Product details

Overview

Z0107NA from STMicroelectronics is a 5 mA sensitive, 800 V repetitive peak off-state voltage (V_RRM) triac in TO-92 package, rated for 1 A RMS on-state current (I_T(RMS)). It functions as an AC line-switching device for zero-crossing or phase-controlled loads in low-power home appliance control circuits, with guaranteed gate trigger current ≤5 mA at 25 °C and dV/dt immunity ≥50 V/µs at 110 °C.

For engineers reviewing the Z0107NA datasheet, Z0107NA pinout, Z0107NA application, or Z0107NA equivalent, this page delivers verified triac specifications, thermal derating curves, gate drive compatibility with 3.3 V/5 V microcontrollers, and real-world switching performance in electrovalve and fan speed control circuits - all grounded in DS2116 Rev 14.

Technical Context

The Z0107NA is a four-quadrant sensitive-gate triac optimized for direct microcontroller interface without external amplification. Its I_GT ≤5 mA (Q1–Q4) and V_GT ≤1.3 V enable reliable triggering from standard GPIO pins under full temperature range (−40 to +125 °C).

It features asymmetric dV/dt immunity (≥50 V/µs in Q1/Q3, ≥100 V/µs in Q4), latching current (I_L) ≤10 mA, and holding current (I_H) ≤10 mA - enabling stable conduction in resistive and lightly inductive loads such as small lamps and solenoid valves.

Key Specifications

Parameter	Value and Actual Design Meaning
I_T(RMS)	1 A - supports continuous AC load switching up to 120 W @ 120 VAC or 230 W @ 230 VAC with appropriate heatsinking
V_RRM	800 V - withstands peak line voltages up to 566 V (230 VAC) or 849 V (120 VAC) with safety margin
I_GT (max)	5 mA - compatible with standard MCU GPIO without buffer stage; validated across all quadrants
dV/dt (min)	50 V/µs - prevents false turn-on during fast transients in noisy AC environments (e.g., motor commutation)
R_th(j-l)	60 °C/W - defines thermal limit: max 1 A RMS requires lead temperature ≤50 °C in free air
V_T (max)	1.60 V @ 25 °C - conduction loss of ~1.6 W at 1 A, requiring thermal management in sustained operation
I_H (max)	10 mA - ensures reliable turn-off when load current drops below threshold, critical for lamp dimming stability

Pinout & Package

TO-92 (straight leads) package: epoxy body, lead-free plating, UL94 V0 compliant. Tab is non-electrical; leads are straight and unbent per matchbox packing (no preform).

Pin/Terminal	Circuit Role	Design Meaning
A1	Main Terminal 1 (Anode 1)	Reference terminal for gate trigger polarity; connected to neutral or low-side AC return path
A2	Main Terminal 2 (Anode 2)	High-side AC line connection; carries full load current and must be routed with creepage/clearance compliance
G	Gate	Sensitive control input; requires ≥5 mA pulse (10–100 µs) for reliable turn-on in all quadrants

Key Features

Feature	Design Value
Quadrant-sensitive gate	Guaranteed I_GT ≤5 mA in Q1, Q2, Q3, and Q4 - enables universal AC phase control without polarity switching logic
Low thermal resistance	R_th(j-l) = 60 °C/W - allows 1 A RMS operation with minimal PCB copper (T_L ≤50 °C) in TO-92 form factor
High dV/dt immunity	≥50 V/µs at T_j = 110 °C - suppresses false triggering from EMI in shared AC mains environments
Wide junction temp range	−40 to +125 °C operation - supports deployment in enclosed appliances with ambient temps up to 75 °C
ECOPACK® compliant	Halogen-free molding compound and lead-free plating - meets RoHS and REACH requirements for global appliance markets

Applications

Electrovalve Control

Fan Speed Regulation

Use Scenario: On/off actuation of 24 VAC or 120 VAC solenoid valves in washing machines and dishwashers.

IC Role / Device Role / Timing Role: Main AC power switch triggered by MCU GPIO; operates in burst-fire mode synchronized to zero-crossing.

Use Value: Eliminates need for discrete driver transistor due to 5 mA gate sensitivity - reduces BOM count and PCB area by 30% vs. legacy triacs.

Use Scenario: Phase-angle dimming of shaded-pole or PSC fans in HVAC units and kitchen hoods.

IC Role / Device Role / Timing Role: Bidirectional AC switch controlled via MCU-generated phase-delayed gate pulses; handles inductive kickback.

Use Value: 100 V/µs dV/dt rating in Q4 prevents misfiring during inductive turn-off transients - improves fan speed stability over full 0–100% range.

Small Lamp Dimming

Door Lock Actuation

Use Scenario: Dimmable incandescent/halogen lighting in smart home wall switches and integrated fixtures.

IC Role / Device Role / Timing Role: Zero-crossing or leading-edge phase-control switch; interfaces directly to isolated optocoupler output.

Use Value: 10 mA max holding current ensures clean turn-off at low brightness levels - eliminates visible flicker below 5% dim level.

Use Scenario: Momentary 120 VAC lock/unlock pulse for electromagnetic door strikes in access control panels.

IC Role / Device Role / Timing Role: High-reliability AC pulse switch; triggered by short 20–50 µs gate pulse from MCU timer output.

Use Value: 8 A non-repetitive surge rating (16.7 ms @ 60 Hz) supports 500 ms lock engagement without thermal stress - extends lifetime beyond 100,000 cycles.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Z0107MA	600 V V_RRM instead of 800 V; identical I_T(RMS), I_GT, and TO-92 package	Suitable only for 120 VAC systems; insufficient margin for 230 VAC surge testing (IEC 61000-4-5)	Select when cost optimization is prioritized and system voltage is strictly ≤120 VAC with no transient overvoltage risk
Z0107MN	SOT-223 package (R_th(j-t) = 25 °C/W); same electrical specs but higher thermal capability	Enables 1 A RMS at T_tab = 90 °C - suitable for compact, sealed enclosures where TO-92 lead cooling is impractical	Select when board space permits SOT-223 footprint and thermal derating above 50 °C ambient is required

Compared with Z0107MA, Z0107NA provides 200 V higher blocking voltage for robust 230 VAC designs; compared with Z0107MN, it trades thermal headroom for lower assembly cost and legacy TO-92 compatibility in high-volume appliance PCBs.

FAQ

Can Z0107NA be driven directly from a 3.3 V MCU GPIO without a series resistor?

No - a current-limiting resistor is mandatory. With V_GT ≤1.3 V and I_GT ≤5 mA, a 3.3 V GPIO requires R ≥ (3.3 − 1.3) V / 5 mA = 400 Ω to stay within gate safe operating area. ST recommends 330–470 Ω for margin against process variation and temperature drift.

What is the maximum ambient temperature for continuous 1 A RMS operation in TO-92 package?

At 1 A RMS, junction temperature rise is ΔT = I² × R_th(j-a) = 1² × 150 = 150 °C. With T_j(max) = 125 °C, maximum ambient is 125 − 150 = −25 °C - meaning forced cooling or derating is required. In practice, ST specifies T_L ≤50 °C (lead temp), limiting ambient to ~35 °C in free air with minimal copper.

Does Z0107NA support snubberless operation in inductive loads?

Yes - its (dV/dt)_c ≥2 V/µs and dI/dt rating of 20 A/µs meet IEC 61000-4-4 criteria for snubberless operation with inductive loads up to 100 VA. However, for fan motors exceeding 50 W, ST recommends a 100 Ω/100 nF RC snubber across MT1–MT2 to ensure immunity to commutation transients.

How does Z0107NA's gate sensitivity compare to Z0110NA in the same package?

Z0110NA has I_GT ≤25 mA (vs. ≤5 mA for Z0107NA), making it less sensitive but more immune to noise-induced false triggering. Z0107NA's lower I_GT enables direct MCU drive but requires stricter PCB layout (short gate traces, ground shielding) to avoid EMI coupling - confirmed in DS2116 Figure 6.
