All identified substitute parts maintain these core electrical and mechanical specifications within the tolerances required for direct substitution in the same circuit application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance. Selection among these equivalents depends on application-specific requirements:

1.5SMC36CA TR13 PBFREE (Central Semiconductor Corp) and 1.5SMC36CA (Taiwan Semiconductor Corporation) are direct electrical equivalents with identical voltage and power specifications. The Taiwan Semiconductor version offers higher peak pulse current (31A vs 30A) and extended upper operating temperature to 150°C.

SMCJ1.5KE36CA-TP (Micro Commercial Co) provides the widest operating temperature range (-55°C to 175°C) and meets general-purpose application requirements with 30.5A peak pulse current.

TPSMC36CA (Littelfuse) is qualified to AEC-Q101 automotive standards and carries REACH Affected status. This part is suitable for automotive-grade applications requiring formal qualification documentation.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SM15T36CA-M3/9AT with any of these parts in my circuit?

A: Yes. All listed parts maintain identical voltage clamping (49.9V), reverse standoff (30.8V), and power dissipation (1500W) specifications. Peak pulse current varies slightly (30A to 31A), which remains within acceptable tolerance for the 36V protection class.

Q: What is the difference between the Central Semiconductor and Taiwan Semiconductor versions?

A: Both 1.5SMC36CA variants meet the same electrical specifications. The Taiwan Semiconductor version specifies 31A peak pulse current versus 30A for Central Semiconductor, and both operate to 150°C maximum junction temperature.

Q: Does the Littelfuse TPSMC36CA require different PCB layout or assembly procedures?

A: No. The TPSMC36CA uses the same DO-214AB (SMC) package footprint and mounting type as the original part. Assembly and layout considerations remain identical.

Q: Why does the Littelfuse part have AEC-Q101 qualification?

A: AEC-Q101 is an automotive industry qualification standard. The TPSMC36CA is qualified to this standard for use in automotive applications where formal component qualification is required.

Q: Are there any temperature range limitations I should consider?

A: The original SM15T36CA-M3/9AT operates to -65°C minimum. The 1.5SMC36CA (Taiwan Semiconductor) and TPSMC36CA (Littelfuse) operate to -55°C minimum. If your application requires operation below -55°C, use the original Vishay part or Central Semiconductor equivalent.

Q: What does REACH Affected status mean for the Littelfuse part?

A: REACH Affected indicates the component may contain substances of concern under EU REACH regulations. This does not affect electrical performance but may impact supply chain compliance requirements for your application.
