It is built for driving medium-power IGBTs and MOSFETs in motor drives, inverters, and industrial power supplies where galvanic separation between the control and power stages is mandatory. ## Parametric fit for inverter and SMPS designs With 600 mA peak output and 400 mA source/sink capability, the TLP351H(TP1,F) directly drives gate charges up to ~1.5 µC without an external booster — typical for 600 V / 20-30 A IGBT modules. Rise and fall times are 50 ns typ, keeping switching losses low in the 10-50 kHz range. Common-mode transient immunity is 20 kV/µs minimum, double that of the earlier TLP351 (10 kV/µs). This matters in half-bridge topologies where the high-side switch sees a fast voltage swing — the optocoupler rejects the edge and avoids false turn-on. Propagation delay is 700 ns max with pulse-width distortion held to 500 ns max. For a 20 kHz PWM cycle (50 µs period), the delay is 1.4 % of the period — acceptable for most motor-drive control loops, though a faster part like the TLP352F (200 ns, 2.5 A) would be needed for higher-frequency SiC or GaN stages. ## Active production — sourcing and lifecycle posture RoHS-compliant and approved by CQC, cUR, UR, and VDE. Procurement can quote against a BOM quantity; no imminent obsolescence risk. ## Temperature grade and mounting for industrial environments Surface-mount 8-SMD Gull Wing suits automated assembly; the 1.55 V typical forward voltage at 20 mA max input current is compatible with 3.3 V or 5 V logic outputs through a series resistor.","metaTitle":"TLP351H(TP1,F) Toshiba Optoisolator Gate Driver – 600 mA","metaDescription":"TLP351H(TP1,F) gate drive optocoupler: 600 mA peak output, 3750 Vrms isolation, 125 °C temp range, 20 kV/µs CMTI.

Key differences are a higher peak output (600 mA vs 400 mA), wider operating temperature (125 °C vs 100 °C), and double the common-mode transient immunity (20 kV/µs vs 10 kV/µs). The TLP351H will drop into most TLP351 sockets, but verify the input forward current and supply voltage range match your existing drive circuit."},{"question":"Can the TLP351H(TP1,F) drive IGBT gates directly?","answer":"Yes, the 600 mA peak output and 400 mA source/sink can directly drive the gate of a medium-power IGBT module (e.g., 600 V / 20-30 A class) without an external totem-pole buffer. The 50 ns rise/fall times and 20 kV/µs CMTI are well-suited for hard-switched inverter stages up to 50 kHz. For higher-current modules or faster SiC/GaN devices, consider the TLP352F (2.5 A, 200 ns delay)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TLP351HTP1F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TLP351HTP1F when reusing this data.
