P6SMB220CA-M3/52 Equivalent & Substitute Parts Reference

Part Overview

The Vishay General Semiconductor P6SMB220CA-M3/52 is a surface-mount, bidirectional Transient Voltage Suppressor (TVS) diode, engineered for overvoltage protection in general-purpose applications. It features a 185V reverse standoff voltage, supports a 1.8A peak pulse current, and utilizes the DO-214AA (SMB) package type. The part is currently active, RoHS3 compliant, and has unlimited moisture sensitivity level (MSL 1).
Identifying equivalent or substitute TVS diodes is critical for supply chain flexibility, inventory assurance, and design compatibility, especially where packaging format, electrical, and environmental ratings are strictly controlled.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting P6SMB220CA-M3/52?
A1: Substitutes must have the same bidirectional configuration, minimum breakdown voltage, reverse standoff voltage, maximum clamping voltage, peak pulse current, peak pulse power rating, mounting type, and package/case.

Q2: Are there differences in package or mounting between these parts?
A2: All compared parts use the DO-214AA (SMB) package and are designed for surface-mount assembly.

Q3: Do differences in RoHS terminology affect substitutability?
A3: All substitutes are RoHS compliant, either as ROHS3 Compliant or RoHS Compliant, ensuring environmental and regulatory alignment.

Q4: What should be checked regarding compliance and qualification?
A4: The compared substitutes all have MSL 1 (Unlimited), and REACH unaffected status. ECCN classification matches (EAR99) in all cases.

Q5: Are there any performance-affecting differences?
A5: All parts have matching key electrical parameters. The Eaton P6SMB220CA specifies a slightly higher peak pulse current (1.9A), which remains within the category specifications provided above.
