Product details

Overview

15C02MH-TL-E from onsemi is a low-V_CE(sat) NPN bipolar transistor in MCPH3 (SC-70/SOT-323) package, rated for 15 V V_CEO, 1 A I_C, and 300 mΩ typical R_CE(sat) at I_C = 1 A / I_B = 50 mA. It delivers high-speed switching and low-loss operation in compact motor drive and amplifier stages.

For engineers reviewing the 15C02MH-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat) ≤ 280 mV at 400 mA, f_T = 440 MHz gain-bandwidth, h_FE range of 300–800, and thermal performance on ceramic substrate (600 mm² × 0.8 mm).

Technical Context

This device operates as a single NPN switching transistor with optimized base drive efficiency: V_BE(sat) is 0.9–1.2 V at I_C = 400 mA / I_B = 20 mA, and switching times are t_on = 30 ns, t_stg = 165 ns, t_f = 25 ns under defined test conditions (V_CC = 5 V, R_L = 220 μF/470 μF, P_W = 20 μs).

Its small-signal behavior includes C_ob = 4 pF at V_CB = 10 V / f = 1 MHz and f_T = 440 MHz at V_CE = 2 V / I_C = 50 mA, supporting stable amplification up to UHF frequencies while maintaining low leakage (I_CBO ≤ 100 nA, I_EBO ≤ 100 nA).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	15 V - Maximum safe collector-emitter voltage before breakdown; defines rail limit in low-voltage switching circuits.
I_C	1 A continuous - Sustained current-handling capability for motor drivers and power switches without derating at 25°C.
V_CE(sat)	140–280 mV at I_C = 400 mA / I_B = 20 mA - Low conduction loss enabling >95% efficiency in 5 V logic-level driven loads.
f_T	440 MHz - Enables stable small-signal amplification up to UHF band; supports fast edge-rate digital switching.
h_FE	300–800 at V_CE = 2 V / I_C = 50 mA - Wide DC gain range allows flexible base resistor design across production lots.
C_ob	4 pF at V_CB = 10 V / 1 MHz - Minimal output capacitance reduces Miller effect and improves switching speed stability.
P_C	600 mW on ceramic substrate (600 mm² × 0.8 mm) - Thermal dissipation rating validated for surface-mount PCB layouts with defined copper area.

Pinout & Package

MCPH3 is a 3-pin ultrasmall plastic package (JEITA SC-70 / JEDEC SOT-323), measuring 2.1 mm × 1.6 mm × 0.85 mm, with 0.65 mm lead pitch and 7 mg mass. It enables high-density placement in space-constrained applications such as wearable motor controllers and portable audio amplifiers.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input requiring 20 mA drive for full saturation at 400 mA load; low V_BE(sat) minimizes base drive power.
2	Emitter	Common reference node tied to ground or low-side return path; low-impedance connection critical for stable saturation.
3	Collector	High-current output terminal; designed for direct connection to inductive loads (e.g., small DC motors) with minimal trace inductance.

Key Features

Feature	Design Value
Low V_CE(sat)	Typ. 140–280 mV ensures <115 mW conduction loss at 400 mA, reducing thermal stress in sealed enclosures.
Ultrasmall MCPH3 footprint	2.1 × 1.6 mm outline enables PCB real estate savings over SOT-23 in wearables and hearing aids.
High f_T	440 MHz bandwidth supports clean square-wave switching up to ~70 MHz clock edges without ringing.
Robust thermal rating	600 mW dissipation on standard ceramic substrate allows operation up to +75°C ambient without heatsinking.
Low leakage	I_CBO ≤ 100 nA at V_CB = 12 V ensures stable biasing in battery-powered sensor nodes over temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN switching transistor 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.	More suitable for general-purpose logic-level switching where load current ≤ 200 mA and rail voltage > 15 V.	Select when higher breakdown margin is required and load current is below 200 mA; not recommended for 1 A motor drive.
DXTN0101000000000	V_CEO = 12 V, I_C = 1 A, V_CE(sat) = 150 mV @ 500 mA - tighter V_CE(sat) spec but lower voltage rating and no published f_T.	Better for ultra-low-loss 12 V switching where RF performance is not required and thermal design prioritizes minimal V_CE(sat).	Prefer for cost-sensitive 12 V systems needing lowest possible conduction loss; verify layout compatibility with DFN1006 package.

Compared with MMBT3904LT1G and DXTN0101000000000, the 15C02MH-TL-E uniquely balances 15 V/1 A rating, sub-280 mV V_CE(sat), and 440 MHz f_T - making it optimal for compact 5–12 V motor and amplifier designs demanding both efficiency and bandwidth.

FAQ

What is the maximum continuous collector current for the 15C02MH-TL-E?

The 15C02MH-TL-E is rated for 1 A continuous collector current (I_C) at T_a = 25°C when mounted on a ceramic substrate (600 mm² × 0.8 mm). At elevated ambient temperatures, derating applies per the PC–Ta curve in the datasheet, with maximum junction temperature limited to 150°C. The 15C02MH-TL-E must not exceed this I_C rating under sustained DC or PWM conditions without thermal mitigation.

Is the 15C02MH-TL-E still in active production?

No - the 15C02MH-TL-E is officially discontinued per onsemi documentation (No.7354-1/6 through -6/6), marked "DISCONTINUED" with instruction to contact onsemi representatives for alternatives. Aetrix Electronics maintains legacy inventory and supports design continuity with verified equivalents and cross-reference guidance for the 15C02MH-TL-E.

What is the pin configuration of the 15C02MH-TL-E in the MCPH3 package?

The 15C02MH-TL-E uses a standardized 3-pin MCPH3 (SC-70/SOT-323) package with pin 1 = Base, pin 2 = Emitter, pin 3 = Collector - confirmed by onsemi's marking diagram and electrical connection table. This pinout is consistent across all MCPH3-packaged NPN transistors from onsemi and aligns with JEDEC SOT-323 mechanical standards. The 15C02MH-TL-E requires correct orientation during reflow to avoid functional failure.

Does the 15C02MH-TL-E support Pb-free soldering processes?

Yes - the 15C02MH-TL-E is explicitly labeled "Pb Free" in its ordering information and complies with RoHS Directive 2011/65/EU. It supports standard lead-free reflow profiles (J-STD-020D), including peak temperatures up to 260°C for 30 seconds. The 15C02MH-TL-E's plastic package and internal metallization are qualified for Pb-free assembly without delamination or wire bond integrity loss.

What is the typical gain-bandwidth product (f_T) of the 15C02MH-TL-E?

The 15C02MH-TL-E has a typical gain-bandwidth product (f_T) of 440 MHz, measured at V_CE = 2 V and I_C = 50 mA per onsemi's Electrical Characteristics table. This f_T value reflects its suitability for high-speed switching and narrowband amplification up to UHF frequencies. The 15C02MH-TL-E maintains usable gain beyond 100 MHz, enabling clean signal integrity in fast-edge digital interfaces.
