Product details
Overview
TLP5751(D4-LF4,E) from Toshiba Electronic Devices & Storage Corporation is a reinforced-insulation photocoupler with integrated high-speed photodetector and totem-pole output stage, designed for gate driving IGBTs and MOSFETs in high-noise industrial inverters. It delivers ±1.0 A peak output current, 150 ns max propagation delay, ±35 kV/µs common-mode transient immunity, and operates from 15–30 V supply across –40°C to +110°C - enabling compact, safety-certified isolation in induction cooktops and air conditioner inverters.
For engineers reviewing the TLP5751(D4-LF4,E) datasheet, TLP5751(D4-LF4,E) pinout, TLP5751(D4-LF4,E) application, or TLP5751(D4-LF4,E) equivalent, key selection criteria include its VDE-approved EN IEC 60747-5-5 compliance (D4 option), rail-to-rail output capability, 5000 Vrms isolation voltage, and SO6L package with LF4 lead forming - all critical for high-reliability gate drive isolation in safety-critical power conversion systems.
Technical Context
The TLP5751(D4-LF4,E) integrates an infrared LED coupled to a high-gain, high-speed photo IC with internal Faraday shield, delivering guaranteed ±35 kV/µs CMTI. Its totem-pole (buffer logic) output supports rail-to-rail switching between VCC and GND, eliminating external pull-up resistors and enabling direct connection to power device gates.
This variant implements the D4 option per EN IEC 60747-5-5 for reinforced insulation, verified under VDE approval, and uses LF4 lead forming for wide-lead spacing - both essential for meeting creepage/clearance requirements (≥8.0 mm) and long-term reliability in high-voltage motor drives and home appliance inverters.
Key Specifications

Pinout & Package
Package: SO6L (TOSHIBA designation 11-4N101A), surface-mount, 6-pin, wide-lead-forming (LF4) variant with 8.0 mm minimum creepage and clearance distances.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode input - requires series resistor to limit IF to 6–15 mA per recommended operating conditions. |
| 2 | N.C. | No internal connection - must remain unconnected; no routing or copper pour allowed. |
| 3 | Cathode | LED cathode return - connects to system ground or controller low-side switch node. |
| 4 | GND | Photodetector ground reference - must be tied to local gate driver ground with minimal impedance. |
| 5 | VO (Output) | Rail-to-rail totem-pole output - sinks or sources up to ±1.0 A to drive gate capacitance directly. |
| 6 | VCC | Positive supply input - requires 1 µF ceramic bypass capacitor placed ≤1 cm from pins 4 and 6 per datasheet requirement. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Insulation (D4) | EN IEC 60747-5-5 certified - enables single-component isolation barrier meeting IEC 61800-5-1 for functional safety in variable-frequency drives. |
| Rail-to-Rail Output | Eliminates need for external pull-up resistors - reduces component count and improves rise/fall time consistency in gate drive paths. |
| Internal Faraday Shield | Guarantees ±35 kV/µs CMTI - prevents noise-induced misfiring in high-dv/dt environments like IGBT half-bridges. |
| Buffer Logic Type | Totem-pole configuration - provides symmetrical sourcing/sinking capability ideal for driving both N-channel and P-channel gate drivers. |
| UVLO Protection | Integrated undervoltage lockout with 12.1–13.5 V threshold - disables output if VCC drops below safe gate-drive level, preventing partial turn-on of power devices. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar gate driver isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP5752(D4-LF4,E) | Dual-channel version in same SO6L package; shares identical specs per channel but doubles channel count. | Suitable for half-bridge or dual-MOSFET topologies requiring two isolated gate drivers on one IC. | Select when board space constraints favor integration over discrete single-channel units. |
| ACPL-332J-000E | Lower CMTI (±25 kV/µs), 2.5 kVrms isolation, different SO-6 footprint (Avago/Broadcom), no D4 certification. | Limited to basic insulation applications; not approved for reinforced insulation per EN IEC 60747-5-5. | Acceptable only where safety standards permit basic insulation and lower noise immunity suffices. |
Compared with TLP5751(D4-LF4,E), the TLP5752(D4-LF4,E) offers channel doubling without sacrificing D4 compliance or CMTI, while the ACPL-332J-000E trades safety certification and noise immunity for broader distributor availability - making TLP5751(D4-LF4,E) the optimal choice for VDE-mandated, high-CMTI gate drive isolation.

FAQ
What safety certifications apply to the TLP5751(D4-LF4,E)?
The TLP5751(D4-LF4,E) carries VDE approval per EN IEC 60747-5-5 (reinforced insulation), UL 1577 recognition (File No. E67349), cUL CSA Component Acceptance (File No. E67349), and CQC GB4943.1 certification. The "D4" suffix explicitly denotes compliance with the EN IEC 60747-5-5 option, validated through third-party testing - critical for meeting IEC 61800-5-1 in industrial drives. TLP5751(D4-LF4,E) documentation includes full test reports and certificate numbers traceable to Toshiba's official VDE file.
Why does the TLP5751(D4-LF4,E) require a 1 µF capacitor between pins 6 and 4?
A 1 µF ceramic capacitor is mandatory between VCC (pin 6) and GND (pin 4) to stabilize the internal high-gain photodetector amplifier and prevent oscillation or erratic switching. Per Toshiba's datasheet (Section 6 and Note in Section 9), placement must be within 1 cm of the pins; failure to install it causes improper output transitions, especially under high CMTI stress. This requirement applies uniquely to TLP5751(D4-LF4,E) due to its integrated Faraday shield and rail-to-rail architecture - not optional or design-dependent.
Can the TLP5751(D4-LF4,E) drive both IGBTs and MOSFETs directly?
Yes - the TLP5751(D4-LF4,E) delivers ±1.0 A peak output current and rail-to-rail VO swing (0 V to VCC), enabling direct gate drive of medium-power IGBTs (up to 600 V/50 A) and N-channel MOSFETs (up to 650 V) without external buffers. Its 150 ns max propagation delay and ±35 kV/µs CMTI ensure reliable switching in hard-switched topologies. TLP5751(D4-LF4,E)'s totem-pole output eliminates shoot-through risk in half-bridge configurations when paired with complementary gate control logic.
What is the significance of the "LF4" lead forming option in TLP5751(D4-LF4,E)?
The "LF4" designation specifies wide-lead forming per Toshiba's 11-4N101A package drawing, increasing creepage and clearance distances to ≥8.0 mm - a mandatory requirement for reinforced insulation under EN IEC 60747-5-5 and UL 1577. Unlike standard SO6L variants, TLP5751(D4-LF4,E)'s LF4 leads prevent arcing across PCB surfaces in high-humidity or pollution-degree-3 environments typical of industrial inverters and kitchen appliances.
How does the TLP5751(D4-LF4,E) handle undervoltage conditions?
The TLP5751(D4-LF4,E) incorporates integrated undervoltage lockout (UVLO) with a 12.1–13.5 V activation threshold. When VCC drops below this range, the output is forced low to prevent partial turn-on of power devices - a critical fail-safe in brownout conditions. UVLO hysteresis (≥0.5 V) avoids chatter near the threshold. This behavior is specified in Section 10 of the datasheet and applies identically across all TLP5751(D4-LF4,E) units, independent of temperature or load.
