Toshiba Semiconductor and Storage TLP5751H(TP4,E

Overview

TLP5751H(TP4,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 ±4.0 A peak output current, 150 ns max propagation delay, ±35 kV/µs common-mode transient immunity, and 5000 Vrms isolation voltage for IGBT/MOSFET gate driving in industrial inverters and home appliance inverters.

For engineers reviewing the TLP5751H(TP4,E) datasheet, TLP5751H(TP4,E) pinout, TLP5751H(TP4,E) application, or TLP5751H(TP4,E) equivalent, key selection criteria include guaranteed operation at 125°C, totem-pole buffer logic output, UVLO protection, and reinforced insulation compliance per EN IEC 60747-5-5 and UL 1577.

Technical Context

The TLP5751H(TP4,E) integrates an infrared LED coupled to a high-gain, high-speed photodetector with internal Faraday shield, enabling robust noise immunity in high-dv/dt environments. Its totem-pole output stage supports rail-to-rail switching across 15–30 V supply range and delivers symmetrical ±4.0 A peak current into capacitive loads.

It features under-voltage lockout (UVLO) with 12.1 V turn-on and 11.1 V turn-off thresholds, ensuring safe gate drive during brown-out conditions. The device operates over –40°C to +125°C and meets reinforced insulation requirements with 8.0 mm creepage/clearance and 0.4 mm minimum insulation thickness.

Equivalent & Alternatives

The following parts are listed as comparable options for similar photocoupler gate driver applications.

Compared with TLP5754H(TP4,E), the TLP5751H(TP4,E) provides identical pinout, timing, and drive strength but omits the D4 certification suffix - making it ideal for cost-sensitive industrial designs where UL/CSA compliance suffices. Against ACPL-332J-500E, TLP5751H(TP4,E) delivers 60% higher peak current and superior noise immunity, justifying its use in high-reliability inverter gate drive.

FAQ

What is the maximum operating temperature for the TLP5751H(TP4,E)?

The TLP5751H(TP4,E) is rated for continuous operation from –40°C to +125°C ambient temperature. This specification is validated per Toshiba's absolute maximum ratings and electrical characteristics tables, enabling use in sealed inverter modules and outdoor-rated HVAC equipment without thermal derating of output current or timing parameters.

Does the TLP5751H(TP4,E) require an external bypass capacitor?

Yes, a 1 µF ceramic capacitor must be placed between pin 6 (VCC) and pin 4 (GND) within 1 cm of the pins. This is explicitly required in Toshiba's recommended operating conditions to stabilize the high-gain linear amplifier stage and prevent oscillation or improper switching behavior in the TLP5751H(TP4,E).

What safety standards does the TLP5751H(TP4,E) comply with?

The TLP5751H(TP4,E) is UL-recognized (UL 1577, File No. E67349), cUL-recognized (CSA Component Acceptance Service No. 5A, File No. E67349), and compliant with EN IEC 62368-1. While not pre-certified to EN IEC 60747-5-5, its construction meets the insulation requirements - D4-option variants (e.g., TLP5754H(D4TP4,E)) provide formal VDE approval.

Can the TLP5751H(TP4,E) drive both IGBTs and MOSFETs?

Yes, the TLP5751H(TP4,E) delivers ±4.0 A peak output current with rail-to-rail voltage swing, making it suitable for driving the gates of both high-voltage IGBTs and low-threshold MOSFETs. Its 150 ns max propagation delay and ±35 kV/µs CM immunity ensure clean, synchronized switching in half-bridge and three-phase inverter configurations.

What is the purpose of pin 2 on the TLP5751H(TP4,E)?

Pin 2 on the TLP5751H(TP4,E) is designated N.C. (No Connection) and has no internal bond or electrical function. It must remain unconnected in PCB layout and schematic design - bridging or routing to this pin may compromise isolation integrity or cause unpredictable behavior in the TLP5751H(TP4,E).
