Housed in a TO-251-3 I-PAK through-hole package, it mounts directly into a PCB with short leads, suiting compact board layouts where a TO-220 would overhang the edge. ## Gate drive and temperature envelope Maximum gate trigger current (Igt) is 10 mA and gate trigger voltage (Vgt) is 1.3 V, so a standard 5 V logic output through a current-limiting resistor can fire it — no special driver needed for low-power control circuits. Hold current (Ih) is 10 mA max, meaning the TRIAC latches on once triggered and stays conducting until the load current drops below that threshold — important for inductive loads where the current zero-cross may not align with the gate pulse. Operating junction temperature range is -40°C to 125°C, covering industrial and outdoor equipment enclosures without derating at the high end. ## Lifecycle and compliance Part of the ECOPACK2 series, which means the package materials and plating meet ST's lead-free and halogen-free criteria per their internal green-packaging standard.","metaTitle":"STMicroelectronics Z0409MH TRIAC, 600V 4A I-PAK","metaDescription":"STMicroelectronics Z0409MH standard TRIAC, 600V off-state, 4A RMS, 16A surge, I-PAK through-hole.
