Toshiba Semiconductor and Storage GT20J341,S4X(S

Overview

GT20J341 from Toshiba is a silicon N-channel IGBT with integrated fast recovery diode, rated for 600 V collector-emitter voltage and 20 A DC collector current at Tc = 25°C. It features sixth-generation IGBT technology, low 1.5 V (typ.) saturation voltage at 20 A/15 V gate drive, and TO-220SIS packaging-designed for motor driver inverters requiring efficient switching and thermal robustness.

For engineers reviewing the GT20J341 datasheet, GT20J341 pinout, GT20J341 application, or GT20J341 equivalent, this device is selected for high-reliability industrial motor control where low conduction loss, short-circuit withstand time (5 µs), and integrated FRD simplify inverter half-bridge design.

Technical Context

The GT20J341 employs sixth-generation trench-gate field-stop IGBT structure optimized for balanced conduction and switching losses. Its integrated FRD exhibits 1.5 V (typ.) forward voltage at 20 A and 90 ns reverse recovery time, enabling synchronous commutation without external diode placement.

Thermal design is supported by 2.78 °C/W junction-to-case resistance for the IGBT and 4.23 °C/W for the diode, with safe operating area guaranteed up to 150 °C junction temperature. Dynamic performance includes 0.16 µs turn-on time and 0.35 µs turn-off time under 300 V, 20 A inductive load conditions with 33 Ω gate resistor.

Key Specifications

Pinout & Package

GT20J341 uses the TO-220SIS package (Toshiba designation: 2-10U1S), a single-in-line variant of TO-220 with isolated tab and 3-terminal configuration. The metal tab is electrically isolated from all terminals and serves solely as thermal interface.

FAQ

What is the maximum gate-emitter voltage rating for GT20J341?

The GT20J341 has a maximum gate-emitter voltage (VGES) rating of ±25 V. Exceeding this limit risks irreversible gate oxide breakdown. Gate drive circuits must clamp transients and ensure steady-state bias remains within this window; typical operating gate voltage is +15 V for turn-on and 0 V or −5 V for turn-off to prevent accidental conduction.

Does GT20J341 include an integrated diode, and what are its key parameters?

Yes, GT20J341 integrates a fast recovery diode (FRD) between emitter and collector. Its key parameters include 20 A DC forward current rating, 1.5 V (typ.) forward voltage at 20 A and 25°C, 1.3 V (typ.) at 125°C, and 90 ns reverse recovery time under specified test conditions-enabling self-contained half-bridge operation without external diodes.

What is the short-circuit withstand time of GT20J341, and under what conditions is it specified?

The GT20J341 has a guaranteed short-circuit withstand time (tsc) of 5 µs, measured under conditions of VCC = 300 V, VGG = +15 V/0 V gate drive, and junction temperature ≤125°C. This parameter defines the maximum safe duration the device can endure unclamped short-circuit current before thermal runaway initiates, informing protection circuit response timing.

How does the TO-220SIS package of GT20J341 differ from standard TO-220?

The TO-220SIS package used by GT20J341 features electrical isolation between the metal tab and all three terminals (gate, collector, emitter), unlike standard TO-220 where the tab is internally connected to the collector. This isolation eliminates need for insulating washers or pads in heatsink mounting, simplifying mechanical assembly and improving thermal interface consistency.

What is the typical collector-emitter saturation voltage of GT20J341 at elevated temperature?

The typical collector-emitter saturation voltage (VCE(sat)) of GT20J341 is 1.8 V at IC = 20 A, VGE = 15 V, and Tc = 125°C. This represents a +0.3 V increase over its 25°C value (1.5 V), reflecting positive temperature coefficient behavior critical for current sharing in parallel configurations and thermal stability analysis.
