Bourns SMA6J18A is a high-performance 1-element uni-directional ESD Protection Diode designed in a compact surface mount DO-214 package. It provides reliable transient voltage suppression with a 600 W peak pulse power dissipation rating and a maximum reverse stand-off voltage of 43 V. This diode operates effectively over a wide temperature range from -55°C up to 150°C, making it suitable for demanding industrial and automotive applications.
The SMA6J18A model features a single element diode configuration that delivers fast transient suppression response times under 1 picosecond, enhancing protection of power buses and sensitive electronic I/O interfaces. Its low maximum reverse leakage current of 1 μA ensures minimal impact on circuit efficiency.
With the AEC-Q101 automotive standard certification, this diode is qualified for use in automotive-grade electronics. The surface mount DO-214 (SMA) package facilitates high-density PCB layouts and reliable automated assembly. The device's compact dimensions (length 4.5 mm, width 2.79 mm, height 2.08 mm) enable integration in space-constrained designs.
Typical applications include protection against overvoltage transients in telecom equipment, computers, industrial controllers, and consumer electronics. The diode safeguards circuits from ESD and surge events, prolonging device lifetimes and enhancing system reliability.
This diode has a single uni-directional element for enhanced protection. A robust surface mount package (DO-214) ensures ease of assembly on PCBs. The device operates within a temperature range of -55°C to 150°C, suitable for various environments.
It provides fast response times less than 1.0 picosecond to transient voltage spikes. The maximum reverse leakage current is only 1 μA, ensuring minimal power loss. Included automotive standard AEC-Q101 gives it reliability for automotive electronics.
The compact dimensions are 4.5 mm length, 2.79 mm width, and 2.08 mm height. Suitable for protecting power buses, I/O interfaces, telecom, computer, industrial, and consumer electronics. EnvMart offers wide selections of semiconductors, including TVS and ESD diodes like the SMA6J18A, trusted for durability and performance in sensitive electronic protection.
