Product details

Overview

IRFL214TRPBF from Vishay Siliconix is a 250 V, 0.79 A N-channel surface-mount power MOSFET in SOT-223 package, with R_DS(on) = 2.0 Ω at V_GS = 10 V, Q_g = 8.2 nC, and repetitive avalanche rating. It serves as a low-power switching element in DC-DC converters, LED drivers, and load-switching circuits where compact size and thermal robustness are critical.

For engineers reviewing the IRFL214TRPBF datasheet, IRFL214TRPBF pinout, IRFL214TRPBF application, or IRFL214TRPBF equivalent, key selection criteria include its 250 V drain-source breakdown voltage, 2.0 Ω on-resistance at 10 V gate drive, 8.2 nC total gate charge, SOT-223 thermal performance (2.0 W PCB mount), and avalanche energy rating of 50 mJ (single-pulse).

Technical Context

This device belongs to Vishay's third-generation high-voltage power MOSFET family, optimized for fast switching and ruggedized operation. Its design integrates dynamic dV/dt immunity (4.8 V/ns), repetitive avalanche capability (0.31 mJ), and low gate charge (Q_gd = 4.5 nC) to support reliable hard-switching in inductive loads.

The SOT-223 package features an enlarged drain tab for enhanced heatsinking-enabling >1.25 W dissipation on FR-4 PCBs-and supports automated pick-and-place assembly. Internal source/drain inductances (L_S = 6.0 nH, L_D = 4.0 nH) are specified to aid layout-aware switching analysis.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	250 V - Supports primary-side switching in offline flyback or auxiliary supplies up to 200 V DC bus.
R_DS(on)	2.0 Ω @ V_GS = 10 V - Delivers ≤0.47 A continuous current with <1.0 W conduction loss at room temperature.
Q_g	8.2 nC - Enables efficient 100–500 kHz switching with standard gate drivers (e.g., TC442x) without excessive drive power.
E_AS	50 mJ - Withstands unclamped inductive energy transients in relay/snubberless solenoid drivers.
T_J Range	−55 °C to +150 °C - Qualified for industrial ambient environments and thermally constrained enclosures.
R_thJA	60 °C/W (PCB mount) - Limits junction rise to ~120 °C at 2.0 W dissipation on 1"² FR-4 board.

Pinout & Package

SOT-223 package with exposed drain tab (pin 2) for thermal conduction and mechanical anchoring. Standard 4-pin configuration: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source, Pin 4 = Source (dual-source connection).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate terminal	High-impedance control input requiring ≤100 nA leakage; driven by logic-level or dedicated gate driver.
Pin 2 (D)	Drain terminal / thermal pad	Primary high-voltage node and main thermal path; must be soldered to copper pour for rated power handling.
Pins 3 & 4 (S)	Source terminals	Low-side return path; dual-source pins reduce source inductance and improve switching stability.

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables reliable operation under transient overloads (e.g., motor stall, inductive kickback) without derating or external clamping.
Dynamic dV/dt rating	4.8 V/ns immunity prevents false turn-on during high-speed voltage transitions in noisy power stages.
Fast switching	7.0 ns turn-on delay + 7.6 ns rise time enables clean edge control in PWM dimming and SMPS applications.
Easy paralleling	Positive temperature coefficient of R_DS(on) ensures current sharing across multiple IRFL214TRPBF devices without ballast resistors.

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 package; identical R_DS(on), Q_g, and avalanche specs.	No functional difference; qualified for RoHS-compliant manufacturing with alternate tape/reel packaging.	Select when full halogen-free compliance and Vishay's "-GE3" traceability are required.
IRFL9110TRPBF	Lower V_DS (100 V), higher R_DS(on) (3.5 Ω), same SOT-223 footprint and gate drive profile.	Not suitable for >120 V applications; better for 12–24 V systems where lower cost and reduced voltage stress are priorities.	Choose only for low-voltage, high-current scenarios where 250 V margin is unnecessary.

Compared with SiHFL214TR-GE3, IRFL214TRPBF offers identical electrical performance but differs in lead finish and manufacturing location ("-BE3"); versus IRFL9110TRPBF, it provides 2.5× higher voltage rating at the expense of slightly higher on-resistance-making it optimal for universal-input auxiliary supplies and industrial 24–48 V systems.

FAQ

What is the maximum continuous drain current for IRFL214TRPBF at 100 °C case temperature?

The maximum continuous drain current for IRFL214TRPBF is 0.50 A at T_C = 100 °C, per the Absolute Maximum Ratings table. This derating reflects thermal limits of the SOT-223 package under sustained power dissipation; operation above this current requires active cooling or reduced duty cycle to maintain T_J ≤ 150 °C. The IRFL214TRPBF datasheet specifies linear derating of 0.025 W/°C above 25 °C case temperature.

Does IRFL214TRPBF have a built-in body diode, and what are its key parameters?

Yes, IRFL214TRPBF includes an integral body diode with V_SD = 2.0 V at I_S = 0.79 A and T_J = 25 °C, reverse recovery time t_rr = 190–390 ns, and Q_rr = 0.64–1.3 μC. These values are measured under standardized conditions (I_F = 2.7 A, dI/dt = 100 A/μs) and support synchronous rectification or freewheeling in low-frequency switching topologies. The IRFL214TRPBF body diode is not optimized for high-frequency ZVS operation.

Can IRFL214TRPBF be used with 5 V logic-level gate drive?

No-IRFL214TRPBF is not a logic-level MOSFET. Its gate threshold voltage V_GS(th) ranges from 2.0 V to 4.0 V, and R_DS(on) is specified at V_GS = 10 V (2.0 Ω). At 5 V gate drive, R_DS(on) increases significantly (>5 Ω), causing excessive conduction loss. For 5 V control, consider Vishay's Si2300 or similar logic-level alternatives-not the IRFL214TRPBF.

What is the thermal resistance from junction to ambient for IRFL214TRPBF on a standard PCB?

The maximum junction-to-ambient thermal resistance (R_thJA) for IRFL214TRPBF is 60 °C/W when mounted on a 1" square FR-4 PCB, per the Thermal Resistance Ratings table. This value assumes no additional heatsink; actual performance depends on copper area, layer count, and airflow. The IRFL214TRPBF achieves 2.0 W power dissipation under these conditions, making it suitable for thermally constrained layouts where larger packages are impractical.

Is IRFL214TRPBF suitable for avalanche energy handling in unclamped inductive switching?

Yes-IRFL214TRPBF is explicitly rated for repetitive avalanche operation with E_AR = 0.31 mJ and single-pulse E_AS = 50 mJ. These ratings are validated per JEDEC test conditions (L = 128 mH, I_AS = 0.79 A, V_DD = 50 V). Designers must ensure pulse width and duty cycle remain within limits shown in Figure 11 to avoid exceeding T_J(max) = 150 °C. The IRFL214TRPBF datasheet confirms this capability in both absolute maximum and avalanche test notes.
