Product details

Overview

IRFL214PBF from Vishay Siliconix is a 250 V, 0.79 A N-channel surface-mount power MOSFET in SOT-223 package, featuring 2.0 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 where thermal performance on FR-4 PCBs is critical.

For engineers reviewing the IRFL214PBF datasheet, IRFL214PBF pinout, IRFL214PBF application, or IRFL214PBF equivalent, key selection criteria include its 250 V drain-source breakdown voltage, 3.1 W maximum power dissipation at T_C = 25 °C, 190–390 ns body diode reverse recovery time, and SOT-223 thermal design compatibility with standard pick-and-place assembly.

Technical Context

This N-channel enhancement-mode MOSFET uses planar silicon technology optimized for fast switching and ruggedized unclamped inductive switching. Its gate threshold voltage (2.0–4.0 V) ensures reliable turn-on with standard 10 V logic-level drive, while dynamic dV/dt rating of 4.8 V/ns supports stable operation in noisy environments.

The device integrates a monolithic body diode with 2.0 V forward drop at 0.79 A and 190–390 ns reverse recovery time, enabling synchronous rectification in low-duty-cycle topologies. Thermal resistance of 40 °C/W (junction-to-case) and 60 °C/W (junction-to-ambient, PCB mount) defines its derating behavior under continuous conduction mode.

I_D (continuous)	0.79 A @ T_C = 25 °C - defines maximum steady-state current before thermal shutdown on standard 1"² FR-4 board
E_AS	50 mJ - withstands single-pulse inductive energy without failure in relay or solenoid drive applications

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
SiHFL214TR-GE3	Same die, Pb-free/halogen-free SOT-223 packaging; identical R_DS(on), Q_g, and avalanche ratings	No functional difference; preferred for RoHS-compliant production with tape-and-reel delivery	Select SiHFL214TR-GE3 when lead-free compliance and JEDEC-standard packaging are required
IRFL9110PBF	200 V V_DS, 1.2 Ω R_DS(on), 12 nC Q_g; lower voltage rating but lower on-resistance and higher gate charge	Better for ≤150 V systems needing lower conduction loss; less suitable for 200+ V transient-prone inputs	Choose IRFL9110PBF only if system max V_DS stays below 180 V and gate drive strength supports 12 nC

Compared with IRFL214PBF, SiHFL214TR-GE3 offers identical electrical performance with enhanced environmental compliance, while IRFL9110PBF trades voltage headroom for lower R_DS(on)-making IRFL214PBF optimal for 200–250 V industrial and automotive auxiliary power applications requiring ruggedness over raw efficiency.

FAQ

What is the maximum continuous drain current for IRFL214PBF at 100 °C case temperature?

The IRFL214PBF supports 0.50 A continuous drain current at T_C = 100 °C, per its absolute maximum ratings table. This derating reflects thermal limitations of the SOT-223 package on standard PCBs; actual usable current depends on layout, copper area, and ambient airflow. The IRFL214PBF must be operated within this limit to avoid junction temperature exceeding 150 °C.

Does IRFL214PBF have a built-in body diode, and what are its key parameters?

Yes, the IRFL214PBF integrates a monolithic body diode with 2.0 V forward voltage at 0.79 A and 190–390 ns reverse recovery time (T_J = 25 °C). Its reverse recovery charge is 0.64–1.3 μC. These values are measured under specified test conditions and define freewheeling behavior in buck or flyback topologies using the IRFL214PBF.

Is IRFL214PBF suitable for avalanche operation, and what energy level is rated?

The IRFL214PBF is repetitively avalanche rated with 0.31 mJ maximum repetitive avalanche energy and 50 mJ single-pulse avalanche energy. These values are validated per Vishay's unclamped inductive switching test (Fig. 12), confirming the IRFL214PBF can safely absorb inductive kickback in relay, solenoid, or motor gate-drive applications without external protection.

What is the gate threshold voltage range for IRFL214PBF, and how does it affect drive requirements?

The IRFL214PBF has a gate threshold voltage range of 2.0 V to 4.0 V at I_D = 250 μA. This allows reliable turn-on with 5 V logic (marginally) but is optimized for 10 V gate drive to achieve full R_DS(on) = 2.0 Ω. Using 5 V may result in higher on-resistance and thermal stress; thus, the IRFL214PBF should be driven with ≥8 V for robust conduction.

Can IRFL214PBF be paralleled with other devices, and what design considerations apply?

Yes, the IRFL214PBF is designed for ease of paralleling due to positive temperature coefficient of R_DS(on), which promotes current sharing. To parallel multiple IRFL214PBF units, use matched gate resistors, symmetrical PCB layout, and individual source resistors for current sensing. Thermal coupling between devices must be minimized to prevent thermal runaway-each IRFL214PBF requires independent heatsinking or spaced mounting.
