Toshiba Semiconductor and Storage TLP5754H(LF4,E

Overview

TLP5754H(LF4,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-designed for IGBT and MOSFET gate driving in industrial inverters and home appliance motor controls.

For engineers reviewing the TLP5754H(LF4,E) datasheet, TLP5754H(LF4,E) pinout, TLP5754H(LF4,E) application, or TLP5754H(LF4,E) equivalent, key selection criteria include guaranteed operation up to 125°C, reinforced insulation compliance (UL 1577, VDE EN IEC 60747-5-5), totem-pole buffer logic, and internal Faraday shield for noise-immune switching in high dv/dt environments.

Technical Context

The TLP5754H(LF4,E) integrates an infrared LED on the input side and a high-gain, high-speed photodetector with totem-pole output stage on the output side. Its internal Faraday shield ensures ±35 kV/µs CMTI, while rail-to-rail VO enables full-swing drive capability across 15–30 V supply range.

This device operates as a digital signal isolator with logic-level truth table (H/L input → H/L output), supports 50 kHz max switching frequency, and requires a 1 µF bypass capacitor between VCC (Pin 6) and GND (Pin 4) for stable high-gain amplifier operation-critical for reliable gate driving under fast transients.

FAQ

What is the maximum operating temperature for the TLP5754H(LF4,E)?

The TLP5754H(LF4,E) is rated for continuous operation from −40°C to +125°C ambient temperature. This specification is validated across all electrical parameters including propagation delay, output current, and CMTI performance. The device maintains guaranteed functionality at 125°C, making it suitable for enclosed industrial inverter modules and induction cooktop control boards where thermal management is constrained. Derating is not required within this range per Toshiba's Absolute Maximum Ratings table.

Does the TLP5754H(LF4,E) require an external bypass capacitor?

Yes-the TLP5754H(LF4,E) requires a 1 µF ceramic capacitor connected between Pin 6 (VCC) and Pin 4 (GND). Toshiba specifies this capacitor must be placed within 1 cm of both pins to stabilize the high-gain linear amplifier inside the photodetector. Omission or improper placement causes erratic switching behavior, increased propagation skew, or failure to achieve rail-to-rail output swing. This is not optional-it is a mandatory design requirement stated in Section 6 and Section 9 of the datasheet.

What safety certifications does the TLP5754H(LF4,E) hold?

The TLP5754H(LF4,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 confirm compliance with reinforced insulation requirements for end-equipment safety standards. Note: VDE approval applies only to versions designated with Option D4 (e.g., TLP5754H(D4TP4,E); the base TLP5754H(LF4,E) meets UL/cUL/CQC but requires D4 suffix for full VDE compliance.

Can the TLP5754H(LF4,E) drive both IGBTs and MOSFETs?

Yes-the TLP5754H(LF4,E) is explicitly qualified for both IGBT and MOSFET gate driving, as confirmed in Section 1 (Applications) and Section 2 (General) of the datasheet. Its ±4.0 A peak output current, rail-to-rail VO, and 15–30 V VCC range enable direct drive of low- to medium-power IGBTs (e.g., 600 V/50 A modules) and high-speed N-channel MOSFETs (e.g., 600 V/30 A). Toshiba validates performance under worst-case conditions including Ta = 125°C and exponential waveform loads per Section 8 Absolute Maximum Ratings.

What is the purpose of Pin 2 (N.C.) on the TLP5754H(LF4,E)?

Pin 2 on the TLP5754H(LF4,E) is a no-connect (N.C.) terminal-internally unconnected and electrically isolated from all other circuitry. It must remain floating: no PCB trace, solder mask opening, or via should contact Pin 2. This is specified in Section 5 (Pin Assignment) and reinforced in Section 8 (Absolute Maximum Ratings Note 4), which defines the device as a two-terminal system (Pins 1/2/3 shorted internally on input side; Pins 4/5/6 shorted on output side). Violating N.C. status risks compromising isolation integrity or causing parametric shift.
