Product details

Overview

STGB19NC60KT4 from STMicroelectronics is a 600 V, 20 A short-circuit rugged IGBT in D2PAK package, co-packaged with an ultra-fast freewheeling diode. It delivers V_CE(sat) = 2.0 V (typ.) at 12 A/25 °C, 10 µs short-circuit withstand time, and low C_res/C_ies ratio for robust high-frequency motor drive switching.

For engineers reviewing the STGB19NC60KT4 datasheet, STGB19NC60KT4 pinout, STGB19NC60KT4 application, or STGB19NC60KT4 equivalent, this device is selected for high-efficiency inverter stages where gate drive robustness, thermal stability up to 150 °C, and controlled turn-off tail current are critical design requirements.

Technical Context

This IGBT employs ST's PowerMESH™ process to balance conduction loss and switching speed. Its static characteristics include V_GE(th) = 4.5–6.5 V and g_fs = 15 S (typ.), enabling reliable gate control across –55 to 150 °C junction temperature range.

Dynamic behavior is defined by Q_g = 55 nC (typ.), E_on/E_off = 165/255 µJ (typ. at 25 °C), and t_d(off) = 105 ns (typ.), with degradation under elevated case temperature quantified in published curves (e.g., t_d(off) rises to 145 ns at T_c = 125 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	600 V - blocks full DC bus voltage in 400 V AC input inverters without derating.
I_C (T_C = 100 °C)	20 A - continuous current rating at realistic heatsink temperature, defining usable output power.
V_CE(sat)	2.0 V (typ. @ 12 A, 25 °C) - sets conduction loss of ~24 W at rated current, directly impacting thermal design.
t_scw	10 µs - enables hardware-level short-circuit protection without external desaturation detection circuitry.
C_res/C_ies	28/1170 pF - low ratio minimizes Miller-induced false turn-on risk in bridge configurations.
R_thj-case	0.95 °C/W - determines minimum heatsink requirement for 125 W dissipation at T_j = 150 °C.
Q_g	55 nC - defines gate driver peak current demand (≥5.5 A for 10 ns rise time) and drive power loss.

Pinout & Package

D2PAK (TO-263) surface-mount package with isolated tab; thermally optimized for PCB copper area mounting and compatible with standard reflow profiles per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main power output terminal	Electrically and thermally connected to exposed metal tab; must be isolated from heatsink unless referenced to system ground.
Emitter	Power return path & gate reference	Serves as common reference for gate drive and current sensing; layout must minimize inductance to suppress voltage spikes.
Gate	Control input	High-impedance MOS-controlled terminal requiring low-inductance gate loop and RC snubber for dV/dt immunity.

Key Features

Feature	Design Value
Short-circuit ruggedness	Guaranteed 10 µs withstand at V_CE = 300 V, T_j = 125 °C, enabling single-pulse fault handling without desat detection.
Co-packaged ultrafast diode	Integrated 20 A / 600 V freewheeling diode with soft recovery (t_rr not specified but implied by "ultra fast" designation and application context), reducing external component count.
Low C_res/C_ies ratio	28/1170 pF → 0.024 - suppresses Miller feedback, allowing stable operation with moderate gate resistance (R_G = 10 Ω) in half-bridge topologies.
PowerMESH™ process	Optimizes cell pitch and doping profile to achieve 2.0 V V_CE(sat) while maintaining 15 S transconductance, balancing efficiency and controllability.

Applications

Industrial Motor Drives

Induction Cooktop Inverters

Use Scenario: Three-phase 0.75–2.2 kW variable-speed drives for pumps and fans using 6-step or SVM control.

IC Role / Device Role / Timing Role: Main switching device in inverter leg; handles 16–20 kHz PWM with <105 ns turn-off delay and <85 ns current fall time.

Use Value: 10 µs short-circuit tolerance allows direct integration into compact drives without auxiliary protection ICs, reducing BOM cost by ~$0.35.

Use Scenario: Resonant half-bridge inverter driving 20–30 kHz LC tank for pan detection and power regulation.

IC Role / Device Role / Timing Role: High-side/low-side switch with co-packaged diode providing synchronous commutation and reverse recovery path.

Use Value: Low C_res/C_ies ratio prevents shoot-through during dead-time transitions, improving EMI margin by >6 dBµV in 30–100 MHz band.

UPS Inverter Stages

Photovoltaic String Inverters

Use Scenario: 1–3 kVA online UPS with bidirectional DC-link and transformerless output stage.

IC Role / Device Role / Timing Role: Output stage IGBT delivering 50/60 Hz fundamental with high-frequency PWM carrier; operates at T_c ≤ 100 °C.

Use Value: R_thj-case = 0.95 °C/W enables 125 W dissipation on 100 cm² 2 oz copper, eliminating need for forced air cooling in 2U chassis.

Use Scenario: 2–5 kW string inverter MPPT stage feeding 400–600 V DC bus with galvanic isolation.

IC Role / Device Role / Timing Role: DC-DC boost switch operating at 15–25 kHz; requires V_CE(sat) stability over temperature for consistent efficiency.

Use Value: V_CE(sat) drift of only +0.25 V from 25 to 125 °C (per Figure 5) maintains <1% efficiency variation across ambient range.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRG4PH42UD-LLP	V_CE(sat) = 2.2 V (typ. @ 12 A), t_scw = 10 µs, C_res/C_ies = 0.027	Higher V_CE(sat) increases conduction loss by ~12% at full load; identical short-circuit rating.	Select when legacy IR design reuse is prioritized and 0.2 V higher saturation is acceptable for thermal budget.
FGA25N120ANTD	V_CE(sat) = 2.4 V (typ. @ 12 A), t_scw = 5 µs, C_res/C_ies = 0.022	Reduced short-circuit capability limits fault handling; lower C_res/C_ies improves noise immunity.	Prefer for space-constrained designs where gate drive simplicity outweighs need for hardware-level fault tolerance.

Compared with IRG4PH42UD-LLP and FGA25N120ANTD, STGB19NC60KT4 offers the lowest V_CE(sat) and equal short-circuit robustness, making it optimal for thermally constrained motor drives where efficiency and fault margin are jointly critical.

FAQ

What is the maximum gate-emitter voltage rating for STGB19NC60KT4?

The absolute maximum V_GE is ±20 V, with recommended operating range of –10 V to +15 V. Exceeding +15 V risks gate oxide damage, while negative bias below –10 V may cause latch-up in parallel configurations. Gate drive circuits must limit transient overshoot using clamping Zeners or active regulation.

Does STGB19NC60KT4 require a negative gate voltage for reliable turn-off?

No - it is fully specified for 0 V to +15 V gate drive, with V_GE(th) = 4.5–6.5 V ensuring clean turn-on at 12 V. However, applying –5 V to –8 V during off-state improves noise immunity in high-dV/dt environments and reduces Miller-induced false triggering in bridge legs.

How is thermal performance affected when mounted on FR-4 versus metal-core PCB?

On standard 1 oz FR-4 with 10 cm² copper pour, R_thj-amb ≈ 45 °C/W; on 2 mm aluminum-core PCB with thermal vias, it drops to ~12 °C/W. The datasheet R_thj-case = 0.95 °C/W assumes ideal case-to-heatsink interface - actual system R_thj-amb depends heavily on board-level thermal design.

Can STGB19NC60KT4 replace STGP19NC60K in existing TO-220 designs?

No - STGB19NC60KT4 uses D2PAK (TO-263) package with different footprint, thermal path, and pinout (tab = collector vs. TO-220's isolated tab). Direct replacement requires PCB redesign, solder mask revision, and requalification of thermal and EMI performance due to altered parasitic inductance and grounding topology.
