ESD2V8P8U-TP Equivalent & Substitute Parts

Part Overview

The ESD2V8P8U-TP is a 4-channel unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This component features a 2.8V reverse standoff voltage with an 8.5V maximum clamping voltage and 400W peak pulse power rating in an 8-SOIC surface mount package.

The ESD2V8P8U-TP is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESD2V8P8U-TP is determined by strict alignment of the following critical parameters:

• Reverse Standoff Voltage: 2.8V (Max) — must match to ensure proper circuit protection threshold
• Breakdown Voltage (Min): 3V — must match to maintain consistent trigger characteristics
• Package Type: 8-SOIC surface mount — must match for PCB compatibility and footprint alignment
• Unidirectional Channels: 4 — must match for circuit topology compatibility
• Zener Type: Must remain Zener-based TVS diode

The substitute part SLVU2.8-4-TP meets all critical substitution criteria. While this substitute exhibits higher clamping voltage (15V vs. 8.5V) and greater peak pulse power (600W vs. 400W), these represent performance enhancements that do not compromise compatibility. The substitute maintains identical reverse standoff voltage, breakdown voltage, channel configuration, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The SLVU2.8-4-TP is a direct substitute for the obsolete ESD2V8P8U-TP. Both components are manufactured by Micro Commercial Co and maintain identical critical electrical parameters: 2.8V reverse standoff voltage, 3V minimum breakdown voltage, 4-channel unidirectional configuration, and 8-SOIC package specification.

The SLVU2.8-4-TP offers the additional advantage of active product status, ensuring ongoing availability and supply chain support. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The substitute's enhanced clamping voltage (15V vs. 8.5V) and increased peak pulse power (600W vs. 400W) provide superior transient suppression capability without introducing compatibility issues. The extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 150°C) offers improved thermal performance margins.

Frequently Asked Questions (FAQ)

Q: Can SLVU2.8-4-TP directly replace ESD2V8P8U-TP without circuit modifications?

A: Yes. Both components share identical reverse standoff voltage (2.8V), breakdown voltage (3V), channel configuration (4-channel unidirectional), and package type (8-SOIC). Direct PCB footprint compatibility and electrical substitution are confirmed.

Q: Why does the substitute have higher clamping voltage and power rating?

A: The SLVU2.8-4-TP represents an enhanced design variant within the same product family. Higher clamping voltage and power rating indicate improved transient suppression performance while maintaining the same protection threshold characteristics. These enhancements do not compromise compatibility.

Q: Are there compliance or certification differences between the parts?

A: Both components maintain ROHS3 compliance and REACH unaffected status. No compliance or certification barriers exist for substitution.

Q: What is the significance of product status difference (Obsolete vs. Active)?

A: The ESD2V8P8U-TP is obsolete, meaning manufacturing has been discontinued. The SLVU2.8-4-TP is active, ensuring continued availability, technical support, and supply chain reliability for new designs and ongoing production requirements.

Q: Are there packaging or moisture sensitivity considerations?

A: Both components use identical 8-SOIC surface mount packaging. Both maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture handling requirements during storage or assembly.
