Product details
Overview
SIHF540STRL-GE3 from Vishay Siliconix is a 100 V, 28 A N-channel surface-mount power MOSFET in D2PAK (TO-263) package, featuring 0.077 Ω RDS(on) at VGS = 10 V, 72 nC total gate charge, and 175 °C maximum junction temperature - designed for high-current DC-DC converters, motor drives, and industrial power switching.
For engineers reviewing the SIHF540STRL-GE3 datasheet, SIHF540STRL-GE3 pinout, SIHF540STRL-GE3 application, or SIHF540STRL-GE3 equivalent, key selection criteria include avalanche ruggedness (230 mJ single-pulse EAS), fast switching (11 ns td(on), 44 ns tr), PCB-mount thermal performance (RthJA = 40 °C/W), and RoHS-compliant lead-free/halogen-free construction.
Technical Context
This third-generation power MOSFET uses planar V-groove silicon technology to achieve low on-resistance while maintaining robust unclamped inductive switching capability. Its dynamic dv/dt rating of 5.5 V/ns and repetitive avalanche rating support reliable operation in hard-switched topologies without external snubbers.
The device integrates a fast-recovery body diode (trr = 180–360 ns, Qrr = 1.3–2.8 μC) and exhibits low internal inductance (LD = 4.5 nH, LS = 7.5 nH), enabling stable paralleling and reduced ringing in high-frequency power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports 48 V and 96 V bus systems with margin for transients |
| RDS(on) @ VGS = 10 V | 0.077 Ω - enables ≤2.2 W conduction loss at 17 A continuous drain current |
| Qg | 72 nC - determines gate drive power requirement and switching speed trade-off |
| EAS | 230 mJ - allows safe operation under unclamped inductive load conditions without external protection |
| TJ(max) | +175 °C - permits high ambient operation in enclosed industrial enclosures |
| ID @ TC = 100 °C | 20 A - defines usable current derating for thermally constrained PCB-mount designs |
| PD (PCB mount) | 3.7 W - sets practical power limit when mounted on 1" FR-4 PCB without heatsink |
Pinout & Package
D2PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection; 3-terminal configuration (G, D, S); standard JEDEC outline per document 73397.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control terminal | Receives 10 V logic-level drive; requires <3.6 Ω gate resistance to avoid oscillation during fast switching |
| D (Drain) | High-side power output | Connected to exposed copper pad - must be routed to large thermal plane for heat dissipation |
| S (Source) | Reference/return path | Common node for gate drive return and current sensing; low-inductance layout critical for diode recovery stability |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Enables reliable operation in inductive load switching without external clamping circuits |
| Dynamic dv/dt rating | 5.5 V/ns - suppresses false turn-on during high-slew-rate voltage transients |
| Fast switching | 11 ns turn-on delay + 44 ns rise time - reduces switching losses in 100–500 kHz SMPS designs |
| Low RDS(on) × Qg figure-of-merit | 5.5 nC·Ω - balances conduction and switching loss for high-efficiency mid-power converters |
| RoHS-compliant, halogen-free | Meets IPC-1752A material declaration requirements for industrial and automotive supply chains |

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 |
|---|---|---|---|
| IRF540NPbF | Same die, but TO-220 package; higher RthJC (1.5 °C/W vs. 1.0 °C/W); no surface-mount compatibility | Requires through-hole PCB layout and mechanical heatsinking; unsuitable for dense SMT assemblies | Select only when board space allows vertical heatsink mounting and reflow soldering is not required. |
| STP10NK50ZFP | Zener-protected superjunction MOSFET; 500 V VDS, 0.58 Ω RDS(on); higher voltage rating but 7.5× higher on-resistance | Better suited for universal-input offline SMPS (>300 V DC link); not optimal for 48–100 V bus systems | Choose only if system requires >400 V blocking capability and can tolerate higher conduction loss. |
Compared with IRF540NPbF and STP10NK50ZFP, SIHF540STRL-GE3 delivers superior thermal performance in SMT layouts, lower conduction loss in mid-voltage industrial power stages, and optimized gate charge for efficient 100–300 kHz switching - making it the preferred choice for space-constrained, high-reliability 100 V applications.

FAQ
What is the maximum continuous drain current for SIHF540STRL-GE3 at 100 °C case temperature?
The SIHF540STRL-GE3 supports 20 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package under typical PCB-mount conditions and ensures long-term reliability without exceeding the 175 °C maximum junction temperature. The SIHF540STRL-GE3 maintains this rating across its full operating temperature range.
Does SIHF540STRL-GE3 have avalanche capability, and how is it rated?
Yes, the SIHF540STRL-GE3 is repetitively avalanche rated with 15 mJ EAR and single-pulse avalanche energy of 230 mJ (EAS). These values are measured under standardized conditions (VDD = 25 V, IAS = 28 A, TJ starting at 25 °C). The SIHF540STRL-GE3 leverages this ruggedness to withstand inductive switching stresses in motor drives and DC-DC converters without external protection components.
What is the gate threshold voltage range for SIHF540STRL-GE3, and is it compatible with 5 V logic?
The SIHF540STRL-GE3 has a gate threshold voltage (VGS(th)) range of 2.0 V to 4.0 V at TJ = 25 °C, confirming it is a standard-level MOSFET - not a logic-level device. It requires ≥10 V gate drive for full enhancement and minimal RDS(on). Driving the SIHF540STRL-GE3 with only 5 V will result in significantly elevated on-resistance and excessive conduction loss; a dedicated gate driver or level-shifter is necessary for microcontroller-based control.
How does the body diode performance of SIHF540STRL-GE3 impact its use in synchronous rectification?
The SIHF540STRL-GE3 features a body diode with trr = 180–360 ns and Qrr = 1.3–2.8 μC, which is relatively slow compared to dedicated Schottky or GaN devices. While usable in non-synchronous or freewheeling roles, the SIHF540STRL-GE3 is not recommended for high-frequency synchronous rectification where low Qrr is critical. Its body diode is best applied in low-duty-cycle, medium-frequency freewheeling paths - consistent with its design intent in the SIHF540STRL-GE3 datasheet.
What thermal resistance values apply to SIHF540STRL-GE3 in a standard PCB-mount configuration?
In a standard 1" square FR-4 PCB mount, the SIHF540STRL-GE3 exhibits RthJA = 40 °C/W and RthJC = 1.0 °C/W. These values assume proper copper pour under the exposed drain pad and define realistic thermal limits for layout design. The SIHF540STRL-GE3 achieves this performance via its D2PAK package's low-resistance thermal path from junction to case, enabling 3.7 W power dissipation without external heatsink - a key advantage over TO-220 alternatives.
