Product Description
Vishay 1N6278A-E3/54 is a high-performance 1.5 kilowatt (kW) single-element uni-directional transient voltage suppression (TVS) diode with two pins, designed for protecting sensitive electronic components from voltage spikes. It is configured as a single diode element for effective suppression of transients and is mounted through hole in a 1.5KE package, ensuring sturdy installation.
This TVS diode features a minimum breakdown voltage of 19 volts (V), making it optimal for protecting circuits with a maximum operating voltage of 17 V. It delivers a peak pulse power dissipation of 1.5 kW and supports a peak pulse current of up to 54.2 amperes (A), effectively clamping voltage spikes to 27.7 V. The diode is capable of operating across a wide temperature range from -55°C to 175°C, which extends its usability in demanding industrial, automotive, and electronic protection applications.
With a compact form factor of 9.5 mm length and a diameter, width, and height of 5.3 mm, the diode suits space-constrained designs on PCBs and other assemblies. It also meets the AEC-Q101 automotive standard, ensuring reliable performance in automotive electronics. The device provides electrostatic discharge (ESD) protection while maintaining a low maximum reverse leakage current of 1 microampere (μA), enhancing circuit reliability.
Typical applications include electronic circuit protection in automotive systems, industrial electronics, power supplies, and other environments where transient voltage suppression is critical. This diaphragm-like transient voltage suppressor protects sensitive components by absorbing harmful voltage surges and preventing damage.
