REVERSE VOLTAGE 20 1471 PARAMETER TEST METHODS . Lg, SERIES INDUCTANCE Ls, is determined from the self resonant frequency and the junction capacity of the device. Le= 1 S72 C res J . CT, DIODE CAPACITANCE (CT = Cc + CJ). CT is measured at 1.0 MHz using a capacitance bridge (Boonton Electronics Model 75A or equivalent). . TR, TUNING RATIO TR is the ratio of CT measured at 2:0 Vde divided by CT measured at 20 Vdc or at 15 Vdc. . O, FIGURE OF MERIT Q is catculated by taking the G and C readings of an ad- mittance bridge at the specified frequency and substituting in the following equations: anfc ="G {Boonton Electronics Model 33AS9 with range extender or equivalent).MV 1652/1654/1656/1658/1660/1662/ 1664/1666 (continued) ELECTRICAL CHARACTERISTICS (1, = 25C unless otherwise noted) Characteristic Symbol Min Typ Max Unit Reverse Breakdown Voltage BV, Vde (Ip = 10 wdc) MV1652 thru MV1660 20 - - MV1662 thru MV1666 15 - - Reverse Current In pAde (Vp = 15 Vde) MV 1652 thru MV1660 - - 0.1 (Vp = 10 Vdc) MV1662 thru MV1666 - - 0.1 Series Inductance MV1682 thru MV 1666 Lg - 5.0 - nH C,, Diode Capacitance Q, Figure of Merit Capacitance Ratio .
