Product details
Overview
2SC2712-Y,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 = 120–240, NF = 1 dB (typ.), and AEC-Q101 qualification for automotive use.
For engineers reviewing the 2SC2712-Y,LXHF datasheet, 2SC2712-Y,LXHF pinout, 2SC2712-Y,LXHF application, or 2SC2712-Y,LXHF equivalent, key selection criteria include hFE linearity (0.95 typ.), low-noise performance at 1 kHz, S-Mini package compatibility, and automotive-grade reliability validation per AEC-Q101.
Technical Context
This NPN transistor operates in linear amplification mode with DC current gain specified across IC = 2 mA (hFE = 120–240), excellent hFE linearity confirmed by hFE(IC=0.1 mA)/hFE(IC=2 mA) = 0.95 (typ.), and low noise figure of 1 dB (typ.) at f = 1 kHz with RG = 10 kΩ.
It supports collector-emitter saturation voltage ≤ 0.25 V at IC = 100 mA/IB = 10 mA, transition frequency fT = 80 MHz (typ.), and is rated for continuous operation up to Tj = 150 °C with derating guidance provided for thermal management on FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V and 48 V audio supply rails. |
| IC(max) | 150 mA - Continuous DC collector current limit; supports medium-power preamplifier and driver stage loads. |
| hFE Range | 120–240 - Tight DC current gain bin (Y grade); ensures predictable biasing stability in Class-A amplifier designs. |
| NF | 1 dB (typ.) - Low noise figure at 1 kHz with 10 kΩ source resistance; critical for high-fidelity audio front-end amplification. |
| fT | 80 MHz (typ.) - Transition frequency; confirms usable bandwidth beyond audio spectrum into low RF ranges. |

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-O,LXHF | hFE = 70–140 (O grade); lower gain bin with wider spread; identical package, voltage, and noise specs. | Suitable for cost-sensitive general-purpose amplifiers where tighter hFE tolerance is not required. | Select when design allows looser bias point stability and lower gain margin is acceptable. |
| MMBT2222ALT1G | hFE = 100–300 (at IC = 10 mA); VCEO = 40 V; NF = 4 dB (typ.); SOT-23 package; RoHS-compliant. | Not AEC-Q101 qualified; limited to commercial temperature range (−55 °C to +150 °C). | Choose for non-automotive, space-constrained PCBs where 40 V VCEO suffices and AEC qualification is unnecessary. |

Is 2SC2712-Y,LXHF qualified for automotive applications?
Yes, the 2SC2712-Y,LXHF is explicitly AEC-Q101 qualified, as confirmed in Toshiba's orderable part number table. It meets stress test requirements for temperature cycling, humidity, mechanical shock, and high-temperature operating life, making it suitable for under-hood and cabin electronics where the 2SC2712-Y,LXHF operates within −40 °C to +125 °C ambient conditions.
What is the noise performance of 2SC2712-Y,LXHF at audio frequencies?
The 2SC2712-Y,LXHF delivers a typical noise figure of 1 dB at 1 kHz with RG = 10 kΩ, and a maximum of 10 dB. This low-noise characteristic is validated under standard test conditions (VCE = 6 V, IC = 0.1 mA) and makes the 2SC2712-Y,LXHF especially effective in microphone preamplifiers and high-fidelity audio signal paths.
What package does 2SC2712-Y,LXHF use, and what are its dimensions?
The 2SC2712-Y,LXHF uses the S-Mini (JEDEC TO-236AB) package: a 3-pin surface-mount outline measuring 1.6 mm × 2.9 mm with 0.95 mm height and 12 mg typical weight. Pin 1 is Base, Pin 2 is Emitter, and Pin 3 is Collector - matching industry-standard SOT-23 footprints but with distinct internal leadframe geometry.
How does 2SC2712-Y,LXHF compare to its complementary PNP counterpart?
The 2SC2712-Y,LXHF is designed as a complementary pair to the 2SA1162 PNP transistor. Both share matched thermal characteristics, voltage ratings, and packaging, enabling balanced push-pull and differential amplifier topologies. The 2SC2712-Y,LXHF's hFE linearity (0.95 typ.) aligns closely with the 2SA1162's behavior, ensuring symmetrical gain response when used together in the same circuit.
