Product details
Overview
TLP5751H(LF4,E) from Toshiba Electronic Devices & Storage Corporation is a 6-pin SO6L photovoltaic gate driver optocoupler integrating an infrared LED and high-speed photo IC for isolated MOSFET/IGBT switching. It delivers ±1.0 A peak output current, 150 ns max propagation delay, ±35 kV/µs common-mode transient immunity, and operates from -40 °C to +125 °C - enabling robust gate driving in industrial inverters and induction cooktops.
For engineers reviewing the TLP5751H(LF4,E) datasheet, TLP5751H(LF4,E) pinout, TLP5751H(LF4,E) application, or TLP5751H(LF4,E) equivalent, this page provides verified specifications, package details, real-world use cases, and validated alternative options for high-reliability isolated gate drive design.
Technical Context
The TLP5751H(LF4,E) implements a totem-pole buffer output stage with rail-to-rail voltage swing, enabling direct connection to power device gates without external level-shifting. Its internal Faraday shield ensures guaranteed ±35 kV/µs CMTI performance across temperature.
It features integrated UVLO (12.1 V turn-on / 11.1 V turn-off) and requires a 1 µF ceramic bypass capacitor between VCC (Pin 6) and GND (Pin 4) within 1 cm for stable high-gain amplifier operation. Input threshold is ≤4 mA, supporting low-power controller interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Propagation Delay | 150 ns max - enables >50 kHz switching in inverter applications with tight timing control |
| CMTI | ±35 kV/µs min - maintains signal integrity in noisy high-dV/dt motor drive environments |
| Isolation Voltage | 5000 Vrms min - meets reinforced insulation requirements per UL 1577, EN IEC 60747-5-5 |
| Operating Temp | -40 °C to +125 °C - supports under-hood and industrial ambient conditions without derating |
| Supply Voltage | 15–30 V - compatible with standard 24 V industrial rails and wide-range auxiliary supplies |
| Input Threshold | ≤4 mA - interfaces directly with microcontroller GPIOs or low-current logic outputs |
Pinout & Package
Package: 6-pin SO6L (Toshiba package code 11-4N101A), surface-mount, lead-forming option LF4, creepage/clearance ≥8.0 mm, isolation thickness ≥0.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: Anode | LED input anode | Connects to current-limited logic/high-side driver; requires series resistor for IF = 6–11 mA |
| 2: N.C. | No connect | Internally unconnected; must remain floating - no PCB trace or solder mask bridge |
| 3: Cathode | LED input cathode | Reference return for LED forward current; ties to controller ground or low-side switch |
| 4: GND | Detector ground | Return path for output stage and bypass capacitor; must be low-inductance local ground plane |
| 5: VO (Output) | Buffer output | Rail-to-rail totem-pole source/sink - directly drives gate of N-channel MOSFET or IGBT |
| 6: VCC | Detector supply | Power input for photo IC; requires 1 µF ceramic cap to Pin 4 within 1 cm for stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail totem-pole output | Enables full-swing gate drive without external level shifters or pull-up resistors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP5751(TP4,E) | Same die, tape-and-reel packaging (TP4) instead of magazine (LF4); identical electrical specs and SO6L footprint | No change in circuit design or layout - only differs in delivery format and reel quantity (1500 pcs vs 125 pcs) | Select TLP5751(TP4,E) for automated SMT production requiring tape feed; TLP5751H(LF4,E) suits prototyping and low-volume assembly |
| ACPL-332J-500E | Lower peak output (±0.6 A), higher propagation delay (200 ns max), same 5000 Vrms isolation and SO6 package | Suitable for lower-power MOSFETs but not recommended for high-Ciss IGBTs requiring >0.8 A gate current | Choose ACPL-332J-500E only when gate charge demand is ≤0.6 A and timing budget allows >50 ns extra delay |
Compared with TLP5751H(LF4,E), TLP5751(TP4,E) offers identical performance in tape-and-reel form for volume manufacturing, while ACPL-332J-500E trades peak current and speed for broader distributor availability - making it viable only in lower-power, less timing-critical gate drive roles.

FAQ
What is the maximum operating temperature for the TLP5751H(LF4,E)?
The TLP5751H(LF4,E) is rated for continuous operation from -40 °C to +125 °C. This extended range is validated per its absolute maximum ratings and electrical characteristics tables, enabling deployment in under-hood automotive subsystems and industrial motor drives where ambient temperatures exceed 100 °C. The TLP5751H(LF4,E) maintains guaranteed propagation delay and output current performance across this full range.
Does the TLP5751H(LF4,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 device. This is mandatory per Toshiba's recommended operating conditions to stabilize the high-gain linear amplifier inside the TLP5751H(LF4,E) and prevent oscillation or improper switching. Omitting or misplacing this capacitor risks unreliable output behavior in the TLP5751H(LF4,E).
What safety certifications does the TLP5751H(LF4,E) hold?
The TLP5751H(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, including 5000 Vrms isolation voltage and ≥8.0 mm creepage/clearance - all verified for the exact TLP5751H(LF4,E) variant.
Can the TLP5751H(LF4,E) drive IGBTs directly without external components?
Yes - the TLP5751H(LF4,E) delivers ±1.0 A peak output current and rail-to-rail voltage swing, allowing direct gate drive of medium-power IGBTs (e.g., up to 50 A/600 V) without external MOSFET buffers or level shifters. Its totem-pole output stage and UVLO protection make the TLP5751H(LF4,E) a self-contained gate driver solution for discrete power devices.
What is the purpose of Pin 2 (N.C.) on the TLP5751H(LF4,E)?
Pin 2 on the TLP5751H(LF4,E) is a no-connect terminal - internally unconnected and electrically isolated. It must remain unconnected on the PCB: no trace, no pad tie, no solder mask opening. This mechanical pin exists for package symmetry and handling; routing to ground or any net violates the TLP5751H(LF4,E)'s isolation barrier and may compromise safety certification.
