Product details
Overview
DCP52-13 from Diodes Incorporated is a PNP epitaxial planar silicon transistor in SOT-223 package, rated for -60 V VCEO, -1 A continuous collector current, and 1 W power dissipation at TA = 25°C, used in medium-power switching and linear amplification circuits such as DC-DC converter bias stages and relay drivers.
For engineers reviewing the DCP52-13 datasheet, DCP52-13 pinout, DCP52-13 application, or DCP52-13 equivalent, key selection criteria include its -60 V breakdown rating, hFE range of 40–250 at IC = -150 mA, VCE(SAT) ≤ -0.5 V at IC = -500 mA/IB = -50 mA, thermal resistance of 125 °C/W, and RoHS-compliant matte tin plating on copper leadframe.
Technical Context
This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with verified DC current gain (hFE) spanning 40 to 250 depending on collector current and voltage conditions. Its V(BR)CEO = -60 V and V(BR)CBO = -60 V confirm symmetrical high-voltage blocking capability across collector-base and collector-emitter junctions.
Thermal performance is defined for two mounting conditions: 125 °C/W RθJA on FR-4 PCB (Note 3), and lower thermal resistance on polyimide with 1.8 cm² copper area (Note 4). Transition frequency fT = 200 MHz at IC = -50 mA/VCE = -5 V supports medium-frequency small-signal amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60 V - maximum safe collector-emitter voltage before avalanche breakdown in common-emitter configuration |
| IC (continuous) | -1 A - maximum DC collector current sustainable with adequate heatsinking at 25°C ambient |
| PD | 1 W - power dissipation limit on standard FR-4 PCB per manufacturer's recommended pad layout |
| hFE | 40–250 - DC current gain range measured at IC = -150 mA, VCE = -2 V; enables predictable base drive sizing |
| VCE(SAT) | ≤ -0.5 V - low saturation voltage at IC = -500 mA/IB = -50 mA, minimizing conduction loss in switching use |
| fT | 200 MHz - transition frequency confirming usable bandwidth for audio and low-RF amplification |
| RθJA | 125 °C/W - junction-to-ambient thermal resistance defining temperature rise per watt on reference PCB |
Pinout & Package
Package: SOT-223 - surface-mount plastic package with exposed thermal pad (pin 4), rated UL 94V-0, moisture sensitivity level 1, and 0.115 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Collector) | Main current sink terminal | Connected to load return path; electrically tied to thermal pad (pin 4) for enhanced heat transfer |
| 2 (Base) | Control input | Receives forward-biased current to turn on transistor; requires current-limiting resistor in series |
| 3 (Emitter) | Current source terminal | Typically connected to positive rail in PNP switching; defines reference for VBE and VCE |
| 4 (Collector/Thermal Pad) | Collector extension & thermal interface | Internally bonded to pin 1; must be soldered to large copper pour for thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Ensures consistent hFE distribution and stable breakdown characteristics across production lots |
| SOT-223 package with integrated thermal pad | Enables 1 W power handling without external heatsink when mounted per AP02001 pad layout |
| Lead-free / RoHS-compliant plating | Matte tin annealed over copper leadframe meets JEDEC J-STD-020C solderability and environmental compliance |
| Complementary NPN type available (DCP55) | Facilitates matched-pair design in push-pull output stages or differential amplifiers |
Applications
| DC-DC Converter Bias Control | Industrial Relay Driver |
|---|---|
Use Scenario: Provides base drive for PNP pass transistors in adjustable linear regulators or feedback error amplifiers within isolated DC-DC modules. IC Role / Device Role / Timing Role: Medium-current PNP switch regulating reference voltage or enabling/disabling secondary-side control circuitry. Use Value: -60 V VCEO withstands transient spikes on 24 V/48 V bus rails; VCE(SAT) ≤ -0.5 V limits power loss during regulation. | Use Scenario: Drives coil of 24 VDC industrial relays requiring ~50–100 mA hold current and higher inrush current. IC Role / Device Role / Timing Role: High-gain PNP switch interfacing microcontroller GPIO (active-low) to relay coil with flyback diode protection. Use Value: hFE ≥ 40 at IC = -100 mA ensures reliable saturation with ≤2 mA base drive; SOT-223 thermal pad sustains repeated switching cycles. |
| Audio Pre-amplifier Stage | Overvoltage Protection Clamp |
Use Scenario: Used in discrete Class-A preamp stages for sensor signal conditioning where low-noise, linearity, and supply headroom matter. IC Role / Device Role / Timing Role: Common-emitter amplifier biased in active region for small-signal voltage gain with minimal distortion. Use Value: fT = 200 MHz provides ample bandwidth beyond audio band; V(BR)EBO = -5 V allows safe operation with ±5 V bias networks. | Use Scenario: Configured in emitter-follower or shunt mode to clamp transient overvoltages on 12–24 V power rails in automotive body electronics. IC Role / Device Role / Timing Role: Fast-turn-on PNP clamp activated by Zener-referenced base bias during overvoltage events. Use Value: V(BR)CEO = -60 V sets precise clamping threshold; ICM = -1.5 A peak handles short-duration surges without second breakdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP52 | Same SOT-223 package, identical VCEO/IC/hFE specs, but obsolete per Diodes Inc. documentation | No functional difference; BCP52 was predecessor to DCP52 series with same pinout and electrical behavior | Select DCP52-13 for new designs due to active status and documented RoHS compliance |
| BCP52-16 | Identical die and package, differing only in date code and reel packaging; marked "Not Recommended for New Design" in DS30708 Rev. 7 | Same electrical and thermal performance; not suitable for long-term design-in due to obsolescence notice | Prefer DCP52-13 for volume procurement and lifecycle assurance |
Compared with BCP52 and BCP52-16, DCP52-13 offers identical PNP transistor functionality but with formal product status, updated RoHS documentation, and guaranteed supply continuity-critical for industrial OEMs managing multi-year production programs.

FAQ
Is DCP52-13 pin-compatible with BCP52?
Yes, DCP52-13 is mechanically and electrically pin-compatible with BCP52: both use SOT-223 package with identical pin 1–3 assignments (Collector–Base–Emitter) and shared thermal pad (pin 4). The datasheets confirm matching maximum ratings, hFE, and VCE(SAT) values under identical test conditions.
What is the maximum allowable junction temperature for DCP52-13?
The absolute maximum junction temperature (Tj) for DCP52-13 is +150°C, as specified in the Thermal Characteristics table. Operation above this temperature risks permanent degradation of the epitaxial planar die structure and accelerated parameter drift, even if ambient temperature remains within -55°C to +150°C storage limits.
Can DCP52-13 be used in linear regulator pass elements?
DCP52-13 can serve as a medium-power PNP pass transistor in linear regulators up to ~1 W dissipation, provided thermal design maintains Tj ≤ 150°C. Its VCEO = -60 V and VCE(SAT) ≤ -0.5 V support 24 V input–5 V output configurations, but SOA limitations require careful attention to simultaneous VCE and IC during dropout conditions.
Does DCP52-13 require derating above 25°C ambient?
Yes, DCP52-13 requires linear power derating above 25°C ambient: Fig. 1 shows PD decreases from 1 W at 25°C to zero at ~125°C on FR-4 PCB. Derating slope is -8 mW/°C (1 W ÷ 125 °C), meaning at 75°C ambient, max allowable dissipation drops to 0.6 W to maintain Tj ≤ 150°C.
