Substitute Part Grouping Explanation

Substitution of the GSOT36-HT3-GS08 is determined by electrical parameter equivalence and compliance alignment. The primary substitute identified is the GSOT36-E3-08, which shares the same base product number (GSOT36) and maintains identical electrical specifications across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, power dissipation, and capacitance characteristics.

The key substitution criteria are:

• Voltage - Reverse Standoff: 36V nominal
• Voltage - Breakdown (Min): 39V
• Voltage - Clamping (Max) @ Ipp: 71V
• Current - Peak Pulse: 3.5A (8/20µs)
• Power - Peak Pulse: 248W
• Capacitance @ 1MHz: 52pF
• Operating Temperature Range: -40°C ~ 125°C
• Zener type, unidirectional configuration
• Surface mount technology
• RoHS3 compliance

The GSOT36-E3-08 qualifies as a direct functional equivalent despite packaging differences, as it maintains all electrical performance parameters within the specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

The GSOT36-E3-08 is the recommended substitute for the obsolete GSOT36-HT3-GS08. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical specifications across all critical performance parameters. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain RoHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels. The primary design consideration is the package transition from LLP75-3B (3-WDFN) to SOT-23-3 (TO-236-3, SC-59). This packaging change requires PCB layout modification but does not affect electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the GSOT36-E3-08 be used as a direct replacement for the GSOT36-HT3-GS08?

A: Yes, the GSOT36-E3-08 is electrically equivalent to the GSOT36-HT3-GS08. All critical electrical parameters—reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, power dissipation, and capacitance—are identical. The substitute part is actively manufactured and available.

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

A: The main difference is the package type. The GSOT36-HT3-GS08 uses the LLP75-3B package (3-WDFN), while the GSOT36-E3-08 uses the SOT-23-3 package (TO-236-3, SC-59). Both are surface mount packages suitable for automated assembly.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical compliance status: RoHS3 compliant, REACH unaffected, and EAR99 export classification. Both have MSL 1 (unlimited moisture sensitivity level).

Q: Does the package change affect circuit performance?

A: The electrical performance remains unchanged. The SOT-23-3 package has different physical dimensions and pin layout compared to the LLP75-3B package, requiring PCB redesign. However, the electrical characteristics and transient voltage suppression performance are identical.

Q: What is the inventory status of the substitute part?

A: The GSOT36-E3-08 has 22,707 pieces in stock as new original inventory, ensuring immediate availability for production requirements.
