Product details

Overview

2SC6097-E from onsemi is an NPN bipolar junction transistor optimized for high-current switching in power electronics, featuring V_CEO = 60 V, I_C = 3 A continuous, V_CE(sat) ≤ 150 mV at I_C = 1 A / I_B = 50 mA, f_T = 390 MHz, and housed in SC-64 (TO-251) package. It serves as a main switch in DC/DC converters and motor drivers where low saturation loss and thermal robustness are critical.

For engineers reviewing the 2SC6097-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat) performance at 1 A, h_FE range of 300–600 at 100 mA, TO-251 thermal dissipation capability (15 W at T_C = 25°C), and confirmed suitability for relay and lamp driver topologies per onsemi's published test circuits.

Technical Context

This NPN transistor employs onsemi's FBET and MBIT process to achieve low V_CE(sat) and high-speed switching (t_on = 35 ns, t_f = 24 ns). Its breakdown ratings-V_(BR)CBO = 100 V, V_(BR)CEO = 60 V, and V_(BR)EBO = 6.5 V-define safe operating limits under open-base and open-emitter conditions.

The device supports pulsed collector current up to 5 A (I_CP) and operates across −55°C to +150°C junction temperature range. Its Cob = 18 pF at V_CB = 10 V enables stable high-frequency gain behavior, validated in f_T vs. I_C curves up to 500 mA.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum collector-emitter voltage with base open; sets upper limit for DC/DC flyback and motor drive bus voltage compatibility.
I_C (continuous)	3 A - Continuous collector current rating; defines steady-state load-handling capacity in relay and lamp drivers.
V_CE(sat) @ 1 A / 50 mA	≤150 mV - Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle switching applications.
h_FE @ 2 V, 100 mA	300–600 - DC current gain range determines required base drive strength and impacts gate driver sizing in discrete BJT stages.
f_T	390 MHz - Gain-bandwidth product confirms suitability for >100 kHz switching frequencies in SMPS designs.
P_C @ T_C = 25°C	15 W - Case-referenced power dissipation enables high-power pulse operation without heatsink in short-duration loads.
C_ob	18 pF @ 10 V - Output capacitance affects turn-off energy and EMI in hard-switched topologies.

Pinout & Package

2SC6097-E is packaged in SC-64 (TO-251), a surface-mount variant of TO-251 with gull-wing leads and exposed drain pad thermally connected to collector. The package provides enhanced thermal transfer versus TO-92 and supports automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or low-side return path; must handle full load current and support fast discharge during turn-off.
2 (Base)	Control input	Receives current-limited drive signal; requires ≥50 mA for full saturation at 1 A collector load per datasheet test condition.
3 (Collector)	High-side current source	Connected to positive rail or inductive load; electrically and thermally tied to exposed pad for heat dissipation.

Key Features

Feature	Design Value
Low V_CE(sat)	100–150 mV at I_C = 1 A ensures <150 mW conduction loss, reducing thermal stress in compact motor driver PCBs.
High-speed switching	t_on/t_f = 35 ns/24 ns enables clean square-wave operation up to 2 MHz in resonant or Class-E topologies.
Large current capacity	3 A continuous / 5 A pulsed rating supports direct driving of 24 V solenoids and small BLDC phase legs without external buffers.
High allowable power dissipation	15 W at T_C = 25°C allows sustained operation at >2 A with minimal heatsinking in ambient temperatures ≤50°C.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD127G	V_CEO = 100 V, I_C = 2 A, V_CE(sat) = 1.5 V @ 1 A - higher saturation voltage, lower current rating	Less suitable for 1 A+ continuous loads due to higher conduction loss and thermal rise	Select when higher V_CEO margin is prioritized over efficiency at 1–2 A loads
2SD2656	h_FE = 120–240 @ 1 A, f_T = 100 MHz - lower gain, slower switching	Requires larger base drive and exhibits longer storage time (t_stg = 1.2 μs vs. 680 ns), limiting max PWM frequency	Prefer for cost-sensitive, low-frequency (<50 kHz) linear or quasi-resonant applications

Compared with MJD127G and 2SD2656, the 2SC6097-E delivers superior efficiency at 1–3 A loads due to its sub-150 mV V_CE(sat), higher f_T, and tighter h_FE distribution-making it optimal for space-constrained, thermally demanding DC/DC and motor control designs.

FAQ

What is the maximum continuous collector current rating for the 2SC6097-E?

The 2SC6097-E has a maximum continuous collector current (I_C) rating of 3 A at T_A = 25°C. This rating assumes proper PCB copper area and thermal management; derating applies above 25°C ambient, with full 3 A operation supported up to T_C ≈ 70°C per the PC vs. TC curve in the datasheet. At 50°C ambient with 1-in² 2-oz copper, typical usable I_C remains ≥2.5 A.

Does the 2SC6097-E support pulsed operation beyond its DC current rating?

Yes, the 2SC6097-E supports pulsed collector current (I_CP) up to 5 A, specified under conditions of <10 μs pulse width and 1% duty cycle. This capability is validated in the Safe Operating Area (SOA) plots (Figures 9–10), confirming reliability for inrush current handling in lamp and relay drivers without secondary protection circuitry.

What package type is used for the 2SC6097-E, and how does it impact thermal performance?

The 2SC6097-E uses the SC-64 (TO-251) package, which features an exposed collector pad for direct thermal coupling to the PCB. This construction achieves 15 W power dissipation at T_C = 25°C-over 18× higher than TO-92 alternatives-and enables efficient heat spreading across internal copper layers, critical for motor driver and converter applications with limited heatsink space.

How does the 2SC6097-E's V_CE(sat) compare to standard NPN transistors in similar packages?

The 2SC6097-E achieves V_CE(sat) ≤150 mV at I_C = 1 A / I_B = 50 mA-approximately 3–5× lower than conventional NPN transistors like the MMBT4401 (V_CE(sat) ≈ 750 mV). This reduction directly lowers conduction losses and junction temperature rise, extending reliability in thermally constrained 24 V industrial control modules.

Is the 2SC6097-E suitable for high-frequency switching applications such as Class-D audio or RF amplifiers?

The 2SC6097-E is rated for f_T = 390 MHz and exhibits t_f = 24 ns, making it suitable for switching applications up to ~2 MHz, including high-frequency DC/DC converters and PWM motor control. However, it is not characterized or recommended for RF amplifier use above 30 MHz due to lack of S-parameter data, gain flatness validation, or harmonic distortion specifications in the datasheet.
