Small Package, High Energy EoS Suppressor SD32303 thru SD32324

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 (V_C/V_RWM 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.  

Features

• 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 (V_C/V_RWM) < 2.0 typical

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

• Applications

• Voltage bus

• User interface

• Power or peripheral ports

• RS-232 data lines

• Clamps internal energy spikes from switches and relays
