BTA16-800B Triac 800V 16A TO-220AB

From the shop's description

BTA16-800B — 16A RMS, 800V Standard Triac (50mA Gate Sensitivity), TO-220AB Insulated Package The BTA16-800B is a medium-current TRIAC from STMicroelectronics, suitable for general purpose mains power AC switching . It can be used as an ON/OFF function in applications such as static relays, heating regulation or induction motor starting circuits. It is also recommended for phase control operations in light dimmers and appliance motor speed controllers. This is the insulated tab version (BTA series) featuring an internal ceramic pad, with the tab rated at 2500 V RMS , complying with UL standards. The “B” suffix denotes the standard sensitivity version (I GT = 50 mA) with 4-quadrant triggering capability. Features Medium current Triac Low thermal resistance with clip bonding Low thermal resistance insulation ceramic for insulated BTA High commutation (4Q) capability Insulated tab rated at 2500 V RMS Specifications Product Summary Parameter Value I T(RMS) — RMS on-state current 16 A V DRM /V RRM — Repetitive peak off-state voltage 800 V I GT — Gate trigger current (standard) 50 mA Absolute Maximum Ratings Symbol Parameter Conditions Value Unit I T(RMS) RMS on-state current (full sine wave) TO-220AB Ins., T C = 86 °C 16 A I TSM Non-repetitive surge peak on-state current (full cycle, T j initial = 25 °C) f = 50 Hz, t p = 20 ms 160 A I TSM Non-repetitive surge peak on-state current f = 60 Hz, t p = 16.7 ms 168 A I²t I²t value for fusing t p = 10 ms 144 A²s dI/dt Critical rate of rise of on-state current I G = 2 × I GT , t r ≤ 100 ns, f = 120 Hz, T j = 125 °C 50 A/µs V DSM /V VRSM Non-repetitive surge peak off-state voltage t p = 10 ms, T j = 25 °C V DRM /V RRM + 100 V I GM Peak gate current t p = 20 µs, T j = 125 °C 4 A P G(AV) Average gate power dissipation T j = 125 °C 1 W T stg Storage junction temperature range — -40 to +150 °C T j Operating junction temperature range — -40 to +125 °C Static Electrical Characteristics Symbol Test Conditions T j Value Unit V T I TM = 22.5 A, t p = 380 µs 25 °C Max. 1.55 V V TO Threshold on-state voltage 125 °C Max. 0.85 V R D Dynamic resistance 125 °C Max. 25 mΩ I DRM /I RRM V DRM = V RRM 25 °C Max. 5 µA I DRM /I RRM V DRM = V RRM 125 °C Max. 2 mA Note: For both polarities of A2 referenced to A1.
