Product details
Overview
2N5087RLRAG from onsemi is a PNP silicon small-signal amplifier transistor in TO-92 package, rated for VCEO = 50 V, IC = 50 mA, and hFE = 250–800 (at IC = 1.0–10 mA), optimized for low-noise audio preamplification and precision current mirror applications.
For engineers reviewing the 2N5087RLRAG datasheet, pinout, applications, or equivalent options, this device is selected for high-current-gain stability across temperature, low VCE(sat) ≤ 0.3 V at IC/IB = 10, and fT = 40 MHz - critical for analog front-end gain stages and bias control circuits.
Technical Context
The 2N5087RLRAG operates as a linear PNP bipolar junction transistor with fixed-emitter configuration, supporting DC-coupled amplification and active load switching. Its hFE variation is bounded between −55°C and +125°C, and its noise figure remains ≤2.0 dB at 1 kHz with RS = 3.0 kΩ.
Thermal design is enabled by RJA = 200°C/W (ambient) and RJC = 83.3°C/W (case), with safe operating area validated up to 100 mA at VCE = 10 V under 1 ms pulses. The device exhibits Ccb = 4.0 pF at VCB = 5 V, supporting stable high-frequency bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 Vdc - Maximum collector-emitter voltage before breakdown; enables use in ±24 V rail systems with margin. |
| IC (continuous) | 50 mAdc - Continuous collector current rating; supports medium-gain active loads without derating at 25°C. |
| hFE | 250–800 - DC current gain range at IC = 1.0–10 mA; ensures predictable bias point stability in emitter-follower configurations. |
| fT | 40 MHz - Current-gain bandwidth product at IC = 500 µA; sufficient for audio band amplification and low-speed signal conditioning. |
| VCE(sat) | ≤0.3 Vdc at IC = 10 mAdc, IB = 1.0 mAdc - Low saturation voltage reduces power loss in switch-mode bias networks. |
| NF | ≤2.0 dB at 1 kHz, RS = 3.0 kΩ - Confirmed low-noise performance for microphone preamp and sensor interface stages. |
| RJA | 200°C/W - Junction-to-ambient thermal resistance; defines maximum power dissipation (625 mW) in still-air PCB mounting. |
Pinout & Package
2N5087RLRAG uses the standard TO-92 (Case 29-11) through-hole package with bent leads, Pb-free finish, and marking "2N5087" followed by date code. Pin 1 is Emitter, Pin 2 is Base, Pin 3 is Collector - verified per onsemi's official marking diagram and package outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal for PNP operation | Connected to higher potential rail; sets reference for base-emitter forward bias and current sourcing capability. |
| 2 (Base) | Control input for minority-carrier injection | Receives base drive current to modulate collector current; requires external bias network for stable Q-point. |
| 3 (Collector) | Output current sink terminal | Delivers amplified current to load; polarity inverted relative to base drive - essential for common-emitter gain stages. |
Key Features
| Feature | Design Value |
|---|---|
| High hFE consistency | Min 250 at IC = 1.0 mAdc ensures reliable current mirroring with <±5% unit-to-unit spread in matched pairs. |
| Low noise figure | ≤2.0 dB at 1 kHz enables use in electret microphone preamps where SNR > 60 dB is required. |
| Pb-free TO-92 packaging | RoHS-compliant construction with tape-and-reel delivery (2000 units/reel); compatible with standard wave soldering profiles. |
| Wide TJ range | −55°C to +150°C operation supports industrial temperature-grade designs without derating below −40°C ambient. |
| Controlled Ccb | 4.0 pF max at VCB = 5 V limits Miller effect in high-gain CE stages, preserving phase margin up to 10 MHz. |
Applications
| Audio Preamp Stage | Current Mirror Reference |
|---|---|
|

| Active Load Switch | Low-Voltage Level Shifter |
|
Use Scenario: High-side current-controlled load switching in 3.3 V logic-controlled analog subsystems. IC Role / Device Role / Timing Role: Saturated PNP switch driving resistive loads up to 40 mA. Use Value: VCE(sat) ≤0.3 V at IC/IB = 10 minimizes dropout and self-heating during continuous conduction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP small-signal amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC557B | hFE = 200–450 (lower max gain), VCEO = 45 V, TO-92 but non-Pb-free option available | Marginally lower voltage headroom and gain; suitable only where 45 V rating suffices and RoHS not mandated | Select when cost sensitivity outweighs need for 50 V rating and extended hFE range. |
| MPSA92 | VCEO = 300 V, IC = 500 mA, fT = 50 MHz, TO-92 but higher power dissipation (625 mW same, but RJA = 200°C/W unchanged) | Over-specified for low-voltage audio; excessive VCEO increases capacitance and reduces fT efficiency at low bias | Choose only if system requires >100 V isolation or high-voltage active load switching beyond 50 V. |
Compared with BC557B and MPSA92, the 2N5087RLRAG delivers optimal balance of 50 V rating, 250–800 hFE, and 2.0 dB noise - making it the preferred choice for precision low-noise, medium-voltage analog gain blocks where both performance and RoHS compliance are mandatory.

FAQ
What is the maximum collector-emitter voltage rating for the 2N5087RLRAG?
The 2N5087RLRAG has a guaranteed minimum VCEO rating of 50 Vdc, verified per onsemi's datasheet under IC = 1.0 mAdc and IB = 0 conditions. This allows safe operation in circuits with up to ±24 V rails while maintaining 2 V margin against breakdown. Exceeding this voltage risks irreversible junction failure.
Does the 2N5087RLRAG support low-noise audio applications?
Yes - the 2N5087RLRAG is characterized for noise figure ≤2.0 dB at 1 kHz with RS = 3.0 kΩ, and its typical noise voltage is below 5 nV/√Hz at 1 kHz. These values are confirmed in Figures 3–5 of the official datasheet, making it suitable for electret microphone preamplifiers and sensor signal conditioning where SNR > 60 dB is required.
What is the DC current gain range of the 2N5087RLRAG at different collector currents?
The 2N5087RLRAG provides hFE = 250 (min) at IC = 1.0 mAdc, hFE = 250 (min) at IC = 10 mAdc, and hFE = 250 (min) at IC = 100 µAdc - all tested at VCE = 5.0 Vdc and TA = 25°C. The maximum hFE reaches 800 at IC = 1.0 mAdc, enabling precise bias design across multiple operating points.
Is the 2N5087RLRAG RoHS compliant and what packaging format does it use?
Yes - the 2N5087RLRAG is explicitly marked "Pb-Free" in onsemi's ordering information and shipped in tape-and-reel format (2000 units per reel). Its TO-92 package (Case 29-11) meets RoHS Directive 2011/65/EU requirements, with lead finish qualified for standard reflow and wave soldering processes.
How does thermal resistance affect power handling for the 2N5087RLRAG in PCB designs?
The 2N5087RLRAG has RJA = 200°C/W (junction-to-ambient) and RJC = 83.3°C/W (junction-to-case). At 25°C ambient, its 625 mW maximum dissipation drops to ~375 mW at 70°C ambient - calculated via linear derating (5.0 mW/°C above 25°C). Proper copper pour and airflow are essential to maintain TJ ≤150°C in continuous operation.
