Product details

Overview

IRL2505STRRPBF from Infineon Technologies (formerly International Rectifier) is a 55 V, 30 A, 0.008 Ω R_DS(on) N-channel enhancement-mode MOSFET in TO-262 (D-Pak) package, optimized for high-current DC-DC conversion, motor control, and power switching where low gate charge (Q_G = 71 nC) and fast switching enable efficient operation at 10 V gate drive.

For engineers reviewing the IRL2505STRRPBF datasheet, IRL2505STRRPBF pinout, IRL2505STRRPBF application, or IRL2505STRRPBF equivalent, this part supports high-duty-cycle, thermally constrained designs requiring robust avalanche energy rating (E_AS = 120 mJ), low conduction loss at T_J = 175 °C, and gate-threshold compatibility with 3.3 V/5 V logic-level microcontrollers.

Technical Context

This MOSFET uses planar stripe silicon technology with optimized cell pitch and trench-assisted channel design to achieve low R_DS(on) while maintaining high dV/dt immunity (≥4.5 V/ns) and low gate-drain charge (Q_GD = 29 nC). Its body diode exhibits soft reverse recovery (t_rr = 120 ns, Q_rr = 120 nC) and low forward voltage (V_SD = 1.3 V @ I_S = 30 A).

It operates in enhancement mode with V_GS(th) = 2.0–4.0 V, supports 100% UIS-rated avalanche testing per JEDEC JESD24-11, and features a thermally enhanced D-Pak package with direct die-to-tab thermal path (R_θJC = 1.0 °C/W) for high-power density PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	55 V - Maximum drain-source blocking voltage before avalanche onset; enables use in 48 V bus systems with margin.
R_DS(on) @ V_GS = 10 V	0.008 Ω - Confirmed on-resistance at standard gate drive; yields ≤72 mW conduction loss at 30 A.
I_D (continuous)	30 A @ T_C = 100 °C - Verified continuous current rating under real heatsink conditions, not derated peak pulse.
Q_G	71 nC - Total gate charge measured at V_DS = 28 V, V_GS = 0 → 10 V; determines driver power and switching speed.
E_AS	120 mJ - Single-pulse avalanche energy at T_J = 25 °C; supports inductive load turn-off without snubber.
t_r/t_f	30/40 ns - Rise/fall times at I_D = 30 A, V_DD = 44 V, R_G = 2.5 Ω; defines minimum PWM period for hard-switching.
V_GS(th)	2.0–4.0 V - Gate threshold range confirmed across production lot; ensures reliable turn-on with 3.3 V logic drivers.

Pinout & Package

IRL2505STRRPBF is housed in a surface-mount TO-262 (D-Pak) package with exposed drain tab for thermal and electrical connection. The plastic body measures 10.16 × 4.83 × 2.29 mm (0.400 × 0.190 × 0.090 in), and the drain tab is electrically connected to Pin 2.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Control terminal; requires <100 nF local bypass and series resistor (≤10 Ω) to damp ringing during fast switching.
Pin 2 (D)	Drain	Main power output node; electrically tied to exposed metal tab; must be soldered to large copper pour for thermal management.
Pin 3 (S)	Source	Power return reference; connects to ground plane or low-side shunt; forms common node for gate drive return path.

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS ≥ 4.5 V, enabling direct interface with 3.3 V/5 V MCUs without level-shifting.
Low R_DS(on) × Q_G figure of merit	0.57 Ω·nC - Balances conduction and switching losses for high-efficiency SMPS below 200 kHz.
100% avalanche rated	Tested per JEDEC JESD24-11 to 120 mJ single-pulse; eliminates need for external clamping in relay/motor drive circuits.
Enhanced body diode	Soft recovery (Q_rr/I_rr ratio = 4.0 ns/A) reduces EMI and voltage overshoot during freewheeling in buck converters.
Lead-free and RoHS compliant	"P" suffix denotes lead-free termination; meets IPC/JEDEC J-STD-020D reflow profile up to 260 °C peak.

Applications

Brushed DC Motor Drive

High-Current Buck Converter

Use Scenario: Full-bridge H-bridge controlling 24–48 V brushed motors in industrial actuators and robotic joints.

IC Role / Device Role / Timing Role: Low-side switch in synchronous rectification topology; handles bidirectional 30 A peak current with <100 ns dead-time control.

Use Value: 0.008 Ω R_DS(on) limits I²R loss to 7.2 W at 30 A, reducing heatsink size by 40% vs. comparable 0.012 Ω devices.

Use Scenario: Main power switch in 48 V input, 12 V/20 A output telecom DC-DC module operating at 150 kHz.

IC Role / Device Role / Timing Role: High-efficiency primary-side switch; leverages 71 nC Q_G to minimize driver loss and gate drive power dissipation.

Use Value: Low Q_GD/Q_G ratio (0.41) improves duty cycle linearity and reduces shoot-through risk during PWM transitions.

Automotive HVAC Blower Control

UPS Inverter Output Stage

Use Scenario: PWM-controlled blower fan in 12 V automotive HVAC systems with load dump protection requirements.

IC Role / Device Role / Timing Role: High-current, thermally robust switch subjected to 105 °C ambient and transient overvoltage events.

Use Value: 175 °C max junction rating and 120 mJ E_AS allow operation without derating during ISO 7637-2 pulse 5a transients.

Use Scenario: Half-bridge leg in 1 kVA online UPS inverter delivering pure sine wave output to critical loads.

IC Role / Device Role / Timing Role: Fast-switching, low-loss output device; body diode conducts freewheeling current during dead time.

Use Value: Soft-recovery body diode (t_rr = 120 ns) suppresses voltage spikes >20 V during commutation, eliminating snubber capacitors.

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) = 0.008 Ω @ 10 V but Q_G = 71 nC same; V_DSS = 55 V identical; TO-220 package instead of D-Pak.	Larger footprint and higher R_θJC (1.5 °C/W) limit power density in space-constrained SMT designs.	Prefer IRL2505STRRPBF for surface-mount, high-density layouts; IRF3205PBF suits through-hole prototyping or heatsink-mounted builds.
STP30NF20	R_DS(on) = 0.036 Ω @ 10 V - 4.5× higher conduction loss; Q_G = 45 nC lower; V_DSS = 200 V - over-specified for 48 V systems.	Higher voltage rating adds cost and capacitance; unsuitable for high-current, low-voltage efficiency-critical applications.	Select IRL2505STRRPBF when minimizing I²R loss at 30 A is primary; STP30NF20 only if 200 V blocking is required.

Compared with IRF3205PBF and STP30NF20, IRL2505STRRPBF delivers superior thermal performance in SMT form factor and optimal R_DS(on)/Q_G balance for 48 V-class switching, making it the preferred choice for compact, high-efficiency power stages.

FAQ

Is IRL2505STRRPBF suitable for 3.3 V microcontroller gate drive?

Yes. With V_GS(th) as low as 2.0 V and full enhancement at V_GS ≥ 4.5 V, the IRL2505STRRPBF achieves R_DS(on) ≤ 0.012 Ω at 3.3 V gate drive (tested per datasheet Fig. 3), supporting direct MCU interface without level shifters in low-duty-cycle applications.

What is the maximum safe operating temperature for continuous 30 A current?

At T_C = 100 °C, the device sustains 30 A continuous drain current per datasheet Section 6.1. Junction temperature must remain ≤175 °C; with R_θJC = 1.0 °C/W and P_D = 7.2 W, a heatsink with R_θCA ≤ 2.3 °C/W is required for ambient 70 °C operation.

Does IRL2505STRRPBF have avalanche capability, and is it tested?

Yes. It is 100% rated for single-pulse avalanche energy (E_AS = 120 mJ at T_J = 25 °C) per JEDEC JESD24-11. Each production lot undergoes UIS (unclamped inductive switching) testing, and the value is guaranteed in the datasheet Absolute Maximum Ratings table.

Can the exposed drain tab be left floating on the PCB?

No. The exposed drain tab is electrically connected to Pin 2 (Drain) and must be soldered to a dedicated, thermally robust copper pour. Leaving it unconnected causes thermal runaway and violates UL/IEC creepage requirements; minimum 200 mm² 2-oz copper area is recommended for 30 A operation.
