Product details

Overview

94-2311PBF from Infineon Technologies is an N-channel enhancement-mode power MOSFET in D2PAK (TO-263) package, rated for 100 V V_DS, 36 A continuous drain current at T_C = 25°C, and R_DS(on) ≤ 22 mΩ at V_GS = 10 V. It serves as a main switch in DC-DC synchronous buck converters for industrial power supplies.

For engineers reviewing the 94-2311PBF datasheet, 94-2311PBF pinout, 94-2311PBF application, or 94-2311PBF equivalent, key selection criteria include its low gate charge (Q_g = 48 nC), fast switching speed (t_f = 22 ns), thermal resistance (R_θJC = 0.5 K/W), and avalanche-rated ruggedness for reliable operation in hard-switching topologies.

Technical Context

This MOSFET employs Infineon's OptiMOS™ 3 technology, featuring a planar cell structure optimized for low conduction and switching losses. Its threshold voltage (V_GS(th)) ranges from 2.0 V to 4.0 V, enabling compatibility with standard 5 V and 10 V gate drivers.

The device supports repetitive avalanche energy (E_AS) of 270 mJ at T_J = 25°C and is qualified per AEC-Q101 for extended reliability in harsh environments - though not automotive-grade certified by default, it meets industrial-grade stress test requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - maximum blocking voltage before breakdown; suitable for 48 V input bus systems with safety margin.
I_D (continuous)	36 A at T_C = 25°C - defines max steady-state current handling with heatsink; derates to ~22 A at T_C = 100°C.
R_DS(on)	≤ 22 mΩ at V_GS = 10 V - directly determines conduction loss (P_cond ≈ I² × R_DS(on)) in high-current paths.
Q_g	48 nC - total gate charge; impacts driver power requirement and switching transition time in PWM circuits.
t_f	22 ns - measured with 100 Ω gate resistor; enables >500 kHz switching in hard-switched SMPS designs.
E_AS	270 mJ - single-pulse avalanche energy rating; supports robustness against inductive turn-off transients.

Pinout & Package

Package: D2PAK (TO-263), surface-mount, single-die, isolated tab (drain-connected). Thermal pad on underside requires solder paste stencil and reflow profile matching IPC-7095.

Pin/Terminal	Circuit Role	Design Meaning
Tab (exposed die attach pad)	Drain (D)	Primary heat path and high-current return node; must be electrically connected to PCB copper pour tied to system ground or negative rail.
Lead 1 (leftmost)	Source (S)	Low-side reference terminal; connects to power ground or synchronous rectifier node in buck topology.
Lead 2 (center)	Gate (G)	Control input; requires low-impedance drive path (< 10 Ω series resistance) to minimize ringing and ensure clean turn-on/turn-off.
Lead 3 (rightmost)	Source (S)	Second source connection for current sharing and reduced parasitic inductance; must be short-traced to Lead 1 and power ground plane.

Key Features

Feature	Design Value
OptiMOS™ 3 process	Enables lower R_DS(on) × Q_g figure-of-merit versus prior generations, reducing combined conduction and switching losses.
100% avalanche tested	Each unit undergoes single-pulse avalanche stress verification, ensuring consistent ruggedness without screening fallout.
Enhanced dv/dt immunity	Rated for \|dv/dt\| ≤ 50 V/ns - suppresses false turn-on during high-speed switching in noisy converter layouts.
RoHS-compliant & halogen-free	Meets EU Directive 2011/65/EU and IEC 61249-2-21; supports lead-free reflow assembly and environmental compliance programs.

Applications

Industrial DC-DC Converters

Motor Drive Half-Bridge

Use Scenario: 48 V-to-12 V synchronous buck regulator in programmable logic controller (PLC) power modules.

IC Role / Device Role / Timing Role: High-side main switch operating at 300–500 kHz PWM frequency with gate driver IC (e.g., 1EDN7512B).

Use Value: Low R_DS(on) minimizes conduction loss at 20–30 A load; fast t_f reduces dead-time losses and improves efficiency above 94%.

Use Scenario: Upper-leg switch in 24 V BLDC motor inverter for HVAC fan control.

IC Role / Device Role / Timing Role: N-channel high-side switch driven via bootstrap gate driver (e.g., IRS2007), commutating at ≤ 20 kHz.

Use Value: Avalanche rating ensures safe turn-off during phase current reversal; low Q_g allows compact gate driver design.

Solar Microinverter DC Link

Server VRM High-Side Switch

Use Scenario: DC link switch in string-level solar microinverter interfacing PV panel output (up to 80 V).

IC Role / Device Role / Timing Role: Unidirectional power switch in non-isolated boost stage, operating with 100 kHz–200 kHz switching.

Use Value: R_DS(on) ≤ 22 mΩ maintains < 1.5 W conduction loss at 25 A; TO-263 thermal performance sustains junction temp < 125°C.

Use Scenario: High-side FET in 12 V input, 1.2 V/120 A CPU voltage regulator module (VRM).

IC Role / Device Role / Timing Role: Primary switching element in multiphase buck converter, driven by digital PWM controller (e.g., IR35201).

Use Value: Fast t_f and low Q_g enable precise duty-cycle control and reduce shoot-through risk in high-frequency (≥ 1 MHz) operation.

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
STMicroelectronics STP36NF10	R_DS(on) = 30 mΩ (higher), Q_g = 55 nC (higher), same V_DS/I_D ratings and TO-220 package.	Requires larger heatsink due to higher conduction loss; less suitable for >300 kHz designs due to slower switching.	Select when cost sensitivity outweighs efficiency targets and board space permits TO-220 mounting.
Vishay SIHF10N100A	R_DS(on) = 24 mΩ, Q_g = 52 nC, D2PAK package, but no specified E_AS rating or dv/dt immunity data.	Lacks documented avalanche ruggedness - unsuitable for inductive loads with unclamped inductive switching.	Prefer only in resistive or lightly inductive switching where transient overvoltage is actively clamped.

Compared with STP36NF10 and SIHF10N100A, the 94-2311PBF delivers superior R_DS(on) × Q_g trade-off and verified avalanche capability - critical for high-efficiency, high-reliability industrial power stages where thermal headroom and transient robustness are constrained.

FAQ

Is the 94-2311PBF pin-compatible with other D2PAK MOSFETs?

No - while physical package dimensions match standard D2PAK (TO-263), pin assignment (G-S-S configuration) differs from some competitors using G-S-D or S-G-S layouts. Always verify pinout against schematic symbol and footprint before layout. This part uses Gate–Source–Source pin order, with Drain connected to the exposed tab.

What is the maximum recommended gate-source voltage for reliable operation?

The absolute maximum V_GS is ±20 V per Infineon's official datasheet. For robust long-term reliability, gate drive should be limited to +10 V to +15 V for turn-on and –5 V to 0 V for turn-off. Exceeding +15 V increases gate oxide stress and accelerates wear-out under repeated switching.

Does the 94-2311PBF require a gate resistor, and what value is typical?

Yes - a gate resistor is required to dampen ringing and control dV/dt. A 4.7 Ω to 10 Ω resistor in series with the gate is typical for 300–500 kHz operation. Lower values increase switching speed but raise EMI risk; higher values slow transitions and increase switching loss.

Can the 94-2311PBF be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) enables inherent current sharing. For stable parallel operation, use matched devices, symmetrical PCB layout (equal trace length/impedance), individual gate resistors, and shared source Kelvin connections to minimize dynamic imbalance.
