Product details

Overview

Z00607MA 2BL2 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 electrovalves, small lamp controls, and fan speed regulators. It supports direct microcontroller drive due to its low I_GT, operates up to 110 °C junction temperature, and features 20 A/µs dI/dt capability.

For engineers reviewing the Z00607MA 2BL2 datasheet, Z00607MA 2BL2 pinout, Z00607MA 2BL2 application, or Z00607MA 2BL2 equivalent, key selection criteria include RMS on-state current rating (0.8 A), repetitive peak off-state voltage (600 V), gate trigger sensitivity (5 mA), thermal resistance (R_th(j-l) = 60 °C/W), and TO-92 mechanical compatibility for space-constrained PCB layouts.

Technical Context

The Z00607MA 2BL2 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-level drive without external amplification, while the 10 V/µs minimum dV/dt at 110 °C ensures noise-immune operation in noisy appliance environments.

It exhibits symmetrical triggering across all quadrants (I–IV), with latching current ≤10 mA and holding current ≤5 mA at 25 °C, and maintains stable conduction down to T_j = –40 °C. The device uses planar passivated silicon construction and meets UL94 V0 flammability requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
IT(RMS)	0.8 A - maximum continuous AC load current at TL = 50 °C, defining usable power-handling capacity in thermostatically controlled appliances
VDRM / VRRM	600 V - peak repetitive off-state voltage, enabling safe operation on 230 VAC mains with ≥2× safety margin
IGT (Quadrant I–III)	5 mA max - gate trigger current threshold, allowing direct drive from GPIO pins of 3.3 V/5 V microcontrollers
dI/dt (critical)	20 A/µs - minimum rate-of-rise immunity, preventing false turn-on during inductive load commutation
Rth(j-l)	60 °C/W - junction-to-lead thermal resistance, determining required copper area and heatsinking for TO-92 mounting
VTM @ 1.1 A	1.5 V max - on-state voltage drop at 1.1 A, directly impacting conduction loss (P_cond ≈ 1.65 W at full load)
IL / IH	10 mA / 5 mA max - latching and holding currents, defining minimum load current needed to sustain conduction after triggering

Pinout & Package

Package: TO-92 (3-lead plastic through-hole), lead material: lead-free, compliant with RoHS and ECOPACK® standards. Dimensions per Table 7: A = 1.35 mm, B = 4.70 mm, C = 2.54 mm, D = 4.40 mm, E = 12.70 mm, F = 3.70 mm, a = 0.50 mm.

Pin/Terminal	Circuit Role	Design Meaning
A1 (Anode 1)	Main terminal 1	Reference electrode for gate triggering; connected to neutral or low-side AC line in most single-phase configurations
A2 (Anode 2)	Main terminal 2	High-side AC load connection; polarity relative to A1 defines quadrant behavior during triggering
G (Gate)	Control input	Sensitive gate requiring ≤5 mA pulse; referenced to A1; triggers conduction regardless of A2 polarity (4Q operation)

Key Features

Feature	Design Value
Direct microcontroller drive	5 mA I_GT eliminates need for discrete gate driver transistors or optocoupler secondary stages
Four-quadrant triggering	Guaranteed turn-on in all quadrants (I–IV) enables flexible phase-control timing without polarity constraints
High dV/dt immunity	10 V/µs minimum at 110 °C prevents spurious conduction from EMI or inductive kickback in motor-driven loads
Thermal robustness	110 °C max operating junction temperature supports sealed enclosure use in washing machines and HVAC actuators
UL94 V0 epoxy	Flame-retardant encapsulation meets safety compliance for Class II household appliance internal wiring

Applications

IC Role / Device Role / Timing Role: Main AC power switch triggered by MCU PWM or logic-level signal; no zero-crossing synchronization required.

Use Value: Low 5 mA gate drive reduces system BOM count; 0.8 A rating covers typical 12–24 W solenoid loads.

Use Scenario: Phase-angle dimming of universal motors in ceiling fans and exhaust units.

IC Role / Device Role / Timing Role: Random-turn-on triac enabling variable conduction angle control independent of AC zero-crossing.

Use Value: 20 A/µs dI/dt rating prevents commutation failure during motor startup surges.

Use Value: 9 A non-repetitive surge rating handles lock coil inrush; 110 °C Tj allows operation inside thermally insulated enclosures.

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 0.8 A IT(RMS), 600 V VDRM, but 10 mA IGT - requires gate buffer stage	Higher gate drive demand limits direct MCU interface in low-power designs	Select when legacy design uses BT134 footprint and gate drive circuitry already exists
Z0107MN	0.8 A / 600 V / 7 mA IGT in SOT-223 package - lower Rth(j-t) = 25 °C/W but surface-mount only	Requires rework for through-hole replacement; better thermal performance for high-duty-cycle use	Select for new SMT designs needing improved thermal dissipation or higher reliability under sustained load

Compared with BT134-600E and Z0107MN, Z00607MA 2BL2 uniquely balances ultra-low gate drive (5 mA), TO-92 through-hole compatibility, and 600 V isolation - making it optimal for cost-sensitive, space-constrained, microcontroller-driven AC loads below 200 W.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The Z00607MA 2BL2 has a maximum operating junction temperature of +110 °C, verified per Table 1 of the official datasheet (DocID6629 Rev 9). This rating applies under specified thermal conditions: TO-92 package, lead temperature TL = 50 °C, and full sine-wave conduction. Exceeding this limit risks parametric shift and accelerated wear-out.

Can this triac be used with 115 VAC systems?

Yes - the 600 V VDRM rating provides ample margin for 115 VAC nominal systems (peak ≈ 163 V), supporting both North American and Japanese mains voltages. Its 10 V/µs dV/dt immunity and 20 A/µs dI/dt rating ensure stable operation even with inductive loads like small motors or solenoids commonly found in such equipment.

Is a snubber circuit required for resistive loads?

No snubber is required for purely resistive loads such as incandescent lamps or heating elements, as confirmed by ST's application guidance in AN434. However, a basic RC snubber (e.g., 100 Ω + 100 nF) is recommended for inductive loads like fans or pumps to suppress voltage transients exceeding the 600 V VDRM rating during turn-off.

How does the 2BL2 packing mode differ from 1BA2 and 5BL2?

The 2BL2 suffix denotes TO-92 packaging in ammopack format (2000 units per carrier), offering automated pick-and-place compatibility while retaining through-hole mounting. In contrast, 1BA2 is bulk-packed (2500 units, manual handling), and 5BL2 is TO-92 tape-and-reel (2000 units, optimized for high-speed SMT lines with axial feeders).
