Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S4010VTP are qualified based on the following criteria:

Fixed Parameters (Must Match):

• Voltage - Off State: 400 V
• Voltage - Gate Trigger (Vgt) (Max): 1.5 V
• Current - Gate Trigger (Igt) (Max): 15 mA
• Voltage - On State (Vtm) (Max): 1.6 V
• Current - Hold (Ih) (Max): 30 mA
• SCR Type: Standard Recovery
• Operating Temperature Range: -40°C to 125°C
• Package / Case: TO-251-3 Short Leads, IPak, TO-251AA
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed Variation):

• Current - On State (It (RMS)) (Max): 6 A to 10 A range
• Current - Off State (Max): 5 µA to 10 µA range

The S4006VTP and S4008VTP are parametric equivalents within the 400V SCR family, with reduced on-state current ratings suitable for lower current applications while maintaining identical gate trigger and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—S4010VTP, S4006VTP, and S4008VTP—maintain Active product status with ROHS3 compliance and identical gate trigger characteristics. Selection between these parts is determined by application current requirements:

• S4010VTP: 10 A RMS on-state current. Primary selection for maximum current capacity within the 400V class.
• S4008VTP: 8 A RMS on-state current. Suitable for applications requiring intermediate current handling with identical electrical characteristics.
• S4006VTP: 6 A RMS on-state current. Appropriate for lower current applications within the same voltage and trigger parameter envelope.

All parts share identical off-state voltage, gate trigger voltage, gate trigger current, on-state voltage, hold current, and operating temperature range. Substitution is valid when application current requirements do not exceed the substitute part's rated on-state current specification.

Frequently Asked Questions (FAQ)

Q: Can S4006VTP replace S4010VTP in any application? A: S4006VTP is a parametric equivalent only for applications requiring 6 A or less on-state current. The 400V off-state voltage, gate trigger characteristics, and thermal range are identical. If the application requires more than 6 A RMS, S4006VTP is not suitable.

Q: What is the difference between S4008VTP and S4010VTP? A: Both parts are 400V SCRs with identical gate trigger and on-state voltage specifications. The primary difference is on-state current rating: S4008VTP is rated for 8 A RMS while S4010VTP is rated for 10 A RMS. S4008VTP is suitable for applications requiring 8 A or less.

Q: Are all three parts pin-compatible? A: Yes. All three parts use TO-251-3 Short Leads packaging (IPak, TO-251AA) with identical pinout and mechanical dimensions, enabling direct board-level substitution.

Q: Do these parts have different surge current ratings? A: No. All three parts share identical non-repetitive surge current ratings of 83A (50Hz) and 100A (60Hz).

Q: Which part should be selected for new designs? A: Select based on application current requirements. S4010VTP provides maximum current capacity. S4008VTP and S4006VTP are appropriate for lower current applications. All three maintain identical compliance certifications and operating characteristics within their respective current ratings.
