Product details
Overview
MPS8098G from onsemi is an NPN general-purpose amplifier transistor in TO-92 package, rated for 60 VCEO, 500 mA continuous collector current, and 625 mW power dissipation at TA = 25°C. It delivers hFE ≥ 100 at IC = 1.0 mA and VCE = 5 V, with fT = 150 MHz, supporting low-noise amplification and switching in consumer and industrial signal conditioning circuits.
For engineers reviewing the MPS8098G datasheet, pinout, applications, or equivalent options, key selection criteria include its 60 V breakdown rating, TO-92 leaded package compatibility, DC current gain stability across temperature, saturation voltage under 0.4 V at 100 mA/5 mA drive, and Pb-free compliance per J-STD-609.
Technical Context
The MPS8098G operates as a silicon planar epitaxial NPN bipolar junction transistor optimized for linear amplification and medium-speed switching. Its design supports stable hFE across −55°C to +150°C junction temperature range and exhibits low output capacitance (Cobo = 6.0 pF) and input capacitance (Cibo = 25 pF) at 1 MHz, enabling wideband small-signal performance.
Thermal resistance values are RJA = 200°C/W (PCB-mounted) and RJC = 83.3°C/W, confirming suitability for through-hole applications with moderate power density. Safe operating area (SOA) curves validate operation up to 60 V and 500 mA under DC or pulsed conditions with ≤10% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum collector-emitter voltage before breakdown; defines upper rail limit in amplifier or switch stages. |
| IC (continuous) | 500 mA - Sustained collector current capability; supports medium-power driver and preamp stages. |
| PD @ TA = 25°C | 625 mW - Power dissipation limit on standard PCB; requires thermal derating above 25°C (5.0 mW/°C). |
| hFE | 100–300 - DC current gain range at IC = 1–100 mA; ensures predictable biasing in Class-A amplifiers. |
| fT | 150 MHz - Unity-gain bandwidth; enables RF amplification up to ~50 MHz with adequate gain margin. |
| VCE(sat) | ≤ 0.4 V @ IC = 100 mA, IB = 5 mA - Low saturation voltage reduces conduction loss in switching applications. |
| Cobo | 6.0 pF - Collector-base output capacitance; limits high-frequency roll-off and affects stability in tuned circuits. |
Pinout & Package
Package: TO-92 (Case 29-11), molded plastic, axial-leaded, Pb-free compliant (per J-STD-609). Standard through-hole mounting with 2.54 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current exit path for majority carriers | Connected to ground or low-impedance return; sets reference for bias network and emitter degeneration. |
| 2 (Base) | Control terminal for minority carrier injection | Receives bias current to modulate collector current; requires current-limiting resistor in most configurations. |
| 3 (Collector) | Current entry path for majority carriers | Connected to supply rail or load; carries amplified output current and dissipates most device power. |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE ≥ 100 at IC = 1 mA - Enables low-base-drive amplifier designs with minimal quiescent current. |
| Low saturation voltage | VCE(sat) ≤ 0.4 V - Reduces power loss and self-heating during switching, improving efficiency in digital interface drivers. |
| Wide bandwidth | fT = 150 MHz - Supports audio and low-MHz RF amplification without external compensation in common-emitter stages. |
| Robust thermal performance | RJC = 83.3°C/W - Allows direct heat transfer to PCB copper pour or heatsink tab when mounted with short leads. |
| Pb-free TO-92 package | RoHS-compliant construction - Meets global environmental regulations without compromising mechanical reliability or solderability. |

IC Role / Device Role / Timing Role: Low-noise, low-drift NPN transistor in discrete instrumentation amplifier front-end. Use Value: Cobo = 6.0 pF and Cibo = 25 pF reduce capacitive coupling noise; 625 mW PD allows conservative derating for long-term reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC547C | Lower VCEO (45 V), lower fT (300 MHz typ but not guaranteed min), hFE binning tighter (420–800) | Preferred where higher gain consistency is needed but voltage headroom is limited to ≤45 V | Select BC547C only if system rail is ≤45 V and tighter hFE spread is required; verify SOA at target IC/VCE. |
| MPSA18 | Higher VCEO (50 V), same TO-92 package, fT = 100 MHz (min), hFE ≥ 100 @ IC = 10 mA | Suitable for higher-voltage analog stages up to 50 V, with slightly reduced bandwidth | Choose MPSA18 when operating near 50 V rails and 100 MHz bandwidth suffices; confirm thermal margin given lower PD (625 mW same but RJA higher). |
Compared with BC547C and MPSA18, the MPS8098G offers superior voltage margin (60 V), guaranteed minimum fT (150 MHz), and documented thermal resistance (RJC = 83.3°C/W), making it preferable for industrial-grade amplifiers requiring robustness across temperature and supply variations.

FAQ
What is the maximum collector-emitter voltage rating for the MPS8098G?
The MPS8098G has a maximum collector-emitter voltage (VCEO) rating of 60 Vdc, verified per the onsemi datasheet (MPS8098/D, Rev. 5). This rating applies under specified test conditions (IC = 10 mA, IB = 0) and defines the absolute maximum voltage the device can withstand in open-base configuration without breakdown. Exceeding this value risks permanent damage to the MPS8098G.
Is the MPS8098G RoHS-compliant and Pb-free?
Yes, the MPS8098G is explicitly marked as Pb-free in the onsemi datasheet ordering table and complies with RoHS Directive 2011/65/EU. The "G" suffix denotes Pb-free packaging (TO-92), confirmed by the manufacturer's J-STD-609 classification. The MPS8098G uses matte tin lead finish and meets JEDEC moisture sensitivity level (MSL) requirements for standard reflow profiles.
What is the DC current gain (hFE) range of the MPS8098G at typical operating conditions?
The MPS8098G exhibits hFE ≥ 100 at IC = 1.0 mA and VCE = 5.0 V, with a maximum of 300 under the same conditions. At IC = 100 mA, hFE drops to ≥75. These values are measured at TA = 25°C and are guaranteed minimums per the electrical characteristics table in the official MPS8098/D datasheet. Designers should apply appropriate derating for temperature and current extremes when using the MPS8098G.
Can the MPS8098G be used in switching applications, and what is its typical saturation voltage?
Yes, the MPS8098G is suitable for medium-speed switching applications. Its typical collector-emitter saturation voltage (VCE(sat)) is ≤0.4 V at IC = 100 mA and IB = 5.0 mA, and ≤0.3 V at IC = 100 mA and IB = 10 mA. These low saturation values minimize conduction losses, making the MPS8098G effective in digital interface drivers and relay/motor control stages where efficient power transfer is critical.
What is the thermal resistance junction-to-ambient (RJA) for the MPS8098G in standard PCB mounting?
The thermal resistance junction-to-ambient (RJA) for the MPS8098G is 200°C/W when soldered onto a typical printed circuit board, as specified in the Thermal Characteristics section of the onsemi MPS8098/D datasheet. This value assumes standard FR-4 board layout with 1 in² copper pour; actual RJA may improve with enhanced copper area or thermal vias. For thermal design, the MPS8098G must be derated by 5.0 mW/°C above 25°C ambient.
