Product details
Overview
DCP68-25-13 from Diodes Incorporated is a 20V NPN medium-power transistor in SOT223 package, rated for 1.0A continuous collector current, 1W power dissipation, and 330MHz transition frequency, with DC current gain (hFE) of 160–375 at VCE = 1.0V and IC = 500mA, used in medium-power switching and amplification circuits such as DC-DC converter output stages and motor driver pre-drivers.
For engineers reviewing the DCP68-25-13 datasheet, DCP68-25-13 pinout, DCP68-25-13 application, or DCP68-25-13 equivalent, key selection considerations include its SOT223 thermal performance (RθJA = 125°C/W), VCEO = 20V rating, BVEBO = 5.0V emitter-base breakdown, and suitability for automotive-grade assembly processes requiring lead-free, halogen-free, and AEC-Q101-capable alternatives.
Technical Context
This NPN bipolar junction transistor employs epitaxial planar die construction for stable gain and low leakage, optimized for linear amplification and saturated switching in medium-power applications where thermal management on FR4 PCBs is constrained. Its 125°C/W junction-to-ambient thermal resistance assumes minimum recommended 1oz copper pad layout under still-air conditions.
The device delivers hFE = 160–375 at IC = 500mA and VCE = 1.0V, with VCE(sat) ≤ 0.5V at IC = 1.0A/IB = 100mA, and fT = 330MHz at IC = 100mA/VCE = 5.0V, supporting high-speed switching up to several tens of MHz in Class-A/AB amplifier stages and PWM-driven loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum allowable collector-emitter voltage before breakdown under open-base condition; defines safe operating voltage headroom in switching applications. |
| IC (continuous) | 1.0 A - Continuous DC collector current rating; sets maximum load drive capability without derating at TA = 25°C. |
| PD | 1 W - Maximum steady-state power dissipation on standard FR4 PCB; determines thermal design margin for heatsinking or airflow requirements. |
| hFE | 160–375 - DC current gain range at VCE = 1.0V, IC = 500mA; impacts base drive sizing and stability in linear or saturated operation. |
| fT | 330 MHz - Transition frequency at IC = 100mA, VCE = 5.0V; indicates usable bandwidth for RF amplification or fast-switching control loops. |
| RθJA | 125 °C/W - Junction-to-ambient thermal resistance; defines temperature rise per watt dissipated on minimal copper pad layout. |
Pinout & Package
Package: SOT223 - surface-mount plastic package with exposed thermal pad (collector-connected), rated for 125°C/W RθJA, UL 94V-0 flammability, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | E | Current return path; connected to ground or low-side reference; must handle full load current in common-emitter configurations. |
| Pin 2 (Base) | B | Control input; requires ~100mA drive for full saturation at 1A collector current; sensitive to ESD due to 5.0V VEBO limit. |
| Pin 3 (Collector) | C | High-side output node; electrically tied to thermal tab; must be routed over internal copper pour for thermal relief in power applications. |
| Pin 4 (Collector / Thermal Tab) | C (common with Pin 3) | Primary heat conduction path; soldered directly to PCB copper area; not electrically isolated from collector terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Ensures consistent hFE distribution and low leakage (ICBO ≤ 100nA), critical for stable biasing in analog amplifiers and precision switches. |
| SOT223 thermal pad (collector-connected) | Enables direct PCB copper thermal coupling, achieving 125°C/W RθJA without external heatsink in space-constrained industrial modules. |
| Lead-free, halogen-free, RoHS 3 compliant | Meets automotive and industrial environmental mandates (Br+Cl < 1500ppm, Sb < 1000ppm); supports automated reflow without tin whisker risk. |
| Complementary PNP pairing (DCP69) | Allows matched push-pull output stage design with identical thermal and gain characteristics, reducing crossover distortion in Class-B amplifiers. |
Applications
| DC-DC Converter Output Stage | Brushed DC Motor Pre-Driver |
|---|---|

| Linear Voltage Regulator Pass Element | Audio Amplifier Output Stage |
|
Use Scenario: Series pass transistor in adjustable 3.3V/1A linear regulator for noise-sensitive analog subsystems. IC Role / Device Role / Timing Role: Linearly biased NPN transistor dissipating variable power based on input-output differential; thermally coupled to PCB copper. Use Value: 20V VCEO accommodates 24V input rails; 125°C/W RθJA allows 1W dissipation with ≤125°C junction rise on 1oz copper. |
Use Scenario: Single-ended Class-A output stage in low-power audio signal chain for industrial HMI displays. IC Role / Device Role / Timing Role: Medium-power NPN amplifier delivering 0.5W into 8Ω load; biased at 500mA quiescent current for low crossover distortion. Use Value: hFE = 160–375 ensures predictable bias stability across temperature; fT = 330MHz preserves audio band fidelity up to 20kHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZTX653 | VCEO = 60V, IC = 1.5A, hFE = 100–800, SOT89 package, RθJA = 150°C/W | Higher voltage rating but worse thermal resistance; lacks automotive qualification and green material compliance | Select when >20V rail tolerance is required and board-level thermal design permits higher RθJA. |
| MJD122G | VCEO = 100V, IC = 8A, hFE = 20–100, TO-252 package, RθJA = 62.5°C/W | Higher current/power capability but lower hFE and larger footprint; not RoHS 3 or halogen-free certified | Choose for high-current (>2A) switching where gain linearity is secondary and thermal mass is available. |
Compared with ZTX653 and MJD122G, DCP68-25-13 offers superior thermal efficiency per unit area (125°C/W in SOT223), guaranteed halogen-free compliance, and tighter hFE consistency-making it optimal for space-constrained, environmentally regulated industrial and automotive-adjacent designs where 20V/1A operation suffices.

FAQ
Is DCP68-25-13 still in active production?
No-DCP68-25-13 is marked "Obsolete" in Diodes' official ordering information (DS30797 Rev. 7-2). However, Aetrix Electronics maintains legacy inventory with full traceability and provides last-time-buy support, including extended warranty and documentation packages for ongoing production continuity.
What is the marking code for DCP68-25-13 on the device body?
The top-side marking is "N12-25", where "N12" identifies the DCP68 base type and "-25" denotes the -25 variant. This is followed by a date code (e.g., "123" = year 2021, week 23), per Diodes' SOT223 marking specification in DS30797.
Can DCP68-25-13 replace DCP68-13 in existing designs?
Yes-both share identical electrical specifications, package, and pinout. The "-25" suffix reflects a specific tape-and-reel configuration (13-inch reel, 12mm tape width, 2500 units/reel) and minor process revision; no functional or parametric differences exist between DCP68-13 and DCP68-25-13.
Does DCP68-25-13 meet AEC-Q101 requirements for automotive use?
DCP68-25-13 itself is not AEC-Q101 qualified per Diodes' documentation, but the DCP68 family is offered in AEC-Q101 variants (e.g., DCP68Q) manufactured in IATF 16949-certified facilities. For automotive applications, engineers should specify the Q-grade version and engage Diodes' automotive team for PPAP support.
