Product details

Overview

IRFI630G from Vishay Siliconix is a 200 V, 5.9 A N-channel power MOSFET in TO-220 FULLPAK package with isolated tab, 0.40 Ω R_DS(on) at V_GS = 10 V, 43 nC total gate charge, and 2.5 kV_RMS isolation - used in offline SMPS primary-side switching and industrial motor control.

For engineers reviewing the IRFI630G datasheet, IRFI630G pinout, IRFI630G application, or IRFI630G equivalent, this page delivers verified electrical specs, thermal performance, avalanche capability, isolation rating, and real-world design context for high-voltage DC-DC and AC-DC converter implementations.

Technical Context

This third-generation power MOSFET uses planar V-groove technology to achieve rugged unclamped inductive switching (230 mJ single-pulse E_AS) and stable dynamic dV/dt immunity (5.0 V/ns). Its isolated TO-220 FULLPAK package integrates a thermally efficient molding compound enabling direct heatsink mounting without mica washers.

The device features low gate charge (Q_g = 43 nC) and fast switching (t_d(on) = 9.4 ns, t_f = 20 ns), optimized for hard-switched flyback and forward converters operating up to 100 kHz. Body diode recovery (t_rr = 170–340 ns, Q_rr = 1.1–2.2 μC) supports moderate-frequency synchronous rectification where external diode replacement is considered.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - supports 170 VAC mains input with 2× safety margin in offline converters
R_DS(on)	0.40 Ω @ V_GS = 10 V - limits conduction loss to ≤ 1.4 W at 5.9 A continuous drain current
Q_g	43 nC - determines gate driver power requirement (~1.3 mW at 100 kHz, V_GS swing = 10 V)
E_AS	230 mJ - enables reliable operation under unclamped inductive load transients without snubber
R_thJC	3.6 °C/W - allows 35 W dissipation with ≤ 126 °C junction rise above 25 °C case temperature
Isolation	2.5 kV_RMS, 60 s - eliminates need for insulating hardware in Class I AC-connected equipment
t_rr	170–340 ns - defines minimum dead time required to prevent shoot-through in half-bridge topologies

Pinout & Package

IRFI630G uses the TO-220 FULLPAK package: isolated metal tab (drain), 3-pin through-hole outline (12.9–13.3 mm length, 10.0–10.3 mm width, 4.6–4.8 mm thickness), with creepage distance ≥ 4.8 mm between sink and leads.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control terminal	Accepts 10 V logic-level drive; threshold voltage 2.0–4.0 V ensures turn-on stability across temperature
D (Drain)	High-side power node	Connected to isolated tab; rated for 200 V blocking and 24 A pulsed current
S (Source)	Power return / reference	Common node for gate drive return and current sensing; body diode anode

Key Features

Feature	Design Value
Isolated TO-220 FULLPAK	Eliminates mica insulator and shoulder washer - reduces thermal resistance by ~25% vs. standard TO-220
2.5 kV_RMS isolation	Meets reinforced insulation requirements per IEC 60950-1 and IEC 62368-1 for primary-side power switches
Low R_thJC = 3.6 °C/W	Enables 35 W continuous dissipation with passive heatsinking in compact industrial enclosures
Dynamic dV/dt rating = 5.0 V/ns	Prevents false turn-on during high-slew-rate switching transitions in high-noise environments
Unclamped avalanche energy = 230 mJ	Supports robust operation in transformer leakage inductance clamp circuits without external TVS

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 V_DS, 0.23 Ω R_DS(on), TO-220FP (non-isolated), no certified isolation rating	Higher voltage headroom but requires external insulator; unsuitable for reinforced insulation designs	Select when higher blocking voltage is needed and isolation hardware can be added
FQP20N06L	60 V V_DS, 0.06 Ω R_DS(on), logic-level gate (V_GS(th) = 1–2.5 V), TO-220 (non-isolated)	Lower voltage rating; optimized for 12–24 V systems; not suitable for AC-line applications	Select only for low-voltage DC-DC where isolation and 200 V rating are unnecessary

Compared with STP20NM50FP and FQP20N06L, the IRFI630G uniquely combines 200 V rating, certified 2.5 kV_RMS isolation, and rugged avalanche performance - making it irreplaceable in safety-critical AC-input power stages where board-level insulation must be minimized.

FAQ

What is the maximum continuous drain current for IRFI630G at 100 °C case temperature?

The IRFI630G supports 3.7 A continuous drain current at T_C = 100 °C, derated linearly from 5.9 A at 25 °C using a 0.28 W/°C factor. This value reflects thermal limits of the TO-220 FULLPAK package and must be validated against actual heatsink performance and ambient conditions in the final layout. The IRFI630G datasheet specifies this limit in Absolute Maximum Ratings Table.

Does IRFI630G require a gate resistor for safe operation?

Yes, IRFI630G requires an external gate resistor to control switching speed and suppress oscillation. A typical value is 12–25 Ω, as used in the datasheet's switching time test circuit (Fig. 10a). This resistor damps gate loop inductance and limits peak gate current; omitting it risks overshoot, ringing, or false turn-on due to the device's 43 nC gate charge and low gate input resistance (0.6–3.3 Ω).

Can IRFI630G be used as a direct replacement for IRF630 in existing designs?

No - IRFI630G is not a drop-in replacement for IRF630. While both share V_DS = 200 V and similar R_DS(on), the IRFI630G uses an isolated TO-220 FULLPAK package (drain-connected tab), whereas IRF630 uses standard non-isolated TO-220. Substituting IRFI630G requires mechanical redesign to accommodate isolation and revised heatsink mounting - no PCB changes are sufficient.

What is the body diode forward voltage of IRFI630G at 5.9 A and 25 °C?

The body diode forward voltage (V_SD) of IRFI630G is 2.0 V maximum at I_S = 5.9 A, T_J = 25 °C, and V_GS = 0 V. This parameter is specified in the "Drain-Source Body Diode Characteristics" table and impacts conduction loss during freewheeling intervals in bridge configurations. The IRFI630G body diode exhibits soft recovery behavior, with Q_rr = 1.1–2.2 μC.

Is IRFI630G lead (Pb)-free and RoHS compliant?

Yes, IRFI630G is lead-free and RoHS compliant, as confirmed by its ordering variant IRFI630GPbF and Vishay's material categorization documentation (www.vishay.com/doc?99912). The device meets JEDEC J-STD-609A Class 2a marking requirements and is compatible with standard Pb-free reflow profiles up to 300 °C peak for 10 seconds, per the soldering recommendations in the datasheet.
