Product details

Overview

IRL630 from Vishay Siliconix is a logic-level N-channel power MOSFET in TO-220AB package, rated for 200 V V_DS, 9.0 A continuous drain current at T_C = 25 °C, and 0.40 Ω R_DS(on) at V_GS = 5 V. It supports fast switching, repetitive avalanche operation, and ease of paralleling in DC-DC converters and motor control circuits.

For engineers reviewing the IRL630 datasheet, IRL630 pinout, IRL630 application, or IRL630 equivalent, key selection criteria include its logic-level gate drive (V_GS(th) = 1.0–2.0 V), low R_DS(on) at 4–5 V, avalanche energy rating (E_AS = 220 mJ), and TO-220AB thermal performance (R_thJC = 2.5 °C/W).

Technical Context

The IRL630 employs third-generation trench-gate silicon technology optimized for low conduction loss and robust unclamped inductive switching. Its dynamic dV/dt rating (5.0 V/ns) and body diode recovery time (t_rr = 220 ns typical) support reliable operation in hard-switched topologies.

Designed for logic-level drive compatibility, it delivers full enhancement at V_GS = 4.0 V (R_DS(on) ≤ 0.50 Ω) and maintains stable threshold voltage (V_GS(th) = 1.0–2.0 V) across -55 to +150 °C junction temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - supports input voltages up to 170 V DC in offline SMPS or 48 V industrial bus systems
R_DS(on) @ V_GS = 5 V	0.40 Ω - enables <1.8 W conduction loss at 6.7 A, reducing heatsink requirements
I_D (continuous, T_C = 25 °C)	9.0 A - sufficient for 75 W load switching with margin in TO-220AB package
Q_g (max)	24 nC - determines gate driver current demand (~1.2 A peak for 20 ns rise time)
E_AS	220 mJ - allows safe single-pulse inductive energy absorption without external snubber
t_rr	220 ns - limits reverse recovery losses in synchronous rectification and half-bridge configurations
V_GS(th)	1.0–2.0 V - ensures full turn-on with standard 3.3 V or 5 V microcontroller GPIO

Pinout & Package

IRL630 uses the industry-standard TO-220AB package with isolated tab (drain-connected), offering low thermal resistance (R_thJC = 2.5 °C/W) and mechanical compatibility with standard heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control terminal	Receives logic-level voltage (≥4 V) to fully enhance channel; requires <24 nC charge for full transition
D (Drain)	High-side power output	Internally connected to metal tab; must be electrically isolated from heatsink unless system ground reference permits
S (Source)	Power return / reference node	Serves as local ground for gate drive; source inductance (L_S = 7.5 nH) affects switching ringing in high-dI/dt applications

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4.0 V (R_DS(on) ≤ 0.50 Ω), eliminating need for gate boosters in 3.3/5 V control systems
Repetitive avalanche rated	Rated for I_AR = 9.0 A and E_AR = 10 mJ, enabling robustness against transient overloads without derating
Dynamic dV/dt immunity	Specified at 5.0 V/ns - suppresses false turn-on during high-speed voltage transients in bridge-leg configurations
Low Q_gd/Q_g ratio	Q_gd = 13.5 nC / Q_g = 24 nC ≈ 56% - improves Miller immunity and reduces switching instability in high-side applications
RoHS-compliant packaging	Available in Pb-free (IRL630PbF) and halogen-free (IRL630PbF-BE3) variants per Vishay specification 99912

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
STP20NM60FD	600 V V_DS, 0.32 Ω R_DS(on) @ 10 V, not logic-level (V_GS(th) = 3–5 V)	Requires gate driver for 3.3 V control; better for higher-voltage PFC stages	Select when >400 V blocking is needed and gate drive voltage ≥10 V is available
IRFZ44N	55 V V_DS, 0.028 Ω R_DS(on) @ 10 V, logic-level compatible but lower voltage rating	Not suitable for 200 V bus; optimized for 12–24 V motor drives	Choose only for low-voltage (<60 V) high-current applications where footprint and cost are critical

Compared with STP20NM60FD and IRFZ44N, the IRL630 uniquely balances 200 V rating, true logic-level operation, and TO-220AB thermal performance-making it optimal for 48 V industrial power stages where gate drive simplicity and avalanche ruggedness are mandatory.

FAQ

What is the maximum continuous drain current for IRL630 at 100 °C case temperature?

The IRL630 supports 5.7 A continuous drain current at T_C = 100 °C, derived from its linear derating factor of 0.40 W/°C and 50 W maximum power dissipation at 25 °C. This value is confirmed in Vishay's absolute maximum ratings table and reflects real thermal limits under sustained conduction in TO-220AB mounting conditions.

Does IRL630 have avalanche capability, and how is it specified?

Yes, the IRL630 is repetitively avalanche rated with I_AR = 9.0 A and E_AR = 10 mJ, and single-pulse rated for E_AS = 220 mJ. These values are measured under standardized unclamped inductive test conditions (V_DD = 100 V, L = 10 mH, T_J initial = 25 °C) per Vishay's datasheet Figure 12.

Is IRL630 compatible with 3.3 V microcontroller GPIO for direct gate drive?

Yes, the IRL630 is a true logic-level MOSFET with V_GS(th) = 1.0–2.0 V and guaranteed R_DS(on) ≤ 0.50 Ω at V_GS = 4.0 V. At 3.3 V, it remains partially enhanced (R_DS(on) ~0.65 Ω typ), making it usable with 3.3 V MCUs in moderate-current applications where slight conduction loss increase is acceptable.

What is the body diode forward voltage of IRL630, and how does it affect synchronous rectification?

The IRL630 body diode exhibits V_SD = 1.7 V at I_S = 9.0 A and T_J = 25 °C. In synchronous rectification, this forward drop contributes to conduction loss before gate turn-on; its 220 ns reverse recovery time (t_rr) must be managed via precise timing to avoid shoot-through in half-bridge topologies.

How does the thermal resistance of IRL630 impact heatsink selection?

With R_thJC = 2.5 °C/W and R_thJA = 62 °C/W (no heatsink), the IRL630 requires a heatsink when dissipating >2.5 W continuously. For example, at 9.0 A and 0.40 Ω R_DS(on), conduction loss is 32.4 W - demanding a heatsink with R_thSA ≤ 0.9 °C/W to maintain T_J < 150 °C at 25 °C ambient.
