Product details

Overview

IRFBC40ASTRLPBF from Vishay Siliconix is a 600 V, 6.2 A N-channel power MOSFET in D2PAK (TO-263) package, featuring 1.2 Ω R_DS(on) at V_GS = 10 V, 42 nC total gate charge, and 570 mJ single-pulse avalanche energy-designed for high-voltage switching in offline SMPS topologies.

For engineers reviewing the IRFBC40ASTRLPBF datasheet, IRFBC40ASTRLPBF pinout, IRFBC40ASTRLPBF application, or IRFBC40ASTRLPBF equivalent, this device is evaluated for rugged unclamped inductive switching, fast diode recovery (t_rr = 431–647 ns), and stable operation up to 150 °C junction temperature in high-reliability industrial power converters.

Technical Context

This MOSFET employs planar vertical DMOS technology optimized for high-voltage hard-switching applications. Its low Q_gd/Q_gs ratio (2.0) and characterized C_{oss eff.} = 48 pF support controlled dV/dt and reduced switching loss during turn-off in forward and flyback converters.

The integral body diode is fully specified for reverse recovery (Q_rr = 1.8–2.8 μC, t_rr = 431–647 ns) and rated for repetitive avalanche (I_AR = 6.2 A, E_AR = 13 mJ), enabling robust operation in circuits with inductive loads and freewheeling paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports 400 V AC input rectified systems with ≥50 % voltage margin
R_DS(on)	1.2 Ω @ V_GS = 10 V - enables ≤46 W conduction loss at 6.2 A continuous drain current
Q_g	42 nC - determines gate drive power requirement and switching speed in 100–500 kHz SMPS
E_AS	570 mJ - specifies maximum single-pulse inductive energy handling without failure
t_rr	431–647 ns - defines diode recovery window affecting cross-conduction risk in bridge topologies

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP6NK60ZFP	600 V, 5.5 A, R_DS(on) = 1.2 Ω, Q_g = 32 nC, TO-220FP package	Lower peak current rating and different thermal profile; no D2PAK footprint compatibility	Preferred where lower gate drive power is critical and through-hole mounting is acceptable
IXTH6N60P	600 V, 6.0 A, R_DS(on) = 1.4 Ω, Q_g = 38 nC, TO-247 package	Higher R_DS(on), larger package, higher R_thJC (0.83 °C/W); not drop-in compatible	Selected when higher avalanche ruggedness (E_AS = 1000 mJ) outweighs footprint and thermal constraints

Compared with STP6NK60ZFP and IXTH6N60P, the IRFBC40ASTRLPBF offers optimal balance of D2PAK thermal performance (R_thJC = 1.0 °C/W), industry-standard 42 nC gate charge, and validated 570 mJ avalanche capability-making it especially suitable for space-constrained, high-reliability SMPS designs requiring surface-mount assembly.

FAQ

What is the maximum continuous drain current for IRFBC40ASTRLPBF at 100 °C case temperature?

The IRFBC40ASTRLPBF supports 3.9 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package and ensures safe operation within its 1.0 °C/W junction-to-case thermal resistance. Designers must verify heatsinking to maintain T_C ≤ 100 °C under full-load conditions to sustain this current rating in the IRFBC40ASTRLPBF.

Does IRFBC40ASTRLPBF have a fully characterized body diode for synchronous rectification?

Yes, the IRFBC40ASTRLPBF includes full characterization of its intrinsic body diode, including reverse recovery time (t_rr = 431–647 ns), reverse recovery charge (Q_rr = 1.8–2.8 μC), and forward voltage (V_SD = 1.5 V at I_S = 6.2 A). These parameters are measured and guaranteed per the datasheet, enabling accurate loss modeling in freewheeling and synchronous rectifier applications using the IRFBC40ASTRLPBF.

Is IRFBC40ASTRLPBF RoHS-compliant and halogen-free?

Yes, IRFBC40ASTRLPBF is RoHS-compliant and halogen-free, as confirmed by Vishay's material categorization documentation (www.vishay.com/doc?99912). The "PbF" suffix denotes lead-free termination, and the device meets JEDEC J-STD-609A Class 1 requirements. No exemptions apply, and the full compliance status is documented in the official IRFBC40AS datasheet revision E (S21-0943-Rev. E).

What is the gate-source threshold voltage range for IRFBC40ASTRLPBF?

The gate-source threshold voltage (V_GS(th)) for IRFBC40ASTRLPBF is specified as 2.0 V minimum to 4.0 V maximum at T_J = 25 °C and I_D = 250 μA. This range ensures consistent turn-on behavior with standard 10 V gate drivers while preventing false triggering from noise or leakage currents. The parameter is production-tested and guaranteed across the full operating temperature range of the IRFBC40ASTRLPBF.

Can IRFBC40ASTRLPBF be used in avalanche mode for clamping protection?

Yes, IRFBC40ASTRLPBF is fully rated for repetitive avalanche operation with I_AR = 6.2 A and E_AR = 13 mJ, and single-pulse avalanche energy of E_AS = 570 mJ. These values are tested and guaranteed per the datasheet, allowing intentional use in clamping circuits-such as snubberless flyback or inductive load switching-without requiring external protection components in the IRFBC40ASTRLPBF design.
