CD214L-T6.5ALF Equivalent & Substitute Parts

Part Overview

The CD214L-T6.5ALF is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 6.5V reverse standoff voltage with an 11.2V maximum clamping voltage and 267.9A peak pulse current capability in a DO-214AB (SMC) package. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD214L-T6.5ALF is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Breakdown (Min): 7.22V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional

Performance Parameters:

• Current - Peak Pulse (10/1000µs): 267.9A (direct equivalents) or 140A–133.9A (reduced performance alternatives)
• Power - Peak Pulse: 3000W (direct equivalents) or 1500W (reduced performance alternatives)

Substitute parts are grouped into two categories:

Direct Equivalents maintain identical electrical performance (267.9A peak pulse current, 3000W peak power) with the same voltage specifications and package. These parts are fully interchangeable without circuit redesign.

Similar Performance Alternatives maintain identical voltage specifications and package but feature reduced peak pulse current (140A–133.9A) and peak power (1500W). These parts are suitable only when circuit design margins permit lower transient current handling.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for Obsolescence Replacement):

SMLJ6.5A (Bourns Inc.), SMDJ6.5A-HR (Littelfuse Inc.), SMDJ6.5A-HRAT7 (Littelfuse Inc.), SMDJ6.5A (Alpha & Omega Semiconductor Inc.), SMDJ6.5A-HRA (Littelfuse Inc.), and SMLJ6.5A-TP (Micro Commercial Co) are direct functional equivalents. All maintain 267.9A peak pulse current, 3000W peak power, and identical voltage specifications. These parts are in active production status and carry ROHS3 compliance. Selection among these options depends on packaging availability (Tape & Reel vs. Bulk) and supplier inventory. SMLJ6.5A-TP offers extended operating temperature range to 175°C, providing additional thermal margin in high-temperature applications.

Similar Performance Alternatives (Reduced Transient Handling):

SMCJ6.5A (Taiwan Semiconductor Corporation), SMCJ6V5A (Fairchild Semiconductor), and TV15C6V5J-HF (Comchip Technology) maintain identical voltage specifications and package but feature reduced peak pulse current (140A–133.9A) and peak power (1500W). These parts are suitable only when circuit design analysis confirms that transient current requirements do not exceed 140A. All three are in active production and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can I use SMCJ6.5A or SMCJ6V5A as direct replacements for CD214L-T6.5ALF?

A: SMCJ6.5A and SMCJ6V5A maintain identical voltage specifications (6.5V reverse standoff, 11.2V clamping) and package (DO-214AB, SMC) but feature reduced peak pulse current (140A and 133.9A respectively versus 267.9A). These parts are suitable only if your circuit design analysis confirms that transient current requirements do not exceed 140A. For applications requiring full 267.9A handling capability, use direct equivalents such as SMLJ6.5A or SMDJ6.5A-HR.

Q: What is the difference between SMDJ6.5A-HR and SMDJ6.5A-HRAT7?

A: Both parts are manufactured by Littelfuse Inc. and maintain identical electrical specifications (6.5V reverse standoff, 11.2V clamping, 267.9A peak pulse, 3000W peak power) and package (DO-214AB, SMC). The primary difference is packaging format. SMDJ6.5A-HR and SMDJ6.5A-HRAT7 are both supplied in Tape & Reel format. Both are suitable direct replacements for CD214L-T6.5ALF.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not disqualify a part from substitution if voltage and current specifications match. SMLJ6.5A-TP operates from -55°C to 175°C, providing extended thermal capability compared to the original CD214L-T6.5ALF (-55°C to 150°C). SMDJ6.5A-HR and SMDJ6.5A-HRAT7 operate from -65°C to 150°C, providing extended low-temperature capability. These extended ranges represent design improvements and do not prevent substitution.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance certification, matching the original CD214L-T6.5ALF specification.

Q: What packaging formats are available for substitute parts?

A: Direct equivalents are available in Tape & Reel (TR) format (SMLJ6.5A, SMDJ6.5A-HR, SMDJ6.5A-HRAT7, SMDJ6.5A-HRA, SMLJ6.5A-TP, TV15C6V5J-HF) and Bulk format (SMCJ6V5A). SMDJ6.5A and SMCJ6.5A do not specify packaging format in available data. Verify packaging availability with your supplier before finalizing procurement.
