Power Switching solid state relays 53124
The 53124 is a single channel power MOSFET optocoupler which is suitable as a pin for pin replacement for the Mii 53111 when radiation tolerant performance and similar electrical performance to the 53111 is required. The primary difference between the 53124 and 53111 is that the radiation tolerant power MOSFETs employed in the 53124 exhibit a higher RDS(ON). The higher values of RDS(ON) results in a lower current for the same power dissipation or higher power dissipation for the same current levels relative to the 53111. The popular eight pin, hermetic dual-in-line ceramic package combined with 1500 VDC isolation between input and output, makes this optocoupler ideal for solid-state relay applications. Performance is specified over the full military temperature range. This device is available as COTS, or as fully compliant MIL-PRF-38534 Class H or with custom screening. Lead options support both through-hole and surface-mount assembly. Gold plated leads are standard, but other lead finishes per MIL-PRF-38534 are also available. Functionally, the device operates as a single-pole, normally open (1 Form A) solid-state relay. The device is actuated by an input current, which can be supplied from standard logic types such as open-collector TTL. The input current biases a light emitting diode that is optically coupled to an integrated photovoltaic diode array. The photovoltaic array powers control circuitry that operates the output MOSFETs. Optimum switching of either AC or DC loads is provided by a configurable output. For AC loads, Connection A in Figure 1 must be used. Connection A will also switch DC loads but Connection B, in Figure 1, provides DC-only operation with the advantages of substantial reduction in on-resistance and twice the output current capability as that obtained with Connection A.
