🎥 This quick video highlights key models in the Suntan Rectifier & Diode Series — ideal for engineers and sourcing professionals looking for compact, efficient, and reliable components in power circuitry.

Why Choose Rectifier & Diodes that Prioritize Power Efficiency and Design Flexibility?

In today’s compact, high-efficiency electronics, the choice of rectifier and diode components can significantly impact system performance, thermal behavior, and long-term reliability. Whether you're designing power modules, LED drivers, or consumer devices, your selection impacts performance, footprint, and cost.

Common Challenges in Power Conversion

• Heat Dissipation in Dense PCBs: Compact boards create thermal stress. Choosing components with low forward voltage drop and stable temperature response is key.
• Fast Switching Needs: In high-frequency applications, reverse recovery time and low leakage current directly affect power loss and EMI.
• Footprint Constraints: Limited PCB space favors compact packages like SMA, SOD-123, or DO-214AC.
• Surge & Reverse Voltage Protection: Many designs require built-in protection using TVS or Zener diodes.

What to Look for in a Reliable Diode Series

• ✅ Fast Recovery Time (<35ns ideal for high-frequency circuits)
• ✅ Low Forward Voltage Drop for better thermal efficiency
• ✅ RoHS / AEC-Q101 Compliance as needed by application
• ✅ Stable Electrical Performance across temperature & load
• ✅ Multiple Package Options for layout flexibility

Recommended Models by Application

Real-World Applications

• LED Drivers: Low-capacitance, fast recovery types prevent flicker and power loss
• EV Protection Modules: TVS/Zener with low clamping voltage ensures stability
• Industrial AC-DC Converters: Bridge rectifiers with high surge capability ensure longevity

Conclusion: Think Beyond the Part Number

The right rectifier or diode goes beyond datasheet numbers — it supports your design’s efficiency targets, regulatory needs, and layout constraints.

When reviewing your BOM or vendor list, consider solutions that offer consistent performance, durable packaging, and traceable quality.

All Kinds of Capacitors – Your Trusted Partner in Electronic Component

Suntan Technology Company Limited — All Kinds of Capacitors

When designing compact power systems, engineers often face the challenge of balancing performance, footprint, and reliability. The Suntan TS13C Series SMD Aluminum Electrolytic Capacitors are engineered to solve this problem by delivering stable performance in high-density layouts — without compromising on ripple endurance or temperature stability.

Compact Size Meets High Ripple Capability

The TS13C series is ideal for applications where board space is limited, but current demands are high. Key features include:

• Case sizes as small as Φ4×5.4mm
• Rated ripple current up to 1190mA (TS13CY)
• Extra low impedance options for switching power designs
• Stable ESR across a wide frequency range

This makes TS13C an excellent fit for compact devices such as adapters, display cards, and embedded system boards.

Sub-Series for Targeted Applications

• TS13C9: Extremely low leakage current, ideal for sensitive circuits
• TS13CD: Rated up to 400VDC, with 5,000-hour endurance
• TS13CW: Offers up to 10,000 hours of stable operation at 105°C
• TS13CR / TS13CY: Designed for high ripple, solvent-resistant environments
• TS13CJ: Specifically optimized for LED display boards

This modular approach ensures engineers can select the exact match for their application — whether it's for high-frequency ripple handling or extended service life in high-temperature conditions.

Proven Performance in Harsh Conditions

• Endurance from 2,000 to 10,000 hours
• Heat and reflow resistance
• Ripple current stability
• Low-temperature impedance consistency

These capacitors are suitable for reflow soldering and ensure minimal ESR drift, even after prolonged exposure to heat cycles and ripple load.

Application Scenarios

• Compact switching power supplies
• System boards and communication modules
• LED backlighting circuits
• Automotive and industrial controllers
• Power decoupling in high-speed digital circuits
