Product details

Package and mounting

Housed in a 20-TSSOP package with an exposed pad (0.173" body width, 4.40 mm width, 16 leads plus pad), the LT8311EFE#PBF is a surface-mount device. The exposed pad must be soldered to a thermal land on the PCB for heat dissipation — a common requirement for drivers that handle gate charge at high frequency. The supplier device package is designated 20-TSSOP-EP.

Lifecycle and compliance

The LT8311EFE#PBF is listed as Active on the manufacturer's lifecycle status, with no end-of-life notification or last-time-buy window. It is ROHS3 compliant. For new designs or production replenishment, this part is available through independent distribution and is sourced to order against an RFQ — no LTB risk, no forced redesign.

Frequently asked questions

What is the LT8311EFE#PBF used for?

It is a synchronous MOSFET driver for secondary-side controller applications in isolated power converters — typically used in flyback or forward topologies to drive an external N-channel MOSFET for synchronous rectification, improving efficiency.

Does LT8311EFE#PBF have a direct replacement or equivalent part?

The LT8311HFE#PBF is a functional peer with the same package, mounting, application type, supply voltage, and supply current, but with the same -40°C to 150°C temperature range. The LT8311MPFE#PBF extends the temperature range to -55°C to 150°C. Neither is a drop-in replacement without verifying the temperature grade needed for your application.
