Product details
Overview
T1630-600W from STMicroelectronics is a 16A snubberless triac in ISOWATT220AB package, rated for 600V repetitive peak off-state voltage (VDRM/VRRM), with 30mA maximum gate trigger current (IGT) and 500 V/µs critical dV/dt at 125°C. It delivers high commutation performance for inductive load switching in vacuum cleaners and heating regulation systems.
For engineers reviewing the T1630-600W datasheet, T1630-600W pinout, T1630-600W application, or T1630-600W equivalent, key selection criteria include RMS on-state current (16A @ Tc=80°C), non-repetitive surge rating (218A @ 60Hz/16.7ms), I²t fusing value (220 A²s), dI/dt capability (50 A/µs), and thermal resistance (Rth(j-c) = 3.1 °C/W).
Technical Context
This triac employs ST's Snubberless™ technology to enable reliable commutation without external snubbers under inductive loads. Its quadrant I/II/III operation supports phase-control AC switching, with guaranteed gate sensitivity (IGT ≤30 mA) and high noise immunity (dV/dt ≥500 V/µs at Tj=125°C).
The device features low on-state voltage (VTM ≤1.4 V @ 22.5A, 25°C) and dynamic resistance (Rd ≤20 mΩ @ 125°C), enabling efficient power handling. Junction-to-case thermal resistance of 3.1 °C/W supports direct heatsink mounting for sustained 16A RMS conduction at 80°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A - Sustained RMS current at Tc=80°C; defines continuous load-handling capacity in mains-powered appliances |
| VDRM / VRRM | 600 V - Peak repetitive off-state voltage; ensures safe blocking across 230VAC mains with margin |
| IGT (max) | 30 mA - Maximum gate trigger current required; determines driver circuit strength and microcontroller GPIO compatibility |
| dV/dt (min) | 500 V/µs - Minimum rate of rise of off-state voltage before false turn-on; enables robust operation with inductive transients |
| I²t (fusing) | 220 A²s - Thermal energy limit before fuse failure; used for coordination with fast-acting fuses in protection design |
| Rth(j-c) | 3.1 °C/W - Junction-to-case thermal resistance; defines heatsink sizing requirement for thermal management |
| ITSM (60Hz) | 218 A - Non-repetitive surge current for 16.7ms half-cycle; supports motor startup and transient overload tolerance |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate triggering; connected to load return or neutral side in standard phase-control topology |
| A2 (MT2) | Main Terminal 2 | High-side main current path; connected to AC line input; carries full load current in both half-cycles |
| G | Gate | Control electrode; triggers conduction when IGT ≥30 mA applied between G and A1; polarity-sensitive in Quadrants I/II/III |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA16-600BWRG | Same 16A/600V rating but standard (non-snubberless) design; lower dV/dt (250 V/µs); TO-220AB package | Requires external snubber for inductive loads; higher gate drive demand (IGT ≤50 mA) | Select only if cost sensitivity outweighs snubber BOM and layout complexity |
| MAC16A6YG | 16A/600V snubberless triac; same ISOWATT220AB package; IGT ≤35 mA; dV/dt ≥500 V/µs; not UL-recognized | Lacks UL E81734 certification; identical electrical performance otherwise | Prefer when UL compliance is not required and alternate sourcing is needed |
Compared with BTA16-600BWRG and MAC16A6YG, the T1630-600W uniquely combines UL recognition, guaranteed 500 V/µs dV/dt, and 30 mA IGT in a single-source qualified part-reducing qualification effort for certified appliance designs.

FAQ
What is the maximum allowable case temperature for continuous 16A RMS operation?
The datasheet specifies IT(RMS) = 16 A at Tc = 80°C. Operation above this temperature requires derating per Fig. 2: at Tc = 100°C, RMS current must be reduced to approximately 12 A. Exceeding 80°C without derating risks thermal runaway due to positive temperature coefficient of on-state voltage.
Can T1630-600W replace T1620-600W directly in an existing design?
Yes, it is a direct replacement with identical package, voltage rating, and thermal characteristics. The only difference is higher gate trigger current (30 mA vs. 20 mA), which may require verifying gate driver capability-especially in marginal or aging circuits where gate drive margin is tight.
Does T1630-600W support bidirectional triggering in all four quadrants?
No-it is specified and characterized for Quadrants I, II, and III only. Quadrant IV triggering (A2 negative, G positive relative to A1) is not guaranteed per datasheet test conditions and should be avoided in production designs.
What is the recommended heatsink interface material for ISOWATT220AB mounting?
ST recommends using a thermally conductive insulating pad (e.g., silicone rubber with ceramic filler) or thermal grease with dielectric film, given the insulated tab. Mechanical torque must stay within 0.55–0.70 m·N to avoid cracking the package or compromising thermal contact integrity.
