Product details
Overview
AOTF11N62L from Alpha & Omega Semiconductor is a 620 V, 11 A N-channel enhancement-mode MOSFET in TO-220F package, featuring RDS(on) ≤ 0.65 Ω at VGS = 10 V, 100% UIS tested, and qualified for consumer-grade offline AC-DC power supplies.
For engineers reviewing the AOTF11N62L datasheet, pinout, applications, or equivalent options, key selection factors include avalanche ruggedness (EAS = 39 mJ), low gate charge (Qg = 24–37 nC), body-diode reverse recovery performance (trr = 400–600 ns), and thermal resistance (RθJC = 3.2 °C/W).
Technical Context
The AOTF11N62L employs high-voltage trench-gate process technology optimized for hard-switched offline flyback and LLC resonant converters. Its low Ciss (1320–1990 pF) and Crss (6.5–16 pF) reduce switching losses, while guaranteed unclamped inductive switching (UIS) capability supports robust operation under transient overloads.
Designed for primary-side switching in universal-input AC-DC adapters and open-frame power supplies, it operates with VGS(th) = 3.3–4.5 V and supports gate drive from standard 10 V controllers. The device's halogen-free construction (denoted by "L" suffix) complies with IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 620 V - Supports 380 V DC bus with 60% margin for surge and ringing in offline SMPS. |
| RDS(on) @ VGS=10 V | ≤ 0.65 Ω - Enables <1.5 W conduction loss at 11 A continuous drain current in TO-220F package. |
| Qg | 24–37 nC - Determines gate driver strength requirement; compatible with common PWM ICs like UC384x series. |
| EAS | 39 mJ - Confirmed single-pulse avalanche energy rating ensures reliability during output short-circuit events. |
| trr | 400–600 ns - Body diode recovery time impacts efficiency and EMI in quasi-resonant and ZVS topologies. |
| RθJC | 3.2 °C/W - Junction-to-case thermal resistance enables ~40 W power dissipation with moderate heatsinking at TC = 100 °C. |
| ID @ TC=25°C | 11 A - Continuous drain current rating under ideal heatsink conditions; derates to 8 A at TC = 100 °C. |
Pinout & Package
Package: TO-220F (full-pack, insulated tab). Molded plastic case with isolated metal tab for direct heatsink mounting without insulator washer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Drain) | Main high-side current path | Connected to primary winding of transformer or bulk DC bus; carries full switching current and voltage stress. |
| G (Gate) | Control terminal | Receives PWM signal; requires low-impedance drive due to Qg = 24–37 nC and Rg = 1.7–5.3 Ω. |
| S (Source) | Reference node / return path | Common connection point for current sense resistor and gate driver ground; defines local reference for VGS. |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested | Guarantees avalanche survival under worst-case inductive turn-off transients without derating. |
| 100% Rg tested | Ensures consistent gate drive timing and reduces risk of shoot-through in half-bridge configurations. |
| Halogen-free (L suffix) | Meets IEC 61249-2-21 and RoHS-compliant manufacturing requirements for consumer electronics. |
| Low Ciss/Crss ratio | Reduces Miller-induced false turn-on and improves noise immunity in high-dV/dt environments. |
| Enhanced body diode softness | Minimizes voltage overshoot and EMI during reverse recovery in discontinuous conduction mode (DCM). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP12NK60ZFP | 600 V, 12 A, RDS(on) = 0.65 Ω, TO-220FP package, no UIS rating specified | Lacks guaranteed avalanche testing; lower VDS margin for 380 V DC bus | Acceptable where surge immunity is managed externally; verify SOA under unclamped inductive loads. |
| FQP10N60CTU | 600 V, 10 A, RDS(on) = 0.75 Ω, TO-220 package, no "L" halogen-free marking | Higher conduction loss; non-halogen-free; RθJC = 3.5 °C/W vs. 3.2 °C/W | Suitable for cost-sensitive consumer designs without strict environmental compliance requirements. |
Compared with STP12NK60ZFP and FQP10N60CTU, the AOTF11N62L provides superior avalanche ruggedness, tighter gate threshold control, and halogen-free certification-critical for modern AC-DC adapters requiring long-term reliability and regulatory compliance.

FAQ
What is the maximum junction temperature rating for the AOTF11N62L?
The AOTF11N62L has a maximum junction temperature (TJ) rating of 150 °C, validated per absolute maximum ratings table. This limit governs thermal design margins when calculating allowable power dissipation using RθJC = 3.2 °C/W and case temperature constraints. Operation beyond 150 °C risks permanent parametric shift or failure. The AOTF11N62L datasheet specifies derating curves confirming safe operation up to this ceiling under defined pulse and DC conditions.
Does the AOTF11N62L support gate drive at 5 V logic levels?
No, the AOTF11N62L is not fully enhanced at 5 V gate drive. Its gate threshold voltage (VGS(th)) ranges from 3.3 V to 4.5 V, but RDS(on) is only guaranteed ≤ 0.65 Ω at VGS = 10 V. At 5 V, the device operates in linear region with significantly higher on-resistance-unsuitable for efficient switching. The AOTF11N62L requires ≥10 V gate drive for rated conduction performance and optimal switching efficiency.
Is the AOTF11N62L pin-compatible with the non-halogen version AOTF11N62?
Yes, the AOTF11N62L is mechanically and electrically pin-compatible with AOTF11N62. Both share identical TO-220F package, pinout (D-G-S), and electrical specifications-including same RDS(on), Qg, and avalanche ratings. The sole difference is halogen-free material composition (per IEC 61249-2-21), reflected only in the "L" suffix. No PCB or schematic changes are needed when substituting AOTF11N62L for AOTF11N62 in existing designs.
What is the body diode forward voltage of the AOTF11N62L at 11 A?
The body diode forward voltage (VSD) of the AOTF11N62L is 0.73–1.0 V at IS = 11 A and TJ = 25 °C, per electrical characteristics table. This parameter directly affects conduction loss and thermal rise during synchronous rectification or freewheeling intervals. The AOTF11N62L's relatively low VSD contributes to reduced heat generation compared to alternatives with higher intrinsic diode drops, especially in DCM flyback or active-clamp forward converters.
How does the AOTF11N62L's RθJC compare to standard TO-220 devices?
The AOTF11N62L has RθJC = 3.2 °C/W, measured junction-to-case under standardized test conditions. This is competitive for TO-220F packages-slightly higher than some ultra-low-RθJC variants (e.g., 2.5 °C/W), but optimized for insulation integrity and manufacturability. The AOTF11N62L's value reflects its full-pack construction, enabling reliable thermal transfer to heatsinks while maintaining creepage/clearance compliance. Designers should use this exact value-not generic TO-220 averages-to calculate real-world junction temperature rise.
