In DC-DC conversion modules, lithium battery powered devices, IoT hardware, and mini power adapters, high-frequency rectification, freewheeling circuits, and anti-reverse protection require diodes with low conduction loss, strong surge tolerance, and compact SMD packaging. The Slkor RB160M-40 is a SOD-123FL surface-mount Schottky barrier diode. Adopting advanced Schottky barrier technology, it features low forward voltage drop, 40V reverse withstand voltage and 1A continuous rectification current. With fast high-frequency switching capability, it delivers highly efficient power conversion and is ideal for compact PCB layout and low-voltage high-efficiency power supply designs.
1. Core Electrical Parameters
Forward Voltage (Vf): 460mV @ 1A DC Reverse Voltage (Vr): 40V Average Rectified Current: 1A Reverse Leakage Current (Ir): 30μA @ 40V Non-repetitive Peak Surge Current (Ifsm): 30A Package: SOD-123FL
2. Core Product Advantages
2.1 Ultra-low Forward Voltage Drop, Low Power Loss
The RB160M-40 achieves a typical forward voltage drop of only 460mV at 1A operating current. Its low conduction loss significantly reduces heat generation during continuous operation, improves overall power conversion efficiency, and eases thermal design pressure for long-running electronic equipment.
2.2 Excellent Anti-surge Impact Resistance
It supports a non-repetitive peak surge current of 30A, effectively resisting instantaneous current shocks caused by power-on transients and sudden load changes. This greatly enhances circuit stability and protects peripheral components from surge damage.
2.3 Fast Switching for High-frequency Applications
Benefiting from the Schottky barrier structure with negligible minority carrier storage effect, the diode delivers ultra-fast switching speed. It performs excellently in high-frequency rectification and freewheeling scenarios such as DC-DC converters and switching power supplies, effectively reducing switching losses.
2.4 Compact SOD-123FL SMD Package
Packaged in standard SOD-123FL, the RB160M-40 features ultra-small size, saves PCB layout space, and supports fully automatic SMT mass production. It perfectly matches the miniaturization and lightweight trends of modern consumer and industrial electronic products.
3. Main Applications
With well-balanced electrical performance, the Slkor RB160M-40 is widely applied in low-voltage circuit scenarios, including DC-DC step-up/step-down modules, lithium battery charging management circuits, IoT modules, LED driver power supplies, consumer electronics, signal freewheeling circuits, power anti-reverse connection protection, and miniature industrial control boards.
4. Engineering Design Guidelines
1. As a Schottky device, the RB160M-40 has relatively higher reverse leakage current than conventional silicon rectifier diodes. Designers should evaluate leakage impact on precision weak-signal circuits.
2. Proper PCB copper area layout is required for heat dissipation under high continuous current conditions. Current derating is recommended for high-temperature working environments.
3. The 30A surge current is a non-repetitive peak parameter for short-term pulse tolerance and cannot be used for continuous operation.
4. Follow standard SOD-123FL reflow soldering profiles to avoid device performance degradation caused by excessive temperature and prolonged heating.
5. Product Summary
The Slkor RB160M-40 SMD Schottky diode integrates low forward loss, strong surge resistance, high-speed switching and compact packaging. Its 40V voltage rating and 1A current capacity cover most low-voltage consumer and industrial circuit requirements. As a cost-effective and reliable domestic solution for high-frequency rectification, freewheeling and anti-reverse protection, it is suitable for new project development and mainstream device replacement.
