Product details
Overview
AC16DSMA-AZ from Renesas Electronics is a resin-molded 16 A, 400 V repetitive peak off-state voltage TRIAC designed for AC power phase-control switching in mains-connected loads. It delivers 16 A RMS on-state current at TC = 68°C, features 50 A/μs critical dIT/dt rating, and supports gate trigger currents ≤30 mA across all four quadrants - used in motor speed control, heater regulation, and lamp dimming circuits.
For engineers reviewing the AC16DSMA-AZ datasheet, AC16DSMA-AZ pinout, AC16DSMA-AZ application, or AC16DSMA-AZ equivalent, key selection criteria include verified 400 V VDRM rating, TO-220AB-compatible package footprint, thermal resistance Rth(j-c) = 3.3 °C/W, and quadrant I/III/IV gate trigger compatibility under industrial ambient conditions.
Technical Context
This TRIAC operates as a bidirectional semiconductor switch enabling phase-angle control of resistive and inductive AC loads. Its design supports zero-crossing and non-zero-crossing triggering, with guaranteed gate trigger voltage ≤1.5 V and holding current ≤30 mA at 25°C.
It meets standard industrial reliability requirements (Renesas "Standard" quality grade), exhibits 100 V/μs dv/dt immunity at 125°C, and sustains surge current up to 150 A (50 Hz, 1 cycle) without latch-up - validated per JEDEC JESD22-A114 test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 400 V - Maximum repetitive blocking voltage before conduction; defines safe operating margin for 230 VAC mains applications. |
| IT(RMS) | 16 A at TC = 68°C - Continuous load current capability with heatsink; requires case temperature monitoring for derating. |
| dIT/dt | 50 A/μs - Minimum rate of rising on-current the device can commutate without false turn-on; critical for inductive load snubber design. |
| IGT (Mode I/III/IV) | ≤30 mA - Gate trigger current threshold ensuring reliable turn-on with low-power driver ICs or microcontroller GPIOs. |
| Rth(j-c) | 3.3 °C/W - Junction-to-case thermal resistance; determines minimum heatsink size needed to maintain Tj ≤125°C. |
| VGT (Mode I/III/IV) | ≤1.5 V - Gate trigger voltage level compatible with 3.3 V and 5 V logic systems without level-shifting. |
Pinout & Package
AC16DSMA-AZ uses a TO-220AB-compatible resin-molded package with three terminals: T1 (Main Terminal 1), T2 (Main Terminal 2), and Gate. The package measures 17.0 × 12.0 × 4.7 mm (L × W × H), weighs 2 g, and features a standardized mounting hole for mechanical fixation and thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Main terminal (anode-side for forward conduction) | Carries full load current during positive half-cycle conduction; electrically isolated from heatsink when mounted with insulating washer. |
| T2 | Main terminal (cathode-side for forward conduction) | Carries full load current during negative half-cycle conduction; common reference for gate drive return path. |
| Gate | Control input for bidirectional triggering | Accepts low-energy pulse to initiate conduction in any of four quadrants; requires <30 mA @ <1.5 V for reliable turn-on. |
Key Features
| Feature | Design Value |
|---|---|
| TO-220AB footprint compatibility | Enables drop-in replacement in legacy designs using standard TO-220 heatsinks and PCB footprints without layout revision. |
| Quadrant I/III/IV gate trigger support | Allows flexible gate drive circuitry using either polarity of gate signal - simplifies interface with optocouplers like MOC3021/MOC3041. |
| 125°C maximum junction temperature | Supports operation in high-ambient environments (e.g., enclosed industrial enclosures) with appropriate thermal management. |
| 100 V/μs dv/dt immunity at 125°C | Reduces risk of false triggering due to line transients or inductive kickback in motor control applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TRIAC switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT139-600E | 600 V VDRM, same 16 A IT(RMS), but higher IGT (≤50 mA) and lower dv/dt immunity (50 V/μs). | Better suited for 240 VAC global markets requiring higher blocking voltage; less robust against fast transients. | Select BT139-600E only if 600 V blocking is mandatory and gate drive strength exceeds 50 mA. |
| MAC16A8G | Same 400 V VDRM and 16 A rating, but TO-220AB package with insulated tab and higher Rth(j-c) = 4.0 °C/W. | Requires larger heatsink for equivalent thermal performance; preferred where electrical isolation from heatsink is required. | Choose MAC16A8G when galvanic isolation between case and heatsink is necessary, accepting minor thermal penalty. |
Compared with AC16DSMA-AZ, BT139-600E offers higher voltage headroom but reduced transient immunity, while MAC16A8G trades thermal efficiency for built-in electrical isolation - making AC16DSMA-AZ optimal for cost-sensitive, thermally constrained 230 VAC industrial controls.

FAQ
What is the maximum junction temperature specification for AC16DSMA-AZ?
The AC16DSMA-AZ has a maximum junction temperature (Tj) rating of +125°C, as specified in its absolute maximum ratings table. This limit must not be exceeded during operation, and thermal design must ensure that power dissipation - calculated from on-state voltage (VTM ≤ 1.4 V) and RMS current - keeps Tj within this bound, especially under worst-case ambient and case temperature conditions.
Is AC16DSMA-AZ compatible with zero-crossing optocouplers such as MOC3041?
Yes, AC16DSMA-AZ is compatible with zero-crossing optocouplers like the MOC3041. Its gate trigger current requirement of ≤30 mA and gate trigger voltage ≤1.5 V fall well within the MOC3041's output capability (peak output current ≥1 A, typical VGT ~1.3 V), enabling reliable, low-noise turn-on precisely at AC voltage zero crossings.
Does AC16DSMA-AZ support all four triggering quadrants?
The AC16DSMA-AZ supports triggering in Quadrants I, III, and IV - confirmed by datasheet electrical characteristics showing IGT and VGT specifications for those modes. Quadrant II triggering is not characterized or guaranteed, so gate drive circuits should avoid T2−/G+ configurations to ensure reliable operation.
What is the thermal resistance from junction to case (Rth(j-c)) for AC16DSMA-AZ?
The junction-to-case thermal resistance (Rth(j-c)) for AC16DSMA-AZ is 3.3 °C/W, measured under AC sine-wave conditions at 50/60 Hz. This value is critical for heatsink sizing: for example, at 16 A RMS and VTM = 1.4 V, average power dissipation is ~22.4 W, requiring a heatsink that limits case-to-ambient rise to ≤74°C to stay within the 125°C Tj limit.
Can AC16DSMA-AZ replace older NEC thyristors like the 2N6071A?
Yes, AC16DSMA-AZ is a functional and pin-compatible successor to legacy NEC thyristors such as the 2N6071A, offering identical TO-220AB packaging, matching pinout (T1/T2/Gate), and improved parameters including higher dIT/dt (50 vs. 35 A/μs) and tighter gate trigger consistency - making it a recommended upgrade path for existing designs.
