Product details

Overview

2SC6082 from onsemi is a low-saturation-voltage NPN bipolar power transistor in TO-220F-3SG package, rated for 50 V V_CEO, 15 A continuous collector current, and 200–560 DC current gain at 330 mA. It delivers 200 mV typical V_CE(sat) at 7.5 A/375 mA drive and supports high-speed switching in DC-DC converter primary-side drivers.

For engineers reviewing the 2SC6082 datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat) ≤ 400 mV at 7.5 A, f_T = 195 MHz, t_on/t_f ≤ 52 ns/37 ns, TO-220F-3SG thermal performance (23 W at T_c = 25°C), and JEITA SC-67 compliance.

Technical Context

The 2SC6082 employs onsemi's MBIT process to achieve low saturation voltage and high current handling while maintaining fast switching. Its structure supports robust operation under pulsed conditions (I_CP = 20 A, PW ≤ 10 μs) and features tight parameter distribution across temperature (–25°C to +75°C) for stable gain and saturation behavior.

Designed for hard-switched power stages, it exhibits low output capacitance (C_ob = 85 pF at V_CB = 10 V), high f_T, and short storage time (t_stg = 560 ns), enabling efficient operation in 100–500 kHz switching regulators without requiring complex snubbing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum safe collector-emitter voltage with open base; defines upper limit for flyback/snubber clamp design.
I_C (continuous)	15 A - Continuous collector current rating at T_c = 25°C; determines heatsink sizing for sustained conduction.
V_CE(sat)	200–400 mV @ I_C = 7.5 A, I_B = 375 mA - Low saturation loss enables >95% efficiency in 12–48 V input switchers.
f_T	195 MHz - Gain-bandwidth product confirming suitability for sub-500 kHz PWM control with margin.
t_on/t_f	52 ns / 37 ns - Fast turn-on and fall times reduce switching losses and EMI generation in hard-switched topologies.
P_C @ T_c = 25°C	23 W - Package-limited dissipation; enables compact thermal design when mounted on ≥10 cm² copper area.
h_FE	200–560 @ I_C = 330 mA - Wide DC gain range supports stable biasing across production lots and temperature.

Pinout & Package

Package: TO-220F-3SG (JEITA SC-67), insulated flange, 3-terminal through-hole package with 1.8 g mass and 10.16 mm width. Flange is electrically isolated from collector.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal; requires ≥375 mA peak drive for full saturation at 7.5 A load.
2	Collector	High-current output node; connected to flange via internal isolation; must be thermally coupled to heatsink.
3	Emitter	Power return path; low-inductance layout critical to minimize V_BE disturbance during switching.

Key Features

Feature	Design Value
MBIT process technology	Enables simultaneous optimization of V_CE(sat), f_T, and ruggedness-no trade-off between conduction loss and speed.
Low V_CE(sat)	200 mV typical at 7.5 A reduces conduction loss by >40% vs. standard bipolar transistors with comparable I_C.
High I_C capability	15 A continuous rating allows single-device use in 200–300 W offline SMPS primary switches without paralleling.
Fast switching	52 ns t_on and 37 ns t_f support clean edge transitions up to 300 kHz, easing EMI filter design.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC5415	V_CEO = 50 V, I_C = 10 A, V_CE(sat) = 300 mV @ 5 A - lower current and higher saturation voltage.	Suitable for ≤150 W converters; not recommended for 7.5 A continuous loads.	Select 2SC5415 only if board space or cost constraints preclude TO-220F-3SG footprint.
MJD127G	V_CEO = 100 V, I_C = 10 A, V_CE(sat) = 1.2 V @ 5 A - higher voltage rating but significantly higher saturation loss.	Better for 100 V bus applications; unsuitable where low-loss 48 V switching is required.	Choose MJD127G only when system overvoltage margin exceeds 80 V and thermal budget allows >6 W conduction loss.

Compared with 2SC6082, 2SC5415 offers smaller footprint but sacrifices 33% current capacity and 50% conduction efficiency; MJD127G trades 2.4× higher V_CE(sat) for doubled voltage rating-neither is pin-compatible, and both require PCB layout revision.

FAQ

What is the maximum continuous collector current rating for the 2SC6082?

The 2SC6082 is rated for 15 A continuous collector current at case temperature T_c = 25°C. Derating is required above this temperature per the PC–T_c curve in the datasheet; at T_c = 100°C, maximum I_C drops to approximately 8.5 A. This rating assumes proper heatsinking and is validated under DC operation with no pulse duty cycle limitations.

Does the 2SC6082 have an insulated package, and how does that affect mounting?

Yes, the 2SC6082 uses the TO-220F-3SG package with an electrically insulated flange. This allows direct mechanical mounting to a common heatsink without requiring insulating washers or pads, simplifying thermal design and reducing thermal resistance. The insulation withstands ≥2500 V RMS, supporting safe operation in grounded-chassis industrial systems.

What is the typical V_CE(sat) of the 2SC6082 under standard switching conditions?

The typical V_CE(sat) of the 2SC6082 is 200 mV at I_C = 7.5 A and I_B = 375 mA, with a maximum of 400 mV under the same conditions. This value is measured at T_a = 25°C and reflects the device's optimized MBIT process for low conduction loss in hard-switched power stages.

Can the 2SC6082 be used in avalanche mode for snubberless operation?

No, the 2SC6082 is not rated or characterized for repetitive avalanche operation. Its absolute maximum ratings specify V_CEO = 50 V and V_CES = 60 V, but the datasheet provides no SOA curves or energy ratings for avalanche. For snubberless designs, a specifically avalanche-rated transistor such as the 2SC5027 should be selected instead of the 2SC6082.

Is the 2SC6082 RoHS compliant and lead-free?

Yes, the 2SC6082-1E variant is Pb-free and RoHS compliant, as confirmed by the "Pb Free" marking in the Ordering Information section and the "RoHS Compliant" designation in onsemi's official packaging documentation (ENA0279B). All units supplied by Aetrix Electronics meet EU Directive 2011/65/EU requirements without exemptions.
