Product details
Overview
IRFP354PBF from Infineon Technologies (formerly International Rectifier) is a 1000V, 4.8A N-channel enhancement-mode power MOSFET in TO-247AC package, featuring 2.5Ω RDS(on) at VGS = 10V and 25°C, 60nC total gate charge, and 100% avalanche-rated operation. It serves as a high-voltage switching element in offline SMPS, AC motor drives, and industrial DC-DC converters.
For engineers reviewing the IRFP354PBF datasheet, IRFP354PBF pinout, IRFP354PBF application, or IRFP354PBF equivalent, key selection criteria include its 1000V blocking voltage, 2.5Ω on-resistance, 60nC gate charge, avalanche ruggedness, and TO-247AC thermal performance for high-reliability 50/60Hz line-powered systems.
Technical Context
This MOSFET employs planar vertical DMOS technology with optimized cell layout to achieve stable 1000V VDSS and low RDS(on) while maintaining robust safe operating area (SOA) up to 10ms. Its gate threshold voltage of 2–4V enables direct drive from standard 5V logic controllers without level-shifting.
The device supports repetitive avalanche energy rating of 190mJ (TC = 25°C), enabling reliable operation under inductive switching transients in flyback and forward converters. Its 125°C maximum junction temperature and 0.83°C/W RθJC support conduction-limited thermal design in forced-air-cooled enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 1000V - Supports direct connection to 700VDC bus or 480VAC line after rectification without derating. |
| RDS(on) max | 2.5Ω @ VGS = 10V, TJ = 25°C - Enables <12W conduction loss at 2A continuous drain current. |
| Qg | 60nC - Determines gate driver power requirement; compatible with IR2110 or UCC3732x drivers. |
| EAS | 190mJ - Allows single-pulse inductive turn-off without external snubber in 1kW motor control inverters. |
| RθJC | 0.83°C/W - Enables 75°C temperature rise above case at 90W dissipation with minimal heatsink. |
| ID continuous | 4.8A @ TC = 25°C - Rated for sustained load current in industrial power supplies with adequate heatsinking. |
Pinout & Package
IRFP354PBF uses the industry-standard TO-247AC package with isolated tab (drain-connected), offering mechanical robustness and thermal interface compatibility with standard mounting hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main high-side current path | Electrically connected to metal tab; requires insulating washer when mounted to grounded heatsink. |
| Gate | Control terminal | Receives voltage-controlled signal; 2–4V VGS(th) allows TTL/CMOS-level drive with margin. |
| Source | Reference node for gate drive | Serves as return path for load current and gate drive loop; must be low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Avalanche Tested | Guarantees single-pulse ruggedness up to 190mJ, eliminating need for external clamping in cost-sensitive flyback designs. |
| Lead-Free (PbF) | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profile, enabling drop-in replacement in legacy leaded assembly lines. |
| Enhancement-Mode Operation | Ensures normally-off behavior-no external bias required-improving system safety during startup and fault conditions. |
| Low Gate Charge | 60nC Qg reduces switching losses and driver complexity in 20–100kHz SMPS applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STW12NK100Z | 1000V, 12A, 1.2Ω RDS(on), 110nC Qg, TO-247 package | Higher current rating but higher gate charge; better for lower-frequency, higher-current motor drives | Select STW12NK100Z when peak load current exceeds 6A and switching frequency remains below 50kHz. |
| IXTH12N100L | 1000V, 12A, 1.4Ω RDS(on), 85nC Qg, TO-247 package, logic-level gate | Logic-level VGS(th) (1–2.5V); requires no gate driver in microcontroller-driven systems | Choose IXTH12N100L when direct MCU GPIO drive is needed and gate driver ICs must be eliminated. |
Compared with STW12NK100Z and IXTH12N100L, the IRFP354PBF offers lower gate charge and tighter RDS(on) tolerance at 4.8A, making it optimal for medium-power, medium-frequency (50–100kHz) applications where driver efficiency and thermal margin are prioritized over peak current capability.

FAQ
What is the maximum junction temperature rating for IRFP354PBF?
The IRFP354PBF has a maximum junction temperature (TJ) of 125°C, validated per JEDEC JESD22-A108. This rating applies under continuous conduction mode with proper heatsinking and ensures stable RDS(on) and SOA performance across industrial ambient conditions. Derating is required above 25°C case temperature per the published thermal resistance curve in the IRFP354PBF datasheet.
Is IRFP354PBF RoHS-compliant and lead-free?
Yes, IRFP354PBF is RoHS-compliant and lead-free (PbF), as indicated by the "PbF" suffix and confirmed in Infineon's official material declaration. It meets JEDEC J-STD-020 moisture sensitivity level 1 and supports standard Pb-free reflow profiles up to 260°C peak temperature, enabling compatibility with modern SMT assembly lines.
Does IRFP354PBF require a gate driver IC?
IRFP354PBF can be driven directly by 5V logic-level controllers due to its 2–4V gate threshold voltage, but a dedicated gate driver IC (e.g., IR2110 or TC4420) is recommended for fast switching (>50kHz), low gate loop inductance, and robust noise immunity. The 60nC total gate charge makes driver selection critical for minimizing switching losses in high-frequency SMPS.
What is the safe operating area (SOA) limitation for IRFP354PBF at 100°C case temperature?
At TC = 100°C, the IRFP354PBF SOA is limited to 1.2A at 400V for 10ms pulse width, per the manufacturer's published SOA graph. This reflects reduced thermal headroom and must be verified against actual layout parasitics and heatsink performance. Continuous DC operation above 2.5A requires active cooling to maintain TJ ≤ 125°C.
Can IRFP354PBF replace IRFP450 in existing designs?
IRFP354PBF is not a direct replacement for IRFP450 due to differences in voltage rating (1000V vs. 500V) and RDS(on) (2.5Ω vs. 0.4Ω). While both share TO-247AC packaging, substituting IRFP354PBF into an IRFP450-based design may cause excessive conduction loss unless the circuit operates at significantly lower current. Re-evaluation of thermal and SOA margins is mandatory before substitution.
