Product details
Overview
T1650-600G-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 50 mA gate trigger current (IGT), 1000 V/µs critical dV/dt (Tj = 125 °C), and insulated thermal performance with Rth(j-c) = 1.2 °C/W - enabling robust phase-angle control in motor speed controllers without external snubbers.
For engineers reviewing the T1650-600G-TR datasheet, T1650-600G-TR pinout, T1650-600G-TR application, or T1650-600G-TR equivalent, key selection criteria include snubberless commutation capability for inductive loads, D²PAK thermal resistance, gate sensitivity (50 mA IGT), and UL1557-certified insulation integrity at 2500 VRMS.
Technical Context
This triac operates in three quadrants (I, II, III) with optimized turn-on dynamics for inductive load commutation. Its internal ceramic pad enables 2500 VRMS insulated tab rating and eliminates need for external snubber networks in motor and relay applications.
It delivers 16 A RMS on-state current at Tc = 100 °C in D²PAK, supported by 50 A/µs critical di/dt and 1000 V/µs dV/dt immunity at 125 °C junction temperature - ensuring reliable zero-crossing and phase-control operation under high-noise industrial AC line conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A - Sustains continuous 16 A AC load current at 100 °C case temperature in D²PAK package. |
| VDRM / VRRM | 600 V - Blocks 600 V peak reverse/repetitive off-state voltage, suitable for 230 VAC mains with safety margin. |
| IGT (Snubberless) | 50 mA max - Gate trigger current requirement for reliable turn-on under worst-case temperature and voltage conditions. |
| (dV/dt)c | 1000 V/µs min @ Tj = 125 °C - Enables stable operation without false triggering in high-dV/dt inductive switching environments. |
| Rth(j-c) | 1.2 °C/W - Junction-to-case thermal resistance allows efficient heatsinking in compact D²PAK surface-mount layouts. |
| IH | 50 mA max - Holding current ensures latched conduction persists through low-current portions of AC waveform. |
| VT | 1.55 V max @ 22.5 A - Low on-state voltage minimizes power dissipation and thermal stress during conduction. |
Pinout & Package
Package: D²PAK (TO-263AB), surface-mount, thermally enhanced with exposed drain pad for direct PCB copper thermal coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate triggering; forms current path with A2 during conduction. |
| A2 (MT2) | Main Terminal 2 | High-side AC line connection; carries full load current with A1; electrically isolated from tab. |
| G | Gate | Control input requiring ≥50 mA pulse to initiate conduction in quadrants I, II, and III. |
| Tab (Drain) | Thermal & Electrical Reference | Exposed metal pad tied internally to A2; must be connected to PCB copper pour for thermal management and electrical isolation compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ commutation | Enables direct drive of inductive loads (e.g., universal motors) without external RC snubber, reducing BOM count and board space. |
| UL1557-certified insulation | 2500 VRMS reinforced insulation between tab and terminals meets safety standards for Class I appliances and industrial controls. |
| D²PAK thermal performance | 1.2 °C/W junction-to-case resistance supports 16 A RMS operation with minimal heatsink area on FR4 PCB. |
| High dV/dt immunity | 1000 V/µs minimum at 125 °C prevents false triggering in noisy EMI environments typical of motor drives and dimmers. |
| Three-quadrant operation | Eliminates gate sensitivity in quadrant IV, improving noise immunity and simplifying gate driver design for phase-control applications. |
Applications
| Universal Motor Speed Control | Industrial Static Relay |

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 |
|---|---|---|---|
| T1635-600G-TR | 35 mA IGT, 500 V/µs dV/dt (Tj = 125 °C), same D²PAK package and 16 A/600 V rating. | Lower gate drive requirement suits microcontroller GPIOs with limited current drive; reduced dV/dt margin for less noisy loads. | Select when gate drive capability is constrained and load inductance is moderate (e.g., fan motors). |
| BTA16-600BW | TO-220AB insulated package, 50 mA IGT, 2500 VRMS isolation, Rth(j-c) = 2.1 °C/W. | Through-hole mounting with higher thermal resistance; requires mechanical heatsink but offers easier manual assembly and field replacement. | Select for prototyping, repairable designs, or where surface-mount thermal constraints prevent D²PAK use. |
Compared with T1635-600G-TR, T1650-600G-TR provides higher dV/dt immunity for harsher EMI environments; compared with BTA16-600BW, it offers superior thermal efficiency in automated SMT production but requires careful PCB copper layout for thermal management.

FAQ
What is the maximum junction temperature for continuous operation?
The T1650-600G-TR has an operating junction temperature range of –40 °C to +125 °C. For sustained 16 A RMS conduction, case temperature must not exceed 100 °C per datasheet derating curves - requiring adequate PCB copper area (≥10 cm² recommended) or heatsink attachment to the D²PAK tab.
Does this triac require a heat sink in typical applications?
A dedicated heat sink is not mandatory if PCB thermal design meets specifications: ≥10 cm² of 35 µm copper on inner/outer layers beneath the D²PAK tab, with thermal vias. Under full 16 A load at 25 °C ambient, junction temperature rises ~60 °C above case - making board-level copper the primary thermal path.
Can T1650-600G-TR replace BTA16-600BW in existing through-hole designs?
No - T1650-600G-TR uses D²PAK surface-mount packaging and cannot be drop-in replaced in TO-220AB footprints. Mechanical, thermal, and soldering processes differ fundamentally. A full PCB redesign is required to migrate from BTA16-600BW to T1650-600G-TR.
Is the insulated tab rated for functional or reinforced insulation?
The D²PAK package does not feature an insulated tab - only TO-220AB Ins. variants (e.g., BTA16-600BW) provide 2500 VRMS reinforced insulation. T1650-600G-TR's tab is electrically connected to A2 and must be isolated via PCB layout or external insulation per end-equipment safety requirements.
