Equivalent & Substitute Parts for CD214A-B340LLF

Part Overview

The Bourns Inc. CD214A-B340LLF is a Schottky diode designed for surface mount applications, contained in a DO-214AC (SMA) package. With a maximum DC reverse voltage of 40 V, an average rectified current of 3A, and a forward voltage of 450 mV at 3 A, it is suitable for fast recovery applications due to its recovery time parameters. The product is obsolete, making it necessary to identify alternative models with comparable electrical and mechanical characteristics for both design continuity and maintenance support.

Engineering Selection Recommendations

All substitute parts satisfy the RoHS3 compliance requirement and maintain an MSL of 1 (Unlimited). The substitute parts also fulfill the surface mount mounting criterion and offer mechanical compatibility in the DO-214AC (SMA) or similar surface-mount packages. Selection may also consider REACH status where relevant to the application context. Each listed substitute remains active or is designated as not for new designs as indicated.

Frequently Asked Questions (FAQ)

Q: What parameters are critical for selecting a substitute for CD214A-B340LLF?
A: The essential parameters are Schottky diode technology, maximum DC reverse voltage (Vr) of 40 V, average rectified current (Io) of 3A, maximum forward voltage (Vf) at 3 A, fast recovery speed (≤500ns), reverse leakage current, and compatibility with the surface mount DO-214AC (SMA) package. Compliance status such as RoHS3 and MSL 1 are additional requirements.

Q: Are all substitute parts supplied in the same package as CD214A-B340LLF?
A: Most substitutes are provided in the DO-214AC (SMA) or functionally similar surface-mount outlines, ensuring mechanical and assembly compatibility.

Q: How important is RoHS3 and MSL compliance in substitute selection?
A: RoHS3 compliance and an unlimited MSL (MSL 1) align with regulatory and manufacturing requirements for many applications. All listed substitutes meet these standards.

Q: Is there any variance in operating temperature ratings among substitutes?
A: Operating temperature ratings among substitutes may vary; ensure the substitute's temperature range meets the application's environmental requirements as specified in the provided data.

Q: Can a substitute with a higher forward voltage (Vf) be used?
A: Substitute parts are listed with their maximum forward voltage at the rated current. Selection is based strictly on the provided parameter data for direct equivalency.

Q: What should be considered regarding reverse leakage current?
A: Substitute diodes should not exceed the specified reverse leakage current at the rated reverse voltage for the main part unless explicitly stated in the selection criteria. This ensures electrical compatibility within expected circuit tolerances.
