TSMBJ1006C Equivalent & Substitute Parts

Part Overview

The TSMBJ1006C is a 75V off-state, 400A peak pulse (8/20µs) thyristor-based transient voltage suppressor manufactured by Micro Commercial Co in DO-214AA (SMB) surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage ratings, current handling capacity, and mechanical packaging to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

• Voltage - Off State: 75V (exact match required)
• Voltage - Breakover: 98V ±3V tolerance acceptable
• Current - Peak Pulse (8/20µs): 400A minimum
• Current - Hold (Ih): 150mA (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Considerations:

• Product Status: Active preferred (obsolete parts not suitable for new designs)
• RoHS Compliance: ROHS3 Compliant preferred for regulatory alignment
• Voltage - On State: Variation acceptable within 1V to 5V range

Parts meeting all primary requirements are classified as direct electrical equivalents. Variations in capacitance and secondary voltage parameters do not preclude substitution when primary electrical characteristics align.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Full Compatibility):

P0900SCLRP and P0900SCMCLRP are direct electrical equivalents to TSMBJ1006C. Both parts maintain 75V off-state voltage, 98V breakover voltage, and 400A peak pulse current (8/20µs). Both are active products with ROHS3 compliance, eliminating obsolescence risk and meeting modern regulatory requirements. P0900SCMCLRP matches the original on-state voltage (5V), while P0900SCLRP operates at 4V on-state. TB0900H-13-F from Diodes Incorporated also qualifies as a direct equivalent with identical electrical specifications and active product status.

Partial Equivalents (Current Derating Required):

P0900SBLRP supports 250A peak pulse current, representing a 37.5% reduction from the original 400A specification. This part is suitable only for applications where peak pulse current requirements do not exceed 250A. P0900SALRP supports 150A peak pulse current and is applicable only to circuits designed for 150A or lower transient events.

Non-Equivalent (Voltage Mismatch):

SMP100LC-65 operates at 65V off-state voltage with 85V breakover voltage, representing a 10V reduction from the TSMBJ1006C specification. This part is not suitable for 75V-rated circuit protection and introduces voltage margin reduction.

Marginal Equivalent (Current Derating):

TISP4095H3BJR-S from Bourns supports 300A peak pulse current, a 25% reduction from the original 400A specification. Breakover voltage is 95V, within acceptable tolerance. This part is applicable only to applications where peak pulse current does not exceed 300A.

Frequently Asked Questions (FAQ)

Q: Can P0900SALRP replace TSMBJ1006C directly?

A: No. P0900SALRP is rated for 150A peak pulse current versus the original 400A specification. Direct replacement is not possible. Use only in applications designed for 150A or lower transient suppression.

Q: What is the difference between P0900SCLRP and P0900SCMCLRP?

A: Both parts are electrically equivalent with 400A peak pulse current and 75V off-state voltage. The primary difference is on-state voltage: P0900SCLRP operates at 4V while P0900SCMCLRP operates at 5V (matching the original TSMBJ1006C). Selection depends on circuit requirements for on-state voltage characteristics.

Q: Why is SMP100LC-65 listed if it cannot replace TSMBJ1006C?

A: SMP100LC-65 was included in the original substitute list but does not meet primary compatibility requirements due to 65V off-state voltage versus the required 75V specification. This part is not recommended for direct replacement.

Q: Are all substitute parts in DO-214AA (SMB) package?

A: Yes. All listed substitute parts use DO-214AA (SMB) surface mount package, ensuring mechanical and footprint compatibility with the original TSMBJ1006C.

Q: What is the significance of RoHS compliance for these parts?

A: The original TSMBJ1006C is RoHS non-compliant. All active substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory standards for new product designs and manufacturing.

Q: Can TISP4095H3BJR-S be used in place of TSMBJ1006C?

A: TISP4095H3BJR-S is suitable only for applications where peak pulse current does not exceed 300A. The 25% current reduction and 95V breakover voltage (versus 98V) may be acceptable depending on circuit design margins. Verify application requirements before substitution.
