The **UD4606G-S08-R** is a high-performance complementary (N-Channel and P-Channel) MOSFET power transistor manufactured by UTC (Unisonic Technologies). It is designed to minimize on-state resistance and provide reliable switching performance in a compact package. --- ### 1. General Specifications The UD4606G consists of two separate MOSFETs integrated into a single 8-pin package. | Feature | N-Channel (CH1) | P-Channel (CH2) | | :--- | :--- | :--- | | **Drain-Source Voltage ($V_{DSS}$)** | 30V | -30V | | **Gate-Source Voltage ($V_{GSS}$)** | ±20V | ±20V | | **Continuous Drain Current ($I_D$)** | 6.0A | -6.0A | | **Pulsed Drain Current ($I_{DM}$)** | 20A | -20A | | **Static Drain-Source On-Resistance ($R_{DS(ON)}$)** | 28mΩ (typ) @ 10V | 35mΩ (typ) @ -10V | --- ### 2. Key Features * **Complementary Pair:** Contains both an N-Ch and a P-Ch MOSFET, making it ideal for H-bridge or half-bridge applications. * **Low On-Resistance:** Reduces power loss during conduction. * **Fast Switching:** Optimized for high-frequency DC-DC conversion. * **Halogen-Free:** The "G" suffix indicates it is a "Green" (Halogen-free and RoHS compliant) product. * **Package Type:** **SOP-8** (Surface Mount Device), suitable for automated assembly. --- ### 3. Pin Configuration (SOP-8) The device uses a standard 8-pin layout to provide access to the individual Source, Gate, and Drain terminals for both channels. | Pin Number | Name | Description | | :--- | :--- | :--- | | 1 | S1 | Source (N-Channel) | | 2 | G1 | Gate (N-Channel) | | 3 | S2 | Source (P-Channel) | | 4 | G2 | Gate (P-Channel) | | 5, 6 | D2 | Drain (P-Channel) | | 7, 8 | D1 | Drain (N-Channel) | --- ### 4. Typical Applications The UD4606G is commonly found in battery-powered devices and power management circuits: 1. **Motor Drivers:** Small DC motor control using H-bridge configurations. 2. **LCD Backlight Inverters:** Used to switch power for display backlighting. 3. **DC-DC Converters:** Buck/Boost conversion in laptops and tablets. 4. **Load Switching:** Efficiently turning off specific power rails to save energy. ---
