Product details

Overview

STGF35HF60W from STMicroelectronics is a 35 A, 600 V ultrafast IGBT in TO-220FP package, designed for high-frequency switching above 100 kHz. It features minimal tail current, low conduction losses (V_CE(sat) = 2.0–2.5 V at 20 A, 25 °C), improved E_off stability over temperature, and R_thj-case = 3.1 °C/W - enabling use in compact welding inverters and PFC stages.

For engineers reviewing the STGF35HF60W datasheet, STGF35HF60W pinout, STGF35HF60W application, or STGF35HF60W equivalent, key selection criteria include gate charge (Q_g = 140 nC), switching energy at 125 °C (E_off = 350 µJ), thermal resistance, and TO-220FP mounting compatibility with standard heatsinks.

Technical Context

This IGBT employs ST's planar technology to tighten E_off variation across temperature (±15% from −50 °C to 125 °C) and reduce tail current decay time (t_f = 40 ns typ. at 25 °C). Its co-pack diode–free design requires external fast recovery diodes in inductive switching circuits.

It operates with ±20 V gate-emitter voltage rating and supports 150 A pulsed collector current under RBSOA-limited conditions. The device targets hard-switched topologies where V_CE(sat) stability (1.65 V at 20 A, 125 °C) and low C_res (50 pF) reduce dynamic losses at high dV/dt.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	600 V - Withstands DC bus voltages up to 400 V in PFC and welding inverters with 50% safety margin.
I_C (T_C = 100 °C)	12 A - Continuous output current capability at heatsink temperature of 100 °C, defining real-world thermal derating.
V_CE(sat)	2.0–2.5 V @ 20 A, 25 °C - Directly determines conduction loss (P_cond ≈ 40–50 W at full load), critical for efficiency in high-duty-cycle converters.
E_off	185 µJ @ 400 V, 20 A, 25 °C - Quantifies turn-off energy dissipation; increases to 350 µJ at 125 °C, guiding snubber and heatsink sizing.
Q_g	140 nC - Total gate charge required for full enhancement; sets minimum gate driver peak current (≥14 A for 10 ns rise time).
R_thj-case	3.1 °C/W - Junction-to-case thermal resistance defines maximum allowable case temperature for 150 °C T_j operation (ΔT = 312 W × 3.1 = 96.7 °C rise).
C_res	50 pF @ 25 V - Reverse transfer capacitance governs Miller effect; limits achievable dV/dt immunity and gate drive robustness.

Pinout & Package

STGF35HF60W uses the TO-220FP (Full-Pak) package: insulated plastic case with metal tab electrically connected to collector, enabling direct heatsink mounting without insulating washers. Pin 1 = Gate, Pin 2 = Collector (tab), Pin 3 = Emitter.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; accepts ±20 V gate-emitter voltage; requires 140 nC total charge for full turn-on.
Pin 2	Collector (Tab)	Main power input; electrically tied to metal tab; must be mounted to heatsink with thermal interface but no electrical isolation.
Pin 3	Emitter	Power return path and reference for gate drive; carries full load current and must be routed with low-inductance layout.

Key Features

Feature	Design Value
Ultrafast switching with minimal tail current	t_f = 40 ns (25 °C), reducing turn-off losses and enabling >100 kHz operation in resonant and hard-switched converters.
Stable E_off vs. temperature	E_off increases only 89% from 25 °C to 125 °C (185 → 350 µJ), easing thermal design versus legacy IGBTs with >2× increase.
Low V_CE(sat) at high junction temperature	1.65 V @ 20 A, 125 °C - Maintains conduction efficiency under thermal stress, critical for sustained welder arc stability.
TO-220FP insulated package	Integrated isolation eliminates need for mica washers; simplifies mechanical assembly and improves thermal contact reliability.
High gate threshold voltage	V_GE(th) = 3.75–5.75 V - Reduces risk of spurious turn-on from noise or crosstalk in high-dV/dt environments like welding arcs.

Applications

Welding Inverters

High-Frequency PFC

Use Scenario: Primary-side switching in 20–50 kHz IGBT-based inverter welders delivering 150–300 A DC output.

IC Role / Device Role / Timing Role: Main power switch controlling transformer primary current; handles repetitive 150 A pulses with <100 ns switching transitions.

Use Value: Minimal tail current and stable E_off ensure consistent arc initiation and reduced thermal runaway risk during extended duty cycles.

Use Scenario: Boost switch in active front-end PFC stages for industrial UPS and motor drives operating at 60–120 kHz.

IC Role / Device Role / Timing Role: High-speed unidirectional switch synchronizing with AC line zero-crossings; commutates 20–35 A RMS current.

Use Value: Low C_res (50 pF) and fast t_f (40 ns) minimize switching loss and enable efficient operation above 100 kHz without excessive gate drive power.

Induction Heating

UPS Inverter Stages

Use Scenario: Half-bridge switching in 20–80 kHz solid-state induction heaters for metal hardening and brazing.

IC Role / Device Role / Timing Role: High-current, high-dV/dt switch in resonant tank circuits; subjected to rapid voltage reversal and high di/dt.

Use Value: 600 V V_CES rating and 2500 V isolation withstand support reliable operation under 1.5× nominal bus voltage transients.

Use Scenario: Output H-bridge stage in online double-conversion UPS systems delivering clean 50/60 Hz sine wave to critical loads.

IC Role / Device Role / Timing Role: Low-loss switching element in PWM-controlled inverter leg; conducts up to 35 A continuous with tight thermal control.

Use Value: R_thj-case = 3.1 °C/W allows direct heatsink mounting and maintains T_j < 130 °C at full rated load, ensuring long-term reliability.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN35N60B3	Higher V_CE(sat) (2.7 V @ 20 A), higher Q_g (220 nC), TO-247 package with non-insulated tab.	Requires electrical isolation hardware; less suitable for space-constrained TO-220FP footprints.	Prefer when higher surge current rating (I_CP = 210 A) outweighs gate drive complexity.
Infineon IKP35N60T	Lower E_off (140 µJ @ 25 °C) but significantly higher tail current (t_f = 120 ns); TO-220FP with insulated tab.	Better efficiency at light load; worse thermal performance under sustained high-current switching.	Prefer for soft-switched topologies where tail current is mitigated by ZVS, not hard-switched welders.

Compared with IXGN35N60B3 and IKP35N60T, STGF35HF60W delivers optimal balance of low tail current, stable high-temperature E_off, and TO-220FP insulation - making it uniquely suited for thermally demanding, high-dV/dt welding and PFC designs where layout simplicity and thermal predictability are critical.

FAQ

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

With Q_g = 140 nC and typical gate drive voltage of 15 V, a 10 Ω gate resistor yields ~14 A peak current and ~30 ns turn-on delay - matching ST's test conditions. Values above 22 Ω increase switching losses significantly; below 5 Ω risks gate oscillation without proper layout. Thermal derating applies above 100 kHz.

Does STGF35HF60W include an integrated freewheeling diode?

No. STGF35HF60W is a standalone IGBT without co-packaged diode. External ultrafast recovery diodes (e.g., STTH30L06D) must be used in inductive load circuits to handle reverse recovery current and prevent destructive voltage spikes during turn-off.

Can this IGBT be used in 650 V DC bus applications?

No. Its absolute maximum V_CES is 600 V with no safety margin for transients. For 650 V DC bus systems, ST recommends STGW40H65DFB (650 V, TO-247) or similar rated devices. Operating STGF35HF60W above 600 V risks immediate avalanche failure.

What is the meaning of the "W" suffix in STGF35HF60W?

The "W" denotes ST's high-frequency subset: devices optimized for operation above 100 kHz via tighter E_off variation, reduced tail current, and enhanced thermal stability - distinguishing them from standard HF60 variants intended for ≤50 kHz applications.
