Product details

Overview

IRFL210PBF from Vishay Siliconix is a 200 V, 0.96 A N-channel surface-mount power MOSFET in SOT-223 package, featuring 1.5 Ω R_DS(on) at V_GS = 10 V, 8.2 nC total gate charge, and repetitive avalanche rating-designed for low-power DC-DC converters, LED drivers, and load-switching circuits.

For engineers reviewing the IRFL210PBF datasheet, IRFL210PBF pinout, IRFL210PBF application, or IRFL210PBF equivalent, key selection criteria include its 200 V drain-source breakdown voltage, thermal performance on PCB mount (R_thJA = 40 °C/W), fast switching (t_r = 17 ns), body diode recovery time (t_rr = 150–310 ns), and lead-free/halogen-free compliance per Vishay's S21-0322-Rev. F specification.

Technical Context

This third-generation power MOSFET uses planar V-groove technology to achieve ruggedized avalanche capability and stable R_DS(on) over temperature (0.30 V/°C coefficient). Its SOT-223 package integrates an enlarged drain tab for enhanced heatsinking-enabling >1.25 W dissipation on standard FR-4 PCBs without external heatsink.

The device supports simple gate drive (V_GS(th) = 2.0–4.0 V), exhibits low dynamic losses (C_iss = 140 pF, C_oss = 53 pF), and is characterized for unclamped inductive switching with E_AS = 50 mJ at T_J = 25 °C-making it suitable for snubberless flyback and relay-driving topologies where transient robustness is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - supports input rails up to 160 V DC with margin for transients in industrial power supplies
R_DS(on) @ V_GS = 10 V	1.5 Ω - enables <1.5 W conduction loss at 0.96 A continuous current
Q_g	8.2 nC - allows efficient 5–12 V gate driving with <1 µs turn-on delay (t_d(on) = 8.2 ns)
I_D (T_C = 25 °C)	0.96 A - defines maximum steady-state current under ideal heatsinking conditions
E_AS	50 mJ - specifies single-pulse avalanche energy handling without failure at T_J = 25 °C
t_rr	150–310 ns - determines minimum dead-time requirements in synchronous rectifier or half-bridge configurations
R_thJA (PCB mount)	40 °C/W - sets thermal rise of 40 °C per watt on 1" square FR-4 board, limiting practical continuous power to ~2.0 W

Pinout & Package

SOT-223 package with exposed drain tab (pin 2) for thermal conduction and mechanical anchoring; standardized 4-pin layout compatible with automated pick-and-place and vapor-phase reflow.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal requiring ≤±20 V bias; low input capacitance (C_iss = 140 pF) minimizes driver loading
2 (D)	Drain	Main high-side power terminal; electrically and thermally connected to large copper tab for PCB heat spreading
3 (S)	Source	Power return path and gate reference; internal source inductance L_S = 6.0 nH affects high-dI/dt switching behavior
4 (S)	Source (redundant)	Second source connection for lower parasitic inductance and improved current sharing in parallel configurations

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables reliable operation under inductive turn-off stress (E_AR = 0.31 mJ) without derating in relay/snubberless designs
Dynamic dV/dt rating	5.0 V/ns immunity prevents false turn-on during high-slew-rate voltage transients in motor or solenoid drives
Fast switching	Combined t_r + t_f = 25.9 ns reduces switching losses below 500 kHz in SMPS applications
Surface-mount SOT-223	Enables compact, automated assembly while delivering >2× thermal performance vs. standard SOT-23 packages
Low Q_gd/Q_g ratio	4.5/8.2 ≈ 55% - improves Miller immunity and hard-switching robustness in high-frequency converters

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
SiHFL210TR-GE3	Same die, identical electrical specs; differs only in tape-and-reel packaging and halogen-free compliance labeling	No functional difference; suitable for same PCB layouts and thermal environments	Select when RoHS/REACH documentation traceability or JEDEC-compliant reel packaging is required
IRFL9110PBF	200 V, but P-channel with −0.96 A rating and higher R_DS(on) (2.5 Ω); complementary topology requirement	Requires high-side gate drive and inverted logic control; not drop-in compatible	Choose only for high-side switching where level-shifting is acceptable and bidirectional blocking is needed

Compared with SiHFL210TR-GE3, IRFL210PBF shares full parametric equivalence but differs in packaging logistics; versus IRFL9110PBF, it offers lower conduction loss and simpler drive but requires low-side configuration-making IRFL210PBF optimal for cost-sensitive, space-constrained DC-DC and load-switching designs.

FAQ

What is the maximum continuous drain current for IRFL210PBF at 100 °C case temperature?

The IRFL210PBF supports 0.6 A continuous drain current at T_C = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the SOT-223 package under real-world PCB mounting conditions-not ambient temperature. Designers must verify junction temperature using R_thJC = 60 °C/W and actual power dissipation to ensure safe operation within the −55 to +150 °C range.

Does IRFL210PBF have avalanche capability, and how is it rated?

Yes, IRFL210PBF is repetitively avalanche rated with E_AR = 0.31 mJ and single-pulse E_AS = 50 mJ at T_J = 25 °C. These values are measured under defined test conditions (V_DD = 50 V, L = 81 mH, I_AS = 0.96 A) and reflect guaranteed energy-handling capacity without device degradation-critical for inductive load switching and snubberless flyback designs where IRFL210PBF serves as the primary power switch.

What is the gate threshold voltage range for IRFL210PBF, and how does it affect drive compatibility?

The IRFL210PBF has a gate-source threshold voltage V_GS(th) of 2.0–4.0 V at I_D = 250 μA, making it compatible with standard 3.3 V and 5 V logic-level drivers. However, full enhancement (R_DS(on) = 1.5 Ω) requires V_GS ≥ 10 V. For reliable saturation in low-voltage systems, designers should confirm gate drive strength and consider the 1.8 nC Q_gs to avoid slow turn-on that could increase switching losses in the IRFL210PBF.

Can IRFL210PBF be paralleled with other units, and what design considerations apply?

Yes, IRFL210PBF is designed for ease of paralleling due to its positive R_DS(on) temperature coefficient and matched threshold characteristics across production lots. To ensure current sharing, use symmetrical PCB layout, individual gate resistors (≤25 Ω), and minimize source inductance differences. The dual-source pin (pins 3 and 4) further reduces loop inductance-critical when paralleling multiple IRFL210PBF units in high-current load-switching applications.

What is the body diode reverse recovery performance of IRFL210PBF, and why does it matter?

The IRFL210PBF body diode exhibits t_rr = 150–310 ns and Q_rr = 0.60–1.4 μC at T_J = 25 °C, IF = 3.3 A, and dI/dt = 100 A/μs. This performance directly impacts switching losses and voltage overshoot in hard-commutated topologies like buck converters or half-bridges. Fast recovery minimizes cross-conduction risk and reduces need for external Schottky catch diodes-enhancing efficiency and reliability in designs where IRFL210PBF operates with intrinsic diode conduction.
