P2000SBLRP Equivalent & Substitute Parts

Part Overview

The P2000SBLRP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., classified as a SIDACtor® device. This component operates at 180V off-state voltage with a peak pulse current rating of 250A (8/20µs). The device is actively produced and widely used in transient protection applications requiring high current suppression in compact surface-mount packages. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P2000SBLRP are identified based on the following critical parameters that determine functional equivalence:

• Voltage - Off State: Must match at 180V to ensure identical blocking voltage performance
• Package / Case: Must be DO-214AA, SMB to maintain mechanical and thermal compatibility
• Mounting Type: Must be Surface Mount for PCB assembly compatibility
• Current - Peak Pulse (8/20µs): Rated at or above 250A to meet or exceed transient suppression requirements
• RoHS Status: Must maintain ROHS3 Compliance for regulatory alignment

The SMTPA180 from STMicroelectronics meets the core substitution criteria with matching off-state voltage, identical package type, and active product status. Differences in peak pulse current ratings and hold current are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the P2000SBLRP and SMTPA180 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The P2000SBLRP provides higher peak pulse current capability at 250A (8/20µs) compared to the SMTPA180 at 150A. The SMTPA180 exhibits lower capacitance (25pF versus 95pF), which may be advantageous in high-frequency applications. Selection between these parts should be based on the specific current suppression requirements of the application and the acceptable range of breakover voltage (220V versus 240V).

Frequently Asked Questions (FAQ)

Q: Can SMTPA180 directly replace P2000SBLRP in all applications?

A: Direct replacement depends on application current requirements. The SMTPA180 is rated for 150A peak pulse (8/20µs), which is lower than the P2000SBLRP's 250A rating. If the application requires the full 250A suppression capability, the SMTPA180 may not be suitable. Both parts share identical off-state voltage (180V) and package type (DO-214AA, SMB).

Q: What is the significance of the breakover voltage difference?

A: The P2000SBLRP has a breakover voltage of 220V while the SMTPA180 is rated at 240V. This 20V difference affects the trigger threshold for transient suppression. Circuit design must account for this variance to ensure proper device activation during transient events.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AA, SMB package for surface-mount applications. The P2000SBLRP is supplied in Tape & Reel (TR) format, while the SMTPA180 is available in Cut Tape (CT) and Digi-Reel® formats. These are packaging and delivery method variations only; the component footprint and mounting requirements remain identical.

Q: How does capacitance affect substitution suitability?

A: The P2000SBLRP has 95pF capacitance while the SMTPA180 has 25pF. Lower capacitance in the SMTPA180 may reduce parasitic effects in high-frequency circuits but could affect performance in applications where the higher capacitance of the P2000SBLRP is relied upon for signal coupling or filtering characteristics.

Q: What compliance certifications apply to both parts?

A: Both the P2000SBLRP and SMTPA180 are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8541.30.0080. Moisture sensitivity level is 1 (Unlimited) for both devices.
