Bourns SMAJ33A Transient Voltage Suppressor Diode

The SMAJ series Transient Voltage Suppressor Diodes are designed for surge and ESD protection applications. They offer a working peak reverse voltage range from 5V to 495V and a breakdown voltage up to 550V. These devices feature fast response times, with less than 1 picosecond for unidirectional types and less than 5 picoseconds for bidirectional types, from 0V to their minimum breakdown voltage. Conforming to JEDEC standards, they are easy to handle with standard pick-and-place equipment, and their flat configuration helps prevent rolling. The devices support power dissipation up to 400W and operate within a temperature range of -55°C to 150°C. Common applications include communications, networking, computers, imaging, video, vision systems, and industrial equipment. Note that market demand has extended lead times, and delivery dates may fluctuate. These products are exempt from discounts.
