Product details

Overview

AOT380A60CL from Alpha & Omega Semiconductor is a 600V, 44A N-channel enhancement-mode MOSFET in TO-220 package, featuring 0.38Ω max R_DS(ON), 18nC typical gate charge, and 100% UIS-tested ruggedness. It serves as a primary switching device in high-efficiency AC-DC power supplies including PFC, flyback, and LLC topologies for server, TV, and lighting applications.

For engineers reviewing the AOT380A60CL datasheet, pinout, applications, or equivalent options, key selection criteria include its 700V V_DS rating at T_J,max, 251ns body diode reverse recovery time, 2.6mJ E_oss at 400V, thermal resistance R_θJC of 0.95°C/W, and SMPS-specific optimization for EMI reduction.

Technical Context

This MOSFET employs proprietary aMOS5™ technology to achieve low conduction loss and fast switching with controlled dv/dt. Its enhanced body diode delivers 19A peak reverse recovery current (I_RM) and 3.1mC Q_rr under 400V/100A/μs conditions, enabling robust operation in hard-switched converters.

The device supports gate drive with ±20V V_GS rating and exhibits 9.3S forward transconductance (g_FS) at 5.5A. Its SOA is defined up to 150°C junction temperature, with R_DS(ON) drift coefficient of 0.44V/°C and normalized BVDSS variation across temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP60N60DM6	R_DS(ON) = 0.036Ω (lower), Q_g = 45nC (higher), TO-247 package	Higher conduction efficiency but larger footprint and higher gate drive loss	Preferred where board space allows and gate drive capability supports 45nC charge
IPP60R190C7	R_DS(ON) = 0.19Ω (lower), E_oss = 1.8mJ (lower), TO-220FP package	Superior switching efficiency but rated only for 600V (not 700V at T_J,max)	Selected when strict 600V operation suffices and lowest E_oss is prioritized over transient margin

Compared with STP60N60DM6 and IPP60R190C7, the AOT380A60CL offers balanced trade-offs: TO-220 compatibility, 700V V_DS headroom, and optimized R_DS(ON)/Q_g for mid-power SMPS where layout density and thermal interface simplicity are critical.

FAQ

What is the maximum continuous drain current rating for AOT380A60CL at 100°C case temperature?

The AOT380A60CL supports 7.2A continuous drain current (I_D) at T_C = 100°C, as specified in the Absolute Maximum Ratings table. This rating is thermally limited by junction temperature (T_J ≤ 150°C) and assumes proper heatsinking with R_θJC = 0.95°C/W. At T_C = 25°C, the rating increases to 11A. The AOT380A60CL datasheet confirms this derating curve in Figure 10.

Does AOT380A60CL support logic-level gate drive?

No, the AOT380A60CL is not a logic-level MOSFET. Its gate threshold voltage (V_GS(th)) ranges from 2.6V to 3.8V, but full enhancement requires V_GS = 10V per the R_DS(ON) specification. The device is characterized at V_GS = 10V for 0.38Ω max on-resistance and switching parameters. Driving below 8V risks incomplete turn-on and excessive conduction loss. The AOT380A60CL requires standard 10V gate drive.

Is AOT380A60CL suitable for use in avalanche-rated circuits?

Yes, the AOT380A60CL is 100% tested for unclamped inductive switching (UIS) with single-pulse avalanche energy (E_AS) of 1.0mJ at T_J = 25°C, I_L = 2A, L = 105mH, and R_GS = 25Ω. Repetitive avalanche is not rated, and operation beyond single-pulse conditions requires careful SOA validation. The AOT380A60CL's UIS test data appears in the Product Summary section of the datasheet.

What is the thermal resistance from junction to case (R_θJC) for AOT380A60CL?

The AOT380A60CL has a junction-to-case thermal resistance (R_θJC) of 0.95°C/W, measured with the device mounted to a large heatsink. This value is used to calculate junction temperature rise under power dissipation: T_J = T_C + P_D × 0.95. The AOT380A60CL's R_θJC is confirmed in the Thermal Characteristics table on page 1 of the datasheet.

How does the body diode performance of AOT380A60CL compare to standard superjunction MOSFETs?

The AOT380A60CL features an enhanced body diode with 251ns reverse recovery time (t_rr) and 3.1mC reverse recovery charge (Q_rr) at I_F = 5.5A, dI/dt = 100A/μs, and V_DS = 400V. This represents ~22% faster t_rr and ~35% lower Q_rr than typical 600V superjunction MOSFETs at comparable R_DS(ON). The AOT380A60CL's improved diode ruggedness reduces switching loss and EMI in flyback and LLC freewheeling paths.
