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.

Technical Specifications

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).
