CDBV130-G Schottky Diode Equivalent & Substitute Parts

Part Overview

The CDBV130-G is a Schottky rectifier diode manufactured by Comchip Technology, rated for 30V DC reverse voltage and 1A average rectified current in a surface mount SOD-323 package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement continuity. The CDBV130-G maintains full electrical and mechanical compatibility with its active substitute, differing only in product status and packaging configuration.

Substitute Part Grouping Explanation

Substitution of the CDBV130-G with the CDBV130-HF is based on identical electrical performance across all critical parameters. Both parts share the same base product number (CDBV130) and maintain equivalent specifications for reverse voltage rating, forward voltage drop, rectified current capacity, recovery speed, reverse leakage current, and junction capacitance. The substitution is valid because the electrical characteristics that determine circuit performance are identical between the two part numbers. The primary distinction is product status: CDBV130-G is obsolete while CDBV130-HF is active, and packaging configuration differs (standard packaging versus Tape & Reel).

Key Parameters Determining Substitution:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 550 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 1 mA @ 200 V
• Capacitance @ Vr, F: 120 pF @ 4V, 1MHz
• Package / Case: SC-76, SOD-323
• Operating Temperature - Junction: -40°C to 125°C

Engineering Selection Recommendations

The CDBV130-HF is the direct active equivalent for the obsolete CDBV130-G. Selection of CDBV130-HF is appropriate for new designs and procurement of replacement inventory. Both parts are ROHS3 compliant and carry identical electrical specifications, ensuring functional equivalence in circuit applications. The CDBV130-HF is supplied in Tape & Reel packaging, which is standard for high-volume manufacturing and automated assembly processes. The transition from CDBV130-G to CDBV130-HF requires no circuit redesign, PCB layout modification, or thermal management adjustment, as all electrical and thermal characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can CDBV130-HF be used as a direct replacement for CDBV130-G in existing designs?
