NP2600SAMCT3G Equivalent & Substitute Parts

Part Overview

The NP2600SAMCT3G is a 220V off-state thyristor TVS (Transient Voltage Suppressor) in DO-214AA/SMB packaging manufactured by onsemi. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part delivers 150A peak pulse current (8/20µs) with a 300V breakover voltage, designed for transient voltage protection in surface-mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NP2600SAMCT3G is determined by the following critical parameters:

• Voltage - Off State: Must be 220V
• Voltage - Breakover: Must be 300V (±tolerance)
• Package / Case: Must be DO-214AA, SMB
• Mounting Type: Must be Surface Mount
• Current - Peak Pulse (8/20µs): Acceptable range 150A to 400A
• Current - Hold (Ih): Must be 150mA

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

Category A - Direct Equivalents (150A rating): Parts with 150A peak pulse current matching the original specification exactly.

Category B - Higher Current Capability (250A-400A rating): Parts with enhanced peak pulse current ratings, suitable for applications requiring additional transient protection margin while maintaining identical voltage and hold current specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Direct Equivalent:

SMTPA220 (STMicroelectronics) is the recommended direct equivalent. It maintains 150A peak pulse current, 220V off-state voltage, and identical hold current. The part is RoHS3 compliant and carries active product status, ensuring long-term availability and supply chain stability. Breakover voltage of 293V is within acceptable tolerance of the original 300V specification.

Alternative Substitutes - Enhanced Current Capability:

TB2600L-13-F (Diodes Incorporated) provides an exact match at 150A peak pulse current with active status and RoHS3 compliance. This part is suitable for direct replacement in existing designs.

TB2600M-13-F and TB2600H-13-F (Diodes Incorporated) offer increased peak pulse current ratings of 250A and 400A respectively, both with active status and RoHS3 compliance. These parts are appropriate for applications requiring additional transient protection margin while maintaining voltage and hold current specifications.

P2600SCMCLRP (Littelfuse Inc., SIDACtor® series) delivers 400A peak pulse current with active status and RoHS3 compliance. This part is suitable for high-current transient protection applications.

Not Recommended:

SMTBJ200B (Littelfuse Inc.) operates at 200V off-state voltage and 265V breakover voltage, which deviates from the 220V/300V specification of the original part. This part is RoHS non-compliant and is not suitable for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can SMTPA220 be used as a direct replacement for NP2600SAMCT3G?

A: Yes. SMTPA220 maintains the critical electrical parameters: 220V off-state voltage, 150A peak pulse current (8/20µs), 150mA hold current, and identical DO-214AA/SMB packaging. The 293V breakover voltage is within acceptable tolerance of the original 300V specification.

Q: What is the difference between the 150A, 250A, and 400A rated parts?

A: Peak pulse current rating determines the maximum transient current the part can suppress. The 150A parts (SMTPA220, TB2600L-13-F) match the original specification. The 250A part (TB2600M-13-F) and 400A parts (TB2600H-13-F, P2600SCMCLRP) provide enhanced protection for applications with higher transient energy. All maintain identical 220V off-state voltage and 150mA hold current.

Q: Are all substitute parts RoHS compliant?

A: Most active substitutes are RoHS3 compliant. SMTBJ200B is RoHS non-compliant and is not recommended. Verify RoHS compliance requirements for your specific application before selection.

Q: Why is SMTBJ200B not recommended?

A: SMTBJ200B operates at 200V off-state voltage and 265V breakover voltage, which do not meet the 220V/300V specification of the original part. Additionally, it is RoHS non-compliant. This part is not suitable for direct substitution.

Q: Can I use a higher current-rated part (250A or 400A) in place of the 150A original?

A: Yes, provided all other electrical parameters match: 220V off-state voltage, 300V breakover voltage, 150mA hold current, and DO-214AA/SMB packaging. Higher current ratings provide additional transient protection margin and are electrically compatible with the original circuit design.

Q: What packaging options are available for these substitutes?

A: All substitute parts use DO-214AA/SMB surface-mount packaging, identical to the original NP2600SAMCT3G. Packaging compatibility is maintained across all recommended substitutes.

Q: How do I verify compatibility before ordering?

A: Confirm that the substitute part meets these parameters: 220V off-state voltage, 300V breakover voltage (±tolerance), 150mA hold current, DO-214AA/SMB package, and surface-mount mounting type. Cross-reference the datasheet for your specific application requirements.
