Product details
Overview
AC10DSMA(2)-AZ from Renesas Electronics is a resin-molded 10 A, 400 V repetitive peak off-state voltage TRIAC designed for AC power control in solid-state switching applications. It features 80 A surge on-state current (50 Hz), 50 A/μs critical rate of rise of on-state current, and gate trigger current ≤20 mA in Modes I/III/IV - enabling reliable phase-angle control in motor speed and heater temperature regulation circuits.
For engineers reviewing the AC10DSMA(2)-AZ datasheet, AC10DSMA(2)-AZ pinout, AC10DSMA(2)-AZ application, or AC10DSMA(2)-AZ equivalent, key selection criteria include its TO-220AB-compatible package, junction-to-case thermal resistance of 3.5°C/W, minimum holding current of 30 mA, and guaranteed dv/dt immunity of 100 V/μs at 125°C - all critical for robust AC line commutation in industrial controls.
Technical Context
This TRIAC operates in four quadrant gate triggering modes (I, II, III, IV) with symmetrical gate sensitivity (≤20 mA IGT, ≤1.5 V VGT) across −40°C to +125°C ambient. Its 3.5°C/W junction-to-case thermal resistance supports continuous 10 A RMS conduction at TC = 85°C without forced cooling.
The device meets standard industrial reliability requirements with 28 A²s fusing I²t rating (1–10 ms), 500 V non-repetitive peak off-state voltage, and commutating dv/dt capability of 10 μs - ensuring stable turn-off during inductive load switching in mains-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 400 V - maximum repetitive AC blocking voltage; defines safe operating range for 230 VAC mains applications with margin. |
| IT(RMS) | 10 A at TC = 85°C - continuous AC load current capacity with standard heatsinking. |
| ITSM | 80 A (50 Hz, 1 cycle) - surge withstand for motor startup or lamp inrush without failure. |
| dIT/dt | 50 A/μs - minimum required rate of current rise to ensure reliable turn-on without false triggering. |
| Rth(j-c) | 3.5°C/W - thermal resistance from junction to case; determines heatsink size needed for thermal stability. |
| VGD | 0.3 V min at 125°C - gate non-trigger voltage threshold; ensures noise immunity against spurious gate activation. |
| (dv/dt)c | 10 V/μs - commutating dv/dt rating; guarantees safe commutation with inductive loads like motors. |
Pinout & Package
AC10DSMA(2)-AZ uses a TO-220AB-compatible resin-molded package with 3 terminals and standard 2.54 mm lead pitch. Case temperature measurement point is defined per Figure 13 in D13661EJ5V0DS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Main Terminal 1 | Anode-side main current path; connected to load return or neutral in AC phase-control topologies. |
| T2 | Main Terminal 2 | Cathode-side main current path; typically connected to AC line input or hot side. |
| Gate | Control Input | Triggers conduction between T1 and T2 in any quadrant; requires ≤20 mA pulse for reliable turn-on. |
Key Features
| Feature | Design Value |
|---|---|
| Four-quadrant gate triggering | Enables universal phase-control operation with AC waveforms regardless of polarity - no external polarity reversal needed. |
| TO-220AB mechanical compatibility | Direct drop-in replacement for legacy TO-220AB TRIACs without PCB layout changes or mounting hardware redesign. |
| High dIT/dt immunity (50 A/μs) | Prevents false triggering under fast-rising current transients common in transformer-coupled or inductive drive circuits. |
| Guaranteed 100 V/μs dv/dt at 125°C | Ensures stable blocking during high-frequency noise or rapid voltage transients on AC mains lines. |
| 28 A²s fusing I²t rating | Provides predictable failure mode under short-circuit conditions - supports coordination with upstream fuses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TRIAC switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT139-600 | 600 V VDRM, 16 A IT(RMS), higher thermal resistance (4.0°C/W) | Higher voltage margin but lower current density; requires larger heatsink for same 10 A duty | Select when 600 V blocking is mandatory and board space allows larger thermal solution. |
| MAC10DZ | 400 V VDRM, 10 A IT(RMS), TO-220 package, lower ITSM (70 A) | Near-identical electrical specs but reduced surge rating; less robust for motor startup surges | Acceptable where surge stress is low and cost optimization is prioritized over margin. |
Compared with BT139-600 and MAC10DZ, AC10DSMA(2)-AZ delivers optimal balance of 400 V blocking, 10 A RMS rating, and 80 A surge capability in a thermally efficient TO-220AB-compatible package - making it preferred for space-constrained industrial AC control designs requiring proven reliability.

FAQ
What is the maximum junction temperature specification for AC10DSMA(2)-AZ?
The AC10DSMA(2)-AZ has a specified junction temperature range of −40°C to +125°C. This rating enables operation in harsh industrial environments where ambient temperatures exceed 85°C, provided thermal design maintains Tj within limits using the documented 3.5°C/W junction-to-case thermal resistance. The AC10DSMA(2)-AZ must not be operated beyond this absolute maximum to prevent irreversible degradation.
Does AC10DSMA(2)-AZ support all four gate triggering quadrants?
Yes, AC10DSMA(2)-AZ supports full four-quadrant triggering (Modes I, II, III, IV) with verified gate trigger current ≤20 mA and gate trigger voltage ≤1.5 V in Modes I, III, and IV. Mode II data is not specified in the datasheet D13661EJ5V0DS, so designers should avoid relying on Mode II operation unless independently validated. The AC10DSMA(2)-AZ is optimized for robust triggering in the three fully characterized modes.
What is the gate non-trigger voltage (VGD) of AC10DSMA(2)-AZ and why does it matter?
The AC10DSMA(2)-AZ specifies a minimum gate non-trigger voltage (VGD) of 0.3 V at Tj = 125°C and VDM = 2/3 VDRM. This parameter defines the maximum noise voltage the gate can tolerate before unintended turn-on occurs. A higher VGD improves immunity to electromagnetic interference in noisy industrial settings - a key reliability factor for the AC10DSMA(2)-AZ in PLC output modules or motor drives.
Can AC10DSMA(2)-AZ replace older NEC TRIACs without layout changes?
Yes, AC10DSMA(2)-AZ is explicitly designed as a direct mechanical and electrical replacement for legacy NEC TRIACs in TO-220AB packages. Its pinout (T1, T2, Gate), lead pitch (2.54 mm), and outline dimensions match TO-220AB standards. No PCB modifications are required when upgrading from compatible predecessors, preserving existing thermal and mechanical design integrity for the AC10DSMA(2)-AZ.
What is the fusing I²t rating of AC10DSMA(2)-AZ and how is it used in circuit protection?
The AC10DSMA(2)-AZ has a fusing I²t rating of 28 A²s for time intervals between 1 ms and 10 ms. This value defines the energy threshold beyond which the device will fail open-circuit under short-circuit conditions. Engineers use this rating to coordinate upstream fuse selection - ensuring the fuse clears before the AC10DSMA(2)-AZ fuses, thereby protecting downstream circuitry while maintaining system-level fault tolerance.
