Product details

Overview

AC10DSMA(1)-AZ from Renesas Electronics is a resin-molded 10 A, 400 V repetitive peak off-state voltage TRIAC designed for AC power phase-control switching in mains-connected loads. It delivers 80 A surge current (50 Hz), supports gate trigger currents ≤20 mA across Modes I/III/IV, and operates with junction temperatures from −40°C to +125°C. It is used in motor speed control circuits where zero-crossing–independent triggering and robust dv/dt immunity are required.

For engineers reviewing the AC10DSMA(1)-AZ datasheet, AC10DSMA(1)-AZ pinout, AC10DSMA(1)-AZ application, or AC10DSMA(1)-AZ equivalent, this page provides verified electrical ratings, thermal resistance (R_th(j-c) = 3.5°C/W), gate trigger behavior across temperature, and validated alternatives for solid-state AC switching designs.

Technical Context

The AC10DSMA(1)-AZ implements a four-quadrant TRIAC structure enabling gate-triggered conduction regardless of T1/T2 polarity combinations-critical for universal AC phase control. Its dI_T/dt rating of 50 A/μs and commutating dv/dt rating of 10 V/μs ensure reliable turn-on and commutation under inductive load conditions without false triggering.

Thermal performance is defined by junction-to-case resistance of 3.5°C/W, validated at TC = 85°C with IT(RMS) = 10 A, and supported by transient thermal impedance curves up to 100 cycles. Gate drive requirements are specified for f ≥ 50 Hz, duty ≤ 10%, with PGM = 5.0 W and PG(AV) = 0.5 W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	400 V - Maximum repetitive blocking voltage in off-state; defines safe operating range for 230 V AC mains with margin.
I_T(RMS)	10 A at T_C = 85°C - Continuous RMS current handling capacity with heatsink; derates linearly above 85°C case temp.
I_TSM	80 A (50 Hz, 1 cycle) - Surge withstand capability for motor startup or lamp inrush without latch-up or failure.
dI_T/dt	50 A/μs - Minimum rate of rising on-state current before commutation failure; ensures robust turn-on with inductive loads.
R_th(j-c)	3.5°C/W - Junction-to-case thermal resistance; enables thermal design using standard TO-220AB-compatible mounting.
V_GT	≤1.5 V (Modes I/III/IV, T_j = 25°C) - Maximum gate trigger voltage; determines minimum driver output compliance for reliable firing.
I_GT	≤20 mA (Modes I/III/IV, T_j = 25°C) - Maximum gate trigger current; sets driver current sourcing requirement for microcontroller GPIO or optocoupler outputs.

Pinout & Package

AC10DSMA(1)-AZ uses a resin-molded TO-220AB–compatible package (17 mm × 12 mm × 4.7 mm max height) with three terminals: T1 (Main Terminal 1), T2 (Main Terminal 2), and Gate. Mounting requires insulated screw or clip to heatsink due to electrically active tab (T2).

Pin/Terminal	Circuit Role	Design Meaning
1 (T1)	Main terminal anode (MT1)	Current return path during conduction; referenced as cathode in quadrant I/II operation; electrically isolated from case.
2 (T2)	Main terminal cathode (MT2)	Electrically connected to metal tab/case; serves as common reference and heatsink interface; must be insulated if mounted to grounded chassis.
3 (Gate)	Control input	Triggers conduction between T1 and T2; polarity-sensitive relative to T2; requires ≤20 mA pulse with ≤1.5 V compliance.

Key Features

Feature	Design Value
Four-quadrant triggering	Supports gate firing in all voltage/current polarity combinations (Modes I–IV); eliminates need for external polarity management circuitry.
High dv/dt immunity	100 V/μs (T_j = 125°C) - Resists false turn-on from fast-rising line transients in noisy industrial environments.
TO-220AB drop-in compatibility	Identical footprint and mounting hole pattern to industry-standard TO-220AB; enables direct replacement without PCB redesign.
Robust surge rating	80 A single-cycle surge (50 Hz) - Withstands high inrush currents from universal motors or cold filament lamps without degradation.
Wide temperature operation	−40°C to +125°C junction range - Validated for use in unventilated enclosures or outdoor-rated equipment with ambient extremes.

FAQ

What is the maximum repetitive peak off-state voltage (V_DRM) for AC10DSMA(1)-AZ?

The AC10DSMA(1)-AZ has a repetitive peak off-state voltage (V_DRM) of 400 V, as confirmed in the official Renesas datasheet D13661EJ5V0DS. This rating ensures safe blocking of 230 V AC mains with sufficient margin against transients. The non-repetitive peak off-state voltage (V_DSM) is 500 V, supporting short-duration overvoltage events without breakdown.

Does AC10DSMA(1)-AZ support four-quadrant triggering?

Yes, AC10DSMA(1)-AZ supports full four-quadrant triggering (Modes I–IV), as explicitly documented in its electrical characteristics table. Gate trigger current (I_GT) and voltage (V_GT) are specified for Modes I, III, and IV, and the device structure enables conduction initiation regardless of T1/T2 polarity - a key requirement for universal AC phase-control applications.

What is the thermal resistance (R_th(j-c)) of AC10DSMA(1)-AZ, and how is it measured?

The junction-to-case thermal resistance R_th(j-c) of AC10DSMA(1)-AZ is 3.5°C/W, measured under sinusoidal 50/60 Hz current conditions with T_C = 85°C and I_T(RMS) = 10 A, per Figure 13 and thermal resistance note in the Renesas datasheet. This value applies to standard TO-220AB-compatible mounting with thermal compound and adequate heatsinking.

Can AC10DSMA(1)-AZ replace TO-220AB packaged TRIACs without PCB changes?

Yes, AC10DSMA(1)-AZ is explicitly designed as a TO-220AB package replacement, with identical mechanical dimensions, mounting hole positions, and terminal layout (T1–T2–Gate). The datasheet confirms "Can be replaced with TO-220AB package", and the package drawing shows 2.54 mm lead pitch and 17 mm × 12 mm outline matching JEDEC TO-220AB standards.

What is the gate trigger current (I_GT) specification for AC10DSMA(1)-AZ at elevated temperature?

At T_j = 125°C, the gate trigger current I_GT for AC10DSMA(1)-AZ increases to ≤50 mA for Modes I/III/IV, as shown in Figure 5 of the Renesas datasheet. At 25°C, it is ≤20 mA. Designers must ensure gate drivers maintain sufficient current sourcing capability across the full −40°C to +125°C junction range to guarantee reliable turn-on.
