Product details

Overview

15C01M-TL-E from onsemi is an NPN bipolar junction transistor (BJT) optimized for low-frequency amplification and muting circuits, featuring V_CEO = 15 V, I_C = 700 mA, V_CE(sat) = 150 mV (typ.) at I_C = 200 mA / I_B = 10 mA, and h_FE = 300–800. It operates in SC-70 (MCP3) package and delivers low saturation voltage for efficient switching in compact audio and signal-path control applications.

For engineers reviewing the 15C01M-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat) performance at 200 mA drive, h_FE stability across −25°C to +75°C, SC-70 thermal dissipation (300 mW on 20×30×1.6 mm board), and Pb-free/halide-free compliance per JEDEC standards.

Technical Context

This NPN BJT employs a planar epitaxial structure with optimized base doping and geometry to achieve low V_CE(sat) and high h_FE simultaneously. Its f_T = 330 MHz enables stable operation beyond audio band while maintaining low Cob = 3.2 pF at V_CB = 10 V - critical for minimizing signal distortion in muting paths.

Designed for DC-coupled or low-frequency AC switching, it supports IC pulse ratings up to 1.4 A and withstands V_CEO = 15 V and V_CB0 = 20 V. Junction temperature is rated to 150°C, with storage range spanning −55°C to +150°C - suitable for industrial ambient conditions without derating below 75°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	15 V - maximum safe collector-emitter voltage under open-base condition; defines headroom for 12 V rail muting switches
I_C	700 mA continuous - supports audio amplifier stage biasing or speaker protection relay drivers
V_CE(sat)	150 mV typ. @ I_C=200 mA/I_B=10 mA - ensures <0.03 W conduction loss, enabling thermally constrained PCB layouts
h_FE	300–800 @ V_CE=2 V, I_C=10 mA - provides stable current gain for linear gain stages and predictable base drive sizing
f_T	330 MHz - confirms sufficient bandwidth for transient suppression and fast turn-on/turn-off (t_on=30 ns, t_f=40 ns)
C_ob	3.2 pF @ V_CB=10 V - minimizes capacitive loading on preceding stages in multi-transistor mute networks

Pinout & Package

15C01M-TL-E is housed in SC-70 (MCP3, Case 419AJ), a 3-pin ultrasmall surface-mount package measuring 2.0 × 1.25 × 0.9 mm (L × W × H), optimized for high-density audio subsystems and portable electronics.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal requiring 10 mA typical drive for full saturation; low V_BE(sat) = 0.9 V enables direct MCU GPIO interface
2	Emitter	Reference node tied to system ground or common return; internal connection to substrate for thermal path
3	Collector	Output terminal carrying load current up to 700 mA; exposed pad not present - thermal transfer via leads only

Key Features

Feature	Design Value
Low V_CE(sat)	150 mV typ. at 200 mA ensures minimal power loss and self-heating in always-on mute paths
High h_FE range	300–800 supports consistent gain across production lots without individual trimming
Ultrasmall SC-70 footprint	2.0 × 1.25 mm area reduces PCB real estate by >50% vs. SOT-23 in space-constrained earbud and hearing aid designs
Pb-free and halide-free	Complies with J-STD-609 Category 1 and RoHS Directive 2011/65/EU without derating or reliability impact

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
MMBT3904LT1G	V_CEO = 40 V, I_C = 200 mA, V_CE(sat) = 300 mV @ 50 mA - higher voltage rating but lower current and higher saturation voltage	Better suited for general-purpose logic-level switching; less optimal for 700 mA muting loads	Select when higher breakdown margin is required and load current remains ≤200 mA
DXTN07100B-7	V_CEO = 12 V, I_C = 1 A, V_CE(sat) = 120 mV @ 500 mA - tighter V_CE(sat) spec but lower V_CEO and different SC-89 package	Preferred for high-current, low-voltage battery-powered mute switches where 15 V headroom is unnecessary	Choose when prioritizing sub-150 mV saturation at >500 mA and board layout accommodates SC-89

Compared with MMBT3904LT1G and DXTN07100B-7, the 15C01M-TL-E uniquely balances 15 V V_CEO, 700 mA I_C, and 150 mV V_CE(sat) in SC-70 - making it optimal for space-limited 12 V audio subsystems requiring both voltage margin and thermal efficiency.

FAQ

What is the maximum continuous collector current rating for the 15C01M-TL-E?

The 15C01M-TL-E has a maximum continuous collector current (I_C) rating of 700 mA at T_A = 25°C when mounted on a standard glass-epoxy board (20 × 30 × 1.6 mm). Derating applies above 25°C ambient, with full rating maintained up to 75°C per typical PC–T_A curves in the datasheet. Pulse current capability reaches 1.4 A for short durations.

Does the 15C01M-TL-E support Pb-free and halide-free manufacturing requirements?

Yes, the 15C01M-TL-E is explicitly certified Pb-free and halide-free per J-STD-609 Category 1 and RoHS Directive 2011/65/EU. The "-E" suffix in the part number denotes this compliance, and no performance or reliability trade-offs are associated with the lead-free termination finish.

What is the typical V_CE(sat) of the 15C01M-TL-E under standard switching conditions?

The 15C01M-TL-E exhibits a typical V_CE(sat) of 150 mV at I_C = 200 mA and I_B = 10 mA (IC/IB = 20), with a guaranteed maximum of 300 mV under those same conditions. This low saturation voltage is confirmed across temperature (−25°C to +75°C) and supports efficient operation in battery-sensitive audio mute applications.

Which package type does the 15C01M-TL-E use, and what are its key mechanical dimensions?

The 15C01M-TL-E uses the SC-70 package (also designated MCP3, Case 419AJ), with nominal dimensions of 2.0 mm × 1.25 mm × 0.9 mm (length × width × height). It features gull-wing leads, a 0.65 mm lead pitch, and is optimized for reflow soldering per J-STD-020 moisture sensitivity level 1.

Can the 15C01M-TL-E be used in linear amplifier configurations?

Yes, the 15C01M-TL-E is characterized for linear operation with h_FE = 300–800 at V_CE = 2 V and I_C = 10 mA, and its f_T = 330 MHz supports stable gain up to mid-audio frequencies. Application notes confirm use in common-emitter preamplifier stages where low noise and predictable DC bias are required - though it is not optimized for RF or high-fidelity audio linearity.
