Product details

Overview

2N6292 from onsemi is an NPN silicon power transistor in a TO-220 package, rated for 70 V_CEO, 7 A continuous collector current, and 40 W total power dissipation at T_C = 25°C. It delivers high DC current gain (h_FE ≥ 30 at I_C = 2.0 A), 4.0 MHz f_T, and supports general-purpose amplifier and switching applications in industrial power supplies and motor controls.

For engineers reviewing the 2N6292 datasheet, pinout, applications, or equivalent options, key selection criteria include its 70 V_CEO rating, 40 W thermal capability with R_JC = 3.125°C/W, TO-220 mechanical compatibility, and verified performance under pulse and DC switching conditions per JEDEC standards.

Technical Context

The 2N6292 operates as a medium-power NPN bipolar junction transistor optimized for linear amplification and hard-switching duty. Its electrical behavior is defined by V_CEO = 70 V, I_C = 7.0 A, and V_CE(sat) ≤ 3.5 V at I_C = 7.0 A / I_B = 3.0 A - confirming robust saturation performance under high-current drive.

Thermal design is constrained by R_JC = 3.125°C/W and a maximum junction temperature of +150°C. Safe operating area (SOA) curves specify secondary breakdown limits up to 100 V and 7 A for single-pulse operation, with derating required above 25°C case temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	70 Vdc - maximum collector-emitter voltage before breakdown under open-base conditions
I_C (continuous)	7.0 Adc - usable DC collector current with adequate heatsinking at T_C ≤ 25°C
P_D @ T_C = 25°C	40 W - total power dissipation limit requiring thermal interface and heatsink design
h_FE	≥30 - minimum DC current gain at I_C = 2.0 A, V_CE = 4.0 V, enabling predictable base drive sizing
f_T	4.0 MHz - current gain-bandwidth product indicating usable frequency range for small-signal amplification
R_JC	3.125°C/W - junction-to-case thermal resistance defining minimum heatsink requirement for thermal management

Pinout & Package

2N6292 uses the standard TO-220 package (Case 221A, Style 1), with metal tab electrically connected to collector. Mounting requires insulated hardware or thermal pad due to collector-isolation constraints.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal; requires current-limited drive (I_B ≤ 3.0 Adc) to achieve full saturation
2 & 4	Collector	Main high-current output terminal; electrically tied to metal tab - must be isolated from chassis unless common-collector configuration is intended
3	Emitter	Reference/return path for collector current; low-impedance connection critical for stable bias and switching transitions

Key Features

Feature	Design Value
High DC current gain	h_FE ≥ 30 at I_C = 2.0 A ensures reliable base drive margin in linear and switching designs
High f_T	4.0 MHz bandwidth supports audio-frequency amplification and moderate-speed switching
TO-220 compact package	Standardized footprint enables drop-in replacement and heatsink compatibility across legacy power BJT designs
Pb-free & RoHS compliant	G-suffix marking confirms compliance with environmental regulations without compromising thermal or electrical performance

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJE13009	Higher V_CEO (400 V), lower h_FE (min 8), TO-220 package	Better suited for flyback SMPS primary switches; less ideal for linear regulation due to gain variability	Select when high-voltage isolation is required over precise gain control
2N3055G	Lower V_CEO (60 V), same I_C (7 A), higher R_JC (3.5°C/W), TO-3 package	Larger mechanical footprint and inferior thermal resistance; legacy design with limited f_T (1 MHz)	Choose only for backward-compatible TO-3 socket replacements where board space permits

Compared with MJE13009 and 2N3055G, the 2N6292 offers optimal balance of voltage rating, gain consistency, and thermal efficiency in TO-220 form factor - making it preferred for mid-voltage linear and switching applications where SOA integrity and predictable h_FE are critical.

FAQ

What is the maximum collector-emitter voltage rating for the 2N6292?

The 2N6292 has a maximum collector-emitter voltage (V_CEO) rating of 70 Vdc under open-base conditions, as specified in the onsemi datasheet. This rating defines the absolute upper limit for voltage applied between collector and emitter before risk of avalanche breakdown. Operation near this limit requires verification of SOA boundaries and thermal margin, especially under transient or pulsed conditions.

Is the 2N6292 suitable for linear amplifier applications?

Yes, the 2N6292 is explicitly designed for general-purpose amplifier applications per its datasheet. With h_FE ≥ 30 at I_C = 2.0 A and f_T = 4.0 MHz, it supports audio-frequency linear amplification. Its SOA curve and thermal characteristics (R_JC = 3.125°C/W) enable stable operation in Class-A or Class-AB output stages when properly heatsinked and biased.

Does the 2N6292 have a Pb-free and RoHS-compliant package?

Yes, the 2N6292G variant is Pb-free and RoHS compliant, as confirmed by onsemi's marking convention and datasheet footnote. The "G" suffix denotes the Pb-free TO-220 package, and the device meets EU RoHS Directive 2011/65/EU requirements without performance trade-offs in electrical or thermal specifications.

What is the thermal resistance from junction to case for the 2N6292?

The 2N6292 has a maximum thermal resistance from junction to case (R_JC) of 3.125°C/W, measured under standard test conditions. This value is critical for heatsink sizing: for example, at 20 W dissipation and 25°C case temperature, junction temperature will rise by 62.5°C - requiring a heatsink that maintains T_C ≤ 87.5°C to stay within the +150°C absolute maximum.

Can the 2N6292 replace the 2N3055 in existing designs?

The 2N6292 is not a direct replacement for the 2N3055 due to differences in package (TO-220 vs. TO-3), thermal resistance (3.125°C/W vs. 3.5°C/W), and V_CEO (70 V vs. 60 V). While both handle 7 A, the 2N6292 offers better voltage margin and smaller footprint but requires PCB layout revision. Use only after validating SOA, drive requirements, and thermal interface in the target application.
