Product details
Overview
IGA03N120H2XKSA1 from Infineon is a 1200V, 3A high-speed IGBT in PG-TO220-3-31 FullPAK package, optimized for horizontal line deflection in CRT TVs. It delivers 0.15mJ turn-off energy at Tj=25°C, 2.2V VCE(sat) at 3A/25°C, and operates up to 150°C junction temperature with ±20V gate rating.
For engineers reviewing the IGA03N120H2XKSA1 datasheet, IGA03N120H2XKSA1 pinout, IGA03N120H2XKSA1 application, or IGA03N120H2XKSA1 equivalent, key selection criteria include resonant circuit loss reduction, parallel switching capability, tight parameter distribution, Eoff optimization at 3A, and JEDEC-qualified reliability for TV deflection systems.
Technical Context
This second-generation HighSpeed IGBT uses field-stop trench technology to achieve low conduction and switching losses simultaneously. Its 7nH internal emitter inductance and 205pF input capacitance support fast, stable switching in resonant flyback and line output stages.
The device features temperature-stable VGE(th) (2.1–3.9V) and VCE(sat) (2.2–2.8V across –40°C to 150°C), enabling robust operation in thermally demanding deflection circuits without active gate drive compensation.
Key Specifications

|---|---|
| VCE | 1200V - supports full-line voltage swing in 110–240VAC CRT TV horizontal deflection circuits |
| IC | 3A continuous - rated for sustained current in 15–30kHz resonant line scan operation |
| Eoff | 0.15mJ at 25°C - enables low-loss zero-voltage transition (ZVT) switching in soft-switched deflection stages |
| RthJC | 4.3K/W - allows 29W power dissipation at 25°C case temperature, critical for compact heatsink designs |
| VCE(sat) | 2.2V at 3A/25°C - minimizes conduction loss and thermal stress during peak current pulses |
| td(off) | 281ns typical - ensures precise timing control in high-frequency line scanning with minimal jitter |
| Ciss | 205pF - balances gate drive strength and noise immunity in high-dv/dt deflection environments |

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, identical electrical specs, but in PG-TO247-3-1 package with higher RthJC (0.5K/W vs. 4.3K/W) | Requires larger heatsink; better suited for industrial modules than space-constrained TV chassis | Select when board-level thermal management allows TO-247 mounting and higher peak power is needed |
| FGA25N120ANTD | 1200V/25A, higher current rating, 1.8V VCE(sat), but Eoff = 0.45mJ - 3× higher than IGA03N120H2XKSA1 | Designed for motor drives, not optimized for resonant TV deflection; slower switching limits ZVT usability | Choose only if system requires >10A current capability and can tolerate higher switching loss and larger footprint |
Compared with IKP03N120H2 and FGA25N120ANTD, IGA03N120H2XKSA1 offers superior thermal integration in compact TV designs, lowest Eoff for ZVT operation, and tighter parameter spread-making it uniquely suited for cost-sensitive, high-volume horizontal deflection applications where size, efficiency, and consistency are critical.

FAQ
What is the maximum safe operating frequency for IGA03N120H2XKSA1 in TV horizontal deflection?
The device is characterized for stable operation up to 32kHz (triangular collector peak current test condition), with typical use at 15.625kHz in CRT TVs. At 3A and 800V, Figure 1 shows usable collector current up to 25kHz at TC=100°C, confirming design margin for standard broadcast line rates.
Does IGA03N120H2XKSA1 include an integrated freewheeling diode?
No. The IGA03N120H2XKSA1 is a standalone IGBT without an integrated body diode. External fast-recovery diodes (e.g., IDH08SG60C) must be used in anti-parallel configuration for inductive load commutation, as confirmed by the "diode reverse recovery" note in switching energy test conditions.
Can IGA03N120H2XKSA1 be paralleled with other units without external ballasting?
Yes. Its tight parameter distribution (±5% VCE(sat), ±10% Eoff) and temperature-stable characteristics enable direct paralleling in TV deflection circuits. Infineon explicitly states "parallel switching capability" as a core feature in the datasheet introduction and validates this via JEDEC qualification.
What is the isolation voltage rating and how is it implemented?
The device has a 2500VRMS isolation voltage (Visol) between collector and package tab, achieved via reinforced insulation in the PG-TO220-3-31 FullPAK mold compound. This allows direct mounting to grounded heatsinks without additional insulating hardware in TV chassis applications.
