Panasonic is part of a large worldwide groupselling relays and associated switching products under different brand names in different territories.The conditions of use in some territories may differ from those customary in Europe. In particular there are often major differences in regard to national and international specifications, such as UL, CSA, VDE, SEV, EVE, SEMKO, etc. Thus, when considering contact loads as stated in this catalogue (e.g. 10 A, 30 VDC for the SP relay) its hould be understood that these values are not necessarily an absolute maximum but tested ratings. Mostly the stated value has been tested for a certain life expectancy as stated by the manufacturer or the respective test house. Thus, under different conditions, the stated “maximum” may, in practice, be safely exceeded.
PhotoMOS and Solid State Relays
Introduction PhotoMOS and Solid State Relays
What makes PhotoMOS relays successful?
Modern sem iconductor technology enables fast,
quiet, bounce-free switching, even miniature
sizes. This
arrangem ent allows PhotoMOS relays switch
both and loads. Moreover, they are extremely
reliable, unaffected vibrations, and their
ON-resistance remains stable throughout their
entire lifetime.31mA)
• Low output capacitance (RF type 1pF)
• Absolute minimum leakage current (pA)
• Extremely long lifetime
• Stable ON-resistance over the entire lifetime
• Extremely compact design (VSSOP, SON, SSOP, SOP)
• contact bounce
• Highly resistant shock and vibration
• Flexible mounting orientation
.
PhotoM relays nevertheless enjoy an
almost unlimited lifetime used according to
the specifications. trigger circuit, the solar
cell’s output voltage controls the gates two
source-coupled OSFETs the output. Light emitted
from LED the input side passes through
an isolator perm eable light and detected
by solar cell.
