Product details
Overview
2SA1586-GR,LF from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor designed for low-frequency and audio-frequency amplifier stages. It delivers VCEO = −50 V, IC(max) = −150 mA, hFE = 200–400 (GR grade), NF = 1 dB (typ.), and operates in the USM surface-mount package with verified pinout Base–Emitter–Collector (1–2–3).
For engineers reviewing the 2SA1586-GR,LF datasheet, 2SA1586-GR,LF pinout, 2SA1586-GR,LF application, or 2SA1586-GR,LF equivalent, key selection considerations include AEC-Q101 qualification for automotive use, hFE linearity (0.95 typ.), low-noise performance at 1 kHz, and complementary pairing with 2SC4116 in push-pull audio output stages.
Technical Context
This PNP transistor employs epitaxial base construction to achieve high voltage blocking and stable DC current gain across its specified collector current range. Its hFE classification GR (200–400) ensures consistent amplification linearity-confirmed by hFE(IC = −0.1 mA)/hFE(IC = −2 mA) = 0.95 (typ.)-and supports low-distortion signal handling in linear amplifier topologies.
The device is characterized for operation up to Tj = 125 °C with PC = 200 mW (on FR4 board), and exhibits Cob = 7 pF (typ.) at VCB = −10 V, supporting stable frequency response below 10 MHz. Its fT = 80 MHz (min) enables reliable performance in audio and sub-RF switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Package | USM (SOT-323): 2.1 × 1.25 × 0.9 mm footprint enables dense placement in portable audio PCBs. |
Pinout & Package
2SA1586-GR,LF is housed in the USM (Ultra Small Mold) package-a JEDEC-standard SOT-323 variant measuring 2.1 × 1.25 × 0.9 mm with 3 terminals and 6.0 mg typical weight. The package supports reflow soldering and meets RoHS requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to enable conduction. |
| 2 | Emitter | Current source terminal; connected to higher potential (e.g., VCC) in common-emitter amplifier configurations. |
| 3 | Collector | Output terminal; sinks current to load or next stage; reverse-biased relative to emitter during active operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability per stress test requirements (HTOL, TC, HAST, etc.), enabling use in infotainment power stages. |
| hFE linearity ratio | 0.95 (typ.): Minimizes harmonic distortion in Class-A amplifier biasing where gain constancy across operating current is critical. |
| Complementary pair | Matched to 2SC4116 (NPN): Enables symmetrical push-pull output stages with balanced thermal and gain characteristics. |
| Low noise figure | 1 dB (typ.) at 1 kHz: Reduces audible hiss in battery-powered audio recorders and portable mixers. |
Applications
| Audio Preamp Stage | Automotive Infotainment Output |
|---|---|
Use Scenario: Low-noise voltage amplification of microphone or line-level signals before ADC conversion.

NF and hFE linearity preserve signal integrity in battery-powered recording devices. | Use Scenario: Driver stage in OEM car radio speaker output modules operating from 12 V battery rails. IC Role / Device Role / Timing Role: Complementary PNP switch in Class-AB output pair with 2SC4116. Use Value: AEC-Q101 qualification and −50 V VCEO ensure robustness against load-dump transients. |
| Portable Audio Amplifier | Industrial Sensor Signal Conditioning |
Use Scenario: Final gain stage in compact headphone amplifiers requiring low quiescent current and THD < 0.5%. IC Role / Device Role / Timing Role: Linear PNP emitter-follower buffer delivering low-impedance drive to 32 Ω loads. Use Value: −150 mA IC capability and 200–400 hFE support stable bias under varying headphone impedance. | Use Scenario: Amplification of millivolt-level thermocouple or strain gauge outputs in factory-floor instrumentation. IC Role / Device Role / Timing Role: DC-coupled PNP amplifier configured for precision gain and offset control. Use Value: Tight hFE spread (GR grade) and low ICBO (−0.1 µA max) reduce calibration drift over temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP bipolar transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SA1037AK-RL | hFE = 120–270 (K grade); VCEO = −50 V; same USM package; fT = 100 MHz (min) | Higher fT but narrower hFE range; not AEC-Q101 qualified | Preferred for non-automotive RF-adjacent audio filters where speed outweighs linearity. |
| MMBT4403-7-F | hFE = 100–300; VCEO = −40 V; SOT-23 package; NF = 10 dB (max) | Lower voltage rating and higher noise floor; automotive-qualified per AEC-Q101 | Used where board space permits larger SOT-23 and −40 V rating suffices for 5–9 V systems. |
Compared with 2SA1586-GR,LF, the 2SA1037AK-RL offers higher bandwidth but reduced hFE linearity, while MMBT4403-7-F trades voltage headroom and noise performance for broader automotive qualification coverage and legacy footprint compatibility.

FAQ
What is the hFE classification for 2SA1586-GR,LF?
The "GR" suffix in 2SA1586-GR,LF denotes the hFE bin: 200 to 400 at VCE = −6 V and IC = −2 mA. This high-gain, tightly binned classification ensures predictable DC biasing and gain stability across production units, making 2SA1586-GR,LF especially suitable for precision audio amplifier designs where gain matching matters.
Is 2SA1586-GR,LF qualified for automotive applications?
Yes, 2SA1586-GR,LF is explicitly AEC-Q101 qualified per Toshiba's orderable part number documentation. This qualification covers temperature cycling, highly accelerated life testing, and humidity testing-validating its suitability for under-hood and infotainment applications where reliability under thermal and electrical stress is mandatory.
What package type does 2SA1586-GR,LF use, and what are its dimensions?
2SA1586-GR,LF uses the USM (Ultra Small Mold) package-identical to JEDEC SOT-323-with dimensions of 2.1 mm × 1.25 mm × 0.9 mm and a typical weight of 6.0 mg. Its pinout is standardized: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector, enabling direct integration into high-density PCB layouts.
How does the noise figure of 2SA1586-GR,LF compare to similar PNP transistors?
2SA1586-GR,LF achieves a typical noise figure of 1 dB at 1 kHz (RG = 10 kΩ), significantly lower than standard PNP transistors like MMBT4403-7-F (10 dB max). This low-noise performance stems from optimized epitaxial base design and tight process control, making 2SA1586-GR,LF ideal for microphone preamps and other sensitive analog front-ends.
What is the complementary NPN transistor for 2SA1586-GR,LF?
The official complementary NPN transistor for 2SA1586-GR,LF is the 2SC4116, as stated in Toshiba's datasheet Feature #7. Both share matched VCEO (−50 V), IC(max) (−150 mA), and hFE grading structure, enabling symmetrical push-pull amplifier designs with balanced thermal behavior and gain tracking across temperature.
