Substitute Part Grouping Explanation

Substitution of the GSOT05-HT3-GS08 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff: 5V nominal
• Voltage - Breakdown (Min): 6V
• Voltage - Clamping (Max) @ Ipp: 16V
• Current - Peak Pulse (10/1000µs): 30A (8/20µs)
• Power - Peak Pulse: 480W
• Capacitance @ Frequency: 260pF @ 1MHz
• Operating Temperature Range: -40°C ~ 125°C (TJ)

Mechanical & Compliance Criteria:

• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Type: Zener
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The GSOT05-E3-08 qualifies as a manufacturer-recommended substitute based on identical electrical performance specifications and compliance certifications. The primary difference is the package format: the substitute uses SOT-23-3 instead of the original 3-WDFN (LLP75-3B) package.

Parameter Comparison

Engineering Selection Recommendations

The GSOT05-E3-08 is the manufacturer-recommended substitute for the obsolete GSOT05-HT3-GS08. Both components maintain identical electrical performance specifications across all critical parameters: 5V reverse standoff voltage, 6V minimum breakdown voltage, 16V clamping voltage, and 30A peak pulse current handling capability.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The GSOT05-E3-08 carries Active product status with significantly higher inventory availability (16,865 pieces versus 800 pieces for the original part), ensuring long-term supply chain continuity.

The primary design consideration is the package transition from 3-WDFN (LLP75-3B) to SOT-23-3. This change requires PCB layout modification but does not affect electrical functionality. The SOT-23-3 package is a standard industry format with widespread design tool support and manufacturing compatibility.

Frequently Asked Questions (FAQ)

Q: Can GSOT05-E3-08 be used as a direct replacement for GSOT05-HT3-GS08?

A: Electrical substitution is complete. The GSOT05-E3-08 delivers identical voltage and current specifications. PCB layout modification is required due to package format change from 3-WDFN to SOT-23-3.

Q: What is the key difference between these two parts?

A: The GSOT05-HT3-GS08 uses a 3-WDFN package (LLP75-3B), while the GSOT05-E3-08 uses a SOT-23-3 package. Electrical performance is identical.

Q: Are both parts automotive-grade?

A: The GSOT05-HT3-GS08 carries automotive grade designation with AEC-Q101 qualification. The GSOT05-E3-08 specifications provided do not include automotive grade designation in the input data.

Q: What is the availability status of each part?

A: GSOT05-HT3-GS08 is classified as Obsolete with 800 pieces in stock. GSOT05-E3-08 is Active with 16,865 pieces in stock, providing superior long-term availability.

Q: Do both parts meet current compliance standards?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Is the SOT-23-3 package suitable for high-current TVS applications?

A: The SOT-23-3 package is rated for the same 30A peak pulse current and 480W peak pulse power as the original 3-WDFN package, confirming thermal and electrical adequacy for this application.
