S8006DTP Equivalent & Substitute Parts

Part Overview

The S8006DTP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc., rated for 800V off-state voltage with 6A RMS on-state current capability. This thyristor is designed for surface mount applications in the TO-252 (DPAK) package and is classified as Standard Recovery type. The part is currently Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter ranges while accommodating different current ratings, gate sensitivity characteristics, or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S8006DTP is determined by the following criteria:

Mandatory Matching Parameters:

• Voltage - Off State: 800V (exact match required)
• Package / Case: TO-252-3 DPAK (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS3 Compliance: Required
• Operating Temperature Range: Must support -40°C to 125°C minimum

Allowable Variation Parameters:

• Current - On State (It RMS): May exceed 6A (higher current capability acceptable)
• SCR Type: Standard Recovery or Sensitive Gate (functional differences acceptable based on application requirements)
• Gate Trigger Parameters (Vgt, Igt): May vary within standard thyristor operating ranges
• On-State Voltage (Vtm): Minor variations acceptable within semiconductor manufacturing tolerances

Identified Substitute Parts:

1. MCR12DSNT4G (Littelfuse Inc.) - Higher current rating, Sensitive Gate type
2. TN815-800B-TR (STMicroelectronics) - Higher current rating, Standard Recovery type

Parameter Comparison

Engineering Selection Recommendations

MCR12DSNT4G Substitution: This part maintains 800V off-state voltage and TO-252 DPAK package compatibility. The higher 12A RMS current rating provides increased thermal margin. The Sensitive Gate characteristic (1.0V Vgt, 0.2mA Igt) requires lower gate drive power compared to the S8006DTP. Operating temperature range extends to 110°C, which is 15°C lower than the S8006DTP maximum. All parts maintain ROHS3 compliance and Active product status. Tape & Reel packaging is suitable for automated assembly processes.

TN815-800B-TR Substitution: This STMicroelectronics part maintains 800V off-state voltage, TO-252 DPAK package compatibility, and Standard Recovery SCR type matching. The 8A RMS current rating exceeds the S8006DTP requirement. Gate trigger parameters (1.3V Vgt, 15mA Igt) align closely with the original part. Operating temperature range matches the S8006DTP at -40°C to 125°C. RoHS3 compliance and Active product status are maintained. Cut Tape and Digi-Reel packaging options support both manual and automated assembly.

Frequently Asked Questions (FAQ)

Q: Can MCR12DSNT4G replace S8006DTP in all applications? A: MCR12DSNT4G shares the same 800V voltage rating and TO-252 DPAK package. The higher 12A current rating and Sensitive Gate characteristics make it suitable for applications where lower gate drive current is beneficial. The maximum operating temperature of 110°C is 15°C lower than S8006DTP; verify this does not conflict with application thermal requirements.

Q: What is the difference between Standard Recovery and Sensitive Gate SCR types? A: Standard Recovery SCR (S8006DTP, TN815-800B-TR) requires higher gate trigger current (15mA) and voltage (1.5V, 1.3V respectively). Sensitive Gate SCR (MCR12DSNT4G) requires significantly lower gate trigger current (0.2mA) and voltage (1.0V), reducing gate drive circuit complexity and power consumption.

Q: Are all substitute parts available in the same packaging format? A: S8006DTP is supplied in Tube packaging. MCR12DSNT4G is supplied in Tape & Reel format. TN815-800B-TR is supplied in Cut Tape and Digi-Reel formats. Packaging format selection depends on assembly process requirements and volume considerations.

Q: Do all parts meet the same compliance standards? A: All three parts (S8006DTP, MCR12DSNT4G, TN815-800B-TR) are RoHS3 compliant, REACH unaffected, and classified as Active products. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: What is the current rating difference between substitute parts? A: S8006DTP is rated 6A RMS. TN815-800B-TR is rated 8A RMS. MCR12DSNT4G is rated 12A RMS. Higher current ratings provide additional thermal margin but do not reduce the maximum voltage capability.
