The DIOTEC 3.0SMCJ40A is a high-power, unidirectional Transient Voltage Suppressor (TVS) diode, offering exceptional protection against voltage transients. With a peak pulse power dissipation of 3000W and a standoff voltage of 40V, this device effectively clamps overvoltage events, preventing damage to downstream circuitry. Its unidirectional configuration makes it ideal for applications where protection against positive voltage surges is required. The SMC (DO-214AB) package provides excellent thermal performance and allows for efficient board mounting. Typical applications include power supplies, telecommunications equipment, industrial controls, and consumer electronics. Supreme Components International is an authorized distributor of DIOTEC electronic components, ensuring you receive genuine and reliable parts.
