DESIGNATION
RELAY TYPE
DPDT general-purpose magnetic-latching relay with internal power
MOSFET driver and diode coil transient suppression
122C
The Series 122C relay has internal silicon diodes for coil
suppression, Zener diodes to protect the MOSFET gate inputs, and
N-channel enhancement-mode MOSFET chips, which enable direct
relay interfacing with most microprocessor and IC logic families
(CMOS, TTL and MOS).
DESCRIPTION
The 122C Centigrid® magnetic-latching relay is an ultraminiature,
hermetically sealed, armature relay capable of being directly driven
by most IC logic families. Its low profile height and .100” grid spaced
terminals, which precludes the need for spreader pads, make it ideal
for applications where extreme packaging density and/or close PC
board spacing are required.
The 122C magnetic-latching relay is ideally suited for applications
where coil operating power must be minimized. The relays can be
operated with a short-duration pulse. After the contacts have
transferred, no external coil power is required.
The basic operating function and internal structure are similar to
Teledyne’s TO-5, 422 relay series. The 122C is capable of meeting
Teledyne Relays’ T2R® requirements. The following unique
construction features and manufacturing techniques provide overall
high reliability and excellent resistance to environmental extremes:
The magnetic-latching feature of the Series 122C relay provides a
“memory” capability, since the relays will not reset upon removal of
coil power.
• All welded construction.
• Unique uni-frame design providing high magnetic efficiency and
mechanical rigidity.
• High force/mass ratios to withstand 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.
By virtue of its inherently low intercontact capacitance and contact
circuit losses, the 122C relay has proven to be an excellent
ultraminiature RF switch for frequency ranges well into the UHF
spectrum. A typical RF application for this Centigrid® relay is in
handheld radio transceivers, wherein the combined features of good
RF performance, small size, low coil power dissipation and high
reliability make it a preferred method of transmit-receive switching
(see Figure 1).

PRINCIPLE OF OPERATION
MAGNETIC CIRCUIT B
Energizing Coil B produces a magnetic field
opposing the holding flux of the permanent
magnet in Circuit B. As this net holding force
decreases, the attractive force in the air gap of
Circuit A, which also results from the flux of the
permanent magnet, becomes great enough to

armature then remains in this position upon removal of energy from Coil B, but will snap
back to 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 magnetically neutral position.
