Product details
Overview
2SC2712-BL,LXHF from Toshiba Electronic Devices & Storage Corporation is a silicon NPN epitaxial bipolar transistor designed for low-frequency and audio-frequency amplifier stages. It delivers VCEO = 50 V, IC(max) = 150 mA, hFE = 350–700 (BL grade), NF = 1 dB (typ.), and operates in S-Mini package with 1–2–3 pinout (B–E–C). It is AEC-Q101 qualified for automotive use.
For engineers reviewing the 2SC2712-BL,LXHF datasheet, 2SC2712-BL,LXHF pinout, 2SC2712-BL,LXHF application, or 2SC2712-BL,LXHF equivalent, key selection criteria include hFE linearity (0.95 typ.), low-noise performance at 1 kHz, complementary pairing with 2SA1162, and automotive-grade reliability validation under AEC-Q101.
Technical Context
This transistor uses epitaxial base construction to achieve high hFE linearity and stable gain across collector current (IC = 0.1 mA to 2 mA). Its low noise figure (1 dB typ. at RG = 10 kΩ, f = 1 kHz) and high transition frequency (fT = 80 MHz typ.) support high-fidelity audio amplification and AM signal processing.
The device is rated for VCBO = 60 V and VCEO = 50 V, enabling use in medium-voltage analog front-ends. Its S-Mini package (12 mg, 2.9 × 2.4 × 0.9 mm) supports compact PCB layouts while maintaining thermal dissipation up to 200 mW on FR4 board (25.4 mm × 25.4 mm × 1.6 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Supports rail voltages up to ±24 V in Class-A audio stages without saturation risk. |
| hFE (BL grade) | 350–700 - Enables high-current gain stability in emitter-follower and preamp configurations. |
| NF | 1 dB (typ.) - Ensures minimal signal degradation in microphone preamps and low-level audio paths. |
| fT | 80 MHz (typ.) - Allows operation beyond audio band into AM IF stages (e.g., 455 kHz) with margin. |
| PC (on FR4) | 200 mW - Permits continuous 100 mA collector current at 2 V VCE in thermally constrained SMT layouts. |
| hFE linearity | 0.95 ([email protected] / hFE@2mA) - Reduces harmonic distortion in linear amplification applications. |
Pinout & Package
S-Mini package: ultra-compact surface-mount plastic case (2.9 × 2.4 × 0.9 mm), 3-pin, 12 mg weight, RoHS-compliant, lead-free (LXHF suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Emitter | Common reference terminal; connected to ground or emitter degeneration resistor in CE/CC topologies. |
| 3 | Collector | Output current sink; routed to load or next stage with attention to VCEO derating above 25°C. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive ambient temperature range (−40°C to +125°C) and humidity exposure per stress test requirements. |
| High hFE linearity | Enables low THD (<0.5%) in single-transistor audio preamplifiers without feedback compensation. |
| Low noise figure | Supports SNR > 80 dB in electret microphone biasing circuits at 1 kHz with 10 kΩ source impedance. |
| Complementary pairing | Direct match with 2SA1162 PNP for push-pull output stages or differential pairs in balanced amplifiers. |
Applications
| AM Radio Intermediate Frequency Amplifier | Automotive Cabin Audio Preamp |
|---|---|
Use Scenario: Amplifying 455 kHz IF signals in AM radio receivers before demodulation. IC Role / Device Role / Timing Role: NPN small-signal amplifier in tuned common-emitter configuration with LC tank load. Use Value: High fT (80 MHz) ensures gain flatness across IF bandwidth; low NF preserves weak-signal SNR. | Use Scenario: Low-noise voltage amplification of microphone or line-level inputs in vehicle infotainment head units. IC Role / Device Role / Timing Role: First-stage preamplifier with emitter degeneration for DC bias stability and THD control. Use Value: AEC-Q101 qualification guarantees operation over −40°C to +125°C junction temperature; hFE linearity minimizes distortion at varying signal levels. |
| General-Purpose Audio Amplifier | Low-Frequency Signal Buffer |
Use Scenario: Driving 10 kΩ loads in consumer audio equipment (e.g., headphone amp input stage). IC Role / Device Role / Timing Role: Common-collector (emitter-follower) buffer providing high input impedance and low output impedance. Use Value: High hFE (350–700) enables low base drive current; S-Mini footprint saves space in multi-channel designs. | Use Scenario: Isolating sensor outputs (e.g., thermistor networks) from downstream ADC input loading effects. IC Role / Device Role / Timing Role: Unity-gain voltage follower with DC-coupled input and output. Use Value: Low VCE(sat) (0.25 V max) ensures minimal offset error; 50 V VCEO accommodates wide supply rails in industrial sensor interfaces. |
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 (lower gain range); identical package, pinout, and AEC-Q101 rating. | Better suited for moderate-gain, high-linearity applications where gain variation must be minimized. | Select when consistent hFE spread (±20%) is prioritized over maximum gain. |
| BC847BL,215 | hFE = 200–450; SOT-23 package; VCEO = 45 V; not AEC-Q101 qualified. | Limited to general-purpose industrial or consumer use; unsuitable for automotive environments. | Choose only for cost-sensitive non-automotive designs where AEC-Q101 compliance is not required. |

FAQ
What does the "BL" suffix indicate in 2SC2712-BL,LXHF?
The "BL" suffix denotes the hFE gain classification: 350–700 at VCE = 6 V and IC = 2 mA. This is the highest gain bin in the 2SC2712 family, selected for applications demanding maximum current amplification without external gain staging. The 2SC2712-BL,LXHF maintains this specification while also meeting AEC-Q101 automotive qualification requirements.
Is 2SC2712-BL,LXHF pin-compatible with other 2SC2712 variants?
Yes, all 2SC2712 variants-including 2SC2712-BL,LXHF-share identical S-Mini package dimensions and 1–2–3 pinout (Base–Emitter–Collector). No PCB layout changes are needed when substituting between O/Y/GR/BL grades, provided thermal and gain requirements are verified per application. The 2SC2712-BL,LXHF retains full mechanical and electrical compatibility within the family.
Does 2SC2712-BL,LXHF support automotive applications?
Yes, 2SC2712-BL,LXHF is explicitly AEC-Q101 qualified, as confirmed in Toshiba's orderable part number table. It is rated for operation from −40°C to +125°C junction temperature and validated for humidity, thermal cycling, and mechanical shock per AEC-Q101 standards. This makes the 2SC2712-BL,LXHF suitable for under-hood and cabin audio systems in passenger vehicles.
What is the maximum collector power dissipation for 2SC2712-BL,LXHF?
The maximum collector power dissipation (PC) for 2SC2712-BL,LXHF is 200 mW when mounted on a standard 25.4 mm × 25.4 mm × 1.6 mm FR4 board with specified copper pad area. Derating is required above 25°C ambient: approximately 1.6 mW/°C reduction beyond 25°C. This value applies directly to the 2SC2712-BL,LXHF variant and is validated per Toshiba's Rev.8.0.A datasheet.
How does the noise figure of 2SC2712-BL,LXHF compare to similar transistors?
2SC2712-BL,LXHF achieves a typical noise figure of 1 dB at VCE = 6 V, IC = 0.1 mA, f = 1 kHz, and RG = 10 kΩ-matching or exceeding industry benchmarks for S-Mini packaged NPN transistors. This performance is enabled by epitaxial base design and optimized doping profiles. For low-noise preamp designs, the 2SC2712-BL,LXHF offers measurable SNR advantage over generic alternatives like BC547 or PN2222A, especially below 10 kHz.
