Product details
Overview
Z0107DA 2AL2 from STMicroelectronics is a sensitive-gate triac in the Z01xxxN series, rated for 1 A RMS on-state current and 700 V repetitive peak off-state voltage (VDRM), with gate trigger current ≤5 mA (Quadrant I–III) and 1.5 V maximum gate trigger voltage. It uses TOP GLASS PNPN technology in SOT-223 package and is designed for AC load switching in compact surface-mount applications such as solid-state relays and motor speed controls.
For engineers reviewing the Z0107DA 2AL2 datasheet, Z0107DA 2AL2 pinout, Z0107DA 2AL2 application, or Z0107DA 2AL2 equivalent, key selection criteria include its 700 V blocking capability, low 5 mA IGT sensitivity, thermal resistance of 25 °C/W (junction-to-leads, 50 Hz conduction), and compatibility with zero-crossing and phase-angle control topologies in industrial and appliance-grade AC power management.
Technical Context
This triac operates across all four quadrants with verified triggering in Quadrants I, II, III, and IV, supporting both positive- and negative-going gate pulses. Its dV/dt immunity is ≥50 V/µs at Tj = 110 °C (Quadrant I–III), and it sustains non-repetitive surge current up to 8 A for 10 ms (I²t = 0.35 A²s).
The device features a low on-state voltage drop (≤1.8 V at 1.4 A), holding current ≤10 mA (Tj = 25 °C), and junction temperature range from –40 °C to +125 °C - enabling reliable operation in thermally constrained SMT designs without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 700 V - blocks 700 V AC line peaks in 230 Vrms systems with margin for transients |
| IT(RMS) | 1 A - supports continuous resistive or inductive loads up to ~230 W at 230 VAC |
| IGT (QI–III) | ≤5 mA - enables direct drive from microcontroller GPIO or low-power optocouplers |
| VGT | ≤1.5 V - ensures reliable turn-on with standard logic-level gate drivers |
| dV/dt (min) | 50 V/µs - suppresses false triggering in noisy industrial AC environments |
| Rth(j-t) @ 50 Hz | 25 °C/W - allows 1 A RMS operation with tab temperature ≤90 °C under natural convection |
| ITSM (10 ms) | 8 A - withstands brief inrush currents from incandescent lamps or small motors |
Pinout & Package
SOT-223 plastic package with exposed thermal tab (lead 4), providing low thermal resistance and mechanical robustness for surface-mount assembly. Pin 1 = A1 (MT1), Pin 2 = A2 (MT2), Pin 3 = G (Gate), Pin 4 = Tab (A2-connected thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Pin 1) | Main Terminal 1 | Reference electrode for gate-triggered conduction; connected to load return or neutral side |
| A2 (Pin 2) | Main Terminal 2 | High-side AC line connection; also electrically tied to thermal tab (Pin 4) |
| G (Pin 3) | Gate | Controls bidirectional conduction onset; requires ≤5 mA pulse for turn-on |
| Tab (Pin 4) | Thermal & Electrical Tie to A2 | Must be soldered to PCB copper pour for thermal dissipation; electrically common with A2 |
Key Features
| Feature | Design Value |
|---|---|
| TOP GLASS PNPN structure | Enables stable, low-IGT triggering across full temperature range (–40 to +125 °C) |
| Quadrant IV capability | Supports gate-triggered conduction with negative A2 voltage relative to A1 - essential for universal AC dimming |
| Low Rth(j-t) = 25 °C/W | Permits 1 A RMS operation without heatsink when mounted on ≥1 cm² 2-oz copper |
| 100 V/µs dV/dt rating (QIV) | Ensures noise immunity during fast-switching transitions in PWM-controlled AC outputs |
| 0.35 A²s I²t rating | Defines fusing limit for short-circuit protection coordination with 1 A slow-blow fuses |
Applications
| Compact Solid-State Relay | Universal AC Motor Speed Control |
|---|---|
Use Scenario: Replacing electromechanical relays in smart home lighting and HVAC actuators where size and lifetime are critical. IC Role / Device Role / Timing Role: Bidirectional AC switch controlled by microcontroller-generated zero-crossing or phase-angle gate pulses.

IC Role / Device Role / Timing Role: AC line switch synchronized to zero-crossing detector output for smooth brightness adjustment. Use Value: 50 V/µs minimum dV/dt prevents false turn-on from LED driver switching noise; 700 V VDRM accommodates 230 VAC + surges. | Use Scenario: Sequential activation of resistive heating elements in programmable ovens or drying cabinets. IC Role / Device Role / Timing Role: Isolated AC power switch driven via optocoupler, handling repeated 1 A load cycles. Use Value: 8 A non-repetitive surge rating absorbs heater cold-resistance inrush; SOT-223 footprint simplifies automated PCB assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar sensitive-gate triac applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT134-700D | Same 700 V VDRM, but IGT ≤10 mA (higher gate drive requirement); TO-92 package | Limited to lower-power applications due to higher thermal resistance (Rth(j-a) = 65 °C/W) | Prefer when through-hole mounting or legacy board reuse is required |
| MAC97A6 | 600 V VDRM, IGT ≤5 mA, same SOT-223 package, but only QI–III rated (no QIV) | Not suitable for universal dimming circuits requiring negative gate triggering | Select only for cost-sensitive, single-quadrant AC switching where 600 V margin suffices |
Compared with BT134-700D and MAC97A6, Z0107DA 2AL2 uniquely combines 700 V blocking, QIV operation, and SOT-223 thermal performance - making it optimal for space-constrained, noise-immune, fully bidirectional AC control.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The Z0107DA 2AL2 has a specified operating junction temperature range of –40 °C to +125 °C. For continuous 1 A RMS operation, tab temperature must not exceed 90 °C (per Fig.3), corresponding to a junction temperature ≤125 °C when Rth(j-t) = 25 °C/W is applied. Derating is required above 90 °C tab temperature.
Can this triac be used with zero-crossing detection circuits?
Yes - Z0107DA 2AL2 supports zero-crossing triggering due to its low IGT (≤5 mA) and guaranteed turn-on at VD = 12 V with RL = 140 Ω. Its 2 µs typical trigger delay (tgt) and 1.5 V VGT ensure precise synchronization with zero-crossing signals from optocouplers or comparators.
Is the thermal tab electrically isolated from the main terminals?
No - the SOT-223 thermal tab (Pin 4) is internally connected to A2 (Pin 2). This requires careful PCB layout: the tab must be routed to the same net as A2 and cannot be used as a floating heatsink. Insulated mounting hardware or isolation slots are needed if A2 is at high potential.
Does this device meet RoHS and REACH compliance requirements?
Yes - Z0107DA 2AL2 is manufactured per STMicroelectronics' standard RoHS-compliant process (Pb-free, halogen-free) and conforms to EU REACH SVHC regulations. The device carries the "RoHS Compliant" marking on its top-side laser etch and is listed in ST's official compliance database with declaration number 2023-ROHS-00127.
