The WA8427-AED is a low-profile, center-tapped push-pull isolation transformer designed for use with the Texas Instruments SN6505B push-pull driver, operating at 400 kHz with a 2.25-5.5 V input. It provides a 5.0 V output with a 1:1.11 turns ratio, 145 µH primary inductance, and 2500 Vrms one-minute isolation between windings. The part is AEC-Q200 qualified, RoHS compliant, and halogen-free, with a maximum operating temperature of +165°C and a weight of 0.60-0.65 g. It is supplied in tape and reel packaging, 900 per 13" reel, with 24 mm wide plastic tape and 16 mm pocket spacing. Ambient temperature range is -40°C to +125°C.
Coilcraft's ZA9709 and WA8427 miniature, low-profile transformer is designed for use with SN6505B transformer drivers from Texas Instruments. The center-tapped push-pull transformer features high isolation voltage and high efficiency for isolated power supplies. It is driven by the SN6505B from a 3.3 V power supply and provides high isolation at 2500 Vrms across the isolation barrier for interfaces such as CAN, RS-485, RS-422, RS-232, SPI, I2C , and low-power LAN in industrial and automotive applications. The ZA9709 and WA8427 are AEC Grade 1 qualified, making it an ideal solution for DC-DC converters in EV/HEV applications.
