S2006DRP SCR 200V 6A TO-252 Equivalent & Substitute Parts

Part Overview

The S2006DRP is a Silicon Controlled Rectifier (SCR) rated for 200V off-state voltage and 6A RMS on-state current in a Surface Mount TO-252 (DPAK) package manufactured by Littelfuse Inc. This component is classified as Obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain functional compatibility while meeting the electrical and mechanical requirements of the original application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S2006DRP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• SCR Type: Standard Recovery
• Operating Temperature Range: -40°C to 125°C (minimum)
• Gate Trigger Voltage (Vgt) Max: ≤ 1.5V
• Gate Trigger Current (Igt) Max: ≤ 15mA
• On-State Voltage (Vtm) Max: ≤ 1.6V
• Hold Current (Ih) Max: ≤ 30mA

Voltage Rating Consideration: The S2006DRP operates at 200V off-state voltage. Substitute parts with equal or higher voltage ratings (400V, 600V) are electrically compatible and provide enhanced voltage margin. Parts with lower voltage ratings are not suitable.

Current Rating Consideration: The S2006DRP is rated for 6A RMS on-state current. Substitute parts with equal or higher current ratings maintain or exceed the original current handling capability. Parts with lower current ratings are not suitable.

Parameter Comparison

Engineering Selection Recommendations

S4006DRP (Littelfuse Inc., Active Status) The S4006DRP is a direct form-fit-function substitute with identical gate trigger parameters and on-state voltage characteristics. It provides a 200V voltage margin increase (400V vs. 200V) while maintaining all other electrical specifications. Product status is Active with full manufacturing support. RoHS3 compliance and MSL-1 rating match the original part. This substitute is suitable for applications where the higher voltage rating does not create design conflicts.

S6006DRP (Littelfuse Inc., Active Status) The S6006DRP maintains identical electrical characteristics to the S2006DRP with a 400V voltage margin increase (600V vs. 200V). All gate trigger, on-state voltage, and hold current parameters are equivalent. Product status is Active with established supply chain availability. RoHS3 compliance and MSL-1 rating are maintained. This substitute provides maximum voltage headroom for applications requiring enhanced overvoltage protection.

TN815-600B-TR (STMicroelectronics, Active Status, MFR Recommended) The TN815-600B-TR is a cross-manufacturer substitute from STMicroelectronics with enhanced electrical performance. It provides 600V off-state voltage rating and 8A RMS on-state current (vs. 6A), exceeding the original part's current capability. Gate trigger voltage is lower (1.3V vs. 1.5V), improving gate drive efficiency. Hold current is higher (40mA vs. 30mA) but remains within acceptable design margins. Package, mounting type, and operating temperature range are identical. Product status is Active with ROHS3 compliance. This substitute is recommended for applications requiring higher current capacity or improved gate drive characteristics.

Frequently Asked Questions (FAQ)

Q: Can the S4006DRP or S6006DRP be used as direct replacements for the S2006DRP? A: Yes. Both parts maintain identical gate trigger voltage, gate trigger current, on-state voltage, and hold current specifications. The higher voltage ratings (400V and 600V respectively) are electrically compatible with 200V applications and provide additional voltage margin. Package, mounting type, and operating temperature range are identical.

Q: What is the difference between the Littelfuse substitutes and the STMicroelectronics TN815-600B-TR? A: The TN815-600B-TR offers enhanced performance with 8A RMS on-state current (vs. 6A), lower gate trigger voltage (1.3V vs. 1.5V), and lower off-state leakage current (5µA vs. 10µA). It is a cross-manufacturer substitute from a different supplier. All parts maintain identical package, mounting type, and operating temperature specifications.

Q: Are all substitute parts available in the same packaging options? A: The S4006DRP is supplied in Cut Tape (CT) packaging. The S6006DRP is supplied in Tape & Reel (TR) packaging. The TN815-600B-TR is supplied in Cut Tape (CT) & Digi-Reel® packaging. All parts use the identical TO-252-3 DPAK physical package suitable for surface mount assembly.

Q: Do all substitute parts meet RoHS and MSL requirements? A: Yes. All substitute parts are ROHS3 compliant and rated MSL-1 (Unlimited moisture sensitivity level), matching the original S2006DRP specifications.

Q: Which substitute part should be selected for new designs? A: For new designs, select from the Active status parts: S4006DRP, S6006DRP, or TN815-600B-TR. All three are in active production with established supply chains. Selection depends on voltage rating requirements, current capacity needs, and supplier preference. The TN815-600B-TR is recommended where higher current capacity (8A vs. 6A) or improved gate drive efficiency (1.3V trigger voltage) provides design advantages.
