P4SMA30A Equivalent & Substitute Parts

Part Overview

The P4SMA30A is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for surface mount applications in the DO-214AC (SMA) package. This component provides transient voltage protection with a reverse standoff voltage of 25.6V and peak pulse current handling of 9.9A. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4SMA30A are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Voltage - Reverse Standoff (Typ): 25.6V
• Voltage - Breakdown (Min): 28.5V
• Voltage - Clamping (Max) @ Ipp: 41.4V
• Current - Peak Pulse (10/1000µs): 9.9A
• Power - Peak Pulse: 400W
• Operating Temperature Range: -55°C to 150°C (TJ)
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Type: Zener
• Unidirectional Channels: 1

Parts meeting all these parameters are classified as direct substitutes. The P4SMA30A from Eaton - Electronics Division meets all specified electrical and mechanical requirements and is therefore a valid equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns Inc. P4SMA30A and Eaton P4SMA30A are active production parts with full compliance certifications. The Bourns part carries ROHS3 compliance, while the Eaton part carries RoHS compliance. Both parts maintain identical electrical specifications, temperature operating range, and package configuration. Selection between these parts may be based on supplier availability, lead time, or established procurement agreements. Both parts are suitable for direct substitution in applications requiring 25.6V reverse standoff protection with 9.9A peak pulse current handling in surface mount DO-214AC (SMA) packaging.

Frequently Asked Questions (FAQ)

Q: Can the Eaton P4SMA30A replace the Bourns P4SMA30A in existing designs?

A: Yes. Both parts share identical electrical parameters (25.6V reverse standoff, 28.5V breakdown minimum, 41.4V clamping maximum, 9.9A peak pulse current, 400W peak pulse power), operating temperature range (-55°C to 150°C), and package configuration (DO-214AC, SMA surface mount). Direct substitution is supported.

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

A: The Bourns part is ROHS3 compliant, while the Eaton part is RoHS compliant. Both meet regulatory requirements for their respective markets. Verify compliance requirements for your specific application and region.

Q: What is the significance of the DO-214AC (SMA) package designation?

A: DO-214AC and SMA refer to the same surface mount package for this TVS diode. Both designations are equivalent and indicate a standardized two-terminal surface mount form factor suitable for automated assembly processes.

Q: Are moisture sensitivity levels identical between these parts?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: What applications are these parts suitable for?

A: The Bourns part is specified for general purpose transient voltage suppression. The Eaton part is specified for telecom applications. Both parts meet the same electrical and mechanical specifications and can be used interchangeably in applications requiring 25.6V standoff protection with 9.9A peak pulse current handling.
