NP2600SCMCT3G Equivalent & Substitute Parts

Part Overview

The NP2600SCMCT3G is a 220V off-state, 400A peak pulse TVS thyristor manufactured by onsemi in DO-214AA (SMB) surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part functions as a transient voltage suppressor for circuit protection applications requiring high current handling capability at 220V nominal voltage levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NP2600SCMCT3G is determined by the following critical parameters:

• Voltage - Off State: 220V (primary voltage rating)
• Voltage - Breakover: 300V (triggering threshold)
• Current - Peak Pulse (8/20µs): 400A minimum (primary current specification)
• Package / Case: DO-214AA, SMB (mechanical and thermal compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Number of Elements: 1 (functional equivalence)

Substitute parts are classified into two categories:

Direct Substitutes: Parts meeting all critical parameters (220V off-state, 300V breakover, 400A peak pulse 8/20µs rating, DO-214AA package).

Similar Substitutes: Parts with 220V off-state voltage and DO-214AA package but with reduced peak pulse current ratings (250A or 150A) or alternative voltage ratings (200V). These require application-level current capacity verification.

Parameter Comparison

Engineering Selection Recommendations

Primary Direct Substitutes:

P2600SCLRP (Littelfuse Inc.) and P2600SCMCLRP (Littelfuse Inc.) are direct functional equivalents with identical voltage ratings (220V off-state, 300V breakover) and current specifications (400A peak pulse 8/20µs). Both are active products with RoHS3 compliance and unlimited moisture sensitivity rating. P2600SCLRP is preferred for applications requiring lower on-state voltage (4V) and higher capacitance (80pF). P2600SCMCLRP offers slightly higher on-state voltage (5V) with intermediate capacitance (45pF).

Secondary Substitutes for Reduced Current Applications:

TB2600M-13-F (Diodes Incorporated) maintains 220V off-state and 300V breakover voltage but reduces peak pulse current to 250A (8/20µs). This part is suitable for applications where 250A peak pulse capacity is sufficient. RoHS3 compliance is confirmed.

Lower Voltage Alternative:

SMTBJ200B (Littelfuse Inc.) operates at 200V off-state with 265V breakover voltage. Peak pulse current is 250A (8/20µs). This part is suitable only for applications designed for 200V nominal voltage protection and is RoHS non-compliant.

Reduced Current Alternatives:

SMTPA220 (STMicroelectronics) and TISP4C290H3BJR-S (Bourns Inc.) provide 220V off-state protection with significantly reduced peak pulse current ratings (150A and unspecified, respectively). These parts are suitable only for low-current transient suppression applications. Both are RoHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can P2600SCLRP directly replace NP2600SCMCT3G?

A: Yes. P2600SCLRP meets all critical electrical parameters: 220V off-state voltage, 300V breakover voltage, 400A peak pulse current (8/20µs), and DO-214AA package. The part is active and RoHS3 compliant. Capacitance difference (80pF vs. 33pF) must be evaluated for specific circuit timing requirements.

Q: What is the difference between P2600SCLRP and P2600SCMCLRP?

A: Both parts share identical voltage and current ratings. P2600SCLRP has 4V on-state voltage and 80pF capacitance. P2600SCMCLRP has 5V on-state voltage and 45pF capacitance. Selection depends on circuit requirements for on-state voltage drop and capacitive loading.

Q: Can TB2600M-13-F be used as a substitute?

A: TB2600M-13-F is a functional substitute only for applications where 250A peak pulse current (8/20µs) is acceptable. It maintains 220V off-state and 300V breakover voltage ratings. Applications requiring 400A peak pulse capacity cannot use this part.

Q: Is SMTBJ200B compatible with NP2600SCMCT3G?

A: SMTBJ200B is not a direct substitute. It operates at 200V off-state voltage (vs. 220V) and 265V breakover voltage (vs. 300V). Use only in applications specifically designed for 200V nominal voltage protection. RoHS compliance status differs (non-compliant).

Q: What packaging considerations apply to these substitutes?

A: All listed substitute parts use DO-214AA (SMB) surface mount package, identical to the NP2600SCMCT3G. No PCB layout or assembly process modifications are required for package compatibility.

Q: Which substitute offers the best compliance profile?

A: P2600SCLRP and P2600SCMCLRP (Littelfuse Inc.) both provide RoHS3 compliance and REACH unaffected status. SMTPA220 (STMicroelectronics) and TISP4C290H3BJR-S (Bourns Inc.) also provide RoHS3 compliance. SMTBJ200B is RoHS non-compliant.
