The PS9309L2-V-E3-AX: The Renesas PS9309L2-V--AX is a single-channel optoisolated gate driver with a push-pull totem-pole output, rated for 5000Vrms of galvanic isolation. The 6-SDIP Gull Wing package (6.80mm body width) provides more pin-to-pin creepage than a standard SOIC-8, which helps maintain the 5000Vrms rating across the PCB layout without relying on slots or heavy conformal coat.
1Mbps data rate and 200ns propagation delay — where the speed lands
The 1Mbps data rate and 200ns max propagation delay (tpLH / tpHL) position this part for moderate-speed isolation: think IGBT gate drive at switching frequencies up to a few tens of kHz, or isolated digital inputs for 24V PLC fieldbuses. It will not keep up with high-speed encoder interfaces or 10Mbps+ industrial Ethernet isolation — for those, look at the 15Mbps peers in the same package footprint. The 24ns typical rise time versus 3.2ns fall time asymmetry means the output edges are not symmetrical; the push-pull stage pulls low much faster than it pulls high. In a gate-drive application, factor this into the turn-off timing budget.
The output-side supply range of 4.5V to 20V covers standard 5V and 15V gate-drive rails, and the 25mA per-channel output current is enough to drive the gate of a medium-power IGBT or MOSFET directly for low-frequency switching. For higher gate charge devices, plan on a buffer stage. Input-side drive requires a forward voltage of 1.55V typical at up to 20mA forward current — compatible with 3.3V or 5V logic outputs through a series resistor.
Temperature range and environment
The 110°C ceiling is 25°C above standard commercial parts, giving headroom in a warm enclosure.
