Small Package, High Energy EoS Suppressor SD32303 thru SD32324

Date:January 02, 2018

SD32303 thru SD32324 is a series of single line, unidirectional, EoS (electrical over-stress) Transient Voltage Suppressors (TVS) packaged in the very small SOD-323 outline.  The SD32303 series has a high peak power rating of 300W despite the very small package outline of the SOD-323.  The stand-off voltage ratings of 3.3, 5, 12, 15 and 24 volts facilitate excellent protection of all common logic and analog IC voltage bus requirements. The SD32303 series has a very tight clamping ratio (VC/VRWM typical < 2) which provides superior transient protection when compared to MOV / MLV type products.  The series is a perfect choice for space constrained applications where a single voltage bus or peripheral device port requires protection.  


 High peak power capability of 300W (8/20μs)

 Broad range of working voltages (3.3, 5, 12, 15 and 24) matches common voltage bus

 Unidirectional protection is ideal for DC voltage bus applications

 Very small package footprint (3.4mm2, typical) and low package profile (1mm, max.)

 Very tight clamping ratio (VC/VRWM) < 2.0 typical

 Very low idle current of 1μA (VR≥12V) for energy efficiency during standby operation



 Voltage bus

 User interface

 Power or peripheral ports

 RS-232 data lines

 Clamps internal energy spikes from switches and relays
