B330CE-13 Equivalent & Substitute Parts

Part Overview

The B330CE-13 is a Schottky rectifier diode rated for 30 V DC reverse voltage and 3 A average rectified current in a Surface Mount DO-214AB (SMC) package. Manufactured by Diodes Incorporated, this component is classified as Obsolete. Due to its obsolete status and limited availability, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production requirements. Substitute parts maintain the core electrical specifications while offering improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution of the B330CE-13 is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 30 V
Current - Average Rectified (Io): 3 A
Voltage - Forward (Vf) (Max) @ If: 500 mV @ 3 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Technology: Schottky
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount

All substitute parts listed maintain these core electrical specifications and physical package requirements. Variations in secondary parameters such as reverse leakage current, capacitance, and operating temperature range do not disqualify substitution when primary criteria are met. Product status and compliance certifications are provided for design decision support but do not alter electrical compatibility.

Engineering Selection Recommendations

Primary Recommendation: B330-13-F

The B330-13-F is the direct manufacturer equivalent from Diodes Incorporated with Active product status. It maintains all primary electrical specifications and is available in Cut Tape and Digi-Reel packaging formats. This part is the preferred replacement for B330CE-13 in new designs and production transitions.

Secondary Recommendation: B330Q-13-F

The B330Q-13-F is an automotive-grade variant (AEC-Q101 qualified) from Diodes Incorporated with Active status. It maintains the full operating temperature range (-55°C ~ 150°C) and is suitable for applications requiring automotive qualification. Available in Tape & Reel packaging.

Alternative Recommendations: SS33HE3_B/H and SS33HE3_B/I

Both Vishay variants are automotive-grade (AEC-Q101 qualified) with Active product status. These parts maintain full electrical specifications and operating temperature range. Available in Tape & Reel packaging with Unlimited Moisture Sensitivity Level (MSL 1).

Not Recommended for New Designs: SK33-TP

The SK33-TP from Micro Commercial Co carries a "Not For New Designs" status. While electrically equivalent, this designation indicates the manufacturer does not recommend its use in new product development.

Compliance Note:

All substitute parts are ROHS3 compliant. The B330-13-F is REACH Unaffected, while B330CE-13 is REACH Affected. Verify REACH compliance requirements for your specific application and supply chain.

Frequently Asked Questions (FAQ)

Q: Can B330-13-F directly replace B330CE-13 in existing designs?

A: Yes. The B330-13-F maintains all primary electrical specifications: 30 V reverse voltage, 3 A average rectified current, 500 mV forward voltage at 3 A, and fast recovery characteristics. Both use the DO-214AB (SMC) Surface Mount package. The primary difference is product status (Active vs. Obsolete) and packaging format availability.

Q: What is the difference between B330-13-F and B330Q-13-F?

A: Both parts are electrically equivalent with identical core specifications. The B330Q-13-F includes automotive-grade qualification (AEC-Q101) and maintains the full operating temperature range of -55°C ~ 150°C. The B330-13-F operates to -55°C ~ 125°C. Select B330Q-13-F for automotive applications requiring AEC-Q101 certification.

Q: Are the Vishay SS33HE3_B/H and SS33HE3_B/I variants interchangeable?

A: Yes. Both Vishay variants are electrically identical with the same core specifications and both carry AEC-Q101 automotive qualification. The designations _B/H and _B/I represent different internal qualification or manufacturing batches but do not affect electrical performance or substitution compatibility.

Q: Why does SK33-TP have "Not For New Designs" status?

A: This designation indicates the manufacturer (Micro Commercial Co) does not recommend the SK33-TP for new product development. While electrically equivalent, use this part only for legacy system maintenance or existing production lines. For new designs, select from Active status alternatives.

Q: What packaging formats are available for substitutes?

A: B330-13-F is available in Cut Tape (CT) and Digi-Reel formats. B330Q-13-F, SK33-TP, SS33HE3_B/H, and SS33HE3_B/I are available in Tape & Reel (TR) format. SS33 is available in Bulk packaging. Select packaging based on production volume and assembly equipment requirements.

Q: Are there temperature range differences between substitutes?

A: Yes. B330-13-F operates to -55°C ~ 125°C, while B330Q-13-F, SK33-TP, SS33, SS33HE3_B/H, and SS33HE3_B/I all operate to -55°C ~ 150°C. The original B330CE-13 also operates to -55°C ~ 150°C. For applications requiring the full -55°C ~ 150°C range, select B330Q-13-F or the Vishay variants.

Q: What is the reverse leakage current difference between B330CE-13 and substitutes?

A: The B330CE-13 specifies 150 µA @ 30 V reverse leakage. All substitute parts specify 500 µA @ 30 V. This higher leakage in substitutes does not disqualify electrical equivalence but should be evaluated for low-power or high-impedance circuit applications where leakage current is critical.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. However, REACH compliance differs: B330-13-F is REACH Unaffected, while B330CE-13 is REACH Affected. Verify REACH requirements for your supply chain and regulatory jurisdiction.
