1N5550 thru 1N5554 Available on commercial versions VOIDLESS HERMETICALLY SEALED STANDARD RECOVERY GLASS RECTIFIERS Qualified Levels: JAN, JANTX, JANTXV and JANS Qualified to MIL-PRF-19500/420 DESCRIPTION This “standard recovery” rectifier diode series is military qualified and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 5.0 amp rated rectifiers for working peak reverse voltages from 200 to 1000 volts are hermetically sealed with voidless-glass construction using an internal “Category 1” metallurgical bond. These devices are also available in surface mount MELF package configurations. Microsemi also offers numerous other rectifier products to meet higher and lower current ratings with various recovery time speed requirements including fast and ultrafast device types in both throughhole and surface mount packages.

Derate linearly at 22.2 mA/ºC from +55 ºC to +100 C. 3. These I O ratings are for a thermally (PC boards or other) mounting methods where the lead or end-cap temperatures cannot be maintained and where thermal resistance from mounting point to ambient is still sufficiently controlled where T J(MAX) does not exceed 175 oC. This equates to R θJX ≤ 47 ºC/W. 4. Derate linearly at 26.7 mA/°C above T A = +100 °C to +175 °C ambient.

Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range excluding all transient voltages (ref JESD282-B). Average Rectified Output Current: The Output Current averaged over a full cycle with a 50 Hz or 60 Hz sine-wave input and a 180 degree conduction angle. Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from the forward direction to the reverse direction and a specified decay point after a peak reverse current occurs.
