Product details
Overview
IRFIZ48GPBF from Vishay Siliconix is a 60 V, 37 A N-channel power MOSFET in TO-220 FULLPAK package with isolated tab, 2.5 kVRMS isolation rating, 0.018 Ω RDS(on) at VGS = 10 V, and 175 °C maximum junction temperature-designed for high-reliability DC-DC converters, motor drive half-bridges, and industrial SMPS where thermal robustness and creepage safety are critical.
For engineers reviewing the IRFIZ48GPBF datasheet, IRFIZ48GPBF pinout, IRFIZ48GPBF application, or IRFIZ48GPBF equivalent, this device's verified 4.8 mm sink-to-lead creepage, low 3.0 °C/W junction-to-case thermal resistance, and unclamped avalanche energy rating of 100 mJ support safe operation in mains-connected power stages and isolated gate-drive topologies.
Technical Context
This third-generation power MOSFET integrates an isolated TO-220 FULLPAK package with internal molding compound providing 2.5 kVRMS isolation-equivalent to a 100 µm mica barrier-eliminating external insulators in commercial-industrial designs. Its dynamic dV/dt rating of 4.5 V/ns and body diode reverse recovery time (trr) of 120–180 ns enable stable switching in hard-switched converters.
The device features low gate charge (Qg = 110 nC), split into Qgs = 29 nC and Qgd = 36 nC, supporting efficient gate driving at moderate frequencies. Its RDS(on) exhibits +0.060 V/°C VDS temperature coefficient and remains stable up to 175 °C, enabling predictable conduction loss across wide thermal ranges.
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 with margin. |
| RDS(on) | 0.018 Ω @ VGS = 10 V - Enables ≤1.8 W conduction loss at 10 A continuous drain current. |
| ID (TC = 25 °C) | 37 A - Sustains full-load current without derating when mounted on adequately sized heatsink. |
| Qg / Qgs / Qgd | 110 / 29 / 36 nC - Gate drive energy optimized for standard 12 V gate drivers with <250 ns rise/fall times. |
| RthJC | 3.0 °C/W - Enables direct thermal path from die to heatsink via isolated tab, reducing junction temperature rise by ~110 °C/W vs. standard TO-220. |
| EAS | 100 mJ - Withstands single-pulse inductive energy events common in relay/snubber-free motor control. |
| trr / Qrr | 120–180 ns / 0.50–0.80 µC - Body diode recovery behavior supports synchronous rectification and freewheeling in buck/boost topologies. |
Pinout & Package
IRFIZ48GPBF uses the TO-220 FULLPAK package: isolated plastic housing with metal tab electrically connected to drain, 3-pin through-hole configuration (G-D-S), 4.8 mm minimum creepage between sink and leads, and 2.5 kVRMS isolation rated for 60 s at 60 Hz.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control terminal | Receives 10 V logic-level gate drive; threshold voltage 2.0–4.0 V enables compatibility with microcontroller GPIO or dedicated gate drivers. |
| Drain (D) | High-side switch node | Connected to internal tab; serves as primary high-voltage output node and thermal interface to heatsink. |
| Source (S) | Power return / reference | Low-side connection point; forms common reference for gate drive and current sensing; not isolated from PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Isolated TO-220 FULLPAK | Eliminates need for mica washers or silicone pads-reduces assembly cost and thermal interface resistance in AC/DC front-ends. |
| 2.5 kVRMS isolation | Validated per IEC 60950/62368 for reinforced insulation in secondary-side power switches and isolated DC-DC controllers. |
| 175 °C TJ max | Supports operation in sealed enclosures or high-ambient environments without forced air cooling. |
| Dynamic dV/dt rating | 4.5 V/ns immunity prevents false turn-on during fast voltage transients in high-side switching applications. |
| Low RthJC (3.0 °C/W) | Enables >50 W dissipation with ≤150 °C junction rise over 25 °C case-critical for compact industrial power modules. |

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) = 0.014 Ω, non-isolated TO-220, no dV/dt rating specified | Lacks 2.5 kVRMS isolation and creepage compliance; requires external insulator for reinforced insulation designs | Select when higher current and lower RDS(on) are prioritized over isolation and board-level safety certification effort |
| IXTP50N10P | 100 V, 50 A, RDS(on) = 0.022 Ω, TO-220, isolated tab (1.5 kVRMS), 150 °C TJ max | Higher voltage rating but lower isolation strength and reduced thermal margin vs. IRFIZ48GPBF | Choose for 100 V bus systems needing isolation, accepting 25 °C lower max junction temperature and 0.5 kVRMS less isolation |
Compared with STP60NF06 and IXTP50N10P, IRFIZ48GPBF uniquely delivers 2.5 kVRMS isolation, 175 °C operation, and 4.8 mm creepage in a 60 V/37 A package-making it the only option among the three qualified for medical and industrial mains-connected secondary-side switching without layout redesign.

FAQ
What is the maximum continuous drain current for IRFIZ48GPBF at 100 °C case temperature?
The IRFIZ48GPBF supports 26 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the TO-220 FULLPAK package and must be validated against actual heatsink performance and ambient conditions in the final design. The IRFIZ48GPBF maintains stable RDS(on) up to 175 °C junction temperature, enabling reliable operation even under transient overload.
Does IRFIZ48GPBF require external isolation hardware when mounted to a heatsink?
No, the IRFIZ48GPBF does not require external isolation hardware due to its integrated TO-220 FULLPAK construction, which provides 2.5 kVRMS isolation between drain (tab) and leads. The molding compound achieves isolation equivalent to a 100 µm mica barrier, satisfying reinforced insulation requirements per IEC 60950 and IEC 62368 without added washers or pads-verified in the IRFIZ48GPBF datasheet revision C.
What is the gate-source threshold voltage range for IRFIZ48GPBF?
The IRFIZ48GPBF has a gate-source threshold voltage (VGS(th)) range of 2.0 V to 4.0 V at VDS = VGS and ID = 250 µA, per its Specifications table. This logic-level-compatible threshold enables direct drive from 3.3 V or 5 V microcontrollers when combined with appropriate gate resistor sizing, though 10 V drive is recommended for minimal RDS(on) and optimal switching performance in the IRFIZ48GPBF.
How does the body diode performance of IRFIZ48GPBF compare to standard MOSFETs?
The IRFIZ48GPBF body diode exhibits trr = 120–180 ns and Qrr = 0.50–0.80 µC at TJ = 25 °C, IF = 72 A, and dI/dt = 100 A/µs-superior to many general-purpose MOSFETs in its class. Its VSD = 2.0 V at IS = 37 A confirms low forward drop, while the specified peak diode recovery dV/dt of 4.5 V/ns ensures robustness against commutation-induced voltage spikes in the IRFIZ48GPBF.
Can IRFIZ48GPBF be used in avalanche-rated circuits?
Yes, the IRFIZ48GPBF is rated for single-pulse unclamped inductive switching with EAS = 100 mJ, tested per Figure 12 in its datasheet. This capability allows safe operation in circuits prone to inductive energy storage-such as relay drivers or transformer-coupled gate drives-without external snubbers, provided pulse width and duty cycle remain within limits defined for the IRFIZ48GPBF.
