Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L6008D6TP are qualified based on the following criteria:

Electrical Compatibility Parameters:

• Triac Type: Logic - Sensitive Gate
• Voltage - Off State: 600 V
• Voltage - Gate Trigger (Vgt) (Max): 1.3 V
• Current - Gate Trigger (Igt) (Max): 5 mA
• Current - Hold (Ih) (Max): 10 mA
• Configuration: Single

Mechanical Compatibility Parameters:

• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute parts T405-600B, T405-600B-TR, and T405Q-600B-TR from STMicroelectronics meet these criteria. Note that substitute parts are rated for 4 A on-state current (lower than the 8 A rating of the L6008D6TP) and operate across an extended temperature range (-40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original L6008D6TP. The primary design consideration is the reduced on-state current rating of substitute parts (4 A versus 8 A). Selection should be based on circuit current requirements. T405-600B-TR and T405Q-600B-TR offer extended temperature operating range (-40°C ~ 125°C) compared to the L6008D6TP (-40°C ~ 110°C), providing additional thermal margin in applications requiring higher junction temperatures. Packaging format (Tube versus Cut Tape & Digi-Reel®) should align with procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can T405-600B, T405-600B-TR, or T405Q-600B-TR directly replace L6008D6TP in all applications?

A: Direct replacement is possible only if circuit design accommodates the 4 A on-state current rating of substitute parts. The L6008D6TP is rated for 8 A; substitute parts are rated for 4 A. Gate trigger voltage, gate trigger current, hold current, and off-state voltage are identical across all parts.

Q: What is the difference between T405-600B, T405-600B-TR, and T405Q-600B-TR?

A: All three parts share identical electrical specifications (600 V, 4 A, 1.3 V gate trigger). Differences are packaging format (Tube versus Cut Tape & Digi-Reel®) and non-repetitive surge current ratings (30A/31A for T405-600B and T405-600B-TR; 35A/38A for T405Q-600B-TR). Packaging selection depends on procurement and assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. L6008D6TP, T405-600B, T405-600B-TR, and T405Q-600B-TR are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the operating temperature difference between L6008D6TP and substitute parts?

A: L6008D6TP operates from -40°C to 110°C (TJ). Substitute parts operate from -40°C to 125°C (TJ), providing 15°C additional upper temperature margin.

Q: Are the packages physically identical?

A: Yes. All parts use TO-252-3, DPAK (2 Leads + Tab), SC-63 package with Surface Mount mounting type, ensuring PCB footprint compatibility.
