For engineers designing power converters or SMPS systems, reliability and efficiency start with choosing the right rectifier diode. Suntan provides a complete range of surface mount rectifiers from 100 V to 600 V and 2 A to 5 A, covering both fast recovery and Schottky types for industrial, LED, and telecom applications.
1. Comprehensive Voltage and Current Coverage
Suntan’s lineup includes:
- ES2J (600 V / 2 A, SMB) – Fast recovery rectifier for AC/DC conversion.
- RS3M (1000 V / 3 A, SMC) – General-purpose power rectifier for industrial control.
- SS310 (100 V / 3 A, SMA) – Schottky type for low-loss DC stages.
- SS510 (100 V / 5 A, SMC) – High-current Schottky for LED drivers and telecom PSUs.
This range ensures optimal matching of voltage, current, and package size (SMA–SMC) across multiple power topologies.
2. Thermal and Electrical Reliability
All Suntan rectifiers feature:
- High surge current capability (IFSM) for transient protection.
- Low forward voltage (VF) for reduced conduction loss.
- Stable thermal resistance (RθJC < 25°C/W) enabling compact PCB designs.
These parameters are critical in switch-mode power supplies (SMPS), DC bus rectifiers, and power adapters, where continuous load cycles require long-term junction reliability.
3. Application Scenarios
| Application | Recommended Series | Notes |
|---|---|---|
| SMPS input stage | ES2J / RS3M | Fast recovery, high voltage withstand |
| DC–DC output stage | SS310 / SS510 | Low VF Schottky type, high efficiency |
| LED driver & adapter | SS510 | Low thermal loss, high current |
| Telecom & networking | RS3M | 600–1000 V reliability |
4. Engineering Support and Resources
