Product details
Overview
IRF830STRL from Vishay Siliconix is a 500 V, 4.5 A N-channel power MOSFET in D2PAK (TO-263) surface-mount package, featuring 1.5 Ω RDS(on) at VGS = 10 V, 38 nC total gate charge, and repetitive avalanche rating-designed for high-voltage switching in offline SMPS, AC-DC adapters, and motor control circuits.
For engineers reviewing the IRF830STRL datasheet, IRF830STRL pinout, IRF830STRL application, or IRF830STRL equivalent, key selection criteria include its 500 V VDS, 74 W TC power dissipation, dV/dt ruggedness (3.5 V/ns), body diode recovery time (320–640 ns), and PCB-mount thermal resistance (40 °C/W).
Technical Context
This third-generation power MOSFET uses planar VDMOS technology optimized for fast switching and rugged unclamped inductive switching. Its dynamic dV/dt rating and 280 mJ single-pulse avalanche energy support reliable operation in hard-switched flyback and forward converters.
The device integrates a low-Qgd/Qg ratio (22/38 nC) and low internal source/drain inductance (LS = 7.5 nH, LD = 4.5 nH), enabling clean turn-off and reduced voltage overshoot in high-frequency topologies up to 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 500 V - supports primary-side switching in universal-input (85–265 VAC) offline power supplies |
| RDS(on) | 1.5 Ω @ VGS = 10 V - limits conduction loss to ≤15.2 W at 4.5 A DC, enabling compact heatsink design |
| Qg | 38 nC - determines gate drive power requirement (~3.8 mW at 100 kHz, VGS swing = 10 V) |
| EAS | 280 mJ - enables robust unclamped inductive switching without external snubbers in relay drivers or solenoid controls |
| TJ Range | −55 °C to +150 °C - ensures stable operation in industrial ambient environments with minimal derating |
| RthJC | 1.7 °C/W - allows direct thermal coupling to heatsink via exposed drain pad, critical for >5 W continuous dissipation |
| dV/dt Rating | 3.5 V/ns - suppresses false turn-on during high dv/dt transients in half-bridge configurations |
Pinout & Package
D2PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection; 3-pin configuration (G, D, S) compatible with standard PCB land patterns per Vishay AN826.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control terminal | Receives 10 V logic-level drive; 0.5–2.7 Ω gate input resistance minimizes RC delay with standard drivers |
| D (Drain) | High-voltage output node | Exposed copper pad serves as primary thermal path and high-current return; rated for 500 V blocking |
| S (Source) | Reference node / current return | Low-inductance connection (LS = 7.5 nH) reduces switching noise and improves di/dt immunity |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | 7.4 mJ per pulse - enables reliable operation under transient overloads without SOA derating |
| Dynamic dV/dt rating | 3.5 V/ns - prevents spurious turn-on in high-noise industrial environments |
| Fast switching | td(on) = 8.2 ns, tr = 16 ns - supports >100 kHz operation with minimal dead-time penalty |
| Low Qgd/Qg ratio | 57.9% - reduces Miller-induced voltage spikes and improves gate drive efficiency |
| RoHS-compliant Pb-free | IRF830STRLPbF variant - meets EU Directive 2011/65/EU without exemption |
Applications
| Offline AC-DC Adapters | Industrial Motor Drives |
|---|---|
|

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 |
|---|---|---|---|
| STP5NK50ZFP | 500 V, 4.5 A, RDS(on) = 1.4 Ω, Qg = 32 nC, TO-220FP package | Through-hole mounting; higher RthJA (62 °C/W vs. 40 °C/W PCB mount) | Prefer when board space allows through-hole assembly and thermal interface to heatsink is mechanically constrained. |
| IXTP50N10P | 100 V, 50 A, RDS(on) = 0.022 Ω, TO-220 package - not voltage-compatible | Lower VDS rating invalidates use in 400 V+ bus applications | Not suitable as direct alternative; only applicable in low-voltage (<120 V) motor drives where IRF830STRL's voltage headroom is unnecessary. |
Compared with STP5NK50ZFP, IRF830STRL offers superior thermal performance on PCB (40 vs. 62 °C/W) and tape-and-reel packaging for automated assembly, while IXTP50N10P lacks the 500 V rating required for mains-referenced designs-making IRF830STRL the only viable option for universal-input offline power stages.

FAQ
What is the maximum continuous drain current for IRF830STRL at 100 °C case temperature?
The IRF830STRL supports 2.9 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 sustained high-temperature operation and must be validated against actual PCB layout and heatsinking in the target application.
Does IRF830STRL require a gate resistor for safe operation?
Yes, IRF830STRL requires an external gate resistor to control switching speed and suppress ringing. The datasheet recommends Rg = 25 Ω for avalanche testing and typical designs use 10–47 Ω to balance EMI, switching loss, and voltage overshoot-especially critical given its 3.5 V/ns dV/dt rating and 22 nC Qgd.
Is IRF830STRL RoHS-compliant and halogen-free?
The IRF830STRLPbF variant is lead-free and halogen-free per Vishay's material categorization (document 99912). It complies with EU Directive 2011/65/EU and carries the "-GE3" suffix in halogen-free versions (e.g., SiHF830STRL-GE3), confirming full regulatory alignment for export and industrial deployment.
Can IRF830STRL replace IRF830 in existing designs?
IRF830STRL is the surface-mount D2PAK version of the through-hole IRF830 (TO-220). While electrically identical in VDS, RDS(on), and Qg, the package change requires PCB redesign: D2PAK demands larger thermal pads (per AN826), different reflow profile, and altered mechanical mounting-no drop-in replacement without layout revision.
What is the body diode reverse recovery charge (Qrr) of IRF830STRL?
The IRF830STRL exhibits Qrr = 1.0–2.0 μC at TJ = 25 °C, IF = 3.1 A, and dI/dt = 100 A/μs. This value directly impacts switching loss in synchronous rectification and freewheeling paths; designers should account for it in loss budgets and consider snubber optimization when operating above 50 kHz.
