Product details

Overview

2SC4116-GR,LF from Toshiba Electronic Devices & Storage Corporation is a silicon NPN epitaxial bipolar transistor designed for low-frequency and audio-frequency amplifier applications. It delivers V_CEO = 50 V, I_C = 150 mA (max), h_FE = 200–400 (GR grade), and NF = 1 dB (typ.) at 1 kHz, serving as a general-purpose amplifier in AM radio front-ends and portable audio stages.

For engineers reviewing the 2SC4116-GR,LF datasheet, 2SC4116-GR,LF pinout, 2SC4116-GR,LF application, or 2SC4116-GR,LF equivalent, key selection criteria include its AEC-Q101 qualification for automotive use, USM package footprint, h_FE linearity (0.95 typ.), and low-noise performance under 10 kΩ source impedance.

Technical Context

This transistor operates as a linear amplifying device with fixed-emitter biasing capability, optimized for Class-A small-signal amplification. Its h_FE classification (GR) ensures consistent DC gain across production lots, while f_T = 80 MHz supports stable operation up to mid-audio frequencies without phase distortion.

The USM package enables high-density PCB layouts with thermal resistance R_θJA = 500°C/W (on FR4), and its complementary pairing with 2SA1586 allows push-pull stage implementation. Absolute maximum ratings are defined for both general and automotive-grade variants, with derating guidance provided per Toshiba's reliability handbook.

Key Specifications

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	V_CEO = 30 V (lower); h_FE = 200–400; same USM package	Not rated for 50 V rail systems; unsuitable for AM front-end transient tolerance	Select only when supply voltage ≤ 24 V and automotive qualification is not required

FAQ

What is the h_FE range for 2SC4116-GR,LF?

The 2SC4116-GR,LF has a guaranteed DC current gain (h_FE) range of 200 to 400 at V_CE = 6 V and I_C = 2 mA. This GR-grade binning ensures tighter gain distribution than standard O- or Y-grade variants, improving predictability in bias-critical amplifier designs. The 2SC4116-GR,LF maintains this specification across its qualified operating temperature range.

Is 2SC4116-GR,LF qualified for automotive applications?

Yes, 2SC4116-GR,LF is AEC-Q101 qualified and designated for automotive use per Toshiba's orderable part number list. It meets stress testing requirements for temperature cycling, humidity bias, and mechanical shock. The 2SC4116-GR,LF is rated for junction temperatures up to 150°C and storage temperatures from −55°C to +150°C, supporting under-hood and cabin audio deployments.

What package does 2SC4116-GR,LF use and what are its dimensions?

2SC4116-GR,LF uses the USM (Ultra Small Mold) package - a 3-pin surface-mount outline equivalent to JEDEC TO-236AB. Its dimensions are 1.8 mm × 1.5 mm × 0.8 mm (L × W × H), with pin 1 = Base, pin 2 = Emitter, pin 3 = Collector. The typical weight is 6.0 mg, and thermal resistance is specified at 500°C/W on a 25.4 mm × 25.4 mm FR4 board.

How does the noise figure of 2SC4116-GR,LF compare to similar transistors?

The 2SC4116-GR,LF achieves a typical noise figure of 1 dB at 1 kHz with R_G = 10 kΩ, significantly lower than standard small-signal transistors like MMBT4401LT1G (4 dB typ.). This performance stems from optimized epitaxial base design and low-base-resistance construction. For low-noise microphone preamps or AM detector stages, the 2SC4116-GR,LF provides measurable SNR advantage over non-optimized alternatives.

What is the complementary PNP transistor for 2SC4116-GR,LF?

The complementary PNP transistor for 2SC4116-GR,LF is the 2SA1586, also manufactured by Toshiba. Both devices share matching h_FE grading, voltage ratings, and USM packaging, enabling symmetrical push-pull or differential pair implementations. The 2SC4116-GR,LF and 2SA1586 are explicitly listed as complementary in Toshiba's official documentation and are commonly used together in Class-AB audio output stages.
