Product details
Overview
TLP250HF(F) from Toshiba Electronic Devices & Storage Corporation is a GaAlAs infrared LED coupled to a high-speed photodetector IC in an 8-pin DIP through-hole package. It delivers ±2.5 A peak output current, ±40 kV/µs common-mode transient immunity, and operates from -40°C to +125°C - enabling robust IGBT and power MOSFET gate driving in industrial inverters and induction cooktops.
For engineers reviewing the TLP250HF(F) datasheet, TLP250HF(F) pinout, TLP250HF(F) application, or TLP250HF(F) equivalent, key selection criteria include guaranteed CMTI performance at 125°C, totem-pole output sourcing/sinking capability, UVLO protection, and isolation voltage compliance with UL1577 and EN60747-5-5 (with Option D4).
Technical Context
The TLP250HF(F) integrates a GaAlAs LED optically coupled to a monolithic photodetector IC featuring internal Faraday shielding and a totem-pole output stage. Its logic-level input interface accepts 5 mA threshold current and drives gate loads with 500 ns max propagation delay (L/H and H/L), while maintaining stable switching under fast-rising VCC slopes (≤3.0 V/µs).
It incorporates undervoltage lockout (UVLO) with 7.5–9.5 V activation range and 0.3 V hysteresis, plus mandatory 0.1 µF bypass capacitance between pins 8 (VCC) and 5 (GND) to stabilize the high-gain amplifier. The device is rated for 3750 Vrms isolation and meets safety standards including UL1577, CSA Component Acceptance, and VDE EN60747-5-5 when specified with Option D4.
Key Specifications

Pinout & Package
The TLP250HF(F) uses an 8-pin DIP through-hole package (TOSHIBA package code 11-10C402S) with 10.16 mm lead pitch and ≥8.0 mm creepage/clearance distances - optimized for high-voltage isolation in industrial PCB layouts.
| 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 - requires series resistor to limit IF to 5–10 mA for reliable turn-on |
| 3 | Cathode | LED cathode - referenced to input-side ground; defines logic polarity (low = ON) |
| 4 | No Connect | Internally unconnected; must remain floating or tied to GND |
| 5 | GND | Detector-side ground reference - return path for output current and bypass capacitor |
| 6 | VO (Output) | Totem-pole output - actively sources and sinks current to drive gate capacitance directly |
| 7 | No Connect | Internally unconnected; must remain floating or tied to GND |
| 8 | VCC | Detector supply - requires 0.1 µF ceramic capacitor to pin 5 for noise immunity and UVLO stability |
Key Features
| Feature | Design Value |
|---|---|
| Buffer logic type (totem-pole) | Enables bidirectional gate drive - eliminates need for external push-pull circuitry in half-bridge configurations |
| UVLO with hysteresis | Prevents erratic switching during brown-out by disabling output below ~7.5 V and re-enabling above ~7.8 V |
| Faraday shield integration | Guarantees ±40 kV/µs CMTI - critical for noise immunity in high-power motor drives and solar inverters |
| Reinforced isolation rating | 3750 Vrms isolation supports functional safety architectures requiring separation between control and power domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HCPL-3120 | Higher CMTI (25 kV/µs typ), lower peak output current (±2.0 A), wider VCC range (15–30 V) | Limited to ≤100 kHz operation due to longer propagation delay (500 ns typ) | Preferred where higher isolation creepage is required but peak current demand is lower |
| ACPL-P349 | Lower threshold current (2.5 mA typ), integrated Miller clamp, no UVLO, 3750 Vrms isolation | Designed for MOSFET-only applications; lacks IGBT-safe negative gate drive capability | Selected when fast turn-off with active Miller clamping is prioritized over UVLO and bipolar gate drive |
Compared with HCPL-3120 and ACPL-P349, the TLP250HF(F) uniquely combines ±2.5 A peak current, guaranteed ±40 kV/µs CMTI at 125°C, and integrated UVLO - making it optimal for high-reliability IGBT gate driving in thermally demanding industrial inverters.

FAQ
What is the maximum recommended supply voltage for the TLP250HF(F)?
The TLP250HF(F) supports a supply voltage (VCC) range of 10 V to 30 V. Absolute maximum rating is 35 V, but operation beyond 30 V risks exceeding safe power dissipation limits and may degrade long-term reliability. For stable UVLO function and thermal margin, 15 V or 20 V is commonly used in IGBT gate driver designs.
Does the TLP250HF(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, prevents oscillation, and ensures proper UVLO operation. Omission causes erratic switching or failure to turn on/off reliably.
What is the purpose of the Faraday shield in the TLP250HF(F)?
The internal Faraday shield in the TLP250HF(F) blocks capacitive coupling between input and output sides, guaranteeing ±40 kV/µs common-mode transient immunity. This prevents false triggering during high dv/dt events in motor drives and inverters - a critical requirement for functional safety in industrial power systems.
Can the TLP250HF(F) drive both IGBTs and MOSFETs?
Yes - the TLP250HF(F) is explicitly designed for both IGBT and power MOSFET gate driving. Its ±2.5 A peak output current, totem-pole architecture, and 500 ns max propagation delay support fast switching of devices up to several hundred amperes, as confirmed in Toshiba's application notes for inverter and induction cooktop designs.
How does the UVLO feature protect the TLP250HF(F) output stage?
The UVLO circuit disables the TLP250HF(F) output when VCC drops below ~7.5 V and re-enables it only after VCC rises above ~7.8 V (0.3 V hysteresis). This prevents weak or partial gate drive that could cause IGBT/MOSFET linear-mode operation, overheating, and catastrophic failure during power supply brown-outs.
