Product Description
Product Overview
The Schaffner IT series pulse transformers provide galvanic separation between drive and power circuits, offering voltage resistance up to 8 kV and ignition currents up to 3 A. Designed for transformer-coupled gate drives, they feature negligible delays, voltage scaling capabilities, and are available with single or double secondary windings. These transformers ensure rapid availability of standard gate drive solutions with a wide selection of turns ratios, ignition currents, and voltages.

Notes:
- * Tolerance: +50%; -30% for Inductance (Lp).
- ** IT 364 is not suitable for PCB-mounting.
- tr: rise time at given load resistor R and 70% of the output pulse height.
- Lp: primary inductance measured at 1 kHz (secondary coile open).
- Lstr: stray inductance measured at the secondary side, short circuit at the primary side. If there are several secondary coils only one at the time is connected (measuring frequency 10 kHz).
- The ignition current is a set peak value where the voltage drop over the coil resistance is still insignificant (mostly below 1 V).
General Technical Data:
- Nominal operating voltage: Up to 3000 V
- Operating frequency: 40 kHz max. / 500 kHz max. for data transmission
- DC to 40000 Hz
- Voltage resistance: Up to 8 kV
- Test voltage: Up/50 Hz/2 s max. according to VDE 110b
- Max. partial discharge voltage: 1.5 x Unom
- Temperature range (operation and storage): -25C to +70C (25/70/21)
- Flammability: corresponding to UL 94 V-0 listed materials
Typical Applications:
- Gate drive circuit
- Power supplies
- Power converters
- Frequency converters
- Switching applications
- DC/DC converters
- Line coupling transformers in high-speed data transmission
