QM40-14P-PR1 on stock NOTES FOR STABLE AND SAFE OPERATION ; ~ Design the PCB pattern to minimize wiring length between opto-coupler and IPM's input terminal, and also to minimize the stray capacity between the input and output wirings of opto-coupler. *Quick opto-couplers: TPLH, TPLH < 0.8Us. Use High CMR type. The line between opto-coupler and intelligent module should be shortened as much as possible to minimize the floating capacitance. ,Slow switching opto-coupler: recommend to use at CTR = 100 ~ 200%, Input current = 8 ~ lOmA, to work in active. *Use 4 isolated control power supplies (VD). Also, care 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. Notes (al For a dual device surface mounted on 8 sq cm single sided 20z copper on FR4 PCB, in still air conditions with all exposed pads attached. The copper area is split down the centre line into two separate areas with one half connected to each half of the dual device. (b; Measured at t<5 secs for a dual device surface mounted on 8 sq cm single sided 20z copper on FR4 PCB, in still air conditions with all exposed pads attached. The copper area is split down the centre line into two separate areas with one half connected to each half of the dual device. (c) For a dual device surface mounted on 8 sq cm single sided 20z copper on FR4 PCB, in still air conditions with minimal lead connections only. tdl For a dual device surface mounted on 10 sq cm single sided loz copper on FR4 PCB, in still air conditions with all exposed pads attached attached. The copper area is split down the centre line into two separate areas with one half connected to each half of the dual device. (el For a dual device surface mounted on 85 sq cm single sided 20z copper on FR4 PCB, in still air conditions with all exposed pads attached attached. The copper area is split down the centre line into two separate areas with one half connected to each half of the dual device. (fl For a dual device with one active die. (gl For dual device with 2 active die running at equal power. (hj Repetitive rating - pulse width limited by max junction temperature. Refer to Transient Thermal Impedance graph. (il The minimum copper dimensions required for mounting are no smaller than the exposed metal pads on the base of the device as shown in the package dimensions data. The thermal resistance for a dual device mounted on l.5mm thick FR4 board using minimum copper l oz weight, Imm wide tracks and one half of the device active is Rth = 2500C/W giving a power rating of Ptot = 400mW. |
