SM4T33A

SM4T33 : Transil diodes provide high overvoltage protection by clamping action. Their instantaneous reponse to transients makes them praticularly suited to protect voltage sensitive devices such as MOS Technology and low voltage supplied IC’s. . . . . . MECHANICAL CHARACTERISTICS Body marked with : Logo, Date Code, Type Code and Cathode Band (for unidirectional types only). Full compatibility with both gluing and paste soldering technologies. Excellent on board stability. Tinned copper leads. High temperature resistant resin. ABSOLUTE RATINGS (limiting values) Symbol Pp P Parameter Peak pulse power dissipation See note 1 and derating curve Fig 1. Power dissipation on infinite heatsink See note 1 a.

SM4T33AY : The SM4TY series are designed to protect sensitive automotive circuits against surges defined in ISO 7637-2 and against electrostatic discharges according to ISO 10605. The Planar technology makes it compatible with high-end circuits where low leakage current and high junction temperature are required to provide long term reliability and stability. SM4TY devices are packaged in SMA (SMA footprint in accordance with IPC 7531 standard).
