QJ6006DH3TP Equivalent & Substitute Parts

Part Overview

The QJ6006DH3TP is an Alternistor-class TRIAC manufactured by Littelfuse Inc., rated for 600 V off-state voltage and 6 A on-state current in a surface mount TO-252 (DPAK) package. This snubberless design is actively produced and RoHS3 compliant. Substitute parts are identified based on matching electrical ratings, package compatibility, and operational parameters that permit direct circuit replacement.

Substitute Part Grouping Explanation

Substitution eligibility for the QJ6006DH3TP is determined by the following criteria:

Voltage Rating: Off-state voltage must be 600 V or higher
Current Rating: On-state current (It (RMS)) must meet or exceed 6 A
Gate Trigger Parameters: Vgt and Igt must be within acceptable circuit operating ranges
Package Compatibility: TO-252-3 DPAK package with identical pinout
Mounting Type: Surface mount configuration
Compliance: RoHS status and regulatory alignment

The three identified substitutes (BT137S-600,118; BT137S-600E,118; BTA208S-600E,118) meet these criteria with on-state current ratings of 8 A, providing margin above the 6 A requirement. All maintain 600 V voltage rating, compatible DPAK packaging, and active product status.

Engineering Selection Recommendations

All three substitute parts are actively produced and RoHS compliant, meeting regulatory requirements equivalent to the QJ6006DH3TP. Selection among substitutes depends on circuit-specific gate trigger characteristics:

BT137S-600,118: Standard TRIAC with 1 V gate trigger voltage and 70 mA gate trigger current. Suitable for applications requiring lower gate trigger voltage.

BT137S-600E,118: Logic-sensitive gate TRIAC with 1.5 V gate trigger voltage and 10 mA gate trigger current, matching the QJ6006DH3TP gate trigger current specification. Recommended for direct replacement in circuits designed for the original part's gate characteristics.

BTA208S-600E,118: Logic-sensitive gate TRIAC with 1.5 V gate trigger voltage, 10 mA gate trigger current, and 25 mA hold current matching the QJ6006DH3TP hold current specification. Provides parameter alignment across multiple gate and hold current ratings.

All substitutes provide 8 A on-state current, exceeding the 6 A requirement, and maintain identical TO-252-3 DPAK packaging for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can BT137S-600,118 replace QJ6006DH3TP in all applications?

A: BT137S-600,118 is electrically compatible based on voltage and current ratings. However, its 70 mA gate trigger current differs from the QJ6006DH3TP specification of 10 mA. Circuit gate drive requirements must be evaluated before substitution.

Q: What is the difference between BT137S-600E,118 and BTA208S-600E,118?

A: Both are logic-sensitive gate TRIACs with identical voltage ratings and gate trigger parameters. BTA208S-600E,118 specifies 25 mA hold current, matching the QJ6006DH3TP, while BT137S-600E,118 specifies 20 mA. Hold current differences may affect circuit behavior in low-current holding conditions.

Q: Are all substitutes available in the same package?

A: Yes. All substitute parts use TO-252-3 DPAK (2 Leads + Tab) SC-63 packaging, identical to the QJ6006DH3TP, enabling direct PCB placement without layout modification.

Q: Do substitute parts meet the same temperature operating range?

A: The QJ6006DH3TP operates from -40°C to 150°C. Substitute parts specify 125°C maximum junction temperature. Applications requiring operation above 125°C require thermal analysis or alternative part selection.

Q: Are all parts RoHS compliant?

A: Yes. QJ6006DH3TP is RoHS3 compliant. All substitute parts are RoHS compliant, meeting regulatory requirements for restricted substance elimination.
