Overview
The CD1206-B220 is a surface mount Schottky barrier rectifier diode manufactured by Bourns Inc. in a compact 1206 (3216 metric) package. It features a maximum average forward rectified current of 2 A and a maximum repetitive peak reverse voltage of 20 V. The device exhibits a maximum instantaneous forward voltage of 0.5 V at 2 A and a DC reverse current of 0.5 mA at rated blocking voltage. It supports a peak forward surge current of 40 A and operates within a temperature range of -55 °C to +125 °C.
Feature Summary
- Lead-free construction compliant with RoHS standards
- Low profile molded plastic package for PCB real estate savings
- High current capability with UL 94V-0 classification
- Flat configuration minimizes roll-away on standard pick-and-place equipment
Applications
- High frequency switching power supplies
- Inverters
- Free wheeling circuits
- Polarity protection
Procurement Notes
Verify the specific part number suffix against official documentation to confirm electrical ratings, as variations exist within the series. Confirm compliance requirements such as RoHS status and lead finish specifications prior to ordering. Ensure that the intended application environment falls within the specified operating temperature range and does not involve life-critical or high-risk systems without explicit manufacturer authorization.
Selection Notes
Select this component when space constraints require a small form factor like the 1206 package while maintaining a 2 A current rating. Choose based on the required reverse voltage; the B220 variant provides a 20 V rating suitable for low-voltage applications. Consider the thermal resistance characteristics and derating curves if operating near maximum current limits or elevated ambient temperatures.
Part Context
This component belongs to the Bourns CD1206-B2xx series of surface mount Schottky rectifiers. The series includes variants with different reverse voltage ratings, specifically 20 V, 40 V, 60 V, and 100 V, all sharing the same physical package and general electrical characteristics regarding forward current and surge capacity.
Replacement Considerations
Direct substitutes within the same series include CD1206-B240, CD1206-B260, and CD1206-B2100, which offer higher reverse voltage ratings but share identical current capabilities and package dimensions.
