Product details

Overview

IRFL9014PBF from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in SOT-223 package, rated for -60 V drain-source voltage, 0.50 Ω R_DS(on) at V_GS = -10 V, and -1.8 A continuous drain current at T_C = 25 °C. It delivers fast switching (t_r = 63 ns), repetitive avalanche capability (E_AS = 140 mJ), and is optimized for low-voltage DC-DC conversion and load switching in space-constrained industrial controls.

For engineers reviewing the IRFL9014PBF datasheet, IRFL9014PBF pinout, IRFL9014PBF application, or IRFL9014PBF equivalent, key selection criteria include its -60 V V_DS, thermal performance on PCB mount (R_thJA = 60 °C/W), body diode recovery time (t_rr = 80–160 ns), and gate charge profile (Q_g = 12 nC) for driver compatibility and efficiency tuning.

Technical Context

This device operates as a high-side switch in low-power P-channel configurations, leveraging its negative threshold voltage (-2.0 to -4.0 V) and low gate charge to minimize drive losses. Its SOT-223 package integrates an exposed drain tab for direct PCB heatsinking, enabling >2.0 W dissipation with standard FR-4 mounting.

The MOSFET supports unclamped inductive switching with validated repetitive avalanche rating (I_AR = -1.8 A, E_AR = 0.31 mJ) and exhibits robust dV/dt immunity (-4.5 V/ns), making it suitable for relay replacement and motor control snubber circuits where transient resilience is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V - Maximum blocking voltage for high-side switching in 48 V systems
R_DS(on)	0.50 Ω @ V_GS = -10 V - Enables <1.0 W conduction loss at 1.4 A load current
Q_g	12 nC - Determines gate driver current requirement (~24 mA avg. for 500 ns turn-on)
t_r/t_f	63 ns / 31 ns - Supports >1 MHz switching in synchronous buck or OR-ing applications
E_AS	140 mJ - Withstands single-pulse inductive energy without failure in solenoid drivers
T_J Range	-55 to +150 °C - Qualified for extended industrial temperature operation
V_SD	-5.5 V @ I_S = -1.8 A - Body diode forward drop impacts reverse-current path losses

Pinout & Package

SOT-223 package with exposed drain tab (pin 3) for thermal conduction; standard 4-pin configuration with pin 1 = Gate, pin 2 = Source, pin 3 = Drain (tab), pin 4 = Source (dual-source connection).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate terminal	Controls channel conduction; requires -10 V for full enhancement; sensitive to ESD
Pin 2 (S)	Source terminal	Reference node for gate drive; tied to system ground in high-side switch topology
Pin 3 (D)	Drain terminal (exposed tab)	High-voltage output node; tab must be soldered to copper pour for thermal management
Pin 4 (S)	Secondary source connection	Reduces source inductance (L_S = 6.0 nH); improves switching stability in high-dI/dt applications

Key Features

Feature	Design Value
P-channel enhancement mode	Enables high-side switching without level-shifting circuitry in 3.3/5 V logic-controlled systems
Repetitive avalanche rated	Guarantees reliable operation under inductive turn-off stress without external snubbers
Dynamic dV/dt rating (-4.5 V/ns)	Prevents false turn-on during fast voltage transients in noisy industrial environments
SOT-223 thermal design	Delivers 2.0 W power dissipation on 1"² FR-4 PCB-2× higher than standard SOT-23
Fast body diode (t_rr = 80–160 ns)	Reduces reverse-recovery losses in bidirectional current paths like OR-ing and battery backup

FAQ

What is the maximum continuous drain current for IRFL9014PBF at 100 °C case temperature?

The IRFL9014PBF supports -1.1 A continuous drain current at T_C = 100 °C, derated linearly from -1.8 A at 25 °C using a factor of 0.025 W/°C. This reflects its thermal limit under sustained conduction in compact SOT-223 packages mounted on standard PCBs, and must be verified against actual board layout and ambient conditions in final design.

Does IRFL9014PBF require a gate driver IC when controlled by a 3.3 V microcontroller?

No-IRFL9014PBF has a gate threshold voltage range of -2.0 V to -4.0 V, allowing full enhancement with 3.3 V logic high (i.e., V_GS ≈ -3.3 V). However, for optimal R_DS(on) and switching speed, a -10 V gate drive is recommended; use IRFL9014PBF only in 3.3 V systems where moderate on-resistance is acceptable.

Can IRFL9014PBF be used in parallel configurations?

Yes-IRFL9014PBF is explicitly designed for ease of paralleling due to its positive temperature coefficient of R_DS(on), which promotes current sharing across multiple devices. Layout symmetry, matched gate resistors, and shared source routing are required to ensure balanced operation in parallel arrays.

What is the body diode reverse recovery time (t_rr) specification for IRFL9014PBF?

The IRFL9014PBF body diode exhibits t_rr = 80–160 ns under test conditions of T_J = 25 °C, I_F = -6.7 A, and dI/dt = 100 A/μs. This fast recovery enables efficient operation in bidirectional current paths such as OR-ing circuits and battery backup systems where reverse conduction occurs.

Is IRFL9014PBF suitable for avalanche energy handling in inductive load switching?

Yes-IRFL9014PBF is repetitively avalanche rated with E_AR = 0.31 mJ and single-pulse E_AS = 140 mJ. These values are validated per JEDEC standards using unclamped inductive test circuits, confirming its suitability for solenoid, relay, and small motor drive applications without external clamping components.
