Intelligent Power Module and Gate Drive Interface, Hermetically Sealed Optocoupler

Currently Viewing:

The DLA SMD 5962-9685201Kxx is a Class K hermetically sealed optocoupler in an 8-Pin ceramic DIP package with the highest level of reliability. Gold plated leads, solder dipped leads and various lead form options are also available. See the datasheet for details.

The 5962-9685201Kxx is manufactured and tested on a MIL-PRF-38534 certified line and included in the DLA Qualified Manufacturers List QML-38534 for Hybrid Microcircuits. The product is capable of operation and storage over the full military temperature range and may also be purchased as either commercial grade or with full MIL-PRF-38534 Class H level testing on the same DLA Standard Microcircuit Drawing (SMD).

The device consists of a GaAsP LED optically coupled to an integrated high gain photodetector. Minimized propagation delay difference between devices make these optocouplers excellent solutions for improving inverter efficiency through reduced switching dead time. An on-chip 20 kohm output pull-up resistor can be enabled by shorting pins 6 and 7, eliminating the need for an external pull-up resistor in common IPM applications. Specifications and performance plots are contained in the datasheet for typical IPM applications.
