Toshiba Semiconductor and Storage TLP5751(TP,E

Overview

TLP5751(TP,E) from Toshiba Electronic Devices & Storage Corporation is a high-speed, rail-to-rail output photocoupler with integrated photodetector and infrared LED in a 6-pin SO6L package. It delivers ±1.0 A peak output current, 150 ns max propagation delay, and ±35 kV/µs common-mode transient immunity, enabling robust gate driving for IGBTs and MOSFETs in induction cooktops and industrial inverters.

For engineers reviewing the TLP5751(TP,E) datasheet, TLP5751(TP,E) pinout, TLP5751(TP,E) application, or TLP5751(TP,E) equivalent, key selection criteria include reinforced insulation (5000 Vrms), totem-pole buffer logic, UVLO protection, and compatibility with 15–30 V supply rails in high-noise motor control environments.

Technical Context

The TLP5751(TP,E) integrates an infrared LED coupled to a high-gain, high-speed photo IC with internal Faraday shielding-ensuring ±35 kV/µs CMTI and stable switching under fast dv/dt transients. Its totem-pole output stage supports rail-to-rail voltage swing (VOH ≥ 14.7 V, VOL ≤ 0.2 V at VCC = 30 V), eliminating external pull-up/pull-down components.

It operates across –40 °C to +110 °C with UVLO thresholds at 12.1 V (rising) and 11.1 V (falling), and requires a mandatory 1 µF ceramic bypass capacitor between VCC (Pin 6) and GND (Pin 4) within 1 cm for stable high-gain amplifier operation.

FAQ

What is the maximum recommended operating temperature for the TLP5751(TP,E)?

The TLP5751(TP,E) is rated for continuous operation from –40 °C to +110 °C. This range is validated per its absolute maximum ratings and electrical characteristics tables, supporting use in sealed induction cooktop enclosures and outdoor-rated HVAC inverters without thermal derating. The device maintains specified propagation delay, output current, and CMTI performance across this full range, as confirmed in Section 12 of the Toshiba datasheet Rev.11.0.

Does the TLP5751(TP,E) require an external bypass capacitor, and if so, what value and placement?

Yes-the TLP5751(TP,E) requires a 1 µF ceramic capacitor connected between Pin 6 (VCC) and Pin 4 (GND). Per Section 6 and Note in Section 9 of the datasheet, this capacitor must be placed within 1 cm of those pins to stabilize the internal high-gain amplifier and prevent improper switching. Failure to install it may cause erratic output behavior or latch-up under load.

What safety certifications does the TLP5751(TP,E) hold, and are they applicable to the exact part number?

The TLP5751(TP,E) is UL-recognized (UL 1577, File No. E67349), cUL-recognized (CSA 5A File No. E67349), VDE-approved (EN IEC 60747-5-5 and EN IEC 62368-1), and CQC-approved (GB4943.1). These certifications apply to the base TLP5751 family; the (TP,E) variant uses the same die and SO6L package as the certified type, and Toshiba confirms equivalency in Section 17 of the datasheet.

Can the TLP5751(TP,E) drive both IGBTs and MOSFETs directly, and what is the peak output capability?

Yes-the TLP5751(TP,E) provides ±1.0 A peak output current (Section 3, Feature #2), sufficient to directly drive the gate of medium-power IGBTs (e.g., 50 A/600 V) and N-channel MOSFETs (e.g., 100 A/100 V) without external buffers. Its rail-to-rail output ensures full VCC-level gate voltage swing, minimizing conduction losses and improving switching efficiency in inverter half-bridges.

What is the function of Pin 2 (N.C.) on the TLP5751(TP,E), and how should it be handled on the PCB?

Pin 2 is a no-connect terminal-internally unconnected and electrically isolated from all other circuitry. Per Section 5 (Pin Assignment) of the datasheet, it must remain floating: no PCB trace, solder mask opening, or copper pour should contact it. Leaving it unconnected avoids parasitic coupling and ensures compliance with the device's certified creepage and clearance distances.
