Equivalent & Substitute Parts for P4SMA200

Part Overview

The P4SMA200 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., rated for 171V reverse standoff voltage with 287.7V maximum clamping voltage at peak pulse current. Designed for general-purpose overvoltage protection in surface mount applications, this component operates across -65°C to 150°C. The P4SMA200 is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA200 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 171V and breakdown voltage minimum of 180.5V establish the protection threshold. Substitute parts must maintain these voltage specifications to ensure proper circuit protection.
• Package Compatibility: All substitutes must use DO-214AC (SMA) surface mount packaging to ensure mechanical and electrical compatibility with existing PCB layouts.
• Peak Pulse Power: 400W power dissipation rating must be maintained across all substitutes.
• Unidirectional Configuration: Single-channel zener diode topology required for general-purpose transient suppression.
• Compliance: RoHS3 compliance is mandatory for all substitutes.

The identified substitute parts P4SMA200A (Good-Ark Semiconductor) and SMAJP4KE200A-TP (Micro Commercial Co) meet these substitution criteria while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

P4SMA200A (Good-Ark Semiconductor) is suitable for applications where the reduced peak pulse current specification (1.1A versus 1.5A) is acceptable within circuit design margins. This part offers active product status, ROHS3 compliance, and REACH unaffected designation, ensuring regulatory compliance and supply continuity. The lower operating temperature minimum (-55°C versus -65°C) should be verified against application requirements.

SMAJP4KE200A-TP (Micro Commercial Co) maintains the original 1.5A peak pulse current rating and extends the maximum operating temperature to 175°C, providing enhanced thermal performance. This part is active, ROHS3 compliant, and REACH unaffected. The reduced minimum operating temperature (-55°C) requires verification for low-temperature applications.

Both substitutes maintain the 400W peak pulse power rating, DO-214AC packaging, and 171V reverse standoff voltage necessary for direct functional replacement of the obsolete P4SMA200.

Frequently Asked Questions (FAQ)

Q: Can P4SMA200A be used as a direct replacement for P4SMA200?

A: P4SMA200A is functionally equivalent for applications where peak pulse current of 1.1A meets design requirements. The clamping voltage is lower (274V versus 287.7V), and the minimum operating temperature is -55°C instead of -65°C. Verify these parameters against your circuit specifications before implementation.

Q: What is the difference between P4SMA200A and SMAJP4KE200A-TP?

A: Both parts share identical reverse standoff voltage (171V), breakdown voltage (190V minimum), and clamping voltage (274V maximum). The key difference is peak pulse current: P4SMA200A is rated 1.1A while SMAJP4KE200A-TP is rated 1.5A, matching the original P4SMA200. SMAJP4KE200A-TP also offers extended temperature range to 175°C.

Q: Are all substitute parts in the same package?

A: Yes. P4SMA200, P4SMA200A, and SMAJP4KE200A-TP all use DO-214AC (SMA) surface mount packaging, ensuring mechanical compatibility with existing PCB designs without layout modifications.

Q: Do the substitute parts meet RoHS and compliance requirements?

A: Both P4SMA200A and SMAJP4KE200A-TP are ROHS3 compliant with moisture sensitivity level 1 (unlimited). Both are REACH unaffected, meeting current regulatory standards for electronic component procurement.

Q: Which substitute should I select for new designs?

A: Selection depends on circuit requirements. If peak pulse current of 1.5A is necessary, use SMAJP4KE200A-TP. If 1.1A is sufficient and cost is a consideration, P4SMA200A is acceptable. Verify minimum operating temperature requirements: both substitutes operate to -55°C minimum, compared to -65°C for the original part.
