Product details

Overview

IRL530STRL from Vishay Siliconix is a logic-level N-channel power MOSFET in D2PAK (TO-263) package, rated for 100 V V_DS, 15 A continuous drain current at T_C = 25 °C, and R_DS(on) = 0.16 Ω at V_GS = 5 V. It supports repetitive avalanche operation, features dynamic dV/dt rating up to 5.5 V/ns, and operates up to 175 °C - ideal for high-current DC-DC converter primary-side switches and motor drive half-bridges.

For engineers reviewing the IRL530STRL datasheet, IRL530STRL pinout, IRL530STRL application, or IRL530STRL equivalent, key selection criteria include its logic-level gate drive compatibility with 4–5 V microcontrollers, low R_DS(on) enabling high-efficiency switching at moderate currents, robust avalanche energy rating (E_AS = 290 mJ), and surface-mount D2PAK thermal performance (R_thJC = 1.7 °C/W).

Technical Context

This device belongs to Vishay's third-generation power MOSFET family optimized for fast switching and ruggedized design. Its gate threshold voltage (V_GS(th) = 1.0–2.0 V) ensures reliable turn-on with standard logic-level drivers, while the low input capacitance (C_iss = 930 pF) and gate charge (Q_g = 28 nC) support efficient high-frequency PWM control.

The integrated body diode exhibits t_rr = 150–200 ns and Q_rr = 0.93–1.4 μC, making it suitable for synchronous rectification and freewheeling in inductive loads. Thermal design is enabled by its D2PAK package's low junction-to-case resistance and PCB-mount power dissipation of 3.7 W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports 48 V industrial bus and 24 V automotive systems with margin
R_DS(on) @ V_GS = 5 V	0.16 Ω - enables ≤2.25 W conduction loss at 12 A DC, reducing heatsink requirements
I_D (continuous, T_C = 25 °C)	15 A - sufficient for 200–300 W load switching in compact SMT designs
Q_g	28 nC - determines gate driver current demand (~1.4 A peak for 20 ns rise time)
E_AS	290 mJ - withstands unclamped inductive energy in motor commutation without failure
T_J max	175 °C - allows operation in sealed enclosures or high-ambient environments
dV/dt rating	5.5 V/ns - suppresses false turn-on in noisy high-dI/dt applications like H-bridge drives

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed drain tab for thermal conduction and mechanical anchoring. Three terminals: Gate (G), Drain (D), Source (S). Drain tab is electrically connected to the drain terminal and must be soldered to a large copper pour for optimal thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate control input	Logic-level compatible; requires ≤2.0 V V_GS(th) for turn-on; driven directly by MCU GPIO or dedicated gate driver
D	Drain (high-side switch node)	Connected to exposed metal tab; carries full load current and must be thermally coupled to PCB ground plane or heatsink
S	Source (return path)	Reference node for gate drive; forms low-impedance return path for load current and body diode conduction

Key Features

Feature	Design Value
Logic-level gate drive	Guaranteed turn-on at V_GS = 4 V, enabling direct interface with 3.3 V/5 V microcontrollers without level-shifting
Repetitive avalanche rated	Rated for I_AR = 15 A and E_AR = 8.8 mJ, allowing safe operation under transient overloads in motor control
Dynamic dV/dt immunity	5.5 V/ns rating prevents spurious turn-on during fast voltage transients in bridge configurations
High-temperature operation	175 °C maximum junction temperature supports use in sealed industrial enclosures and engine-bay proximity
Low R_DS(on) at low V_GS	0.22 Ω at V_GS = 4 V ensures minimal conduction loss even with marginal gate drive voltage

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
IRF530NPBF	Higher V_GS(th) (2–4 V), higher R_DS(on) (0.19 Ω @ 5 V), not logic-level rated	Requires ≥10 V gate drive; unsuitable for 3.3 V MCU direct drive	Select IRL530STRL when gate drive voltage is limited to ≤5 V and low on-resistance is critical
STP16NF10	Same V_DS (100 V), slightly higher R_DS(on) (0.18 Ω @ 5 V), lower Q_g (18 nC)	Better switching speed but reduced avalanche ruggedness (E_AS = 170 mJ vs. 290 mJ)	Prefer IRL530STRL in inductive load applications requiring high unclamped energy handling

Compared with IRF530NPBF and STP16NF10, the IRL530STRL delivers superior logic-level drivability, lower conduction loss, and highest single-pulse avalanche energy - making it the preferred choice for space-constrained, thermally demanding, and inductively loaded 100 V switching applications where gate voltage headroom is limited.

FAQ

What is the maximum continuous drain current for IRL530STRL at 100 °C case temperature?

The IRL530STRL supports 11 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the D2PAK package and must be validated against actual PCB layout and ambient conditions. Designers should reference the "Maximum Drain Current vs. Case Temperature" curve (Fig. 8) to confirm safe operating area for their specific thermal environment. The IRL530STRL maintains R_DS(on) stability up to 175 °C junction temperature.

Does IRL530STRL have a built-in body diode, and what are its key parameters?

Yes, the IRL530STRL integrates a parasitic body diode inherent to its vertical N-channel MOSFET structure. Key parameters include V_SD = 2.5 V at T_J = 25 °C and I_S = 15 A, reverse recovery time t_rr = 150–200 ns, and reverse recovery charge Q_rr = 0.93–1.4 μC. These values are measured under standardized conditions (IF = 15 A, dI/dt = 100 A/μs) and define its suitability for freewheeling and synchronous rectification. The IRL530STRL body diode is not optimized for ultrafast recovery but provides robust performance in typical motor and converter applications.

Is IRL530STRL RoHS-compliant and halogen-free?

Yes, the IRL530STRL is RoHS-compliant and halogen-free, as confirmed in the Vishay datasheet (S21-0932-Rev. D) and ordering information. It carries the "-GE3" suffix in lead-free/halogen-free variants (e.g., SiHL530STRR-GE3), and the IRL530STRL itself is manufactured to meet JEDEC J-STD-020 moisture sensitivity and RoHS Directive 2011/65/EU requirements. Material compliance documentation is accessible via Vishay's website using document number 91342.

What is the thermal resistance from junction to case (R_thJC) for IRL530STRL?

The maximum junction-to-case (drain) thermal resistance R_thJC for IRL530STRL is 1.7 °C/W, as stated in the Thermal Resistance Ratings table. This value applies when the device is mounted with proper solder coverage on a PCB and assumes the drain tab is the primary thermal path. Effective heatsinking requires a low-thermal-resistance interface (e.g., thermal pad or paste) between the exposed drain tab and the PCB copper pour or external heatsink. The IRL530STRL's D2PAK package enables this low R_thJC due to its large metal tab area and short internal thermal path.

Can IRL530STRL be used in avalanche mode, and what are its ratings?

Yes, the IRL530STRL is explicitly rated for repetitive avalanche operation per its datasheet. It supports repetitive avalanche current I_AR = 15 A and repetitive avalanche energy E_AR = 8.8 mJ, with single-pulse avalanche energy E_AS = 290 mJ. These ratings assume pulse width and duty cycle limitations defined in the datasheet notes (e.g., pulse width ≤ 300 μs, duty cycle ≤ 2 %). The IRL530STRL's ruggedized die design and specified test conditions (V_DD = 25 V, L = 1.9 mH, R_g = 25 Ω) validate its use in inductive switching applications such as motor drives without external protection.
