Product details

Overview

IRFBC20PBF-BE3 from Vishay Siliconix is a 600 V, 2.2 A N-channel power MOSFET in TO-220AB package, featuring 4.4 Ω R_DS(on) at V_GS = 10 V, 18 nC total gate charge, and repetitive avalanche rating up to 2.2 A - designed for high-voltage flyback and offline SMPS primary-side switching.

For engineers reviewing the IRFBC20PBF-BE3 datasheet, IRFBC20PBF-BE3 pinout, IRFBC20PBF-BE3 application, or IRFBC20PBF-BE3 equivalent, key selection criteria include its 600 V blocking capability, low gate charge for efficient hard-switching, rugged unclamped inductive switching performance, and RoHS-compliant/halogen-free construction per Vishay S21-0868-Rev. C.

Technical Context

This third-generation planar vertical power MOSFET uses a ruggedized die design with dynamic dV/dt immunity (3.0 V/ns) and built-in body diode optimized for snubberless operation in discontinuous conduction mode (DCM) flyback converters. Its 2.5 °C/W junction-to-case thermal resistance enables reliable 50 W dissipation at TC = 25 °C.

The device supports simple gate drive (±20 V V_GS rating, 3.0 nC Q_gs) and parallel operation due to positive temperature coefficient of R_DS(on). Avalanche energy handling (84 mJ single-pulse, 5.0 mJ repetitive) is validated under defined test conditions (L = 31 mH, I_AS = 2.2 A).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports primary-side switching in universal-input (85–265 V_AC) offline power supplies without derating.
R_DS(on) @ V_GS = 10 V	4.4 Ω - determines conduction loss in high-voltage, low-current SMPS stages; enables <2.2 A continuous operation at TC = 25 °C.
Q_g	18 nC - defines gate drive power requirement and switching speed; compatible with standard PWM controllers driving ≤20 nC loads.
E_AS	84 mJ - quantifies single-pulse avalanche robustness during transformer leakage energy discharge in flyback topologies.
dV/dt Rating	3.0 V/ns - ensures immunity to false turn-on during high dv/dt transients in high-frequency, high-voltage switching nodes.
T_J Range	–55 to +150 °C - supports operation in industrial ambient environments and sealed power enclosures with limited airflow.

Pinout & Package

IRFBC20PBF-BE3 is housed in a through-hole TO-220AB package with isolated tab (drain-connected), standardized mounting footprint, and 1.1 N·m screw torque specification. Thermal interface requires flat, greased heatsink surface (R_thCS = 0.50 °C/W typical).

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Receives 10 V logic-level gate drive; input capacitance (C_iss = 350 pF) shapes Miller plateau timing.
D (Drain)	High-voltage output terminal	Connected to transformer primary and HV rail; electrically tied to metal tab for direct heatsinking.
S (Source)	Power return and reference node	Serves as current sense point and gate drive return; internal source inductance (L_S = 7.5 nH) affects diode recovery behavior.

Key Features

Feature	Design Value
Repetitive avalanche rated	Validated for 2.2 A I_AR and 5.0 mJ E_AR, enabling reliable operation under transient overloads without external clamping.
Dynamic dV/dt immunity	3.0 V/ns rating prevents spurious turn-on during fast voltage transitions in high-side switching configurations.
Low Q_gd/Q_g ratio	Q_gd = 8.9 nC / Q_g = 18 nC ≈ 49% - reduces Miller-induced switching delay and improves controllability in hard-switched topologies.
RoHS-compliant & halogen-free	IRFBC20PBF-BE3 meets JEDEC JS709C and IPC-1752A requirements, eliminating brominated flame retardants and lead.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP6NK60ZFP	600 V, 5.5 Ω R_DS(on), 16 nC Q_g, SuperFET II technology	Higher R_DS(on) increases conduction loss but lower Q_g improves light-load efficiency	Prefer when optimizing for no-load power consumption over full-load thermal margin
IXTP2N60P	600 V, 5.2 Ω R_DS(on), 22 nC Q_g, PolarHT process	Higher gate charge demands stronger driver; wider SOA supports higher pulse currents	Prefer when designing for intermittent overload tolerance in motor control auxiliary supplies

Compared with STP6NK60ZFP and IXTP2N60P, IRFBC20PBF-BE3 offers the lowest R_DS(on) (4.4 Ω) among these 600 V devices, delivering superior full-load conduction efficiency in space-constrained adapters, while maintaining balanced gate drive demand and proven avalanche ruggedness in production flyback designs.

FAQ

What is the maximum continuous drain current for IRFBC20PBF-BE3 at 100 °C case temperature?

The IRFBC20PBF-BE3 supports 1.4 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-220AB package and must be verified against actual heatsink performance and ambient conditions in the final layout. The IRFBC20PBF-BE3 datasheet (S21-0868-Rev. C) confirms this value under steady-state conduction with proper thermal management.

Does IRFBC20PBF-BE3 have a fully rated body diode for freewheeling applications?

Yes, the IRFBC20PBF-BE3 integrates a robust body diode rated for 2.2 A continuous source-drain current and 8.0 A pulsed current. Its reverse recovery time (trr = 290–580 ns) and charge (Qrr = 0.67–1.3 μC) are characterized at TJ = 25 °C, IS = 2.0 A, and dI/dt = 100 A/μs. The IRFBC20PBF-BE3 body diode is suitable for DCM flyback freewheeling but not recommended for high-frequency synchronous rectification.

Is IRFBC20PBF-BE3 pin-compatible with earlier IRFBC20 variants like IRFBC20PbF?

Yes, IRFBC20PBF-BE3 is mechanically and electrically pin-compatible with IRFBC20PbF and other TO-220AB-packaged variants in the IRFBC20 family. Both share identical pinout (G-D-S), thermal pad configuration, and electrical specifications. The IRFBC20PBF-BE3 differs only in material content: it is lead-free and halogen-free per JEDEC JS709C, whereas IRFBC20PbF is lead-free but not halogen-free.

What is the gate threshold voltage range for IRFBC20PBF-BE3?

The gate-source threshold voltage (VGS(th)) for IRFBC20PBF-BE3 is specified from 2.0 V to 4.0 V at VDS = VGS and ID = 250 μA. This range indicates standard-level gate drive compatibility - the IRFBC20PBF-BE3 requires ≥10 V VGS for full enhancement and minimal RDS(on), and is not a logic-level MOSFET. The IRFBC20PBF-BE3 operates reliably within this threshold window across its –55 to +150 °C junction temperature range.

Can IRFBC20PBF-BE3 be used in parallel configurations?

Yes, IRFBC20PBF-BE3 supports paralleling due to its positive temperature coefficient of RDS(on), which promotes current sharing under thermal imbalance. Vishay explicitly lists "Ease of paralleling" as a feature. Successful implementation requires matched gate drive impedance, symmetrical PCB layout, and shared heatsinking. The IRFBC20PBF-BE3's 3.0 nC Qgs and 8.9 nC Qgd help minimize gate oscillation risk during parallel switching.
