ACTT10B-800CTNJ Equivalent & Substitute Parts

Part Overview

The ACTT10B-800CTNJ is a Standard TRIAC manufactured by WeEn Semiconductors, rated for 800V off-state voltage and 10A on-state current in a Surface Mount D2PAK package. This component is Active in product status and RoHS Compliant. Equivalent and substitute parts are identified based on matching electrical ratings, package compatibility, and operational parameters to ensure direct functional replacement in circuit applications.

Voltage - Gate Trigger (Vgt) (Max)	1 V
Current - Gate Trigger (Igt) (Max)	35 mA
Current - Hold (Ih) (Max)	30 mA
Package / Case	TO-263-3, D2PAK (2 Leads + Tab)
Mounting Type	Surface Mount
Operating Temperature (TJ)	150°C
RoHS Status	RoHS Compliant

Substitute Part Grouping Explanation

Substitute parts for the ACTT10B-800CTNJ are identified based on the following critical parameters:

Voltage Rating (Off State): 800V minimum to maintain equivalent circuit protection and switching capability
Package Type: D2PAK (TO-263-3) Surface Mount for mechanical and thermal compatibility
Configuration: Single TRIAC configuration
Gate Trigger Parameters: Vgt and Igt ratings within acceptable operating ranges for gate drive circuit compatibility
Hold Current (Ih): Maximum 30mA to ensure consistent latching behavior

The ACST830-8GTR from STMicroelectronics meets these substitution criteria. While its on-state current rating is 8A (compared to 10A for the main part), it maintains the same 800V voltage rating, D2PAK package, and compatible gate trigger specifications. This part is suitable for applications where the 8A rating is sufficient for the circuit design.

Engineering Selection Recommendations

Both the ACTT10B-800CTNJ and ACST830-8GTR are Active products with current manufacturing support. The ACST830-8GTR carries ROHS3 Compliant status, providing enhanced environmental compliance. Selection between these parts depends on circuit current requirements: the ACTT10B-800CTNJ supports 10A on-state current, while the ACST830-8GTR is rated for 8A. For applications requiring the full 10A capability, the ACTT10B-800CTNJ is the appropriate choice. For circuits designed for 8A operation or lower, the ACST830-8GTR provides equivalent functionality with identical voltage ratings and package compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ACST830-8GTR directly replace the ACTT10B-800CTNJ?

A: Direct replacement is possible only if the circuit design operates at or below 8A on-state current. Both parts share the same 800V voltage rating, D2PAK package, and gate trigger specifications. If the application requires the full 10A capability of the ACTT10B-800CTNJ, the ACST830-8GTR is not suitable.

Q: Are the D2PAK packages identical between these parts?

A: Both parts use the TO-263-3 D2PAK (2 Leads + Tab) package. PCB footprints and thermal characteristics are compatible for direct substitution at the board level.

Q: What is the difference in gate trigger current between these parts?

A: The ACTT10B-800CTNJ has a maximum gate trigger current (Igt) of 35mA, while the ACST830-8GTR is rated at 30mA. Both values are within typical gate drive circuit specifications. Gate drive circuits designed for either specification will function with both parts.

Q: Do both parts meet RoHS requirements?

A: The ACTT10B-800CTNJ is RoHS Compliant. The ACST830-8GTR is ROHS3 Compliant, which represents a more recent environmental compliance standard. Both parts are suitable for RoHS-regulated applications.

Q: What is the significance of the non-repetitive surge current difference?

A: The ACTT10B-800CTNJ is rated for 90A (50Hz) and 99A (60Hz) non-repetitive surge current, while the ACST830-8GTR is rated for 80A (50Hz) and 84A (60Hz). These ratings define the maximum transient current the part can withstand. Applications with high inrush current requirements should account for this difference in part selection.
