Product details
Overview
TLP5751(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 ±1.0 A peak output current, 150 ns max propagation delay, ±35 kV/µs common-mode transient immunity, and 5000 Vrms isolation voltage-designed for driving IGBTs and MOSFETs in industrial inverters and induction cooktops.
For engineers reviewing the TLP5751(TP4,E) datasheet, TLP5751(TP4,E) pinout, TLP5751(TP4,E) application, or TLP5751(TP4,E) equivalent, key selection criteria include reinforced insulation compliance (UL/cUL/VDE), totem-pole buffer logic, UVLO protection, and 15–30 V supply range suitable for high-noise motor control environments.
Technical Context
The TLP5751(TP4,E) integrates an infrared LED coupled to a high-gain, high-speed photodetector with internal Faraday shield-enabling guaranteed ±35 kV/µs CMTI and reinforced insulation per EN IEC 60747-5-5. Its totem-pole output stage provides rail-to-rail switching with fast rise/fall times under 50 ns at 30 V supply.
Operation requires a 1 µF ceramic bypass capacitor between VCC (Pin 6) and GND (Pin 4), and it features built-in undervoltage lockout (UVLO) with 12.1–13.5 V activation threshold and 0.7 V hysteresis-ensuring robust gate drive during brown-out conditions in inverter power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms min - meets reinforced insulation requirements for industrial safety certification (UL 1577, EN IEC 60747-5-5). |
| Output Peak Current | ±1.0 A max - sufficient to directly drive medium-power IGBTs/MOSFETs without external buffers. |
| Propagation Delay | 150 ns max - enables reliable operation up to 50 kHz switching frequency in inverter gate drive circuits. |
| CMTI | ±35 kV/µs min - suppresses false triggering in high-dV/dt motor drive environments. |
| Supply Voltage Range | 15–30 V - compatible with standard industrial gate driver supply rails and supports UVLO functionality. |
| Operating Temperature | −40 to +110 °C - qualified for under-hood and enclosed inverter applications without derating. |
| Threshold Input Current | 4 mA max - ensures low-power LED drive compatibility with microcontroller GPIO or logic-level signal sources. |
Pinout & Package
Package: 6-pin SO6L (TOSHIBA package code 11-4N1A), surface-mount, creepage/clearance ≥8.0 mm, height ≤2.3 mm, weight 0.126 g (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: Anode | LED input anode | Connects to current-limited logic/high-side driver; requires series resistor for IF = 6–15 mA operation. |
| 2: N.C. | No connection | Internally unconnected; must remain floating-no routing or soldering required. |
| 3: Cathode | LED input cathode | Return path for LED forward current; ties to ground or low-side switch in driving circuit. |
| 4: GND | Detector ground reference | System ground for output stage; mandatory connection point for 1 µF bypass capacitor. |
| 5: VO (Output) | Buffered output terminal | Rail-to-rail totem-pole output driving gate of power device; sinks/sourcing capability up to ±1.0 A. |
| 6: VCC | Detector supply rail | Positive supply for photodetector IC; must be decoupled to Pin 4 with 1 µF ceramic capacitor within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail totem-pole output | Enables full-swing gate drive (0 V to VCC) without external level-shifting or pull-up resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photocoupler gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ACPL-332J-500E | SO-6 package, ±0.6 A output, 200 ns max tpHL/tpLH, 3750 Vrms isolation, no integrated UVLO. | Lacks UVLO and lower peak current; suited for lower-power MOSFETs where system-level brown-out protection exists. | Select when cost sensitivity outweighs need for integrated UVLO and higher drive strength. |
| SI8261BBC-C-ISR | SiO₂-based digital isolator, 4 A peak output, 40 ns propagation delay, 5 kVrms isolation, 3.3/5 V logic-compatible inputs. | Requires external gate resistor and level-shifter; superior speed but lacks integrated LED driver and analog input interface. | Choose for ultra-fast timing-critical designs where discrete LED driver and logic-level input are acceptable. |
Compared with ACPL-332J-500E and SI8261BBC-C-ISR, the TLP5751(TP4,E) uniquely combines integrated LED driver, rail-to-rail totem-pole output, UVLO, and reinforced insulation in one SO6L package-reducing BOM count and layout complexity for industrial inverter gate drive.

FAQ
What is the recommended bypass capacitor for TLP5751(TP4,E) and where should it be placed?
A 1 µF ceramic capacitor must be connected between Pin 6 (VCC) and Pin 4 (GND) of the TLP5751(TP4,E) to stabilize the high-gain photodetector amplifier. This capacitor must be placed within 1 cm of those pins to prevent oscillation and ensure reliable rail-to-rail switching performance across the full −40 to +110 °C operating range.
Does TLP5751(TP4,E) support direct drive of 600 V IGBTs without external components?
Yes-the TLP5751(TP4,E) delivers ±1.0 A peak output current and rail-to-rail voltage swing, enabling direct gate drive of medium-power 600 V IGBTs (e.g., 50 A rated) in hard-switched inverters. No external push-pull buffer is required, though gate resistor selection remains critical for optimizing dV/dt and EMI.
What safety certifications apply to TLP5751(TP4,E)?
The TLP5751(TP4,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 confirm its suitability for reinforced insulation in Class I and II equipment.
How does the UVLO function in TLP5751(TP4,E) protect power devices?
The TLP5751(TP4,E) incorporates undervoltage lockout that disables the output when VCC drops below 12.1–13.5 V (with 0.7 V hysteresis). This prevents partial turn-on of IGBTs/MOSFETs during supply brown-out-eliminating shoot-through risk and thermal stress in the TLP5751(TP4,E)-driven power stage.
Can TLP5751(TP4,E) replace older DIP-8 photocouplers without PCB redesign?
No-TLP5751(TP4,E) uses a 6-pin SO6L package (11-4N1A), not pin-compatible with legacy 8-pin DIP packages. While it offers 50 % smaller footprint and improved specs, migration requires PCB layout revision to accommodate the SO6L land pattern and updated bypass capacitor placement per datasheet Fig. 15.1.
