Product details

Overview

15C01SS-TL-E from onsemi is a low-V_CE(sat) NPN bipolar transistor in SSFP (SC-81) package, rated for 15 V V_CEO, 600 mA I_C, and 330 MHz f_T, optimized for low-frequency amplification and muting circuits in compact audio and signal routing applications.

For engineers reviewing the 15C01SS-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include its 0.58 Ω typical R_CE(sat) at I_C=0.7A/ I_B=35mA, ultrasmall 1.4×0.8×0.6 mm footprint, and verified h_FE range of 300–800 at V_CE=2V/I_C=10mA.

Technical Context

This device operates as a single NPN switching and amplification transistor with a maximum V_CEO of 15 V and V_CB0 of 20 V, supporting reliable cutoff and saturation under low-frequency signal conditions. Its 330 MHz gain-bandwidth product enables stable small-signal amplification up to audio band edges without oscillation risk.

Designed for surface-mount use on glass epoxy PCBs (20×30×1.6 mm), it delivers 200 mW power dissipation with thermal limits defined by T_j ≤ 150 °C and T_stg from –55 to +150 °C - consistent with industrial-grade discrete handling requirements.

Key Specifications

V_CEO	15 V - Maximum safe collector-emitter voltage before breakdown; defines rail compatibility in low-voltage analog switches.
I_C	600 mA continuous - Sustained current-handling capability for muting paths and driver stages in portable audio ICs.
R_CE(sat)	0.58 Ω typ @ I_C=0.7A/I_B
f_T	330 MHz - Bandwidth limit for small-signal amplification; supports full audio spectrum (20 Hz–20 kHz) with ample margin.
h_FE	300–800 @ V_CE=2V/I_C=10mA - Stable DC current gain range ensuring predictable base drive sizing in linear and switching modes.
C_ob	3.2 pF @ V_CB=10V/f=1MHz - Low output capacitance minimizing high-frequency loading in amplifier feedback networks.
t_on/t_f	30 ns / 40 ns - Fast switching transitions suitable for digital control of analog signal paths without audible artifacts.

Pinout & Package

Package: SSFP (SC-81), ultrasmall flat-lead plastic package measuring 1.4 mm × 0.8 mm × 0.6 mm, designed for high-density PCB layouts and automated placement.

Pin/Terminal	Circuit Role	Design Meaning

2	Emitter	Reference node for current flow; internally connected to substrate ground plane in SC-81 layout; must be routed with low-inductance path.
3	Collector	Output terminal carrying load current; electrically isolated from package pad; connects to signal path being muted or amplified.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN switching and amplification applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSV15C01SS-TL-E	Same die, AEC-Q101 qualified; identical electrical specs but automotive-grade reliability screening.	Required for automotive infotainment mute circuits; not needed for consumer audio.	Select only if automotive qualification is mandated; otherwise 15C01SS-TL-E suffices.
DXT7050Z-7	SOT-523 package (1.6×0.8×0.55 mm); V_CEO=12 V, I_C=500 mA, R_CE(sat)=0.8 Ω - slightly larger footprint and higher saturation resistance.	Acceptable where board space allows minor increase and 12 V rail is used.	Use when SSFP tooling is unavailable; verify layout clearance for SOT-523 pad geometry.

Compared with NSV15C01SS-TL-E and DXT7050Z-7, the 15C01SS-TL-E offers the smallest footprint and lowest R_CE(sat) among these three, making it optimal for space-constrained consumer audio designs where automotive qualification is unnecessary.

FAQ

What is the maximum collector-emitter voltage rating for the 15C01SS-TL-E?

The 15C01SS-TL-E has a maximum collector-emitter voltage (V_CEO) rating of 15 V. This value is specified under standard test conditions (I_C = 1 mA, R_BE = ∞) and represents the upper limit before breakdown occurs. Exceeding this voltage risks permanent damage, and operation should remain within recommended conditions (≤15 V) for reliable performance in audio muting and amplification roles.

Does the 15C01SS-TL-E support high-frequency signal amplification?

The 15C01SS-TL-E has a gain-bandwidth product (f_T) of 330 MHz, which supports stable small-signal amplification well beyond the audio band (20 Hz–20 kHz). However, its primary design focus is low-frequency applications like muting and pre-amplification; for RF or wideband applications above 10 MHz, dedicated RF transistors with optimized noise figure and S-parameters are recommended instead of the 15C01SS-TL-E.

What is the pin configuration and package type of the 15C01SS-TL-E?

The 15C01SS-TL-E uses the SSFP (SC-81) package with three terminals: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. Its dimensions are 1.4 mm × 0.8 mm × 0.6 mm, and it features flat leads for reflow soldering. The marking "YP" appears on the top surface, and the device is supplied in embossed tape/reel format (8,000 pcs./reel) as indicated by the "-TL-E" suffix in 15C01SS-TL-E.

Is the 15C01SS-TL-E suitable for new designs despite its discontinued status?

No - the 15C01SS-TL-E is officially marked "DISCONTINUED" and "NOT RECOMMENDED FOR NEW DESIGN" in onsemi's documentation. While Aetrix Electronics maintains legacy inventory and supports existing production, new designs should consider alternatives like NSV15C01SS-TL-E (automotive-qualified) or DXT7050Z-7 (SOT-523 variant) to ensure long-term supply chain viability and avoid obsolescence risk in the 15C01SS-TL-E.

What is the typical collector-to-emitter saturation resistance of the 15C01SS-TL-E?

The typical collector-to-emitter saturation resistance (R_CE(sat)) of the 15C01SS-TL-E is 0.58 Ω, measured at I_C = 0.7 A and I_B = 35 mA. This low value directly translates to minimal voltage drop (<300 mV) across the device in saturated switching mode, making the 15C01SS-TL-E especially effective in low-loss analog signal gating and muting applications where signal fidelity is critical.
