CD214C-T130ALF Equivalent & Substitute Parts

Part Overview

The CD214C-T130ALF is a 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 130V reverse standoff voltage with 209V maximum clamping voltage and 7.2A peak pulse current capability in a DO-214AB (SMC) package. The component is classified as obsolete, necessitating identification of active equivalent and substitute parts that maintain electrical and mechanical compatibility for new designs or production continuity.

Substitute Part Grouping Explanation

Substitution of the CD214C-T130ALF is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Voltage - Reverse Standoff: 130V (±tolerance)
Voltage - Clamping (Max) @ Ipp: 209V
Package / Case: DO-214AB (SMC)
Mounting Type: Surface Mount
Type: Zener, Unidirectional (1 channel)

Direct Equivalents maintain identical electrical specifications (7.2A peak pulse current, 1500W peak pulse power) and are pin-for-pin compatible replacements.

Similar Substitutes share the core voltage and package specifications but differ in peak pulse current (14.4A to 24A) and peak pulse power (3000W to 5000W). These parts provide enhanced transient protection capability and are mechanically and electrically compatible for applications where higher surge handling is acceptable.

All substitute parts listed maintain DO-214AB (SMC) package compatibility, surface mount configuration, and the required voltage protection characteristics. Operating temperature ranges vary between -55°C to -65°C minimum and 150°C to 175°C maximum across the substitute options.

Engineering Selection Recommendations

Direct Replacement (Electrical Equivalence): SMCJ130A (Meritek) provides the closest direct replacement with 7.18A peak pulse current matching the original 7.2A specification and identical 1500W power rating. This part is active in production and ROHS3 compliant.

SMCJ130A-HR, SMCJ130A-HRA, and SMCJ130A-HRAT7 (all Littelfuse Inc.) are functionally equivalent with 7.2A peak pulse current and 1500W power. These variants feature extended operating temperature range to -65°C minimum and are active products with ROHS3 compliance.

SMCJ130A-TP (Micro Commercial Co) maintains 7.2A and 1500W specifications with extended upper temperature rating to 175°C, offering broader thermal operating range while remaining ROHS3 compliant.

Enhanced Protection Alternative: SMDJ130A (Alpha & Omega Semiconductor Inc.) provides 14.4A peak pulse current and 3000W power, doubling the transient handling capability while maintaining 130V standoff and 209V clamping voltages. This part is suitable for applications requiring higher surge protection margins.

5.0SMDJ130A (MDE Semiconductor Inc) and 5.0SMDJ130A-T7 (Littelfuse) offer maximum transient protection with 24A peak pulse current and 5000W power. The Littelfuse variant extends minimum operating temperature to -65°C. Both maintain full voltage compatibility and DO-214AB packaging.

All recommended substitutes are active products with ROHS3 compliance and MSL 1 rating, ensuring manufacturing continuity and environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can SMCJ130A directly replace CD214C-T130ALF? A: Yes. SMCJ130A maintains identical voltage specifications (130V standoff, 209V clamping), equivalent peak pulse current (7.18A vs 7.2A), matching 1500W power rating, and identical DO-214AB (SMC) package. Pin-for-pin substitution is valid.

Q: What is the difference between direct equivalents and similar substitutes? A: Direct equivalents (SMCJ130A, SMCJ130A-HR, SMCJ130A-HRAT7, SMCJ130A-TP) maintain the original 7.2A peak pulse current and 1500W power. Similar substitutes (SMDJ130A, 5.0SMDJ130A, 5.0SMDJ130A-T7) provide higher current and power ratings (14.4A to 24A, 3000W to 5000W) for enhanced transient protection. All share the same voltage protection characteristics and package.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original CD214C-T130ALF environmental specifications.

Q: Does operating temperature range affect substitution? A: Operating temperature ranges vary across substitutes. The original CD214C-T130ALF operates -55°C to 150°C. Littelfuse variants extend to -65°C minimum. SMCJ130A-TP extends to 175°C maximum. Selection depends on application thermal requirements; all listed parts are compatible for standard -55°C to 150°C applications.

Q: Can I use a higher power-rated substitute like 5.0SMDJ130A? A: Yes. Higher power-rated substitutes (SMDJ130A, 5.0SMDJ130A, 5.0SMDJ130A-T7) are electrically and mechanically compatible. They provide enhanced transient suppression capability without compromising circuit protection. Voltage specifications remain identical at 130V standoff and 209V clamping.

Q: What packaging options are available? A: All substitute parts use DO-214AB (SMC) surface mount package, identical to the original CD214C-T130ALF. Tape & Reel (TR) packaging is available for production quantities on most active variants.
