TSMBJ1010C Equivalent & Substitute Parts

Part Overview

The TSMBJ1010C is a 140V off-state, 400A peak pulse transient voltage suppressor thyristor in DO-214AA (SMB) surface mount package manufactured by Micro Commercial Co. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates with a 180V breakover voltage and 5V on-state voltage, designed for transient suppression applications requiring high peak pulse current handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSMBJ1010C is determined by the following critical parameters:

• Voltage - Off State: 140V (exact match required)
• Voltage - Breakover: 180V ±5V tolerance acceptable
• Current - Peak Pulse (8/20µs): 400A minimum
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Number of Elements: 1 (exact match required)

All qualified substitutes maintain identical off-state voltage, package configuration, and mounting type. Variations in on-state voltage, capacitance, and breakover voltage within specified ranges do not affect functional compatibility in transient suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Electrical Equivalence):

P1500SCMCLRP (Littelfuse Inc.) and TB1500H-13-F (Diodes Incorporated) provide complete electrical equivalence to TSMBJ1010C with 400A peak pulse current rating, 180V breakover voltage, and identical package configuration. Both are active products with ROHS3 compliance, making them suitable for new designs and production transitions from the obsolete TSMBJ1010C.

Secondary Substitute (Reduced Peak Pulse Current):

SMP100MC-140 (STMicroelectronics) maintains all critical parameters except peak pulse current (8/20µs), which is rated at 300A versus the 400A requirement. This part is suitable only for applications where 300A peak pulse current is acceptable. SMP100LC-140 (STMicroelectronics) provides full 400A peak pulse current equivalence and is an alternative to primary substitutes.

Compliance Consideration:

All active substitute parts meet ROHS3 compliance requirements, addressing regulatory requirements not met by the obsolete TSMBJ1010C. Selection should prioritize active products with current compliance certifications for new production.

Frequently Asked Questions (FAQ)

Q: Can SMP100MC-140 replace TSMBJ1010C in all applications?

A: SMP100MC-140 is suitable only for applications tolerating 300A peak pulse current (8/20µs). The TSMBJ1010C is rated for 400A. Verify application requirements before substitution.

Q: What is the difference between the substitute parts in terms of capacitance?

A: Capacitance values range from 55pF to 120pF across substitutes. TSMBJ1010C and TB1500H-13-F both specify 120pF, while Littelfuse and STMicroelectronics parts specify lower values (55–65pF). Capacitance differences may affect high-frequency transient response characteristics; verify application requirements.

Q: Are all substitute parts available in the same packaging format?

A: All substitutes use DO-214AA (SMB) surface mount package. Packaging formats vary: P1500SCMCLRP and TB1500H-13-F are supplied in Tape & Reel (TR), while SMP100LC-140 is available in Cut Tape (CT) & Digi-Reel®, and SMP100MC-140 in Tape & Reel (TR). Confirm packaging compatibility with procurement requirements.

Q: Why is TSMBJ1010C obsolete?

A: Product status is obsolete. Active substitutes from Littelfuse, STMicroelectronics, and Diodes Incorporated provide equivalent or superior functionality with current RoHS compliance and ongoing manufacturing support.

Q: What is the breakover voltage tolerance across substitutes?

A: TSMBJ1010C and primary substitutes specify 180V breakover. SMP100LC-140 and SMP100MC-140 specify 175V. Both values fall within acceptable operating ranges for transient suppression; verify application voltage thresholds.
