DPDT Surface Mount Relay with internal diode for coil transient suppression
and polarity reversal protection
The Series S422D and S422DD utilize discrete diodes for
coil suppression and polarity reversal protection.
DESCRIPTION
The magnetic-latching TO-5 relay, originally conceived and developed by Teledyne, has become one of the industry standards
for low-level switching from dry circuit to 1 ampere. Designed for
high-density PC board surface mounting, its small size and low coil
power dissipation make the S422 relay one of the most versatile
ultraminiature relays available.
The following unique construction features and manufacturing
techniques provide excellent resistance to environmental extremes
and overall high reliability:
• All welded construction.
• Unique uni-frame design providing high magnetic efficiency and
mechanical rigidity.
• High force/mass ratios for resistance to shock and vibration.
• Advanced cleaning techniques provide maximum assurance of
internal cleanliness.
• Precious metal alloy contact material with gold plating assures
excellent high current and dry circuit switching capabilities.
PRINCIPAL OF OPERATION
PERMANENT MAGNET
MAGNETIC CIRCUIT B
By virtue of its inherently low intercontact capacitance and contact
circuit losses, these TO-5 relays have proven to be excellent ultraminiature RF switches for frequency ranges well into the UHF spectrum. A typical RF application for these TO-5 relays is in
handheld radio receivers, wherein the combined features of good RF
performance, small size, very low coil power dissipation and high reliability make it a preferred method of transmit-receive
switching (See Figure 1).
The Series S422 magnetic-latching relays are ideally suited for
applications where power dissipation must be minimized. The relays
can be operated with a short duration pulse. After the contacts have
transferred, no external holding power is required.
The magnetic latching feature of the Series S422 relays provide a
“memory” capability, since the relays will not reset upon removal of
coil power.

net, becomes great enough to break the armature
free of Core B, and snap it into a closed position
against Core A. The armature then remains in this
MOVING
CONTACT
position upon removal of power from Coil B, but
will snap back into position B upon energizing Coil
A. Since operation depends upon cancellation of a magnetic field, it is necessary to apply
the correct polarity to the relay coils as indicated on the relay schematic. When latching
relays are installed in equipment, the latch and reset coils should not be pulsed simultaneously. Coils should not be pulsed with less than rated coil voltage and the pulse width
should be a minimum of three times the specified operate time of the relay. If these conditions are not followed, it is possible for the relay to be in the magnetic neutral position.
