Critical Matching Parameters:

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

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Choices):

SMLJ130A (Bourns Inc.) and SMDJ130A (Alpha & Omega Semiconductor Inc.) are direct electrical and mechanical equivalents to the CD214L-T130ALF. Both maintain identical voltage specifications (130V standoff, 209V clamping), current ratings (14.4A peak pulse), and power dissipation (3000W). Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). SMLJ130A is supplied in Tape & Reel packaging with 11,914 units in stock. SMDJ130A is supplied in Tape & Reel packaging with 30,400 units in stock, providing superior availability.

Enhanced Performance Alternatives:

5.0SMDJ130A (MDE Semiconductor Inc.) and 5.0SMDJ130A-T7 (Littelfuse) exceed the original specifications with 24A peak pulse current and 5000W power dissipation while maintaining identical voltage parameters. These parts are suitable for applications requiring higher transient energy absorption. 5.0SMDJ130A-T7 extends the operating temperature range to -65°C, providing enhanced low-temperature performance.

Lower Power Alternatives:

SMCJ130A variants (Meritek, Littelfuse) provide reduced peak pulse current (7.2A) and power dissipation (1500W) while maintaining voltage compatibility. These parts are appropriate for applications with lower transient energy requirements. Littelfuse variants (SMCJ130A-HR, SMCJ130A-HRA, SMCJ130A-HRAT7) extend operating temperature to -65°C. SMCJ130A-TP (Micro Commercial Co) offers the widest operating temperature range (-55°C to 175°C).

Compliance Status:

All recommended substitutes are ROHS3 compliant with MSL 1 rating. SMLJ130A and SMDJ130A maintain REACH Affected status matching the original part. Alternative manufacturers' parts are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can SMLJ130A directly replace CD214L-T130ALF in existing designs?

A: Yes. SMLJ130A is a direct equivalent with identical electrical specifications (130V standoff, 209V clamping, 14.4A peak pulse, 3000W power) and package (DO-214AB SMC). Both are Bourns products with matching compliance certifications.

Q: What is the difference between SMDJ130A and 5.0SMDJ130A?

A: Both maintain the same voltage specifications (130V standoff, 209V clamping). SMDJ130A provides 14.4A peak pulse and 3000W power dissipation. 5.0SMDJ130A provides enhanced performance with 24A peak pulse and 5000W power dissipation. Selection depends on transient energy requirements in the application.

Q: Are SMCJ130A variants suitable replacements?

A: SMCJ130A variants are mechanically compatible (DO-214AB SMC package) and electrically compatible for voltage specifications (130V standoff, 209V clamping). However, they provide reduced peak pulse current (7.2A) and power dissipation (1500W) compared to the original 14.4A and 3000W. Use only if application transient energy requirements are lower.

Q: What is the significance of the -T7 suffix in 5.0SMDJ130A-T7?

A: The -T7 suffix indicates Tape & Reel packaging format. This part is functionally identical to 5.0SMDJ130A but supplied in automated handling packaging suitable for high-volume production.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Compliance certifications are equivalent to the original CD214L-T130ALF.

Q: Which substitute offers the best availability?

A: SMDJ130A (Alpha & Omega Semiconductor Inc.) provides the highest inventory with 30,400 units in stock, followed by SMLJ130A (Bourns Inc.) with 11,914 units.

Q: Can I use a substitute with higher power rating in a design rated for 3000W?

A: Yes. Parts with higher power ratings (5.0SMDJ130A at 5000W) are backward compatible for applications designed for lower power dissipation. The component will operate within its design envelope with margin.

Q: What is the operating temperature consideration for low-temperature applications?

A: The original CD214L-T130ALF operates from -55°C to 150°C. Littelfuse variants (SMCJ130A-HR, SMCJ130A-HRA, SMCJ130A-HRAT7) and 5.0SMDJ130A-T7 extend the lower limit to -65°C for enhanced cold-temperature performance.
