Product details

Overview

Z0107MN6AA4 from STMicroelectronics is a 5 mA sensitive, 800 V repetitive peak off-state voltage (VRRM), 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 fan speed controllers.

For engineers reviewing the Z0107MN6AA4 datasheet, Z0107MN6AA4 pinout, Z0107MN6AA4 application, or Z0107MN6AA4 equivalent, this part supports direct MCU gate drive with low IGT, delivers stable latching/holding behavior up to 125 °C junction temperature, and maintains dV/dt immunity ≥50 V/µs at elevated temperatures.

Technical Context

This triac operates in all four quadrants with verified triggering sensitivity of 5 mA max (Q1–Q3) and 7 mA max (Q4), enabling reliable turn-on under asymmetric AC conditions. Its dynamic resistance (R_d) is ≤400 mΩ at 125 °C, supporting low conduction loss in thermally constrained environments.

The device features a minimum critical dV/dt of 50 V/µs (T_j = 110 °C, gate open) and a minimum commutating dV/dt (dV/dt)_c of 2 V/µs - critical for snubberless operation in resistive and inductive loads like motor windings and solenoids.

Key Specifications

Parameter	Value and Actual Design Meaning
IT(RMS)	1 A - continuous AC load current capability with SOT-223 tab heatsinking at T_tab ≤ 107 °C
VDRM / VRRM	800 V - peak blocking voltage across MT1–MT2, suitable for 230 VAC mains with safety margin
IGT (Q1–Q3)	5 mA max - gate current required for reliable turn-on using standard GPIO without external amplification
VGT	1.3 V max - compatible with 3.3 V and 5 V logic-level microcontrollers
dV/dt (min)	50 V/µs - enables snubberless operation in fan and pump motor control circuits
IL / IH	15 mA / 10 mA max - ensures stable latching and holding during zero-crossing dimming or soft-start sequences
R_th(j-t)	25 °C/W - thermal resistance from junction to SOT-223 tab, enabling 0.7 W dissipation at ΔT = 17.5 °C

Pinout & Package

SOT-223 package: surface-mount, 4-pin (3 active + tab), thermally enhanced with exposed metal tab (A2) for PCB heatsinking. Tab electrically connected to MT2 (A2).

Pin/Terminal	Circuit Role	Design Meaning

A2 (MT2)	Main Terminal 2	AC line input or high-side connection; tab is electrically tied to A2 for thermal conduction
G	Gate	Trigger control input; requires ≥5 mA pulse for Q1/Q3 turn-on; polarity-insensitive for full-wave AC
Tab (exposed)	MT2 (A2)	Thermal and electrical connection to MT2; must be soldered to copper pour ≥5 cm² for rated IT(RMS)

Key Features

Feature	Design Value

Alternative Part	Technical Difference	Application Difference	Selection Advice
BT134-800D	TO-220 package, 4 A IT(RMS), 800 V VRRM, IGT = 5 mA - higher current rating but larger footprint	Used in higher-power fan/pump systems requiring >1 A load current or forced-air cooling	Select when thermal budget exceeds SOT-223 capability or mechanical mounting requires TO-220 screw terminals
Z0107NA	TO-92 package, identical electrical specs (5 mA IGT, 800 V VRRM, 1 A IT(RMS)), same die	Preferred where through-hole assembly, manual repair, or lead-forming flexibility is required	Select for legacy production lines, prototyping, or applications needing hand-solderable leads

Compared with BT134-800D and Z0107NA, Z0107MN6AA4 offers optimal balance of surface-mount miniaturization, thermal performance via tab heatsinking, and compatibility with modern automated assembly - making it ideal for space-constrained, high-volume home appliance PCBs.

FAQ

What is the maximum junction temperature for continuous operation?

The Z0107MN6AA4 has an operating junction temperature range of –40 °C to +125 °C. Continuous operation at 125 °C requires maintaining tab temperature ≤107 °C per SOT-223 derating curves, achievable with ≥5 cm² copper area and adequate airflow or conduction paths.

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

Yes - with V_GT ≤ 1.3 V and I_GT ≤ 5 mA (Q1–Q3), the Z0107MN6AA4 can be triggered reliably using a 3.3 V MCU GPIO pin with a 330 Ω series resistor, delivering ~7 mA peak gate current while staying within safe SOA limits.

Is a snubber circuit required for inductive loads like motors?

A snubber is not required for typical fan or pump motors due to the device's 50 V/µs dV/dt rating at 110 °C. However, for highly reactive loads or long cable runs introducing high dv/dt transients, a 100 Ω + 100 nF RC network across MT1–MT2 is recommended for robustness.

How does the SOT-223 package compare thermally to TO-92 for this part?

The SOT-223 offers R_th(j-t) = 25 °C/W versus TO-92's R_th(j-l) = 60 °C/W, enabling ~2.4× higher power dissipation at equal temperature rise. This allows full 1 A RMS current in compact SMT designs where TO-92 would require derating to ~0.6 A in still air.
