Parameter Comparison

Engineering Selection Recommendations

SMP15-M3/85A: This part is the primary substitute for the obsolete SMP15-M3/84A. It maintains identical electrical specifications including voltage clamping at 26.9V and peak pulse current of 14.9A. The part is currently in active production status with confirmed inventory availability. ROHS3 compliance and MSL Level 1 rating are maintained, ensuring compatibility with current manufacturing and environmental standards.

SMP15A-M3/84A: This alternative substitute shares the same voltage ratings and thermal operating range. It differs in clamping voltage (24.4V) and peak pulse current (16.4A), representing a higher current capability variant. This part is available in Tape & Reel packaging and maintains active production status. Selection of this variant requires confirmation that the lower clamping voltage specification aligns with circuit protection requirements.

Frequently Asked Questions (FAQ)

Q: Can SMP15-M3/85A be used as a direct replacement for SMP15-M3/84A?

A: Yes. SMP15-M3/85A maintains identical electrical specifications for voltage clamping (26.9V), peak pulse current (14.9A), and all thermal and compliance parameters. The primary difference is product status: SMP15-M3/85A is in active production while SMP15-M3/84A is obsolete.

Q: What is the difference between SMP15-M3/85A and SMP15A-M3/84A?

A: Both are active substitutes for the obsolete SMP15-M3/84A. SMP15-M3/85A provides identical electrical performance. SMP15A-M3/84A offers higher peak pulse current (16.4A vs. 14.9A) but with lower clamping voltage (24.4V vs. 26.9V). Selection depends on circuit requirements for clamping voltage and current handling capacity.

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

A: Yes. All parts use the DO-220AA surface mount package. SMP15A-M3/84A is additionally available in Tape & Reel packaging format for high-volume production requirements.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with current manufacturing processes and environmental regulations.

Q: What is the operating temperature range for these TVS diodes?

A: All parts in this substitution group operate across -55°C to 150°C junction temperature range, supporting applications across industrial and commercial temperature specifications.
