Product details

Overview

IRFR110TRLPBF-BE3 from Vishay Siliconix is a 100 V, 4.3 A N-channel surface-mount power MOSFET in DPAK (TO-252) package, featuring 0.54 Ω R_DS(on) at V_GS = 10 V, 8.3 nC total gate charge, and repetitive avalanche rating-designed for DC-DC converters, motor control, and load switching in industrial power supplies.

For engineers reviewing the IRFR110TRLPBF-BE3 datasheet, IRFR110TRLPBF-BE3 pinout, IRFR110TRLPBF-BE3 application, or IRFR110TRLPBF-BE3 equivalent, this page delivers verified electrical specs, thermal derating behavior, body diode recovery performance (t_rr = 100–200 ns), PCB-mount power dissipation (2.5 W), and real-world switching timing (t_d(on) = 6.9 ns, t_f = 9.4 ns).

Technical Context

This third-generation TrenchFET® MOSFET uses planar silicon process to achieve low conduction loss and fast switching with controlled dV/dt (5.5 V/ns peak diode recovery). Its ruggedized design supports unclamped inductive switching with 75 mJ single-pulse avalanche energy and 2.5 mJ repetitive avalanche energy.

The device operates across -55 °C to +150 °C junction temperature, features ±20 V gate-source voltage rating, and integrates a low-V_SD (2.5 V max) intrinsic body diode optimized for synchronous rectification and freewheeling in buck topologies.

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
IRLR110TRPBF	Same V_DS (100 V), lower R_DS(on) (0.39 Ω), higher Q_g (11.5 nC), same DPAK package	Better conduction efficiency but slower switching; suited for <200 kHz applications where loss balance favors R_DS(on)	Select when thermal budget is constrained and switching frequency is ≤150 kHz
SiHF110-GE3	Identical R_DS(on) (0.54 Ω), same Q_g (8.3 nC), identical avalanche ratings, same DPAK footprint	Drop-in replacement with identical electrical and thermal behavior; differs only in halogen-free material compliance	Choose for RoHS+halogen-free compliance requirements without circuit redesign

Compared with IRFR110TRLPBF-BE3, IRLR110TRPBF trades higher gate charge for lower on-resistance-favoring low-frequency, high-current use cases-while SiHF110-GE3 matches all key parameters exactly but adds halogen-free certification, making it a direct compliance-driven alternative.

FAQ

What is the maximum continuous drain current for IRFR110TRLPBF-BE3 at 100 °C case temperature?

The IRFR110TRLPBF-BE3 supports 2.7 A continuous drain current at T_C = 100 °C, per its absolute maximum ratings table. This value reflects linear derating from 4.3 A at 25 °C using a factor of 0.20 W/°C, and assumes proper PCB copper area for thermal conduction. Exceeding this current risks exceeding the 150 °C maximum junction temperature.

Does IRFR110TRLPBF-BE3 have a specified body diode reverse recovery charge (Q_rr)?

Yes, the IRFR110TRLPBF-BE3 specifies Q_rr = 0.44–0.88 μC under test conditions of T_J = 25 °C, I_F = 5.6 A, and dI/dt = 100 A/μs. This parameter directly impacts switching loss in synchronous rectifier and freewheeling applications and is measured with the integral body diode-not an external component.

Is IRFR110TRLPBF-BE3 suitable for avalanche operation in unclamped inductive switching?

Yes, the IRFR110TRLPBF-BE3 is explicitly rated for repetitive avalanche operation with I_AR = 4.3 A and E_AR = 2.5 mJ, and single-pulse avalanche energy of 75 mJ. These values are validated per Figure 12 and note "a" in the datasheet, confirming robustness in relay driving, solenoid control, and snubberless flyback designs.

What is the thermal resistance from junction to ambient for IRFR110TRLPBF-BE3 when mounted on a 1" square FR-4 PCB?

When mounted on a 1" square FR-4 PCB (per note "e"), the IRFR110TRLPBF-BE3 has R_thJA = 50 °C/W. This value enables calculation of junction temperature rise: for example, at 2.5 W dissipation, ΔT = 125 °C, resulting in T_J = 150 °C at 25 °C ambient-matching its maximum rated junction temperature.

What does the "-BE3" suffix indicate in IRFR110TRLPBF-BE3?

The "-BE3" suffix in IRFR110TRLPBF-BE3 denotes an alternate manufacturing location and confirms lead (Pb)-free and halogen-free compliance per Vishay's material categorization standard (document 99912). It does not alter electrical specifications, package dimensions, or reliability performance versus non-BE3 variants like IRFR110TRLPbF.
