1N6620US thru 1N6625US VOIDLESS-HERMETICALLYSEALED SURFACE MOUNT ULTRA FAST RECOVERY GLASS RECTIFIERS
SCOTTSDALE DIVISION
DESCRIPTION
This "Ultrafast Recovery" rectifier diode series is military qualified to MIL-PRF19500/585 and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 1.5 to 2.0 Amp rated rectifiers for working peak reverse voltages from 200 to 1000 volts are hermetically sealed with voidlessglass construction using an internal "Category I" metallurgical bond. These devices are also available in axial-leaded packages for thru-hole mounting (see separate data sheet for 1N6620 thru 1N6625). Microsemi also offers numerous other rectifier products to meet higher and lower current ratings with various recovery time speed requirements including standard, fast and ultrafast device types in both through-hole and surface mount packages.

MAXIMUM RATINGS
* Junction Temperature: -65 C to +175 C * Storage Temperature: -65oC to +175oC o * Peak Forward Surge Current @ 25 C: 20 Amps (except 1N6625 which is 15 Amps) Note: Test pulse = 8.3 ms, half-sine wave. * Average Rectified Forward Current (IO) at TEC=+110oC: 1N6620 thru 1N6622: 2.0 Amps 1N6623 thru 1N6625: 1.5 Amps (Derate linearly at 1.5%/oC for TEC > +110oC) o * Average Rectified Forward Current (IO) at TA=25 C: 1N6620 thru 1N6622: 1.2 Amps 1N6623 thru 1N6625: 1.0 Amp (Derate linearly at 0.67%/ oC for TA>+25oC. This IO rating is typical for PC boards where thermal resistance from mounting point to ambient is sufficiently controlled where TJ(max) is not exceeded.) * Thermal Resistance junction to endcap (RJEC): 20oC/W * Capacitance at VR= 10 V: 10 pF o * Solder temperature: 260 C for 10 s (maximum)

Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current. Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range. 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. Capacitance: The capacitance of the TVS as defined @ 0 volts at a frequency of 1 MHz and stated in picofarads. 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 recovery decay point after a peak reverse current is reached.
