T1635H-6T

STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB

T1635H-6T from STMicroelectronics, in a TO-220AB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Main terminal A1 (reference terminal for A2 and gate); the on-state is rated 16 A RMS (IT(RMS)) with VDRM/VRRM of 600 V.
2 A2 passive Main terminal A2, which is also connected to the metal tab on the non-insulated TO-220AB; it is rated 16 A RMS at Tc = 130 °C and 600 V VDRM/VRRM.
3 G input Gate trigger input; the maximum gate trigger current IGT is 35 mA for the T1635H (VD = 12 V, RL = 33 Ω), the maximum VGT is 1.0 V, and the peak gate current IGM is 4 A (tp = 20 µs).
