Product details

Overview

IPP034N03LGHKSA1 from Infineon Technologies is an N-channel logic-level power MOSFET in PG-TO220-3-1 package, rated for 30 V V_DS, 3.4 mΩ R_DS(on) at V_GS = 10 V, 80 A continuous drain current, and avalanche-rated operation-designed for high-efficiency DC/DC converters and SMPS primary-side switching stages in telecom and server power supplies.

For engineers reviewing the IPP034N03LGHKSA1 datasheet, IPP034N03LGHKSA1 pinout, IPP034N03LGHKSA1 application, or IPP034N03LGHKSA1 equivalent, key selection criteria include its low gate charge × R_DS(on) figure of merit (FOM), 25 nC total gate charge at 10 V, 4.5 V logic-level drive compatibility, and validated avalanche energy rating of 70 mJ for robust transient handling in hard-switched topologies.

Technical Context

This MOSFET employs Infineon's OptiMOS™ 3 technology, optimized for high-frequency switching with minimized conduction and switching losses. Its dynamic parameters include C_iss = 4000–5300 pF, C_oss = 1400–1900 pF, and Q_g = 25 nC (V_DD = 15 V, I_D = 30 A), enabling efficient operation in synchronous rectification and half-bridge configurations up to 1 MHz.

The device features a fully characterized reverse diode with V_SD = 0.83–1.1 V at I_F = 30 A and Q_rr = 20 nC under specified dI/dt conditions, supporting ZVS-assisted designs and reducing body-diode conduction loss in buck-derived topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	30 V - supports 24 V input rail systems with margin for voltage spikes and ripple
R_DS(on) max	3.4 mΩ at V_GS = 10 V - enables <1 W conduction loss at 80 A, critical for high-current POL converters
I_D Continuous	80 A at T_C = 25 °C - requires heatsink with R_thJC ≤ 1.6 K/W for thermal compliance
Q_g Total	25 nC at V_GS = 0–10 V - determines gate driver current requirement (~2.5 A peak for 10 ns rise time)
E_AS	70 mJ single-pulse avalanche energy - ensures reliability during inductive turn-off transients without external snubbers
V_GS(th)	1.0–2.2 V - guarantees full enhancement with standard 3.3 V or 5 V logic-level controllers
Q_gd	5.6 nC - directly impacts Miller-induced switching delay and dv/dt immunity in high-side configurations

Pinout & Package

IPP034N03LGHKSA1 uses the PG-TO220-3-1 package: through-hole, isolated drain tab, 3-pin configuration with standard TO-220 footprint and mechanical mounting hole. Thermal resistance junction-to-case is 1.6 K/W, measured from drain tab to source pin.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal (S)	Reference node for gate drive; connects to low-side return path and PCB ground plane
Pin 2 (Gate)	Control terminal (G)	High-impedance input requiring low-inductance gate loop; drives channel conduction via V_GS
Pin 3 (Drain)	Power output terminal (D)	Exposed metal tab electrically connected to drain; serves as primary heat dissipation surface and high-current path

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS ≥ 4.5 V, compatible with microcontroller GPIOs and low-voltage PWM controllers
Avalanche-rated construction	Guaranteed single-pulse E_AS = 70 mJ enables reliable operation in non-clamped inductive switching without derating
Low Q_g × R_DS(on) FOM	~85 mΩ·nC - balances switching speed and conduction loss for optimal efficiency in 300–1000 kHz SMPS
RoHS & halogen-free	Pb-free plating and IEC61249-2-21 compliant materials meet industrial and telecom environmental requirements

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB034N03LG	SMD version in PG-TO263-3 package; identical electrical specs but lower R_thJA (40 K/W vs 62 K/W on minimal PCB)	Better suited for space-constrained, high-density PCB layouts with forced-air cooling	Select when board area is limited and thermal interface to heatsink is via soldered copper pad rather than mechanical clamp
STL110N3LLH6	30 V, 110 A, R_DS(on) = 2.8 mΩ, Q_g = 34 nC - higher current rating but larger gate drive demand	Preferred in higher-power (>4 kW) PFC or inverters where peak current exceeds 80 A	Choose only if system requires >10 A additional headroom and can accommodate increased gate drive power and layout inductance

Compared with IPB034N03LG, IPP034N03LGHKSA1 offers superior mechanical mounting rigidity and higher pulse current tolerance due to TO-220 leadframe; versus STL110N3LLH6, it delivers lower gate drive burden and tighter V_GS(th) distribution for stable multi-phase current sharing.

FAQ

What is the maximum safe operating temperature for IPP034N03LGHKSA1?

The junction temperature must not exceed 175 °C under any operating condition. With R_thJC = 1.6 K/W and 94 W power dissipation at T_C = 25 °C, thermal design must ensure case temperature remains ≤ 75 °C at full 80 A load to maintain 100 °C safety margin. Derating curves in the datasheet define linear I_D reduction above 25 °C case temperature.

Can IPP034N03LGHKSA1 be used in synchronous rectification?

Yes-it is qualified for synchronous rectifier use with its low R_DS(on) and characterized reverse diode. The 0.83–1.1 V V_SD and 20 nC Q_rr enable efficient body-diode conduction during dead-time, while logic-level gate drive allows direct control by standard SR controllers like UCC24612 without level-shifting.

Is IPP034N03LGHKSA1 pin-compatible with earlier OptiMOS generations?

No-while the PG-TO220-3-1 footprint is mechanically identical, electrical characteristics differ significantly: OptiMOS 2 devices have higher R_DS(on) and Q_g, and lack the same avalanche energy rating. Direct replacement requires validation of gate drive timing, thermal margins, and transient stress in the target circuit.

Does this MOSFET require a gate resistor for stability?

Yes-a series gate resistor (typically 2.2–10 Ω) is required to dampen parasitic oscillation and control dv/dt during switching. The 1.6 Ω internal gate resistance and 5.6 nC Q_gd make it susceptible to Miller-induced shoot-through in high-dv/dt environments; resistor value must be selected based on driver capability and layout parasitics per Figure 16 in the datasheet.
