STMicroelectronics T1610-600G-TR

Overview

T1610-600G-TR from STMicroelectronics is a 16 A, 600 V Snubberless™ triac in D²PAK package, designed for high-commutation AC mains switching in inductive loads. It features 10 mA gate trigger current (IGT), 2500 VRMS insulated tab, and 40 V/µs dV/dt rating at 125 °C - enabling reliable phase-angle control in motor speed controllers without external snubbers.

For engineers reviewing the T1610-600G-TR datasheet, T1610-600G-TR pinout, T1610-600G-TR application, or T1610-600G-TR equivalent, key selection criteria include insulated-tab safety compliance (UL1557), snubberless commutation performance on inductive loads, thermal resistance (Rth(j-c) = 1.2 °C/W), and tape-and-reel availability for automated assembly.

Technical Context

This triac operates in three quadrants (I, II, III) with logic-level gate sensitivity (IGT ≤ 10 mA), enabling direct drive from microcontrollers or optocouplers without buffer stages. Its Snubberless™ architecture eliminates need for RC snubber networks when switching inductive loads like universal motors or solenoids.

Thermal design is supported by low junction-to-case resistance (1.2 °C/W) and an insulated D²PAK package rated for 2500 VRMS isolation. The device sustains 160 A non-repetitive surge current (tp = 20 ms, 50 Hz) and maintains stable latching (IL ≤ 25 mA) and holding (IH ≤ 15 mA) across –40 to +125 °C junction temperature range.

FAQ

Is T1610-600G-TR compatible with zero-crossing optocouplers like MOC3041?

Yes - its 10 mA maximum gate trigger current (IGT) is fully compatible with standard zero-crossing optocouplers such as MOC3041 (rated for 15 mA output). The device triggers reliably within 1–2 µs after optocoupler turn-on, supporting precise phase-angle control without external gate resistors or buffers.

What is the maximum recommended heatsink temperature for continuous 16 A operation?

For continuous 16 A RMS operation, case temperature (Tc) must not exceed 100 °C per datasheet absolute maximum ratings. With Rth(j-c) = 1.2 °C/W and max. junction temperature of 125 °C, the heatsink must maintain Tc ≤ 100 °C - requiring thermal interface material and heatsink design that limit total Rth(c-sink) to ≤ 1.56 °C/W at ambient ≤ 50 °C.

Does the insulated tab require electrical isolation from the PCB ground plane?

No - the insulated tab is electrically isolated (2500 VRMS) from all internal terminals (A1, A2, G), so it may be directly bolted to a grounded metal heatsink or chassis without additional insulating hardware. However, the PCB copper pour beneath the tab must remain unconnected to any net to preserve isolation integrity.

Can T1610-600G-TR replace BTA16-600BWRG in existing TO-220AB designs?

Not as a drop-in replacement - T1610-600G-TR uses D²PAK surface-mount packaging versus TO-220AB through-hole. While electrical specs align closely (same IGT, VDRM, IT(RMS)), mechanical redesign is required for footprint, soldering profile, and thermal interface. For retrofit, BTA16-600SW (TO-220AB insulated, 10 mA IGT) is the functionally matched through-hole alternative.
