The Toshiba TLP350H is a high-performance gate drive photocoupler designed to switch small- to medium-capacity IGBTs and power MOSFETs. It pairs a GaAlAs infrared LED with an integrated high-speed photodetector IC to deliver a peak output current of +/-2.5 A from a totem-pole output stage capable of both sourcing and sinking current. With 3750 Vrms isolation and an internal Faraday shield for strong common-mode noise rejection, the TLP350H is well suited to noisy industrial power-conversion environments.
Note: per Toshiba application guidance, a bypass ceramic capacitor should be connected close to the supply pins to stabilize the high-gain output stage and preserve switching performance.
The TLP350H can be difficult to obtain through authorized distribution channels in production quantities. Pacific Component Xchange is an independent distributor specializing in hard-to-find and allocated power-management ICs and optocouplers. We help engineers and buyers secure the TLP350H and equivalent Toshiba gate drive photocouplers even when stock is scarce or end-of-life sourcing support is required. Every part is sourced with authenticity verification and inspection, and we ship worldwide. Request a quote (RFQ) today and our sourcing team will respond with availability, pricing, lead time, and date-code options for your TLP350H requirement.
The TLP350H is a single-channel IGBT/MOSFET gate drive photocoupler from Toshiba. It combines a GaAlAs infrared LED with a high-speed photo-IC and totem-pole output stage to deliver a +/-2.5 A peak gate-drive current with 3750 Vrms isolation in a DIP8 package.
The TLP350H provides a peak output current of +/-2.5 A (max) from its totem-pole output, allowing it to both source and sink current to drive small- to medium-capacity IGBTs and power MOSFETs.
The TLP350H is rated for an isolation voltage (Viso) of 3750 Vrms minimum, and it includes an internal Faraday shield providing common-mode transient immunity of +/-20 kV/us minimum.
The recommended supply voltage range is 15 V to 30 V. A bypass capacitor placed close to the supply pins is recommended for stable operation, per Toshiba's application guidance.
The TLP350H is supplied in an 8-pin DIP (DIP8) package with 7.62 mm lead spacing. Orderable suffix variants include TLP350H(F) and TLP350H(TP1,F).
Yes. The TLP350H is offered on a request-for-quote (RFQ) basis. Because authorized-distributor stock can be limited, Pacific Component Xchange sources this hard-to-find Toshiba photocoupler with authenticity verification and global shipping.
