P6SMB480A-M3/5B Equivalent & Substitute Parts
Part Overview
The P6SMB480A-M3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 408V reverse standoff voltage class and provides transient protection with a 658V maximum clamping voltage. The part is Active status and widely used in general purpose transient suppression applications. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the DO-214AA/SMB package family.

Engineering Selection Recommendations
The P6SMB480A from Eaton qualifies as a direct electrical substitute for the P6SMB480A-M3/5B from Vishay based on matched voltage ratings, clamping characteristics, and power dissipation specifications. Both parts maintain Active product status and comply with RoHS and REACH requirements.
Selection Considerations:
- Electrical Compatibility: Peak pulse current differs by 10mA (910mA vs 900mA), which is within acceptable engineering tolerance for TVS diode applications
- Temperature Range: The Eaton part operates from -55°C minimum versus -65°C for the Vishay part. Verify application requirements if operation below -55°C is required
- Packaging Format: Vishay supplies in Tape & Box format; Eaton supplies in Tape & Reel format. Confirm procurement and assembly compatibility with your supply chain
- Compliance: Both parts meet RoHS and REACH requirements for regulated markets
Frequently Asked Questions (FAQ)
Q: Can the P6SMB480A (Eaton) be used as a direct replacement for P6SMB480A-M3/5B (Vishay)?
A: Yes, the Eaton P6SMB480A qualifies as an electrical substitute. All critical voltage parameters (reverse standoff, breakdown, and clamping) are matched. Peak pulse current differs by 10mA, which is within acceptable tolerance for TVS diode applications. Verify packaging format compatibility with your assembly process.
Q: What are the key parameters that determine substitution eligibility?
A: Substitution is based on: reverse standoff voltage (408V), breakdown voltage minimum (456V), clamping voltage (658V), peak pulse current rating (910mA nominal), power dissipation (600W), DO-214AA/SMB package compatibility, and unidirectional Zener-type configuration.
Q: Does the operating temperature range difference affect substitution?
A: The Eaton part has a minimum operating temperature of -55°C versus -65°C for the Vishay part. If your application requires operation below -55°C, the Eaton substitute may not be suitable. Confirm your application's temperature requirements before selection.
Q: Are there compliance differences between the two parts?
A: Both parts comply with RoHS and REACH requirements. The Vishay part is ROHS3 Compliant; the Eaton part is RoHS Compliant. Both are acceptable for regulated markets.
Q: What is the difference between Tape & Box and Tape & Reel packaging?
A: Tape & Box (TB) packaging is typically used for smaller quantities and manual handling. Tape & Reel (TR) packaging is standard for automated assembly lines. Confirm your assembly process requirements before ordering.
Q: Are there any application differences between the two parts?
A: The Vishay part is specified for General Purpose applications; the Eaton part is specified for Telecom applications. Both parts meet the same electrical specifications and can function in either application domain based on their electrical characteristics.
