Product details
Overview
2SC4116-Y,LF 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 = 120–240 (Y-grade), NF = 1 dB (typ.), and operates in USM package. It is AEC-Q101 qualified for automotive applications.
For engineers reviewing the 2SC4116-Y,LF datasheet, 2SC4116-Y,LF pinout, 2SC4116-Y,LF application, or 2SC4116-Y,LF equivalent, key selection criteria include hFE linearity (0.95 typ.), low-noise performance at 1 kHz, complementary pairing with 2SA1586, and USM footprint compatibility in space-constrained analog signal paths.
Technical Context
This NPN transistor supports linear amplification in Class-A and AB audio stages with verified hFE linearity across IC = 0.1 mA to 2 mA. Its low noise figure (1 dB typ. at RG = 10 kΩ, f = 1 kHz) and high VCEO rating enable stable operation in AM RF front-ends and preamplifier gain blocks.
The device features a single-die silicon epitaxial structure with defined absolute maximum ratings: PC = 200 mW on FR4 board, Tj(max) = 125 °C, and VEBO = 5 V. Its fT = 80 MHz (typ.) and Cob = 2.0 pF support bandwidth-limited low-frequency signal conditioning without parasitic oscillation risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Supports rail voltages up to ±24 V in discrete amplifier designs without saturation risk. |
| IC(max) | 150 mA - Enables drive capability for medium-power speaker drivers or line-level output stages. |
| hFE Range | 120–240 (Y-grade) - Ensures predictable DC bias stability in emitter-follower and common-emitter configurations. |
| NF | 1 dB (typ.) at 1 kHz - Meets low-noise requirements for microphone preamps and audio signal chains. |
| fT | 80 MHz (typ.) - Provides sufficient gain-bandwidth for AM IF amplifiers and baseband audio filtering. |
| Cob | 2.0 pF (typ.) - Minimizes Miller effect in high-gain CE stages operating below 10 MHz. |
| Package | USM - 3-pin ultra-small molded package (6.0 mg) compatible with 0.65 mm pitch PCB layouts. |
Pinout & Package
2SC4116-Y,LF uses the USM (Ultra Small Mold) surface-mount package: 1.2 × 0.8 × 0.5 mm, 3-terminal SOT-323-compatible outline. Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires series resistor (typically 10–100 kΩ) for stable biasing in linear mode. |
| 2 | Emitter | Common reference terminal; connected to ground or emitter degeneration resistor in CE/CC topologies. |
| 3 | Collector | Output current sink; routed to load resistor or next-stage input with minimal trace inductance for noise control. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive ambient temperature range (−40 °C to +125 °C junction) and thermal cycling reliability. |
| hFE linearity ratio | hFE(IC=0.1 mA)/hFE(IC=2 mA) = 0.95 (typ.) - Reduces harmonic distortion in small-signal amplification. |
| Complementary pairing | Matched electrical symmetry with 2SA1586 PNP - enables push-pull output stages without external balancing. |
| Low-noise operation | NF = 1 dB (typ.) at 1 kHz - eliminates need for additional noise-filtering components in sensitive analog inputs. |
Applications
| AM Radio Front-End Amplifier | Automotive Cabin Audio Preamp |
|---|---|
Use Scenario: Amplifies weak AM band signals (530–1710 kHz) after antenna coupling and before mixer stage. IC Role / Device Role / Timing Role: NPN small-signal amplifier in common-emitter configuration with tuned collector load. Use Value: High VCEO (50 V) withstands transient spikes from antenna coupling; low NF preserves SNR in weak-signal reception. | Use Scenario: Boosts microphone or line-level audio signals in vehicle infotainment head units before ADC sampling. IC Role / Device Role / Timing Role: Low-noise voltage amplifier in Class-A bias configuration with emitter degeneration. Use Value: AEC-Q101 qualification ensures operation across −40 °C to +105 °C ambient; hFE linearity minimizes THD in voice-band amplification. |
| Portable Audio Output Driver | Industrial Sensor Signal Conditioning |
Use Scenario: Drives 32 Ω headphones or low-impedance speakers in battery-powered portable devices. IC Role / Device Role / Timing Role: Emitter-follower output buffer providing current gain while maintaining voltage fidelity. Use Value: IC(max) = 150 mA supports peak headphone currents; USM package saves board space in compact enclosures. | Use Scenario: Amplifies millivolt-level outputs from thermocouples or strain gauges in PLC analog input modules. IC Role / Device Role / Timing Role: DC-coupled transimpedance or differential pair amplifier with precision bias network. Use Value: Stable hFE over temperature ensures consistent gain calibration; low ICBO (<0.1 µA) prevents offset drift in high-impedance sensor nodes. |
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 |
|---|---|---|---|
| 2SC4617-Y,LF | VCEO = 60 V, hFE = 120–270, same USM package, fT = 180 MHz (typ.) | Higher fT supports wider bandwidth; not AEC-Q101 qualified | Select when extended RF response is required and automotive qualification is unnecessary. |
| MMBT3904LT1G | VCEO = 40 V, hFE = 100–300, SOT-23 package, NF = 5 dB (typ.) | Lower VCEO and higher noise limit use in low-voltage, non-automotive systems | Choose for cost-sensitive consumer electronics where AEC-Q101 and sub-1-dB NF are not mandatory. |
Compared with 2SC4116-Y,LF, 2SC4617-Y,LF offers higher frequency capability but lacks automotive qualification, while MMBT3904LT1G provides broader hFE distribution in a widely available footprint but sacrifices noise performance and voltage margin.

FAQ
What is the hFE classification for 2SC4116-Y,LF?
The "Y" suffix in 2SC4116-Y,LF denotes hFE = 120–240 at VCE = 6 V and IC = 2 mA. This grade ensures tighter DC current gain consistency than the O-grade (70–140) and supports repeatable bias point design in production amplifiers. The 2SC4116-Y,LF maintains this specification across its qualified operating temperature range.
Is 2SC4116-Y,LF RoHS compliant?
Yes, the "LF" suffix in 2SC4116-Y,LF indicates lead-free termination and RoHS compliance per EU Directive 2011/65/EU. The device uses matte tin plating on terminals and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), enabling standard reflow assembly without special handling. 2SC4116-Y,LF documentation confirms full compliance with restricted substance limits.
What is the maximum power dissipation for 2SC4116-Y,LF?
The 2SC4116-Y,LF has a rated collector power dissipation (PC) of 200 mW when mounted on a 25.4 mm × 25.4 mm × 1.6 mm FR4 board with specified copper pad area. Derating is required above Ta = 25 °C at 2.0 mW/°C, reaching zero dissipation at 125 °C ambient. This limit applies directly to the 2SC4116-Y,LF in its USM package under standard JEDEC test conditions.
Does 2SC4116-Y,LF have a complementary PNP transistor?
Yes, the 2SC4116-Y,LF is explicitly designed as complementary to the 2SA1586 PNP transistor. Both share matched hFE ranges, VCEO/VEBO ratings, and USM packaging, enabling symmetrical push-pull output stages without external gain trimming. This pairing is documented in Toshiba's official 2SC4116 datasheet Rev.7.0.A and confirmed for the 2SC4116-Y,LF variant.
What is the noise figure specification for 2SC4116-Y,LF?
The 2SC4116-Y,LF has a typical noise figure (NF) of 1 dB at VCE = 6 V, IC = 0.1 mA, f = 1 kHz, and RG = 10 kΩ, with a maximum of 10 dB. This low-noise performance is validated per JEITA ED-4701 test methods and makes the 2SC4116-Y,LF suitable for microphone preamplifiers and other signal-chain stages where SNR preservation is critical.
