P4SMA110C Equivalent & Substitute Parts

Part Overview

The P4SMA110C is a bidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) surface mount package, rated for 94V reverse standoff voltage and 400W peak pulse power. Designed for general-purpose transient protection applications, this component operates across -65°C to 150°C. The main part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4SMA110C is determined by the following critical parameters:

• Reverse Standoff Voltage (Typ): 94V
• Peak Pulse Power: 400W
• Current - Peak Pulse (10/1000µs): 2.7A nominal
• Package / Case: DO-214AC (SMA) surface mount
• Bidirectional Channels: 1
• Type: Zener TVS Diode

Substitute parts must maintain compatibility within the following tolerance ranges:

• Voltage - Clamping (Max) @ Ipp: 152V to 159.6V
• Voltage - Breakdown (Min): 99V to 105V
• Current - Peak Pulse: 2.6A to 2.7A
• Operating Temperature: minimum -55°C to 150°C or better
• Package configuration: DO-214AC or SMA equivalent

All identified substitutes meet these electrical and mechanical parameters while maintaining surface mount compatibility and 400W power rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status)

P4SMA110CA (Eaton - Electronics Division) and P4SMA110CAH (Taiwan Semiconductor Corporation) are the preferred substitutes. Both maintain 94V reverse standoff voltage, 2.7A peak pulse current, and 400W power rating. P4SMA110CAH carries AEC-Q101 automotive qualification and is suitable for applications requiring automotive-grade components. Both are available in active production status with RoHS compliance.

Secondary Substitute (Extended Temperature Range)

SMAJP4KE110CA-TP (Micro Commercial Co) extends the operating temperature range to -55°C to 175°C, providing additional thermal margin for high-temperature applications. This part maintains electrical specifications within acceptable tolerance and is suitable for general-purpose applications requiring elevated temperature performance.

Alternative (Different Manufacturer)

P4SMA110C (Taiwan Semiconductor Corporation) offers an active alternative with comparable electrical performance. The reverse standoff voltage is specified at 89.2V (lower than the 94V nominal), and peak pulse current is 2.6A. This part is suitable for applications where the slightly lower standoff voltage is acceptable within system design margins.

Compliance Considerations

All active substitutes maintain RoHS compliance. P4SMA110CAH includes REACH Unaffected status and AEC-Q101 qualification for automotive applications. Selection should be based on application requirements, temperature operating range, and any automotive or industrial qualification mandates.

Frequently Asked Questions (FAQ)

Q: Can P4SMA110CA be used as a direct replacement for the obsolete P4SMA110C?

A: Yes. P4SMA110CA maintains the same 94V reverse standoff voltage, 2.7A peak pulse current, 400W power rating, and DO-214AC (SMA) package. The clamping voltage is 152V compared to 159.6V in the original, which is within acceptable substitution tolerance for transient suppression applications. Operating temperature range is -55°C to 150°C versus the original -65°C to 150°C.

Q: What is the difference between P4SMA110CAH and P4SMA110CA?

A: Both parts share identical electrical specifications (94V standoff, 2.7A peak pulse, 152V clamping). P4SMA110CAH is qualified to AEC-Q101 automotive standard and carries REACH Unaffected status, making it suitable for automotive and regulated applications. P4SMA110CA is specified for telecom applications.

Q: Is SMAJP4KE110CA-TP compatible with the original P4SMA110C?

A: SMAJP4KE110CA-TP is electrically compatible, maintaining 94V reverse standoff voltage, 2.7A peak pulse current, and 400W power rating. The package designation is DO-214AC (SMAJ) rather than standard SMA, but both are surface mount variants of the same form factor. The extended operating temperature range (-55°C to 175°C) provides additional thermal capability.

Q: Why does the Taiwan Semiconductor P4SMA110C show 89.2V reverse standoff instead of 94V?

A: The reverse standoff voltage specification of 89.2V is within the P4SMA110 series tolerance band. The breakdown voltage minimum is specified at 99V, which meets the functional requirement. This part is suitable for applications where the lower standoff voltage is acceptable within system design margins.

Q: Are all substitute parts RoHS compliant?

A: P4SMA110CA (Eaton), P4SMA110C (Taiwan Semiconductor), and P4SMA110CAH (Taiwan Semiconductor) are all RoHS compliant. SMAJP4KE110CA-TP RoHS status is not specified in the provided data.

Q: Which substitute should I select for a new design?

A: For active production designs, select from P4SMA110CA or P4SMA110CAH based on application requirements. Use P4SMA110CAH for automotive applications requiring AEC-Q101 qualification. Use P4SMA110CA for general-purpose or telecom applications. Both are in active production with established supply chains.
