Product details
Overview
DCP69A-13 from Diodes Incorporated is a PNP epitaxial planar silicon transistor in SOT-223 package, rated for -20 V VCEO, -1.0 A IC, and 1 W power dissipation at 25°C ambient. It delivers hFE = 100–250 at IC = -500 mA, VCE = -1.0 V, with VCE(SAT) ≤ -0.5 V at IC = -1.0 A / IB = -100 mA, and is used in medium-power switching circuits such as DC-DC converter bias stages and relay drivers.
For engineers reviewing the DCP69A-13 datasheet, DCP69A-13 pinout, DCP69A-13 application, or DCP69A-13 equivalent, key selection factors include its SOT-223 thermal performance (RθJA = 125°C/W), complementary NPN pairing with DCP68, RoHS-compliant matte tin plating, and suitability for automated SMT assembly in industrial power control modules.
Technical Context
This PNP bipolar junction transistor employs epitaxial planar die construction for stable gain and low leakage. Its breakdown ratings-V(BR)CEO = -20 V, V(BR)CBO = -25 V, and V(BR)EBO = -5.0 V-define safe operating limits under reverse-biased conditions, while fT = 250 MHz supports moderate-frequency amplification up to ~100 MHz.
Operation is characterized by pulsed testing (300 μs width, <2% duty cycle) per JEDEC standards. The device exhibits VBE(ON) = -1.0 V at IC = -1.0 A and shows typical hFE roll-off above 500 mA, confirming design intent for medium-current switching rather than linear amplification at full rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20 V - Maximum collector-emitter voltage before avalanche conduction in common-emitter configuration |
| IC | -1.0 A - Continuous DC collector current rating at 25°C ambient, derated above 25°C per Fig. 1 |
| PD | 1 W - Total power dissipation on FR-4 PCB with Diodes Inc. recommended pad layout (AP02001) |
| hFE | 100–250 - DC current gain range at IC = -500 mA, VCE = -1.0 V, defining base drive sizing margin |
| VCE(SAT) | ≤ -0.5 V - Saturation voltage at IC = -1.0 A / IB = -100 mA, limiting conduction loss in switch mode |
| fT | 250 MHz - Current gain-bandwidth product at IC = -100 mA, VCE = -5.0 V, f = 100 MHz |
| RθJA | 125 °C/W - Thermal resistance from junction to ambient air, measured on standard FR-4 board |
Pinout & Package
Package: SOT-223, surface-mount plastic case with exposed collector tab (pin 2 and 4 electrically connected), UL 94V-0 rated molding compound, moisture sensitivity level 1 per J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current exit path in PNP operation; tied to higher potential rail in high-side switch configurations |
| 2 (Collector) | C | Main current sink terminal; electrically connected to pin 4 for enhanced thermal conduction via PCB copper pour |
| 3 (Base) | B | Control input requiring negative current relative to emitter to forward-bias BE junction |
| 4 (Collector Tab) | C | Thermal and electrical extension of collector; must be soldered to large copper area for 1 W operation |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Ensures consistent hFE distribution and low leakage (ICBO ≤ -100 nA, IEBO ≤ -10 μA) across production lots |
| SOT-223 package with exposed collector tab | Enables 1 W dissipation on standard FR-4 via pins 2+4 thermal connection to PCB copper |
| Lead-free / RoHS-compliant plating | Matte tin annealed over copper leadframe meets MIL-STD-202 solderability requirements |
| Complementary NPN pairing (DCP68) | Supports push-pull or H-bridge designs without cross-manufacturer qualification effort |
Applications
| DC-DC Converter Bias Stage | Industrial Relay Driver |
|---|---|
Use Scenario: Providing base current to main switching transistor in isolated flyback or forward converter feedback circuits. IC Role / Device Role / Timing Role: Medium-current PNP switch enabling precise turn-on/turn-off timing of primary-side MOSFET gate drivers. Use Value: VCE(SAT) ≤ -0.5 V minimizes power loss in bias path; hFE ≥ 100 ensures stable drive with low base current overhead. | Use Scenario: Driving 24 VDC industrial relays requiring 20–50 mA coil current in PLC output modules. IC Role / Device Role / Timing Role: High-gain PNP interface between microcontroller GPIO and relay coil, providing inverted logic-level switching. Use Value: -1.0 A IC rating accommodates relay inrush peaks; SOT-223 thermal mass prevents thermal runaway during repeated actuation. |
| LED String Current Sink | Linear Voltage Regulator Pass Element |
Use Scenario: Acting as constant-current sink for 3–5 white LED strings in signage or indicator panels. IC Role / Device Role / Timing Role: Linear current regulator controlled by op-amp feedback loop, dissipating excess voltage as heat. Use Value: 1 W PD allows up to ~350 mA continuous current at 2.8 V LED drop with 12 V supply; RθJA = 125°C/W enables passive cooling. | Use Scenario: Serving as pass transistor in low-noise 5 V or 3.3 V linear regulators for analog sensor front-ends. IC Role / Device Role / Timing Role: Adjustable series pass element with external resistor divider setting output voltage. Use Value: V(BR)CEO = -20 V supports input up to 18 V; VBE(ON) = -1.0 V simplifies base bias network design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DCP69-13 | Same SOT-223 package, identical pinout, but specified for -1.5 A IC and 1.5 W PD; hFE min = 100 at IC = -1.0 A | Higher current headroom supports longer relay coil surge durations and higher LED string counts | Select when >1.0 A peak load current or >1 W dissipation is required; otherwise DCP69A-13 suffices |
| MMBT4403-7-F | SOT-23 package, lower PD = 350 mW, IC = -600 mA, VCEO = -40 V; hFE = 50–250 | Limited to low-power signal switching; unsuitable for 1 W thermal loads due to package size | Choose only for space-constrained signal-level inversion where thermal load < 300 mW |
Compared with DCP69A-13, DCP69-13 offers higher current and power capability in identical footprint, while MMBT4403-7-F trades thermal capacity for board area savings-making DCP69A-13 the optimal balance of SOT-223 manufacturability, 1 W thermal handling, and proven reliability in industrial control interfaces.

FAQ
Is DCP69A-13 pin-compatible with DCP69-13?
Yes, DCP69A-13 and DCP69-13 share identical SOT-223 pinout (Emitter-Base-Collector-Collector tab), mechanical dimensions, and marking layout. Both devices use the same PCB footprint and reflow profile, enabling direct substitution in layouts designed for either part without redesign.
What is the maximum allowable junction temperature for DCP69A-13?
The DCP69A-13 has an absolute maximum junction temperature (Tj) of +150°C, as specified in its operating temperature range. Derating begins at 25°C ambient per Fig. 1: power dissipation must be reduced linearly to zero at +150°C case temperature, assuming RθJA = 125°C/W on standard FR-4.
Does DCP69A-13 support lead-free reflow soldering?
Yes, DCP69A-13 features matte tin annealed over copper leadframe and complies with JEDEC J-STD-020C moisture sensitivity level 1. It is qualified for standard Pb-free reflow profiles (peak 260°C, 10-second dwell) and meets MIL-STD-202 Method 208 solderability requirements.
Why is DCP69A-13 marked "Not Recommended for New Designs"?
Diodes Incorporated issued this notice because DCP69-13 offers improved specifications (higher IC, PD, and tighter hFE binning) in the same SOT-223 package. The DCP69A-13 remains fully manufactured and supported for legacy designs, but new projects should evaluate DCP69-13 for better margin and longevity.
