Product details

Why the 4A peak output matters for your power stage

The TLP5774(TP,E delivers a 4A peak output current — enough to drive medium-power IGBTs and SiC MOSFETs directly, without an external buffer stage. That saves board space and BOM cost in motor drives, UPS, and industrial power supplies. With 35kV/µs common-mode transient immunity, the part rejects fast dV/dt noise from the switching node — a common failure mode in inverter designs where the floating gate-drive signal can be corrupted by the half-bridge slew. The 5000Vrms isolation rating supports reinforced insulation per IEC 60747-5-5, qualifying it for mains-isolated gate-drive circuits in equipment rated up to 600V bus.

Switching speed and timing margin

Rise and fall times of 15ns and 8ns typical keep switching losses low at 100 kHz+ hard-switched frequencies. Maximum propagation delay is 150ns for both tpLH and tpHL, with pulse-width distortion capped at 50ns — tight enough for interleaved or phase-shifted topologies where timing skew between channels must stay under a few percent of the switching period. Compared to the TLP5752(D4-TP,E (2.5A peak), the TLP5774(TP,E adds 1.5A of peak drive current — the extra margin lets you drive larger IGBT modules or reduce gate-resistor power dissipation by switching faster.

Sourced to order against your BOM line.

Package and mounting for the rework bench

6-SOIC package (0.295", 7.50mm width) with a 1.27mm pitch — standard SOIC-6 footprint. The 6-SO supplier device package is the same body as a standard SO-8 but with only 6 leads, so the PCB footprint matches a common SOIC-8 land pattern with the two centre pads omitted. Surface-mount mounting with a typical MSL of 1 (no moisture bake needed unless the reel has been exposed beyond the floor life). The 110°C operating maximum allows placement near the heatsink in enclosed power supplies without derating.

Frequently asked questions

Can TLP5774(TP,E drive IGBTs with 4A peak?

Yes, the 4A peak output is specified for driving IGBTs and power MOSFETs. The 15ns rise / 8ns fall times and 150ns max propagation delay are well suited for switching frequencies up to 150 kHz with typical gate charges under 1 µC.

What is the closest functional second-source to TLP5774(TP,E?

Within the Toshiba family, the TLP5774(D4,E shares the same 4A peak output, 5000Vrms isolation, 35kV/µs CMTI, and 6-SOIC package — the difference is tube packaging vs tape & reel. The TLP5752(D4-TP,E is a 2.5A peak alternative with the same isolation and speed, suitable for lower gate-charge loads.
