S2006DS3TP Equivalent & Substitute Parts

Part Overview

The S2006DS3TP is a Sensitive Gate SCR (Silicon Controlled Rectifier) rated for 200V off-state voltage with 6A RMS current capacity in a surface mount TO-252 (DPAK) package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts maintain identical gate trigger characteristics, on-state performance, and package compatibility while offering higher voltage ratings and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S2006DS3TP are selected based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant across all substitutes:

• SCR Type: Sensitive Gate
• Voltage - Gate Trigger (Vgt) (Max): 800 mV
• Current - Gate Trigger (Igt) (Max): 500 µA
• Voltage - On State (Vtm) (Max): 1.6 V
• Current - On State (It (RMS)) (Max): 6 A
• Current - Hold (Ih) (Max): 8 mA
• Operating Temperature: -40°C ~ 110°C
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The primary difference in substitute parts is the off-state voltage rating, which is higher than the original part. This allows for operation in higher voltage applications while maintaining all other electrical and thermal characteristics. Both substitute parts are manufactured by Littelfuse Inc. and carry active product status.

Parameter Comparison

Engineering Selection Recommendations

The S2006DS3TP is obsolete and no longer in active production. Both substitute parts—S4006DS3TP and S6006DS3TP—are active products from Littelfuse Inc. with identical gate trigger, on-state, and hold current specifications. Both substitutes maintain ROHS3 compliance and MSL Level 1 rating.

Selection between S4006DS3TP (400V) and S6006DS3TP (600V) depends on the maximum off-state voltage requirement of the application circuit. Both parts are electrically and mechanically interchangeable with the S2006DS3TP for gate drive and current handling characteristics. The higher voltage rating of the substitute parts provides design margin for applications operating near or at the original 200V specification.

Frequently Asked Questions (FAQ)

Q: Can S4006DS3TP or S6006DS3TP directly replace S2006DS3TP in existing designs?

A: Yes. Both substitute parts maintain identical gate trigger voltage (800 mV max), gate trigger current (500 µA max), on-state voltage (1.6 V max), RMS current rating (6 A), hold current (8 mA max), operating temperature range (-40°C to 110°C), and TO-252 DPAK package configuration. The higher off-state voltage ratings do not affect compatibility in circuits designed for 200V operation.

Q: What is the difference between S4006DS3TP and S6006DS3TP?

A: The primary difference is the off-state voltage rating: S4006DS3TP is rated for 400V, while S6006DS3TP is rated for 600V. All other electrical parameters, including gate characteristics, on-state performance, current ratings, and thermal specifications, are identical. Package and mounting type are identical.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts are ROHS3 compliant with MSL Level 1 rating. The S2006DS3TP is obsolete, while both S4006DS3TP and S6006DS3TP carry active product status from Littelfuse Inc.

Q: Does the higher voltage rating of substitute parts affect circuit performance?

A: No. The higher off-state voltage rating of substitute parts does not degrade performance in applications designed for lower voltages. The gate trigger characteristics, on-state voltage drop, and current handling remain identical, ensuring equivalent circuit behavior.

Q: Are packaging and lead configurations identical?

A: Yes. All three parts use the TO-252-3 DPAK (2 Leads + Tab) surface mount package with SC-63 case designation. PCB footprints and soldering procedures are identical.
