S6006V SCR 600V 6A Equivalent & Substitute Parts

Part Overview

The S6006V is a standard recovery SCR (silicon controlled rectifier) rated for 600V off-state voltage and 6A RMS current, manufactured by Littelfuse Inc. in a TO-251 through-hole package. This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing applications and new designs requiring similar electrical performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S6006V is determined by the following criteria:

Mandatory Compatibility Parameters:

• Voltage - Off State: 600 V (exact match required)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: TO-251-3 IPAK (pin-compatible form factor)
• RoHS Status: ROHS3 Compliant (regulatory alignment)

Performance Parameters (allowable variation):

• Current - On State (It RMS): Equal to or greater than 6 A
• Voltage - On State (Vtm Max): Equal to or less than 1.6 V
• Voltage - Gate Trigger (Vgt Max): Equal to or less than 1.5 V
• Current - Gate Trigger (Igt Max): Equal to or less than 15 mA
• SCR Type: Standard Recovery or Sensitive Gate (both acceptable for 600V applications)
• Operating Temperature: Minimum -40°C, maximum 125°C or higher

Substitute parts meeting these criteria maintain electrical and mechanical compatibility with the original S6006V design.

Parameter Comparison

Engineering Selection Recommendations

Direct Through-Hole Substitutes (Pin-Compatible):

TN1215-600H and TS1220-600H are through-hole TO-251 IPAK packages with 600V rating and active product status. Both exceed the 6A RMS requirement with 12A capability. TN1215-600H maintains standard recovery characteristics matching the original S6006V type. TS1220-600H uses sensitive gate technology with lower gate trigger voltage and current, suitable for applications requiring reduced gate drive requirements. Both support the full -40°C to 125°C operating range.

TS820-600H provides 8A RMS current in the same TO-251 IPAK package with sensitive gate characteristics and active status. This part bridges the current rating between S6006V (6A) and higher-current alternatives.

Surface Mount Alternative:

MCR708A1G is a Littelfuse sensitive gate SCR in TO-252 DPAK surface mount package. While electrically compatible at 600V, it requires PCB layout modification due to different mounting technology. Current rating is 4A RMS, below the original 6A specification. Operating temperature range is -40°C to 110°C, 15°C lower than the original part. This option is suitable only for new designs with surface mount capability and current requirements not exceeding 4A.

All substitute parts carry ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), matching the original part's regulatory and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can I use MCR708A1G as a direct replacement for S6006V?

A: MCR708A1G is not a direct replacement. While both are 600V SCRs with ROHS3 compliance, MCR708A1G uses surface mount TO-252 DPAK packaging versus the through-hole TO-251 IPAK of S6006V. Additionally, MCR708A1G is rated for 4A RMS, below the 6A RMS of S6006V. This part requires PCB redesign and is suitable only for new designs with lower current requirements.

Q: Which substitute maintains the closest electrical match to S6006V?

A: TN1215-600H provides the closest electrical match. Both S6006V and TN1215-600H are standard recovery SCRs with 600V rating, 1.6V maximum on-state voltage, 15mA maximum gate trigger current, and -40°C to 125°C operating range. TN1215-600H exceeds the 6A RMS requirement with 12A capability and maintains through-hole TO-251 IPAK packaging for direct PCB compatibility.

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

A: Standard recovery SCRs (S6006V, TN1215-600H) require higher gate trigger voltage and current for activation. Sensitive gate SCRs (TS1220-600H, TS820-600H, MCR708A1G) activate with lower gate drive requirements, reducing gate circuit complexity. Both types are suitable for 600V applications; selection depends on gate drive circuit design.

Q: Can I use TS1220-600H in place of S6006V if my application only requires 6A?

A: Yes. TS1220-600H is rated for 12A RMS and operates within the same voltage and temperature specifications as S6006V. The higher current rating provides design margin without affecting performance in 6A applications. Both use through-hole TO-251 IPAK packaging for direct PCB compatibility.

Q: What is the temperature operating range difference between S6006V and MCR708A1G?

A: S6006V operates from -40°C to 125°C, while MCR708A1G operates from -40°C to 110°C. The 15°C difference in maximum temperature may be significant for high-temperature applications. For designs requiring full -40°C to 125°C operation, use through-hole alternatives TN1215-600H, TS1220-600H, or TS820-600H.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (MCR708A1G, TN1215-600H, TS1220-600H, TS820-600H) carry ROHS3 compliance matching the original S6006V specification.
