Diodes Incorporated Releases Its First Silicon Carbide Schottky Barrier Diodes (SBD)
Diodes Incorporated (Nasdaq: DIOD) has launched its first Silicon Carbide (SiC) Schottky barrier diodes (SBDs), enhancing its product portfolio. This new range includes the DSCxxA065 series with 11 products rated at 650V and the DSCxx120 series with 8 products rated at 1200V. These diodes are designed for applications such as AC-DC conversion, photovoltaic inverters, and industrial motor drives. Notable features include negligible switching losses, low forward voltage, reduced heat dissipation, and high surge current capability, contributing to system efficiency and reliability. Pricing ranges from $1.24 to $6.68 for bulk orders.
- Launch of first SiC Schottky barrier diodes, expanding product offerings.
- Significantly improved efficiency and high-temperature reliability.
- Lower operational costs due to reduced heat dissipation and power losses.
- Broad application suitability including energy-efficient devices and industrial uses.
- None.
These wide-bandgap SBDs bring the benefits of significantly improved efficiency and high-temperature reliability, while also responding to market demands for reduced system running costs and low maintenance. The devices are suitable for AC-DC, DC-DC, and DC-AC switching converters, photovoltaic inverters, uninterruptable power supplies, and industrial motor drive applications. These devices can also be used in a variety of other circuits, such as boost converters for power factor correction.
The efficient performance of these SiC devices are superior to those of conventional silicon-based products, and provide power supply designers with uncompromising product performance benefits, such as:
- Negligible switching losses due to low capacitive charge (QC) that provide high efficiency in fast switching applications. This is suitable for circuit designs with higher power density and smaller overall solution size.
- Low forward voltage (VF) that further improves efficiency, reducing power losses and operational costs.
- Reduced heat dissipation that helps lower overall system cooling budgets.
- High surge current capability that increases robustness for better system reliability, while excellent thermal performance reduces build costs.
Three package options include surface mount TO252-2 (Type WX), through-hole TO220AC (Type WX), and ITO220AC (Type WX-NC).
