Product details
Overview
DCX69-13 from Diodes Incorporated is a PNP bipolar junction transistor in SOT89 package, rated for -20 V VCEO, -1.0 A IC, and 1 W power dissipation at 25°C ambient. It delivers hFE = 50–375 (depending on bias), VCE(SAT) ≤ -0.5 V at -1.0 A/-100 mA, and fT = 40–200 MHz - optimized for medium-power switching and linear amplification in automotive and industrial control circuits.
For engineers reviewing the DCX69-13 datasheet, DCX69-13 pinout, DCX69-13 application, or DCX69-13 equivalent, key selection criteria include its AEC-Q101 qualification, SOT89 thermal performance (RθJA = 125°C/W), -55°C to +150°C operating range, and discrete PNP switching behavior with verified saturation voltage and gain linearity across temperature.
Technical Context
This PNP transistor uses epitaxial planar die construction and is designed for stable DC and pulsed operation in medium-power analog and switching roles. Its VCEO = -20 V and IC = -1.0 A rating support robust current sinking in load-switching configurations, while fT ≥ 40 MHz enables use in low-frequency signal amplification up to ~100 MHz under specified bias.
The device operates across -55°C to +150°C with guaranteed hFE variation (e.g., DCX69-16: 100–250 at -500 mA), and exhibits VBE(ON) ≤ -1.0 V and VCE(SAT) ≤ -0.5 V under high-current drive - critical for minimizing conduction loss in relay drivers and power supply enable stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20 V - Maximum collector-emitter blocking voltage before breakdown; defines safe operating voltage in high-side switch or amplifier output stage. |
| IC | -1.0 A - Continuous collector current rating; supports medium-power load switching (e.g., solenoids, LED arrays) without forced cooling. |
| PD | 1 W @ 25°C - Power dissipation limit on FR-4 PCB; requires thermal pad layout per AP02001 for reliable derating above 25°C ambient. |
| hFE | 50–375 - DC current gain range across models and bias points; enables predictable base drive sizing for saturated switching or linear gain staging. |
| fT | 40–200 MHz - Current gain-bandwidth product; confirms suitability for audio-frequency amplification and fast digital switching (ton/toff < 100 ns). |
| RθJA | 125°C/W - Junction-to-ambient thermal resistance; determines temperature rise under load and informs heatsink/no-heatsink design decisions. |
Pinout & Package
Package: SOT89 - surface-mount, 3-pin plastic molded case with exposed thermal tab (pin 2/4 tied to collector); UL 94V-0 rated, moisture sensitivity level 1, weight ≈ 0.055 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current exit path in PNP operation; connected to higher-potential rail in high-side switch configuration. |
| 2 & 4 (Collector) | C | Dual-collector terminals bonded internally; used jointly for thermal and current handling - must be soldered to large copper pour. |
| 3 (Base) | B | Control input for forward-biased PNP operation; requires negative base current relative to emitter to turn on. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability - supports deployment in engine control, body electronics, and ADAS subsystems without additional qualification. |
| SOT89 thermal pad | Exposed collector tab enables direct thermal coupling to PCB copper; achieves 1 W dissipation with minimal external heatsinking. |
| Green RoHS compliance | No intentionally added lead, halogen-free (<900 ppm Br/Cl), antimony-free - meets EU Directive 2011/65/EU and automotive environmental requirements. |
| Low VCE(SAT) | ≤ -0.5 V at -1.0 A/-100 mA - reduces conduction loss by >30% vs. standard PNP transistors, improving efficiency in battery-powered load switches. |
Applications
| Automotive Relay Driver | Industrial Power Supply Enable |
|---|---|
Use Scenario: Driving 12 V automotive relays (e.g., HVAC fan, headlight control) from microcontroller GPIO. IC Role / Device Role / Timing Role: PNP high-side switch sinking base current to activate relay coil. Use Value: VCEO = -20 V withstands load dump transients; AEC-Q101 rating ensures longevity in under-hood environments. |
Use Scenario: Enabling 24 V industrial SMPS outputs via remote ON/OFF control signal. IC Role / Device Role / Timing Role: Discrete PNP switch controlling enable pin of DC-DC controller IC. Use Value: Low VCE(SAT) minimizes voltage drop across switch; SOT89 thermal performance sustains continuous 500 mA enable current. |
| LED Array Current Sink | Linear Audio Pre-amplifier Stage |
Use Scenario: Constant-current sinking for multi-segment indicator LEDs in medical equipment panels. IC Role / Device Role / Timing Role: Linear-mode PNP current regulator with emitter resistor feedback. Use Value: Tight hFE tolerance (DCX69-25: 160–375) enables accurate current setting; -55°C to +150°C range supports sterilization cycles. |
Use Scenario: Low-noise pre-amplifier stage for analog sensor signals (e.g., thermocouple, strain gauge) in test equipment. IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier with DC bias network. Use Value: fT ≥ 40 MHz ensures flat gain response up to 20 kHz; low Cobo = 17 pF minimizes Miller effect distortion. |
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 |
|---|---|---|---|
| BCX69-25 | Same SOT89 package, identical VCEO/IC/hFE specs; direct replacement per Diodes' obsolescence notice. | Identical functional role; no circuit redesign required. | Preferred upgrade path - actively manufactured, same footprint and electrical behavior. |
| MJD2955T4G | TO-220 package, higher IC (-10 A), higher PD (15 W); larger size and different thermal interface. | Requires PCB layout change and heatsink integration; suited for higher-power loads (>2 A). | Use only when DCX69-13 thermal margin is insufficient; not drop-in due to package and pinout mismatch. |
Compared with BCX69-25 and MJD2955T4G, DCX69-13 offers legacy compatibility in SOT89 but lacks active production support; BCX69-25 matches all electrical and mechanical specs exactly, while MJD2955T4G trades compactness for higher power handling - requiring full thermal and layout revalidation.

FAQ
Is DCX69-13 still in active production?
No - DCX69-13 is officially obsolete per Diodes' DS31264 Rev. 7 (June 2021). Diodes recommends BCX69-25 as the direct replacement. Aetrix Electronics maintains limited legacy stock for repair and maintenance use, with full traceability and date-code verification.
What is the correct pinout orientation for DCX69-13 on PCB layout?
Top view: Pin 1 = Emitter, Pins 2 & 4 = Collector (internally shorted), Pin 3 = Base. The SOT89 outline shows pin 2 and 4 as separate leads but electrically tied to the same collector node - both must connect to the thermal pad/copper pour.
Can DCX69-13 replace BCX69-16 in an existing design?
Yes, with verification: both share SOT89 package and overlapping hFE ranges (DCX69-16: 100–250; DCX69: 50–375), but DCX69-13 has lower minimum hFE. Confirm base drive capability and saturation voltage under worst-case conditions before substitution.
Does DCX69-13 require a heatsink in 1 W operation?
Not necessarily - its RθJA = 125°C/W means ΔT = 125°C at 1 W on standard FR-4 with Diodes' AP02001 pad layout. At 25°C ambient, junction reaches 150°C (max rated), so operation at full 1 W requires careful thermal design or derating above 25°C ambient.
