Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESD24VD3-TP is determined by the following critical parameters:

Voltage Compatibility: The reverse standoff voltage (24V maximum) and breakdown voltage (26.6V minimum) establish the primary voltage class. Substitute parts must maintain the same 24V standoff specification to ensure proper circuit protection thresholds.

Package Compatibility: The SOD-323 surface-mount package is a mandatory requirement for direct substitution. This package designation ensures mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Unidirectional Configuration: The ESD24VD3-TP operates as a unidirectional device with a single channel. Substitute parts must maintain this unidirectional topology to preserve circuit protection characteristics.

Operating Temperature Range: The -55°C to 150°C operating temperature range defines the thermal operating envelope. Substitute parts must support this temperature specification or a compatible superset.

Regulatory Compliance: RoHS3 compliance and MSL Level 1 rating are mandatory for supply chain and manufacturing compatibility.

The SD24C-TP meets all critical substitution criteria while offering enhanced electrical performance characteristics within the same package and voltage class.

Engineering Selection Recommendations

SD24C-TP as Primary Substitute

The SD24C-TP is the qualified substitute for the ESD24VD3-TP based on the following engineering criteria:

Voltage Class Alignment: Both devices maintain identical 24V reverse standoff voltage and comparable breakdown voltage specifications (26.6V vs. 26.7V), ensuring equivalent circuit protection thresholds.

Package Compatibility: Both components utilize the SOD-323 surface-mount package, enabling direct PCB layout compatibility without redesign.

Regulatory Compliance: The SD24C-TP maintains ROHS3 compliance and MSL Level 1 rating, satisfying supply chain and manufacturing requirements equivalent to the original component.

Product Status: The SD24C-TP is classified as Active, providing assured long-term availability and supply chain continuity compared to the obsolete ESD24VD3-TP.

Enhanced Performance Characteristics: The SD24C-TP offers increased peak pulse current capacity (8A versus 1A) and peak pulse power rating (350W), providing superior transient suppression capability within the same package footprint. These enhancements do not compromise circuit compatibility and support higher-energy transient events.

Operating Temperature Consideration: The SD24C-TP operates across -55°C to 125°C, which represents a 25°C reduction in the upper temperature limit compared to the ESD24VD3-TP (-55°C to 150°C). This difference is acceptable for most general-purpose applications; however, designs requiring operation above 125°C must evaluate thermal requirements independently.

Frequently Asked Questions (FAQ)

Q: Can the SD24C-TP directly replace the ESD24VD3-TP without circuit modification?

A: Yes. Both devices share identical 24V reverse standoff voltage, comparable breakdown voltage specifications, and the same SOD-323 package. Direct substitution is supported for general-purpose overvoltage protection applications.

Q: What is the significance of the higher peak pulse current rating in the SD24C-TP?

A: The SD24C-TP provides 8A peak pulse current capacity compared to 1A in the ESD24VD3-TP. This enhanced rating allows the substitute part to suppress higher-energy transient events while maintaining the same voltage protection thresholds and package form factor.

Q: Does the SD24C-TP operate across the same temperature range as the ESD24VD3-TP?

A: The SD24C-TP operates from -55°C to 125°C, while the ESD24VD3-TP operates from -55°C to 150°C. The substitute part has a 25°C lower upper temperature limit. Applications requiring operation above 125°C must verify thermal compatibility independently.

Q: Are both devices RoHS3 compliant?

A: Yes. Both the ESD24VD3-TP and SD24C-TP are ROHS3 compliant with MSL Level 1 rating, satisfying regulatory and supply chain requirements.

Q: Why is the ESD24VD3-TP classified as obsolete?

A: The ESD24VD3-TP is no longer in active production. The SD24C-TP is the active equivalent offering improved performance characteristics and assured long-term availability.

Q: What is the difference in capacitance between these devices?

A: The ESD24VD3-TP has 80pF capacitance at 1MHz, while the SD24C-TP has a maximum of 50pF at 1MHz. The lower capacitance in the substitute part may provide improved performance in high-frequency signal integrity applications.

Q: Is the packaging identical between both parts?

A: Yes. Both devices use the SC-76, SOD-323 surface-mount package, ensuring identical PCB footprint and assembly compatibility.
