Product details

Overview

Z00607MA 1BA2 from STMicroelectronics is a standard 0.8 A, 600 V triac in TO-92 package with 5 mA gate trigger current, designed for low-power AC switching in home appliance control circuits such as electrovalves, small lamp dimmers, and door locks. It supports direct microcontroller gate drive and operates across -40 °C to +110 °C junction temperature.

For engineers reviewing the Z00607MA 1BA2 datasheet, Z00607MA 1BA2 pinout, Z00607MA 1BA2 application, or Z00607MA 1BA2 equivalent, key selection criteria include repetitive peak off-state voltage (600 V), on-state RMS current (0.8 A), gate trigger current (5 mA), critical dV/dt immunity (10 V/µs at 110 °C), and thermal resistance (150 °C/W junction-to-ambient).

Technical Context

The Z00607MA 1BA2 is a four-quadrant sensitive-gate triac optimized for zero-crossing–free phase-control and random-turn-on AC switching. Its 5 mA I_GT enables direct TTL/CMOS logic-level triggering without external amplification, while its 10 V/µs dV/dt rating ensures robustness against false turn-on in noisy mains environments.

Thermal performance is defined by R_th(j-l) = 60 °C/W (junction-to-lead) and maximum T_j = +110 °C, requiring minimal heatsinking in TO-92-mounted applications up to 0.8 A RMS. The device exhibits symmetrical conduction in all quadrants, with latching current ≤10 mA and holding current ≤5 mA at 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
IT(RMS)	0.8 A - Maximum continuous AC load current at TL = 50 °C, suitable for small solenoids and lamps
VDRM / VRRM	600 V - Peak repetitive blocking voltage in both directions, compatible with 230 VAC mains with margin
IGT	5 mA max - Gate trigger current in Quadrants I, II, III; enables direct MCU GPIO drive
dV/dt	10 V/µs min at Tj = 110 °C - Immunity to voltage transients without snubber
VTM	1.5 V max at ITM = 1.1 A - Low conduction loss, reducing thermal stress in TO-92 package
Rd	420 mΩ max at Tj = 110 °C - Dynamic on-resistance defining power dissipation under load
I²t	0.45 A²s - Fusing energy limit for 10 ms surge, supporting basic overcurrent protection design

Pinout & Package

Package: TO-92 (3-lead plastic through-hole), lead material: lead-free, compliant with UL94 V0 epoxy.

Pin/Terminal	Circuit Role	Design Meaning
A1 (Anode 1)	Main terminal 1	Reference electrode for gate triggering; connected to neutral or lower-potential AC line side
A2 (Anode 2)	Main terminal 2	Load-side connection; polarity reversal relative to A1 defines quadrant conduction behavior
G (Gate)	Control input	Sensitive gate requiring ≤5 mA to initiate conduction in all four quadrants

Key Features

Feature	Design Value
Low gate trigger current	5 mA max - Eliminates need for gate driver transistors in MCU-based controls
High dV/dt immunity	10 V/µs min at 110 °C - Reduces false triggering in EMI-prone appliance environments
Four-quadrant operation	Triggerable with either polarity of A2 relative to A1 - Enables flexible phase-control topologies
Lead-free TO-92 package	UL94 V0 rated epoxy, RoHS-compliant - Meets environmental compliance for consumer electronics

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 600 V VDRM, but 4 A IT(RMS); higher IGT (10 mA); TO-220 package	Requires heatsink above ~0.5 A; unsuitable for TO-92 footprint replacement	Select when higher current handling is needed and board space allows TO-220 mounting
MAC97A6	600 V VDRM, 0.8 A IT(RMS), but 10 mA IGT; TO-92 package	Higher gate drive requirement limits direct MCU compatibility without buffer	Choose only if existing design already uses MAC97A6 and gate drive circuitry is fixed

Compared with BT134-600E and MAC97A6, the Z00607MA 1BA2 uniquely balances ultra-low gate drive (5 mA), TO-92 form factor, and 600 V rating-making it optimal for space-constrained, microcontroller-driven AC loads under 0.8 A.

FAQ

What is the maximum junction temperature for Z00607MA 1BA2?

The maximum operating junction temperature is +110 °C, as specified in Table 1 of the datasheet. This rating applies under steady-state conditions with TO-92 leads mounted on standard FR4 PCB. Exceeding this temperature risks parametric shift and reduced lifetime, especially under sustained 0.8 A RMS load.

Can Z00607MA 1BA2 be used with 115 VAC systems?

Yes - its 600 V repetitive peak off-state voltage provides ample margin for 115 VAC (peak ≈ 163 V) and 230 VAC (peak ≈ 325 V) systems. The device's dV/dt immunity (10 V/µs) and symmetric four-quadrant triggering make it suitable for global dual-voltage appliance designs without hardware change.

Is a snubber circuit required for Z00607MA 1BA2?

A snubber is not mandatory for resistive loads due to the device's 10 V/µs dV/dt rating, but recommended for inductive loads (e.g., motors, solenoids) to suppress voltage spikes during turn-off. Typical RC snubber values are 100 Ω + 100 nF, placed across A1–A2, per ST Application Note AN437.

What does the '1BA2' suffix indicate in Z00607MA 1BA2?

The '1BA2' denotes TO-92 package in bulk packaging format (2500 units per bag), per ST's ordering scheme in Figure 9 and Table 7. '1B' = TO-92 bulk, 'A2' = specific carrier variant; this differs from '2BL2' (ammopack) and '5BL2' (tape-and-reel) variants of the same device.
