Product details

Overview

IRL620SPBF from Vishay Siliconix is a logic-level N-channel power MOSFET in D2PAK (TO-263) package, rated for 200 V V_DS, 5.2 A continuous drain current at T_C = 25 °C, and 0.80 Ω R_DS(on) at V_GS = 10 V. It supports fast switching, repetitive avalanche operation, and is optimized for high-current DC-DC converters and motor control circuits requiring low gate drive voltage.

For engineers reviewing the IRL620SPBF datasheet, IRL620SPBF pinout, IRL620SPBF application, or IRL620SPBF equivalent, key selection criteria include its 4 V logic-level gate threshold, 16 nC total gate charge, 2.5 °C/W junction-to-case thermal resistance, and D2PAK surface-mount footprint compatibility with high-power PCB layouts.

Technical Context

This MOSFET employs third-generation silicon technology to achieve ruggedized device design with enhanced dV/dt immunity and unclamped inductive switching capability. Its dynamic parameters-9.6 nC Q_gd, 31 ns rise time, and 180–270 ns body diode reverse recovery time-are specified under standardized test conditions (V_DD = 100 V, I_D = 5.2 A, R_g = 9.0 Ω).

The device integrates a monolithic p–n body diode with 1.8 V forward voltage at 5.2 A and is rated for 125 mJ single-pulse avalanche energy. Thermal performance is defined by R_thJC = 2.5 °C/W and R_thJA = 62 °C/W (mounted on FR-4), enabling stable operation up to 150 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	200 V - supports input stages in 100–150 V bus systems without derating
R_DS(on) @ V_GS = 4 V	1.0 Ω - enables direct drive from 3.3 V/5 V microcontrollers without level-shifting
Q_g (Total Gate Charge)	16 nC - determines gate driver power requirement and switching loss in hard-switched topologies
I_D Continuous @ T_C = 100 °C	3.3 A - defines usable current in thermally constrained heatsink-less designs
E_AS (Avalanche Energy)	125 mJ - allows safe operation during inductive load turn-off transients without external snubbers
R_thJC	2.5 °C/W - enables direct thermal coupling to copper pour or heatsink for >30 W dissipation

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection; 3-terminal configuration (G, D, S); standard JEDEC outline; recommended minimum pad layout per Vishay AN826.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Accepts logic-level voltage (1.0–2.0 V V_GS(th)) to fully enhance channel; requires <16 nC charge for full switching
D (Drain)	High-side power terminal	Connected to exposed copper thermal pad; carries full load current and dissipates heat directly to PCB copper or heatsink
S (Source)	Reference node / return path	Provides low-inductance source return; internal LS = 7.5 nH limits di/dt-induced shoot-through risk in half-bridge configurations

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4 V, eliminating need for gate driver ICs in 3.3 V/5 V control systems
Repetitive avalanche rated	Rated for 5.2 A I_AR and 5.0 mJ E_AR, enabling robustness in flyback and relay-driving applications
Dynamic dV/dt immunity	5.0 V/ns rated peak diode recovery dV/dt ensures reliable commutation in noisy inductive environments
Low Q_gd/Q_g ratio	9.6 nC / 16 nC = 60 % - improves Miller immunity and reduces risk of false turn-on in high-speed switching

Equivalent & Alternatives

FAQ

What is the maximum continuous drain current for IRL620SPBF at 100 °C case temperature?

The IRL620SPBF supports 3.3 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to reduced channel conductivity and increased R_DS(on) at elevated temperatures, and must be validated against actual PCB layout and ambient conditions in the final design.

Does IRL620SPBF have avalanche capability, and how is it rated?

Yes, IRL620SPBF is repetitively avalanche rated with 5.2 A I_AR and 5.0 mJ E_AR, and single-pulse rated for 125 mJ E_AS. These ratings are measured under defined test conditions (V_DD = 50 V, L = 6.9 mH, R_g = 25 Ω) and enable reliable operation in inductive switching without external clamping components when used within datasheet limits.

What is the gate-source threshold voltage range for IRL620SPBF?

The gate-source threshold voltage (V_GS(th)) for IRL620SPBF is specified from 1.0 V to 2.0 V at I_D = 250 μA and T_J = 25 °C. This low threshold enables full enhancement with 3.3 V or 5 V logic signals, making the IRL620SPBF suitable for direct microcontroller drive without level-shifting circuitry.

Can IRL620SPBF be used in surface-mount PCB designs without a heatsink?

IRL620SPBF can operate without an external heatsink in low-duty-cycle or low-power applications, provided the PCB provides adequate copper area (e.g., 1" square FR-4) and power dissipation remains ≤3.1 W. For continuous 5.2 A operation, thermal design must incorporate the 2.5 °C/W R_thJC path to a heatsink or large internal copper plane to maintain T_J ≤150 °C.

What is the body diode reverse recovery time for IRL620SPBF?

The body diode reverse recovery time (t_rr) for IRL620SPBF is 180–270 ns at T_J = 25 °C, I_F = 5.2 A, and dI/dt = 100 A/μs. This parameter impacts switching loss and EMI in freewheeling paths; designers should account for it in snubber design and layout to minimize voltage overshoot during diode commutation in the IRL620SPBF.
