Product details
Overview
TLP352F(TP4,F) from Toshiba Electronic Devices & Storage Corporation is a GaAlAs infrared LED and photo IC-based photocoupler in DIP8 through-hole package, delivering ±2.5 A peak output current, 200 ns max propagation delay, and ±20 kV/µs common-mode transient immunity. It serves as an isolated gate driver for IGBTs and power MOSFETs in industrial inverters and induction cooktops.
For engineers reviewing the TLP352F(TP4,F) datasheet, TLP352F(TP4,F) pinout, TLP352F(TP4,F) application, or TLP352F(TP4,F) equivalent, key selection criteria include guaranteed 125 °C operation, totem-pole output architecture, UVLO protection, and EN60747-5-5 compliance readiness via Option D4.
Technical Context
The TLP352F(TP4,F) integrates a high-gain photodetector IC with internal Faraday shield to achieve ±20 kV/µs CMTI, enabling robust noise immunity in high-dv/dt power stage environments. Its totem-pole output drives both high-side and low-side gates without external pull-up/pull-down components.
It operates across 15–30 V supply voltage with 5 mA max threshold input current and features under-voltage lockout (UVLO) with 11.0–13.5 V activation range and 1.5 V hysteresis - critical for preventing erratic switching during brown-out conditions.
Key Specifications

| Output Peak Current | ±2.5 A max - supports direct drive of medium-power IGBTs and MOSFETs without external buffers |
| Propagation Delay | 200 ns max - enables ≤50 kHz switching in motor control and inverter applications |
| CMTI | ±20 kV/µs min - maintains signal integrity in noisy 600–1200 V DC bus environments |
| Isolation Voltage | 3750 Vrms min - meets reinforced insulation requirements for industrial safety standards |
| Operating Temp | −40 to +125 °C - rated for under-hood and enclosed power module thermal environments |

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, 2.5 A peak output, 0.5 V UVLO hysteresis, no internal Faraday shield | Limited to ≤10 kV/µs CMTI; requires external shielding in high-noise inverters | Preferred for surface-mount, space-constrained designs where CMTI <15 kV/µs suffices |
| SI8261AD-D-IS | Digital isolator with integrated gate driver, 4 A peak output, 5 kVrms isolation, no LED aging concern | Requires external 5 V supply; lacks inherent galvanic isolation for analog feedback paths | Selected when higher drive strength, longer lifetime, or tighter propagation skew (<30 ns) is required |
Compared with ACPL-332J-500E and SI8261AD-D-IS, the TLP352F(TP4,F) delivers superior noise immunity via its internal Faraday shield and maintains proven reliability in high-temperature industrial gate drive roles - making it optimal for legacy-compatible through-hole designs demanding ≥20 kV/µs CMTI.

FAQ
What is the maximum recommended supply voltage for the TLP352F(TP4,F)?
The TLP352F(TP4,F) supports a supply voltage range of 15 to 30 V. Operation above 30 V exceeds absolute maximum ratings and risks permanent damage to the detector IC. For reliable long-term use, maintain VCC within this range and ensure slew rate stays at ≤3.0 V/µs during power-up to prevent internal circuit instability.
Does the TLP352F(TP4,F) require an external bypass capacitor?
Yes - a 0.1 µF ceramic capacitor must be placed between pin 8 (VCC) and pin 5 (GND), located within 1 cm of the pins. This capacitor stabilizes the internal high-gain amplifier and is mandatory for proper switching behavior; omission causes erratic output or failure to toggle under load.
What safety certifications apply to the TLP352F(TP4,F)?
The TLP352F(TP4,F) is UL1577 certified (File No. E67349) and cUL approved. For EN60747-5-5 compliance, the device must be ordered with Option D4 (e.g., TLP352(D4-TP4,F)); standard TLP352F(TP4,F) does not carry VDE approval unless explicitly designated with D4.
Can the TLP352F(TP4,F) drive both N-channel and P-channel MOSFETs directly?
The TLP352F(TP4,F) totem-pole output can source and sink current, enabling direct drive of N-channel MOSFETs in low-side configurations and P-channel devices in high-side setups. However, for high-side N-MOSFET drive, a bootstrap or isolated supply is still required - the TLP352F(TP4,F) provides only signal-level isolation and gate drive, not level-shifting power.
What is the meaning of "(TP4,F)" in the full part number TLP352F(TP4,F)?
In TLP352F(TP4,F), "TP4" denotes tape-and-reel packaging with 1,000 units per reel, and "F" indicates RoHS-compliant, lead-free finish. The base device is TLP352F (10.16-mm pitch DIP8), distinct from the 7.62-mm pitch TLP352 variant.
