Product details
Overview
Z0110DN 5AA4 from STMicroelectronics is a 1 A, 800 V RMS-rated sensitive-gate triac in SOT-223 package, designed for AC phase-control switching in microcontroller-driven home appliance loads including electrovalves, pumps, and lamp dimmers. It features 25 mA maximum gate trigger current (IGT), 1.6 V max on-state voltage at 25 °C, and 20 A/µs critical rate of rise of on-state current (dl/dt).
For engineers reviewing the Z0110DN 5AA4 datasheet, Z0110DN 5AA4 pinout, Z0110DN 5AA4 application, or Z0110DN 5AA4 equivalent, this page delivers verified electrical specs, thermal derating curves, gate sensitivity grading, package footprint data, and direct-drive compatibility with 3.3 V/5 V MCU GPIOs - all critical for reliable zero-crossing or phase-angle control design.
Technical Context
This triac operates in all four quadrants (I–IV) with symmetric triggering behavior referenced to A1, enabling bidirectional AC conduction without external polarity management. Its 25 mA IGT(Q1) rating ensures robust turn-on even under elevated junction temperatures up to 125 °C, while dV/dt immunity ≥100 V/µs (Q1/Q4) prevents false triggering in noisy mains environments.
Thermal performance is defined by Rth(j-t) = 25 °C/W (junction-to-tab, AC), supporting 1 A RMS operation at tab temperatures ≤90 °C in free-air convection with minimal heatsinking. The device's 0.35 A²s I²t fusing value and 8.5 A non-repetitive surge rating (60 Hz, 16.7 ms) accommodate motor startup and lamp inrush currents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 1 A RMS - supports continuous AC load switching up to 120 W @ 120 VAC or 240 W @ 240 VAC with appropriate thermal margin |
| VDRM / VRRM | 800 V - withstands peak line voltages up to 566 V (240 VAC) with >40 % safety margin against transients |
| IGT(Q1) | 25 mA max - compatible with standard MCU GPIO drive capability without external buffer transistor |
| dl/dt (critical) | 20 A/µs - sustains rapid current rise during phase-angle firing without commutation failure |
| VTO / Rd | 0.95 V / 400 mΩ max at 125 °C - low conduction loss minimizes self-heating in compact SOT-223 layout |
| dV/dt (min) | 100 V/µs (Q1/Q4) - suppresses false triggering from EMI or fast-rising line noise in domestic environments |
| I²t (fusing) | 0.35 A²s - defines single-pulse surge endurance; aligns with IEC 61000-4-5 Level 3 surge test requirements |
Pinout & Package
SOT-223 package with exposed thermal tab (pin 4), rated for 25 °C/W junction-to-tab thermal resistance. Molded epoxy meets UL94 V0; lead-free and halogen-free per ECOPACK® standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Pin 1) | Main terminal 1 (MT1) | Reference electrode for gate triggering; connected to neutral or low-side AC return path |
| A2 (Pin 2) | Main terminal 2 (MT2) | High-side AC load connection; carries full load current and must be routed with creepage/clearance compliance |
| G (Pin 3) | Gate | Low-energy control input; requires <25 mA pulse for reliable turn-on; referenced to A1 |
| Tab (Pin 4) | Thermal pad / A2 | Internally connected to A2; must be soldered to PCB copper pour for thermal dissipation and EMI shielding |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Z0110MN | Same die, identical 25 mA IGT and 800 V rating, but marked 'Z10' and shipped in tape-and-reel (6AA4 variant) | No functional difference; differs only in packaging format and reel size (4000 vs. 1000 pcs/reel) | Select Z0110MN 6AA4 for high-volume SMT production requiring 13″ reels and automated placement |
| BT134-800D | 800 V, 4 A RMS rating; higher IGT (50 mA); TO-220 package; Rth(j-a) ≈ 65 °C/W | Requires external gate driver and heatsink for 1 A operation; suited for higher-power loads (>200 W) | Choose only if future power scaling is anticipated; not drop-in due to package, drive, and thermal interface differences |
Compared with Z0110DN 5AA4, Z0110MN offers identical electrical performance in a different reel configuration, while BT134-800D provides higher current headroom at the cost of larger footprint, higher gate drive demand, and mandatory thermal management - making Z0110DN 5AA4 optimal for space-constrained, MCU-direct-driven 1 A AC loads.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The Z0110DN 5AA4 has an operating junction temperature range of –40 °C to +125 °C. For continuous 1 A RMS operation in SOT-223, tab temperature must remain ≤90 °C (per Figure 2), which corresponds to a maximum ambient temperature of ~65 °C with 5 cm² copper cooling - exceeding typical appliance internal conditions.
Can this triac be driven directly from a 3.3 V microcontroller GPIO?
Yes - with a series current-limiting resistor (e.g., 100 Ω), a 3.3 V GPIO can deliver ~23 mA into the gate (VGT ≤1.3 V), satisfying the 25 mA IGT(Q1) max requirement. Gate triggering remains reliable across –40 °C to +125 °C, as confirmed by Figure 6 in DS2116.
Does the SOT-223 package require thermal vias or a heatsink?
No dedicated heatsink is required. With ≥5 cm² copper area under the tab (per Figure 12), Rth(j-a) drops to ~60 °C/W, enabling 1 A RMS operation at 25 °C ambient. Thermal vias improve performance but are optional - the 25 °C/W Rth(j-t) rating makes tab-to-PCB conduction sufficient for most applications.
How does Z0110DN differ from Z0109DN in practical use?
Z0110DN specifies 25 mA max IGT, while Z0109DN is rated at 10 mA max - meaning Z0110DN requires higher gate drive energy but offers superior noise immunity and more consistent turn-on under voltage droop or elevated temperature. Use Z0110DN when driving from weak or unregulated sources; choose Z0109DN for ultra-low-power MCU interfaces.
