JAN1N4942 Microchip

1N4942 1N4946 Qualified Levels: Voidless Hermetically Sealed JAN, JANTX, Available on Fast Recovery Glass Rectifiers and JANTXV commercial versions Qualified per MIL-PRF-19500/359 DESCRIPTION This Series of industry recognized voidless, hermetically sealed fast recovery glass rectifiers are military qualified to MIL-PRF-19500/359 and are ideal for high-reliability applications where a failure cannot be tolerated. They provide a working peak reverse voltage selection from 200 to 600 Volts with a 1.0 amp current rating. They are very robust in hard-glass construction and also use an internal metallurgical bond identified asCategory 1 for high-reliability applications. These devices are similar in ratings to the 1N5615 through 1N5619 series where surface mount MELF package configurations are also available by adding a US suffix (see separate data sheets).

PART NOMENCLATURE JAN 1N4942 (e3) Reliability Level RoHS Compliance JAN = JAN Level e3 = RoHS compliant (available JANTX = JANTX Level on commercial grade only) JANTXV = JANTXV Level Blank = non-RoHS compliant Blank = Commercial JEDEC type number (See Electrical Characteristics table) SYMBOLS & DEFINITIONS Symbol Definition C Capacitance: The capacitance in pF at a frequency of 1 MHz and specified voltage I Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. R Reverse Recovery Time: The time interval between the instant the current passes through zero when changing from t rr the forward direction to the reverse direction and a specified decay point after a peak reverse current occurs. V Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. F V Minimum Breakdown Voltage: The minimum voltage the device will exhibit at a specified current. (BR) Working Peak Reverse Voltage: The maximum peak voltage that can be applied over the operating temperature range V RWM excluding all transient voltages (ref JESD282-B). Also sometimes known as PIV. C Capacitance: The capacitance in pF at a frequency of 1 MHz and specified voltage.
