Product details

Overview

T1010H-6T from STMicroelectronics is a high-temperature, logic-level sensitive TRIAC rated for 10 A RMS on-state current and 600 V blocking voltage, designed for AC load switching in appliance and industrial control systems. It features gate trigger current ≤10 mA, 150 °C maximum junction temperature, and optimized thermal resistance (R_th(j-c) = 1.50 °C/W) for compact heatsink integration.

For engineers reviewing the T1010H-6T datasheet, T1010H-6T pinout, T1010H-6T application, or T1010H-6T equivalent, key selection criteria include gate sensitivity at elevated temperature, dV/dt immunity up to 75 V/µs at T_j = 150 °C, commutation robustness, on-state voltage drop (V_T ≤ 1.5 V), and TO-220AB package thermal performance.

Technical Context

The T1010H-6T operates as a bidirectional thyristor with three-quadrant triggering capability (I, II, III), enabling reliable turn-on under low-gate-drive conditions across both polarities of A2 relative to A1. Its logic-level gate design ensures compatibility with microcontroller I/O pins without external amplification.

Engineered for high-temperature reliability, it maintains specified commutation margins and noise immunity up to T_j = 150 °C, supported by a low dynamic resistance (R_d ≤ 41 mΩ) and threshold voltage (V_t0 ≤ 0.80 V) at maximum junction temperature - critical for stable operation in thermally constrained environments.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar TRIAC-based AC switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTB10-600CW	Same IT(RMS) and VDRM, but IGT max = 15 mA; lower dV/dt immunity (50 V/µs @ Tj=125°C); TO-220 insulated package	Requires higher gate drive strength; less suitable for thermally aggressive or high-EMI environments	Select when gate drive margin exceeds 15 mA and ambient temperature remains ≤110 °C
Q6010LH4	10 A/600 V, IGT max = 10 mA, but rated only to Tj = 125 °C; higher Rth(j-c) = 2.0 °C/W	Thermal derating required above 110 °C ambient; larger heatsink needed for same power dissipation	Select for cost-sensitive designs where peak junction temperature stays below 125 °C

Compared with BTB10-600CW and Q6010LH4, the T1010H-6T provides superior high-temperature stability (150 °C Tj), lower thermal resistance, and higher dV/dt immunity - making it optimal for space-constrained, thermally demanding appliance and industrial control modules.

FAQ

What is the maximum junction temperature rating for the T1010H-6T?

The T1010H-6T is rated for continuous operation up to a maximum junction temperature (T_j) of 150 °C, as confirmed in Table 2 of ST's Doc ID 15715 Rev 1. This rating is validated across all absolute maximum parameters including I_TSM, dI/dt, and dV/dt, enabling use in sealed or high-ambient-temperature applications without thermal derating.

Does the T1010H-6T support three-quadrant triggering?

Yes, the T1010H-6T supports triggering in Quadrants I, II, and III, as explicitly stated in Table 3 (Electrical Characteristics) and confirmed by test conditions specifying "I – II – III" for I_GT, V_GT, and V_GD. This allows flexible gate drive polarity configurations and improves noise immunity in AC phase-control circuits.

What is the thermal resistance from junction to case (Rth(j-c)) for the TO-220AB package?

The junction-to-case thermal resistance (R_th(j-c)) for the T1010H-6T in TO-220AB package is 1.50 °C/W, as specified in Table 5 of the official datasheet. This value applies under AC conditions and is measured with the case mounted to a heatsink using recommended torque (0.4–0.6 N·m).

Is the T1010H-6T RoHS compliant and halogen-free?

Yes, the T1010H-6T is RoHS compliant per Directive 2002/95/EC and carries ECOPACK® certification. The package uses halogen-free, lead-free epoxy meeting UL94 V0 flammability rating, as documented in Section 3 ("Package information") of ST's datasheet Doc ID 15715 Rev 1.
