Product details
Overview
TLP250H(TP5,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 TLP250H(TP5,F) datasheet, TLP250H(TP5,F) pinout, TLP250H(TP5,F) application, or TLP250H(TP5,F) equivalent, key selection criteria include guaranteed CMTI performance at 125°C, totem-pole output capability, isolation voltage (3750 Vrms), UVLO threshold behavior, and compatibility with 10–30 V supply rails in high-noise motor control environments.
Technical Context
The TLP250H(TP5,F) integrates an optically isolated GaAlAs LED input stage with a monolithic photodetector IC featuring internal Faraday shielding and a totem-pole output stage capable of both sourcing and sinking current. Its logic-level truth table (H/L input → H/L output) supports direct interface with microcontroller GPIOs without external level-shifting.
It requires a 0.1 µF ceramic bypass capacitor between pins 8 (VCC) and 5 (GND) for stable operation, and mandates VCC ramp rate ≤3.0 V/µs to prevent internal circuit malfunction. UVLO thresholds are specified at 7.5 V (rising) and 8.4 V (falling), with 0.3 V hysteresis ensuring noise-immune power-on reset behavior.

| 5 | GND | Detector ground reference - local star point for 0.1 µF bypass capacitor and output load return. |
| 6 | VO (Output) | Totem-pole output - sources/sinks current to drive gate of IGBT/MOSFET; logic-high ≈ VCC − 2.5 V. |
| 7 | No Connect | Internally unconnected; no electrical function; avoid routing traces to this pin. |
| 8 | VCC | Detector supply - 10–30 V rail; must be decoupled to pin 5 with 0.1 µF ceramic capacitor within 1 cm. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photocoupler gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HCPL-3120 | Higher CMTI (25 kV/µs typ), lower peak output (±2.0 A), SOIC-8 package. | Requires PCB redesign for surface-mount layout; less suitable for high-peak-current IGBTs >30 A. | Select when space-constrained designs prioritize SMT assembly over peak drive strength. |
| ACPL-P349 | Integrated fault feedback, higher supply voltage range (15–30 V), 5 kVrms isolation, SO-6 package. | Lacks totem-pole output - needs external gate resistor network; adds diagnostic capability but increases BOM count. | Select when system-level fault reporting and enhanced safety certification (UL/VDE) are required over raw drive capability. |
Compared with HCPL-3120 and ACPL-P349, the TLP250H(TP5,F) offers superior peak current drive and through-hole mechanical robustness for high-power industrial gate driving, while trading off integrated diagnostics and SMT footprint for proven thermal margin and simplified layout.

FAQ
What is the maximum recommended VCC ramp rate for stable operation of the TLP250H(TP5,F)?
The TLP250H(TP5,F) requires a supply voltage (VCC) rising slope of ≤3.0 V/µs to guarantee stable internal circuit operation. Exceeding this rate may cause improper latch-up or undefined output states during power-up. This specification is explicitly defined in the Recommended Operating Conditions section of the Toshiba datasheet Rev.4.0.B, and applies regardless of temperature or load condition. Always verify VCC slew rate using oscilloscope measurements at pin 8 of the TLP250H(TP5,F) during system startup sequences.
Does the TLP250H(TP5,F) include undervoltage lockout (UVLO), and what are its thresholds?
Yes, the TLP250H(TP5,F) features built-in UVLO with a rising threshold of 7.5 V and falling threshold of 8.4 V, yielding 0.3 V hysteresis. This prevents erroneous gate drive during brown-out conditions by disabling the output until VCC reaches safe operating levels. These values are measured under standard test conditions (IF = 5 mA, VO > 2.5 V for VUVLO+, VO < 2.5 V for VUVLO−) and are guaranteed across the full -40°C to +125°C operating range. The UVLO behavior is integral to the TLP250H(TP5,F)'s reliability in industrial power systems.
Can the TLP250H(TP5,F) directly drive a 1200 V, 50 A IGBT without external components?
The TLP250H(TP5,F) can deliver ±2.5 A peak output current, which is sufficient to drive many 1200 V, 50 A IGBTs in hard-switching applications with moderate gate charge (Qg < 150 nC). However, optimal performance requires a 0.1 µF ceramic bypass capacitor between pins 8 and 5, proper PCB layout minimizing loop inductance, and gate resistor selection matched to desired switching speed and dV/dt control. The TLP250H(TP5,F) does not integrate active Miller clamping or desaturation detection, so external protection remains necessary for fault conditions.
What is the purpose of the internal Faraday shield in the TLP250H(TP5,F)?
The internal Faraday shield in the TLP250H(TP5,F) electrically isolates the input LED and output photodetector IC, enabling guaranteed common-mode transient immunity (CMTI) of ±40 kV/µs minimum. This shielding blocks capacitive coupling of high-frequency noise from high-voltage switching nodes into the logic side, preventing false triggering during fast dv/dt events in inverter half-bridges. The Faraday shield is a structural feature of the TLP250H(TP5,F)'s die construction and contributes directly to its suitability in 600 V+ industrial motor drives.
Is the TLP250H(TP5,F) RoHS-compliant and halogen-free?
Yes, the TLP250H(TP5,F) is RoHS-compliant and halogen-free per Toshiba's environmental specifications. The "(TP5,F)" suffix indicates tape-and-reel packaging with lead-free (LF5) termination and RoHS-compliant materials. Compliance documentation, including Declaration of Conformity and material content reports, is available through Toshiba's official product page and authorized distributors. For full regulatory validation, refer to Toshiba's published environmental data for TLP250H(TP5,F) revision 4.0.B.
