Product details
Overview
DCP55-16-13 from Diodes Incorporated is an NPN surface-mount bipolar junction transistor in SOT-223 package, rated for 60 V VCEO, 1 A continuous collector current, and 1 W power dissipation at TA = 25°C, with hFE of 40–250 at IC = 150 mA and VCE = 2 V. It serves as a medium-power switching or linear amplification device in DC-DC converters, relay drivers, and LED load controls.
For engineers reviewing the DCP55-16-13 datasheet, DCP55-16-13 pinout, DCP55-16-13 application, or DCP55-16-13 equivalent, key selection criteria include VCEO/VCBO voltage rating, hFE range at defined bias points, thermal resistance (RθJA = 125°C/W), saturation voltage (VCE(SAT) ≤ 0.5 V @ IC = 500 mA, IB = 50 mA), and SOT-223 thermal pad layout compatibility.
Technical Context
This NPN BJT uses epitaxial planar die construction and operates in active, saturation, and cutoff regions depending on base drive. Its complementary PNP counterpart is DCP52, enabling push-pull configurations. The device supports pulsed operation up to 1.5 A peak with ≤2% duty cycle and 300 μs pulse width.
Thermal performance depends on PCB mounting: RθJA is 125°C/W on FR-4 per AP02001 layout, and 70°C/W on polyimide with 1.8 cm² copper area. VBE(ON) is specified at 1.0 V under IC = 500 mA and VCE = 2 V, confirming low-turn-on threshold for efficient base drive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (continuous) | 1 A - Continuous DC collector current limit at TA = 25°C with derating above 25°C |
| hFE | 40–250 - DC current gain range at IC = 150 mA, VCE = 2 V; impacts base drive sizing |
| VCE(SAT) | ≤0.5 V @ IC = 500 mA, IB = 50 mA - Low saturation voltage minimizes conduction loss in switching use |
| fT | 200 MHz - Transition frequency defines usable bandwidth for small-signal amplification |
| RθJA | 125°C/W - Junction-to-ambient thermal resistance on standard FR-4 layout; dictates heatsinking needs |
| PD | 1 W @ TA = 25°C - Maximum power dissipation before thermal shutdown or degradation |
Pinout & Package
Package: SOT-223 - Surface-mount plastic package with integrated heat-dissipating tab (pin 3), rated for 1 W dissipation when mounted per AP02001 layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current exit path; connected to ground or low-side reference in switch applications |
| 2 (Base) | B | Control terminal; requires current-limited drive to achieve target IC and avoid overdrive |
| 3 (Collector) | C | Main current input; tied to load supply rail in low-side switch topology |
| 4 (Collector) | C | Second collector connection; electrically tied to pin 3 and used for thermal conduction to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Enables stable hFE across temperature and consistent VCE(SAT) performance |
| SOT-223 thermal pad (pin 3/4) | Provides direct thermal path to PCB copper, supporting 1 W operation without external heatsink |
| Lead-free/RoHS-compliant plating | Matte tin annealed over copper leadframe ensures solderability per MIL-STD-202, Method 208 |
| Moisture sensitivity Level 1 | No bake required prior to reflow; compatible with standard automated assembly processes |
| Complementary PNP (DCP52) | Enables matched pair design for Class-B amplifiers or H-bridge driver stages |
Applications
| DC-DC Converter Switching | Relay Driver Stage |
|---|---|
Use Scenario: Used as main power switch in non-synchronous buck converter operating at ≤100 kHz. IC Role / Device Role / Timing Role: NPN BJT configured in low-side switch topology, driven by PWM controller output. Use Value: VCEO = 60 V accommodates 48 V input rails; VCE(SAT) ≤ 0.5 V limits conduction loss at 500 mA load. | Use Scenario: Drives 12 V, 500 mA coil of industrial electromechanical relay. IC Role / Device Role / Timing Role: Medium-power interface transistor translating microcontroller GPIO to relay coil current. Use Value: hFE ≥ 40 ensures sufficient gain to saturate with 10–20 mA base drive; SOT-223 handles coil energy dissipation. |
| LED Constant-Current Driver | Linear Voltage Regulator Pass Element |
Use Scenario: Serves as adjustable current sink for high-brightness LED string in signage lighting. IC Role / Device Role / Timing Role: Active current-regulating element controlled by op-amp feedback loop. Use Value: fT = 200 MHz supports stable closed-loop response; VCEO = 60 V allows headroom for 24 V bus + LED forward drop. | Use Scenario: Functions as series pass transistor in 5 V, 1 A linear regulator with 12 V input. IC Role / Device Role / Timing Role: Dissipative voltage-drop element maintaining regulated output under load variation. Use Value: PD = 1 W and RθJA = 125°C/W permit ~7 V dropout at 1 A with <100°C junction rise on FR-4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP55 | Same VCEO/VCBO (60 V), but hFE min = 25 @ IC = 150 mA; identical SOT-223 package | Lower minimum gain may require increased base drive in margin-critical designs | Preferred where cost sensitivity outweighs hFE consistency requirements |
| BCP5516 | Identical electrical specs and marking code; direct functional replacement per Diodes Inc. documentation | No functional difference; same pinout, thermal behavior, and reliability profile | Recommended for new designs replacing DCP55-16-13 due to active status and full support |
Compared with DCP55-16-13, BCP55 offers lower guaranteed hFE and reduced design margin for base drive, while BCP5516 provides identical performance with ongoing manufacturing support-making it the preferred drop-in upgrade path.

FAQ
Is DCP55-16-13 RoHS compliant and lead-free?
Yes. DCP55-16-13 uses matte tin annealed over copper leadframe with no purposefully added lead, meeting RoHS Directive 2011/65/EU. It is classified as "Green" per Diodes Incorporated's environmental policy and passes solderability testing per MIL-STD-202, Method 208.
What is the maximum allowable junction temperature for reliable operation?
The absolute maximum junction temperature is +150°C, with storage temperature matching this range. Operation above 125°C requires derating of power dissipation per the thermal curve in DS30707 Rev. 7–3, and sustained operation near 150°C necessitates verified PCB thermal design per AP02001 layout.
Can DCP55-16-13 be used in linear amplifier configurations?
Yes. With fT = 200 MHz and hFE stability across IC, it supports small-signal amplification up to mid-VHF frequencies. Designers must ensure VCE remains within 60 V, limit power dissipation using RθJA = 125°C/W, and bias in the active region using appropriate base resistors.
Why is DCP55-16-13 marked "Not Recommended for New Design"?
Diodes Incorporated designated DCP55-16-13 as NRND because the newer BCP5516 offers identical specifications with enhanced process control, extended lifecycle support, and full qualification for automotive and industrial applications-while maintaining pin-for-pin and electrical compatibility.
