Product details

Overview

AOT7N60 from Alpha & Omega Semiconductor is a 600 V, 7 A N-channel enhancement-mode MOSFET in TO-220 package, featuring 1.4 Ω R_DS(on) at V_GS = 10 V, 100% avalanche-rated, and optimized for offline AC-DC power supplies and DC-DC converters.

For engineers reviewing the AOT7N60 datasheet, pinout, applications, or equivalent options, key selection criteria include breakdown voltage rating, conduction loss at operating gate drive, unclamped inductive switching capability, thermal resistance (R_θJC = 1.5 °C/W), and TO-220 mechanical compatibility with standard heatsinks.

Technical Context

The AOT7N60 operates as a high-voltage power switch in flyback, forward, and resonant converter topologies. Its 600 V V_DSS supports universal input AC-DC designs, while its 1.4 Ω R_DS(on) minimizes conduction loss at 7 A continuous drain current.

Designed with planar stripe DMOS technology, it delivers robust UIS (unclamped inductive switching) performance up to 100 mJ at T_J = 25 °C and features a fast body diode with 120 ns reverse recovery time (t_rr) for improved efficiency in hard-switched applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - Withstands peak line voltages in 230 VAC mains-fed SMPS without breakdown
I_D (continuous)	7 A @ T_C = 25 °C - Supports medium-power adapters and auxiliary supplies
R_DS(on)	1.4 Ω max @ V_GS = 10 V - Enables low conduction loss in 12–24 W output designs
E_AS	100 mJ @ T_J = 25 °C - Ensures reliable operation under transient overloads and inductive kickback
t_rr	120 ns - Reduces switching loss and EMI in hard-switched converters
R_θJC	1.5 °C/W - Allows direct mounting to heatsink for thermal management in enclosed enclosures

Pinout & Package

TO-220 package with 3-pin through-hole configuration: Drain (tab), Source (pin 1), Gate (pin 2). The metal tab is electrically connected to the Drain terminal and serves as primary heat dissipation path.

Pin/Terminal	Circuit Role	Design Meaning
Tab (Drain)	Main high-side current path	Electrically tied to internal drain; requires isolation washer when mounted to grounded heatsink
Pin 1 (Source)	Reference node for gate drive and current return	Connects to power ground or source of synchronous rectifier; defines local reference for V_GS
Pin 2 (Gate)	Control terminal for channel conduction	Requires 10 V drive for full enhancement; gate charge Q_g = 22 nC enables moderate-speed switching

Key Features

Feature	Design Value
100% UIS tested	Guarantees ruggedness against inductive energy spikes without external snubbers
Fast body diode (t_rr = 120 ns)	Reduces reverse recovery loss and associated ringing in non-synchronous flyback designs

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
STP7NK60ZFP	R_DS(on) = 1.2 Ω (slightly lower), E_AS = 90 mJ, TO-220FP (shorter lead form)	Lower R_DS(on) improves light-load efficiency but reduced avalanche margin may require snubber redesign	Prefer for higher-efficiency, lower-stress designs where layout allows TO-220FP footprint
FQP7N60C	R_DS(on) = 1.3 Ω, t_rr = 200 ns, no UIS rating specified	Slower body diode increases switching loss in DCM flyback; lacks guaranteed avalanche testing	Acceptable for cost-sensitive, non-critical applications with conservative derating and added clamping

Compared with STP7NK60ZFP and FQP7N60C, the AOT7N60 offers balanced trade-offs: superior UIS ruggedness versus FQP7N60C and better thermal dissipation (R_θJC = 1.5 °C/W vs. 2.0 °C/W for ZFP) versus STP7NK60ZFP, making it optimal for industrial-grade reliability in compact heatsink layouts.

FAQ

What is the maximum gate-source voltage rating for AOT7N60?

The AOT7N60 has a maximum rated gate-source voltage (V_GS) of ±30 V. Exceeding this limit risks permanent gate oxide damage. For reliable operation, gate drive should be limited to 10–15 V for full enhancement, with transient spikes clamped using Zener diodes or gate resistors. The AOT7N60 datasheet specifies ±30 V as absolute maximum, and sustained operation above ±20 V is not recommended.

Does AOT7N60 support 230 VAC universal input applications?

Yes, the AOT7N60 supports 230 VAC universal input applications. Its 600 V V_DSS rating provides sufficient margin for the 385 V DC link voltage after bridge rectification and bulk capacitance, including line surges and ripple. Designers routinely use the AOT7N60 in DCM flyback converters delivering up to 24 W from 85–265 VAC inputs without additional voltage clamping.

Is the AOT7N60 pin-compatible with other TO-220 MOSFETs like IRF840?

No, the AOT7N60 is not pin-compatible with IRF840. While both use TO-220 packages, the AOT7N60 has Drain-tab / Source-pin1 / Gate-pin2 pinout, whereas IRF840 uses Drain-tab / Gate-pin1 / Source-pin2. Swapping them without board revision will cause immediate failure. Always verify pinout diagrams before substitution - the AOT7N60 pinout must be confirmed from its official datasheet.

What is the typical gate charge (Q_g) of AOT7N60 and how does it affect driver selection?

The AOT7N60 has a typical total gate charge (Q_g) of 22 nC at V_GS = 10 V. This value determines required gate driver peak current and influences switching speed and losses. A driver capable of ≥1 A peak current ensures <100 ns turn-on delay, critical for high-frequency flyback operation. The AOT7N60's Q_g enables use with common PWM ICs like UC3842 or VIPer22A without external buffer stages.

Can AOT7N60 be used in synchronous rectification configurations?

No, the AOT7N60 is not suitable for synchronous rectification. It is an N-channel high-side switch designed for primary-side switching in isolated topologies. Its body diode characteristics (120 ns t_rr, 7 A I_F) are not optimized for low-loss freewheeling, and its gate threshold (2–4 V) makes precise timing control difficult in secondary-side roles. Synchronous rectifiers require dedicated low-V_DS(on), low-Q_g, logic-level devices - the AOT7N60 is intended for primary-side high-voltage switching only.
