ROHM Semiconductor ESDxxVFM Transient Voltage Suppressors

ROHM Semiconductor ESDxxVFM Transient Voltage Suppressors are high-reliability, small-mold devices featuring a silicon epitaxial planar structure. These devices deliver a maximum reverse standoff voltage (VRWM) rating between 5V and 30V. At tp = 8/20µs. These provide a peak pulse power (Ppp) of 110W to 200W and a peak pulse current (Ipp) of 2.3A to 12A. These devices also achieve a maximum breakdown voltage (VBR) from 7.48V to 38.64V. Engineers choose these ROHM Semiconductor Transient Voltage Suppressors to protect applications against ESD.
