Features
Standard options : short circuit/overload
protection and control status.
Tested per MIL-R-28750 and approved to
DESC dwg 90091.
Optically coupled all solid state relay
TTL & CMOS compatible input
Low on-resistance power MOSFET output
All versions available with CII “W” level
screening.
The DS13 series SSRs employ state of the art photo-voltaic optical isolation and power MOSFET output chips for
ultra-reliable high speed switching of DC loads up to 2 amps, with low on-resistance. Standard options include
integral current overload/short circuit protection and a separate input control status line. The overload feature
provides protection of the relay, load, and load circuit wiring in the event of a sustained current overload or short
circuit while the relay is on or when it is tu rned on into a short. The control status provides a built-in test function
which provides a logic (0) when the input circuit is energized and functional. The relay is packaged into a custom
hermetically sealed low profile 8-pin ceramic DIP package, with optional through hole or surface mount pins.

Notes
Outline Dimensions
1. 2 terminal input configuration is compatible with CMOS or open collector TTL (with pull-up resistor). For
Vcc levels above 6 Vdc, a series limiting resistor is required. See Figure 2 for resistor value. Use standard
resistor value equal to or less than value from curve.
2. Vcc = 5 Vdc for all tests unless otherwise specified.
3. All DS13 Series relays may drive loads connected to either positive or negative referenced power supply
lines. Reversing polarity of output may cause perma nent damage. Inductive loads must be diode suppressed.
4. Transient blocking voltage & electrical system spike tests are performed per MIL-STD-704 (28 Vdc systems).
5. To determine the maximum on-resistance at any given junction temperature, multiply on-resistance at 25°C
by normalized on-resistance factor from curve (Figure 4).
6. Overload testing per MIL-R-28750 is constrained to the limits imposed by the short circuit protection require-
ments of this specification and DESC drawing 90091. Load circuit series inductance for “load shorted” mode
of operation to be limited to 50 mH max. Maximum repetition rate into a shorted load should not exceed 10Hz.
To calculate maximum on-resistance at any temperature, use following equation : R(on) = R(on) @ 25°C x NF
(without short circuit protection) and R(on) = 0.2 x NF + .21 (with short circuit protection) where NF =
normalized on-resistance factor from Figure 4.
7. Proper operation of the status feedback requires a s tatus pull-up resistor. Select the status resistor such that it
limits status output current to 2mA : R status = V status - 0.3V / 2mA.
