Product details
Overview
TLP350(TP1,F) from Toshiba Electronic Devices & Storage Corporation is a high-speed, high-isolation photocoupler with infrared LED input and integrated photo IC output stage in an 8-pin DIP through-hole package. It delivers ±2.5 A peak output current, 500 ns max propagation delay, and ±15 kV/µs common-mode transient immunity - designed specifically for driving IGBTs and power MOSFETs in industrial inverters and home appliance motor controls.
For engineers reviewing the TLP350(TP1,F) datasheet, TLP350(TP1,F) pinout, TLP350(TP1,F) application, or TLP350(TP1,F) equivalent, key selection criteria include guaranteed CMRI performance at 100 °C, totem-pole output architecture enabling bidirectional gate drive, isolation voltage rating of 3750 Vrms, and compatibility with 15–30 V supply rails in high-noise power conversion systems.
Technical Context
The TLP350(TP1,F) integrates an infrared LED optically coupled to a high-gain, high-speed photodetector IC with internal Faraday shield - ensuring robust noise rejection in fast-switching power stages. Its totem-pole output stage supports both sourcing and sinking up to ±2.5 A peak current without external buffers.
It operates across –40 °C to +100 °C ambient, features under-voltage lockout (UVLO) with 11.0–13.5 V threshold range, and requires a 0.1 µF bypass capacitor between VCC (Pin 8) and GND (Pin 5) for stable high-gain amplifier operation - a mandatory design requirement per datasheet Section 6.

Equivalent & Alternatives
The following parts are listed as comparable options for similar photocoupler-based gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HCPL-316J | SOIC-16 surface-mount package; higher 2.5 A peak output but requires external UVLO and bias supply sequencing. | Better suited for automated SMT assembly and space-constrained PCBs; lacks integrated Faraday shield - lower CMRI (15 kV/µs typical, not guaranteed). | Select HCPL-316J only if board real estate is limited and system-level noise filtering compensates for reduced guaranteed CMRI. |
| ACPL-P349 | SO-6 package; lower 0.6 A output current; integrated Miller clamp; 1000 Vrms isolation only. | Targeted at low-power MOSFETs (<30 A); includes active Miller clamping to prevent spurious turn-on - not present in TLP350(TP1,F). | Choose ACPL-P349 for cost-sensitive, low-current applications where Miller clamping is required and isolation >3000 Vrms is not mandated. |
Compared with HCPL-316J and ACPL-P349, the TLP350(TP1,F) offers guaranteed ±15 kV/µs CMRI in a through-hole DIP package with integrated UVLO and no external components required for basic operation - making it optimal for ruggedized industrial inverter designs where reliability under high dV/dt and thermal stress is prioritized over miniaturization.

FAQ
What is the maximum recommended operating temperature for TLP350(TP1,F)?
The TLP350(TP1,F) is fully specified and guaranteed for continuous operation from –40 °C to +100 °C ambient temperature. Electrical parameters including propagation delay, output current, and CMRI are validated across this full range. Operation beyond +100 °C requires derating per Toshiba's reliability guidelines and is not supported in standard applications. The TLP350(TP1,F) achieves this rating via optimized die packaging and internal shielding design.
Does TLP350(TP1,F) require an external bypass capacitor, and where must it be placed?
Yes - a 0.1 µF ceramic bypass capacitor is mandatory between Pin 8 (VCC) and Pin 5 (GND) to stabilize the internal high-gain photodetector amplifier. Per Toshiba datasheet Section 6, this capacitor must be placed within 1 cm of both pins to minimize parasitic inductance; failure to do so may cause oscillation or improper switching behavior. The TLP350(TP1,F) will not function reliably without this component.
What safety certifications does TLP350(TP1,F) hold?
The TLP350(TP1,F) is UL-recognized (UL 1577, File No. E67349), cUL-recognized (CSA Component Acceptance Service No. 5A, File No. E67349), VDE-approved to EN IEC 60747-5-5 (when ordered with D4 option), and CQC-approved to GB4943.1. These certifications validate its isolation barrier integrity, construction, and suitability for use in double-insulated industrial equipment - all confirmed on the official Toshiba datasheet Rev. 2.0.
Can TLP350(TP1,F) drive both IGBTs and MOSFETs directly?
Yes - the TLP350(TP1,F) is explicitly designed for direct gate drive of both small-to-medium capacity IGBTs and power MOSFETs. Its ±2.5 A peak output current, totem-pole architecture, and 500 ns max propagation delay enable robust switching of devices up to ~100 A/600 V IGBTs and equivalent MOSFETs without external buffer stages. Toshiba's application notes confirm this usage in inverter schematics for both device types.
What is the purpose of the Faraday shield inside TLP350(TP1,F)?
The internal Faraday shield in the TLP350(TP1,F) provides guaranteed common-mode transient immunity (CMRI) of ±15 kV/µs - a critical feature for operation in high-dV/dt environments like motor drives and induction heating. It blocks capacitive coupling between input and output sides, preventing false triggering caused by rapid voltage transients across the isolation barrier. This shield is a structural element of the TLP350(TP1,F)'s die package, not an optional feature.
