Product details
Overview
Z0107DA 1AA2 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 and on-state voltage ≤1.8 V at 1.4 A; it is designed for AC load switching in compact SMT-based lighting control and appliance motor circuits.
For engineers reviewing the Z0107DA 1AA2 datasheet, Z0107DA 1AA2 pinout, Z0107DA 1AA2 application, or Z0107DA 1AA2 equivalent, key selection criteria include its 700 V blocking capability, low 5 mA IGT sensitivity, SOT-223 thermal performance (Rth(j-t) = 25 °C/W at 50 Hz), and compatibility with zero-crossing or phase-angle dimming drivers.
Technical Context
This triac uses high-performance TOP GLASS PNPN structure optimized for surface-mount reliability and thermal stability. It operates across quadrants I, II, III, and IV with symmetrical triggering behavior and supports both leading- and trailing-edge phase control.
Its dV/dt immunity is ≥50 V/µs at Tj = 110 °C with gate open, and critical rate of rise of on-state current (dI/dt) reaches 10 A/µs (repetitive, 50 Hz), enabling robust commutation in inductive loads like universal motors and solenoids.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 700 V - blocks 700 V peak AC line voltage, suitable for 230 VAC mains applications with safety margin |
| IT(RMS) | 1 A - continuous RMS load current handling at 90 °C tab temperature, sufficient for LED drivers and small relays |
| IGT (max) | 5 mA - low gate drive requirement enables direct interface with microcontroller GPIO or optocoupler outputs |
| VTM (max) | 1.8 V - low conduction loss reduces power dissipation to ≤1.8 W at 1 A, easing thermal design in SOT-223 |
| dV/dt (min) | 50 V/µs - high noise immunity prevents false triggering in EMI-prone environments like motor drives |
| Tj range | –40 to +125 °C - supports industrial ambient operation without derating below 125 °C junction limit |
| Rth(j-t) | 25 °C/W - thermal resistance from junction to leads under full-conduction AC, enabling accurate tab-temp-based derating |
Pinout & Package
SOT-223 plastic package with exposed thermal pad; three terminals: A1 (MT1), A2 (MT2), and G (Gate); lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate trigger; connected to load return or neutral side in AC switch configurations |
| A2 (MT2) | Main Terminal 2 | High-side AC line connection; carries full load current and defines polarity for quadrant-sensitive triggering |
| G | Gate | Controls conduction onset; requires ≥5 mA pulse to initiate bidirectional conduction between A1 and A2 |
Key Features
| Feature | Design Value |
|---|---|
| Sensitive gate | IGT ≤ 5 mA at 25 °C - eliminates need for external gate amplification in low-power control stages |
| High dV/dt immunity | ≥50 V/µs at 110 °C - ensures stable operation in noisy 50/60 Hz AC environments with inductive kickback |
| SOT-223 thermal performance | Rth(j-t) = 25 °C/W (50 Hz) - allows 1 A RMS operation with tab temperature ≤90 °C using minimal copper area |
| Quadrant IV support | Triggerable with negative A2 voltage relative to A1 - enables full-wave phase control without polarity reversal circuitry |
Applications
| Dimmable LED Drivers | Small Appliance Motor Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT134-700D | Same 700 V VDRM and 1 A IT(RMS), but IGT = 10 mA (higher gate drive required) | Less suitable for low-power MCU GPIO direct drive; needs buffer stage for same control architecture | Select when higher dV/dt immunity (≥100 V/µs) is prioritized over gate sensitivity |
| MAC97A6 | 600 V VDRM, 0.8 A IT(RMS), IGT = 5 mA - lower voltage/current ratings | Limited to 115 VAC systems or sub-1 A loads; not drop-in for 230 VAC 1 A designs | Choose only for cost-sensitive 115 VAC consumer products where 700 V margin is unnecessary |
Compared with BT134-700D and MAC97A6, Z0107DA 1AA2 uniquely balances 700 V blocking, 1 A RMS capacity, and 5 mA gate sensitivity in SOT-223-making it optimal for space-constrained 230 VAC smart switches requiring minimal gate drive overhead.

FAQ
What is the maximum allowable junction temperature for Z0107DA 1AA2?
The absolute maximum junction temperature is +125 °C, with storage temperature ranging from –40 to +150 °C. Operation above 125 °C risks parametric shift and premature failure; thermal design must maintain Tj ≤125 °C under worst-case load and ambient conditions using Rth(j-t) = 25 °C/W at 50 Hz conduction.
Can Z0107DA 1AA2 be used in zero-crossing switch applications?
Yes - its symmetric quadrant IV triggering and 50 V/µs dV/dt immunity make it suitable for zero-crossing solid-state relays. When paired with a zero-crossing detector IC (e.g., MOC3041), it delivers low-EMI, low-noise switching ideal for resistive and lightly inductive loads.
Is Z0107DA 1AA2 compatible with lead-free reflow soldering?
Yes - it is qualified for lead-free reflow per JEDEC J-STD-020, with maximum lead temperature of 260 °C for 10 seconds. The SOT-223 package supports standard Pb-free profiles; thermal pad soldering improves heat transfer and reliability in high-duty-cycle applications.
What is the minimum gate trigger voltage (VGT) for Z0107DA 1AA2?
VGT is specified as ≤1.5 V maximum at Tj = 25 °C, with typical values near 1.0 V. This low threshold ensures reliable triggering from 3.3 V or 5 V logic-level sources without external level-shifting, provided gate current exceeds 5 mA for ≥2 µs pulse width.
