Product details
Overview
GT40QR21 from Toshiba is a 1200 V, 40 A silicon N-channel RC-IGBT with monolithically integrated freewheeling diode, optimized for voltage-resonant inverter switching in industrial induction heating systems. It delivers VCE(sat) = 1.9 V (typ.) at IC = 40 A and Tj = 25 °C, supports 175 °C maximum junction temperature, and features 0.20 µs typical fall time.
For engineers reviewing the GT40QR21 datasheet, GT40QR21 pinout, GT40QR21 application, or GT40QR21 equivalent, key selection criteria include its 6.5th-generation RC-IGBT architecture, TO-3P(N) package thermal resistance of 0.65 °C/W, and dedicated suitability for resonant-mode inverters requiring low conduction loss and fast turn-off.
Technical Context
The GT40QR21 implements a 6.5th-generation trench-gate field-stop IGBT structure with co-integrated fast-recovery freewheeling diode on a single die. Its static characteristics include positive temperature coefficient for VCE(sat), enabling inherent current sharing in parallel configurations.
Dynamic behavior is defined by resistive-load switching times (tf = 0.20 µs typ.) and inductive-load turn-off energy (Eoff = 0.29 mJ typ. at Tc = 125 °C), with gate-emitter voltage rating of ±25 V and input capacitance Cies = 1500 pF at 10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCES | 1200 V - Withstands DC bus voltages up to 1200 V in resonant inverter topologies without breakdown. |
| IC (DC) | 40 A - Continuous collector current capability at Tc = 25 °C, defining steady-state power handling in induction heater output stages. |
| VCE(sat) | 1.9 V (typ.) at IC = 40 A - Low saturation voltage minimizes conduction loss and heatsink requirements in high-efficiency inverters. |
| tf | 0.20 µs (typ.) - Fast fall time enables high-frequency operation (>20 kHz) in zero-voltage-switching (ZVS) resonant circuits. |
| Tj(max) | 175 °C - High junction temperature rating allows compact thermal design and operation under sustained overload conditions. |
| Rth(j–c) | 0.65 °C/W - Low thermal resistance from junction to case enables effective heat transfer to heatsinks in TO-3P(N) mounting. |
| trr (FWD) | 0.60 µs (typ.) at IF = 15 A - Fast reverse recovery of integrated diode reduces switching loss and EMI in bidirectional current paths. |
Pinout & Package
GT40QR21 is housed in a TO-3P(N) package (Toshiba designation: 2-16C1S), featuring insulated metal tab for direct heatsink mounting and 4.6 g typical mass. The package provides robust thermal performance and high-voltage isolation suitable for industrial power modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate | Control terminal requiring ±25 V gate drive; low input capacitance (1500 pF) eases driver design and reduces gate loss. |
| 2 | Collector | Main high-side power terminal connected to DC bus; rated for 1200 V blocking and 80 A peak current. |
| 3 | Emitter | Power return path and reference for gate drive; shared emitter node for IGBT and integrated FWD enables compact layout. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic RC-IGBT | Single-die integration of IGBT and fast-recovery diode eliminates discrete diode placement, reducing parasitic inductance and layout complexity. |
| Enhancement-mode operation | Normally-off behavior ensures safe default state during gate drive failure or startup, critical for industrial safety compliance. |
| High-speed switching | 0.20 µs tf and 0.40 µs toff support ZVS operation at 20–50 kHz, enabling smaller passive components in resonant tank designs. |
| Low VCE(sat) temperature stability | VCE(sat) increases only to 2.50 V at IC = 40 A and Tj = 175 °C, maintaining predictable conduction loss across full operating range. |
| 175 °C junction rating | Enables derated operation at elevated ambient temperatures (e.g., enclosed control cabinets) without forced air cooling. |
Applications
| Induction Heating Inverters | Resonant DC-AC Converters |
|---|---|
Use Scenario: Medium-frequency (20–100 kHz) series-resonant inverters for industrial metal heating, melting, and hardening. IC Role / Device Role / Timing Role: Main switching device in half-bridge configuration, conducting high-current AC through resonant tank.

Equivalent & Alternatives
The following parts are listed as comparable options for similar IGBT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXGN40N120B3 | 1200 V/40 A, TO-247 package, separate diode, tf = 0.18 µs, Rth(j–c) = 0.55 °C/W | Requires external FWD; lower thermal resistance but higher layout complexity and stray inductance. | Select when maximum thermal performance is prioritized and discrete diode integration is acceptable. |
| Infineon IKW40N120H3 | 1200 V/40 A, TO-247-3L, co-packaged diode, tf = 0.22 µs, VCE(sat) = 2.1 V (typ.) | Higher VCE(sat) increases conduction loss; same resonant inverter use case but lower efficiency at full load. | Select when supply chain availability favors Infineon and 0.2 V higher saturation voltage is tolerable. |
Compared with IXGN40N120B3 and IKW40N120H3, the GT40QR21 uniquely integrates the freewheeling diode in the same die, reducing layout parasitics and simplifying PCB routing for resonant inverters-while maintaining competitive VCE(sat) and thermal resistance within its TO-3P(N) form factor.

FAQ
What is the maximum junction temperature rating for the GT40QR21?
The GT40QR21 has a maximum junction temperature rating of 175 °C, verified per Toshiba's Absolute Maximum Ratings table. This allows operation at elevated ambient temperatures and supports thermal derating strategies in enclosed industrial enclosures. The GT40QR21 must not exceed this limit under any condition, including transient overloads, as confirmed in the datasheet's Note 1 and Thermal Characteristics section.
Does the GT40QR21 include an integrated freewheeling diode?
Yes, the GT40QR21 is an RC-IGBT with a monolithically integrated fast-recovery freewheeling diode on the same silicon die. This is explicitly stated in the Features section as "(2) The RC-IGBT consists of a freewheeling diode monolithically integrated in an IGBT chip." The diode exhibits trr = 0.60 µs (typ.) at IF = 15 A, confirming co-integration and functional validation in the Electrical Characteristics table.
What package type does the GT40QR21 use, and what are its mechanical identifiers?
The GT40QR21 uses the TO-3P(N) package, also designated by Toshiba as 2-16C1S. Its mechanical specifications include a 4.6 g typical mass, insulated metal tab for heatsink mounting, and three terminals: Gate (Pin 1), Collector (Pin 2), Emitter (Pin 3). Package dimensions and marking details are documented in the "Package Dimensions" and "Marking" sections of the official datasheet Rev. 2.0.A.
What is the typical collector-emitter saturation voltage of the GT40QR21 at rated current?
The typical collector-emitter saturation voltage of the GT40QR21 is 1.9 V at IC = 40 A, VGE = 15 V, and Tj = 25 °C, as specified in the Electrical Characteristics table under VCE(sat)(4). At elevated junction temperature (Tj = 175 °C), VCE(sat) rises to 2.50 V (typ.), reflecting the device's positive temperature coefficient and enabling inherent current balancing in parallel configurations.
Is the GT40QR21 suitable for hard-switching applications?
No-the GT40QR21 is explicitly designated for voltage-resonant inverter switching applications, as stated in the Applications section. Its optimized dynamic parameters (e.g., tf = 0.20 µs, Eoff = 0.29 mJ) and thermal design assume ZVS operation. Hard-switching would exceed safe operating area limits and accelerate degradation, per Toshiba's RESTRICTIONS ON PRODUCT USE clause specifying "The product(s) described herein should not be used for any other application."
