Product details

Overview

IRL620 from Vishay Siliconix is a logic-level N-channel power MOSFET in TO-220AB 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 = 5 V. It supports fast switching, repetitive avalanche operation, and is optimized for DC-DC converters, motor control, and industrial power supplies.

For engineers reviewing the IRL620 datasheet, IRL620 pinout, IRL620 application, or IRL620 equivalent, key selection criteria include its logic-level gate drive (V_GS(th) = 1.0–2.0 V), low R_DS(on) at 4–5 V, avalanche ruggedness (E_AS = 125 mJ), and TO-220AB thermal performance (R_thJC = 2.5 °C/W).

Technical Context

The IRL620 uses third-generation planar vertical DMOS technology with optimized cell layout for reduced gate charge (Q_g = 16 nC) and fast switching (t_r = 31 ns, t_f = 17 ns). Its body diode exhibits t_rr = 180–270 ns and Q_rr = 1.1–1.7 μC under specified conditions.

Designed for hard-switched topologies, it features dynamic dV/dt immunity up to 5.0 V/ns and is rated for repetitive avalanche (I_AR = 5.2 A, E_AR = 5.0 mJ), enabling robust operation in inductive load circuits without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - supports input voltages up to 160 V DC in offline or high-voltage DC-DC designs
R_DS(on) @ V_GS = 5 V	0.80 Ω - enables <5 W conduction loss at 5.2 A, suitable for thermally constrained PCBs
Q_g	16 nC - allows efficient gate driving with standard logic-level drivers (e.g., TC4420)
I_D (continuous, T_C = 25 °C)	5.2 A - delivers >25 W output in TO-220AB with heatsink
E_AS	125 mJ - withstands unclamped inductive energy in relay/motor drive without failure
V_GS(th)	1.0–2.0 V - fully enhances with 3.3 V or 5 V microcontroller GPIO, eliminating level shifters
R_thJC	2.5 °C/W - enables direct mounting to heatsink for stable junction temperature below 150 °C

Pinout & Package

IRL620 is housed in TO-220AB package with isolated tab (drain-connected), standard 3-pin through-hole configuration, and 1.1 N·m mounting torque rating.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heat sink interface	Electrically connected to metal tab; must be electrically isolated from chassis unless circuit design requires common-drain topology
Gate	Control electrode for channel modulation	Logic-compatible input requiring ≤100 nA leakage; sensitive to ESD-requires gate resistor (≥10 Ω) and TVS protection in noisy environments
Source	Reference node for gate drive and current return	Serves as local ground reference for gate driver; internal source inductance (L_S = 7.5 nH) affects high-speed switching ringing

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced with 3.3 V or 5 V MCU outputs-eliminates need for gate driver ICs in low-power control stages
Repetitive avalanche rated	Guarantees 5.2 A/5.0 mJ cyclic avalanche capability-supports reliable operation in flyback snubberless or solenoid drive circuits
Dynamic dV/dt immunity	Rated for 5.0 V/ns-prevents false turn-on during high dv/dt transients in half-bridge or phase-shifted topologies
Low Q_gd/Q_g ratio	Q_gd = 9.6 nC of total Q_g = 16 nC (60%)-delivers Miller plateau control for predictable switching transitions and reduced shoot-through risk
RoHS-compliant Pb-free/halogen-free option	IRL620PbF-BE3 variant meets JEDEC J-STD-609 Class 1 moisture sensitivity and IPC/JEDEC J-STD-020D reflow profiles

Equivalent & Alternatives

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP2NK60Z	600 V V_DS, higher R_DS(on) = 4.5 Ω @ 10 V, not logic-level (V_GS(th) = 2–4 V), Zener-protected	Better suited for 400 V+ flyback primary switches; requires gate driver for 3.3 V logic	Select when higher voltage blocking is required and gate drive voltage ≥10 V is available
FQP30N06L	60 V V_DS, lower R_DS(on) = 0.035 Ω @ 10 V, logic-level (V_GS(th) = 1–2.5 V), higher I_D = 30 A	Optimized for 12–24 V systems (e.g., automotive, battery-powered); insufficient for 160 V bus	Prefer for low-voltage, high-current loads where V_DS < 50 V; not safe for IRL620's 200 V use cases

Compared with STP2NK60Z and FQP30N06L, the IRL620 uniquely balances 200 V rating, logic-level drive, and 0.80 Ω on-resistance-making it optimal for 48–160 V industrial power stages where gate drive simplicity and avalanche ruggedness are critical.

FAQ

What is the maximum continuous drain current for the IRL620 at 100 °C case temperature?

The IRL620 supports 3.3 A continuous drain current at T_C = 100 °C, per Absolute Maximum Ratings table. This derating reflects thermal limits of the TO-220AB package and ensures junction temperature remains ≤150 °C with appropriate heatsinking and ambient conditions.

Does the IRL620 require a gate resistor, and what value is recommended?

Yes, the IRL620 requires an external gate resistor to control switching speed and suppress oscillation. A 10–25 Ω resistor is recommended-lower values increase dI/dt and risk ringing; higher values slow switching and raise losses. The datasheet specifies R_g = 25 Ω for avalanche testing and switching characterization.

Is the IRL620PbF-BE3 variant RoHS-compliant and halogen-free?

Yes, the IRL620PbF-BE3 is both lead (Pb)-free and halogen-free, meeting JEDEC J-STD-609 Class 1 and IPC/JEDEC J-STD-020D standards. It is explicitly designated in the Ordering Information table as "Lead (Pb)-free and halogen-free" and carries Vishay's material compliance certification per doc# 99912.

Can the IRL620 be used in parallel configurations, and what design considerations apply?

Yes, the IRL620 is designed for ease of paralleling due to positive R_DS(on) temperature coefficient and matched threshold voltage. Key considerations include symmetrical PCB layout, individual gate resistors (≤5 Ω mismatch), and Kelvin-source connections to minimize current imbalance caused by L_S = 7.5 nH parasitic inductance.

What is the body diode reverse recovery charge (Q_rr) of the IRL620, and how does it affect hard-switched operation?

The IRL620 body diode Q_rr is 1.1–1.7 μC at T_J = 25 °C, I_F = 5.2 A, and dI/dt = 100 A/μs. This value directly impacts turn-on loss in synchronous rectification or freewheeling paths-higher Q_rr increases voltage overshoot and EMI; designers should account for it in snubber sizing and dead-time optimization.
