Product details

Overview

2N6107G from onsemi is a PNP silicon power transistor in 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 DC current gain (h_FE) ≥30 at I_C = 7.0 A, V_CE = 4.0 V, and supports general-purpose switching and linear amplifier applications in industrial power supplies and motor control circuits.

For engineers reviewing the 2N6107G datasheet, pinout, applications, or equivalent options, key selection criteria include its 70 V_CEO rating, 3.125°C/W junction-to-case thermal resistance, PNP polarity with base-emitter voltage ≤3.0 V at I_C = 7.0 A, and Pb-free TO-220 packaging compliant with RoHS.

Technical Context

The 2N6107G operates as a medium-power PNP bipolar junction transistor optimized for robust switching and analog amplification. Its safe operating area (SOA) is defined up to 7 A and 70 V under single-pulse conditions at T_C = 25°C, with secondary breakdown and thermal limits explicitly characterized in Figure 5 of the datasheet.

It exhibits f_T = 10 MHz at I_C = 500 mA, V_CE = 4.0 V, and has C_ob = 250 pF at V_CB = 10 V, supporting moderate-frequency switching. The device uses standard B-E-C terminal assignment in TO-220 case 221A style 1, with collector internally connected to the metal tab for heatsinking.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	70 Vdc - Maximum collector-emitter voltage before breakdown under open-base conditions; defines upper voltage limit in switching topologies.
I_C (continuous)	7.0 Adc - Continuous collector current rating at T_C = 25°C; determines maximum steady-state load drive capability.
P_D	40 W - Total power dissipation at T_C = 25°C; requires heatsink design accounting for 3.125°C/W R_JC.
h_FE	≥30 - DC current gain at I_C = 7.0 A, V_CE = 4.0 V; sets minimum base drive current required for saturation.
V_CE(sat)	≤3.5 Vdc - Collector-emitter saturation voltage at I_C = 7.0 A, I_B = 3.0 A; directly impacts conduction loss in switch-mode operation.
f_T	10 MHz - Current gain-bandwidth product at I_C = 500 mA; indicates usable frequency range for small-signal amplification.

Pinout & Package

2N6107G uses the TO-220 package (Case 221A, Style 1), with the metal tab electrically connected to the collector terminal and designed for mechanical mounting and thermal conduction to a heatsink.

Pin/Terminal	Circuit Role	Design Meaning
1 (Leftmost, when face-up, tab down)	Base	Control electrode; requires ≥3.0 A peak base current for full saturation at 7 A collector load.
2 & 4 (Tab and center pin)	Collector	Main high-current output terminal; internally bonded to metal tab for low-inductance, high-power thermal path.
3 (Rightmost)	Emitter	Current return path; reverse-biased V_EB rating of 5.0 Vdc defines maximum allowable emitter-base reverse voltage.

Key Features

Feature	Design Value
High V_CEO rating	70 Vdc enables use in 48 V and 60 V industrial bus systems without derating.
Robust SOA	Defined active-region SOA up to 7 A/70 V (single pulse, T_C = 25°C) supports reliable hard-switching in relay drivers and PWM stages.
Thermal performance	R_JC = 3.125°C/W allows efficient heat transfer to external heatsink, critical for sustained 40 W operation.
Pb-free & RoHS	G-suffix confirms lead-free termination and full compliance with EU RoHS Directive 2011/65/EU.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD127G	Lower V_CEO (60 V), same TO-220 package, h_FE ≥25 at I_C = 3 A; lower f_T (3 MHz).	Suitable for ≤48 V systems only; not recommended for 60 V bus applications where 2N6107G's 70 V rating provides margin.	Select MJD127G only if system max V_CE stays below 55 V and thermal budget permits higher V_CE(sat).
BD249C	Higher V_CEO (80 V), TO-126 package (smaller footprint, higher R_JC = 5°C/W), h_FE ≥40 at I_C = 2 A.	Requires PCB redesign due to different package; limited to ≤25 W continuous dissipation without forced cooling.	Choose BD249C only when board space is constrained and voltage margin >80 V is needed-verify thermal interface for R_JC increase.

Compared with MJD127G and BD249C, the 2N6107G uniquely balances 70 V_CEO, 7 A current, TO-220 thermal performance (R_JC = 3.125°C/W), and Pb-free compliance-making it optimal for industrial 48–60 V switching and linear applications requiring proven reliability and heatsink compatibility.

FAQ

What is the maximum collector-emitter voltage rating for the 2N6107G?

The 2N6107G has a maximum collector-emitter sustaining voltage (V_CEO(sus)) of 70 Vdc at I_C = 100 mAdc and I_B = 0. This rating is confirmed in the "OFF CHARACTERISTICS" table on page 2 of the official onsemi datasheet (Rev. 12, June 2024). Exceeding this voltage risks avalanche breakdown and permanent device damage.

Is the 2N6107G pin-compatible with other transistors in the 2N61xx series?

Yes-the 2N6107G shares identical TO-220 pinout (B-E-C) and terminal assignments with 2N6109G and 2N6111G per the "ORDERING INFORMATION" and marking diagram on page 4 of the onsemi datasheet. However, V_CEO, V_CB, and h_FE differ across variants, so electrical substitution requires validation against circuit voltage and gain requirements.

Does the 2N6107G require a heatsink in normal operation?

Yes-the 2N6107G dissipates up to 40 W at T_C = 25°C, and its R_JC = 3.125°C/W necessitates a heatsink for any sustained power >5 W. Without thermal management, junction temperature will exceed 150°C even at modest loads; the metal tab must be electrically isolated and thermally coupled to a heatsink using appropriate mounting hardware.

What is the typical DC current gain (h_FE) of the 2N6107G at full load?

The 2N6107G guarantees h_FE ≥30 at I_C = 7.0 Adc and V_CE = 4.0 Vdc per the "ON CHARACTERISTICS" table on page 2 of the datasheet. This value is measured under pulsed conditions (duty cycle ≤2.0%) and defines the minimum base current (≥233 mA) required to saturate the 2N6107G at full 7 A collector current.

Is the 2N6107G suitable for switching applications above 100 kHz?

No-the 2N6107G is not optimized for high-frequency switching. Its f_T = 10 MHz and relatively high C_ob = 250 pF limit practical switching speeds to ≤50 kHz in hard-switched topologies. For >100 kHz operation, MOSFETs or RF-optimized BJTs with faster t_r/t_f and lower capacitance should be selected instead of the 2N6107G.
