Product details

Overview

IRL510S from Vishay Siliconix is a logic-level N-channel power MOSFET in D2PAK (TO-263) package, rated for 100 V V_DS, 5.6 A continuous drain current at T_C = 25 °C, 0.54 Ω R_DS(on) at V_GS = 5 V, and 175 °C maximum junction temperature - designed for high-current DC-DC converters and motor drive half-bridges.

For engineers reviewing the IRL510S datasheet, IRL510S pinout, IRL510S application, or IRL510S equivalent, this part supports logic-level gate drive compatibility with 3.3 V/5 V microcontrollers, offers repetitive avalanche rating up to 4.3 mJ, and delivers low gate charge (6.1 nC) for efficient high-frequency switching in industrial power supplies and battery-powered systems.

Technical Context

The IRL510S uses a third-generation silicon process optimized for fast switching and ruggedized operation, featuring dynamic dv/dt immunity (5.5 V/ns) and integrated body diode with 110–130 ns reverse recovery time. Its gate threshold voltage (1.0–2.0 V) ensures reliable turn-on with standard logic outputs.

Thermal design is supported by low R_thJC = 3.5 °C/W and PCB-mount R_thJA = 40 °C/W, enabling 3.7 W dissipation on a 1" FR-4 board. The device is qualified for operation from –55 °C to +175 °C and rated for unclamped inductive switching with I_AS = 5.6 A and E_AS = 100 mJ.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports input rails up to 80 V DC with margin for transients in industrial power stages
R_DS(on) @ V_GS = 5 V	0.54 Ω - enables ≤10 W conduction loss at 4.3 A RMS in 12 V motor control H-bridge legs
Q_g	6.1 nC - allows <50 ns total switching time with 12 Ω gate resistor, reducing switching losses below 200 kHz
I_D (continuous, T_C = 25 °C)	5.6 A - sustains full-load current in compact surface-mount power modules without forced air
T_J max	+175 °C - permits operation in sealed enclosures or high-ambient environments like automotive under-hood or industrial PLCs
E_AS	100 mJ - withstands single-pulse inductive energy from solenoid or relay coil de-energization without failure
dv/dt rating	5.5 V/ns - suppresses false turn-on in noisy high-di/dt motor drive or SMPS layouts

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed drain tab for thermal and electrical connection; 3-pin configuration (G, D, S), lead (Pb)-free and halogen-free per Vishay specification.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control terminal	Accepts logic-level voltage (≥2.0 V) to fully enhance channel; requires <6.1 nC charge for full transition
D (Drain)	High-side power output	Connected to exposed metal tab - must be electrically isolated from heatsink unless referenced to system ground
S (Source)	Power return / reference node	Serves as local ground reference for gate drive; internal source inductance (7.5 nH) affects high-speed commutation ringing

Key Features

Feature	Design Value
Logic-level gate drive	Turns on fully at V_GS = 4 V - compatible with 3.3 V MCU GPIO without level-shifting circuitry
Repetitive avalanche rated	Withstands 4.3 mJ per pulse indefinitely - eliminates need for external snubbers in inductive load switching
Dynamic dv/dt immunity	5.5 V/ns threshold prevents spurious turn-on during fast voltage transients in half-bridge configurations
175 °C operating temperature	Enables use in thermally constrained spaces such as enclosed power tools or sealed LED drivers
Low Q_gd/Q_g ratio	3.3/6.1 ≈ 54% - improves Miller immunity and reduces risk of shoot-through in synchronous rectifiers

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
STP55NF06L	60 V V_DS, 55 A I_D, 0.014 Ω R_DS(on) - higher current, lower voltage rating	Not suitable for 80–100 V bus applications; better for 12–24 V high-current inverters	Select only if system V_DD ≤ 48 V and R_DS(on) < 0.02 Ω is required; requires PCB redesign due to TO-220 package
IRF540N	100 V V_DS, 33 A I_D, 0.044 Ω R_DS(on), V_GS(th) = 2–4 V - higher gate threshold, not logic-level	Requires ≥5 V gate drive; unsuitable for direct 3.3 V MCU interface without buffer	Choose when higher current and lower R_DS(on) justify added gate drive complexity and TO-220 thermal management

Compared with STP55NF06L and IRF540N, the IRL510S uniquely balances 100 V rating, true logic-level operation, and D2PAK thermal performance - making it optimal for space-constrained, medium-power industrial controls where gate drive simplicity and transient robustness are critical.

FAQ

What is the maximum continuous drain current for the IRL510S at 100 °C case temperature?

The IRL510S supports 4.0 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package under sustained high-temperature operation - designers must ensure adequate copper area and airflow to maintain case temperature within this limit for reliable IRL510S performance.

Does the IRL510S have an integrated body diode, and what are its key parameters?

Yes, the IRL510S includes an integral body diode rated for 5.6 A continuous forward current and 18 A pulsed current. Its V_SD is 2.5 V at I_S = 5.6 A and T_J = 25 °C, with t_rr = 110–130 ns and Q_rr = 0.50–0.65 μC - critical for synchronous rectification and freewheeling in buck or half-bridge topologies using the IRL510S.

Is the IRL510S RoHS-compliant, and what does "Pb-free and halogen-free" mean for this part?

The IRL510S variant IRL510STRLPbF is lead (Pb)-free but not halogen-free; the SiHL510STRL-GE3 variant is both Pb-free and halogen-free. "Pb-free" means termination finish contains no lead per EU RoHS Directive; "halogen-free" indicates bromine and chlorine content <900 ppm each - both versions meet Vishay's material categorization per doc# 99912, and the IRL510S complies with standard RoHS requirements for most industrial applications.

Can the IRL510S be used in avalanche mode, and what are the safe operating limits?

Yes, the IRL510S is repetitively avalanche-rated with E_AR = 4.3 mJ per pulse and I_AR = 5.6 A. Safe operation requires pulse width limited by junction temperature (see Fig. 11), V_DD ≤ V_DS, and T_J ≤ 175 °C. For unclamped inductive switching, the IRL510S withstands E_AS = 100 mJ single-pulse - verified per test conditions in Fig. 12 with L = 4.8 mH and R_g = 25 Ω.

What is the gate charge profile of the IRL510S, and how does it affect switching behavior?

The IRL510S has total gate charge Q_g = 6.1 nC, with Q_gs = 2.6 nC and Q_gd = 3.3 nC at V_GS = 5 V. This distribution indicates strong Miller effect sensitivity - Q_gd dominates the Miller plateau region, so gate resistor selection (e.g., 12 Ω) directly controls dV/dt during switching and impacts shoot-through risk in bridge circuits using the IRL510S.
