TVB200SC-L Equivalent & Substitute Parts

Part Overview

The TVB200SC-L is a 200V off-state, 400A peak pulse transient voltage suppressor thyristor manufactured by Littelfuse Inc. in the DO-214AA (SMB) package. This component is classified as obsolete, which necessitates identification of active alternative parts that maintain electrical and mechanical compatibility for new designs or production continuity.

Substitute Part Grouping Explanation

Substitution of the TVB200SC-L is determined by the following critical parameters:

Off-State Voltage: Must match or exceed 200V to maintain blocking capability
Peak Pulse Current (8/20µs): Must support 400A minimum to handle transient events
Package / Case: Must be DO-214AA (SMB) for mechanical and thermal compatibility
Mounting Type: Must be surface mount for PCB integration
Number of Elements: Single element configuration preferred for direct replacement

Substitute parts are grouped into two categories based on voltage rating and current handling:

Category A - Direct Voltage Match (200V Off-State): Parts with 200V off-state voltage and 400A peak pulse current capability provide direct electrical equivalence.

Category B - Elevated Voltage (220V Off-State): Parts with 220V off-state voltage offer enhanced overvoltage margin while maintaining 400A peak pulse current capability. These are suitable where slightly higher breakover voltage is acceptable.

Engineering Selection Recommendations

Primary Substitute - Direct Replacement:

SMP100LC-200 (STMicroelectronics) is the optimal direct substitute. It matches the 200V off-state voltage and 400A peak pulse current specification of the TVB200SC-L. Both components are ROHS3 compliant and housed in DO-214AA packages. The SMP100LC-200 is actively manufactured with 17,590 units in stock, ensuring supply continuity.

Secondary Substitutes - Elevated Voltage Rating:

P2600SCLRP (Littelfuse Inc.) provides 220V off-state voltage with 400A peak pulse current capability. This part is actively produced and ROHS3 compliant. The elevated voltage rating provides additional overvoltage protection margin. Current inventory is 7,712 units.

P2600SBLRP (Littelfuse Inc.) offers 220V off-state voltage with 250A peak pulse current. This part is suitable for applications where 250A peak pulse current is sufficient. It is actively manufactured with 3,000 units available.

Alternative Substitutes - Reduced Current Rating:

P2600SALRP (Littelfuse Inc.) and P2602SALRP (Littelfuse Inc.) both provide 220V off-state voltage with 150A peak pulse current. These parts are appropriate for lower transient current applications. Both are ROHS3 compliant and actively produced.

Not Recommended:

SMTBJ200B is not recommended despite matching the 200V off-state voltage. This part is RoHS non-compliant and provides only 250A peak pulse current, which is insufficient for the 400A requirement of the original TVB200SC-L.

K2400SRP and K2500SRP are SIDAC/Diac thyristors with peak output current of only 1A. These parts are not suitable for transient voltage suppression applications requiring 400A peak pulse current.

Frequently Asked Questions (FAQ)

Q: Can SMP100LC-200 be used as a direct replacement for TVB200SC-L?

A: Yes. The SMP100LC-200 matches the critical electrical parameters: 200V off-state voltage, 400A peak pulse current (8/20µs), and DO-214AA package. Both are ROHS3 compliant. The SMP100LC-200 is actively manufactured, addressing the obsolescence of the TVB200SC-L.

Q: What is the difference between P2600SCLRP and TVB200SC-L?

A: The P2600SCLRP has a 220V off-state voltage compared to the TVB200SC-L's 200V. Both support 400A peak pulse current and use the DO-214AA package. The higher voltage rating of the P2600SCLRP provides enhanced overvoltage margin. The P2600SCLRP is actively produced, whereas the TVB200SC-L is obsolete.

Q: Are the P2602 series parts (TwinChip™) compatible with TVB200SC-L?

A: The P2602SBLRP and P2602SALRP contain two elements versus the single element in TVB200SC-L. While they maintain the DO-214AA package and 220V off-state voltage, the dual-element configuration and reduced hold current (120mA versus 175mA) represent a different design topology. These parts are suitable only if the application circuit is designed for dual-element thyristors.

Q: Why is SMTBJ200B not recommended as a substitute?

A: SMTBJ200B is RoHS non-compliant and provides only 250A peak pulse current, which is insufficient for the 400A requirement of the TVB200SC-L. Additionally, it is not listed as an approved substitute in the original part documentation.

Q: Can K2400SRP or K2500SRP replace TVB200SC-L?

A: No. These are SIDAC/Diac thyristors with peak output current of 1A, designed for gate triggering applications. They are not suitable for transient voltage suppression requiring 400A peak pulse current handling.

Q: What packaging options are available for substitute parts?

A: All recommended substitute parts use the DO-214AA (SMB) surface mount package, maintaining mechanical and thermal compatibility with the original TVB200SC-L. Packaging formats vary between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) options depending on the specific part number.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitutes except SMTBJ200B are ROHS3 compliant. For applications requiring RoHS compliance, select from SMP100LC-200, P2600SCLRP, P2600SBLRP, P2600SALRP, P2602SBLRP, or P2602SALRP.
