S8006VTP Equivalent & Substitute Parts

Part Overview

The S8006VTP is an 800V, 6A standard recovery SCR (silicon-controlled rectifier) manufactured by Littelfuse Inc., housed in a TO-251 through-hole package. This thyristor is designed for applications requiring controlled rectification and switching at moderate current levels with standard gate sensitivity characteristics. The part maintains active product status with 736 units in current inventory.

Substitute parts are identified when equivalent voltage ratings, current handling capabilities, and thermal operating ranges align with the original specification, enabling direct functional replacement in circuit designs while accommodating package and mounting differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S8006VTP is determined by matching the following critical parameters:

• Voltage Rating (Off State): Must equal 800V to maintain blocking voltage capability
• Current Rating (RMS): Must meet or exceed 6A to handle the design current without derating
• Gate Trigger Characteristics: Vgt and Igt values must remain within acceptable ranges to ensure reliable gate drive compatibility
• On-State Voltage Drop: Vtm must be comparable to minimize thermal dissipation changes
• Operating Temperature Range: Must encompass the -40°C to 125°C specification
• Product Status: Active status ensures continued availability and support

The MCR12DSN-1G qualifies as a substitute based on matching 800V off-state voltage, exceeding the 6A current requirement at 12A RMS, maintaining compatible gate trigger parameters, and sharing active product status with full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the S8006VTP and MCR12DSN-1G maintain active product status and full RoHS3 compliance, ensuring regulatory alignment and long-term supply continuity. The MCR12DSN-1G provides higher current capacity (12A vs. 6A RMS) and sensitive gate characteristics (lower Vgt and Igt), which reduce gate drive requirements and improve circuit efficiency.

The primary design consideration is mounting compatibility: the S8006VTP uses through-hole TO-251 packaging, while the MCR12DSN-1G employs surface-mount TO-252 (DPAK) packaging. Circuit board layout and assembly process must accommodate this package difference. The MCR12DSN-1G's maximum operating temperature of 110°C is 15°C lower than the S8006VTP specification; applications requiring operation above 110°C must retain the original part.

Frequently Asked Questions (FAQ)

Q: Can MCR12DSN-1G directly replace S8006VTP in all applications?

A: Functional replacement is possible for applications operating within the MCR12DSN-1G temperature range (-40°C to 110°C) and using surface-mount assembly. The higher current rating and sensitive gate characteristics are compatible with S8006VTP circuit designs. Package and mounting differences require PCB redesign.

Q: What is the difference between standard recovery and sensitive gate SCRs?

A: Standard recovery SCRs (S8006VTP) require higher gate trigger current (15 mA max) for reliable turn-on. Sensitive gate SCRs (MCR12DSN-1G) require significantly lower gate trigger current (0.2 mA max), reducing gate drive circuit complexity and power consumption.

Q: Does the higher current rating of MCR12DSN-1G affect thermal performance?

A: The MCR12DSN-1G's on-state voltage drop (Vtm) is 1.9V compared to 1.6V for the S8006VTP. At equivalent current levels, this results in higher power dissipation. Thermal management design must account for this 0.3V difference in forward voltage.

Q: Are both parts available in the same packaging?

A: No. The S8006VTP uses through-hole TO-251 packaging; the MCR12DSN-1G uses surface-mount TO-252 (DPAK) packaging. Assembly method and PCB layout must be adapted accordingly.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.30.0080. Moisture sensitivity level is 1 (unlimited) for both parts.
