P4SMA110A Equivalent & Substitute Parts

Part Overview

The P4SMA110A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 94V reverse standoff voltage, 152V maximum clamping voltage, and 2.7A peak pulse current capability in a DO-214AC (SMA) package. The part is Active status and RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4SMA110A is determined by the following criteria:

• Package compatibility: DO-214AC (SMA) surface-mount package required
• Unidirectional channel configuration: Single channel only
• Voltage parameters: Reverse standoff voltage, breakdown voltage, and clamping voltage must fall within acceptable ranges for the application
• Current rating: Peak pulse current must support the 2.7A specification
• Power dissipation: Peak pulse power rating of 400W
• Compliance: RoHS3 compliance and REACH unaffected status required
• Product status: Active status preferred for long-term availability

The SMAJ110A-TP from Micro Commercial Co meets these substitution criteria through equivalent package, channel configuration, and compliance certifications, with variations in specific voltage and current parameters within acceptable operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Both the P4SMA110A and SMAJ110A-TP are Active status components with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory compliance for current and future applications. The SMAJ110A-TP operates across a wider temperature range (-55°C to 175°C TA versus -65°C to 150°C TJ), providing extended thermal performance in certain operating environments. Selection between these parts should be based on specific circuit voltage requirements and thermal operating conditions, with both components suitable for general-purpose transient voltage suppression in surface-mount applications.

Frequently Asked Questions (FAQ)

Q: Can SMAJ110A-TP directly replace P4SMA110A in all applications?

A: Both parts share identical package geometry (DO-214AC, SMA), mounting type (surface mount), and power rating (400W). Substitution is valid when the application voltage requirements accommodate the SMAJ110A-TP's higher standoff voltage (110V vs 94V) and clamping voltage (177V vs 152V). Circuit design must confirm compatibility with these parameter differences.

Q: What are the key voltage differences between these parts?

A: The P4SMA110A provides lower voltage thresholds (94V standoff, 152V clamp), while the SMAJ110A-TP operates at higher voltage levels (110V standoff, 177V clamp). The SMAJ110A-TP's peak pulse current is 2.3A compared to 2.7A for the P4SMA110A. Applications requiring the lower voltage protection of the P4SMA110A cannot use the SMAJ110A-TP as a substitute.

Q: Are there packaging or moisture sensitivity differences?

A: Both components use DO-214AC (SMA) surface-mount packaging with Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity concerns for storage or handling.

Q: What compliance certifications apply to both parts?

A: Both the P4SMA110A and SMAJ110A-TP are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: How do operating temperature ranges differ?

A: The P4SMA110A operates from -65°C to 150°C (junction temperature), while the SMAJ110A-TP operates from -55°C to 175°C (ambient temperature). Applications requiring operation below -55°C or above 150°C may have different compatibility requirements between these parts.
