Product details

Overview

IRL640PBF-BE3 from Vishay Siliconix is a logic-level N-channel power MOSFET in TO-220AB package, rated for 200 V V_DS, 17 A continuous drain current at T_C = 25 °C, and 0.18 Ω R_DS(on) at V_GS = 5 V. It supports fast switching, repetitive avalanche operation, and ease of paralleling in DC-DC converters, motor drives, and power supplies.

For engineers reviewing the IRL640PBF-BE3 datasheet, IRL640PBF-BE3 pinout, IRL640PBF-BE3 application, or IRL640PBF-BE3 equivalent, key selection criteria include its logic-level gate drive (V_GS(th) = 1.0–2.0 V), low R_DS(on) at 4 V/5 V, 66 nC total gate charge, and robust 580 mJ single-pulse avalanche energy rating.

Technical Context

This MOSFET employs third-generation silicon technology optimized for ruggedness and low conduction loss. Its dynamic dV/dt rating (5.0 V/ns) and specified body diode recovery (t_rr = 310–470 ns, Q_rr = 3.2–4.8 μC) support reliable operation in inductive switching circuits.

The device features integrated body diode with V_SD = 2.0 V at I_S = 17 A and is characterized for linear derating (1.0 W/°C) above 25 °C case temperature. Thermal resistance from junction-to-case is 1.0 °C/W, enabling high-power dissipation up to 125 W at T_C = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - supports input rails up to 160 V DC with margin for transients
R_DS(on) @ V_GS = 5 V	0.18 Ω - enables ≤3.1 W conduction loss at 13 A continuous load
Q_g	66 nC - determines gate driver current requirement (~1.3 A peak for 50 ns rise)
I_D continuous @ T_C = 25 °C	17 A - usable in medium-power SMPS and motor control stages
E_AS	580 mJ - withstands unclamped inductive energy without failure in flyback or solenoid drivers
t_r/t_f	83 ns / 52 ns - supports switching frequencies up to ~500 kHz with controlled EMI
V_GS(th)	1.0–2.0 V - fully enhanced by standard 3.3 V or 5 V microcontroller GPIO

Pinout & Package

IRL640PBF-BE3 uses the industry-standard TO-220AB package with isolated tab (drain-connected), offering low thermal resistance (R_thJC = 1.0 °C/W) and mechanical compatibility with common heatsinks using M3 screws.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output terminal	Electrically connected to metal tab; requires insulating washer when mounted to grounded heatsink
Gate	Control electrode	High-impedance input requiring <100 nA leakage; sensitive to ESD; driven directly by logic-level MCU outputs
Source	Reference node for gate drive and current return	Common connection point for load return and gate drive reference; defines local ground in high-side configurations

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) ≤ 2.0 V ensures full enhancement with 3.3 V or 5 V controllers without level-shifting
Repetitive avalanche rated	Rated for I_AR = 10 A and E_AR = 13 mJ - enables reliable operation under transient overloads in industrial controls
Dynamic dV/dt immunity	5.0 V/ns rating prevents false turn-on during high-speed voltage transients in half-bridge topologies
Low Q_gd/Q_g ratio	38/66 ≈ 58 % - improves Miller immunity and reduces switching instability in hard-switched converters
RoHS-compliant & halogen-free	IRL640PBF-BE3 meets JEDEC J-STD-609A Class 1 moisture sensitivity and IPC-1752 material declaration requirements

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
IRF640NPbF	V_GS(th) = 2.0–4.0 V; not logic-level; R_DS(on) = 0.18 Ω only at V_GS = 10 V	Requires 10 V gate drive; unsuitable for 3.3 V systems without buffer	Select IRL640PBF-BE3 when interfacing directly with low-voltage MCUs or FPGAs
STP20NM60FD	600 V V_DS; 0.30 Ω R_DS(on) @ 10 V; faster t_r (15 ns); no avalanche rating	Better for higher bus voltages but higher conduction loss at 200 V; no E_AS guarantee	Choose STP20NM60FD only if 600 V rating is mandatory and avalanche robustness is secondary

Compared with IRF640NPbF and STP20NM60FD, IRL640PBF-BE3 uniquely delivers logic-level operation with verified 580 mJ avalanche energy and 5.0 V/ns dV/dt immunity-critical for cost-sensitive, low-voltage industrial power stages where gate drive simplicity and transient robustness are prioritized over ultra-high voltage rating.

FAQ

What is the maximum continuous drain current for IRL640PBF-BE3 at 100 °C case temperature?

The IRL640PBF-BE3 supports 11 A continuous drain current at T_C = 100 °C, per its absolute maximum ratings table. This derating reflects thermal limitations of the TO-220AB package and must be validated with actual heatsink performance and ambient conditions. Designers should consult Fig. 9 (Maximum Drain Current vs. Case Temperature) in the Vishay datasheet S21-1046-Rev. D to confirm safe operating area boundaries for their specific layout.

Does IRL640PBF-BE3 have a guaranteed avalanche energy rating?

Yes, IRL640PBF-BE3 is repetitively avalanche rated with E_AR = 13 mJ and single-pulse E_AS = 580 mJ (tested per Fig. 12). These values are measured under defined conditions: V_DD = 50 V, L = 3.0 mH, R_g = 25 Ω, and starting T_J = 25 °C. The device's ruggedized construction enables reliable operation in inductive switching applications such as relay drivers and flyback converters where voltage transients occur.

Is IRL640PBF-BE3 compatible with 3.3 V microcontroller GPIOs?

Yes, IRL640PBF-BE3 is explicitly designed as a logic-level MOSFET with V_GS(th) = 1.0–2.0 V and R_DS(on) specified at V_GS = 4 V and 5 V. At 3.3 V, it achieves partial enhancement (typically R_DS(on) ≈ 0.27 Ω), sufficient for many medium-current applications. For full enhancement and minimal conduction loss, 5 V drive is recommended - easily achieved via buffered GPIO or dedicated gate driver.

What is the thermal resistance from junction to case for IRL640PBF-BE3?

The maximum junction-to-case (drain) thermal resistance R_thJC for IRL640PBF-BE3 is 1.0 °C/W, as stated in the Thermal Resistance Ratings table. This value assumes proper mounting with thermal grease on a flat heatsink surface. Actual thermal performance depends on interface quality, heatsink size, and airflow; designers should use this parameter with R_thCS = 0.50 °C/W and system-level R_thCA to calculate total junction-to-ambient path.

How does the body diode performance of IRL640PBF-BE3 compare to standard rectifiers?

The intrinsic body diode of IRL640PBF-BE3 has V_SD = 2.0 V at I_S = 17 A and t_rr = 310–470 ns, making it slower and higher-drop than Schottky diodes but suitable for synchronous rectification or freewheeling where active control is preferred. Its Q_rr = 3.2–4.8 μC contributes to switching loss during turn-off; for high-frequency designs, external diode clamping or synchronous drive may be needed to manage recovery effects.
