Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching critical electrical and mechanical parameters, including type (zener), bidirectional channel count, voltage ratings (reverse standoff, breakdown, and clamping), peak pulse current and power ratings, operating temperature, package/case form factor, mounting method, RoHS compliance status, and Moisture Sensitivity Level (MSL). Only models adhering strictly to these requirements are considered viable direct substitutes.

Key substitution criteria:

• Zener type, bidirectional channel configuration
• 145V reverse standoff voltage
• Comparable breakdown and clamping voltages
• 2.6A peak pulse current
• 600W peak pulse power
• Surface mount, DO-214AA (SMB) package
• RoHS compliance
• MSL 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

For obsolete parts such as P6SMB170C, selection of alternatives is based on identical or higher compliance ratings and certifications. Substitute P6SMB170CA matches the RoHS compliance and Moisture Sensitivity Level (MSL 1 Unlimited), along with similar package and mounting requirements. Substitute selection aligns with documented inventory status and active part availability in the transient voltage suppressors category.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting TVS diodes in the SMB package category?
A1: Key criteria include matching type (zener), bidirectional channels, voltage ratings (reverse standoff, breakdown, clamping voltage), peak pulse current and power, operating temperature range, mounting type, package/case form factor, RoHS status, and MSL.

Q2: Is the P6SMB170CA a direct substitute for the P6SMB170C?
