TSMBJ1007C Equivalent & Substitute Parts

Part Overview

The TSMBJ1007C is a 90V off-state transient voltage suppressor thyristor manufactured by Micro Commercial Co, housed in a DO-214AA (SMB) surface mount package. This component is designed to protect circuits from transient voltage spikes with a peak pulse current rating of 400A at 8/20µs. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TSMBJ1007C is determined by the following critical parameters:

• Voltage - Off State: Must be 90V
• Voltage - Breakover: Must be 130V or within acceptable circuit tolerance
• Current - Peak Pulse (8/20µs): Must be 400A or greater
• Package / Case: Must be DO-214AA (SMB) surface mount
• Current - Hold (Ih): Must be 150mA

Substitute parts are grouped into two categories:

Direct Equivalents (400A Peak Pulse Current): Parts meeting all critical parameters with 400A peak pulse current rating.

Functional Alternatives (Lower Peak Pulse Current): Parts with reduced peak pulse current ratings (150A to 300A) suitable for applications with lower transient current requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for TSMBJ1007C Replacement)

P1100SCLRP, P1100SCMCLRP, SMP100LC-90, and TB1100H-13-F are direct functional equivalents with 400A peak pulse current ratings matching the original specification. All are active products with ROHS3 compliance, ensuring long-term availability and regulatory alignment. P1100SCLRP and P1100SCMCLRP are Littelfuse SIDACtor® series components with established supply chains. TB1100H-13-F from Diodes Incorporated offers equivalent performance with identical capacitance to the original part. SMP100LC-90 from STMicroelectronics provides TRISIL™ series protection with a slightly lower breakover voltage (125V vs. 130V).

Functional Alternatives (Lower Current Applications)

TISP4115H3BJR-S from Bourns Inc. provides 300A peak pulse current, suitable for applications with reduced transient current requirements. P1100SALRP and P1100SBLRP offer 150A and 250A ratings respectively, for lower-stress circuit protection scenarios. These alternatives maintain the 90V off-state voltage and 150mA hold current specifications.

All substitute parts are available in active production status with ROHS3 compliance, except TISP4115H3BJR-S which carries REACH Affected status.

Frequently Asked Questions (FAQ)

Q: Can P1100SCLRP directly replace TSMBJ1007C in existing designs?

A: Yes. P1100SCLRP matches all critical electrical parameters: 90V off-state voltage, 130V breakover voltage, 400A peak pulse current (8/20µs), and 150mA hold current. Both use DO-214AA (SMB) packaging. The 5pF capacitance difference (115pF vs. 120pF) is within acceptable tolerance for transient suppression applications.

Q: What is the difference between the 400A and 300A rated parts?

A: Peak pulse current rating determines the maximum transient current the device can suppress. The 400A-rated parts (P1100SCLRP, P1100SCMCLRP, SMP100LC-90, TB1100H-13-F) handle higher transient events. The 300A-rated TISP4115H3BJR-S is suitable for lower-stress applications. Selection depends on the actual transient current magnitude in your circuit.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original TSMBJ1007C is RoHS non-compliant, making the substitutes necessary for new designs meeting RoHS requirements.

Q: Does the on-state voltage variation affect circuit performance?

A: On-state voltage ranges from 3V to 5V across the substitute options. This parameter affects voltage clamping during transient events. For critical applications, verify that the specific on-state voltage of your selected substitute is compatible with your circuit's transient suppression requirements.

Q: What packaging options are available?

A: All listed parts use DO-214AA (SMB) surface mount packaging. Packaging variations include Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® options, which affect procurement and assembly processes but not electrical performance.

Q: Is SMP100LC-90 suitable as a replacement despite the 125V breakover voltage?

A: SMP100LC-90 has a 125V breakover voltage compared to the original 130V specification. This 5V difference may be acceptable depending on circuit tolerance requirements. Verify that the lower breakover threshold does not cause premature triggering in your specific application.
