The H-grade versions operate up to a junction temperature of 150°C, compared to the E- and I-grade versions’ 125°C maximum junction temperature. All electrical specifications are identical for the E, I and H. The H-grade parts are tested and guaranteed to the maximum junction temperature of 150°C, and are ideal for automotive and industrial applications which are subject to high ambient temperatures.
The LT3692AHUH is packaged in a 32-lead 5mm x 5mm QFN, priced starting at $4.95 each for 1,000 piece quantities. LT3692AHFE is packaged in a thermally enhanced TSSOP-38 and is FMEA compliant, pricing starts at $5.37 each for 1,000 piece quantities. Both versions are available from stock.
