Product details
Overview
2SC2712-GR,LXHF from Toshiba Electronic Devices & Storage Corporation is a silicon NPN epitaxial bipolar transistor designed for low-frequency and audio-frequency amplifier stages, featuring VCEO = 50 V, IC(max) = 150 mA, hFE = 200–400 (GR grade), NF = 1 dB (typ.), and AEC-Q101 qualification for automotive use.
For engineers reviewing the 2SC2712-GR,LXHF datasheet, 2SC2712-GR,LXHF pinout, 2SC2712-GR,LXHF application, or 2SC2712-GR,LXHF equivalent, key selection criteria include hFE linearity (0.95 typ.), low-noise performance at 1 kHz, S-Mini package thermal limits, and automotive-grade reliability validation under AEC-Q101.
Technical Context
This transistor operates as a linear amplifying device in Class-A or AB small-signal stages, with verified hFE linearity across IC = 0.1 mA to 2 mA and guaranteed noise figure ≤10 dB at 1 kHz with RG = 10 kΩ. Its VCEO = 50 V and VCBO = 60 V support operation in AM RF amplifier input stages and preamplifier rails up to ±24 V supply.
The S-Mini package enables high-density placement in audio front-end modules and automotive cabin control units, while its 12 mg mass and FR4-mounted derating curve (PC = 200 mW at Ta = 25 °C, derated to zero at Ta = 125 °C) define thermal design boundaries for continuous DC biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; sets safe operating range for audio output coupling and AM detector stages. |
| hFE (GR grade) | 200–400 - DC current gain range at VCE = 6 V, IC = 2 mA; ensures predictable bias stability in discrete gain blocks. |
| NF | 1 dB (typ.), ≤10 dB (max) - Noise figure at VCE = 6 V, IC = 0.1 mA, f = 1 kHz, RG = 10 kΩ; critical for low-noise microphone preamps. |
| fT | 80 MHz (typ.) - Transition frequency at VCE = 10 V, IC = 1 mA; supports stable amplification up to mid-AM band (1.6 MHz). |
| PC (Ta = 25 °C) | 200 mW - Maximum collector power dissipation on standard FR4 board; defines thermal headroom for continuous 100 mA operation. |
| hFE linearity | 0.95 (typ.) - Ratio hFE(IC=0.1 mA)/hFE(IC=2 mA); minimizes harmonic distortion in linear amplifiers. |
Pinout & Package
S-Mini package: surface-mount, 3-pin plastic molded case (12 mg typical weight), footprint compatible with JEDEC TO-236AB outline; terminals arranged linearly with 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires series resistor for bias stability in fixed-current or voltage-divider configurations. |
| 2 | Emitter | Common reference terminal; connected to ground or negative rail in common-emitter amplifiers. |
| 3 | Collector | Output current sink; routed to load resistor or transformer primary in single-ended audio stages. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including cabin audio systems and body control modules requiring extended temperature cycling and humidity resistance. |
| High hFE linearity | 0.95 typ. ratio ensures minimal gain compression and THD < 0.5% in 1 kHz audio preamplifiers. |
| Low noise figure | 1 dB typ. at 1 kHz enables use in electret microphone biasing and analog sensor signal conditioning without added op-amp stages. |
| Complementary pairing | Matched with 2SA1162 PNP for push-pull output stages in battery-powered portable audio devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN small-signal amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SC2712-Y,LXHF | hFE = 120–240 (Y grade); lower gain range, tighter tolerance at low IC. | Better suited for high-linearity, low-distortion feedback amplifiers where gain stability > absolute gain matters. | Select when hFE consistency at IC < 1 mA is prioritized over maximum gain. |
| BC847BW | hFE = 200–450 (SOT-323), VCEO = 45 V, NF = 4.5 dB (typ.), no AEC-Q101 qualification. | Limited to industrial/commercial audio; not validated for automotive temperature or lifetime stress testing. | Choose for cost-sensitive non-automotive designs where SOT-323 footprint is preferred and AEC-Q101 is unnecessary. |
Compared with 2SC2712-Y,LXHF and BC847BW, the 2SC2712-GR,LXHF delivers higher guaranteed hFE (200–400), lower noise (1 dB vs. 4.5 dB), and full AEC-Q101 compliance-making it uniquely suitable for automotive audio preamplifiers requiring both gain headroom and reliability assurance.

FAQ
What is the hFE range for 2SC2712-GR,LXHF?
The 2SC2712-GR,LXHF has a guaranteed DC current gain (hFE) range of 200 to 400 at VCE = 6 V and IC = 2 mA, per Toshiba's GR-grade classification. This range is confirmed in the official datasheet Rev.8.0.A, Section 6, Note 5. The 2SC2712-GR,LXHF's hFE linearity ratio of 0.95 (typ.) further ensures consistent gain behavior across operating currents, making it suitable for precision analog amplifier designs.
Is 2SC2712-GR,LXHF qualified for automotive applications?
Yes, 2SC2712-GR,LXHF is explicitly AEC-Q101 qualified, as documented in the "Orderable part number" table (Section 4) of the Toshiba datasheet Rev.8.0.A. This qualification covers temperature cycling, humidity testing, and mechanical stress validation required for automotive cabin electronics. The 2SC2712-GR,LXHF is designated for "Automotive Use" in Toshiba's ordering matrix, distinguishing it from general-purpose variants like 2SC2712-O,LXHF.
What is the noise figure specification for 2SC2712-GR,LXHF?
The 2SC2712-GR,LXHF has a typical noise figure (NF) of 1 dB and a maximum of 10 dB, measured at VCE = 6 V, IC = 0.1 mA, f = 1 kHz, and RG = 10 kΩ (Section 6, Table). This low-noise performance is validated across the GR-grade population and makes the 2SC2712-GR,LXHF appropriate for microphone preamplifiers and other sensitive analog signal paths where SNR preservation is critical.
What package type does 2SC2712-GR,LXHF use?
The 2SC2712-GR,LXHF uses the S-Mini package-a surface-mount, 3-pin plastic molded case conforming to JEDEC TO-236AB outline. Its dimensions, pin assignment (1: Base, 2: Emitter, 3: Collector), and 12 mg typical weight are specified in Toshiba's Package Dimensions drawing (Rev.8.0.A, Page 6). The S-Mini footprint supports high-density PCB layouts in space-constrained audio modules.
How does 2SC2712-GR,LXHF differ from 2SC2712-BL,LXHF?
The 2SC2712-GR,LXHF and 2SC2712-BL,LXHF share identical package, absolute ratings, and AEC-Q101 qualification, but differ in hFE grading: GR = 200–400, BL = 350–700 (Section 6, Note 5). The 2SC2712-BL,LXHF offers higher gain and wider spread, while the 2SC2712-GR,LXHF provides tighter hFE distribution and superior linearity (0.95 vs. unspecified for BL), making it preferable for distortion-sensitive linear amplifiers.
