Product details

Overview

IRFL9014TR 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, repetitive avalanche capability, and improved thermal performance via enlarged heatsink tab-used in DC-DC converters, load switches, and reverse polarity protection circuits.

For engineers reviewing the IRFL9014TR datasheet, IRFL9014TR pinout, IRFL9014TR application, or IRFL9014TR equivalent, key selection criteria include its -60 V rating, 0.50 Ω on-resistance, 12 nC total gate charge, SOT-223 surface-mount thermal design, and P-channel logic-level compatibility with -10 V gate drive.

Technical Context

This device operates as a high-side switch in low-voltage DC systems, leveraging its negative threshold voltage (-2.0 to -4.0 V) and robust body diode (V_SD = -5.5 V, t_rr = 80–160 ns). Its dynamic dV/dt rating (-4.5 V/ns) and unclamped inductive switching capability (E_AS = 140 mJ) support reliable operation in inductive load environments.

The SOT-223 package provides 40 °C/W junction-to-case thermal resistance and enables >1.25 W power dissipation on standard PCBs. Internal source/drain inductances (L_S = 6.0 nH, L_D = 4.0 nH) are characterized for accurate switching waveform modeling in gate-drive loop design.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V - Maximum blocking voltage for high-side switching in 48 V and lower automotive/industrial rails
R_DS(on)	0.50 Ω @ V_GS = -10 V - Enables <1.1 W conduction loss at -1.8 A, suitable for thermally constrained SMT layouts
Q_g	12 nC - Determines gate driver current requirement (~1.2 A peak for 10 ns rise time), critical for PWM efficiency
I_D (cont)	-1.8 A @ T_C = 25 °C - Continuous current capability with derating to -1.1 A at 100 °C case temperature
E_AS	140 mJ - Single-pulse avalanche energy tolerance supports robustness against inductive kickback without snubbers
t_r/t_f	63 ns / 31 ns - Fast switching transitions reduce switching losses in 100–500 kHz SMPS designs
V_GS(th)	-2.0 to -4.0 V - Confirmed logic-level P-channel operation compatible with standard microcontroller GPIO or level-shifted drivers

Pinout & Package

SOT-223 package with exposed drain tab for thermal conduction; 3-pin configuration (G, D, S) plus integral heatsink pad electrically connected to drain. Standard JEDEC TO-261AA outline (6.30–6.70 mm × 3.30–3.70 mm × 1.55–1.80 mm height).

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control terminal	Accepts negative V_GS to turn on; threshold range -2.0 to -4.0 V ensures reliable turn-on with -5 V logic or -10 V supply
D (Drain)	High-side power input	Connected to exposed metal tab; must be routed to ground plane or heatsink for thermal management and electrical reference
S (Source)	Power output/reference	Connects to load; defines system ground reference when used as high-side switch; carries full load current and body diode reverse recovery

Key Features

Feature	Design Value
Repetitive avalanche rated	Rated for repeated unclamped inductive switching (I_AR = -1.8 A, E_AR = 0.31 mJ), enabling rugged operation without external clamping
Dynamic dV/dt immunity	-4.5 V/ns rated dv/dt prevents false turn-on during fast voltage transients in motor or relay drive applications
Enhanced thermal performance	SOT-223's enlarged drain tab achieves 40 °C/W R_thJC, allowing >1.25 W dissipation on FR-4 PCB without external heatsink
Fast body diode	80–160 ns reverse recovery time and 0.096–0.19 µC Q_rr minimize shoot-through risk and losses in synchronous rectification or H-bridge freewheeling
Surface-mount optimized	Tape-and-reel packaging and pick-and-place compatible footprint simplify automated assembly; Pb-free/halogen-free compliant per Vishay Doc. 99912

FAQ

What is the maximum continuous drain current for IRFL9014TR at 100 °C case temperature?

The IRFL9014TR supports -1.1 A continuous drain current at T_C = 100 °C, per its linear derating factor of 0.025 W/°C from the 3.1 W maximum power dissipation at 25 °C. This value is confirmed in the Absolute Maximum Ratings table of Vishay Document 91195, Rev. G.

Is IRFL9014TR suitable for logic-level gate drive from a 3.3 V microcontroller?

Yes, IRFL9014TR has a gate-source threshold voltage range of -2.0 to -4.0 V, enabling full enhancement with -3.3 V or -5 V logic-level drive. Its R_DS(on) remains well specified at V_GS = -5 V (typical ~0.75 Ω), making it compatible with standard GPIO outputs without level-shifting.

Does IRFL9014TR have an integrated body diode, and what are its key parameters?

Yes, IRFL9014TR includes an intrinsic body diode rated for -1.8 A continuous forward current. Key parameters include V_SD = -5.5 V at -1.8 A and T_J = 25 °C, reverse recovery time t_rr = 80–160 ns, and Q_rr = 0.096–0.19 µC-critical for freewheeling path design in switching regulators and motor drives.

What is the thermal resistance from junction to ambient for IRFL9014TR in standard PCB mount?

When mounted on a 1" square FR-4 PCB, IRFL9014TR exhibits a maximum junction-to-ambient thermal resistance (R_thJA) of 60 °C/W. This value enables ~2.0 W power dissipation at T_A = 25 °C, as specified in the Thermal Resistance Ratings section of the datasheet.

Can IRFL9014TR replace IRFL9110TRPBF in a design?

No-IRFL9014TR (-60 V, 0.50 Ω) is not a direct replacement for IRFL9110TRPBF (-100 V, 0.90 Ω). While both are P-channel SOT-223 MOSFETs, the lower voltage rating of IRFL9014TR makes it unsuitable for 72 V+ systems where IRFL9110TRPBF is deployed; substitution requires validation of voltage margin and thermal performance.
