STMicroelectronics Z00607MA 5BL2

Overview

Z00607MA 5BL2 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 control, and fan speed controllers. It supports direct microcontroller drive due to its low I_GT, operates up to 110 °C junction temperature, and features 10 V/µs dV/dt immunity at 110 °C.

For engineers reviewing the Z00607MA 5BL2 datasheet, Z00607MA 5BL2 pinout, Z00607MA 5BL2 application, or Z00607MA 5BL2 equivalent, key selection criteria include RMS on-state current (0.8 A), repetitive peak off-state voltage (600 V), gate trigger current (5 mA), thermal resistance (150 °C/W junction-to-ambient), and TO-92 tape-and-reel packaging (5BL2).

Technical Context

The Z00607MA 5BL2 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 drive from 3.3 V or 5 V GPIOs without external amplification, while its 10 V/µs dV/dt rating ensures robustness against false triggering in noisy mains environments.

It exhibits 1.5 V maximum on-state voltage at 1.1 A and 25 °C, with dynamic resistance of 420 mΩ at 110 °C - enabling low conduction loss in thermally constrained TO-92 layouts. The device's 9 A non-repetitive surge rating (20 ms, 50 Hz) supports brief motor-start or inrush events in appliance loads.

FAQ

What is the maximum junction temperature for Z00607MA 5BL2?

The maximum operating junction temperature is +110 °C, as specified in Table 1 of the official datasheet (DocID6629 Rev 9). This rating applies under defined thermal conditions including TO-92 lead temperature ≤50 °C and proper PCB copper area. Exceeding this temperature risks parametric shift and premature failure.

Can Z00607MA 5BL2 be driven directly by a 3.3 V microcontroller GPIO?

Yes - with I_GT ≤5 mA and V_GT ≤1.3 V, a 3.3 V GPIO sourcing ≥5 mA (e.g., STM32, ESP32, or PIC with strong output) can trigger the triac directly using a series current-limiting resistor (typically 330 Ω to 470 Ω), verified in Figure 2 and Table 2 of the datasheet.

Does Z00607MA 5BL2 require a snubber circuit in typical fan control applications?

A snubber is not mandatory for resistive or lightly inductive loads like small fans if dV/dt remains below 10 V/µs. However, for highly inductive motors or long cable runs, a basic RC snubber (e.g., 100 Ω + 100 nF) is recommended to suppress voltage spikes exceeding the 600 V VDRM rating, per application guidance in ST AN437.

What does "5BL2" mean in the part number Z00607MA 5BL2?

"5BL2" is ST's packing code indicating TO-92 package delivered in tape-and-reel format with 2000 units per reel. Per Table 7 and Figure 9 in DocID6629 Rev 9, "5" = TO-92, "B" = tape-and-reel, "L2" = reel size variant - distinct from "1BA2" (bulk) or "2BL2" (ammo pack).
