Overview
The CD214A-S1Q is a glass passivated rectifier chip diode from the CD214A-S1x series, manufactured by Bourns Inc. It utilizes a compact SMA (DO-214AC) compatible surface-mount package designed for high-efficiency rectification in space-constrained environments. The device supports a maximum average forward current of 1 A and withstands a maximum repetitive peak reverse voltage of 1200 V. Key electrical characteristics include a typical junction capacitance of 12 pF at 4 V reverse bias and a maximum instantaneous forward voltage of 1.1 V at 1 A. It operates within a temperature range of -65 °C to +175 °C.
Feature Summary
- Glass passivation provides robust protection against environmental degradation and ensures stable performance under varying thermal conditions.
- Low profile SMA-compatible footprint enables significant PCB real estate savings while maintaining compatibility with standard surface-mount assembly equipment.
- High surge current capability allows reliable operation during transient load events without compromising device integrity.
Applications
- Switch Mode Power Supplies
- DC/DC Converters
- Portable equipment batteries
- Telecommunications
Procurement Notes
Verify the specific datasheet revision and ordering suffixes before procurement, as specifications are subject to change without notice. Confirm that the component meets all applicable regulatory requirements for your target market, including RoHS compliance and halogen-free status definitions provided by the manufacturer. Ensure proper handling procedures are followed given the ESD classification.
Selection Notes
Select this component when designing circuits requiring high-voltage rectification up to 1200 V in a compact form factor. Consider the 1.1 V forward voltage drop and 12 pF junction capacitance for efficiency and high-frequency performance requirements. Evaluate the thermal resistance parameters to ensure adequate heat dissipation within the specified operating junction temperature range of -65 °C to +175 °C.
Part Context
This part belongs to the CD214A-S1x series of glass passivated rectifiers, which offers a range of peak reverse voltages from 200 V to 1600 V. All variants share the same 1 A average forward current rating and DO-214AC compatible package dimensions. The series is engineered to meet the miniaturization demands of modern portable electronics and industrial power systems.
Replacement Considerations
Other parts within the CD214A-S1x series may serve as substitutes if their voltage ratings align with circuit requirements. For example, CD214A-S1M (1000 V) or CD214A-S1Y (1600 V) offer different voltage margins. Verify pinout compatibility and thermal characteristics before substitution.
