• Voltage - Reverse Standoff: 5V (Max)
• Voltage - Breakdown: 6V (Min)
• Voltage - Clamping: 11V (Max) @ Ipp
• Current - Peak Pulse: 3A (8/20µs)
• Power - Peak Pulse: 33W
• Capacitance: 19pF @ 1MHz
• Operating Temperature: -40°C ~ 125°C (TJ)
• Type: Zener, Unidirectional
• Mounting: Surface Mount
• RoHS Compliance: ROHS3 Compliant

The VESD05A1B-HD1-GS08 meets all electrical parameter requirements for direct substitution. While the package designation differs (LLP1006-2L versus SOD-923), both are surface-mount implementations of the same base product (VESD05) with identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The VESD05A1B-HD1-GS08 is the direct electrical equivalent for the obsolete VESD05A1B-02Z-GS08. Both components share identical electrical specifications and are manufactured by the same supplier under the same base product number (VESD05).

The VESD05A1B-HD1-GS08 carries Active product status with significantly higher inventory availability (108,700 pcs versus 4,691 pcs), ensuring long-term supply chain reliability. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Package differences (SOD-923 to SOD-882/LLP1006-2L) require PCB layout verification to confirm footprint compatibility. Electrical performance and thermal characteristics remain equivalent across both package options.

Frequently Asked Questions (FAQ)

Q: Can VESD05A1B-HD1-GS08 directly replace VESD05A1B-02Z-GS08 in existing designs?

A: Electrical substitution is direct. All voltage, current, power, and thermal specifications are identical. PCB footprint compatibility must be verified, as the package designations differ (SOD-923 versus SOD-882/LLP1006-2L).

Q: What is the primary reason for substitution?

A: The VESD05A1B-02Z-GS08 is classified as obsolete. The VESD05A1B-HD1-GS08 provides equivalent electrical performance with active product status and superior inventory availability.

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