Product details
Overview
TLP250HF(D4-LF4,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, ±40 kV/µs common-mode transient immunity, and 3750 Vrms isolation voltage for IGBT/MOSFET gate driving in industrial inverters and home appliance power stages.
For engineers reviewing the TLP250HF(D4-LF4,F) datasheet, TLP250HF(D4-LF4,F) pinout, TLP250HF(D4-LF4,F) application, or TLP250HF(D4-LF4,F) equivalent, key selection criteria include guaranteed operation at 125 °C, totem-pole output architecture, UVLO protection, and VDE-compliant isolation with Option D4 designation.
Technical Context
The TLP250HF(D4-LF4,F) integrates a GaAlAs LED optically coupled to a high-gain photodetector IC with internal Faraday shield, enabling robust noise immunity in high-dv/dt environments such as motor drive half-bridges. Its totem-pole output stage supports bidirectional current sourcing/sinking without external pull-up/pull-down components.
It operates across 10–30 V supply range with UVLO thresholds at 7.5 V (rising) and 8.4 V (falling), and requires a 0.1 µF ceramic bypass capacitor between pins 8 (VCC) and 5 (GND) placed within 1 cm for stable switching. Input threshold current is ≤5 mA, and propagation delay is ≤500 ns (L/H and H/L).
Key Specifications

Applications
| Industrial Inverters | Air Conditioner Inverters |
|---|---|
Use Scenario: Driving IGBT half-bridge legs in variable-frequency drives for pumps, compressors, and fans. IC Role / Device Role / Timing Role: Isolated gate driver providing level-shifted, noise-immune PWM signals to high-side and low-side switches. Use Value: ±40 kV/µs CMTI prevents false triggering during bus voltage transitions; ±2.5 A output ensures fast gate charge/discharge for <500 ns propagation delay. | Use Scenario: Controlling inverter compressor motors in residential and commercial HVAC systems. IC Role / Device Role / Timing Role: Primary-side gate driver isolating microcontroller PWM from 300–400 V DC link. Use Value: 3750 Vrms isolation meets IEC 61800-5-1 requirements; 125 °C rating accommodates ambient temperatures inside sealed outdoor units. |
| Induction Cooktops | IGBT Gate Drivers |
Use Scenario: Driving resonant half-bridge IGBTs in high-frequency (20–50 kHz) cooking coil inverters. IC Role / Device Role / Timing Role: High-speed isolated gate driver synchronizing with zero-voltage switching (ZVS) control logic. Use Value: ≤500 ns propagation delay enables tight timing margin for ZVS; totem-pole output minimizes dead-time uncertainty. | Use Scenario: Direct gate driving of 600–1200 V IGBTs in welding equipment, UPS, and solar inverters. IC Role / Device Role / Timing Role: Reinforced-isolation interface between controller and power stage with integrated UVLO. Use Value: UVLO hysteresis (0.3 V) prevents oscillation near threshold; 10–30 V VCC range simplifies auxiliary supply design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar photocoupler gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP350 | Higher CMTI (±50 kV/µs), lower output current (±0.6 A), SOIC-8 surface-mount package | Better suited for ultra-high-noise environments but requires external gate buffer for >1 A loads | Select when board space is constrained and CMTI >40 kV/µs is mandatory; not drop-in due to package and drive capability mismatch |
| HCPL-3120 | Same DIP8 package, ±2 A output, UL/cUL/VDE certified, 0.5 µs max propagation delay | Compatible with legacy designs using HCPL-3120; slightly lower peak current than TLP250HF(D4-LF4,F) | Preferred for redesigns requiring proven field reliability and identical footprint; verify UVLO thresholds match system requirements |
Compared with TLP350 and HCPL-3120, the TLP250HF(D4-LF4,F) uniquely balances high peak output current (±2.5 A), VDE Option D4 certification, and through-hole DIP8 mechanical robustness-making it optimal for new industrial inverter designs where gate drive strength and safety compliance are co-prioritized.

FAQ
What is the isolation voltage rating of the TLP250HF(D4-LF4,F)?
The TLP250HF(D4-LF4,F) has a minimum isolation voltage rating of 3750 Vrms (AC, 60 s), verified per UL1577, CSA Component Acceptance Service No.5A, and EN60747-5-5 when ordered with Option D4. This rating applies across the full operating temperature range (−40 to +125 °C) and satisfies reinforced insulation requirements for industrial equipment up to 600 V mains.
Does the TLP250HF(D4-LF4,F) require an external bypass capacitor?
Yes, the TLP250HF(D4-LF4,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 detector IC's internal amplifier and prevents improper switching or oscillation-especially critical during high-frequency PWM operation or steep VCC rise times exceeding 3.0 V/µs.
What is the meaning of "(D4-LF4,F)" in the TLP250HF(D4-LF4,F) part number?
The suffix "(D4-LF4,F)" indicates two critical manufacturing options: "D4" denotes VDE certification per EN60747-5-5 (required for European safety compliance), and "LF4" specifies lead forming option 4 (standard gull-wing bend for through-hole insertion). The "F" denotes tape-and-reel packaging (TP4), distinguishing it from bulk or tube variants.
Can the TLP250HF(D4-LF4,F) drive both IGBTs and MOSFETs?
Yes, the TLP250HF(D4-LF4,F) is explicitly designed for both IGBT and power MOSFET gate driving. Its ±2.5 A peak output current, totem-pole output architecture, and 10–30 V supply range enable direct drive of devices with gate charges up to ~100 nC. Toshiba's datasheet lists IGBT gate drivers and MOSFET gate drivers as primary applications, validated across −40 to +125 °C.
What is the common-mode transient immunity (CMTI) specification for the TLP250HF(D4-LF4,F)?
The TLP250HF(D4-LF4,F) guarantees a minimum common-mode transient immunity of ±40 kV/µs at both output high (CMH) and output low (CML) states, measured per JEDEC standards with VCM = 1000 Vp-p, VCC = 30 V, and Ta = 25 °C. This performance is enabled by an internal Faraday shield and is maintained across the full operating temperature range.
