CD214A-T130ALF Equivalent & Substitute Parts

Part Overview

The CD214A-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 operates with a 130V reverse standoff voltage and 209V maximum clamping voltage, delivering 1.9A peak pulse current in a DO-214AC (SMA) package. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD214A-T130ALF is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 130V
• Voltage - Clamping (Max) @ Ipp: 209V
• Current - Peak Pulse (10/1000µs): 1.9A ± tolerance
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC (SMA)
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional

Direct Equivalents maintain all critical electrical parameters within specified tolerances and identical package configuration. These parts are functionally interchangeable without circuit modification.

Similar Substitutes maintain the core voltage and power ratings but may have minor variations in peak pulse current (within acceptable operating margins) or extended operating temperature ranges. These parts are suitable for applications where the specified parameters remain within design tolerances.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended First Choice):

SMAJ130A (Meritek) and TV04A131J-G (Comchip Technology) are direct functional equivalents to the CD214A-T130ALF. Both maintain identical reverse standoff voltage (130V), clamping voltage (209V), and peak pulse current (1.9A–1.91A) specifications. All three parts share the DO-214AC (SMA) package, ROHS3 compliance, and MSL 1 rating. SMAJ130A-TP (Micro Commercial Co) provides an additional option with extended operating temperature range (-55°C to 175°C), offering enhanced thermal performance for applications requiring higher junction temperatures.

Similar Substitutes (Alternative Selection):

SMAJ150A-M3/61 and SMAJ150A-M3/5A (Vishay General Semiconductor - Diodes Division) represent similar substitutes with higher voltage ratings (150V reverse standoff, 243V clamping). These parts are suitable only when circuit design permits higher voltage operation. Peak pulse current is reduced to 1.2A and power dissipation to 300W, requiring verification that application requirements do not exceed these limits. Both maintain ROHS3 compliance and MSL 1 rating.

Selection Basis:

All substitute parts are active products with confirmed inventory availability, ensuring supply chain continuity. Selection should prioritize direct equivalents (SMAJ130A, SMAJ130A-TP, TV04A131J-G) for drop-in replacement without circuit redesign. Similar substitutes (SMAJ150A series) require design review to confirm compatibility with higher voltage and lower current specifications.

Frequently Asked Questions (FAQ)

Q: Can SMAJ130A directly replace CD214A-T130ALF without circuit modification?

A: Yes. SMAJ130A maintains identical electrical specifications: 130V reverse standoff, 209V clamping voltage, 1.9A peak pulse current, and 400W power dissipation. The DO-214AC (SMA) package is mechanically identical. No circuit modification is required.

Q: What is the difference between SMAJ130A and SMAJ130A-TP?

A: Both parts are electrically identical with matching voltage and current ratings. SMAJ130A-TP offers an extended operating temperature range (-55°C to 175°C) compared to the standard range (-55°C to 150°C), providing thermal margin for high-temperature applications.

Q: Can SMAJ150A-M3/61 be used as a substitute?

A: SMAJ150A-M3/61 is a similar substitute with higher voltage ratings (150V standoff, 243V clamping) but reduced peak pulse current (1.2A vs. 1.9A) and power dissipation (300W vs. 400W). Substitution is valid only if circuit design permits higher voltage operation and does not require the full 1.9A current capability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (SMAJ130A, SMAJ130A-TP, TV04A131J-G, SMAJ150A-M3/61, SMAJ150A-M3/5A) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original CD214A-T130ALF specifications.

Q: What is the primary reason for substitution?

A: The CD214A-T130ALF is obsolete. Direct equivalents from active manufacturers (Meritek, Micro Commercial Co, Comchip Technology) ensure continued design support and production availability.

Q: Do all substitute parts use the same DO-214AC (SMA) package?

A: Yes. All substitute parts listed use the DO-214AC (SMA) surface-mount package, ensuring mechanical and footprint compatibility with existing PCB designs.
