SMAJ Transient Voltage Suppressor Diode Series

General Information

The markets of portable communications, computing and video equipment are challenging the semiconductor industry to develop

increasingly smaller electronic components.

Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection applications, in compact chip package DO-214AC (SMA)

size format. The Transient Voltage Suppressor series offers a choice of Working Peak Reverse Voltage from 5 V up to 495 V and Breakdown

Voltage up to 550 V. Typical fast response times are less than 1.0 ns for unidirectional devices and less than 5.0 ns for bidirectional devices

from 0 V to Minimum Breakdown Voltage.

Bourns ? Chip Diodes conform to JEDEC standards, are easy to handle with standard pick and place equipment and the ?at con?guration

minimizes roll away.
