The 50 mA maximum holding current (Ih) ensures the device latches on once triggered and does not drop out on a lightly loaded half-cycle; this matters for low-current loads like small fans or relay coils where the load current dips near the zero crossing. ## Surge current and junction temperature envelope Non-repetitive surge current (ITSM) is rated at 160 A for 50 Hz and 168 A for 60 Hz — the peak current the die can absorb during a fault or inrush event without failing.","metaTitle":"ST BTA16-600BWRG Triac Alternistor, 600 V, 16 A, Snubberless","metaDescription":"STMicroelectronics BTA16-600BWRG Snubberless Alternistor triac, 600 V off-state, 16 A RMS, TO-220-3, -40°C to 125°C.
