Product details
Overview
IRFIZ44GPbF from Vishay Siliconix is a 60 V, 30 A N-channel power MOSFET in TO-220 FULLPAK package, featuring 2.5 kVRMS isolation, 0.028 Ω RDS(on) at VGS = 10 V, and 175 °C maximum junction temperature-designed for high-reliability DC-DC converters, motor drives, and industrial power switching where thermal robustness and creepage safety are critical.
For engineers reviewing the IRFIZ44GPbF datasheet, IRFIZ44GPbF pinout, IRFIZ44GPbF application, or IRFIZ44GPbF equivalent, this device's isolated TO-220 FULLPAK construction, 95 nC total gate charge, avalanche-rated operation (100 mJ), and 4.8 mm sink-to-lead creepage distance are key selection criteria for insulated high-voltage switching designs.
Technical Context
This third-generation power MOSFET uses planar V-groove technology to achieve low RDS(on) while maintaining rugged unclamped inductive switching capability. Its dynamic dV/dt rating of 4.5 V/ns and body diode trr of 140–300 ns support fast, controlled turn-off in hard-switched topologies.
The TO-220 FULLPAK package integrates high-isolation molding compound (equivalent to 100 µm mica) directly over the drain tab, enabling direct heatsink mounting without insulating hardware-reducing thermal resistance to 3.1 °C/W (junction-to-case) and supporting continuous 30 A conduction at TC = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum blocking voltage compatible with 48 V bus systems and 24 V industrial rails. |
| RDS(on) | 0.028 Ω @ VGS = 10 V - Enables <1 W conduction loss at 18 A, reducing heatsink requirements. |
| ID (continuous) | 30 A @ TC = 25 °C - Supports high-current loads in compact PCB layouts with forced-air or passive heatsinking. |
| Qg / Qgd | 95 nC / 46 nC - Gate drive energy demand informs selection of gate drivers capable of ≥2 A peak sourcing/sinking. |
| EAS | 100 mJ - Rated single-pulse avalanche energy allows safe operation under inductive load switching faults. |
| TJ range | −55 to +175 °C - Enables deployment in under-hood automotive, industrial motor control, and high-ambient environments. |
| dV/dt rating | 4.5 V/ns - Confirmed immunity to false triggering during rapid voltage transients in noisy power stages. |
Pinout & Package
IRFIZ44GPbF uses the TO-220 FULLPAK package: isolated plastic body with integral drain tab, 3-pin vertical leadframe, 4.8 mm minimum creepage between drain tab and source/ground leads, and 3.1 °C/W junction-to-case thermal resistance. Mounting via single M3 screw (0.6 N·m torque) or clip directly to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | High-side power node / heat transfer surface | Electrically isolated metal tab serves as primary current path and thermal interface-requires no separate insulator when mounted to heatsink. |
| Source | Power return / reference node for gate drive | Low-inductance source connection enables stable gate control; internal LS = 7.5 nH limits di/dt-induced gate oscillation. |
| Gate | Control input / MOSFET turn-on/off signal | Threshold VGS(th) = 2.0–4.0 V ensures compatibility with standard 5 V and 10 V logic-level drivers; ±20 V max rating supports robust gate protection. |
Key Features
| Feature | Design Value |
|---|---|
| 2.5 kVRMS isolation (60 s, 60 Hz) | Eliminates need for external insulation hardware in commercial-industrial SMPS and motor inverters. |
| 175 °C maximum operating temperature | Enables extended lifetime in sealed enclosures or high-ambient environments without derating. |
| Low RthJC = 3.1 °C/W | Reduces thermal bottleneck between die and heatsink-supports higher power density than standard TO-220. |
| Body diode trr = 140–300 ns | Minimizes reverse recovery losses in synchronous rectification and freewheeling paths. |
| Dynamic dV/dt rating = 4.5 V/ns | Prevents spurious turn-on during high-slew-rate switching transitions in half-bridge configurations. |
Applications
| Industrial Motor Drives | DC-DC Converters |

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 |
|---|---|---|---|
| STP60NF06 | 60 V, 60 A, RDS(on) = 0.018 Ω, TO-220 non-isolated, no dV/dt rating specified | Lacks 2.5 kVRMS isolation and creepage compliance-requires external insulation and layout spacing | Preferred only where cost-per-amp is critical and isolation can be implemented externally. |
| IXTP50N10P | 100 V, 50 A, RDS(on) = 0.022 Ω, TO-220 FULLPAK, same isolation rating (2.5 kVRMS) | Higher voltage rating increases design margin but adds gate charge (110 nC) and cost | Chosen when system must withstand transient overvoltages beyond 60 V or future-proof for 72 V battery upgrades. |
Compared with STP60NF06 and IXTP50N10P, the IRFIZ44GPbF delivers optimal balance of isolation integrity, thermal performance, and 60 V system compatibility-making it the preferred choice for space-constrained, safety-critical 48 V industrial power stages where creepage and avalanche robustness are non-negotiable.

FAQ
What is the maximum continuous drain current rating for IRFIZ44GPbF at 100 °C case temperature?
The IRFIZ44GPbF supports 21 A continuous drain current at TC = 100 °C, per its absolute maximum ratings table. This derating reflects thermal limitations of the TO-220 FULLPAK package and ensures reliable operation within the 175 °C maximum junction temperature limit. Designers must verify heatsink performance to maintain TC ≤ 100 °C under full-load conditions. The IRFIZ44GPbF datasheet provides derating curves in Figure 9.
Does IRFIZ44GPbF require an external insulator when mounted to a heatsink?
No, the IRFIZ44GPbF does not require an external insulator when mounted to a heatsink. Its TO-220 FULLPAK package incorporates high-isolation molding compound providing 2.5 kVRMS isolation and 4.8 mm creepage distance between the drain tab and source/ground leads. This integrated isolation eliminates the need for mica washers or silicone pads in most commercial-industrial applications.
What is the typical gate threshold voltage range for IRFIZ44GPbF?
The IRFIZ44GPbF has a gate-source threshold voltage (VGS(th)) range of 2.0 V to 4.0 V at TJ = 25 °C and ID = 250 μA, per its specifications table. This logic-compatible threshold enables direct drive from microcontrollers and gate drivers operating at 3.3 V or 5 V, though 10 V gate drive is recommended to achieve the rated 0.028 Ω RDS(on). The IRFIZ44GPbF maintains stable threshold behavior up to 175 °C.
Can IRFIZ44GPbF be used in avalanche-mode switching applications?
Yes, the IRFIZ44GPbF is rated for single-pulse avalanche energy of 100 mJ under defined test conditions (VDD = 25 V, L = 129 μH, Rg = 25 Ω, IAS = 30 A), making it suitable for unclamped inductive switching in relay drivers, solenoid controls, and flyback snubbers. Repetitive avalanche operation is not guaranteed and requires careful thermal and electrical validation. The IRFIZ44GPbF datasheet specifies this rating in Section "Absolute Maximum Ratings".
What is the drain-to-sink capacitance value for IRFIZ44GPbF?
The drain-to-sink capacitance (C) of the IRFIZ44GPbF is 12 pF, measured at f = 1.0 MHz per the "Specifications" table. This low capacitance contributes to reduced common-mode noise coupling in isolated power stages and supports clean switching waveforms in high-frequency DC-DC converters. The value is confirmed in the dynamic parameter section of the IRFIZ44GPbF datasheet (Document Number: 91189).
