STMicroelectronics T2035H-600IRG

Overview

T2035H-600IRG from STMicroelectronics is a snubberless, high-temperature 20 A, 600 V triac in insulated TO-220AB package, designed for reliable phase-control switching of inductive loads at junction temperatures up to 150 °C. It delivers 35 mA gate trigger current, 1.3 V max gate trigger voltage, and 8.9 A/ms critical di/dt without snubber, enabling robust motor control in hot appliances.

For engineers reviewing the T2035H-600IRG datasheet, T2035H-600IRG pinout, T2035H-600IRG application, or T2035H-600IRG equivalent, key selection criteria include thermal performance at 150 °C, snubberless commutation capability, gate sensitivity (Q1), and insulated package suitability for high-voltage isolation in cooking and heating systems.

Technical Context

This triac operates in all four quadrants with symmetrical triggering behavior and is optimized for universal motor and resistive-inductive load control. Its Snubberless™ architecture eliminates external snubbers by sustaining ≥300 V/µs dV/dt at 150 °C and supporting ≥8.9 A/ms (dI/dt)_c under snubberless conditions.

Thermal design is enabled by R_th(j–c) = 1.9 °C/W (insulated TO-220AB) and low on-state resistance (R_D = 21 mΩ at 150 °C), allowing stable 20 A RMS conduction at case temperatures up to 105 °C without derating.

Key Specifications

Pinout & Package

Insulated TO-220AB package (3-terminal, metal tab isolated from A2). Mounting surface electrically isolated per JEDEC TO-220AB Ins standard; tab serves as A2 terminal with creepage/clearance enhanced for 2500 V_RMS isolation.

FAQ

Is T2035H-600IRG RoHS-compliant and lead-free?

Yes. T2035H-600IRG is manufactured in ST's ECOPACK®-compliant insulated TO-220AB package with lead-free second-level interconnect, meeting RoHS Directive 2011/65/EU and JEDEC JESD97 marking requirements. The inner box label confirms Pb-free status and soldering profile limits.

Can T2035H-600IRG replace non-insulated triacs in existing designs?

Only with mechanical and safety review. The insulated TO-220AB package has identical outline but requires verification of creepage/clearance, mounting hardware (e.g., insulating bushings), and thermal interface (R_th(j–c) = 1.9 °C/W vs. 1.0 °C/W for non-insulated). Electrical substitution is valid; mechanical redesign may be needed.

What is the minimum gate trigger pulse width required?

The datasheet specifies I_GM = 4 A peak gate current for t_p = 20 µs at T_j = 150 °C. For reliable triggering at room temperature, a 100 µs pulse at ≥35 mA is sufficient. Shorter pulses require proportionally higher current to maintain charge transfer (Q_G ≈ I_G × t_p).

Does T2035H-600IRG support zero-crossing switching?

No. As a standard triac, it conducts bidirectionally once triggered but lacks integrated zero-cross detection. Zero-crossing operation requires external circuitry (e.g., optocoupler with ZCD output) to time gate pulses to voltage zero crossings-enabling EMI reduction and inrush limiting.
