BTA12 and BTB12 series. Exemple BT A 12 - 600 BW RG.

A = insulated. B = non insulated.

12 = 12A

600 = 600V 800 = 800V

Sensitivity and type. B = 50mA Standard. C = 25mA Standard. SW = 10mA Logic Level. BW = 50mA Snubberless. CW = 35mA Snubberless. TW = 5mA Logic Level.

Packing mode RG = Tube

Available either in through-hole or surface mount packages, the BTA12, BTB12 and T12xx Triac series are suitable for general purpose mains power AC switching. They can be used as ON/OFF function in applications such as static relays, heating regulation or induction motor starting circuit. They are also recommended for phase control operations in light dimmers and appliance motors speed controllers.

The Snubberless™ versions (W suffix and T12xx) are especially recommended for use on inductive loads, because of their high commutation performance. By using an internal ceramic pad, the Snubberless™ series provide an insulated tab (rated at 2500 V RMS ) complying with UL standards (file reference: E81734).

Logic Level BTA12-600TW and BTA12-600SW offer low holding current, ideal to design light dimmers for LED lamps.

mai 2022 plaque à induction de Colline Henry transistor IGBT = H20R1203 tension élevée : 1200V 20A !
marquage IHW20R120R3, racine du nom 20R120R donc SGH20N120RUFDTU chez Fairchild
Ceci semble a priori équivalent : chez IXYS : IXA12IF1200PB vendu par RS
(IXYS aussi a des références qui commencent par “I” comme Infineon et International Rectifier).
Laurent : IXYS est une marque que je fuis. D'expérience j'ai l'impression que la qualité est moindre que chez ST, IR, Infineon ou d'autres vieilles marques comme Fairchild.

IHW30N120R5 de Infineon, marqué H30MR5, chez RS et datasheet : pas mieux, dixit Laurent. Commandé (x30) le 1er septembre 2022.
