Product details

Overview

IRGB14C40LPBF from Infineon Technologies is a 400 V, 20 A, 125 W trench-gate field-stop IGBT in TO-247AC package, featuring 1.35–1.55 V V_CE(on) at 10 A/4.5 V, 27 nC total gate charge, and integrated R₂=10–30 kΩ gate-to-emitter resistor for enhanced short-circuit ruggedness. It is designed for hard-switched industrial motor drives operating up to 175 °C junction temperature.

For engineers reviewing the IRGB14C40LPBF datasheet, IRGB14C40LPBF pinout, IRGB14C40LPBF application, or IRGB14C40LPBF equivalent, key selection criteria include clamped inductive switching capability (11.5 A @ 4.7 mH), 120 µs short-circuit withstand time at 16 V, and thermal resistance R_θJC = 1.2 °C/W for heatsink-limited power conversion stages.

Technical Context

This IGBT employs a field-stop trench-gate structure optimized for low conduction loss and controlled switching behavior in 400 V DC-link applications. Its built-in gate-emitter resistor (R₂) and gate series resistor (R₁ = 75 Ω) provide intrinsic gate control stability and reduce external component count in gate driver circuits.

The device supports self-clamped avalanche operation with validated energy handling up to 15.5 A at L = 0.7 mH and 120 µs short-circuit robustness under V_CC = 16 V, enabling reliable operation in unclamped inductive load switching without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	400 V - Maximum clamped collector-emitter voltage; defines safe blocking capability in 400 V bus systems
I_C (T_C = 25°C)	20 A - Continuous current rating at case temperature 25°C; sets baseline conduction capacity
V_CE(on)	1.35–1.55 V @ 10 A/4.5 V - Low saturation voltage enables <1.6 W conduction loss at rated current
Q_g	27 nC - Total gate charge determines required gate driver peak current and switching loss trade-off
R_θJC	1.2 °C/W - Junction-to-case thermal resistance; enables 125 W dissipation with ≤150 °C case rise
t_SC	120 µs @ V_CC = 16 V - Short-circuit withstand time defines fault-clearance window for protection circuitry
I_L (L = 4.7 mH)	11.5 A @ T_C = 25°C - Self-clamped inductive switching current; validates snubberless operation in motor phase legs

Pinout & Package

IRGB14C40LPBF is housed in a TO-247AC package with isolated tab (collector-connected). The package features 3-pin through-hole mounting, 2.54 mm lead pitch, and 15.8 mm × 20.3 mm footprint, optimized for high-power PCB heatsinking and forced-air cooling.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main power output terminal	Electrically connected to metal tab; requires insulated mounting when heatsink is grounded
Gate	Control input	Driven by gate driver; internal R₁ = 75 Ω limits di/dt and reduces ringing risk
Emitter	Power return and reference node	Serves as common source for gate drive return and current sensing; internal R₂ = 10–30 kΩ ensures gate discharge path

Key Features

Feature	Design Value
Field-stop trench-gate structure	Enables simultaneous optimization of V_CE(on), Q_g, and softness-reducing E_off by ~20% vs planar IGBTs
Integrated gate-emitter resistor (R₂)	10–30 kΩ provides fail-safe gate discharge during UVLO or driver fault, eliminating external pull-down
Self-clamped avalanche capability	Validated up to 15.5 A at L = 0.7 mH; removes need for external clamping diodes in flyback or H-bridge freewheeling
Short-circuit ruggedness	120 µs withstand time at 16 V DC-link allows use with standard microcontroller-based protection without dedicated desat detection

Applications

Industrial Motor Drives

Uninterruptible Power Supplies

Use Scenario: Three-phase inverter stage in 3–7.5 kW HVAC compressors with 400 V DC-link.

IC Role / Device Role / Timing Role: Main switching device in each leg; operates at 8–16 kHz PWM frequency with hard commutation.

Use Value: 1.35 V V_CE(on) reduces conduction loss by ~18% vs comparable 450 V IGBTs, improving system efficiency at partial load.

Use Scenario: Inverter output stage in online double-conversion UPS delivering clean 230 V AC from 400 V battery bank.

IC Role / Device Role / Timing Role: High-side switch in full-bridge topology; handles bidirectional power flow during battery charging and inverting.

Use Value: 120 µs short-circuit withstand time enables deterministic fault response using 10 µs-resolution MCU timers-no external desat circuit needed.

Solar String Inverters

Induction Heating Generators

Use Scenario: DC–AC stage in 5 kW string inverter with transformerless topology and 400 V PV input.

IC Role / Device Role / Timing Role: Half-bridge switch subjected to repetitive unclamped inductive transients during MPPT perturbation.

Use Value: Self-clamped avalanche current of 11.5 A at 4.7 mH validates operation without snubber capacitors-reducing BOM cost and layout area.

Use Scenario: Resonant half-bridge in 3.5 kW induction cooktop operating at 20–50 kHz.

IC Role / Device Role / Timing Role: High-frequency switching element with zero-voltage switching assist; requires low Q_gc and stable V_GE(th) over temperature.

Use Value: Gate threshold voltage shift of only 0.75–1.8 V across –40 to 150 °C ensures consistent turn-on timing and prevents shoot-through at elevated temperatures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STGP40H60DF	600 V rating, higher V_CE(on) (1.8 V), no integrated R₂, 35 nC Q_g	Better for 600 V bus systems; requires external gate pull-down and snubber for same inductive stress	Select when higher voltage margin is needed and gate driver has stronger sourcing capability
IXYS IXGH40N60B3	600 V, 40 A, 2.2 V V_CE(on), no field-stop trench, 65 nC Q_g	Higher current rating but significantly higher conduction and switching losses; not self-clamped	Choose only if 600 V blocking and 40 A continuous current are mandatory and thermal headroom exists

Compared with STGP40H60DF and IXGH40N60B3, IRGB14C40LPBF delivers lower conduction loss, integrated gate termination, and validated self-clamping-making it optimal for cost-sensitive 400 V industrial inverters where reliability and BOM simplification are prioritized over voltage headroom.

FAQ

What is the maximum allowable gate-emitter voltage for IRGB14C40LPBF?

The absolute maximum V_GE is ±20 V, with clamped rating at ±12 V per datasheet Figure 4. Operation above ±12 V risks permanent gate oxide damage. Recommended drive range is –5 V to +15 V, with +15 V ensuring full enhancement and –5 V providing noise-immune turn-off margin.

Does IRGB14C40LPBF require an external gate resistor?

Yes-although R₁ = 75 Ω and R₂ = 10–30 kΩ are integrated, an external series gate resistor (typically 10–47 Ω) remains necessary to control dV/dt, limit peak gate current, and damp parasitic oscillation. The internal R₁ alone cannot suppress ringing in typical PCB layouts.

Can IRGB14C40LPBF be used in parallel configurations?

Parallel operation is not recommended due to positive temperature coefficient of V_CE(on) being insufficient for current sharing-measured drift is only ~0.5 mV/°C, below the 1–2 mV/°C typically required for stable paralleling without active current balancing.

What is the meaning of "P" in the part number suffix LPBF?

The "P" denotes lead-free plating per JEDEC J-STD-609, and "BF" indicates RoHS-compliant packaging. The full suffix "LPBF" confirms compliance with both lead-free soldering requirements and EU RoHS Directive 2011/65/EU, including exemption 7a for high-melting-temperature solder alloys.
