Product details

Overview

Z0107NN 5AA4 from STMicroelectronics is a 5 mA sensitivity, 800 V repetitive peak off-state voltage, 1 A RMS on-state triac in SOT-223 package, designed for AC phase-control switching in microcontroller-driven home appliance loads including electrovalves, pumps, and lamp dimmers.

For engineers reviewing the Z0107NN 5AA4 datasheet, Z0107NN 5AA4 pinout, Z0107NN 5AA4 application, or Z0107NN 5AA4 equivalent, key selection criteria include gate trigger current (5 mA max), dV/dt immunity (50 V/µs min), junction-to-tab thermal resistance (25 °C/W), holding current (10 mA max), and SOT-223 mounting compatibility with PCB thermal pads.

Technical Context

This triac operates in all four quadrants with symmetrical triggering characteristics, supporting universal AC line control without polarity constraints. Its 50 V/µs minimum dV/dt immunity at 110 °C and 0.95 V threshold on-state voltage at 125 °C enable reliable commutation in noisy, thermally demanding environments.

The device uses a planar passivated silicon structure with optimized gate geometry to achieve low IGT while maintaining high surge robustness (8.5 A non-repetitive peak at 60 Hz). Thermal performance is defined by junction-to-tab resistance (25 °C/W) and rated for continuous operation up to 125 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
IT(RMS)	1 A - Continuous AC load current handling capability under full-sine wave conduction at T_tab = 90 °C
VDRM/VRRM	800 V - Maximum repetitive blocking voltage across MT1–MT2 terminals in both directions
IGT (Q1)	5 mA max - Gate current required to trigger conduction in Quadrant I, enabling direct MCU GPIO drive
dV/dt (min)	50 V/µs - Minimum rate of voltage rise the device withstands without false turn-on when gate is open
R_th(j-t)	25 °C/W - Junction-to-tab thermal resistance, defining heat transfer efficiency to PCB copper pad
V_T0	0.95 V max - Threshold on-state voltage at 125 °C, directly impacting conduction loss and self-heating
I_H	10 mA max - Holding current below which conduction ceases after gate signal removal

Pinout & Package

SOT-223 package with exposed tab (pin 4) serving as MT2 terminal and primary thermal path; molded epoxy meets UL94 V0; lead-free and halogen-free construction.

Pin/Terminal	Circuit Role	Design Meaning
1 (A1 / MT1)	Main Terminal 1	Anode 1 connection; referenced point for gate trigger and load return path
2 (G)	Gate	Control input; triggers bidirectional conduction when ≥5 mA applied relative to MT1
3 (A2 / MT2)	Main Terminal 2	Anode 2 connection; carries full load current and serves as thermal interface via exposed tab
4 (Tab)	MT2 / Thermal Pad	Electrically and thermally connected to pin 3; must be soldered to ≥5 cm² copper area for rated 1 A operation

Key Features

Feature	Design Value
Quadrant I–IV triggering	Enables single-device AC phase control without external polarity management circuitry
5 mA gate sensitivity	Allows direct drive from 3.3 V or 5 V MCU GPIO pins without buffer transistors
800 V blocking rating	Supports global mains operation (230 VAC + margin) with safety headroom against transients
25 °C/W R_th(j-t)	Permits 1 A RMS current with ≤25 K temperature rise above tab, simplifying thermal design
0.95 V V_T0 @ 125 °C	Reduces conduction loss and self-heating at elevated ambient temperatures

Equivalent & Alternatives

The following parts are listed as comparable options for similar triac switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Z0107MN	Same 5 mA IGT and 800 V rating, but TO-92 package with higher R_th(j-l) = 60 °C/W	Lower power density; limited to ≤0.5 A RMS in free-air; requires lead-forming for through-hole mounting	Select for legacy through-hole designs where thermal budget allows lower current or forced-air cooling
Z0107MUF	Identical electrical specs, SMBflat-3L package with R_th(j-a) = 75 °C/W and smaller footprint	Higher thermal resistance than SOT-223; suited for space-constrained layouts with moderate thermal mass	Select when board area is critical and average load current remains ≤0.7 A with ≥3 cm² copper pour

Compared with Z0107MN and Z0107MUF, Z0107NN 5AA4 offers optimal balance of thermal performance (25 °C/W), surface-mount compatibility, and 1 A RMS rating-making it the preferred choice for new SMT-based appliance control boards requiring robust, relay-replacement switching.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The Z0107NN 5AA4 has an operating junction temperature range of –40 °C to +125 °C. For sustained 1 A RMS conduction in SOT-223, the tab temperature must not exceed 90 °C per Table 1, requiring adequate PCB copper area (≥5 cm²) and airflow to maintain thermal margin.

Can this triac be driven directly from a 3.3 V microcontroller GPIO?

Yes-its 5 mA maximum IGT (Quadrant I) is compatible with most 3.3 V MCUs' output drive capability. A series resistor of 330 Ω limits gate current to ~6.7 mA at 3.3 V, staying within safe operating limits while ensuring reliable turn-on across temperature and process variation.

Does the SOT-223 package require thermal vias under the tab?

Thermal vias are strongly recommended beneath the exposed tab to enhance heat transfer to internal ground planes. With 5 cm² of 2 oz copper on the top layer and ≥4 thermal vias (0.3 mm diameter, spaced ≤2 mm apart), junction-to-ambient resistance drops significantly-supporting full 1 A RMS rating in compact layouts.

How does dV/dt immunity change with junction temperature?

dV/dt immunity degrades as junction temperature rises: at 110 °C, minimum specified dV/dt is 50 V/µs (Table 2); at 25 °C, it exceeds 100 V/µs (Figure 13). Designers must ensure snubber networks or layout isolation maintain margin above the 50 V/µs limit under worst-case thermal conditions.
