Product details

Overview

15C01C-TB-E from onsemi is a low-V_CE(sat) NPN bipolar transistor in CP (SOT-23) package, rated for 15 V V_CEO, 700 mA I_C, and 300 mW P_C on glass epoxy board. It delivers typ. V_CE(sat) = 150 mV at I_C = 200 mA / I_B = 10 mA and h_FE = 300–800 at V_CE = 2 V / I_C = 10 mA, serving as a compact switching element in low-frequency amplifier and muting circuits.

For engineers reviewing the 15C01C-TB-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified low saturation voltage, confirmed SOT-23 (CP) package mapping, validated 3-pin terminal assignment, and documented f_T = 330 MHz gain-bandwidth performance under standard bias conditions.

Technical Context

This NPN transistor operates with fixed-base drive in linear and saturated switching modes. Its design emphasizes low conduction loss via R_CE(sat) ≈ 0.58 Ω (typ.) at I_C = 0.7 A / I_B = 35 mA and supports fast switching with t_on = 30 ns, t_stg = 77 ns, and t_f = 40 ns under defined test circuit conditions.

Thermal operation is specified up to T_j = 150 °C, with derating applied per the P_C–T_a curve for mounting on 20×30×1.6 mm glass epoxy board. Electrical behavior is characterized across –25 °C to +75 °C ambient, with h_FE, V_CE(sat), and f_T all temperature-tracked in datasheet figures.

Key Specifications

f_T	330 MHz - Gain-bandwidth product at V_CE = 2 V / I_C = 50 mA, defining usable small-signal frequency limit
C_ob	3.2 pF - Output capacitance at V_CB = 10 V / f = 1 MHz, influencing high-frequency switching transitions
P_C	300 mW - Max power dissipation on standard 20×30×1.6 mm glass epoxy PCB, defining thermal layout constraints

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 @ I_C = 10 mA - higher voltage rating but lower current capacity	Preferred where overvoltage tolerance >20 V is required; unsuitable for 700 mA loads	Select when system-level transient protection demands higher V_CEO and load current remains ≤200 mA

FAQ

What is the maximum continuous collector current rating for the 15C01C-TB-E?

The 15C01C-TB-E has a maximum continuous collector current (I_C) rating of 700 mA at T_a = 25 °C, as specified in the Absolute Maximum Ratings table. This value assumes operation within Recommended Operating Conditions and proper PCB thermal management-specifically mounting on a 20×30×1.6 mm glass epoxy board. Exceeding this current may compromise reliability or trigger thermal shutdown in real-world layouts.

Does the 15C01C-TB-E support switching applications, and what are its key timing parameters?

Yes, the 15C01C-TB-E is qualified for switching use with documented t_on = 30 ns, t_stg = 77 ns, and t_f = 40 ns under the standard test circuit (V_CC = 5 V, R_L = 220 μF, I_C = 500 mA). These values confirm suitability for low-to-moderate frequency digital control, such as audio muting or LED enable/disable, where sub-100 ns transitions prevent signal distortion or power rail instability.

What package type does the 15C01C-TB-E use, and is it compatible with standard SOT-23 footprints?

The 15C01C-TB-E uses the CP package, which is JEDEC-registered as TO-236AB and functionally identical to SC-59 and SOT-23. Its mechanical dimensions (2.9 mm × 1.3 mm × 1.1 mm) and 3-pin terminal layout match industry-standard SOT-23 land patterns, enabling direct placement on existing SOT-23-referenced PCBs without footprint modification.

What is the typical DC current gain (h_FE) of the 15C01C-TB-E, and how does it vary with operating conditions?

The 15C01C-TB-E exhibits h_FE = 300–800 at V_CE = 2 V and I_C = 10 mA, with variation tracked across temperature in datasheet Figure 7. At I_C = 500 mA, h_FE drops to ~100–200 (per h_FE–I_C curve), confirming its optimized use in moderate-gain, medium-current switching rather than high-fidelity linear amplification.

Is the 15C01C-TB-E RoHS-compliant and halogen-free?

Yes, the 15C01C-TB-E is marked "Pb Free" in the Ordering Information section and conforms to RoHS Directive 2011/65/EU. The device uses lead-free matte tin plating on terminals and halogen-free molding compound, as verified by onsemi's material declarations and packaging specification EN7504A.
