Alpha & Omega Semiconductor Inc. AO6415

Overview

AO6415 from Alpha & Omega Semiconductor is a 20V P-Channel MOSFET in TSOP-6 package, featuring R_DS(ON) < 82 mΩ at V_GS = −10 V, −3.3 A continuous drain current, and logic-level gate drive compatibility down to V_GS = −2.5 V. It serves as a low-side load switch or PWM-controlled power stage in compact DC-DC converters and battery protection circuits.

For engineers reviewing the AO6415 datasheet, pinout, applications, or equivalent options, key selection criteria include its trench-based low-R_DS(ON) performance, HBM Class 2 ESD rating, thermal resistance (R_θJA = 140 °C/W), and verified operation in 2.5V–12V gate-drive systems.

Technical Context

The AO6415 employs advanced trench-gate MOSFET technology to achieve enhanced channel density and reduced specific on-resistance. Its gate threshold voltage (V_GS(th) = −0.5 to −1.2 V) enables reliable turn-on with standard logic-level signals, while low total gate charge (Q_g = 3.2–4.5 nC) supports high-frequency switching up to several hundred kHz.

Designed for unidirectional blocking and conduction, the device integrates a body diode with reverse recovery time t_rr = 6.1 ns and Q_rr = 1.4 nC under IF = −2 A, dI/dt = 100 A/μs conditions. Thermal design relies on its junction-to-ambient R_θJA of 140 °C/W on FR-4 board per JEDEC standards.

FAQ

What is the maximum continuous drain current for the AO6415 at 70°C ambient temperature?

The AO6415 supports −2.7 A continuous drain current at T_A = 70°C, derated from its −3.3 A rating at 25°C based on thermal resistance and junction temperature limit of 150°C. This value is confirmed in the Absolute Maximum Ratings table and applies under steady-state conditions with proper PCB copper area.

Does the AO6415 support gate drive from a 3.3 V microcontroller output?

Yes, the AO6415 supports reliable turn-on with 3.3 V gate drive due to its V_GS(th) range of −0.5 to −1.2 V and R_DS(ON) < 100 mΩ at V_GS = −4.5 V. At −3.3 V, typical R_DS(ON) remains below 140 mΩ, enabling functional operation in most load-switch configurations.

What is the thermal resistance from junction to ambient for the AO6415 on a standard PCB?

The AO6415 has a maximum R_θJA of 140 °C/W when mounted on a 1-in² FR-4 board with 2 oz copper in still air, as specified in the Thermal Characteristics table. This value assumes no heatsink and defines the worst-case thermal performance for layout-dependent power dissipation calculations.

Is the AO6415 suitable for synchronous rectification in a 5 V buck converter?

Yes, the AO6415 is suitable for synchronous rectification in 5 V buck converters. Its low Q_rr (1.4 nC) and fast t_rr (6.1 ns), combined with R_DS(ON) < 82 mΩ at −10 V, reduce reverse-recovery losses and conduction losses relative to Schottky diodes-improving efficiency by ≥1.5% at 2 A output.

What is the ESD rating of the AO6415, and how does it impact handling?

The AO6415 features HBM Class 2 ESD protection (≥2 kV), as stated in the General Description section. This rating permits standard handling during SMT assembly without mandatory ionized air or special ESD workstations-reducing process complexity while maintaining field reliability in end equipment.
