Product details
Overview
Z0110MA from STMicroelectronics is a 1 A, 600 V RMS-rated sensitive-gate triac in TO-92 package, designed for AC phase-control switching in low-power home appliance loads. It delivers 25 mA maximum gate trigger current (IGT), 1.6 V max on-state voltage (VT) at 25 °C, and supports dV/dt immunity up to 100 V/µs - enabling direct microcontroller drive in electrovalve, pump, and small lamp control circuits.
For engineers reviewing the Z0110MA datasheet, Z0110MA pinout, Z0110MA application, or Z0110MA equivalent, key selection criteria include gate sensitivity (25 mA IGT), thermal resistance (Rth(j-l) = 60 °C/W), junction temperature range (–40 to +125 °C), and TO-92 lead-form compatibility with legacy PCB layouts and low-cost assembly processes.
Technical Context
This triac operates in all four quadrants with symmetrical triggering behavior, supporting bidirectional AC conduction without external polarity management. Its gate structure is optimized for low IGT (25 mA max) while maintaining robust dI/dt capability (20 A/µs) and holding current (IH ≤ 25 mA) across –40 to +125 °C junction temperature.
Static characteristics include VT ≤ 1.60 V at ITM = 1.4 A and dynamic resistance Rd ≤ 400 mΩ at 125 °C, ensuring low conduction loss in thermally constrained TO-92 applications. The device meets IEC 61000-4-5 surge immunity requirements via its 8.5 A non-repetitive surge rating (60 Hz, 16.7 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 1 A - continuous AC load current handling in TO-92 package at TL = 50 °C |
| VDRM / VRRM | 600 V - peak repetitive off-state voltage rating, suitable for 230 VAC mains with safety margin |
| IGT (Q1) | 25 mA max - gate trigger current enabling direct drive from 3.3 V / 5 V MCU GPIO pins |
| dV/dt (min) | 100 V/µs - immunity to false triggering from fast transient noise on AC line |
| Rth(j-l) | 60 °C/W - junction-to-lead thermal resistance defining maximum power dissipation in free-air TO-92 mounting |
| VT (max) | 1.60 V at 25 °C - on-state voltage drop determining conduction loss and self-heating at full load |
| IH (max) | 25 mA - minimum holding current required to sustain conduction after gate turn-off |
Pinout & Package
Package: TO-92 (straight leads), plastic, lead-free, halogen-free, UL94 V0 compliant. Thermal resistance Rth(j-l) = 60 °C/W; weight = 0.2 g; base quantity = 2500 pcs/bulk (1AA2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Main Terminal 1 | Reference terminal for gate drive; connected to neutral or low-side AC return path |
| A2 | Main Terminal 2 | High-side AC load connection; carries full RMS current and must be routed with creepage/clearance compliance |
| G | Gate | Sensitive control input; requires ≤25 mA pulse to trigger conduction in any quadrant |
Key Features
| Feature | Design Value |
|---|---|
| Quadrant IV operation | Enables reliable triggering with negative gate-to-A1 voltage, critical for zero-crossing dimmer IC interfaces |
| Low IGT variation over temperature | IGT increases only ~2.5× from 25 °C to 125 °C (per Fig. 6), simplifying gate driver design |
| High dV/dt immunity | 100 V/µs minimum at 110 °C ensures noise immunity in EMI-prone appliance motor-drive environments |
| TO-92 thermal performance | Rth(j-l) = 60 °C/W allows 0.4 W dissipation at 50 °C lead temperature - sufficient for 1 A resistive loads |
Applications
| Electrovalve Control | Pump Motor Switching |
|---|---|
Use Scenario: On/off control of 230 VAC solenoid valves in washing machines and dishwashers. IC Role / Device Role / Timing Role: Main AC power switch triggered by MCU PWM output through optocoupler or level-shifter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT134-600E | Same TO-92 package, 4 A IT(RMS), 600 V VDRM, but 50 mA IGT (less sensitive) | Requires external gate driver for MCU-level logic; higher surge rating suits heavier loads | Select when higher current headroom or legacy design reuse is needed, not for direct GPIO drive |
| Z0107MA | Same TO-92 package, 600 V, but 5 mA IGT (higher sensitivity), lower dV/dt (50 V/µs) | Better for ultra-low-power MCU systems; reduced noise immunity limits use in motor-noise environments | Select when gate drive voltage/current budget is extremely tight and EMI is well-controlled |
Compared with BT134-600E and Z0107MA, Z0110MA balances gate sensitivity (25 mA), noise immunity (100 V/µs), and thermal capability (60 °C/W) for cost-sensitive, space-constrained home appliance AC switching where direct microcontroller interface is required.

FAQ
What is the maximum allowable junction temperature for Z0110MA?
The absolute maximum operating junction temperature is +125 °C, with storage temperature extending to +150 °C. Derating begins above 50 °C lead temperature per Figure 2; sustained operation at full 1 A RMS requires heatsinking or airflow if ambient exceeds 40 °C.
Can Z0110MA be driven directly from a 3.3 V microcontroller GPIO?
Yes - with appropriate current-limiting resistor. At 25 °C, IGT is guaranteed ≤25 mA; using a 100 Ω resistor with 3.3 V yields 33 mA peak gate current, safely exceeding trigger requirement while limiting IGM to <1 A per pulse (within PG(AV) = 1 W limit).
Does Z0110MA require a snubber circuit in resistive load applications?
No snubber is required for pure resistive loads like lamps or heaters. However, inductive loads (e.g., pumps, solenoids), a RC snubber (e.g., 100 Ω + 100 nF) is recommended to suppress dV/dt spikes exceeding 100 V/µs and prevent false triggering.
How does Z0110MA differ from Z0110NA?
Z0110NA shares identical electrical specs and TO-92 package but has 800 V VDRM/VRRM instead of 600 V. This provides higher mains voltage margin for 277 VAC or unstable grid applications, with no change to gate drive, thermal, or pinout characteristics.
