CD214L-T7.0ALF Equivalent & Substitute Parts

Part Overview

The CD214L-T7.0ALF 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 7V reverse standoff voltage with 12V clamping capability and 250A peak pulse current handling 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-T7.0ALF is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Clamping (Max) @ Ipp: 12V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional

Substitute parts are grouped into two categories based on peak pulse current capability:

Category A - Full Specification Match (250A Peak Pulse): Parts that maintain the original 250A peak pulse current and 3000W power dissipation, providing direct functional equivalence.

Category B - Reduced Current Rating (125A Peak Pulse): Parts that meet voltage and package requirements but operate at 125A peak pulse current and 1500W power dissipation. These are suitable for applications with lower transient energy requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Specification Match):

SMLJ7.0A (Bourns Inc.) and SMDJ7.0A (Alpha & Omega Semiconductor Inc.) are direct functional equivalents to the CD214L-T7.0ALF. Both maintain 250A peak pulse current, 3000W power dissipation, and identical voltage specifications. SMLJ7.0A is manufactured by the original equipment supplier and carries active product status with ROHS3 compliance. SMDJ7.0A provides an alternative source with equivalent electrical performance and ROHS3 compliance.

Secondary Substitutes (Reduced Current Rating):

SMCJ7.0A (MDD), SMCJ7.0A-TP (Micro Commercial Co), SMCJ7V0A (Fairchild Semiconductor), and TV15C7V0J-HF (Comchip Technology) are suitable for applications where peak pulse current requirements do not exceed 125A. All maintain the 7V reverse standoff and 12V clamping voltages. SMCJ7.0A-TP offers the widest operating temperature range (-55°C ~ 175°C). All secondary substitutes carry active product status and appropriate compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can SMCJ7.0A be used as a direct replacement for CD214L-T7.0ALF?

A: SMCJ7.0A is electrically compatible for voltage specifications but operates at 125A peak pulse current versus the original 250A. Use this substitute only if your application transient energy requirements do not exceed 1500W peak pulse power. For applications requiring full 250A capability, select SMLJ7.0A or SMDJ7.0A.

Q: What is the difference between SMLJ7.0A and SMDJ7.0A?

A: Both parts maintain identical electrical specifications (7V standoff, 12V clamping, 250A peak pulse, 3000W power). SMLJ7.0A is manufactured by Bourns Inc., the original supplier. SMDJ7.0A is manufactured by Alpha & Omega Semiconductor Inc. Selection depends on supplier availability and procurement preferences.

Q: Are all substitute parts available in the same packaging?

A: All listed substitutes use DO-214AB (SMC) surface-mount packaging, maintaining mechanical compatibility with the original CD214L-T7.0ALF footprint. Packaging formats vary (Tape & Reel or Bulk), but the component package remains consistent.

Q: Does operating temperature range affect substitution suitability?

A: Operating temperature ranges vary among substitutes. SMCJ7.0A-TP supports -55°C ~ 175°C, exceeding the original -55°C ~ 150°C specification. SMCJ7.0A operates at -50°C ~ 150°C. Select based on your application's thermal requirements. For standard -55°C ~ 150°C operation, all substitutes are suitable.

Q: Are all substitutes RoHS3 compliant?

A: All listed substitutes carry ROHS3 compliance certification, matching the original CD214L-T7.0ALF compliance status. This ensures compatibility with RoHS3-regulated applications and procurement requirements.
