Product details
Overview
SIHP21N60EF-BE3 from Vishay Siliconix is a 600 V, 21 A N-channel enhancement-mode power MOSFET in TO-220AB package with fast body diode, optimized for high-efficiency LLC and phase-shifted bridge topologies in telecom and solar inverters. It delivers RDS(on) = 0.176 Ω at VGS = 10 V, Qg = 84 nC, and avalanche-rated EAS = 367 mJ.
For engineers reviewing the SIHP21N60EF-BE3 datasheet, SIHP21N60EF-BE3 pinout, SIHP21N60EF-BE3 application, or SIHP21N60EF-BE3 equivalent, key selection criteria include its low Qrr (1.52 μC), fast trr (270 ns), reduced Ciss (2030 pF), and robust UIS capability - critical for ZVS switching and high-reliability industrial SMPS designs.
Technical Context
This EF-series MOSFET employs silicon technology with optimized charge distribution to minimize reverse recovery losses in hard- and soft-switched converters. Its gate charge profile (Qgd/Qg = 28.6%) supports precise timing control in resonant topologies, while the low Coss(tr) (299 pF) enables predictable turn-off behavior under high dV/dt conditions.
The integrated fast body diode exhibits IRRM = 11 A and dV/dt immunity up to 50 V/ns, enabling reliable freewheeling in bidirectional current paths without external Schottky supplementation. Thermal resistance RthJC = 0.55 °C/W ensures efficient heat transfer to heatsinks in high-power-density 1–3 kW systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 600 V - supports 400 V DC bus designs with 50% safety margin for transient overvoltage in PV inverters and telecom rectifiers |
| RDS(on) max | 0.176 Ω at VGS = 10 V - limits conduction loss to ≤3.9 W at 11 A continuous, enabling thermally constrained PCB layouts |
| Qg max | 84 nC - reduces gate drive power requirement and allows use of lower-current drivers in high-frequency (>100 kHz) LLC controllers |
| Qrr max | 1.52 μC - cuts body diode switching loss by >40% vs. standard MOSFETs, directly improving efficiency in phase-shifted full-bridge converters |
| EAS | 367 mJ - withstands unclamped inductive switching events in welder output stages and battery charger flyback snubbers |
| trr | 270 ns - enables clean zero-voltage switching transitions in 3-level NPC inverters operating up to 100 kHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 600 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP22N60M2 | RDS(on) = 0.19 Ω, Qg = 72 nC, no specified Qrr or trr data in datasheet | Lacks published body diode recovery specs; not recommended for ZVS topologies requiring low Qrr | Prefer SIHP21N60EF-BE3 where trr < 300 ns and Qrr < 2 μC are mandatory for efficiency targets |
| IXFH20N60X | RDS(on) = 0.22 Ω, Qg = 65 nC, Qrr = 1.8 μC, trr = 320 ns | Higher Qrr and slower trr increase switching loss in 100+ kHz LLC designs | SIHP21N60EF-BE3 offers 15% lower Qrr and 18% faster trr - measurable improvement in 2 kW telecom PSU efficiency maps |

FAQ
What is the maximum continuous drain current rating for SIHP21N60EF-BE3 at 100 °C case temperature?
The SIHP21N60EF-BE3 supports 14 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-220AB package and must be validated against actual board-level thermal resistance in the target application. The SIHP21N60EF-BE3 maintains RDS(on) stability across this range due to its positive VGS(th) temperature coefficient.
Does SIHP21N60EF-BE3 have a fully characterized fast body diode, and what are its key recovery parameters?
Yes, the SIHP21N60EF-BE3 features a fully characterized fast body diode with trr = 270 ns (max), Qrr = 1.52 μC (max), and IRRM = 11 A (max) at TJ = 25 °C. These values are measured under standardized conditions (IF = IS = 11 A, dI/dt = 100 A/μs, VR = 400 V) and are integral to its use in ZVS circuits. The SIHP21N60EF-BE3 datasheet provides full diode forward voltage (VSD = 1.2 V) and reverse recovery waveforms.
Is SIHP21N60EF-BE3 suitable for avalanche-prone applications like welding equipment or active clamp circuits?
Yes, the SIHP21N60EF-BE3 is explicitly rated for unclamped inductive switching with EAS = 367 mJ (single-pulse, TJ = 25 °C). This makes it suitable for welding output stages and active-clamp flyback converters where inductive energy must be safely absorbed. The SIHP21N60EF-BE3's ruggedness is further enhanced by low Qrr, reducing secondary breakdown risk during repetitive avalanche events.
What is the gate threshold voltage range for SIHP21N60EF-BE3, and how does it affect drive circuit design?
The SIHP21N60EF-BE3 has a gate-source threshold voltage VGS(th) ranging from 2.0 V to 4.0 V at TJ = 25 °C. This ensures reliable turn-on with standard 10 V gate drivers while avoiding unintended conduction from noise. The SIHP21N60EF-BE3 requires VGS ≥ 10 V to achieve its rated RDS(on); drive circuits must sustain ≥12 V to accommodate drop across gate resistors and PCB traces.
How does the "-BE3" suffix in SIHP21N60EF-BE3 impact compliance and reliability?
The "-BE3" suffix indicates an alternate manufacturing location within Vishay's qualified global network and confirms lead (Pb)-free and halogen-free construction per RoHS Directive 2011/65/EU. Reliability data-including HTOL, UHAST, and TC testing-is composite across all qualified sites and applies identically to SIHP21N60EF-BE3. No performance or qualification differences exist between -BE3 and -GE3 variants.
