Product details
Overview
TLP5774(D4-TP,E from Toshiba Electronic Devices & Storage Corporation is a reinforced-insulation photocoupler integrating an infrared LED and high-speed photo IC in a 6-pin SO6L package. It delivers ±4.0 A peak output current, 150 ns max propagation delay, ±35 kV/µs common-mode transient immunity, and operates across –40°C to +110°C - enabling direct microcontroller drive in compact motor drivers and industrial inverters.
For engineers reviewing the TLP5774(D4-TP,E datasheet, TLP5774(D4-TP,E pinout, TLP5774(D4-TP,E application, or TLP5774(D4-TP,E equivalent, this device is selected for high-noise industrial gate driving where rail-to-rail output, low 2 mA threshold input current, and 5000 Vrms isolation voltage are critical design requirements.
Technical Context
The TLP5774(D4-TP,E implements a totem-pole buffer logic output stage with rail-to-rail swing, supporting direct connection to IGBT/MOSFET gates without external buffers. Its internal Faraday shield ensures guaranteed ±35 kV/µs CMTI performance under fast-switching conditions in inverter half-bridges.
This photocoupler operates with 10–30 V supply voltage and features under-voltage lockout (UVLO) with 7.5 V turn-on and 2 V hysteresis, preventing erratic switching during power ramp-up. The D4 option certifies compliance with EN IEC 60747-5-5 for reinforced insulation in safety-critical AC servo and PV conditioning systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms min - meets reinforced insulation requirements per UL 1577, VDE EN IEC 60747-5-5, and GB4943.1. |
| Output Peak Current | ±4.0 A max - drives high-gate-charge IGBTs/MOSFETs directly without external amplification. |
| Propagation Delay | 150 ns max - enables precise timing control in 50 kHz switching applications like industrial inverters. |
| Common-Mode Transient Immunity | ±35 kV/µs min - suppresses noise-induced false triggering in high-dV/dt motor drive environments. |
| Threshold Input Current | 2 mA max - allows direct interface with 3.3 V/5 V microcontrollers without current-limiting resistor redesign. |
| Supply Voltage Range | 10–30 V - supports wide-bus industrial systems and accommodates ripple without UVLO dropout. |
| Operating Temperature | –40°C to +110°C - rated for under-hood and enclosed cabinet deployment in AC servos and sewing machines. |
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 anode input | Connects to MCU GPIO or driver stage; requires series resistor to limit IF ≤8 mA. |
| 2: N.C. | No connection | Internally unconnected; must remain floating - no PCB trace or pad tie. |
| 3: Cathode | LED cathode return | Completes LED forward path; ties to ground or active-low driver sink. |
| 4: GND | Detector ground reference | Return for VCC bypass capacitor (1 µF ceramic, placed within 1 cm); critical for noise immunity. |
| 5: VO | Output signal terminal | Rail-to-rail totem-pole output; drives gate directly - VO = VCC when high, VO = GND when low. |
| 6: VCC | Detector supply input | 10–30 V logic-side supply; UVLO active below 7.5 V; bypass capacitor mandatory between pins 6 and 4. |
Key Features
| Feature | Design Value |
|---|---|
| Buffer logic output | Totem-pole configuration eliminates need for external push-pull gate driver stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gate driver isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP5772(D4-TP,E | Same SO6L package and D4 certification, but ±2.5 A peak output current (vs. ±4.0 A). | Suitable for lower-power motor drivers (<1 kW) where gate charge is smaller; not recommended for 1200 V IGBTs in industrial inverters. | Select TLP5772(D4-TP,E only if system gate drive requirement is ≤2.5 A and board layout re-use is prioritized. |
| Si8273ACD-IS | Capacitive isolation, 4 A peak output, but 2.5 kVrms isolation (vs. 5 kVrms) and no VDE EN IEC 60747-5-5 certification. | Acceptable in non-safety-certified consumer-grade inverters; insufficient for UL/VDE-reinforced insulation requirements in PV or servo systems. | Choose Si8273ACD-IS only for cost-sensitive, non-certified designs where 2.5 kVrms isolation suffices and CMTI ≥35 kV/µs is verified. |
Compared with TLP5774(D4-TP,E, the TLP5772(D4-TP,E offers identical safety certification and footprint but reduced drive strength, while the Si8273ACD-IS trades isolation robustness and regulatory compliance for higher integration density - making TLP5774(D4-TP,E the sole choice for certified, high-noise, high-power industrial gate driving.

FAQ
What safety certifications apply to the TLP5774(D4-TP,E?
The TLP5774(D4-TP,E carries UL 1577 recognition (File No. E67349), cUL CSA Component Acceptance (File No. E67349), VDE approval to EN IEC 60747-5-5 and EN IEC 62368-1, and CQC certification to GB4943.1. The "(D4" suffix explicitly denotes qualification to the EN IEC 60747-5-5 reinforced insulation standard, required for PV inverters and AC servos.
Why is a 1 µF capacitor required between VCC and GND on the TLP5774(D4-TP,E?
A 1 µF ceramic bypass capacitor between pin 6 (VCC) and pin 4 (GND) is mandatory per Toshiba's recommended operating conditions to stabilize the internal high-gain amplifier and prevent oscillation or improper switching. Placement within 1 cm of the pins is required to maintain ±35 kV/µs CMTI performance - omitting or misplacing this capacitor causes unreliable output behavior in high-noise motor drive environments.
Can the TLP5774(D4-TP,E drive a 1200 V IGBT directly?
Yes - the TLP5774(D4-TP,E delivers ±4.0 A peak output current and rail-to-rail VO swing, enabling direct gate drive of typical 1200 V, 75 A IGBT modules used in industrial inverters. Its 150 ns max propagation delay and ±35 kV/µs CMTI ensure timing accuracy and noise immunity even at high dV/dt rates near the DC bus.
What is the meaning of "(D4-TP,E" in the full part number TLP5774(D4-TP,E?
In TLP5774(D4-TP,E, "D4" indicates qualification to EN IEC 60747-5-5 for reinforced insulation; "TP" denotes tape-and-reel packaging (1500 pcs/reel); and "E" signifies RoHS-compliant, lead-free construction. This full ordering code identifies the safety-certified, production-ready, surface-mount variant - distinct from non-D4 or magazine-packaged versions.
Does the TLP5774(D4-TP,E support 3.3 V microcontroller input directly?
Yes - the TLP5774(D4-TP,E has a maximum threshold input current (IFLH) of 2 mA and typical input forward voltage of 1.65 V at 8 mA, allowing direct connection to 3.3 V GPIOs using a ~1.5 kΩ series resistor. This eliminates level shifters or buffer stages, simplifying design in compact motor drivers and servo controllers where board space is constrained.
