STMicroelectronics T1610-800G-TR

Overview

T1610-800G-TR from STMicroelectronics is a 16 A, 800 V Snubberless™ triac in D²PAK surface-mount package, designed for high-commutation AC mains switching in inductive loads. It features 10 mA gate trigger current (IGT), 40 V/µs minimum dV/dt at 125 °C, and insulated thermal performance with Rth(j-c) = 1.2 °C/W - enabling reliable phase-angle control in motor speed controllers and static relays without external snubbers.

For engineers reviewing the T1610-800G-TR datasheet, T1610-800G-TR pinout, T1610-800G-TR application, or T1610-800G-TR equivalent, key selection criteria include snubberless commutation capability for inductive loads, D²PAK thermal resistance, 2500 VRMS isolation rating (via internal ceramic pad), and compatibility with zero-crossing or phase-control driver circuits in industrial and appliance designs.

Technical Context

This triac operates in three quadrants (I, II, III) with logic-level gate sensitivity (10 mA max IGT), enabling direct drive from microcontrollers or optocouplers without buffer stages. Its Snubberless™ architecture eliminates need for RC snubber networks by sustaining high critical rate of rise of off-state voltage (dV/dt ≥ 40 V/µs) and high commutation robustness under inductive load turn-off stress.

The device integrates an internal ceramic insulation pad rated at 2500 VRMS between the tab and die, meeting UL1557 (file E81734) for reinforced isolation. Thermal design leverages D²PAK's low junction-to-case resistance (1.2 °C/W) and supports PCB copper area optimization per Figure 12 - critical for sustained 16 A RMS conduction at Tc ≤ 100 °C.

FAQ

Is the T1610-800G-TR RoHS and REACH compliant?

Yes. The device meets RoHS Directive 2002/95/EC and REACH SVHC requirements. It uses halogen-free epoxy and lead-free terminations qualified for Pb-free reflow soldering (JEDEC J-STD-020). Full compliance documentation is available upon request from Aetrix Electronics.

What is the maximum allowable case temperature for continuous 16 A operation?

The datasheet specifies IT(RMS) = 16 A at Tc = 100 °C for the D²PAK package. Operation above this temperature requires derating per Figure 3; at Tc = 110 °C, maximum RMS current drops to approximately 13.5 A. Heatsink design must maintain tab temperature ≤100 °C under worst-case ambient and airflow conditions.

Does the insulated tab require external isolation when mounted to a heatsink?

No - the internal ceramic insulation provides 2500 VRMS isolation between the die and tab, satisfying UL1557 (file E81734). However, the heatsink itself must be electrically isolated from system ground if connected to other non-isolated circuitry, as the tab is electrically tied to MT2.

Can the T1610-800G-TR replace a BTA16-800B in an existing TO-220AB design?

Electrically yes - identical voltage/current/specs - but mechanically no: D²PAK is surface-mount while TO-220AB is through-hole. A PCB redesign is required. For drop-in replacement, use BTA16-800SW (same 10 mA IGT, insulated TO-220AB) or BTB16-800SW (non-insulated variant).
