CD1206-B240

Overview

The CD1206-B240 is a surface mount Schottky barrier rectifier diode manufactured by Bourns Inc. in a compact 1206 (3216 metric) package. It features a maximum repetitive peak reverse voltage of 40 V and supports a maximum average forward rectified current of 2 A. The device exhibits a typical thermal resistance of 75 °C/W (junction-to-ambient). Electrical characteristics include a maximum DC reverse current of 0.5 mA at rated blocking voltage and 25 °C, with a maximum instantaneous forward voltage of 0.7 V at 2 A. The component operates within a temperature range of -55 °C to +125 °C.

Feature Summary

• Constructed as a lead-free device compliant with RoHS directives.
• Features a flat configuration that minimizes roll-away issues during standard pick-and-place assembly.
• Includes UL 94V-0 classification for the encapsulation material.

Applications

• High frequency switching power supplies
• Inverters
• Free wheeling circuits
• Polarity protection

Procurement Notes

Verify the specific datasheet revision and latest electrical parameters directly from the manufacturer before finalizing designs. Confirm compliance with applicable regional regulations such as RoHS and REACH requirements. Ensure that the selected packaging format matches the automated assembly equipment capabilities. Review the legal disclaimers regarding high-risk applications and verify actual device performance under specific operating conditions.

Selection Notes

Select this component when a compact Schottky rectifier is required for 40 V reverse voltage applications. The 1206 footprint offers space efficiency for portable communications and computing devices. Consider the 2 A current rating and low forward voltage drop for efficient rectification. Verify thermal management requirements against the specified junction-to-ambient thermal resistance values.

Part Context

This part belongs to the CD1206-B220~B2100 series of surface mount Schottky rectifier diodes. The series provides options ranging from 20 V to 100 V repetitive peak reverse voltage while maintaining a consistent 2 A forward current capability. All variants share the same 1206 package dimensions and general physical specifications, differing primarily in their voltage ratings.

Replacement Considerations

Other members of the CD1206-B220~B2100 series may serve as substitutes if voltage ratings align with circuit requirements. Cross-reference with other manufacturers offering 1206 Schottky diodes with equivalent 40 V reverse voltage and 2 A forward current specifications. Verify pinout compatibility and thermal characteristics before implementation.
