Product details
Overview
2DB1386Q-13 from Diodes Incorporated is a PNP medium-power bipolar junction transistor in SOT89 package, rated for -20V VCEO, -5A continuous collector current, and VCE(sat) ≤ -0.25V at -4A/-0.1A drive-optimized for high-current switching in automotive body control modules, LED driver stages, and industrial power regulators.
For engineers reviewing the 2DB1386Q-13 datasheet, 2DB1386Q-13 pinout, 2DB1386Q-13 application, or 2DB1386Q-13 equivalent, key selection criteria include verified thermal resistance (RθJL = 19°C/W), AEC-Q101 readiness per manufacturer statement, complementary pairing with 2DD2098, and SOT89 lead-frame thermal performance under sustained 4A conduction.
Technical Context
This PNP transistor operates in linear or saturated switching mode with DC current gain (hFE) of 120–270 at -0.5A/-2V, supporting precise base-driven on/off control in low-side load configurations. Its -30V VCBO and -6V VEBO ratings ensure robustness against transient reverse bias in 12V/24V automotive systems.
Thermal design relies on the exposed collector pad: RθJL = 19°C/W enables efficient heat transfer to PCB copper, while RθJA = 125°C/W (on 15mm × 15mm × 0.6mm FR4) defines ambient-limited derating above 25°C-critical for under-hood applications up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (cont.) | -5 A - Continuous collector current capacity without thermal runaway on standard PCB layout |
| VCE(sat) | -0.25 V @ -4A/-0.1A - Low conduction loss enabling <1W dissipation in high-duty-cycle switching |
| hFE | 120–270 @ -0.5A/-2V - Stable DC gain range ensuring predictable base drive requirements |
| fT | 100 MHz - Sufficient bandwidth for PWM frequencies up to ~10 MHz with minimal phase lag |
| RθJL | 19 °C/W - Junction-to-lead thermal resistance confirming effective heat path via exposed collector pad |
| Cobo | 55 pF @ -20V - Output capacitance limiting high-frequency switching speed and EMI generation |
Pinout & Package
Package: SOT89 - Surface-mount plastic package with exposed collector pad for enhanced thermal dissipation; dimensions per Diodes outline SOT89 (D = 4.50 mm, E = 2.50 mm, H = 4.10 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter terminal | Current exit point in PNP operation; connected to higher potential rail in high-side switch configurations |
| Pin 2 (Base) | Control input | Receives negative base current to turn on; requires current-limiting resistor referenced to emitter |
| Pin 3 (Collector) | Power output node | Exposed metal pad functions as primary heat sink and main current path to load ground |
Key Features

| AEC-Q101 readiness | Qualified for automotive applications per manufacturer statement-supports PPAP and IATF 16949 manufacturing |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets global environmental compliance mandates |
| Complementary pairing | Matched with NPN 2DD2098 for push-pull or H-bridge designs requiring symmetrical switching characteristics |
Applications
| Automotive Body Control | Industrial Power Regulation |
|---|---|
|

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 |
|---|---|---|---|
| MJD127G | VCEO = -100V, IC = -2A, RθJA = 62.5°C/W (TO-252) | Higher voltage margin but lower current and inferior thermal performance than SOT89 | Select when >-20V blocking is required and board space allows TO-252 footprint |
| ZTX951 | VCEO = -60V, IC = -3A, hFE = 100–300 (SOT89) | Same package but lower current rating and higher VCE(sat) (~-0.5V @ -2A) | Use where reduced current demand permits trade-off in saturation loss and cost |
Compared with MJD127G and ZTX951, the 2DB1386Q-13 delivers superior thermal efficiency (RθJL = 19°C/W), higher continuous current (-5A), and lower conduction loss-making it optimal for compact, high-power-density automotive and industrial switching where SOT89 mounting is preferred.

FAQ
Is the 2DB1386Q-13 qualified to AEC-Q101?
Yes-the device is explicitly designated by Diodes Incorporated for automotive applications requiring AEC-Q101 qualification, PPAP capability, and manufacturing in IATF 16949 certified facilities. Full qualification documentation is available upon request through Diodes' automotive support channel.
What is the maximum allowable junction temperature for continuous operation?
The 2DB1386Q-13 has an operating junction temperature range of -55°C to +150°C. For continuous operation at full -5A current, thermal design must maintain TJ ≤ +150°C using the specified RθJL = 19°C/W path to the PCB copper, especially under elevated ambient conditions.
How does the SOT89 package affect thermal performance compared to TO-220 or DPAK?
The SOT89's exposed collector pad provides RθJL = 19°C/W-superior to typical DPAK (RθJL ≈ 30–40°C/W) and competitive with small TO-220 variants-while occupying less than 25% of the board area. This enables high-power density without sacrificing thermal reliability in space-constrained layouts.
Can the 2DB1386Q-13 be used in parallel for higher current handling?
No-BJT devices like the 2DB1386Q-13 exhibit positive temperature coefficient of VCE(sat), causing current hogging if paralleled without individual emitter resistors. Diodes does not recommend parallel operation; instead, select higher-rated alternatives or verify derated single-device operation per application thermal analysis.
