Product details
Overview
2DB1424R-13 from Diodes Incorporated is a PNP bipolar junction transistor in SOT89-3L package, rated for -20 V VCEO, -3 A continuous collector current, and 1 W power dissipation at TA = 25°C. It delivers hFE of 180–390 at VCE = -2 V / IC = -0.1 A and VCE(SAT) ≤ -0.5 V at IC = -2 A / IB = -0.1 A, suited for medium-power switching in DC-DC converter output stages.
For engineers reviewing the 2DB1424R-13 datasheet, 2DB1424R-13 pinout, 2DB1424R-13 application, or 2DB1424R-13 equivalent, key selection criteria include verified PNP polarity, SOT89-3L thermal performance (RθJA = 125°C/W), guaranteed VCEO and IC ratings, and complementary NPN pairing with 2DD2150.
Technical Context
This PNP transistor uses epitaxial planar die construction for stable gain and low saturation voltage. Its SOT89-3L package integrates a large copper leadframe for enhanced thermal conduction, supporting 1 W dissipation under defined PCB layout conditions (FR-4, AP02001 pad pattern).
Electrical behavior is characterized under pulsed test conditions (300 µs, ≤2% duty cycle) to avoid self-heating effects. Key AC parameters-fT = 220 MHz and Cobo = 28 pF-are specified at VCB = -10 V and VCE = -2 V, confirming suitability for medium-frequency switching up to ~100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (continuous) | -3 A - Continuous DC collector current capability with derating above 25°C ambient |
| PD | 1 W - Power dissipation limit on FR-4 PCB with specified pad layout per AP02001 |
| hFE | 180–390 - DC current gain range at VCE = -2 V, IC = -0.1 A, enabling predictable base drive design |
| VCE(SAT) | ≤ -0.5 V - Confirmed saturation voltage at IC = -2 A / IB = -0.1 A, minimizing conduction loss |
| fT | 220 MHz - Transition frequency indicating usable bandwidth for switching or amplification up to ~100 MHz |
Pinout & Package
SOT89-3L surface-mount package with exposed collector tab for thermal and electrical connection; molded green compound (UL 94V-0), matte tin-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Primary current-carrying terminal; electrically and thermally connected to exposed tab |
| 2 | Emitter | Current return path; tied to ground or low-side reference in PNP switch configurations |
| 3 | Base | Control input; requires negative bias relative to emitter to turn on device |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Ensures consistent hFE distribution and low leakage across production lots |
| Complementary NPN pairing (2DD2150) | Enables matched push-pull or H-bridge designs without cross-manufacturer qualification |
| Lead-free / RoHS-compliant plating | Matte tin annealed over copper supports Pb-free reflow profiles (J-STD-020D Level 1) |
| Optimized for automated assembly | SOT89-3L footprint and marking (P33R YWW) support high-yield pick-and-place and AOI verification |
Applications
| DC-DC Converter Output Stage | Linear Regulator Pass Element |
|---|---|
Use Scenario: Used as the high-side PNP switch in non-synchronous buck converters delivering 1–3 A load current. IC Role / Device Role / Timing Role: Medium-power PNP switching transistor controlling energy transfer to output filter inductor. Use Value: Low VCE(SAT) reduces conduction loss; 125°C/W RθJA enables operation up to 85°C ambient with minimal heatsinking. | Use Scenario: Functions as the series pass element in adjustable positive linear regulators (e.g., LDO derivatives). IC Role / Device Role / Timing Role: Voltage-controlled current source regulating output by modulating base-emitter bias. Use Value: High hFE minimizes base drive current; -20 V VCEO supports input-to-output differentials up to 18 V. |
| Motor Driver Half-Bridge | LED Constant-Current Sink |
Use Scenario: Integrated into discrete half-bridge circuits driving 12 V brushed DC motors in industrial actuators. IC Role / Device Role / Timing Role: Upper-leg PNP switch complementing N-channel MOSFET or NPN lower switch. Use Value: Matched timing with 2DD2150 allows precise dead-time control; robust fT ensures fast turn-off during PWM transitions. | Use Scenario: Configured as emitter-follower constant-current sink for high-brightness LED strings (e.g., signage backlighting). IC Role / Device Role / Timing Role: Current-regulating transistor with feedback resistor on emitter leg. Use Value: Tight hFE tolerance (180–390) enables ±5% current accuracy without trimming; -6 V VEBO prevents base-emitter breakdown during transient surges. |
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 |
|---|---|---|---|
| FCX718 | VCEO = -60 V, IC = -1 A, hFE = 100–300, SOT89-3L | Higher voltage rating but lower current capability; reduced power handling (0.5 W) | Preferred where higher breakdown margin is required and load current ≤1 A |
| 2DD2150 | NPN complement; VCEO = +20 V, IC = +3 A, hFE = 180–390, same SOT89-3L package | Opposite polarity; not interchangeable without circuit redesign | Select when building complementary pairs or NPN-based topologies requiring matched gain/thermal profile |
Compared with FCX718 and 2DD2150, the 2DB1424R-13 uniquely balances -20 V / -3 A rating and 1 W dissipation in SOT89-3L-making it optimal for cost-sensitive, medium-current PNP switching where voltage headroom is constrained but thermal management must remain simple.

FAQ
Is 2DB1424R-13 still in active production?
No. The datasheet explicitly states "OBSOLETE – PART DISCONTINUED" and recommends FCX718 as a replacement. However, Aetrix Electronics maintains limited legacy inventory with full traceability and supports design continuity for existing production programs through controlled allocation and cross-reference guidance.
What is the thermal resistance of 2DB1424R-13 on standard FR-4 PCB?
RθJA is 125°C/W when mounted on FR-4 PCB using Diodes' recommended pad layout (AP02001). This value assumes no additional heatsinking and accounts for convection and conduction through the SOT89-3L exposed collector tab and copper traces.
Can 2DB1424R-13 be used in place of an NPN transistor like 2DD2150?
No. 2DB1424R-13 is a PNP device; 2DD2150 is its complementary NPN counterpart. Swapping them without inverting biasing and signal polarity will prevent proper circuit operation and may cause damage due to reverse-biased junctions or unintended conduction paths.
Does 2DB1424R-13 meet automotive AEC-Q101 requirements?
No. The datasheet does not list AEC-Q101 qualification. It is specified for industrial and commercial temperature ranges (-55°C to +150°C), but lacks stress-test documentation, failure-rate reporting, or part-family qualification required for automotive use.
