P2000SA Equivalent & Substitute Parts

Part Overview

The P2000SA is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for transient overvoltage protection in surface mount applications. This component features a 180V off-state voltage rating with 150A peak pulse current capability in a DO-214AA (SMB) package. The P2000SA is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P2000SA are identified based on electrical and mechanical compatibility within the TVS thyristor category. The primary substitution criteria are:

• Voltage - Off State: 180V (exact match required)
• Voltage - Breakover: 220V to 240V range (acceptable tolerance for transient suppression)
• Current - Peak Pulse (8/20µs): 150A (exact match required)
• Package / Case: DO-214AA, SMB (mechanical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)

Two substitute parts meet these criteria: P2000SALRP (direct Littelfuse equivalent with different packaging) and SMTPA180 (STMicroelectronics alternative with comparable electrical performance).

Parameter Comparison

Engineering Selection Recommendations

P2000SALRP is the direct equivalent substitute for P2000SA. Both components are manufactured by Littelfuse Inc. with identical electrical specifications. The primary difference is packaging format: P2000SA is supplied in standard packaging while P2000SALRP is supplied in Tape & Reel (TR) format. P2000SALRP carries Active product status and ROHS3 compliance, making it the preferred choice for new designs and ongoing procurement.

SMTPA180 (STMicroelectronics) is an alternative substitute that meets the core electrical requirements. This component exhibits minor parameter variations: breakover voltage of 240V (versus 220V), peak pulse current at 10/1000µs of 50A (versus 45A), hold current of 150mA (versus 120mA), and capacitance of 25pF (versus 35pF). SMTPA180 is ROHS3 compliant and carries Active product status. Selection of SMTPA180 requires verification that the specified parameter variations are acceptable within the application circuit.

Frequently Asked Questions (FAQ)

Q: Can P2000SALRP be used as a direct replacement for P2000SA?

A: Yes. P2000SALRP is electrically and mechanically identical to P2000SA. The only difference is packaging format (Tape & Reel versus standard packaging). Both components share identical electrical specifications and the same DO-214AA, SMB package footprint.

Q: What are the key differences between SMTPA180 and P2000SA?

A: SMTPA180 differs in four parameters: breakover voltage (240V vs. 220V), peak pulse current at 10/1000µs (50A vs. 45A), hold current (150mA vs. 120mA), and capacitance (25pF vs. 35pF). The core specifications—180V off-state voltage, 150A peak pulse current at 8/20µs, and DO-214AA package—remain compatible.

Q: Is SMTPA180 suitable for all P2000SA applications?

A: SMTPA180 meets the primary electrical and mechanical requirements for TVS thyristor substitution. However, the parameter variations must be evaluated against specific circuit requirements. Applications with tight tolerances on breakover voltage, hold current, or capacitance may require additional circuit analysis.

Q: Why is P2000SA marked as obsolete?

A: P2000SA is classified as obsolete by the manufacturer. P2000SALRP provides continued availability with identical specifications and improved compliance status (ROHS3).

Q: Are both substitute parts available in the same package?

A: Yes. Both P2000SALRP and SMTPA180 are supplied in DO-214AA, SMB surface mount packages with identical mechanical compatibility to P2000SA.

Q: What compliance certifications apply to these substitutes?

A: P2000SALRP and SMTPA180 are both ROHS3 compliant. P2000SA is RoHS non-compliant. All three components are REACH unaffected and carry EAR99 ECCN classification.
