CDBA260SLR-HF Schottky Diode Equivalent & Substitute Parts

Part Overview

The CDBA260SLR-HF is a Schottky rectifier diode manufactured by Comchip Technology, rated for 60V DC reverse voltage and 2A average rectified current in a DO-214AC (SMA) surface mount package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. The fast recovery characteristic (≤500ns at >200mA) and low forward voltage drop make this diode suitable for high-frequency switching and power conversion applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDBA260SLR-HF is determined by the following critical electrical and mechanical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) Maximum: 60V minimum
• Package / Case: DO-214AC (SMA) surface mount
• Technology: Schottky rectifier diode
• Speed Classification: Fast Recovery ≤500ns at >200mA

Allowable Parameter Variations:

• Current - Average Rectified (Io): Equal to or greater than 2A
• Voltage - Forward (Vf): May exceed 500mV at rated current
• Current - Reverse Leakage: May be lower than 500µA
• Operating Temperature Range: May exceed -50°C to 150°C
• Capacitance: May differ from 30pF specification

The B360AM-13-F from Diodes Incorporated meets all mandatory matching criteria and provides enhanced electrical performance with higher current rating (3A) and improved reverse leakage characteristics (100µA), making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The B360AM-13-F is a suitable substitute for the CDBA260SLR-HF based on the following engineering factors:

Electrical Compatibility: Both devices share identical voltage ratings (60V DC reverse) and fast recovery speed classification (≤500ns at >200mA). The substitute's higher current rating (3A versus 2A) provides design margin without compromising performance in applications originally specified for 2A operation.

Package and Mounting: Both components use the DO-214AC (SMA) surface mount package, ensuring mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Product Status and Availability: The CDBA260SLR-HF is obsolete, while the B360AM-13-F is actively produced by Diodes Incorporated. This transition ensures long-term supply chain continuity and procurement reliability.

Compliance and Certification: The B360AM-13-F carries ROHS3 compliance and AEC-Q101 automotive qualification, providing enhanced regulatory alignment and quality assurance compared to the main part's unspecified compliance status.

Thermal Performance: The substitute's extended operating temperature range (-55°C to 150°C versus -50°C to 150°C) accommodates broader environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the B360AM-13-F directly replace the CDBA260SLR-HF without circuit modifications?

A: Yes. Both devices share the same 60V voltage rating, DO-214AC package, and fast recovery speed classification. The substitute's higher 3A current rating is backward compatible with 2A applications. No circuit modifications are required for pin-compatible substitution.

Q: What is the significance of the higher forward voltage drop in the B360AM-13-F (700mV @ 3A versus 500mV @ 2A)?

A: Forward voltage specifications are measured at different current levels. The B360AM-13-F is rated at 3A, while the CDBA260SLR-HF is rated at 2A. Direct comparison at identical current levels would require interpolation. At the original 2A operating point, the B360AM-13-F would exhibit lower forward voltage than its 3A specification indicates.

Q: Does the higher capacitance of the B360AM-13-F (130pF versus 30pF) affect circuit performance?

A: Capacitance differences may impact high-frequency switching applications. The substitute's higher capacitance could affect switching speed and EMI characteristics. Circuit-level evaluation is necessary for applications with strict frequency or noise requirements.

Q: Is the B360AM-13-F suitable for automotive applications?

A: Yes. The B360AM-13-F carries AEC-Q101 automotive qualification, making it suitable for automotive-grade applications. The CDBA260SLR-HF's automotive qualification status is not specified in the provided data.

Q: What is the impact of the substitute's lower reverse leakage current (100µA versus 500µA)?

A: Lower reverse leakage current represents improved device performance and reduced power dissipation in reverse bias conditions. This is a beneficial characteristic that does not compromise substitution compatibility.

Q: Are there any supply chain advantages to using the B360AM-13-F?

A: Yes. The B360AM-13-F is actively produced by Diodes Incorporated with 1651 pieces in stock, compared to the CDBA260SLR-HF's obsolete status. This ensures reliable long-term availability and procurement continuity.
