Product details
Overview
TLP250H(D4-LF5,F) from Toshiba Electronic Devices & Storage Corporation is a GaAlAs infrared LED-coupled photo IC in DIP8 package, designed as a high-speed, high-gain gate driver for IGBTs and power MOSFETs. It delivers ±2.5 A peak output current, supports 10–30 V supply voltage, and operates across –40 °C to +125 °C with guaranteed ±40 kV/µs common-mode transient immunity.
For engineers reviewing the TLP250H(D4-LF5,F) datasheet, TLP250H(D4-LF5,F) pinout, TLP250H(D4-LF5,F) application, or TLP250H(D4-LF5,F) equivalent, this device is selected for high-reliability isolated gate drive in industrial inverters, air conditioner inverters, and induction cooktops where robust CMTI and totem-pole output sourcing/sinking capability are critical.
Technical Context
The TLP250H(D4-LF5,F) integrates a GaAlAs LED optically coupled to a monolithic photodetector IC with internal Faraday shield, enabling precise isolation barrier performance. Its totem-pole output stage provides bidirectional current drive without external pull-up/pull-down components.
It features under-voltage lockout (UVLO) with thresholds at 7.5 V (rising) and 8.4 V (falling), propagation delay ≤500 ns (L/H and H/L), and requires a 0.1 µF ceramic bypass capacitor between pins 8 (VCC) and 5 (GND) placed within 1 cm for stable operation at high gain.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 3750 Vrms min - meets reinforced insulation requirements for industrial motor drives and appliance inverters. |
| Output Peak Current | ±2.5 A max - directly drives IGBT/MOSFET gates without external buffer stages in <1 kW systems. |
| Common-Mode Transient Immunity | ±40 kV/µs min - suppresses noise-induced false triggering in high-dv/dt switching environments like VFDs. |
| Propagation Delay Time | ≤500 ns max - enables reliable timing control up to 250 kHz switching frequency in PWM gate drive circuits. |
| Supply Voltage Range | 10–30 V - compatible with standard 12 V and 15 V isolated DC-DC supplies used in gate driver bias networks. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood and enclosed inverter applications without derating. |
| Threshold Input Current | ≤5 mA max - ensures low-power microcontroller GPIO compatibility without additional current amplification. |
Pinout & Package
Package: 8-pin DIP through-hole (TOSHIBA designation 11-10C405S), lead-forming option LF5, taping option TP5. RoHS-compliant, Pb-free soldering compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally unconnected; must remain floating or tied to GND per layout best practice. |
| 2 | Anode | LED anode input - connects to MCU GPIO or logic driver via current-limiting resistor. |
| 3 | Cathode | LED cathode - referenced to input-side ground; defines forward current path. |
| 4 | No Connect | Internally unconnected; no PCB trace required. |
| 5 | GND | Detector-side ground reference - return path for output stage and bypass capacitor. |
| 6 | VO (Output) | Totem-pole output - sources/sinks gate current directly to IGBT/MOSFET gate terminal. |
| 7 | No Connect | Internally unconnected; leave unpopulated on PCB. |
| 8 | VCC | Detector supply - powers internal photodetector IC; requires 0.1 µF bypass to pin 5. |
Key Features
| Feature | Design Value |
|---|---|
| Buffer logic type (totem-pole output) | Eliminates need for external pull-up resistors and reduces gate drive loop inductance in high-frequency inverters. |

| High-temperature operation | Rated to +125 °C ambient - supports compact thermal design in sealed inverter modules without forced cooling. |
Applications
| Industrial Inverters | Air Conditioner Inverters |
|---|---|
Use Scenario: Three-phase motor control in HVAC variable-frequency drives operating at 10–20 kHz PWM. IC Role / Device Role / Timing Role: Isolated gate driver providing level-shifted, noise-immune turn-on/turn-off signals to 600 V IGBT half-bridge modules. Use Value: ±40 kV/µs CMTI prevents shoot-through during high dv/dt commutation; ±2.5 A peak current ensures fast gate charge/discharge. |
Use Scenario: Compressor motor drive in residential split-system air conditioners with compact PCB layout and thermal constraints. IC Role / Device Role / Timing Role: Primary-side gate driver isolating MCU control logic from high-side IGBT gate signals in inverter compressor modules.

| Induction Cooktops | IGBT Gate Drivers |
Use Scenario: Resonant half-bridge control in 2–3 kW domestic induction heating systems with rapid load transients. IC Role / Device Role / Timing Role: Isolated driver for synchronous rectification and resonant switch control, handling >100 A peak currents. Use Value: 500 ns max propagation delay ensures tight dead-time control; UVLO avoids gate oscillation during AC line dips. |
Use Scenario: Discrete IGBT gate driving in UPS, welding equipment, and solar string inverters requiring field-serviceable designs. IC Role / Device Role / Timing Role: Direct-coupled gate driver interfacing microcontroller PWM outputs to IGBT bases with galvanic isolation. Use Value: Totem-pole output eliminates external gate resistors; 3750 Vrms isolation meets IEC 62109 and UL 62368-1 creepage/clearance requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP350 | Higher CMTI (±50 kV/µs), same DIP8 package, but lower peak output current (±1.5 A). | Better suited for ultra-noisy SiC-based inverters; insufficient for >1.5 kW IGBT gate drive without buffering. | Select TLP350 when CMTI >40 kV/µs is mandatory and output current demand is ≤1.5 A. |
| HCPL-316J | SOIC-16 package, integrated fault reporting, higher supply voltage range (15–30 V), ±2.5 A output. | Requires PCB redesign for surface-mount layout; adds diagnostic capability not present in TLP250H(D4-LF5,F). | Choose HCPL-316J when board space is constrained and fault feedback to controller is required. |
Compared with TLP350 and HCPL-316J, the TLP250H(D4-LF5,F) offers optimal balance of legacy DIP8 compatibility, full ±2.5 A drive strength, and VDE-certified isolation in cost-sensitive industrial inverter designs where diagnostics are handled externally.

FAQ
What is the isolation voltage rating of the TLP250H(D4-LF5,F)?
The TLP250H(D4-LF5,F) has a minimum isolation voltage rating of 3750 Vrms (AC, 60 s), verified per UL1577 and VDE EN60747-5-5 standards when ordered with Option D4. This rating applies across the full operating temperature range and supports reinforced insulation in industrial motor drives and home appliance inverters.
Does the TLP250H(D4-LF5,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 stabilizes the internal photodetector IC's supply rail and prevents oscillation or improper switching, especially under high-gain or high-frequency conditions.
What is the maximum operating temperature for the TLP250H(D4-LF5,F)?
The TLP250H(D4-LF5,F) is rated for continuous operation from –40 °C to +125 °C ambient temperature. This extended range is validated per datasheet specifications and supports deployment in sealed inverter enclosures, outdoor HVAC units, and induction cooktop control boards without thermal derating.
How does the TLP250H(D4-LF5,F) handle common-mode noise?
The TLP250H(D4-LF5,F) incorporates an internal Faraday shield that guarantees a minimum common-mode transient immunity of ±40 kV/µs. This specification is measured at both output high and low states and ensures reliable operation in high dv/dt environments such as 600 V bus inverters with fast-switching IGBTs.
What is the purpose of the UVLO function in the TLP250H(D4-LF5,F)?
The UVLO (under-voltage lockout) function disables the output stage when VCC drops below approximately 7.5 V (rising threshold) to prevent partial or unstable turn-on of the driven IGBT/MOSFET. This protects power devices from thermal stress during brown-out conditions and ensures clean gate drive only when supply is within safe operating limits.
