TX02-4400 Interface Transformer General Description The TX-02-4400PI/JI is a dual winding interface transformer designed to be used with the IXYS IXBD4410/IXBD4411chip set. This ISOSMART chip set controls the gates of two Power MOSFETs or IGBTs connected in a half-bridge (phase-leg) configuration. This signal transformer transfers information between the two chips with greater than 2500V (RMS) isolation. The TX02-4400PI is available in the standard 8-pin DIP package (TX02-4400PI) and the 8-pin DIP Gullwing package (TX024400JI) TX02-4400PI Preliminary Data Sheet Symbol Test Conditions Ratings NP:NS Primary to Secondary Turns Ratio 3:1 LP f = 100 kHz (Note 1) 0.97 µH Ls f = 100 kHz (Note 1) 0.1 µH CS f = 100kHz; primary to secondary (Note 1) 0.5 pF VISOL Primary to secondary, 50/60 Hz, RMS, t = 1 minute 2500 V TOP, STG Operating and storage Temperature -55 ... +125 °C TL 1.6 mm (0.063 in) from case for 10 s 300 °C 2 g Weight Notes: 1.
