Product details
Overview
Z0107NA 1AA2 from STMicroelectronics is a 5 mA sensitive, 800 V repetitive peak off-state voltage (VRRM), 1 A RMS on-state triac in TO-92 straight-lead package, designed for AC phase-control switching in low-power home appliance loads including electrovalves, small lamp dimmers, and fan speed controllers.
For engineers reviewing the Z0107NA 1AA2 datasheet, Z0107NA 1AA2 pinout, Z0107NA 1AA2 application, or Z0107NA 1AA2 equivalent, key selection criteria include gate trigger current (IGT = 5 mA max), holding current (IH = 10 mA max), dV/dt immunity (100 V/µs min), thermal resistance (Rth(j-l) = 60 °C/W), and TO-92 lead-form compatibility with microcontroller-driven zero-crossing or random-phase control circuits.
Technical Context
This triac operates in all four quadrants (I–IV) with symmetric triggering behavior relative to A2–A1 polarity. Its gate sensitivity is optimized for direct drive from 3.3 V/5 V GPIO pins without external amplification, supported by guaranteed IGT ≤ 5 mA at 25 °C and VGT ≤ 1.3 V.
It features robust dynamic latching and holding characteristics (IL ≤ 10 mA, IH ≤ 10 mA), critical dV/dt immunity ≥ 100 V/µs at 110 °C, and dI/dt capability ≥ 20 A/µs - enabling reliable commutation in inductive AC loads such as solenoids and universal motors without snubber networks in many designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 1 A - continuous AC load current rating at TL = 50 °C, suitable for <120 W resistive or <80 W inductive loads at 230 VAC. |
| VRRM / VDRM | 800 V - peak blocking voltage ensures margin over 230 VAC mains (325 V peak) with surge tolerance up to 8.5 A non-repetitive. |
| IGT (Q1) | ≤5 mA - enables direct drive from standard MCU I/O pins without buffer stage; verified across full temperature range. |
| dV/dt (min) | 100 V/µs - suppresses false triggering in noisy AC environments with gate open, critical for fan motor and pump control. |
| Rth(j-l) | 60 °C/W - junction-to-lead thermal resistance defines maximum power dissipation (0.4 W at TL = 50 °C) in TO-92 mounting. |
| VTM | ≤1.60 V - on-state voltage drop at 1.4 A pulse limits conduction loss to <2.2 W peak, reducing heatsink requirements. |
| IL / IH | ≤10 mA - latching and holding currents ensure stable turn-on and retention during low-current AC zero-crossings in lamp and valve control. |
Pinout & Package
Package: TO-92 with straight leads (plastic), UL94 V0 epoxy, lead-free plating, halogen-free molding resin. Dimensions per Table 6: A = 1.35 mm, B = 4.70 mm, C = 2.54 mm, D = 4.40 mm, E = 12.70 mm, F = 3.70 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Main Terminal 1 | Reference terminal for gate drive; connects to neutral or low-side AC path in standard configuration. |
| A2 | Main Terminal 2 | High-side AC load connection; carries full load current and must be routed with creepage/clearance compliance. |
| G | Gate | Control input referenced to A1; triggers conduction when IGT ≥ 5 mA applied with proper polarity (Q1–Q4). |
Key Features
| Feature | Design Value |
|---|---|
| Quadrant IV operation | Enables gate triggering with negative gate-to-A1 voltage, supporting bidirectional AC control from single-polarity drivers. |
| Low IGT variation vs. Tj | IGT increases only 2.5× from 25 °C to 125 °C (Figure 6), ensuring consistent turn-on timing across operating temperature range. |
| High dV/dt immunity | 100 V/µs minimum at 110 °C prevents spurious turn-on during voltage transients in motor and transformer primary circuits. |
| Optimized for microcontroller drive | No external gate resistor required for typical 3.3 V/20 mA GPIO; compatible with PWM-based phase-angle control firmware. |
| ECOPACK® compliant | Meets RoHS, REACH, and halogen-free requirements; qualified for industrial and consumer appliance applications. |
Applications
| Electrovalve Control | Fan Speed Regulation |
|---|---|
Use Scenario: On/off control of 24 VAC or 230 VAC solenoid valves in washing machines and dishwashers. IC Role / Device Role / Timing Role: Main AC switching element triggered at zero-crossing to minimize EMI and inrush stress. Use Value: 5 mA IGT allows direct drive from MCU GPIO; 10 mA IH ensures stable hold during valve coil decay after gate signal removal. | Use Scenario: Phase-angle dimming of universal motor fans in HVAC systems and kitchen hoods. IC Role / Device Role / Timing Role: Bidirectional AC switch modulating RMS voltage delivered to motor windings. Use Value: 100 V/µs dV/dt immunity prevents false triggering from motor back-EMF spikes; TO-92 form factor fits compact PCB layouts. |
| Lamp Dimming | Door Lock Actuation |
Use Scenario: Leading-edge dimming of incandescent and halogen lamps in smart lighting modules. IC Role / Device Role / Timing Role: Random-phase or zero-crossing controlled triac delivering variable RMS voltage to filament. Use Value: 1 A IT(RMS) supports up to 230 W resistive load; 1.6 V VTM limits self-heating during extended dimmed operation. | Use Scenario: Momentary AC power delivery to electromagnetic door locks in access control panels. IC Role / Device Role / Timing Role: High-reliability AC switch activated by microcontroller for precise lock/unlock timing. Use Value: 800 V VRRM provides margin against line surges; TO-92 straight leads simplify automated assembly and reduce mechanical stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Z0107MA 1AA2 | 600 V VRRM instead of 800 V; identical IGT (5 mA), package, and thermal specs. | Suitable for 120 VAC-only regions; insufficient margin for 230 VAC surge testing. | Select when cost-sensitive and operating exclusively on 120 VAC mains with certified surge protection. |
| BT134-600E | Same TO-92 package, 4 A IT(RMS), 600 V VRRM, IGT = 5 mA, but higher Rth(j-l) = 70 °C/W. | Higher current rating allows future-proofing; lower dV/dt (50 V/µs) requires snubber in noisy motor loads. | Choose for higher-power fan or pump control where thermal headroom is available and snubber design is acceptable. |
Compared with Z0107MA 1AA2, this part adds 200 V blocking margin for global 230 VAC deployment; versus BT134-600E, it trades current headroom for superior dV/dt immunity and lower thermal resistance in TO-92 form factor.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The Z0107NA 1AA2 has an operating junction temperature range of –40 °C to +125 °C. Continuous operation at Tj = 125 °C is permitted only when lead temperature (TL) is maintained at ≤50 °C per absolute maximum ratings, requiring appropriate PCB copper area or minimal ambient derating in sealed enclosures.
Can this triac be driven directly from a 3.3 V microcontroller GPIO?
Yes - with IGT ≤ 5 mA and VGT ≤ 1.3 V at 25 °C, the Z0107NA 1AA2 can be driven directly from a 3.3 V MCU GPIO sourcing ≥6 mA (e.g., STM32, ESP32, PIC18). No series gate resistor is needed for basic on/off; a 100 Ω resistor is recommended for phase-angle control to limit peak gate current during fast transitions.
Is a snubber circuit required for inductive loads?
A snubber is not mandatory for most fan or pump loads due to the device's 100 V/µs dV/dt immunity and 20 A/µs critical di/dt rating. However, for highly inductive loads with rapid current interruption (e.g., relay coils), a 100 Ω + 100 nF RC snubber across MT2–MT1 improves reliability and reduces EMI per Figure 8 recommendations in DS2116.
What is the difference between '1AA2' and '2AL2' packaging codes?
'1AA2' denotes TO-92 bulk packaging (2500 units per box), while '2AL2' indicates TO-92 ammopack (2000 units per tube). Both use straight leads; '1AA2' is optimized for manual or semi-automated insertion, whereas '2AL2' supports vibration-resistant transport and automated pick-and-place with tube feeders.
