CD214C-T8.0ALF Equivalent & Substitute Parts

Part Overview

The CD214C-T8.0ALF is an 8V Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This unidirectional Zener diode features a 13.6V maximum clamping voltage and 110.3A peak pulse current capability within a 1500W power dissipation envelope. The component is packaged in DO-214AB (SMC) format for surface-mount assembly.

The CD214C-T8.0ALF is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for the CD214C-T8.0ALF is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage - Reverse Standoff: 8V
Voltage - Clamping (Max) @ Ipp: 13.6V
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
Unidirectional Channels: 1
Type: Zener

Allowable Variation Parameters:

Current - Peak Pulse (10/1000µs): 110.3A minimum (higher values acceptable for increased transient protection margin)
Power - Peak Pulse: 1500W minimum (higher values acceptable)
Operating Temperature Range: -55°C minimum, 150°C maximum (extended ranges acceptable)
RoHS Status: ROHS3 Compliant required

Substitute parts are grouped into two categories:

Direct Equivalents (1500W, 110.3A class): Parts matching the exact power and current specifications of the original component.

Enhanced Substitutes (3000W, 220.6A class): Parts with doubled power dissipation and current ratings, maintaining identical voltage parameters and package format. These provide superior transient protection capability within the same physical footprint.

Engineering Selection Recommendations

Direct Equivalent Selection (1500W Class):

SMCJ8.0A (Taiwan Semiconductor Corporation) is the primary direct equivalent. This part maintains identical electrical specifications and operating temperature range to the original CD214C-T8.0ALF while offering active product status and high inventory availability (9270 units). ROHS3 compliance and MSL 1 rating are confirmed.

SMCJ8.0A-TP (Micro Commercial Co) provides an alternative direct equivalent with extended upper operating temperature to 175°C, suitable for applications requiring elevated thermal performance. Tape & Reel packaging is standard.

SMCJ8.0A-HR, SMCJ8.0A-HRA, and SMCJ8.0A-HRAT7 (Littelfuse Inc.) are direct equivalents with extended lower operating temperature to -65°C. These variants are appropriate for applications requiring enhanced cold-temperature performance. All three maintain identical electrical specifications and are available in Tape & Reel packaging.

SMCJ8V0A (Fairchild Semiconductor) is a direct equivalent available in bulk packaging. Operating temperature range is not specified in available documentation.

Enhanced Substitute Selection (3000W Class):

SMDJ8.0A (Alpha & Omega Semiconductor Inc.) and SMDJ8.0A-HR, SMDJ8.0A-HRA (Littelfuse Inc.) provide doubled power dissipation (3000W) and peak pulse current (220.6A) while maintaining identical voltage parameters and DO-214AB package format. These parts are suitable for applications where increased transient energy absorption is required without circuit board redesign. All variants are ROHS3 compliant and available in Tape & Reel packaging.

Compliance Verification:

All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings where specified. REACH compliance status varies by manufacturer; verification against specific supply chain requirements is necessary.

Frequently Asked Questions (FAQ)

Q: Can SMDJ8.0A series parts (3000W) be used as direct replacements for CD214C-T8.0ALF (1500W)?

A: Yes. SMDJ8.0A series parts maintain identical voltage specifications (8V standoff, 13.6V clamping) and package format (DO-214AB, SMC). The doubled power rating and peak pulse current provide enhanced transient protection capability. No circuit modifications are required; the parts are pin-compatible and footprint-compatible.

Q: What is the difference between SMCJ8.0A-HR, SMCJ8.0A-HRA, and SMCJ8.0A-HRAT7?

A: All three parts are manufactured by Littelfuse Inc. and share identical electrical specifications. The designations reflect internal Littelfuse product line variants. Selection among these three should be based on supplier availability and packaging requirements (all are supplied in Tape & Reel format).

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not disqualify a part from substitution if the specified range meets or exceeds the original design requirements. Extended ranges (such as -65°C lower limit or 175°C upper limit) are acceptable enhancements. If the application operates within -55°C to 150°C, all listed substitutes are suitable.

Q: Are there packaging differences between substitute parts?

A: All substitute parts use DO-214AB (SMC) package format, ensuring identical PCB footprint and assembly compatibility. Packaging variants (Tape & Reel vs. Bulk) affect supply and handling but do not impact electrical or mechanical compatibility.

Q: What is the significance of the -TP, -HR, and -HRA suffixes in part numbers?

A: These suffixes denote manufacturer-specific product line designations and packaging configurations. -TP indicates Tape & Reel packaging from Micro Commercial Co. -HR and -HRA indicate Littelfuse high-reliability variants supplied in Tape & Reel format. Electrical specifications remain constant across these variants.

Q: Is SMCJ8V0A suitable for new designs if operating temperature is not specified?

A: SMCJ8V0A maintains all critical electrical parameters (8V standoff, 13.6V clamping, 110.3A peak pulse, 1500W power) and DO-214AB package compatibility. However, the absence of specified operating temperature range in available documentation requires clarification with the supplier before design implementation.
