LPBD100 29
LPBD100\072002\Q1
250mA, 100Vdc Normally Closed
Dual Relay
FEATURES/BENEFITS
Compact SIP plastic package
Dual output: two relays in one package
Normally closed output
Low voltage drop
DESCRIPTION
The LPBD100 is a dual-output 100Vdc plastic relay.
The relay output-switch contacts are normally closed
and will conduct the load current until a voltage is
applied to the relay input. With 4 volts or more at the
relay input, the output-switch contacts open and the
relay no longer conducts. The LPBD100 assembly
contains two independent relays, completely isolated
from each other, in a single in-line package (SIP).
The relays provide optical isolation between input and
output terminals. Each relay output circuit uses a pair
of depletion-mode MOSFETs for reliable operation.

NOTES:
1. For input voltages greater than 7 volts, use an external resistor in
series with the relay input. Rext. = (Vin7 Vdc)/0.012 Amps
2. Unless otherwise specified: conformance testing is at room
temperature; the input voltage is 5Vdc or zero volts as required; the
output load is 48Vdc, 0.25 amp.
3. Relay input voltage transitions should be less than 1.0 millisecond.
4. Maximum load current ratings are with the relay in free air and
soldered to a printed circuit board.
5. Timing is measured from the input voltage transition to the 10% or
90% point on the output voltage off-to-on or on-to-off transition. Rise
and fall times are from the 10% to 90% points on the output voltage
transition.
