Product details

Overview

IRL3215 from International Rectifier is a 150V, 12A N-channel enhancement-mode Power MOSFET in TO-220AB package, optimized for high-efficiency DC-DC conversion and motor control. It features 0.166Ω R_DS(on) at V_GS = 10V, 130mJ single-pulse avalanche energy rating, and fast switching (t_r = 45ns, t_f = 36ns), enabling robust operation in industrial power supplies and brushless DC motor drives.

For engineers reviewing the IRL3215 datasheet, IRL3215 pinout, IRL3215 application, or IRL3215 equivalent, key selection criteria include its 150V V_DS, 0.166Ω on-resistance at 10V gate drive, TO-220AB thermal resistance (R_θJC = 1.9°C/W), avalanche ruggedness, and body diode recovery characteristics (t_rr = 160–240ns).

Technical Context

The IRL3215 employs Fifth Generation HEXFET process technology to achieve ultra-low on-resistance per die area while maintaining high voltage blocking capability. Its gate threshold voltage (1.0–2.0V) enables direct logic-level drive from 3.3V/5V microcontrollers without level-shifting.

It integrates a fully rated intrinsic body diode with 7.2A continuous source current capability and 1.3V forward voltage at 7.2A, supporting synchronous rectification and bidirectional current handling in H-bridge topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	150V - supports input rails up to 120V DC with margin for voltage transients in industrial SMPS
R_DS(on)	0.166Ω @ V_GS = 10V - delivers ≤12W conduction loss at 12A, critical for thermal management in enclosed enclosures
I_D (T_C = 25°C)	12A - maximum continuous drain current under heatsink-cooled conditions, defining PCB copper and heatsink sizing
E_AS	130mJ - enables unclamped inductive switching survival in motor phase-legs without external snubbers
t_r/t_f	45ns/36ns - reduces switching losses below 200kHz operation, suitable for high-frequency buck converters
Q_g	35nC - determines gate driver peak current requirement (≥1.5A for 25ns turn-on) and driver IC selection
V_SD	1.3V @ I_S = 7.2A - defines forward conduction loss during freewheeling in half-bridge configurations

Pinout & Package

IRL3215 uses the industry-standard TO-220AB package with isolated tab (drain-connected), offering low thermal resistance (R_θJC = 1.9°C/W) and mechanical compatibility with universal heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
1 - Gate	Control electrode	Receives logic-level gate drive; requires <1.5A peak current to charge 35nC total gate charge within 25ns
2 - Drain	High-side power terminal	Internally connected to metal tab; must be electrically isolated from heatsink unless system ground reference permits
3 - Source	Power return/reference node	Serves as local ground for gate drive circuitry; carries full load current and body diode reverse recovery charge

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 1.0–2.0V enables direct interface with 3.3V/5V MCUs without gate driver ICs
Fully avalanche-rated	130mJ single-pulse E_AS ensures reliability in inductive load switching without external protection
Low R_DS(on) × Q_g figure-of-merit	0.166Ω × 35nC = 5.81Ω·nC - balances conduction and switching losses for 100–200kHz operation
Fast body diode recovery	t_rr = 160–240ns with soft recovery minimizes voltage overshoot and EMI in freewheeling paths

Applications

Brushless DC Motor Drives

Use Scenario: 48V input, 12V/10A output synchronous buck converter in programmable logic controller (PLC) power modules.

IC Role / Device Role / Timing Role: High-side main switch operating at 150kHz with synchronous rectification using complementary low-side FET.

Use Value: 0.166Ω R_DS(on) limits conduction loss to 16.6W at full load, enabling compact heatsink design within 25mm × 25mm footprint.

Use Scenario: Phase-leg switch in 24V/300W BLDC motor controller for automated guided vehicle (AGV) traction.

IC Role / Device Role / Timing Role: Low-side switch in three-phase inverter bridge, commutated at ≤20kHz with PWM dead-time control.

Use Value: 130mJ avalanche rating absorbs inductive kickback during short-circuit events, eliminating need for external TVS clamps.

Equivalent & Alternatives

The following parts are listed as comparable options for similar power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP16NF15	150V, 16A, R_DS(on) = 0.18Ω @ 10V; higher ID but slightly higher on-resistance	Higher continuous current rating suits higher-power motor drives but requires larger gate drive current (Q_g = 45nC)	Select when >12A continuous current is required and gate drive capability supports 45nC charge
IRFZ44N	55V, 49A, R_DS(on) = 0.028Ω @ 10V; lower voltage rating, much lower on-resistance	Only suitable for ≤48V systems; unsuitable for 120V bus applications due to V_DS derating	Choose only for low-voltage, high-current designs where 55V breakdown is sufficient and thermal budget allows lower R_DS(on)

Compared with STP16NF15 and IRFZ44N, the IRL3215 uniquely balances 150V rating, logic-level drive, and 0.166Ω on-resistance - making it optimal for 48–120V industrial power stages where voltage margin, gate drive simplicity, and thermal efficiency are jointly constrained.

FAQ

Is the IRL3215 suitable for 3.3V microcontroller gate drive?

Yes. With a gate threshold voltage range of 1.0–2.0V and guaranteed R_DS(on) at V_GS = 4.0V (0.208Ω), the IRL3215 fully turns on using standard 3.3V GPIO outputs. However, for lowest R_DS(on) and fastest switching, 5V or 10V gate drive is recommended to minimize conduction loss and switching time.

What is the maximum safe operating temperature for continuous operation?

The IRL3215 has a maximum junction temperature of +175°C and operates continuously up to +150°C case temperature (I_D = 8.5A). For reliable long-term operation, maintain T_C ≤ 100°C using a heatsink with R_θCA ≤ 5.3°C/W, calculated from P_D = 80W × (1 − 100/175) ≈ 34W at T_C = 100°C.

Does the IRL3215 require a gate resistor for stability?

Yes. A series gate resistor (typically 10–22Ω) is required to dampen parasitic oscillation caused by gate-drain capacitance (C_rss = 70pF) and PCB inductance. Without it, ringing can exceed V_GS absolute maximum (±16V), risking gate oxide damage during fast switching transitions.

Can the IRL3215 replace the IRF3205 in existing designs?

No. Although both are TO-220 N-channel MOSFETs, the IRF3205 has V_DS = 55V and R_DS(on) = 0.08Ω - incompatible with 150V applications. Substituting IRL3215 into a 55V design risks excessive conduction loss (0.166Ω vs. 0.08Ω) and reduced efficiency; voltage rating mismatch also invalidates safety margins.
