Product details
Overview
MPS8098RLRA 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 audio preamplifier, signal switching, and low-power linear amplification stages.
For engineers reviewing the MPS8098RLRA datasheet, pinout, applications, or equivalent options, key selection criteria include its 60 V breakdown rating, TO-92 leaded package compatibility with through-hole prototyping and legacy industrial controls, verified DC gain stability across −55°C to +150°C junction temperature, and Pb-free tape-and-reel packaging for automated SMT assembly.
Technical Context
The MPS8098RLRA operates as a silicon NPN bipolar junction transistor optimized for medium-speed amplification and switching. Its 150 MHz fT supports RF front-end buffering up to VHF band, while VCE(sat) ≤ 0.4 V at IC = 100 mA / IB = 5 mA enables efficient low-voltage saturation in driver circuits.
Thermal design is enabled by RJA = 200°C/W (PCB-mounted) and RJC = 83.3°C/W, allowing operation up to +150°C junction temperature. The device uses standard TO-92 pinout (Emitter–Base–Collector, pins 1–2–3), with VEBO = 4.0 V and Cobo = 6.0 pF at VCB = 5 V, confirming suitability for low-noise analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum safe collector-emitter voltage before avalanche breakdown; defines upper rail limit in 48 V industrial control interfaces. |
| IC (continuous) | 500 mA - Continuous collector current handling; supports relay drivers and LED array switches without forced cooling. |
| PD @ TA = 25°C | 625 mW - Power dissipation limit at ambient; requires ≥ 200°C/W thermal resistance for safe operation at full current. |
| hFE | 100–300 - DC current gain range at IC = 1–100 mA; ensures stable biasing in Class-A audio preamps and sensor interface amplifiers. |
| fT | 150 MHz - Unity-gain bandwidth; enables small-signal amplification up to ~50 MHz with usable gain margin. |
| VCE(sat) | ≤ 0.4 V @ IC/IB = 20 - Low saturation voltage reduces conduction loss in digital logic level translators and PWM output stages. |
| Cobo | 6.0 pF @ VCB = 5 V - Output capacitance limits high-frequency gain roll-off; critical for RF matching network design. |
Pinout & Package
Package: TO-92 (Case 29-11, Style 1), epoxy-molded through-hole package with 2.54 mm lead pitch, JEDEC-standard footprint, and Pb-free termination (per ordering suffix 'G' variant). Compatible with wave soldering and manual prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Reference node for bias networks; connects to ground or negative rail in common-emitter configurations. |
| 2 (Base) | Control input | Receives base drive current to modulate collector current; requires series resistor to limit IB per hFE and load requirements. |
| 3 (Collector) | Current source terminal | Delivers amplified output current to load; connects to positive supply via collector resistor or direct drive. |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE ≥ 100 at IC = 1 mA ensures reliable turn-on with minimal base drive in microcontroller GPIO-driven circuits. |
| 150 MHz transition frequency | Supports broadband signal amplification up to VHF, enabling use in IF amplifiers and low-cost RF detector stages. |
| Low VCE(sat) | ≤ 0.4 V at IC = 100 mA minimizes power loss in saturated-switch applications such as lamp dimmers and solenoid drivers. |
| Wide operating temperature | −55°C to +150°C junction range allows deployment in automotive engine compartments and industrial motor control enclosures. |
| Pb-free tape-and-reel packaging | 2,000-unit reel (suffix 'RLRA') enables direct integration into pick-and-place SMT lines without lead-forming or manual insertion. |

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 |
|---|---|---|---|
| BC547B | VCEO = 45 V, hFE = 200–450, fT = 300 MHz, same TO-92 package | Lower voltage rating limits use in 48 V systems; higher fT suits faster switching but increases noise sensitivity | Select when higher speed and tighter hFE tolerance are prioritized over voltage headroom. |
| MPSA18 | VCEO = 45 V, hFE = 100–300, fT = 120 MHz, TO-92 package | Reduced fT and identical gain range; lower Cobo = 4.5 pF improves HF stability in tuned circuits | Prefer for low-noise RF amplifier stages where 120 MHz bandwidth suffices and capacitance minimization is critical. |
Compared with BC547B and MPSA18, the MPS8098RLRA provides superior 60 V breakdown margin for industrial 48 V rails, maintains competitive 150 MHz fT with proven thermal robustness to +150°C, and offers Pb-free tape-and-reel logistics aligned with modern SMT production flows.

FAQ
What is the maximum collector-emitter voltage rating for the MPS8098RLRA?
The MPS8098RLRA has a guaranteed minimum VCEO rating of 60 Vdc under test conditions of IC = 10 mA and IB = 0. This rating defines the absolute maximum voltage that can be applied between collector and emitter while keeping the device in cutoff, and must not be exceeded in circuit design to prevent avalanche breakdown or permanent damage. The MPS8098RLRA is therefore suitable for 48 V nominal systems with safety margin.
Is the MPS8098RLRA compatible with Pb-free reflow soldering processes?
Yes, the MPS8098RLRA is manufactured with Pb-free terminations and qualified for standard SnAgCu (SAC305) reflow profiles. Its TO-92 package meets J-STD-020 moisture sensitivity level (MSL) 1, permitting unlimited floor life and compatibility with peak reflow temperatures up to 260°C. The 'RLRA' suffix explicitly denotes tape-and-reel packaging with Pb-free finish, verified per onsemi's Pb-Free Packaging Specification.
What is the typical DC current gain (hFE) of the MPS8098RLRA at 10 mA collector current?
The MPS8098RLRA exhibits hFE ≥ 100 at IC = 10 mA and VCE = 5 V, with a typical value of 200 and maximum of 300 under those conditions. This gain range ensures predictable bias point stability in common-emitter amplifier designs and sufficient drive capability for low-power switching loads without requiring excessive base current from microcontrollers or logic gates.
Does the MPS8098RLRA have documented thermal resistance values for PCB-mounted operation?
Yes, the MPS8098RLRA specifies RJA = 200°C/W when soldered to a standard FR-4 PCB per JEDEC 51-7 guidelines, and RJC = 83.3°C/W for junction-to-case conduction. These values enable accurate junction temperature estimation using TJ = TA + PD × RJA, confirming safe operation up to +150°C junction temperature at 625 mW dissipation only if ambient remains ≤ +25°C.
How does the MPS8098RLRA differ from the MPS8099RLRA variant?
The MPS8098RLRA and MPS8099RLRA share identical TO-92 packaging and pinout but differ in maximum voltage ratings: the MPS8098RLRA is rated for VCEO = 60 V and VCBO = 60 V, whereas the MPS8099RLRA is rated for 80 V in both parameters. All other specifications-including hFE, fT, IC, PD, and thermal characteristics-are identical. Designers select MPS8098RLRA for cost-optimized 48 V systems and MPS8099RLRA for higher-voltage 72 V or transient-tolerant applications.
