Product details
Overview
2SC4117-GR,LF from Toshiba Electronic Devices & Storage Corporation is a silicon NPN epitaxial transistor designed for audio-frequency general-purpose amplifier applications. It delivers VCEO = 120 V, hFE = 200–400 (GR grade), NF = 1 dB (typ.), fT = 100 MHz, and operates in SC-70 (JEITA) / 2-2E1A package. It is AEC-Q101 qualified and complementary to 2SA1587 for push-pull audio stages.
For engineers reviewing the 2SC4117-GR,LF datasheet, 2SC4117-GR,LF pinout, 2SC4117-GR,LF application, or 2SC4117-GR,LF equivalent, this discrete NPN transistor is selected for low-noise preamplifier gain stages, line-level audio buffering, and automotive infotainment signal conditioning where high hFE linearity and stable small-signal performance are critical.
Technical Context
This transistor employs PCT (Planar Collector Technology) processing for improved thermal stability and consistent hFE linearity across collector current range. Its 120 V VCEO rating enables use in higher-voltage audio rails, while the 1 dB typical noise figure supports high-fidelity analog front-end design at 1 kHz with 10 kΩ source impedance.
The GR grade specifies hFE = 200–400 at VCE = 6 V, IC = 2 mA, and its 100 MHz fT ensures adequate bandwidth for wideband audio amplification up to ~20 kHz with margin. Cob = 3.0 pF minimizes Miller effect in common-emitter configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 120 V - Supports operation in 48 V and 96 V audio supply rails without breakdown risk |
| hFE (GR grade) | 200–400 - Enables predictable DC biasing and gain control in Class-A preamp stages |
| NF (typ.) | 1 dB @ 1 kHz - Minimizes added noise in microphone or phono preamplifier input stages |
| fT | 100 MHz - Provides >5× bandwidth margin over 20 kHz audio band for stable gain |
| Cob | 3.0 pF - Limits high-frequency feedback and stabilizes common-emitter gain at 10 kHz+ |
| PC (FR4 board) | 200 mW - Allows 100 mA IC handling at Ta ≤ 25°C with standard PCB copper area |
| VEBO | 5 V - Constrains base drive voltage swing to prevent emitter-base junction damage |
Pinout & Package
Package: SC-70 (JEITA) / Toshiba 2-2E1A - surface-mount, 3-terminal plastic package (0.006 g typ., footprint compatible with SOT-323 but smaller lead pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Emitter (E) | Current sink terminal | Connected to ground or low-impedance return path; sets DC bias reference point |
| Base (B) | Control input | Receives forward-biased current to modulate collector current; requires current-limiting resistor |
| Collector (C) | Output current source | Drives load or next stage; voltage swing limited by VCEO = 120 V and PC derating |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature cycling, humidity, and mechanical stress per Rev G requirements |
| High hFE linearity | hFE(0.1 mA)/hFE(2 mA) = 0.95 typ. - Ensures minimal gain compression in varying signal amplitude conditions |
| Low noise figure | 1 dB typ. @ 1 kHz - Preserves SNR in sensitive analog signal chains before ADC or DSP stages |
| Complementary pairing | Matched with 2SA1587 (PNP) - Enables symmetrical push-pull output stages with balanced distortion |
| Small footprint | SC-70 package - Saves board space in multi-channel audio modules and compact infotainment head units |
Applications
| Audio Preamp Stage | Automotive Line Driver |
|---|---|
Use Scenario: Low-level analog signal amplification prior to ADC in car radio tuner or digital audio processor. IC Role / Device Role / Timing Role: NPN small-signal amplifier in common-emitter configuration with emitter degeneration. Use Value: 1 dB NF preserves weak RF/IF signal integrity; 120 V VCEO accommodates transient-suppressed 48 V supply rails. |
Use Scenario: Driving balanced/unbalanced audio lines between head unit and amplifier in vehicle cabin networks. IC Role / Device Role / Timing Role: Voltage follower or gain-of-2 buffer with low output impedance. Use Value: hFE linearity ensures flat frequency response; SC-70 allows dense channel packing on multi-zone audio PCBs. |

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 |
|---|---|---|---|
| 2SC4081-GR,LF | VCEO = 60 V, hFE = 200–400, NF = 1.5 dB (typ.), same SC-70 package | Limited to ≤24 V supply rails; lower voltage headroom reduces transient immunity | Select when cost sensitivity outweighs need for 120 V rating and automotive-grade noise floor |
| MMBT5551-7-F | VCEO = 160 V, hFE = 80–250, NF = 5 dB (max), SOT-23 package | Broad hFE spread increases production binning complexity; higher noise limits low-level use | Choose for higher-voltage switching or digital logic interface where gain linearity is secondary |
Compared with 2SC4117-GR,LF, the 2SC4081-GR,LF trades voltage margin for cost, while MMBT5551-7-F sacrifices noise and hFE consistency for wider voltage tolerance-making 2SC4117-GR,LF optimal for precision audio gain where both low noise and linearity are required.

FAQ
What is the hFE grade designation for 2SC4117-GR,LF?
The "GR" suffix in 2SC4117-GR,LF indicates the hFE bin: 200–400 at VCE = 6 V and IC = 2 mA. This grade ensures tighter DC gain consistency for production audio amplifier calibration. The alternative "BL" grade offers 350–700 hFE. Both grades share identical electrical characteristics otherwise, including noise figure and voltage ratings.
Is 2SC4117-GR,LF suitable for automotive applications?
Yes, 2SC4117-GR,LF is AEC-Q101 qualified per Note 1 in the official Toshiba datasheet, confirming compliance with stress tests for temperature cycling, humidity, mechanical shock, and ESD. It is rated for Tj = 150 °C and Tstg = −55 to +150 °C, making it appropriate for under-dash infotainment and amplifier modules.
What is the maximum collector power dissipation for 2SC4117-GR,LF?
2SC4117-GR,LF has a maximum collector power dissipation (PC) of 200 mW when mounted on a standard FR4 board (25.4 mm × 25.4 mm × 1.6 mm with three 0.5 mm² Cu pads). At ambient temperatures above 25 °C, derating applies per the Pc–Ta curve in the Toshiba datasheet, reaching 100 mW at Ta = 100 °C.
Does 2SC4117-GR,LF have a complementary PNP device?
Yes, 2SC4117-GR,LF is explicitly designated as complementary to 2SA1587 (PNP), also offered in SC-70 package with matched VCEO = 120 V, hFE grading, and noise performance. This pairing enables symmetrical Class-AB output stages and differential amplifier topologies in high-fidelity audio designs.
What is the noise figure specification for 2SC4117-GR,LF?
The noise figure for 2SC4117-GR,LF is 1 dB (typical) and 10 dB (maximum) at VCE = 6 V, IC = 0.1 mA, f = 1 kHz, and RG = 10 kΩ. This low-noise performance is validated in Toshiba's Electrical Characteristics table and makes the device suitable for first-stage amplification of microvolt-level signals in phono or condenser mic preamps.
