CD214L-T6.0ALF Equivalent & Substitute Parts

Part Overview

The CD214L-T6.0ALF is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection applications. This component features a 6V reverse standoff voltage with a 10.3V maximum clamping voltage and 291.3A peak pulse current capability in a surface-mount DO-214AB (SMC) package. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214L-T6.0ALF is determined by the following critical parameters: voltage rating (6V reverse standoff, 6.67V minimum breakdown, 10.3V maximum clamping), unidirectional channel configuration (1 channel), package type (DO-214AB/SMC surface mount), and diode type (Zener). Parts meeting these specifications are classified into two substitution categories:

Direct Equivalents: Parts with identical electrical performance across all key parameters, including peak pulse current (291.3A) and peak pulse power (3000W).

Similar Substitutes: Parts with matching voltage ratings, package, and mounting type but with reduced peak pulse current and power dissipation capabilities (145.6A to 152A, 1500W to 1.5kW).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Full Replacement): SMLJ6.0A and SMDJ6.0A maintain identical electrical specifications to the CD214L-T6.0ALF, including 291.3A peak pulse current and 3000W power dissipation. Both parts are active products with ROHS3 compliance. SMLJ6.0A is manufactured by Bourns Inc., the original manufacturer, and is available in Tape & Reel packaging. SMDJ6.0A is manufactured by Alpha & Omega Semiconductor Inc. and is available in Tape & Reel packaging.

Similar Substitutes (Reduced Performance): SMCJ6.0A and SMCJ6V0A are active products with matching voltage ratings and package specifications but with reduced peak pulse current (152A and 145.6A respectively) and power dissipation (1500W). These parts are suitable for applications where peak pulse requirements do not exceed their specified ratings. SMCJ6.0A is manufactured by Taiwan Semiconductor Corporation. SMCJ6V0A is manufactured by Fairchild Semiconductor and is available in Bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can SMLJ6.0A directly replace CD214L-T6.0ALF? A: Yes. SMLJ6.0A is a direct equivalent with identical voltage ratings (6V reverse standoff, 10.3V clamping), peak pulse current (291.3A), and power dissipation (3000W). Both are Zener-type unidirectional TVS diodes in DO-214AB/SMC packages. SMLJ6.0A is an active product manufactured by Bourns Inc.

Q: What is the difference between direct equivalents and similar substitutes? A: Direct equivalents (SMLJ6.0A, SMDJ6.0A) maintain 291.3A peak pulse current and 3000W power dissipation. Similar substitutes (SMCJ6.0A, SMCJ6V0A) have reduced peak pulse current (145.6A to 152A) and power dissipation (1500W). Selection depends on application peak pulse requirements.

Q: Are all substitute parts RoHS compliant? A: SMLJ6.0A, SMDJ6.0A, SMCJ6.0A, and SMCJ6V0A are all ROHS3 compliant. Compliance certifications are documented for each active product.

Q: Does packaging affect substitution compatibility? A: All substitute parts use the same DO-214AB (SMC) surface-mount package as the CD214L-T6.0ALF. Packaging format (Tape & Reel, Bulk) affects procurement and handling but not electrical or mechanical compatibility.

Q: Which substitute offers the best availability? A: SMCJ6V0A has the highest inventory (43,029 pcs), followed by SMCJ6.0A (26,213 pcs). SMLJ6.0A has 9,170 pcs available. Inventory levels are subject to change.
