Product details

Overview

AOY2N60 from Alpha & Omega Semiconductor is a 600 V, 2 A N-channel enhancement-mode MOSFET in TO-251B package, featuring R_DS(ON) ≤ 4.7 Ω at V_GS = 10 V, 100% UIS-tested ruggedness, and gate threshold voltage of 3.4–4.5 V. It serves as a high-voltage switching element in offline AC/DC power supplies and LED lighting drivers.

For engineers reviewing the AOY2N60 datasheet, pinout, applications, or equivalent options, key selection considerations include its 700 V avalanche-rated drain-source breakdown, 1.8 Ω junction-to-case thermal resistance, 6.5–11 nC total gate charge, and suitability for flyback and buck converters operating up to 150 °C junction temperature.

Technical Context

The AOY2N60 employs advanced high-voltage trench MOSFET technology optimized for low conduction loss and fast switching. Its static parameters include BVDSS = 700 V (TJ = 150 °C), R_DS(ON) = 3.9–4.7 Ω (V_GS = 10 V), and V_GS(th) = 3.4–4.5 V - enabling reliable turn-on with standard 10 V gate drivers.

Dynamically, it delivers C_iss = 295 pF, C_rss = 2.3 pF, Q_g = 6.5–11 nC, and t_r/t_f = 11/14 ns (R_G = 25 Ω), supporting high-frequency operation while maintaining low EMI. The device is 100% tested for repetitive avalanche energy (E_AS = 57 mJ) and gate resistance (R_g = 3.2 Ω).

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP2NK60ZFP	R_DS(ON) = 5.5 Ω (higher), Q_g = 12 nC (higher), TO-220FP package	Higher thermal resistance (R_θJC = 3.5 °C/W) limits power density in compact layouts	Prefer AOY2N60 for space-constrained SMT designs requiring lower gate drive loss

FAQ

What is the maximum continuous drain current for AOY2N60 at 100 °C case temperature?

The AOY2N60 supports 1.4 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits under real-world heatsink conditions and ensures safe operation without exceeding 150 °C junction temperature. The AOY2N60 datasheet provides Figure 13 for precise current de-rating curves across case temperatures.

Does AOY2N60 have avalanche capability, and is it production-tested?

Yes, AOY2N60 is 100% production-tested for Unclamped Inductive Switching (UIS) with E_AS = 57 mJ at T_J = 25 °C. This validated ruggedness ensures reliable operation in flyback and forward converters with leakage inductance, eliminating need for external snubbers in many designs. The AOY2N60 specification sheet explicitly states "100% UIS Tested" in the Product Summary.

What is the gate threshold voltage range for AOY2N60, and how does it affect drive requirements?

The AOY2N60 has a gate threshold voltage V_GS(th) of 3.4–4.5 V at T_J = 25 °C. This range ensures turn-on with standard 5 V logic-level drivers while maintaining noise immunity. For full enhancement, V_GS ≥ 10 V is required to achieve R_DS(ON) ≤ 4.7 Ω. The AOY2N60 Electrical Characteristics table confirms this behavior across temperature and current conditions.

Can AOY2N60 be used in place of TO-220 MOSFETs like FQP2N60 in existing designs?

No - AOY2N60 uses TO-251B (IPAK) surface-mount packaging, while FQP2N60 uses through-hole TO-220. Direct replacement requires PCB layout revision. However, AOY2N60 offers lower R_θJC (2.2 vs. 3.0 °C/W) and guaranteed UIS testing not present in FQP2N60. When redesigning, the AOY2N60 enables higher power density and improved surge resilience.

What is the body diode reverse recovery time (t_rr) and charge (Q_rr) for AOY2N60?

The AOY2N60 body diode exhibits t_rr = 268 ns and Q_rr = 1.6 μC under IF = 2 A, dI/dt = 100 A/μs, and V_DS = 100 V conditions. These values are measured per JEDEC standards and support use in quasi-resonant topologies where low reverse recovery loss is critical. The AOY2N60 datasheet lists these parameters in the Switching Parameters section on page 2.
