Product details

Overview

MPS6717G from onsemi is an NPN silicon general-purpose amplifier transistor in TO-92 package, rated for 1.0 W total device dissipation at T_A = 25°C, V_CEO = 80 V, I_C = 500 mA, and h_FE = 80–250 (at I_C = 50–250 mA). It serves as a medium-power linear or switching gain stage in low-frequency analog and power control circuits.

For engineers reviewing the MPS6717G datasheet, pinout, applications, or equivalent options, key selection considerations include its 80 V V_CEO, 1.0 W ambient-rated power handling, TO-92 thermal resistance (R_JA = 125°C/W), and verified DC current gain across temperature (−55°C to +150°C).

Technical Context

This NPN bipolar junction transistor operates in active, saturation, and cutoff regions with defined safe operating area (SOA) limits up to 500 mA and 80 V. Its h_fe bandwidth product reaches 30 MHz at I_C = 200 mA and V_CE = 5 V, supporting audio and low-speed switching applications.

Thermal design relies on R_JC = 50°C/W and R_JA = 125°C/W, requiring heatsinking or PCB copper area when dissipating >0.5 W continuously. V_BE(on) ≤ 1.2 V and V_CE(sat) ≤ 0.5 V at I_C/I_B = 25 ensure efficient drive in saturated-switching configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum collector-emitter voltage before breakdown; defines safe operating voltage headroom in amplifier or switch designs.
I_C (max)	500 mA - Continuous collector current limit; sets maximum load drive capability without thermal runaway.
P_D @ T_A = 25°C	1.0 W - Ambient-rated power dissipation; determines usable output power in non-heatsinked TO-92 layouts.
h_FE	80–250 - DC current gain range at I_C = 50–250 mA; enables predictable base drive sizing for linear or saturated operation.
R_JA	125°C/W - Junction-to-ambient thermal resistance; informs minimum PCB copper area or airflow needed for thermal stability.
V_CE(sat)	≤ 0.5 V - Collector-emitter saturation voltage at I_C = 250 mA, I_B = 10 mA; minimizes conduction loss in switching applications.

Pinout & Package

Package: TO-92 (Case 29-10, Style 1), Pb-free, through-hole mounting. Dimensions conform to ON Semiconductor mechanical outline 98AON52857E.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current sink terminal; connects to ground or low-side reference; polarity defines NPN operation.
2	Base	Control input; requires current-limited drive (typically 1–10 mA) to bias transistor into active/saturation region.
3	Collector	Current source terminal; connects to load and supply rail; handles full output current and voltage stress.

Key Features

Feature	Design Value
1.0 W ambient power rating	Enables medium-power amplification or switching without external heatsink in compact TO-92 footprint.
80 V V_CEO breakdown	Supports operation in 24 V, 48 V, and 60 V industrial control rails with margin against transients.
h_FE = 80–250 range	Allows robust base drive design across production lots and temperature extremes (−55°C to +150°C).
V_CE(sat) ≤ 0.5 V	Reduces power loss and self-heating during high-current switching, improving efficiency and reliability.
Pb-free TO-92 packaging	Meets RoHS compliance requirements without derating; compatible with standard SnPb and lead-free solder processes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC337-40	V_CEO = 45 V, P_D = 625 mW, h_FE = 250–630 - lower voltage/power rating, higher gain spread.	Suitable only for ≤30 V, ≤400 mA loads; not recommended for 48 V rail or 1 W dissipation.	Select BC337-40 only when lower cost and tighter gain tolerance are prioritized over voltage/power headroom.
2N2222A	V_CEO = 40 V, P_D = 500 mW, h_FE = 100–300 - reduced voltage and power capability vs. MPS6717G.	Limited to low-voltage logic-level switching and signal amplification; unsuitable for industrial 24/48 V systems.	Choose 2N2222A for legacy designs or where established qualification data outweighs performance trade-offs.

Compared with BC337-40 and 2N2222A, the MPS6717G provides 80 V breakdown and 1.0 W dissipation - critical for reliable operation in 48 V industrial controls and higher-power analog stages where alternatives require derating or supplemental heatsinking.

FAQ

What is the maximum continuous collector current for the MPS6717G?

The MPS6717G supports a maximum continuous collector current (I_C) of 500 mA at T_A = 25°C. This rating assumes adequate PCB copper area or ambient airflow to maintain junction temperature within −55°C to +150°C. At elevated ambient temperatures, derating applies per the 8.0 mW/°C specification above 25°C.

Does the MPS6717G have Pb-free packaging?

Yes, the MPS6717G is explicitly designated as a Pb-free device in the ordering information and marking diagram. The "G" suffix indicates RoHS-compliant packaging, and the device meets JEDEC J-STD-609 Category 1a requirements for lead-free soldering compatibility.

What is the typical DC current gain (h_FE) of the MPS6717G at 250 mA collector current?

At I_C = 250 mA and V_CE = 1.0 V, the MPS6717G exhibits a minimum h_FE of 50 and a typical value near 120–180, as confirmed by Figure 1 in the datasheet. This gain remains stable across −55°C to +125°C, supporting robust base drive design in wide-temperature environments.

Can the MPS6717G be used in switching applications?

Yes, the MPS6717G is suitable for switching applications, with V_CE(sat) ≤ 0.5 V at I_C = 250 mA and I_B = 10 mA. Its SOA curve (Figure 7) confirms safe operation up to 500 mA and 80 V in pulsed or DC switching modes, provided thermal limits are observed.

What is the thermal resistance from junction to case (R_JC) for the MPS6717G?

The MPS6717G has a specified thermal resistance of R_JC = 50°C/W. This value enables effective heatsinking when the collector tab is soldered to a large copper pour or attached to an external heatsink, allowing sustained operation near its 2.5 W case-rated dissipation limit.
