Product details

Overview

AO6701 from Alpha & Omega Semiconductor is a 30V P-Channel MOSFET with integrated Schottky diode in TSOP-6 package, featuring R_DS(ON) < 135 mΩ at V_GS = −10 V, −2.3 A continuous drain current, and bidirectional blocking capability for DC-DC conversion and load switching applications.

For engineers reviewing the AO6701 datasheet, pinout, applications, or equivalent options, key selection criteria include its trench-based low-R_DS(ON) performance, co-packaged Schottky diode enabling compact bidirectional switch designs, thermal resistance (R_θJA = 109.4 °C/W, t ≤ 10 s), and gate charge (Q_g = 4.9 nC) for efficient switching control.

Technical Context

The AO6701 integrates a P-Channel enhancement-mode MOSFET and a Schottky diode in a single TSOP-6 package, sharing source (S) and anode (A) terminals to enable synchronous rectification or reverse-polarity protection without external diodes. Its trench MOSFET architecture delivers low gate charge (Q_g = 4.9 nC) and fast switching (t_D(on) = 6.9 ns, t_f = 13.2 ns).

Thermal design is supported by dual thermal paths: junction-to-lead (R_θJL = 58.5 °C/W, steady-state) and junction-to-ambient (R_θJA = 109.4 °C/W, t ≤ 10 s). The Schottky diode provides V_F < 0.5 V at 0.5 A and ultrafast recovery (t_rr = 5.2 ns), critical for high-frequency DC-DC topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	−30 V - Maximum drain-source voltage rating; defines safe operating range for negative-rail switching.
R_DS(ON) @ V_GS = −10 V	< 135 mΩ - Enables low conduction loss at full gate drive; supports ≥2.3 A continuous current with minimal I²R heating.
Q_g	4.9 nC - Low total gate charge reduces driver power requirement and enables high-frequency PWM operation.
V_F @ I_F = 0.5 A	< 0.5 V - Schottky forward drop minimizes conduction loss in freewheeling paths of buck or synchronous rectifier stages.
t_rr (Schottky)	5.2 ns - Ultrafast reverse recovery eliminates switching loss and EMI in high-speed DC-DC converters.
R_θJA (t ≤ 10 s)	109.4 °C/W - Thermal resistance under pulsed conditions; informs short-duration power handling in transient loads.
I_D (continuous)	−2.3 A @ T_A = 25°C - Verified continuous current capability with standard PCB layout (1 in², 2 oz Cu).

Pinout & Package

AO6701 is housed in a thermally enhanced TSOP-6 surface-mount package with exposed leadframe for improved heat dissipation. Pin numbering follows standard top-view orientation (pin 1 = Gate, pin 2 = Drain, pin 3 = Source, pin 4 = Anode, pin 5 = Cathode, pin 6 = N/C).

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Controls MOSFET channel turn-on/off; requires −10 V for full enhancement; threshold V_GS(th) = −0.6 to −1.4 V.
2 (D)	Drain	High-side or low-side switched node; rated for −30 V breakdown; connects to input rail in high-side switch configurations.
3 (S)	Source	Common reference for MOSFET and Schottky; tied to system ground or output rail depending on topology.
4 (A)	Anode	Schottky anode terminal; internally connected to Source (S); used for reverse-current blocking or freewheeling path.
5 (K)	Cathode	Schottky cathode terminal; provides low-V_F path from K to A during reverse conduction; decouples MOSFET body diode limitations.
6 (N/C)	No Connect	Unused internal pad; must remain unconnected per datasheet; no electrical function or thermal role.

Key Features

Feature	Design Value
Integrated Schottky diode	Eliminates need for external freewheeling diode in buck converters and reverse-polarity protection circuits.

FAQ

What is the maximum continuous drain current rating for the AO6701?

The AO6701 is rated for −2.3 A continuous drain current at T_A = 25°C with standard PCB layout (1 in², 2 oz Cu). At elevated ambient temperatures (e.g., 70°C), derating applies per the datasheet's thermal curves; actual current depends on layout, airflow, and thermal interface. The AO6701 datasheet specifies −1.8 A at T_A = 70°C under identical conditions.

Does the AO6701 require an external Schottky diode for synchronous rectification?

No-the AO6701 integrates a Schottky diode with V_F < 0.5 V at 0.5 A and t_rr = 5.2 ns, eliminating the need for an external diode in synchronous rectifier or freewheeling applications. This integration reduces component count, PCB area, and parasitic inductance, directly improving efficiency and EMI performance in the AO6701-based design.

What is the gate threshold voltage range for the AO6701?

The AO6701 has a gate threshold voltage (V_GS(th)) range of −0.6 V to −1.4 V, measured at I_D = −250 µA and T_J = 25°C. This low-threshold range allows reliable turn-on with logic-level gate drivers (e.g., 3.3 V or 5 V microcontroller outputs), making the AO6701 suitable for low-voltage control interfaces without level-shifting circuitry.

Can the AO6701 be used in high-side switch configurations?

Yes-the AO6701 is a P-Channel MOSFET optimized for high-side switching, with V_DS = −30 V and R_DS(ON) < 135 mΩ at V_GS = −10 V. Its TSOP-6 pinout (G, D, S, A, K, N/C) supports direct connection to positive rails, and the integrated Schottky enables clean reverse-current blocking. Proper gate drive referencing to the source is required for robust AO6701 operation.

What is the thermal resistance from junction to ambient for the AO6701 under pulsed conditions?

The AO6701 has a junction-to-ambient thermal resistance (R_θJA) of 109.4 °C/W for pulse widths ≤ 10 seconds, measured on a 1 in² FR-4 board with 2 oz copper in still air. This value is critical for calculating peak junction temperature during transient loads; for continuous operation, the steady-state R_θJA is 136.5 °C/W, and the AO6701 datasheet provides normalized transient impedance curves for precise thermal modeling.
