Product details
Overview
TLP250HF(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, designed for IGBT and power MOSFET gate driving in industrial inverters and home appliance motor controls. It delivers ±2.5 A peak output current, ±40 kV/µs common-mode transient immunity, and operates from -40°C to +125°C with 3750 Vrms isolation.
For engineers reviewing the TLP250HF(D4-TP4,F) datasheet, TLP250HF(D4-TP4,F) pinout, TLP250HF(D4-TP4,F) application, or TLP250HF(D4-TP4,F) equivalent, key selection criteria include guaranteed CMRI performance at 125°C, totem-pole output drive capability, DIP8 through-hole package with 10.16-mm pitch, and VDE-compliant Option D4 certification for safety-critical systems.
Technical Context
The TLP250HF(D4-TP4,F) integrates an optically coupled GaAlAs LED and a high-gain photodetector IC with internal Faraday shield, enabling robust noise immunity in high-dv/dt environments such as motor drives. Its totem-pole output stage supports bidirectional current sourcing/sinking without external components.
It requires a 0.1-µF ceramic bypass capacitor between pins 8 (VCC) and 5 (GND) for stable operation, and mandates supply voltage ramp rate ≤3.0 V/µs to prevent internal circuit malfunction. The device is rated for 10–30 V supply and 5 mA max threshold input current.

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(F) | Higher 5 A peak output current; 100 ns faster propagation delay; SOIC-6 package | Requires surface-mount layout; better suited for high-density, high-frequency SMPS designs | Select when higher speed and smaller footprint outweigh through-hole assembly preference |
| HCPL-3120 | Same DIP8 package; 2.5 A output; ±25 kV/µs CMRI; UL/cUL only (no VDE) | Lacks EN60747-5-5 certification; not suitable for EU-specified reinforced insulation | Choose for cost-sensitive UL-only industrial applications where VDE compliance is not mandated |
Compared with TLP350(F) and HCPL-3120, the TLP250HF(D4-TP4,F) uniquely combines VDE Option D4 certification, 10.16-mm pitch creepage margin, and proven thermal stability at 125°C - making it the preferred choice for safety-critical, through-hole-based inverter gate drive designs requiring long-term regulatory compliance.

FAQ
What is the isolation voltage rating of the TLP250HF(D4-TP4,F)?
The TLP250HF(D4-TP4,F) has a minimum isolation voltage rating of 3750 Vrms (AC, 60 s), verified per UL1577 and EN60747-5-5 standards. This rating applies to the full isolation barrier between input (pins 1–4) and output (pins 5–8), and is maintained across its operating temperature range of -40°C to +125°C. The device is designated Option D4 to indicate VDE compliance for reinforced insulation.
Does the TLP250HF(D4-TP4,F) require an external bypass capacitor?
Yes, the TLP250HF(D4-TP4,F) requires a 0.1 µF ceramic capacitor placed between pin 8 (VCC) and pin 5 (GND), located within 1 cm of the pins. This capacitor stabilizes the internal photodetector IC's power supply and prevents oscillation or improper switching, especially under high dv/dt conditions. Omission risks unreliable output behavior or latch-up during transient events.
What is the maximum allowable supply voltage ramp rate for the TLP250HF(D4-TP4,F)?
The TLP250HF(D4-TP4,F) requires the supply voltage (VCC) rising slope to be limited to 3.0 V/µs or less. Exceeding this rate may cause internal circuit instability or undefined output states during power-up. This specification is independent of absolute VCC value and applies across the full 10–30 V operating range and -40°C to +125°C temperature span.
How does the TLP250HF(D4-TP4,F) differ from the standard TLP250H?
The TLP250HF(D4-TP4,F) uses a 10.16-mm pitch DIP8 package (vs. 7.62-mm for TLP250H), delivering 8.0 mm creepage/clearance (vs. 7.0 mm), and carries Option D4 marking confirming EN60747-5-5 VDE certification. Both share identical electrical specs, but TLP250HF(D4-TP4,F) is designated for applications requiring higher isolation margins and formal European safety approval.
What is the truth table behavior of the TLP250HF(D4-TP4,F) output?
When the input LED is forward-biased (H input), the output (pin 6) goes high (VO ≈ VCC − 1.0 V typical); when the LED is off (L input), the output goes low (VO ≈ 0.5 V typical). This buffer logic behavior is confirmed by the truth table in the datasheet: Input H → Output H; Input L → Output L. No inversion occurs - the device functions as a non-inverting optically isolated driver.
