## Overview of the BAS416V The **BAS416V** is a high-speed switching diode housed in a very small, surface-mount plastic package. It is designed for high-speed switching applications and is characterized by its extremely low leakage current and low capacitance. --- ### 1. Key Technical Specifications The following table outlines the primary electrical characteristics of the BAS416V: | Parameter | Symbol | Maximum Value | Unit | | :--- | :--- | :--- | :--- | | **Continuous Reverse Voltage** | $V_R$ | 75 | V | | **Repetitive Peak Reverse Voltage** | $V_{RRM}$ | 85 | V | | **Forward Current (DC)** | $I_F$ | 200 | mA | | **Repetitive Peak Forward Current** | $I_{FRM}$ | 500 | mA | | **Reverse Recovery Time** | $t_{rr}$ | 3.0 | µs | | **Reverse Current (at $V_R = 75V$)** | $I_R$ | 5 | nA | | **Diode Capacitance** | $C_d$ | 1.1 | pF | --- ### 2. Physical and Package Details The BAS416V is typically found in the **SOD-523 (SC-79)** package. This is an ultra-small, leadless (or very short lead) plastic package ideal for space-constrained designs like mobile phones or wearable electronics. #### Pin Configuration The device has two terminals: 1. **Cathode:** Indicated by a bar/band on the body. 2. **Anode:** The opposite terminal. --- ### 3. Core Features and Benefits * **Low Leakage Current:** With a typical leakage of only a few nanoamperes (nA), it is excellent for battery-powered devices where power conservation is critical. * **Low Capacitance:** A capacitance of roughly 1.1 pF allows the diode to be used in high-frequency signal paths without significantly distorting the signal. * **Small Footprint:** The SOD-523 package saves significant PCB real estate. * **High Reliability:** Designed for automated assembly and high-speed switching. --- ### 4. Typical Applications The BAS416V is commonly used in the following scenarios: * **Mobile Communication:** Signal clamping and protection in cell phones. * **General-purpose Switching:** In circuits requiring fast response times. * **Reverse Polarity Protection:** Protecting low-power circuits from incorrect battery insertion. * **Ultra High-Speed Logic:** Due to its low $t_{rr}$ and low $C_d$. ---
