Product details

Overview

IRFR9110TRL from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in DPAK (TO-252) surface-mount package, rated for -100 V drain-source voltage, 1.2 Ω R_DS(on) at V_GS = -10 V, and -3.1 A continuous drain current at T_C = 25 °C. It delivers fast switching with 8.7 nC total gate charge and supports repetitive avalanche operation up to 2.5 mJ, making it suitable for DC-DC converter high-side switches and motor control H-bridge circuits.

For engineers reviewing the IRFR9110TRL datasheet, IRFR9110TRL pinout, IRFR9110TRL application, or IRFR9110TRL equivalent, key selection considerations include its -100 V blocking capability, thermal performance on PCB mount (R_thJA = 50 °C/W), body diode recovery time (80–160 ns), and compatibility with standard DPAK footprint layouts per Vishay's recommended pad dimensions.

Technical Context

This device employs third-generation trench-gate silicon technology optimized for ruggedness and low conduction loss. Its dynamic dV/dt rating (-5.5 V/ns) and repetitive avalanche capability enable reliable operation in inductive switching environments without external snubbers.

The IRFR9110TRL integrates a monolithic body diode with V_SD = -5.5 V at I_S = -3.1 A and Q_rr = 0.17–0.30 μC, supporting synchronous rectification and freewheeling functions in buck and half-bridge topologies where controlled reverse recovery is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-100 V - Supports high-voltage DC bus isolation in industrial power supplies and automotive battery management systems.
R_DS(on)	1.2 Ω @ V_GS = -10 V - Enables <1.2 W conduction loss at -3.1 A, suitable for thermally constrained PCB-mounted designs.
Q_g	8.7 nC - Low gate charge reduces driver power requirement and enables efficient 100–500 kHz switching in SMPS.
I_D (cont.)	-3.1 A @ T_C = 25 °C - Specifies maximum steady-state current under heatsink-cooled conditions.
E_AS	140 mJ - Single-pulse avalanche energy rating allows safe unclamped inductive turn-off in motor drive fault conditions.
R_thJA (PCB)	50 °C/W - Thermal resistance when mounted on 1" FR-4 PCB defines junction temperature rise under 2.5 W dissipation.
t_rr	80–160 ns - Body diode reverse recovery time impacts EMI and efficiency in hard-switched converters.

Pinout & Package

DPAK (TO-252) surface-mount package with exposed drain pad for thermal conduction; standardized 3-pin layout compatible with IPC-7351B footprint.

Pin/Terminal	Circuit Role	Design Meaning

Pin 2 (Gate)	Control electrode	Accepts negative gate voltage relative to source to turn on; requires -10 V for full R_DS(on) specification.
Pin 3 (Drain)	Power output terminal	Exposed metal pad on underside - must be soldered to large copper pour for thermal management and current path.

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables robust operation during transient overloads without derating or external protection in motor control and UPS applications.
Dynamic dV/dt rating	-5.5 V/ns immunity prevents spurious turn-on due to high-speed voltage transients in noisy industrial environments.
Fast switching with low Q_g	8.7 nC total gate charge supports efficient high-frequency operation while minimizing driver losses.
Surface-mount DPAK package	TO-252 outline enables automated assembly and provides superior thermal performance vs. through-hole alternatives like IRFU9110.

FAQ

What is the maximum continuous drain current for IRFR9110TRL at 100 °C case temperature?

The IRFR9110TRL supports -2.0 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package under sustained power dissipation; designers must verify junction temperature using R_thJC = 5.0 °C/W and actual power loss to ensure T_J remains ≤150 °C.

Does IRFR9110TRL have a specified body diode reverse recovery time?

Yes, the IRFR9110TRL specifies body diode reverse recovery time (t_rr) as 80–160 ns at T_J = 25 °C, I_F = -4.0 A, and dI/dt = 100 A/μs. This parameter is critical for estimating switching losses and EMI in freewheeling applications; actual values vary with temperature and current slew rate.

Can IRFR9110TRL be used in linear mode for constant-current regulation?

Yes, the IRFR9110TRL is rated for linear operation with maximum power dissipation of 2.5 W on PCB mount (T_A = 25 °C) and R_thJA = 50 °C/W. When used as a current sink, ensure gate drive maintains V_GS within ±20 V and monitor T_J to avoid exceeding 150 °C, especially under high V_DS × I_D conditions.

What is the gate threshold voltage range for IRFR9110TRL?

The IRFR9110TRL has a gate-source threshold voltage (V_GS(th)) range of -2.0 V to -4.0 V at V_DS = V_GS and I_D = 250 μA. This negative threshold confirms its P-channel enhancement-mode behavior; logic-level drive requires gate voltage ≤ -2.0 V relative to source to initiate conduction.

Is IRFR9110TRL pin-compatible with IRFU9110?

No, IRFR9110TRL uses the DPAK (TO-252) surface-mount package with three leads in straight-line configuration, while IRFU9110 uses the IPAK (TO-251) through-hole package with bent leads. Although both share identical die characteristics, their mechanical footprints and mounting methods differ - PCB layout and assembly processes are not interchangeable.
