Product details
Overview
TLP352F(D4-TP4,F) from Toshiba Electronic Devices & Storage Corporation is a high-speed, high-isolation photocoupler with GaAlAs infrared LED and integrated photo IC output stage in an 8-pin DIP package. It delivers ±2.5 A peak output current, 200 ns max propagation delay, and ±20 kV/µs common-mode transient immunity for driving IGBTs and power MOSFETs in industrial inverters and induction cooktops.
For engineers reviewing the TLP352F(D4-TP4,F) datasheet, TLP352F(D4-TP4,F) pinout, TLP352F(D4-TP4,F) application, or TLP352F(D4-TP4,F) equivalent, this device is selected for high-reliability gate drive isolation where 3750 Vrms isolation voltage, -40 to 125 °C operation, and UVLO protection are required in safety-critical motor control and home appliance systems.
Technical Context
The TLP352F(D4-TP4,F) integrates a GaAlAs LED optically coupled to a high-gain photodetector IC with totem-pole output stage, enabling bidirectional current sourcing/sinking. Its internal Faraday shield ensures ±20 kV/µs CMTI, and UVLO circuitry (11.0–13.5 V threshold with 1.5 V hysteresis) prevents erroneous switching during supply ramp-up.
It operates from 15–30 V supply, requires a 0.1 µF bypass capacitor between pins 8 (VCC) and 5 (GND), and mandates input rise/fall times <0.5 µs. The D4 option confirms EN60747-5-5 certification for reinforced insulation, validated via 3750 Vrms AC/60 s isolation test and ≥8.0 mm creepage/clearance.

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-8 package, 2.5 A peak output, 150 ns max tpHL, but only 5000 Vrms isolation (UL/cUL only, no EN60747-5-5) | Lacks D4 certification; unsuitable where EN60747-5-5 reinforced insulation is mandated (e.g., EU household appliances) | Select only if space-constrained SMT layout is prioritized and EN60747-5-5 compliance is not required. |
| SI8261BBC-C-ISR | Digital isolator with integrated gate driver, 4 A peak output, 200 ns max propagation, 5 kVrms isolation, but requires external level shifters for 3.3 V logic inputs | Higher integration (no LED bias needed), but lacks built-in UVLO and requires separate logic-level translation | Choose when migrating to digital isolation architecture and board space permits additional passives. |
Compared with ACPL-332J-500E and SI8261BBC-C-ISR, the TLP352F(D4-TP4,F) uniquely combines DIP through-hole robustness, EN60747-5-5 certification, and self-contained UVLO-making it optimal for cost-sensitive, safety-regulated industrial and appliance designs where layout simplicity and regulatory alignment are critical.

FAQ
What safety certifications does TLP352F(D4-TP4,F) hold?
TLP352F(D4-TP4,F) is certified to UL1577 (File E67349), cUL CSA Component Acceptance (File E67349), and EN60747-5-5 under Option D4. The D4 designation confirms compliance with reinforced insulation requirements including ≥8.0 mm creepage/clearance, 3750 Vrms isolation, and validated partial discharge performance. This makes TLP352F(D4-TP4,F) suitable for IEC 60335-1 and IEC 60730 Class B applications.
Does TLP352F(D4-TP4,F) require an external bypass capacitor?
Yes, TLP352F(D4-TP4,F) requires a 0.1 µF ceramic capacitor connected between pin 8 (VCC) and pin 5 (GND), placed within 1 cm of the pins. This capacitor stabilizes the internal photodetector IC's high-gain amplifier and prevents oscillation or improper switching. Omission or poor placement of this capacitor will cause erratic output behavior, especially under high dv/dt conditions.
What is the maximum allowable dV/dt on the VCC supply for TLP352F(D4-TP4,F)?
The rising slope of the VCC supply for TLP352F(D4-TP4,F) must be limited to ≤3.0 V/µs to ensure stable internal circuit operation. Exceeding this rate may cause improper UVLO release or metastable output states. This requirement is specified in the Recommended Operating Conditions section of the TLP352F(D4-TP4,F) datasheet and applies regardless of load or temperature.
How does the UVLO function in TLP352F(D4-TP4,F) protect the driven power device?
The UVLO in TLP352F(D4-TP4,F) holds the output low until VCC reaches ≥11.0 V and releases only when VCC exceeds the hysteresis threshold (~12.5 V). This prevents partial turn-on of IGBTs or MOSFETs during power-up or brownout, eliminating shoot-through risk and gate oxide stress. The 1.5 V hysteresis ensures clean, bounce-free transition-critical for reliable operation in TLP352F(D4-TP4,F)-based gate driver circuits.
Can TLP352F(D4-TP4,F) drive both N-channel and P-channel MOSFET gates directly?
TLP352F(D4-TP4,F) features a totem-pole output capable of sourcing and sinking up to ±2.5 A, enabling direct drive of N-channel MOSFET gates (source-connected to GND) and P-channel MOSFET gates (source-connected to VCC) in low-side or high-side configurations. However, for high-side P-channel drive, ensure the gate-source voltage remains within the MOSFET's VGS rating, as TLP352F(D4-TP4,F) does not provide level shifting beyond its VCC rail.
