Product details
Overview
2SC4116-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 (Y-grade), NF = 1 dB (typ.), and AEC-Q101 qualification for automotive use. It operates in general-purpose analog signal amplification with excellent hFE linearity and low noise in compact USM package.
For engineers reviewing the 2SC4116-Y,LXHF datasheet, 2SC4116-Y,LXHF pinout, 2SC4116-Y,LXHF application, or 2SC4116-Y,LXHF equivalent, key selection criteria include its AEC-Q101 qualification status, Y-grade hFE binning (120–240), USM package pin assignment (1=Base, 2=Emitter, 3=Collector), and suitability for AM/audio amplifier biasing where low-noise linear gain is required.
Technical Context
This transistor employs epitaxial base construction to achieve high voltage tolerance (VCBO = 60 V) and stable DC current gain across collector currents from 0.1 mA to 100 mA. Its hFE linearity-quantified as hFE(IC = 0.1 mA)/hFE(IC = 2 mA) = 0.95 (typ.)-supports consistent small-signal amplification without gain compression in Class-A audio preamp stages.
Noise performance is optimized for audio band operation: NF = 1 dB (typ.) at f = 1 kHz, RG = 10 kΩ, VCE = 6 V, IC = 0.1 mA, enabling clean signal amplification in sensitive receiver front-ends and microphone preamplifiers where SNR preservation is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Supports rail voltages up to ±24 V in single-supply audio amplifier designs without saturation risk. |
| IC(max) | 150 mA - Enables driving medium-impedance loads (e.g., 330 Ω collector load) in discrete gain stages. |
| hFE (Y-grade) | 120–240 - Tight DC current gain bin ensures predictable bias point stability in production amplifier circuits. |
| NF (typ.) | 1 dB @ 1 kHz - Meets low-noise requirements for microphone preamps and AM detector stages. |
| fT | 80 MHz - Sufficient bandwidth for audio and low-IF AM signal amplification without phase distortion. |
| Cob | 3.5 pF @ VCB = 10 V - Minimizes Miller effect in common-emitter configurations up to 1 MHz. |
| PC | 200 mW @ Ta = 25°C on FR4 board - Defines thermal derating envelope for surface-mount placement in dense PCB layouts. |
Pinout & Package
Package: USM (Ultra Small Mold), 3-pin surface-mount, 1.2 × 0.8 × 0.5 mm, 6.0 mg typical weight. Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Current-controlled input node | Accepts bias current to set operating point; requires series resistor for stable DC feedback in fixed-bias or emitter-degenerated topologies. |
| 2 (Emitter) | Common reference terminal | Connected to ground or emitter resistor; determines AC signal reference and sets local feedback impedance in common-emitter amplifiers. |
| 3 (Collector) | Output current sink | Delivers amplified output current to load or next stage; must be decoupled from supply rail to prevent oscillation in high-gain configurations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive ambient temperature range (−40°C to +125°C junction) and vibration/thermal cycling stress per JESD22 standards. |
| High hFE linearity | hFE ratio of 0.95 (typ.) between 0.1 mA and 2 mA collector currents enables uniform gain across audio signal swing without harmonic distortion. |
| Low noise figure | 1 dB (typ.) at 1 kHz allows use in first-stage amplification of weak signals (e.g., ceramic cartridge phono inputs) without degrading SNR. |
| Complementary pair | Designed as NPN counterpart to 2SA1586 PNP transistor, enabling matched push-pull output stages in Class-AB audio amplifiers. |
Applications
| AM Radio Intermediate Frequency Amplifier | Automotive Cabin Audio Preamp |

Use Value: hFE linearity (0.95 ratio) maintains gain accuracy across temperature-induced signal drift; 50 V VCEO accommodates industrial supply rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN bipolar transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SC4116-O,LXHF | O-grade hFE = 70–140 (vs. Y-grade 120–240); otherwise identical electrical specs and AEC-Q101 qualification. | Suitable for cost-sensitive general-purpose amplifiers where tighter hFE control is not required. | Select 2SC4116-O,LXHF when circuit design tolerates wider hFE variation and lower minimum gain. |
| 2SC4081-Y,LF | Same USM package, but VCEO = 32 V (vs. 50 V); hFE = 120–240; no AEC-Q101 documentation confirmed. | Limited to ≤24 V supply systems; not validated for automotive temperature cycling or reliability testing. | Choose 2SC4081-Y,LF only for non-automotive, low-voltage consumer audio where 50 V headroom is unnecessary. |
Compared with 2SC4116-O,LXHF and 2SC4081-Y,LF, the 2SC4116-Y,LXHF uniquely combines Y-grade hFE consistency, 50 V breakdown margin, and AEC-Q101 validation-making it the only option among the three qualified for automotive cabin audio signal paths requiring both reliability and linearity.

FAQ
What does the "Y" suffix indicate in 2SC4116-Y,LXHF?
The "Y" suffix denotes the hFE gain bin classification: 2SC4116-Y,LXHF has a guaranteed DC current gain range of 120 to 240 at VCE = 6 V and IC = 2 mA. This tighter binning improves predictability in bias-critical amplifier designs compared to the broader O-grade (70–140) or BL-grade (350–700) variants of the same 2SC4116 family.
Is 2SC4116-Y,LXHF qualified for automotive applications?
Yes, 2SC4116-Y,LXHF is explicitly AEC-Q101 qualified per Toshiba's orderable part number list and datasheet Rev.7.0.A. It meets stress test requirements for temperature cycling, humidity, mechanical shock, and high-temperature operating life-making it suitable for under-hood and cabin audio systems operating from −40°C to +125°C junction temperature.
What is the pin configuration of 2SC4116-Y,LXHF in the USM package?
The 2SC4116-Y,LXHF uses a 3-pin USM (Ultra Small Mold) package with standardized pinout: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This arrangement is consistent across all 2SC4116 variants and matches industry-standard SOT-323 orientation when viewed from the top with marking side up and pin 1 at bottom-left.
How does the noise figure of 2SC4116-Y,LXHF compare to other general-purpose transistors?
2SC4116-Y,LXHF achieves a typical noise figure of 1 dB at 1 kHz (VCE = 6 V, IC = 0.1 mA, RG = 10 kΩ), which is significantly lower than standard general-purpose transistors like BC547 (NF ≈ 10 dB). This makes the 2SC4116-Y,LXHF appropriate for first-stage amplification where signal integrity is critical, such as electret microphone preamps or AM detector stages.
Can 2SC4116-Y,LXHF be used as a direct replacement for 2SC4116-Y without the LXHF suffix?
No-2SC4116-Y,LXHF includes lead-free (LF) and halogen-free (HF) compliance per RoHS and JEDEC standards, whereas 2SC4116-Y lacks those environmental certifications. Electrically and mechanically identical, the LXHF variant is required for modern electronics manufacturing with strict material content controls; substitution requires verification of end-equipment compliance requirements.
