90 V/1.0 Ohm, Hermetically Sealed, Power MOSFET Optocoupler
The HSSR-7111 is a high reliability Class H single channel hermetically sealed power MOSFET optocoupler in an 8-Pin DIP ceramic package with gold plated leads. Solder dipped leads and various lead form options are also available. See data sheet for details.
The device operates exactly like a solid-state relay. The product is capable of operation and storage over the full military temperature range and may also be purchased as a commercial grade (HSSR-7110) or as a Class H from the DSCC Standard Microcircuit Drawing (SMD) 5962-93140.
The HSSR-7111 is manufactured and tested on a MIL-PRF-38534 certified line and is included in the DSCC Qualified Manufacturers List, QML-38534 for Hybrid Microcircuits. Each device contains an AlGaAs light emitting diode optically coupled to a photovoltaic diode stack which drives two discrete power MOSFETs. The device operates as a solid-state replacement for single-pole, normally open, (1 Form A) relays used for general purpose switching of signals and loads in high reliability applications.
The devices feature logic level input control and very low output on-resistance, making them suitable for both ac and dc loads. Connection A, as shown in the datasheet Functional Diagram, allows for the device to switch either ac or dc loads. Connection B, with the polarity and pin configurations as shown in the datasheet, allows the device to switch dc loads only. The advantage of Connection B is that the on-resistance is significantly reduced, and the output current capability increases by a factor of two.
The HSSR-7111 is a convenient replacement for mechanical and solid state relays where high component reliability with standard footprint lead configuration is desirable.
This product is designed to switch loads on 28 Vdc power systems. They meet 80 V surge and /- 600 V spike requirements.
