Product details
Overview
IRF620STRRPBF from Vishay Siliconix is a 200 V, 5.2 A N-channel enhancement-mode power MOSFET in D2PAK (TO-263) package, featuring 0.80 Ω RDS(on) at VGS = 10 V, 14 nC total gate charge, and repetitive avalanche rating-designed for high-efficiency DC-DC converters, motor control stages, and industrial power switching.
For engineers reviewing the IRF620STRRPBF datasheet, IRF620STRRPBF pinout, IRF620STRRPBF application, or IRF620STRRPBF equivalent, this part delivers verified surface-mount power switching with dynamic dv/dt immunity, fast 7.2 ns turn-on delay, and PCB-mount thermal dissipation up to 3.0 W-critical for compact, thermally constrained designs.
Technical Context
This third-generation power MOSFET uses planar V-groove silicon technology optimized for ruggedness and low conduction loss. Its 200 V VDS rating supports off-line and intermediate bus applications, while the 5.2 A continuous drain current at TC = 25 °C enables use in medium-power SMPS primary-side switches and half-bridge legs.
The device integrates a fast-recovery body diode (trr = 150–300 ns, Qrr = 0.91–1.8 μC) and exhibits stable RDS(on) temperature coefficient (+0.29 V/°C), enabling predictable thermal performance across -55 to +150 °C junction range without external current sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 200 V - Supports 170 V AC rectified input or 100 V DC bus with 2× safety margin. |
| RDS(on) @ VGS = 10 V | 0.80 Ω - Enables ≤2.0 W conduction loss at 5 A, suitable for <10 W output converters. |
| Qg | 14 nC - Low gate drive energy reduces controller loading and improves efficiency above 100 kHz. |
| ID (continuous) | 5.2 A @ TC = 25 °C - Requires ≥1"² FR-4 copper area for full-rated operation without heatsink. |
| EAS | 110 mJ - Withstands unclamped inductive switching events in relay drivers or solenoid controls. |
| tr/tf | 22 ns / 13 ns - Supports clean edge transitions in hard-switched topologies with minimal EMI. |
| RthJC | 2.5 °C/W - Enables direct thermal coupling to heatsink via exposed drain pad for >30 W pulsed operation. |
Pinout & Package
D2PAK (TO-263) surface-mount package with isolated gate, drain-connected thermal pad on underside, and 3-terminal layout optimized for high-current PCB routing and thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Accepts 10 V logic-level drive; 3.0 nC Qgs ensures fast turn-on with standard gate drivers. |
| D (Drain) | High-side power terminal | Internally connected to thermal pad; requires soldered copper pour for RthJC = 2.5 °C/W performance. |
| S (Source) | Reference node / return path | Low-inductance source loop critical-LS = 7.5 nH limits di/dt-induced shoot-through risk. |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | 5.0 mJ per pulse-enables robust operation in inductive load switching without snubbers. |
| Dynamic dv/dt immunity | 5.0 V/ns-prevents false turn-on during high-slew-rate transients in bridge configurations. |

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 |
|---|---|---|---|
| STP20NM50FP | 500 V VDS, 20 A ID, 0.23 Ω RDS(on), TO-220FP package | Higher voltage/current rating but larger footprint and higher Qg (45 nC); requires heatsink for same power level | Select when system requires >200 V isolation or >5 A continuous current with through-hole assembly. |
| IRFZ44NPBF | 55 V VDS, 49 A ID, 0.028 Ω RDS(on), TO-220 package | Lower voltage rating prevents use in 100+ V bus applications; superior RDS(on) only beneficial below 60 V | Select only for low-voltage (<60 V), high-current motor drives where IRF620STRRPBF's 200 V rating is excessive. |
Compared with STP20NM50FP and IRFZ44NPBF, IRF620STRRPBF offers optimal balance of voltage headroom, surface-mount compatibility, and thermal performance in 10–25 W industrial power stages-without requiring layout changes or additional thermal mass.

FAQ
What is the maximum continuous drain current for IRF620STRRPBF at 100 °C case temperature?
The IRF620STRRPBF supports 3.3 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package under sustained high-temperature operation-designers must ensure adequate PCB copper area or heatsinking to maintain safe junction temperatures below 150 °C. The IRF620STRRPBF's linear derating factor is 0.40 W/°C above 25 °C case temperature.
Does IRF620STRRPBF have a built-in body diode, and what are its key parameters?
Yes, the IRF620STRRPBF integrates a monolithic body diode with 5.2 A continuous forward current rating (IS) and 18 A pulsed capability (ISM). Key parameters include VSD = 1.8 V at IS = 5.2 A and TJ = 25 °C, reverse recovery time trr = 150–300 ns, and Qrr = 0.91–1.8 μC. These values are measured under standardized conditions (TJ = 25 °C, IF = 4.8 A, di/dt = 100 A/μs) and directly impact freewheeling efficiency in synchronous rectifiers and H-bridges.
Is IRF620STRRPBF RoHS-compliant and halogen-free?
Yes, IRF620STRRPBF is both RoHS-compliant and halogen-free, as confirmed in Vishay's official documentation (Document Number: 91028, Rev. E). It carries the "-GE3" suffix designation indicating lead (Pb)-free and halogen-free construction, meeting IPC-1752A material compliance requirements. No exemptions apply-the device contains no intentionally added brominated flame retardants or chlorine-based compounds.
What is the thermal resistance from junction to case (RthJC) for IRF620STRRPBF?
The IRF620STRRPBF has a maximum junction-to-case (drain) thermal resistance RthJC of 2.5 °C/W, measured from the silicon die to the exposed drain pad. This value assumes proper soldering of the thermal pad to ≥1"² of 2-oz copper on FR-4 PCB. Effective thermal design using this RthJC enables the IRF620STRRPBF to dissipate up to 50 W in heatsink-mounted configurations-critical for high-duty-cycle industrial switching applications.
Can IRF620STRRPBF be used in avalanche mode, and what are its rated energy limits?
Yes, IRF620STRRPBF is explicitly rated for repetitive avalanche operation with 5.0 mJ per pulse (EAR) and single-pulse avalanche energy of 110 mJ (EAS). These ratings are validated per test condition: VDD = 50 V, starting TJ = 25 °C, L = 6.1 mH, Rg = 25 Ω, IAS = 5.2 A. Use within these limits avoids permanent degradation-making the IRF620STRRPBF suitable for inductive load switching without external clamping components.
