Product details
Overview
15C02CH-TL-E from onsemi is a low-VCE(sat) NPN bipolar transistor in CPH3 (SC-59/TO-236/SOT-23) package, rated for 15 V VCEO, 1 A IC, and 280 mV max VCE(sat) at IC=400 mA/IB=20 mA. It delivers high DC current gain (hFE = 300–800), 400 MHz fT, and ultra-low ON-resistance for compact motor drive and switching applications.
For engineers reviewing the 15C02CH-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified VCE(sat) performance at 400 mA, hFE consistency across temperature, CPH3 thermal dissipation on ceramic board (700 mW), and Pb-free TL reel packaging compliance.
Technical Context
This NPN transistor operates as a single-element, medium-current switching and amplification device with fixed emitter-base and collector-base junction structures. Its design emphasizes fast switching (ton = 30 ns, tf = 25 ns) and low saturation loss-enabled by optimized doping and geometry to achieve RCE(sat) ≈ 300 mΩ at IC = 1 A/IB = 50 mA.
The device is characterized under standard test conditions: VCE = 2 V for hFE and fT, VCB = 10 V for Cob, and pulsed operation for ICP = 2 A. Junction temperature is rated to 150°C, with storage range from –55°C to +150°C, supporting industrial ambient operation.
Key Specifications

|---|---|
| VCEO | 15 V - Maximum safe collector-emitter voltage before breakdown under open-base condition |
| IC | 1 A - Continuous DC collector current rating at Ta = 25°C on ceramic board |
| VCE(sat) max | 280 mV - Ensures minimal power loss and heat generation when fully saturated at 400 mA load |
| hFE | 300–800 - Provides stable current amplification for base-driven switching control circuits |
| fT | 400 MHz - Supports reliable operation in low-frequency amplifier and high-speed digital switching up to ~100 MHz |
| Cob | 4 pF - Limits high-frequency Miller capacitance, aiding fast turn-off and reducing switching distortion |
| PC | 700 mW - Thermal limit on 600 mm² × 0.8 mm ceramic board; defines PCB copper area requirement |

| 2 | Emitter | Common reference terminal; internally connected to PCB ground plane in low-side switch configurations |
| 3 | Collector | High-current output node; connects to load (e.g., motor coil or relay) with minimal VCE(sat) drop |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 280 mV max at IC = 400 mA enables >95% efficiency in 5 V motor drive stages |

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 | Lower IC (200 mA), higher VCE(sat) (300 mV min), same SOT-23 package | Not suitable for 400 mA+ loads; limited to signal-level switching | Select only for low-current biasing or logic interfacing where 15C02CH-TL-E's 1 A capability is unnecessary |
| BC817-40,215 | Higher VCEO (45 V), lower fT (100 MHz), same CPH3-compatible SOT-23 package | Better for higher-voltage industrial controls but slower for high-frequency PWM | Prefer when system voltage exceeds 15 V; avoid if >100 kHz switching or tight VCE(sat) tolerance is required |
Compared with MMBT3904LT1G and BC817-40,215, the 15C02CH-TL-E uniquely balances 1 A current handling, sub-300 mV saturation voltage, and 400 MHz bandwidth-making it optimal for compact, high-efficiency 5–12 V motor and power-switching designs where thermal and space constraints are critical.

FAQ
What is the maximum continuous collector current rating for the 15C02CH-TL-E?
The 15C02CH-TL-E is rated for 1 A continuous collector current (IC) at Ta = 25°C when mounted on a specified ceramic board (600 mm² × 0.8 mm). Derating applies above 25°C ambient, with thermal resistance defined by the PCB layout. This rating ensures reliable operation in sustained motor drive and power switching roles without exceeding the 150°C junction temperature limit.
Does the 15C02CH-TL-E support high-speed switching applications?
Yes, the 15C02CH-TL-E supports high-speed switching with documented ton = 30 ns and tf = 25 ns under standard test conditions. Its 400 MHz fT and low 4 pF output capacitance enable clean edges and minimal delay in PWM-based motor control and digital signal inversion up to several megahertz, provided layout minimizes parasitic inductance.
What is the VCE(sat) performance of the 15C02CH-TL-E at typical operating conditions?
The 15C02CH-TL-E achieves a maximum VCE(sat) of 280 mV at IC = 400 mA and IB = 20 mA, with typical value of 140 mV. This low saturation voltage directly reduces conduction losses and self-heating-critical for efficiency in battery-powered and thermally isolated applications where the 15C02CH-TL-E is commonly deployed.
Is the 15C02CH-TL-E RoHS-compliant and halogen-free?
Yes, the 15C02CH-TL-E is Pb-free and RoHS-compliant, as confirmed by its "-E" suffix and "Pb Free" marking in the ordering information. The device meets JESD204 and JEDEC standards for green packaging, with no brominated flame retardants or chlorine-based compounds in the mold compound or leadframe plating.
What package type does the 15C02CH-TL-E use, and is it compatible with standard SOT-23 footprints?
The 15C02CH-TL-E uses the CPH3 package, which is mechanically and dimensionally identical to JEITA SC-59, JEDEC TO-236, and industry-standard SOT-23. Its 2.9 mm × 1.6 mm outline, 0.95 mm height, and 1.4 mm lead pitch ensure full compatibility with automated SMT assembly lines and existing SOT-23 land patterns-no PCB redesign needed.
