Product details
Overview
TLP5702H(LF4,E) from Toshiba Electronic Devices & Storage Corporation is a 6-pin SO6L photocoupler integrating an infrared LED and high-speed photodetector IC, delivering ±2.5 A peak output current, 200 ns max propagation delay, ±50 kV/µs common-mode transient immunity, and 5000 Vrms isolation voltage for IGBT/MOSFET gate drive in industrial inverters and PV power conditioning systems.
For engineers reviewing the TLP5702H(LF4,E) datasheet, TLP5702H(LF4,E) pinout, TLP5702H(LF4,E) application, or TLP5702H(LF4,E) equivalent, this device supports safety-certified, space-constrained designs requiring reinforced insulation, fast switching, and robust noise immunity in high-voltage motor control and appliance inverter circuits.
Technical Context
The TLP5702H(LF4,E) implements a totem-pole buffer output stage with UVLO protection, enabling direct gate driving of power semiconductors without external level-shifting circuitry. Its internal noise shield and dual-stage photodetector architecture ensure stable operation under rapid dV/dt transients up to ±50 kV/µs.
It operates across -40°C to +125°C with 15–30 V supply voltage, 5 mA max threshold input current, and requires a mandatory 0.1 µF bypass capacitor between VCC (Pin 6) and GND (Pin 4) to stabilize the high-gain amplifier core and prevent oscillation during high-speed switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms min - enables reinforced insulation compliance per UL 1577, EN IEC 60747-5-5, and GB4943.1. |
| Output Peak Current | ±2.5 A max - drives medium-power IGBTs and MOSFETs directly without external buffers. |
| Propagation Delay | tpHL/tpLH ≤ 200 ns - supports PWM frequencies up to 50 kHz with tight timing control. |
| Common-Mode Immunity | ±50 kV/µs min - suppresses noise coupling in high-dV/dt inverter half-bridges and PV string interfaces. |
| Supply Voltage Range | 15–30 V - compatible with standard industrial gate driver rails and provides margin for UVLO hysteresis. |
| Operating Temperature | -40°C to +125°C - rated for under-hood and enclosed inverter environments without derating. |
| Threshold Input Current | ≤ 5 mA - ensures reliable turn-on with low-power MCU GPIO or isolated logic outputs. |
Pinout & Package
Package: SO6L (Toshiba 11-4N101A), lead-formed (LF4), height ≤ 2.3 mm, 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 MCU or logic source; requires series resistor for IF = 6.5–10 mA. |
| 2: N.C. | No connection | Internally unconnected; must remain floating - no PCB trace or pad required. |
| 3: Cathode | LED input cathode | Return path for LED forward current; ties to system ground or logic low reference. |
| 4: GND | Detector ground | Reference for output stage and bypass capacitor; must be low-impedance local ground plane. |
| 5: VO | Output driver terminal | Delivers ±2.5 A to gate of IGBT/MOSFET; connects directly to gate resistor and device gate. |
| 6: VCC | Output stage supply | Provides power to photodetector IC; requires 0.1 µF ceramic capacitor to Pin 4 within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| Buffer logic output | Totem-pole configuration eliminates need for external pull-up/pull-down resistors in gate drive paths. |
| UVLO protection | Active below ~11 V (VUVLO−) with ~1.5 V hysteresis - prevents partial turn-on and shoot-through during brownout. |
| Reinforced insulation | 5000 Vrms isolation and 8.0 mm creepage meet IEC 62368-1 and EN 60747-5-5 for functional safety applications. |
| High-speed switching | 200 ns max propagation delay and <80 ns pulse width distortion enable precise PWM edge alignment. |
| ESD-hardened design | Enhanced layout and process reduce susceptibility to handling-induced ESD damage during assembly. |
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 |
|---|---|---|---|
| ACPL-332J-500E | SO-6 package, ±2.5 A output, but 350 ns max tpHL/tpLH and 35 kV/µs CMTI. | Limited to lower-frequency (<25 kHz) inverters where tighter timing and higher noise immunity are not required. | Choose when cost sensitivity outweighs need for sub-200 ns timing or >40 kV/µs CMTI in non-safety-critical systems. |
| SI8271BD-D-IS | Dual-channel, 4 A peak output, 100 ns max propagation delay, but requires external isolated supply and lacks integrated UVLO. | Suitable for dual-leg synchronous rectification or multi-phase motor control where channel count and speed are prioritized over integration. | Prefer when dual-output topology or faster switching justifies added BOM complexity and layout effort. |
Compared with ACPL-332J-500E and SI8271BD-D-IS, the TLP5702H(LF4,E) delivers superior CMTI and tighter propagation delay in a single-channel, fully integrated package with built-in UVLO - making it optimal for space-constrained, safety-certified single-leg IGBT/MOSFET gate drive in PV, HVAC, and appliance inverters.

FAQ
What is the recommended bypass capacitor for TLP5702H(LF4,E), and where must it be placed?
A 0.1 µF ceramic capacitor is mandatory between Pin 6 (VCC) and Pin 4 (GND) to stabilize the high-gain photodetector amplifier. It must be placed within 1 cm of those pins on the PCB to minimize loop inductance and prevent oscillation during fast switching events. Failure to install this capacitor may result in erratic output behavior or failure to switch reliably in the TLP5702H(LF4,E).
Does TLP5702H(LF4,E) support direct drive of SiC MOSFETs?
Yes, the TLP5702H(LF4,E) supports direct gate drive of discrete SiC MOSFETs with gate charge ≤ 50 nC at 15–30 V supply, thanks to its ±2.5 A peak output current and 200 ns propagation delay. However, gate resistor selection must account for SiC's lower input capacitance and faster dv/dt - typical Rg values range from 2.2 Ω to 10 Ω depending on switching loss vs. EMI trade-offs in the target application using the TLP5702H(LF4,E).
What safety certifications apply to TLP5702H(LF4,E)?
The TLP5702H(LF4,E) is UL-recognized (UL 1577, File No. E67349), cUL-recognized (CSA 5A File No. E67349), VDE-approved for EN IEC 60747-5-5 and EN IEC 62368-1 (when ordered with D4 option), and CQC-approved for GB4943.1. The base TLP5702H(LF4,E) meets all except VDE EN IEC 60747-5-5 unless specified with D4 suffix.
Can TLP5702H(LF4,E) operate without an external input current-limiting resistor?
No - TLP5702H(LF4,E) requires an external series resistor on the LED side (Pins 1–3) to limit forward current to 6.5–10 mA per recommended operating conditions. Without it, IF may exceed 20 mA absolute maximum rating, causing irreversible LED degradation. Resistor value is calculated as (VIO – VF)/IF, where VF ≈ 1.55 V and VIO is the driving source voltage.
What is the function of Pin 2 (N.C.) on TLP5702H(LF4,E), and how should it be handled on the PCB?
Pin 2 on the TLP5702H(LF4,E) is a no-connect terminal - internally unconnected and electrically isolated. It must remain unconnected on the PCB: no trace, no pad, and no solder mask opening required. Routing traces near or connecting to Pin 2 risks parasitic coupling or mechanical stress on the lead frame, potentially degrading isolation performance or reliability of the TLP5702H(LF4,E).
