CD214L-T8.0CALF Equivalent & Substitute Parts

Part Overview

The CD214L-T8.0CALF is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., rated for 8V reverse standoff voltage with a 13.6V maximum clamping voltage. This surface mount component in DO-214AB (SMC) package is designed for general-purpose transient protection applications. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214L-T8.0CALF is determined by the following critical parameters:

• Voltage - Reverse Standoff: 8V (±tolerance)
• Voltage - Clamping (Max) @ Ipp: 13.6V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional

Substitute parts are grouped into two categories:

Direct Substitutes (Electrical & Mechanical Equivalence): Parts with identical voltage ratings, clamping specifications, and peak pulse current of 220.6A, maintaining full functional equivalence.

Similar Substitutes (Voltage & Package Equivalence with Reduced Current Rating): Parts with matching voltage specifications and package type but with reduced peak pulse current (110.3A to 115A) and lower power dissipation (1500W). These maintain voltage protection characteristics but with lower transient current handling capacity.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Electrical Equivalence):

SMLJ8.0CA (Bourns Inc.), SMDJ8.0CA-HR (Littelfuse Inc.), SMDJ8.0CA-HRA (Littelfuse Inc.), SMDJ8.0CA-HRAT7 (Littelfuse Inc.), and SMDJ8.0CA (Alpha & Omega Semiconductor Inc.) are direct functional equivalents with identical voltage ratings, peak pulse current of 220.6A, and 3000W power dissipation. All are active products with ROHS3 compliance. The Littelfuse variants offer extended operating temperature range to -65°C. Selection among these should be based on availability, packaging format (Tape & Reel vs. Bulk), and supply chain preference.

Secondary Substitutes (Voltage Equivalence with Reduced Current Capacity):

SMCJ8.0CA (Taiwan Semiconductor Corporation), SMCJ8.0CA-TP (Micro Commercial Co), and SMCJ8V0CA (Fairchild Semiconductor) maintain identical voltage protection characteristics but with reduced peak pulse current ratings (110.3A to 115A) and 1500W power dissipation. These are suitable for applications where transient current levels do not exceed their rated specifications. SMCJ8.0CA-TP offers the widest operating temperature range (-55°C to 175°C).

All substitute parts maintain DO-214AB (SMC) surface mount package compatibility and ROHS3 compliance status.

Frequently Asked Questions (FAQ)

Q: Can SMCJ8.0CA be used as a direct replacement for CD214L-T8.0CALF?

A: SMCJ8.0CA maintains voltage protection equivalence (8V standoff, 13.6V clamping) and package compatibility but has reduced peak pulse current (115A vs. 220.6A) and power dissipation (1500W vs. 3000W). It is suitable only if the application's transient current does not exceed 115A.

Q: What is the difference between SMDJ8.0CA-HR, SMDJ8.0CA-HRA, and SMDJ8.0CA-HRAT7?

A: All three are Littelfuse products with identical electrical specifications (8V standoff, 13.6V clamping, 220.6A peak pulse, 3000W power). The suffix designations indicate different packaging or date code variants. Selection should be based on availability and supply chain requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. The original CD214L-T8.0CALF is also ROHS3 compliant.

Q: Which substitute offers the best temperature performance?

A: SMCJ8.0CA-TP (Micro Commercial Co) provides the widest operating temperature range at -55°C to 175°C. The Littelfuse variants (SMDJ8.0CA-HR, SMDJ8.0CA-HRA, SMDJ8.0CA-HRAT7) extend the lower temperature limit to -65°C while maintaining 150°C upper limit.

Q: Can I use a substitute with lower peak pulse current if my circuit only experiences occasional transients?

A: Application-specific transient analysis is required. If peak transient current is confirmed to remain below the substitute part's rating, lower-current variants may be acceptable. However, this determination must be made through circuit analysis, not assumption.

Q: What packaging formats are available for the direct substitutes?

A: SMLJ8.0CA is available in Tape & Reel format. Littelfuse variants (SMDJ8.0CA-HR, SMDJ8.0CA-HRA, SMDJ8.0CA-HRAT7) are supplied in Tape & Reel. SMDJ8.0CA (Alpha & Omega) is available in Tape & Reel. Packaging format should be verified with the supplier for specific procurement requirements.
