Product details
Overview
IRFR430ATRRPBF from Vishay Siliconix is a 500 V, 5.0 A N-channel enhancement-mode power MOSFET in DPAK (TO-252) package, featuring RDS(on) = 1.7 Ω at VGS = 10 V, Qg = 24 nC, and avalanche-rated operation for robust high-voltage switching in offline SMPS and UPS systems.
For engineers reviewing the IRFR430ATRRPBF datasheet, IRFR430ATRRPBF pinout, IRFR430ATRRPBF application, or IRFR430ATRRPBF equivalent, key selection criteria include its 500 V VDS, 1.7 Ω on-resistance at 10 V gate drive, 24 nC total gate charge, and DPAK thermal performance with RthJC = 1.1 °C/W - critical for high-reliability power conversion designs.
Technical Context
This device uses planar vertical DMOS technology optimized for high-voltage unclamped inductive switching, with fully characterized Ciss (490 pF), Coss (75 pF), and Crss (4.5 pF) enabling accurate snubber and gate-drive design. Its 130 mJ single-pulse avalanche energy rating supports reliable operation under transient overloads.
The gate threshold voltage range (2.0–4.5 V) and low gate leakage (±100 nA) ensure stable turn-on control across temperature, while the body diode's trr = 410–620 ns and Qrr = 1.4–2.1 μC are specified for hard-switched freewheeling applications without external diode supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 500 V - supports primary-side switching in universal-input AC/DC converters up to 400 V DC bus |
| RDS(on) | 1.7 Ω @ VGS = 10 V - enables <5 W conduction loss at 5 A continuous drain current |
| Qg | 24 nC - determines gate driver current requirement (~1.6 mA avg. for 100 kHz, 10 V swing) |
| EAS | 130 mJ - allows safe operation during 5 A inductive turn-off transients without external clamping |
| tr/tf | 27 ns / 16 ns - supports >500 kHz switching in resonant and hard-switched topologies |
| TJ Range | −55 °C to +150 °C - qualified for industrial and telecom power supply environments |
| RthJC | 1.1 °C/W - enables 110 W power dissipation with ≤121 °C junction rise above 25 °C case |
Pinout & Package
DPAK (TO-252) package with exposed drain pad for thermal conduction to PCB copper; standard 3-pin surface-mount outline measuring 6.22 mm × 6.73 mm × 1.78 mm (L × W × H), compatible with IPC-7351B SO-252 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Accepts 10 V logic-level drive; 6.5 nC Qgs ensures fast turn-on with minimal Miller effect |
| D (Drain) | High-voltage power terminal | Connected to exposed backside thermal pad; carries full load current and withstands 500 V blocking |
| S (Source) | Reference and return path | Common node for gate drive return and current sensing; low-inductance layout critical for dV/dt immunity |
Key Features
| Feature | Design Value |
|---|---|
| Low Qg (24 nC) | Reduces gate driver power loss and simplifies drive circuitry for high-frequency SMPS |
| Specified Coss eff. (51 pF) | Enables precise calculation of turn-off energy loss and snubber sizing in flyback and LLC converters |
| Avalanche-rated (EAS = 130 mJ) | Eliminates need for external RCD clamp in cost-sensitive offline adapters and UPS inverters |
| Body diode trr (410–620 ns) | Supports synchronous rectification replacement in medium-frequency forward converters |
| 100 % UIS tested | Guarantees ruggedness against unclamped inductive switching stress in real-world board-level conditions |
Applications
| AC/DC Adapter Primary Switch | UPS Inverter Half-Bridge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel high-voltage power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP5NK50ZFP | 500 V, 4.5 A, RDS(on) = 1.4 Ω, Qg = 22 nC, TO-220FP package | Higher current rating but through-hole mounting; lacks DPAK thermal pad integration | Prefer when higher peak current margin is needed and PCB space allows through-hole assembly |
| IXTP50N10P | 100 V, 50 A, RDS(on) = 0.022 Ω, TO-220 package - not voltage-compatible | Lower VDS makes it unsuitable for 400 V bus applications; only viable in low-voltage DC/DC | Exclude for any 500 V or offline AC/DC use; consider only for 12–48 V secondary-side switching |
Compared with STP5NK50ZFP, IRFR430ATRRPBF offers superior thermal interface via DPAK drain pad and lower profile for compact layouts, while IXTP50N10P is not a functional substitute due to its 100 V rating - engineers must verify VDS headroom before substitution.

FAQ
What is the maximum continuous drain current for IRFR430ATRRPBF at 100 °C case temperature?
The maximum continuous drain current for IRFR430ATRRPBF is 3.2 A at TC = 100 °C, derated linearly from 5.0 A at 25 °C using a factor of 0.91 W/°C. This value reflects thermal limitation of the DPAK package, not silicon capability, and assumes proper PCB copper area per Vishay Application Note 826.
Does IRFR430ATRRPBF have a fully characterized body diode for synchronous rectification?
Yes, IRFR430ATRRPBF specifies body diode parameters including VSD = 1.5 V at IS = 5.0 A, trr = 410–620 ns, and Qrr = 1.4–2.1 μC at TJ = 25 °C. These values are measured under controlled dI/dt and temperature conditions and support design of self-driven synchronous rectifiers in forward and LLC converters.
Is IRFR430ATRRPBF RoHS-compliant and halogen-free?
Yes, IRFR430ATRRPBF is lead (Pb)-free and halogen-free, conforming to Vishay's material categorization per document 99912. The "TRRPBF" suffix explicitly denotes Pb-free and halogen-free construction, verified per JEDEC J-STD-609 and IEC 61249-2-21 standards.
What is the gate-source threshold voltage range for IRFR430ATRRPBF?
The gate-source threshold voltage (VGS(th)) for IRFR430ATRRPBF is specified from 2.0 V to 4.5 V at ID = 250 μA and TJ = 25 °C. This range ensures reliable turn-on with standard 5 V or 10 V gate drivers while maintaining noise immunity in noisy power environments.
Can IRFR430ATRRPBF be used in avalanche mode repeatedly?
IRFR430ATRRPBF is rated for repetitive avalanche with IAR = 5.0 A and EAR = 11 mJ per pulse, but operation must comply with pulse width and duty cycle limits defined in Figure 11 of the datasheet. Repetitive avalanche is not recommended for continuous operation - it is a survival rating for fault conditions only.
