Vishay Siliconix IRL530PBF

Overview

IRL530PBF from Vishay Siliconix is a logic-level N-channel Power MOSFET in TO-220AB package, rated for 100 V V_DS, 15 A continuous drain current at T_C = 25 °C, and 0.16 Ω R_DS(on) at V_GS = 5 V. It supports fast switching, repetitive avalanche operation up to 15 A, and operates reliably from –55 °C to +175 °C - commonly used in DC-DC converters, motor control H-bridges, and industrial power supplies.

For engineers reviewing the IRL530PBF datasheet, IRL530PBF pinout, IRL530PBF application, or IRL530PBF equivalent, key selection considerations include its logic-level gate drive compatibility with 4–5 V microcontrollers, low R_DS(on) enabling high-efficiency 12–24 V load switching, robust avalanche energy rating (290 mJ single-pulse), and TO-220AB thermal performance (R_thJC = 1.7 °C/W).

Technical Context

The IRL530PBF employs a third-generation trench-gate silicon process optimized for low gate charge (Q_g = 28 nC) and fast switching (t_r = 100 ns, t_f = 48 ns), enabling efficient operation in hard-switched SMPS topologies. Its body diode exhibits t_rr = 150–200 ns and Q_rr = 0.93–1.4 μC, supporting moderate-frequency synchronous rectification or freewheeling roles.

Designed for logic-level drive, it delivers full enhancement at V_GS = 4 V (R_DS(on) ≤ 0.22 Ω) and maintains stable threshold voltage (V_GS(th) = 1.0–2.0 V) across temperature. The device integrates a ruggedized structure qualified for repetitive avalanche (I_AR = 15 A, E_AR = 8.8 mJ) and dV/dt immunity (5.5 V/ns), suitable for inductive load switching without external snubbers.

Key Specifications

Pinout & Package

IRL530PBF uses the industry-standard TO-220AB package (3-pin, vertical mounting, isolated tab). The drain is internally connected to the metal tab for direct heatsink attachment and thermal path optimization.

FAQ

What is the maximum continuous drain current for IRL530PBF at 100 °C case temperature?

The IRL530PBF 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 TO-220AB package (R_thJC = 1.7 °C/W); actual usable current depends on heatsink performance and ambient conditions. Designers should verify junction temperature using P_tot = I_D² × R_DS(on) + switching losses and T_J = T_C + P_tot × R_thJC. The IRL530PBF remains within safe operating area up to 175 °C junction temperature.

Does IRL530PBF support logic-level gate drive from a 3.3 V microcontroller?

The IRL530PBF is explicitly characterized for logic-level operation, with R_DS(on) guaranteed ≤ 0.22 Ω at V_GS = 4.0 V and ID = 7.5 A. While 3.3 V is below the 4 V test condition, typical V_GS(th) (1.0–2.0 V) and transfer characteristics show strong enhancement starting at ~3 V. In practice, the IRL530PBF delivers usable conduction (R_DS(on) ≈ 0.3–0.4 Ω) at 3.3 V, but full 15 A capability requires ≥4 V drive. For 3.3 V systems, confirm load current and thermal margin in final design.

Is the metal tab of IRL530PBF electrically connected to any pin?

Yes - the metal tab of the IRL530PBF in TO-220AB package is internally connected to the Drain (D) terminal. This provides a low-inductance, low-thermal-resistance path to the heatsink but requires electrical isolation (e.g., mica washer + shoulder washer) if the heatsink is grounded or referenced to a different potential than the drain circuit. Failure to insulate may cause short circuits or ground loops. The IRL530PBF pinout confirms Drain as pin 2 (center lead) and tab connection in the Package Information section.

What is the body diode reverse recovery time (t_rr) of IRL530PBF, and how does it affect switching performance?

The IRL530PBF body diode exhibits t_rr = 150–200 ns at T_J = 25 °C, I_F = 15 A, and dI/dt = 100 A/μs. This relatively fast recovery minimizes voltage overshoot and cross-conduction risk during hard-commutation in half-bridge or synchronous rectifier configurations. However, designers must account for Q_rr = 0.93–1.4 μC in loss calculations and ensure adequate dead time - especially when paralleling devices or operating above 50 kHz. The IRL530PBF's t_rr is typical for logic-level MOSFETs of this voltage class.

Can IRL530PBF replace IRL530 in an existing design without layout changes?

Yes - the IRL530PBF is the RoHS-compliant, lead-free version of the IRL530, sharing identical TO-220AB package dimensions, pinout, and electrical specifications. Both parts have the same V_DS, R_DS(on), Q_g, thermal resistance, and avalanche ratings. The only difference is termination material (Pb-free vs. SnPb), which affects soldering profile (peak temperature 300 °C for 10 s). No PCB or schematic changes are required when substituting IRL530PBF for IRL530, provided the assembly process accommodates lead-free reflow.
