S6006VTP SCR 600V 6A TO-251 Equivalent & Substitute Parts

Part Overview

The S6006VTP is a standard recovery SCR (silicon-controlled rectifier) rated for 600V off-state voltage and 6A RMS on-state current, manufactured by Littelfuse Inc. in TO-251 (V-Pak/I-Pak) through-hole packaging. This component is active and ROHS3 compliant. Equivalent and substitute parts are identified when circuit designs require alternative sourcing, higher current ratings, different gate sensitivity characteristics, or alternative mounting technologies while maintaining electrical compatibility within the 600V voltage class.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the S6006VTP is based on the following criteria:

Voltage Compatibility: All substitute parts maintain the 600V off-state voltage rating, ensuring compatibility in circuits designed for this voltage class.

Current Rating Consideration: Substitute parts are grouped by on-state current capacity. Parts with equal or higher RMS current ratings (6A or greater) provide direct substitution capability. Parts with lower current ratings (4A) are listed as alternatives for reduced-load applications only.

Gate Sensitivity: The S6006VTP uses standard gate characteristics (Vgt 1.5V max, Igt 15mA max). Sensitive gate variants (Vgt 800mV max, Igt 75µA-200µA) offer lower gate drive requirements but maintain voltage and current compatibility.

Mounting and Package: Through-hole TO-251 (IPAK) packaging is the primary substitution criterion. Surface-mount alternatives (TO-252 DPAK) are listed separately as they require PCB redesign.

Recovery Type: Standard recovery and sensitive gate types are both listed, as both maintain the required electrical performance within the 600V class.

Parameter Comparison

Engineering Selection Recommendations

Direct Through-Hole Substitutes (Same Mounting): TN1215-600H and TS1220-600H are pin-compatible through-hole replacements in TO-251 (IPAK) packaging. Both maintain 600V voltage rating and exceed the 6A current requirement. TN1215-600H provides standard recovery characteristics matching the S6006VTP gate drive profile. TS1220-600H offers sensitive gate operation with reduced gate trigger voltage (800mV) and current (200µA), suitable for low-power gate drive circuits.

Current-Rated Alternative (Through-Hole): TS820-600H provides 8A RMS current capacity in the same TO-251 (IPAK) package with sensitive gate characteristics. This part is suitable for applications requiring higher current margin within the through-hole form factor.

Surface-Mount Alternative: MCR708A1G is a sensitive gate SCR in TO-252 (DPAK) surface-mount packaging. While electrically compatible at 600V, it requires PCB redesign and is rated for 4A RMS, making it suitable only for reduced-load applications. Operating temperature range is -40°C to 110°C, compared to 125°C maximum for through-hole variants.

Compliance: All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the S6006VTP.

Frequently Asked Questions (FAQ)

Q: Can TN1215-600H directly replace S6006VTP in the same circuit? A: Yes. TN1215-600H is pin-compatible in TO-251 (IPAK) packaging and maintains 600V voltage rating with standard recovery characteristics. The 12A RMS rating exceeds the 6A requirement, providing additional current margin.

Q: What is the difference between standard recovery and sensitive gate SCRs? A: Standard recovery SCRs (S6006VTP, TN1215-600H) require higher gate trigger voltage (1.3-1.5V) and current (15mA). Sensitive gate variants (TS1220-600H, TS820-600H, MCR708A1G) require lower gate trigger voltage (800mV) and minimal current (75-200µA), reducing gate drive circuit complexity and power consumption.

Q: Is MCR708A1G a suitable replacement for S6006VTP? A: MCR708A1G is electrically compatible at 600V but differs in three aspects: surface-mount TO-252 packaging (requires PCB redesign), 4A RMS current rating (below the 6A requirement), and -40°C to 110°C operating range (versus 125°C). Use only in reduced-load applications with PCB modification capability.

Q: Why does TS1220-600H have higher current rating than S6006VTP? A: TS1220-600H is rated for 12A RMS compared to S6006VTP at 6A RMS. Both maintain identical 600V voltage class and TO-251 (IPAK) packaging. The higher current rating provides design flexibility for applications with future current growth or margin requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. S6006VTP and all listed substitute parts (MCR708A1G, TN1215-600H, TS1220-600H, TS820-600H) are ROHS3 compliant and REACH unaffected.

Q: What is the temperature operating range difference between through-hole and surface-mount options? A: Through-hole variants (S6006VTP, TN1215-600H, TS1220-600H, TS820-600H) operate from -40°C to 125°C. Surface-mount MCR708A1G operates from -40°C to 110°C, a 15°C reduction in maximum temperature rating.
