Product details
Overview
MPS8099RLRAG from onsemi is an NPN general-purpose amplifier transistor in TO-92 package, rated for 80 VCEO, 500 mA continuous collector current, and 625 mW power dissipation at 25°C ambient. It delivers hFE = 100–300 at IC = 1.0 mA, VCE = 5 V, and fT = 150 MHz, supporting linear amplification and switching in low-voltage analog signal paths and discrete logic interfaces.
For engineers reviewing the MPS8099RLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include its VCEO/IC rating margin, DC current gain consistency across bias points, saturation voltage under defined drive conditions, thermal resistance (RJA = 200°C/W), and Pb-free tape-and-reel packaging compliance.
Technical Context
This NPN bipolar junction transistor operates in active, saturation, and cutoff regions with verified breakdown voltages: V(BR)CEO = 80 V (IC = 10 mA), V(BR)CBO = 80 V (IC = 100 μA), and V(BR)EBO = 5.0 V (IE = 10 μA). Its small-signal performance includes fT = 150 MHz at IC = 10 mA, VCE = 5 V, and input/output capacitances Cibo = 30 pF and Cobo = 8.0 pF at specified bias conditions.
Thermal design is constrained by RJA = 200°C/W (PCB-mounted) and RJC = 83.3°C/W, with safe operating area (SOA) validated up to 400 mA and 80 V in continuous DC operation. Derating is required above 25°C ambient at 5.0 mW/°C for ambient-limited dissipation and 12 mW/°C for case-limited operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines upper rail limit in amplifier or switch designs. |
| IC (continuous) | 500 mA - Sustained collector current capability; supports medium-power driver stages without forced cooling. |
| hFE (min–max) | 100–300 - DC current gain range at IC = 1.0 mA, VCE = 5 V; enables predictable base drive sizing in linear and saturated operation. |
| fT | 150 MHz - Unity-gain frequency; confirms suitability for RF preamp, oscillator, and broadband audio applications up to ~30 MHz. |
| VCE(sat) | 0.3–0.4 V - Collector-emitter saturation voltage at IC = 100 mA, IB = 5–10 mA; ensures low conduction loss in switching applications. |
| PD @ TA = 25°C | 625 mW - Total device dissipation limit with no heatsink; sets maximum power-handling envelope in ambient-cooled PCB layouts. |
| RJA | 200°C/W - Junction-to-ambient thermal resistance; determines temperature rise per watt in standard FR-4 mounting (per Note 1). |
Pinout & Package
Package: TO-92 (Case 29-11), straight-lead, Pb-free, tape-and-reel (2000 units/reel). Dimensions conform to ANSI Y14.5M and ASME Y14.5M standards, with body height 4.45–5.20 mm, lead pitch 2.54 mm, and seating plane defined per JEDEC TO-92 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Reference node for base-emitter junction; connects to ground or low-impedance return path in common-emitter configurations. |
| 2 (Base) | Control input | Receives forward-biased current to modulate collector current; requires series resistor to limit IB and ensure stable hFE-based operation. |
| 3 (Collector) | Current source terminal | Delivers amplified output current; connects to load and supply rail; must remain below VCEO during transients and switching. |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE ≥ 100 at IC = 1.0 mA ensures reliable low-current switching and stable biasing in high-input-impedance amplifier stages. |
| Low saturation voltage | VCE(sat) ≤ 0.4 V at IC = 100 mA minimizes power loss and self-heating in digital logic interface and relay driver circuits. |
| 150 MHz fT | Supports wideband amplification up to 30 MHz with minimal gain roll-off; suitable for IF amplifiers and clock buffer stages. |
| 80 V breakdown rating | Enables use in 24–48 V industrial control rails and automotive subsystems with transient margin against load-dump spikes. |
| Pb-free TO-92 packaging | Complies with RoHS Directive 2011/65/EU; compatible with lead-free reflow profiles and automated assembly processes. |

|---|---|
Use Scenario: Amplifying low-level microphone or piezoelectric sensor outputs in battery-powered portable audio recorders. IC Role / Device Role / Timing Role: NPN small-signal amplifier in common-emitter configuration with emitter degeneration for linearity and gain stability. Use Value: hFE = 100–300 and fT = 150 MHz enable >20 kHz bandwidth with <1% THD at 100 mVpp input, while VCE(sat) < 0.4 V reduces quiescent power in Class-A biasing. | Use Scenario: Converting 4–20 mA current-loop signals from pressure or temperature transmitters into 0–5 V analog outputs for PLC ADC inputs. IC Role / Device Role / Timing Role: Discrete NPN transistor used as a grounded-emitter current-to-voltage converter with precision shunt feedback. Use Value: Tight V(BR)CEO = 80 V and low Cobo = 8.0 pF ensure immunity to 36 V loop supply transients and minimal phase shift at 1 kHz signal frequencies. |
| Discrete Logic Level Shifter | LED Driver for Indicator Panels |
Use Scenario: Translating 3.3 V microcontroller GPIO outputs to drive 5–12 V logic inputs in mixed-voltage industrial HMIs. IC Role / Device Role / Timing Role: Saturated-switch NPN transistor acting as an open-collector inverter with pull-up to higher rail. Use Value: VCE(sat) ≤ 0.4 V at IC = 100 mA guarantees <0.5 V output low level across temperature, enabling clean TTL/CMOS compatibility. | Use Scenario: Driving 20 mA indicator LEDs in panel-mounted equipment with 5 V or 12 V supply rails and space-constrained PCBs. IC Role / Device Role / Timing Role: Constant-current switch with base resistor limiting IB to maintain IC ≈ 20 mA in saturation. Use Value: 500 mA IC rating and 625 mW PD allow parallel LED strings or short-duration pulse driving without thermal derating. |
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 | VCEO = 45 V, hFE = 420–800 (min 110), fT = 300 MHz, TO-92 package | Higher gain and fT, but lower voltage rating limits use in 48 V systems | Select BC547C when higher bandwidth and tighter hFE tolerance are prioritized over voltage headroom. |
| MPSA18 | VCEO = 45 V, hFE = 100–300, fT = 100 MHz, TO-92 package | Lower fT and same hFE range, but optimized for low-noise audio preamps | Choose MPSA18 where noise figure < 4 dB at 1 kHz is critical, accepting reduced RF capability. |
Compared with BC547C and MPSA18, MPS8099RLRAG provides superior voltage margin (80 V vs. 45 V) for industrial 24–48 V rails, retains competitive fT (150 MHz) and hFE consistency, and offers Pb-free tape-and-reel packaging aligned with modern SMT production requirements.

FAQ
What is the maximum collector-emitter voltage rating for MPS8099RLRAG?
The MPS8099RLRAG has a maximum collector-emitter voltage rating of 80 Vdc (V(BR)CEO), tested at IC = 10 mA with IB = 0. This rating defines the absolute upper limit for DC or peak repetitive voltage applied between collector and emitter in open-base configuration, and must be respected with appropriate safety margin in circuit design to prevent avalanche breakdown.
Does MPS8099RLRAG support high-frequency amplification?
Yes, the MPS8099RLRAG supports high-frequency amplification with a current-gain–bandwidth product (fT) of 150 MHz, measured at IC = 10 mA, VCE = 5 V, and f = 100 MHz. This enables stable small-signal gain up to approximately 30 MHz in common-emitter configurations, making it suitable for IF amplifiers, clock buffers, and broadband audio preamplifiers.
What is the DC current gain range of MPS8099RLRAG at typical operating conditions?
The DC current gain (hFE) of MPS8099RLRAG ranges from 100 to 300 at IC = 1.0 mA and VCE = 5.0 V, and remains ≥100 at IC = 10 mA and ≥75 at IC = 100 mA. This graded gain profile allows predictable base drive calculation across multiple bias points in both linear and switching applications.
How is thermal performance characterized for MPS8099RLRAG?
MPS8099RLRAG has a junction-to-ambient thermal resistance (RJA) of 200°C/W when soldered to a typical PCB, and junction-to-case resistance (RJC) of 83.3°C/W. Power dissipation must be derated by 5.0 mW/°C above 25°C ambient for PCB-limited operation, and its SOA curve validates safe DC operation up to 400 mA and 80 V without second breakdown.
Is MPS8099RLRAG supplied in Pb-free packaging?
Yes, MPS8099RLRAG is supplied in a Pb-free TO-92 package, as indicated by the "G" suffix in the part number and confirmed in the ordering information table. It complies with RoHS Directive 2011/65/EU and is qualified for lead-free reflow soldering per J-STD-020, with full traceability and material declarations available upon request.
