TSMBJ1022C-TP Equivalent & Substitute Parts

Part Overview

The TSMBJ1022C-TP is a 275V off-state, 400A peak pulse transient voltage suppressor (TVS) thyristor manufactured by Micro Commercial Co in DO-214AA (SMB) surface mount package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The part operates with a 350V breakover voltage and 5V on-state voltage, designed for transient suppression applications requiring high peak pulse current handling in compact surface mount form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for TVS thyristor devices is determined by strict equivalence across the following critical parameters:

• Voltage - Breakover: 350V
• Voltage - Off State: 275V
• Current - Peak Pulse (8/20µs): 400A minimum
• Current - Hold (Ih): 150mA
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• RoHS and MSL compliance status

Two substitute parts are identified:

P3100SCMCLRP (Littelfuse Inc.) — Direct equivalent meeting all critical electrical and mechanical parameters with identical 400A peak pulse current rating and active product status.

TISP4350T3BJR-S (Bourns Inc.) — Similar substitute with reduced peak pulse current (250A vs. 400A) and lower on-state voltage (3V vs. 5V), suitable for applications with lower transient current requirements.

Parameter Comparison

Engineering Selection Recommendations

P3100SCMCLRP is the primary substitute for TSMBJ1022C-TP. Both parts maintain identical electrical specifications across all critical parameters: 350V breakover, 275V off-state, 400A peak pulse current (8/20µs), and 150mA hold current. P3100SCMCLRP carries active product status from Littelfuse Inc., ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant with MSL 1 rating and identical package configuration (DO-214AA, SMB). The primary difference is capacitance (45pF vs. 80pF), which does not affect substitution eligibility for standard transient suppression applications.

TISP4350T3BJR-S is a similar substitute suitable only for applications where peak pulse current requirements do not exceed 250A. This part reduces peak pulse current from 400A to 250A and on-state voltage from 5V to 3V. TISP4350T3BJR-S is active from Bourns Inc. and maintains ROHS3 compliance and MSL 1 rating. However, REACH status differs (REACH Affected vs. REACH Unaffected), requiring compliance verification for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can P3100SCMCLRP directly replace TSMBJ1022C-TP without circuit modification?

A: Yes. P3100SCMCLRP meets all critical electrical parameters: 350V breakover, 275V off-state, 400A peak pulse current (8/20µs), 150mA hold current, and identical DO-214AA SMB package. No circuit modification is required.

Q: What is the difference between the direct substitute and the similar substitute?

A: P3100SCMCLRP is a direct equivalent with identical 400A peak pulse current rating. TISP4350T3BJR-S is a similar substitute with reduced peak pulse current (250A) and lower on-state voltage (3V). Selection depends on application transient current requirements.

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

A: Yes. TSMBJ1022C-TP, P3100SCMCLRP, and TISP4350T3BJR-S all use DO-214AA (SMB) surface mount package with identical mechanical footprint and mounting type.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. P3100SCMCLRP and TSMBJ1022C-TP are REACH Unaffected. TISP4350T3BJR-S is REACH Affected, requiring compliance verification for regulated applications.

Q: Why is TSMBJ1022C-TP classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Micro Commercial Co. P3100SCMCLRP and TISP4350T3BJR-S are active products from established manufacturers, providing long-term design support and procurement availability.
