Product details
Overview
T1620-600W from STMicroelectronics is a 16A snubberless triac in ISOWATT220AB package, rated for 600V repetitive peak off-state voltage (VDRM/VRRM), with 20mA gate trigger current (IGT) and 50A/µs critical dI/dt. It delivers high commutation performance for inductive AC loads such as vacuum cleaner motor controls and heating regulation circuits.
For engineers reviewing the T1620-600W datasheet, T1620-600W pinout, T1620-600W application, or T1620-600W equivalent, key selection criteria include RMS on-state current (16A @ Tc=80°C), surge capability (200A @ 50Hz), dV/dt immunity (300V/µs min), and thermal resistance (Rth(j-c) = 3.1°C/W).
Technical Context
This triac uses ST's proprietary Snubberless™ technology to enable reliable commutation without external snubbers, especially under inductive load conditions where rapid current decay induces high reapplied dV/dt. Its design supports quadrant I, II, and III triggering with guaranteed IGT ≤20mA and dV/dt ≥300V/µs at Tj=125°C.
It features low on-state voltage (VTM ≤1.4V @ 22.5A, 25°C) and dynamic resistance (Rd ≤20mΩ @ 125°C), enabling efficient power handling. The device operates across -40°C to +125°C junction temperature and meets UL E81734 safety certification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar snubberless triac applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA16-600BWRG | Same 16A/600V rating but higher IGT (≤50mA); TO-220AB package without insulated tab | Lacks reinforced insulation; requires isolated mounting hardware for safety-critical mains isolation | Prefer when cost sensitivity outweighs insulation requirements and heatsink isolation is managed externally |
| Q6016LH4 | 16A/600V, 25mA IGT, but lower dV/dt (200V/µs) and no UL certification | Not suitable for UL-mandated end equipment; limited commutation robustness on highly inductive loads | Select only for non-certified consumer products where gate drive margin and surge immunity are less critical |
Compared with BTA16-600BWRG and Q6016LH4, T1620-600W provides superior insulation integrity, higher dV/dt immunity (300V/µs), and UL certification-making it the preferred choice for certified appliances and industrial controls requiring snubberless reliability.

FAQ
What is the maximum allowable case temperature for continuous 16A operation?
The datasheet specifies IT(RMS) = 16A at Tc = 80°C. Operation above this temperature requires derating per Figure 2: at Tc = 100°C, maximum RMS current drops to ~12.5A. Exceeding 80°C without thermal margin risks exceeding 125°C junction limit and premature failure.
Can T1620-600W replace a standard triac in an existing snubber-equipped design?
Yes - its Snubberless™ architecture allows direct replacement without removing the snubber, though the snubber may be omitted after validation. Removing it reduces component count and improves reliability, provided dV/dt and commutation margins remain sufficient per actual load characteristics.
Is the metal tab electrically isolated from the A2 terminal?
No - the metal tab is internally connected to A2 and serves as both heatsink interface and current-carrying terminal. Electrical isolation must be achieved externally using insulating washers or pads if A2 is not at chassis ground potential.
Does T1620-600W support gate triggering in all four quadrants?
It supports triggering in quadrants I, II, and III as specified in the electrical characteristics table. Quadrant IV triggering is not characterized or guaranteed - gate-to-A1 voltage polarity must avoid negative VGD beyond -0.2V to prevent damage or unreliable turn-on.
