SMP30A-M3/84A Equivalent & Substitute Parts

Part Overview

The SMP30A-M3/84A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is classified as a Zener-type TVS diode in the TransZorb® and eSMP® series, designed for general-purpose transient voltage suppression applications. The device is currently in Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when electrical characteristics, mechanical packaging, and operational parameters remain equivalent across manufacturing batches or minor design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMP30A-M3/84A is based on strict equivalence of the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 30V
• Voltage - Breakdown (Min): 33.3V
• Voltage - Clamping (Max) @ Ipp: 48.4V
• Current - Peak Pulse (10/1000µs): 8.3A
• Power - Peak Pulse: 400W
• Package / Case: DO-220AA (SMP)
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Type: Zener
• Series: TransZorb®, eSMP®

The substitute part SMP30A-M3/85A maintains identical electrical performance specifications and mechanical packaging. Both parts are manufactured by Vishay General Semiconductor - Diodes Division within the same product series and share the same base product number (SMP30). The difference in part number suffix reflects manufacturing batch or design revision tracking without alteration to functional parameters.

Parameter Comparison

Engineering Selection Recommendations

Both SMP30A-M3/84A and SMP30A-M3/85A are Active products with full RoHS3 compliance and REACH Unaffected status. Selection between these parts is based on availability and supply chain requirements rather than functional differentiation. Both components carry identical electrical ratings, thermal operating range, and mechanical packaging specifications. The MSL 1 rating (Unlimited) indicates no moisture sensitivity constraints for storage or handling. Component selection should prioritize inventory availability and lead time considerations, as electrical and compliance characteristics are fully equivalent.

Frequently Asked Questions (FAQ)

Q: Can SMP30A-M3/85A be used as a direct replacement for SMP30A-M3/84A?

A: Yes. Both parts are electrically and mechanically equivalent. All voltage ratings, current specifications, power dissipation, operating temperature range, and package dimensions are identical. The part number suffix difference does not indicate functional variation.

Q: Are there any differences in RoHS or environmental compliance between these parts?

A: No. Both parts maintain ROHS3 compliance and REACH Unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) is identical for both components.

Q: What is the significance of the part number suffix change from /84A to /85A?

A: The suffix reflects manufacturing batch or design revision tracking within Vishay's production system. This does not alter electrical performance, mechanical fit, or operational characteristics.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both components use identical Surface Mount packaging (DO-220AA SMP) and are compatible with standard reflow soldering processes. No process modifications are required when substituting between these parts.

Q: What inventory status should I consider when selecting between these parts?

A: SMP30A-M3/84A has 10,300 pieces in stock, while SMP30A-M3/85A has 10,617 pieces in stock. Selection should be based on immediate availability and supply chain lead time requirements.
