Product details

Overview

IRG4BC15UD-LPBF from Infineon Technologies is a 600 V, 14 A (T_C = 25°C) insulated gate bipolar transistor co-packaged with an ultrafast soft-recovery antiparallel diode in TO-262 (ISOWATT220) package. It delivers V_CE(on) = 2.02 V @ 7.8 A/15 V, 23 nC total gate charge, and 28 ns diode reverse recovery time at 25°C - optimized for 10–30 kHz hard-switching in motor drives and induction heating.

For engineers reviewing the IRG4BC15UD-LPBF datasheet, IRG4BC15UD-LPBF pinout, IRG4BC15UD-LPBF application, or IRG4BC15UD-LPBF equivalent, key selection criteria include its low conduction loss, soft diode recovery for reduced EMI, positive-only gate drive compatibility, and thermal resistance of 2.7 °C/W (junction-to-case, IGBT).

Technical Context

This IGBT employs a trench-gate field-stop structure enabling low V_CE(on) and fast switching with minimal tail current. Its integrated diode features ultra-soft reverse recovery (trr ≤ 42 ns, Qrr ≤ 60 nC at 25°C), minimizing voltage overshoot and snubber requirements in bridge configurations.

The device operates with ±20 V gate voltage rating and exhibits negative temperature coefficient for V_GE(th) (−10 mV/°C), supporting stable parallel operation. Thermal design is enabled by validated R_θJC = 2.7 °C/W (IGBT) and R_θCS = 0.50 °C/W (case-to-sink, greased flat surface).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	600 V - supports DC bus up to 400 V nominal systems with 50% safety margin
I_C (T_C = 25°C)	14 A - continuous current capability at case temperature 25°C, suitable for 1 kW motor inverters
V_CE(on)	2.02 V typ. @ 7.8 A/15 V - enables <1.6 W conduction loss at rated current, reducing heatsink size
Q_g	23 nC typ. - determines gate driver power requirement (~1.7 mW avg. at 20 kHz, 15 V swing)
trr (diode)	28 ns typ. @ 25°C - limits di/dt-induced voltage spikes, allowing snubberless operation in many designs
R_θJC (IGBT)	2.7 °C/W - enables 33 W max power dissipation before junction exceeds 150°C with 80°C case
E_off	0.26 mJ typ. @ 480 V/7.8 A - quantifies turn-off energy loss critical for thermal budget in PWM converters

Pinout & Package

IRG4BC15UD-LPBF uses the TO-262 (ISOWATT220) package: 3-pin, single-ended, isolated mounting flange, lead-free (RoHS-compliant), with creepage/clearance designed for 600 V working voltage.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side current path	Connected to DC+ bus in half-bridge; requires low-inductance layout due to 200 A/µs di/dt capability
Gate (G)	Control terminal for IGBT channel	Accepts 0–15 V logic-level drive; no negative bias required due to high noise immunity
Emitter (E)	Current return path & diode cathode	Shared emitter node for IGBT and antiparallel diode; must be low-impedance for accurate current sensing

Key Features

Feature	Design Value
Ultrafast soft-recovery co-packaged diode	trr ≤ 42 ns, Qrr ≤ 60 nC - eliminates need for external snubbers in 20 kHz inverter bridges
Positive-only gate drive	V_GE(th) = 3.0–6.0 V, no negative bias needed - simplifies gate driver IC selection (e.g., IR2110-compatible)
Low thermal resistance	R_θJC = 2.7 °C/W - supports 33 W dissipation with 80°C heatsink, reducing thermal interface material cost
High dV/dt immunity	Rated for 200 A/µs di/dt during recovery - ensures robust commutation in inductive loads without false turn-on
Lead-free & RoHS compliant	LPbF suffix confirms exemption-compliant Pb-free plating - meets IPC-J-STD-609 Class 2 requirements

Applications

Motor Drive Inverter

Induction Heating Half-Bridge

IC Role / Device Role / Timing Role: Low-side switch handling 12 A peak current; commutates with zero-voltage switching assist.

Use Value: 28 ns trr enables clean diode turn-off before next IGBT turn-on, preventing shoot-through in ZVS transitions.

UPS Output Stage

Solar Microinverter DC-AC

Use Scenario: 1 kVA online UPS output H-bridge converting 360 V DC to 230 V AC at 50 Hz with high-frequency PWM.

IC Role / Device Role / Timing Role: Bidirectional switching element; conducts freewheeling current via integrated diode during dead-time.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IGBT + diode co-packaged switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRG4PH15UD-SPBF	Same 600 V/14 A rating but D2Pak package; R_θJC = 2.2 °C/W; Q_g = 25 nC	Better thermal performance but larger footprint; requires different PCB cutout and mounting hardware	Select when board space permits and junction temperature margin is critical over mechanical fit
FGA25N120ANTD	1200 V/25 A; higher V_CE(on) = 2.7 V; trr = 120 ns; TO-3P package	Designed for 600–800 V DC bus industrial drives; not drop-in due to voltage/current mismatch and pinout	Choose only for 1200 V system upgrades where existing layout cannot accommodate TO-262 footprint

Compared with IRG4PH15UD-SPBF, IRG4BC15UD-LPBF trades 0.5 °C/W higher thermal resistance for TO-262 mechanical compatibility and lower assembly cost; versus FGA25N120ANTD, it offers superior softness and lower gate charge for 400 V systems but lacks 1200 V headroom.

FAQ

What is the maximum recommended gate resistor value for reliable switching at 25 kHz?

A 75 Ω gate resistor is specified in the datasheet for turn-off delay and fall time characterization at 25°C. Using ≥75 Ω ensures E_off remains within 0.26 mJ and prevents excessive dv/dt-induced oscillation. Lower values (e.g., 33 Ω) reduce switching losses but require careful PCB layout to avoid ringing; values below 15 Ω risk gate driver overstress.

Can IRG4BC15UD-LPBF replace IRG4BC15U in existing designs?

Yes - the LPBF suffix indicates lead-free (Pb-free) construction with identical electrical specs, pinout, and thermal performance as the legacy Pb-bearing IRG4BC15U. No layout or drive circuit changes are required; only reflow profile adjustment for Pb-free soldering (peak 260°C) is needed.

Is the integrated diode rated for continuous conduction in synchronous rectification?

No - the diode is rated for I_F = 4.0 A continuous at T_C = 100°C and I_FM = 16 A pulsed, intended for freewheeling and clamping in bridge topologies. For true synchronous rectification, external Schottky or MOSFET-based solutions with higher IF ratings are required.

What is the safe operating area (SOA) limitation at 150°C junction temperature?

At T_J = 150°C, the SOA is limited to 7.8 A at 400 V for 10 µs pulse width (single-pulse). Continuous operation above 4 A at 400 V requires active cooling to maintain T_C ≤ 80°C, as P_D drops to 19 W at T_C = 100°C - verified by the published SOA curves on page 12 of the datasheet.
