PM20CNJ060

The PM20CNJ060 has some maximum ratings (Tj = 25, unless otherwise noted).When parameter is collector-emitter voltage,the symbol is VCES,the condition is VD = 15V, VCIN = 15V,the ratings is 600,the unit is V.When parameter is collector current,the symbol is ±IC,the condition is TC = 25,the ratings is 20,the unit is A.When parameter is collector current(peak),the symbol is ±ICP,the condition is TC = 25,the ratings is 40,the unit is A.When parameter is collector dissipation,the symbol is PC,the condition is TC = 25,the ratings is 56,the unit is W.When parameter is junction temperature,the symbol is Tj,the ratings is -20 to +125,the unit is .

The item defines the maximum junction temperature for the power elements (IGBT/Diode) of the IPM to ensure safe operation. However,these power elements can endure junction temperature as high as 150°C instantaneously. To make use of this additional temperature allowance,a detailed study of the exact application conditions is required and, accordingly, necessary information is requested to be provided before use.

Design the PCB pattern to minimize wiring length between opto-coupler and IPM's input terminal, and PM20CNJ060 also to minimize the stray capacity between the input and output wirings of opto-coupler.Connect low impedance capacitor between the Vcc and GND terminal of each fast switching opto-coupler.Fast switching opto-couplers:tPLH, tPHL 0.8s, Use High CMR type.Slow switching opto-coupler:CTR > 100%.Use 4 isolated control power supplies (VD). Also, PM20CNJ060 should be taken to minimize the instantaneous voltage charge of the power supply.Make inductance of DC bus line as small as possible, and minimize surge voltage using snubber capacitor between P and N terminal.Use line noise filter capacitor (ex. 4.7nF) between each input AC line and ground to reject common-mode noise from AC line and improve noise immunity of the system.
