Product details
Overview
TLP5751(D4-TP,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 across -40°C to +110°C in 6-pin SO6L package.
For engineers reviewing the TLP5751(D4-TP,E datasheet, TLP5751(D4-TP,E pinout, TLP5751(D4-TP,E application, or TLP5751(D4-TP,E equivalent, this device is selected for high-reliability isolated gate drive where rail-to-rail output, UVLO protection, and VDE-compliant reinforced insulation (EN IEC 60747-5-5) are required in induction cooktops, air conditioner inverters, and industrial motor drives.
Technical Context
The TLP5751(D4-TP,E integrates an infrared LED input stage with a monolithic photo IC detector featuring internal Faraday shielding and a totem-pole buffer output. Its logic-level truth table enables direct interface with microcontroller GPIOs without external level-shifting.
It implements under-voltage lockout (UVLO) with 12.1 V turn-on and 11.1 V turn-off thresholds, supports 15–30 V supply range, and requires a mandatory 1 µF ceramic bypass capacitor between VCC (Pin 6) and GND (Pin 4) placed within 1 cm of the pins to stabilize high-gain amplifier operation and ensure reliable switching.

FAQ
What is the purpose of the 1 µF capacitor required for TLP5751(D4-TP,E?
The 1 µF ceramic capacitor between Pin 6 (VCC) and Pin 4 (GND) stabilizes the internal high-gain linear amplifier in the TLP5751(D4-TP,E photodetector. Without it, the device may exhibit oscillation or improper switching due to supply rail instability. Toshiba specifies placement within 1 cm of the pins to minimize inductance and ensure effective high-frequency decoupling across the -40°C to +110°C operating range.
Does TLP5751(D4-TP,E support both high-side and low-side gate driving?
Yes, the TLP5751(D4-TP,E supports both configurations via its rail-to-rail totem-pole output. When used for high-side driving, it interfaces with bootstrap or isolated DC-DC supplies; for low-side, it connects directly to ground-referenced gate circuits. Its ±1.0 A peak output current and logic-compatible input threshold (≤4 mA) enable flexible integration into half-bridge and three-phase inverter topologies without additional buffering.
What safety certifications apply to TLP5751(D4-TP,E specifically?
The "D4" suffix in TLP5751(D4-TP,E explicitly denotes qualification to EN IEC 60747-5-5 for reinforced insulation. It also carries UL 1577 recognition (File E67349), cUL CSA Component Acceptance (File E67349), and CQC GB4943.1 approval for Japan and Thailand factories - all verified for the exact TLP5751(D4-TP,E ordering variant, not just the base TLP5751 family.
How does the UVLO function in TLP5751(D4-TP,E protect power devices?
The TLP5751(D4-TP,E incorporates an internal under-voltage lockout that disables the output stage when VCC falls below 11.1 V (turn-off) and re-enables it above 12.1 V (turn-on), providing 1.0 V hysteresis. This prevents partial turn-on of IGBTs or MOSFETs during brownout conditions - eliminating shoot-through risk and ensuring clean, full-enhancement gate drive only when supply integrity is confirmed.
Can TLP5751(D4-TP,E replace older 8-pin DIP photocouplers without PCB redesign?
No - the TLP5751(D4-TP,E uses a 6-pin SO6L package (Toshiba 11-4N1A), which has different pin pitch, footprint, and land pattern than legacy 8-pin DIP packages. While it offers 50 % smaller mounting area, direct replacement requires PCB layout revision. Refer to Toshiba's Fig. 15.1 for exact land pattern dimensions and soldering profile requirements for reflow compatibility.
