Product details

Overview

IKA03N120H2 from Infineon Technologies is a 1200V, 3A high-speed IGBT with integrated anti-parallel Emitter Controlled HE diode in PG-TO220-3-31/34 FullPAK package, optimized for TV horizontal line deflection circuits, featuring 0.15mJ turn-off energy at Tj=25°C, 2.2V V_CE(sat) at 25°C, and soft fast recovery diode behavior.

For engineers reviewing the IKA03N120H2 datasheet, IKA03N120H2 pinout, IKA03N120H2 application, or IKA03N120H2 equivalent, key selection criteria include resonant circuit loss reduction, parallel switching capability, temperature-stable V_CE(sat) up to 150°C, tight parameter distribution, and JEDEC2 qualification for deflection applications.

Technical Context

This second-generation HighSpeed IGBT employs emitter-controlled technology enabling low conduction losses and soft, fast diode recovery-critical for zero-voltage transition (ZVT) operation in resonant horizontal deflection stages. Its 7nH internal emitter inductance and 8.6nC gate charge support precise timing control under high dv/dt conditions.

The device integrates a co-packaged HE diode with 52ns trr at 25°C and 112ns at 150°C, delivering controlled reverse recovery current (I_RRM = 9.3A typ. at 25°C) and di/dt of 723A/μs, minimizing voltage overshoot and EMI in flyback-type deflection circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE	1200V - supports full-line input rectified voltage in CRT TV deflection systems without derating
I_C	3A continuous - rated for sustained horizontal scan current in 50–100kHz resonant operation
E_off	0.15mJ at 25°C - enables low-loss switching in ZVT topologies with minimal heatsink requirement
V_CE(sat)	2.2V typ. at 25°C, 2.5V max. at 150°C - ensures stable conduction loss across operating temperature range
trr	52ns typ. at 25°C - provides soft, predictable diode recovery to suppress ringing and stress on snubber networks
R_thJC	4.3K/W - allows direct mounting to heatsink with verified thermal path for 29W power dissipation at TC=25°C
Q_g	8.6nC - enables fast, low-power gate drive with standard ±15V logic-level drivers

Pinout & Package

Package: PG-TO220-3-31 and PG-TO220-3-34 FullPAK - insulated case, through-hole mounting, thermally enhanced leadframe with isolated collector tab.

Pin/Terminal	Circuit Role	Design Meaning
Collector (Tab)	Main power output terminal	Electrically isolated metal tab; must be mounted to heatsink with insulating washer; carries full load current and switching voltage
Emitter	Power return and reference node	Low-inductance emitter connection; referenced to gate driver ground; shares common path with diode cathode
Gate	Control input	High-impedance MOS-driven terminal; requires ≤±20V drive; sensitive to noise due to 205pF C_iss

Key Features

Feature	Design Value
Integrated Emitter Controlled HE Diode	Soft, fast recovery (trr = 52ns) co-packaged with IGBT to eliminate external diode placement and parasitic inductance
Parallel Switching Capability	Tight parameter distribution (V_GE(th): 2.1–3.9V, V_CE(sat) variation <0.3V) enables reliable current sharing without external balancing resistors
Temperature-Stable Behavior	V_CE(sat) increases only 0.3V from 25°C to 150°C - maintains consistent conduction loss and thermal runaway immunity
ZVT-Optimized E_off	0.05mJ at 25°C in soft-switching condition - reduces turn-off loss by >65% vs. hard-switching mode for improved efficiency in resonant converters
JEDEC2 Qualification	Validated for TV horizontal deflection reliability including thermal cycling, humidity, and surge stress per target application requirements

Applications

TV Horizontal Deflection

Resonant Flyback Converters

Use Scenario: Driving horizontal output transformer in CRT television sets operating at 15.625kHz with quasi-resonant switching.

IC Role / Device Role / Timing Role: Main switch in line deflection yoke circuit; handles peak currents up to 8.2A and blocks 1200V during retrace.

Use Value: Soft diode recovery minimizes voltage spikes across yoke, eliminating need for complex snubbers and improving EMI compliance.

Use Scenario: Primary-side switch in high-efficiency resonant DC-DC converters for industrial auxiliary supplies.

IC Role / Device Role / Timing Role: Zero-voltage turn-on enabled by integrated diode's controlled reverse recovery, reducing switching loss and stress.

Use Value: 0.05mJ E_off in ZVT mode cuts total switching loss by 40% vs. standard IGBTs, enabling higher frequency operation at 100kHz.

Induction Heating Half-Bridge

UPS Inverter Stages

Use Scenario: Upper/lower leg switching in medium-power (1–3kW) induction cooktop half-bridge inverters.

IC Role / Device Role / Timing Role: Fast, matched pair for complementary PWM control; leverages parallel switching capability for current sharing.

Use Value: Tight V_CE(sat) distribution (<0.3V) ensures balanced conduction loss between legs, preventing thermal imbalance and premature failure.

Use Scenario: Output stage switch in online UPS systems requiring high-voltage blocking and low conduction loss.

IC Role / Device Role / Timing Role: Inverter bridge element handling 1200V DC bus and delivering clean sinusoidal output via PWM modulation.

Use Value: 150°C maximum junction temperature rating and 62K/W R_thJA support compact heatsink design in space-constrained rack-mount enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKP03N120H2	Same die, different package (PG-TO247-3-41); higher R_thJC (5.0K/W), no integrated diode	Requires external fast diode; better suited for forced-air cooled industrial inverters	Select when higher thermal margin is needed and discrete diode layout is acceptable
FGA25N120ANTD	1200V/25A; higher current rating, 1.8V V_CE(sat), no integrated diode, TO-3P package	Designed for motor drives; lacks soft-recovery diode and JEDEC2 deflection qualification	Choose only for non-deflection applications where higher current and lower V_CE(sat) outweigh diode integration needs

Compared with IKP03N120H2 and FGA25N120ANTD, IKA03N120H2 uniquely combines integrated soft-recovery diode, JEDEC2 qualification for TV deflection, and FullPAK thermal performance-making it irreplaceable in space- and EMI-constrained CRT horizontal output stages.

FAQ

What is the maximum gate-emitter voltage rating for IKA03N120H2?

The absolute maximum gate-emitter voltage is ±20V. Operation beyond this range risks permanent gate oxide damage. Recommended gate drive is +15V for turn-on and –5V to 0V for turn-off to ensure robust noise immunity and minimize Miller-induced false triggering during high dv/dt transitions.

Does IKA03N120H2 require an external freewheeling diode?

No. It integrates a soft, fast-recovery Emitter Controlled HE diode co-packaged in the same FullPAK housing. This eliminates PCB layout parasitics and ensures matched thermal and dynamic behavior between IGBT and diode-critical for ZVT operation in deflection circuits.

How does the thermal resistance differ between PG-TO220-3-31 and PG-TO220-3-34 packages?

Both variants share identical R_thJC = 4.3K/W for the IGBT and R_thJC(D) = 5.8K/W for the diode. The difference lies in leadframe geometry and creepage/clearance: PG-TO220-3-34 offers enhanced isolation (2500V_rms) and improved solder joint reliability for high-humidity environments, while PG-TO220-3-31 is optimized for cost-sensitive mass production.

Can IKA03N120H2 operate reliably at 150°C junction temperature?

Yes. It is fully specified and qualified for continuous operation up to T_j = 150°C, with V_CE(sat) = 2.5V max., E_off = 0.26mJ, and safe operating area validated per JEDEC2. Thermal design must maintain T_C ≤ 100°C to sustain 3A DC current, per Figure 4 in the datasheet.
