Product details
Overview
TLP352(D4,F) from Toshiba Electronic Devices & Storage Corporation is a high-speed, high-isolation photocoupler with GaAlAs infrared LED and integrated photo IC in DIP8 through-hole package. It delivers ±2.5 A peak output current, 200 ns max propagation delay, and ±20 kV/µs common-mode transient immunity for robust gate driving of IGBTs and power MOSFETs in industrial inverters and induction cooktops.
For engineers reviewing the TLP352(D4,F) datasheet, TLP352(D4,F) pinout, TLP352(D4,F) application, or TLP352(D4,F) equivalent, this device is selected for high-reliability isolated gate drive where 3750 Vrms isolation, -40 to 125 °C operation, and totem-pole output sourcing/sinking capability are required in safety-critical power conversion systems.
Technical Context
The TLP352(D4,F) integrates an optically coupled GaAlAs LED and high-gain photodetector IC with internal Faraday shield, enabling guaranteed ±20 kV/µs CMTI at up to 125 °C ambient. Its totem-pole output stage supports bidirectional current flow (±2.5 A peak), eliminating external pull-up/pull-down components in gate drive circuits.
It operates from 15–30 V supply with UVLO protection (11.0–13.5 V threshold), requires ≤5 mA input threshold current, and mandates a 0.1 µF bypass capacitor between pins 8 (VCC) and 5 (GND) for stable high-speed switching - critical for clean IGBT turn-on/turn-off in motor drives and home appliance inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 3750 Vrms min - meets reinforced insulation requirements for industrial mains-connected equipment per UL1577 and EN60747-5-5 (D4 option). |
| Output Peak Current | ±2.5 A max - directly drives IGBT/MOSFET gates without external buffer stages in high-power switching applications. |
| Propagation Delay | 200 ns max - enables precise timing control in 50 kHz PWM systems like induction heating and servo motor inverters. |
| CMTI | ±20 kV/µs min - suppresses false triggering during fast dv/dt transients in high-voltage power stages. |
| Operating Temperature | -40 to 125 °C - supports deployment in under-hood automotive auxiliary inverters and sealed industrial enclosures. |
| Supply Voltage Range | 15–30 V - compatible with standard 24 V control rails and provides margin for ripple-induced droop in noisy environments. |
| Threshold Input Current | 5 mA max - ensures reliable turn-on with standard microcontroller GPIO or logic-level drivers without additional current amplification. |
Pinout & Package
Package: DIP8 through-hole (TOSHIBA 11-10C402S), 10.16 mm pitch, creepage/clearance ≥8.0 mm, isolation thickness ≥0.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally unconnected; must remain floating or tied to GND per layout best practice to minimize coupling. |
| 2 | Anode | LED anode input; requires series resistor to limit IF to 5–10 mA for reliable switching and longevity. |
| 3 | Cathode | LED cathode return; connects to MCU/GPIO low-side driver or ground reference. |
| 4 | No Connect | Internally unconnected; leave unpopulated or tie to GND for symmetry and EMI reduction. |
| 5 | GND | Photodetector IC ground reference; must be low-impedance connection to system power ground plane. |
| 6 | VO (Output) | Totem-pole output node; sources/sinks current to drive gate of N-channel IGBT/MOSFET directly. |
| 7 | No Connect | Internally unconnected; no electrical function; avoid routing signals nearby to prevent crosstalk. |
| 8 | VCC | Photodetector supply; requires 0.1 µF ceramic bypass capacitor placed ≤1 cm from pin to GND (pin 5) for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Buffer logic output | Totem-pole configuration enables active high/low drive without external pull resistors - reduces BOM count and PCB area in gate driver designs. |
| UVLO protection | 11.0–13.5 V hysteresis prevents erratic output during brown-out conditions, ensuring safe gate voltage collapse before supply stabilizes. |
| D4 safety certification | EN60747-5-5 qualified variant (TLP352(D4,F)) - certified for reinforced insulation in medical and industrial safety-critical systems. |
| High CMTI | ±20 kV/µs minimum - maintains signal integrity across isolation barrier during rapid bus voltage transients in 600–1200 V DC-link applications. |
| Wide temperature range | -40 to 125 °C operation - validated for use in sealed motor drives, EV charging modules, and induction cooktop control boards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed photocoupler gate drive applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ACPL-332J | SO-6 package (surface-mount), 2.5 A peak output, 250 ns max propagation delay, 5000 Vrms isolation. | Requires rework for SMT assembly; higher isolation but slower switching than TLP352(D4,F). | Select when board space is constrained and SMT process is available; verify layout clearance for 5000 Vrms creepage. |
| HCPL-316J | DIP8 package, 2.5 A peak output, 500 ns max propagation delay, ±15 kV/µs CMTI, 3750 Vrms isolation. | Slower switching and lower CMTI limit suitability in high-frequency (>20 kHz) or high-dv/dt (>10 kV/µs) applications. | Choose for legacy compatibility or cost-sensitive designs where 500 ns delay is acceptable; not recommended for new 50 kHz induction cooktop designs. |
Compared with ACPL-332J and HCPL-316J, the TLP352(D4,F) offers superior speed (200 ns vs. 250/500 ns) and CMTI (±20 kV/µs vs. ±15 kV/µs), making it optimal for high-frequency, high-noise industrial inverters requiring tight timing control and reinforced safety certification.

FAQ
What is the safety certification status of TLP352(D4,F)?
The TLP352(D4,F) is qualified to EN60747-5-5 under Option D4, meeting reinforced insulation requirements for industrial and household appliances. It carries UL1577 (File No. E67349) and cUL CSA Component Acceptance (File No. E67349) approvals. The "(D4,F)" suffix explicitly denotes compliance with this enhanced safety standard, unlike base TLP352 variants.
Does TLP352(D4,F) require an external bypass capacitor?
Yes, TLP352(D4,F) requires a 0.1 µF ceramic capacitor connected between pin 8 (VCC) and pin 5 (GND), placed within 1 cm of both pins. This capacitor stabilizes the internal photodetector IC's high-gain amplifier and prevents improper switching or oscillation - omission causes unreliable gate drive behavior per Toshiba's datasheet Note in Section 6 and 9.
What is the maximum allowable dV/dt on the input side of TLP352(D4,F)?
TLP352(D4,F) does not specify a maximum input-side dV/dt rating. Its input is a GaAlAs LED (pins 2–3), which behaves as a diode - reverse voltage is limited to 5 V max (per Absolute Maximum Ratings). Transient suppression must be implemented externally if the input circuit is exposed to high dv/dt; the device's ±20 kV/µs CMTI applies only to the isolation barrier (input-to-output), not input terminal stress.
Can TLP352(D4,F) drive both high-side and low-side IGBT gates directly?
Yes, TLP352(D4,F)'s totem-pole output (pin 6) can both source and sink up to ±2.5 A peak current, enabling direct drive of low-side IGBT gates (sink mode) and high-side gates when paired with a bootstrap or isolated supply. Its 15–30 V VCC range supports standard gate drive voltages, and UVLO ensures safe disable below 11.0 V - critical for preventing partial turn-on.
What is the difference between TLP352(D4,F) and TLP352F?
TLP352(D4,F) is the EN60747-5-5 Option D4 qualified version of TLP352F, with identical DIP8 package (11-10C402S), pinout, and electrical specs. The "(D4)" denotes formal certification to the higher insulation standard required for safety-critical applications; "(F)" indicates RoHS-compliant construction. Standard TLP352F lacks D4 qualification and cannot be used where EN60747-5-5 compliance is mandated.
