Product details

Overview

IRL3202PBF from Infineon Technologies (formerly International Rectifier) is a 55 V, 110 A, 4.0 mΩ N-channel HEXFET Power MOSFET in TO-220AB package, optimized for high-efficiency DC-DC conversion and motor drive applications with logic-level gate drive compatibility down to 4.5 V.

For engineers reviewing the IRL3202PBF datasheet, IRL3202PBF pinout, IRL3202PBF application, or IRL3202PBF equivalent, key selection criteria include R_DS(on) at 4.5 V V_GS, single-pulse avalanche energy rating, thermal resistance (R_θJC = 1.0 °C/W), and TO-220AB lead assignment compliance with JEDEC outline.

Technical Context

This MOSFET employs trench-gate silicon process technology to achieve low on-resistance while maintaining fast switching speed and robust avalanche capability. Its gate threshold voltage (V_GS(th)) ranges from 1.0 V to 2.0 V, enabling reliable turn-on with standard logic-level drivers.

The device supports continuous drain current up to 110 A at T_C = 25 °C and delivers 29 A at V_GS = 4.5 V, with normalized R_DS(on) stable across junction temperatures from −55 °C to 175 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V - Maximum blocking voltage before avalanche breakdown; suitable for 48 V bus systems with margin.
R_DS(on) @ V_GS = 4.5 V	4.0 mΩ - Enables <1 W conduction loss at 50 A, critical for high-current synchronous rectification.
I_D (continuous)	110 A @ T_C = 25 °C - Supports high-power motor control without forced air cooling when mounted on adequate heatsink.
E_AS	130 mJ - Single-pulse avalanche energy rating ensures reliability during inductive load switching transients.
R_θJC	1.0 °C/W - Thermal resistance from junction to case enables precise thermal design for TO-220AB mounting.
Q_g	71 nC @ V_GS = 15 V - Gate charge value determines driver strength requirement for 100 kHz+ switching.
C_iss	2200 pF @ V_DS = 25 V - Input capacitance impacts gate drive loop stability and EMI filtering needs.

Pinout & Package

IRL3202PBF is housed in a TO-220AB package with exposed drain tab for thermal and electrical connection. The package meets JEDEC MS-001AC outline standards and supports vertical mounting with insulating shoulder washers.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control terminal	Receives logic-level voltage (≥4.5 V) to fully enhance channel; requires low-impedance drive due to 71 nC Q_g.
2 (Drain)	High-side power output	Internally connected to metal tab; must be electrically isolated from heatsink unless system ground reference permits.
3 (Source)	Power return path	Serves as reference node for gate drive; layout must minimize inductance to prevent ringing during switching.
4 (Drain)	Secondary drain connection	Parallel drain path to Pin 2; improves current sharing and reduces package inductance in high-di/dt applications.

Key Features

Feature	Design Value
Logic-level gate drive	Guaranteed R_DS(on) ≤ 4.0 mΩ at V_GS = 4.5 V - eliminates need for gate driver ICs in microcontroller-based designs.
Enhanced avalanche ruggedness	130 mJ single-pulse rating - protects against inductive kickback in H-bridge motor drives without external snubbers.
Low gate charge	71 nC total gate charge - enables efficient 100–500 kHz operation with standard MOSFET drivers like IR2104.
TO-220AB dual-drain configuration	Pins 2 and 4 both tied to drain - reduces source inductance and improves current handling versus single-drain variants.
Lead-free and RoHS compliant	"PBF" suffix denotes Pb-free termination - satisfies IPC-J-STD-020 moisture sensitivity level 1 and industrial environmental requirements.

IC Role / Device Role / Timing Role: High-current, low-V_DS freewheeling switch synchronized to primary-side FET timing.

Use Value: Dual-drain TO-220AB layout minimizes source inductance, improving cross-conduction immunity and transient response.

Use Value: Logic-level V_GS(th) (1.0–2.0 V) ensures full enhancement using automotive microcontroller outputs without level-shifting.

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
IRF3205PBF	R_DS(on) = 8.0 mΩ @ 10 V V_GS; higher gate threshold (2.0–4.0 V); no guaranteed 4.5 V drive spec.	Requires 10 V gate drive for optimal R_DS(on); less suitable for 3.3 V logic interfaces.	Select only if system uses 12 V gate drive and thermal budget allows +1.5 W conduction loss at 50 A.
STP55NF06L	R_DS(on) = 10.5 mΩ @ 5 V V_GS; lower I_D rating (55 A); different pinout (G-D-S).	Limited to lower-current applications; not drop-in compatible due to pin assignment mismatch.	Consider for cost-sensitive 30 A designs where TO-220AB footprint is acceptable but dual-drain performance is noncritical.

Compared with IRF3205PBF and STP55NF06L, IRL3202PBF provides superior conduction efficiency at logic-level drive voltages and unique dual-drain thermal/power routing-making it preferred for high-current, space-constrained synchronous rectifiers and motor inverters.

FAQ

What is the maximum safe operating temperature for IRL3202PBF?

The absolute maximum junction temperature is 175 °C, but sustained operation above 150 °C degrades long-term reliability. With R_θJC = 1.0 °C/W and typical case temperature of 85 °C under 110 A conduction, junction temperature reaches ~195 °C-so derating to 60–80 A is recommended for continuous use without active cooling.

Does IRL3202PBF require a gate resistor for switching?

Yes-a series gate resistor (typically 5–22 Ω) is required to dampen gate-source ringing caused by parasitic inductance and prevent spurious turn-on. Without it, the 71 nC gate charge and low input capacitance can excite oscillations exceeding V_GS(max) = ±20 V, risking gate oxide damage during fast dV/dt transitions.

Can IRL3202PBF be used in parallel configurations?

Yes, but only with matched devices and symmetrical PCB layout. Its positive temperature coefficient of R_DS(on) promotes current sharing, yet gate drive imbalance or thermal gradient across packages can cause unequal current distribution. Use individual gate resistors and Kelvin source connections to ensure stability at >200 A aggregate current.

Is the TO-220AB package electrically insulated?

No-the metal tab (Pins 2 and 4) is internally connected to the drain and is not electrically isolated. When mounting to a heatsink, a mica or polymer insulator plus shoulder washer must be used unless the heatsink is referenced to drain potential. Failure to insulate risks short-circuiting the drain to system ground or adjacent components.
