Product details

Overview

2SC6099-TL-E from onsemi is an NPN general-purpose bipolar junction transistor (BJT) in a small-outline SOT-323 (SC-70) package, rated for 50 V V_CEO, 150 mA I_C, and 200 mW P_D, commonly used in low-power switching and amplification circuits in portable electronics and signal conditioning stages.

For engineers reviewing the 2SC6099-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include DC current gain (h_FE) range at specified I_C, saturation voltage (V_CE(sat)) at defined drive conditions, transition frequency (f_T), thermal resistance (R_θJA), and guaranteed performance across industrial temperature range.

Technical Context

This device operates as a discrete current-controlled amplifier/switch with fixed emitter-base and collector-base junction structures. Its h_FE is specified at 100–320 at I_C = 2 mA and V_CE = 6 V, and f_T reaches 180 MHz at I_C = 10 mA and V_CE = 6 V, supporting RF-capable small-signal applications up to VHF band.

The 2SC6099-TL-E features a maximum V_CEO of 50 V and V_CB0 of 60 V, enabling use in 3.3 V and 5 V logic-level interface circuits where moderate breakdown margin is required. Junction-to-ambient thermal resistance is 417 °C/W under standard PCB mounting per JEDEC 51-3.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - supports operation in 3.3 V/5 V systems with headroom for transient spikes
I_C (max)	150 mA - suitable for driving LEDs, small relays, or logic-level translation loads
P_D (max)	200 mW - limits continuous dissipation without heatsinking on standard FR-4
h_FE	100–320 @ I_C = 2 mA, V_CE = 6 V - enables predictable biasing in Class-A amplifiers
f_T	180 MHz @ I_C = 10 mA, V_CE = 6 V - usable in VHF oscillator and RF preamp stages
R_θJA	417 °C/W - requires careful layout for ambient temperatures above 50 °C

Pinout & Package

2SC6099-TL-E is housed in a 3-pin SOT-323 (SC-70) plastic surface-mount package with gull-wing leads, optimized for high-density PCB layouts and automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
Emitter (E)	Current sink terminal	Connected to ground or low-impedance return path; defines reference for base bias
Base (B)	Control input	Receives current-limited drive (typically 0.1–1 mA) to saturate or cut off collector current
Collector (C)	Current source terminal	Supplies switched load current; routed away from sensitive analog traces to minimize coupling

Key Features

Feature	Design Value
High f_T	180 MHz enables stable small-signal amplification up to 100 MHz with minimal phase shift
Wide h_FE range	100–320 allows consistent gain across production lots without individual trimming
Low V_CE(sat)	0.3 V @ I_C = 50 mA, I_B = 5 mA reduces conduction loss in switching mode
SOT-323 footprint	Compatible with standard 0.65 mm pitch pick-and-place equipment and reflow profiles

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN small-signal transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC847BW,115	Same SOT-323 package; h_FE = 200–450 @ I_C = 2 mA; f_T = 250 MHz	Higher f_T and tighter h_FE binning support higher-speed digital switching	Preferred when >100 MHz switching or tighter gain control is required

Compared with BC847BW,115 and MMBT3904LT1G, the 2SC6099-TL-E offers balanced f_T, h_FE, and thermal performance in the smallest footprint, making it optimal for space-constrained, battery-sensitive designs where 180 MHz bandwidth suffices.

FAQ

What is the maximum collector-emitter voltage rating for the 2SC6099-TL-E?

The 2SC6099-TL-E has a maximum V_CEO rating of 50 V, verified per onsemi's official datasheet. This rating defines the highest voltage that can be sustained between collector and emitter with the base open, ensuring safe operation in 3.3 V and 5 V systems with transient margin. Exceeding this voltage risks avalanche breakdown and permanent device failure. The 2SC6099-TL-E must not be used in circuits where steady-state or peak V_CE exceeds 50 V.

Does the 2SC6099-TL-E support RF signal amplification?

Yes, the 2SC6099-TL-E supports RF signal amplification up to approximately 100 MHz due to its 180 MHz transition frequency (f_T) measured at I_C = 10 mA and V_CE = 6 V. It is suitable for VHF-band oscillator and preamplifier stages in low-power receivers and transmitters. However, the 2SC6099-TL-E is not characterized for noise figure or S-parameters, so system-level validation is required for critical RF links.

What is the typical DC current gain (h_FE) of the 2SC6099-TL-E at 2 mA collector current?

The 2SC6099-TL-E exhibits a typical h_FE of 200 at I_C = 2 mA and V_CE = 6 V, with a guaranteed minimum of 100 and maximum of 320 under those same conditions. This wide but bounded range allows robust bias design without individual device sorting. For stable amplifier operation, designers should verify gain stability across the full h_FE spread using worst-case analysis in the 2SC6099-TL-E circuit.

Can the 2SC6099-TL-E replace a BC547 in existing designs?

The 2SC6099-TL-E is not a direct replacement for BC547 due to differences in package (SOT-323 vs. TO-92), thermal characteristics (R_θJA = 417 °C/W vs. ~200 °C/W), and absolute maximum ratings (V_CEO = 50 V vs. 45 V). While electrical parameters overlap, the 2SC6099-TL-E requires PCB redesign for SMT assembly and thermal derating. Use of 2SC6099-TL-E in BC547-based legacy designs demands full revalidation of thermal performance and solder joint reliability.

What is the power dissipation limit of the 2SC6099-TL-E on a standard FR-4 PCB?

The 2SC6099-TL-E has a maximum power dissipation (P_D) of 200 mW at T_A = 25 °C on a standard FR-4 PCB with no copper pour. This limit decreases linearly with ambient temperature at a rate determined by its 417 °C/W junction-to-ambient thermal resistance. At 50 °C ambient, the practical P_D drops to ~150 mW. To sustain 200 mW, the 2SC6099-TL-E requires enhanced thermal relief such as thermal vias or local copper flooding.
