduces BOM count and assembly cost in commercial-industrial power supplies |
| Logic-level gate drive | VGS(th) max 2.0 V ensures full enhancement with 3.3 V MCU outputs, removing need for gate driver ICs in low-power motor control |
| Low RDS(on) at 4 V | 0.28 Ω @ VGS = 4 V enables stable operation even with marginal gate drive voltage drop across long PCB traces |
| Fast switching with low Qgd | 6.0 nC gate-drain charge minimizes Miller-induced delay, supporting clean 500 kHz PWM in synchronous buck converters |
| Avalanche energy rating | 39.5 mJ single-pulse capability protects against inductive kickback in solenoid and relay driving without snubbers |
Applications

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 |
|---|---|---|---|
| IRFZ44NPBF | RDS(on) = 0.028 Ω @ 10 V (higher gate drive required); no isolation; TO-220 non-FULLPAK | Lacks 2.5 kVRMS isolation and creepage distance - requires external insulation in safety-critical designs | Select when higher current (49 A) and lower RDS(on) justify added insulation complexity and gate driver overhead |
| STP60NF06 | RDS(on) = 0.014 Ω @ 10 V; VDS = 60 V; Qg = 85 nC; no isolation; TO-220 | Higher gate charge increases driver loss and slows switching; no isolation necessitates insulating hardware | Prefer only in cost-sensitive, non-isolated 60 V applications where ultra-low RDS(on) outweighs gate drive and safety trade-offs |
Compared with IRLIZ14GPBF, IRFZ44NPBF offers lower on-resistance but demands 10 V gate drive and lacks isolation, while STP60NF06 trades significantly higher Qg and no isolation for marginal RDS(on) improvement - making IRLIZ14GPBF optimal for logic-driven, isolated, thermally constrained designs.

FAQ
What is the maximum continuous drain current for IRLIZ14GPBF at 100 °C case temperature?
The IRLIZ14GPBF supports 5.7 A continuous drain current at TC = 100 °C, derated linearly from 8.0 A at 25 °C using the 0.18 W/°C derating factor. This value is confirmed in the Absolute Maximum Ratings table and validated by thermal testing per Fig. 9 in the datasheet. Designers must ensure heatsink interface resistance and ambient conditions maintain TC ≤ 100 °C for sustained 5.7 A operation.
Does IRLIZ14GPBF require an insulating pad when mounted to a heatsink?
No, the IRLIZ14GPBF does not require an insulating pad. Its TO-220 FULLPAK package provides 2.5 kVRMS isolation between the drain-connected tab and all leads, with 4.8 mm sink-to-lead creepage distance. This eliminates the need for mica or silicone pads - verified in the Product Summary and Features sections of the Vishay datasheet S21-0978-Rev. D.
What is the typical gate-source threshold voltage range for IRLIZ14GPBF?
The IRLIZ14GPBF has a guaranteed gate-source threshold voltage (VGS(th)) range of 1.0 V to 2.0 V at TJ = 25 °C and ID = 250 μA. This logic-level specification ensures reliable turn-on with standard 3.3 V or 5 V digital outputs, as documented in the "SPECIFICATIONS" table under Static parameters in the official datasheet.
Can IRLIZ14GPBF be used in avalanche mode, and what is its rated energy?
Yes, the IRLIZ14GPBF is rated for single-pulse avalanche operation with EAS = 39.5 mJ at TC = 25 °C, tested under VDD = 25 V, L = 0.79 mH, RG = 25 Ω, and IAS = 10 A (per Note b and Fig. 12). This ruggedness supports inductive load switching without external snubbers in motor and relay drivers.
What is the drain-to-sink capacitance of IRLIZ14GPBF, and why does it matter?
The drain-to-sink capacitance (C) of IRLIZ14GPBF is 12 pF at f = 1.0 MHz, measured between the drain-connected tab and external heatsink. This low value minimizes capacitive coupling of high-frequency switching noise into the heatsink and adjacent circuits - critical for EMI-sensitive industrial applications, as specified in the Dynamic section of the datasheet.
