Product details
Overview
2DB1386R-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) ≤ -1.0V at -4A/-0.1A drive-designed for high-current switching in automotive body control modules, industrial power supplies, and LED driver stages.
For engineers reviewing the 2DB1386R-13 datasheet, 2DB1386R-13 pinout, 2DB1386R-13 application, or 2DB1386R-13 equivalent, key selection criteria include verified saturation voltage under high IC, thermal resistance to leads (19°C/W), hFE range of 180–390 at -0.5A, complementary NPN pairing with 2DD2098, and AEC-Q101 readiness per manufacturer qualification path.
Technical Context
This PNP transistor operates in linear or saturated switching mode with guaranteed breakdown margins: VCBO = -30V, VEBO = -6V, and safe operation up to +150°C junction temperature. Its low RθJL (19°C/W) enables efficient heat transfer from die to PCB copper via the exposed collector pad.
DC current gain is specified at 180–390 (min–max) at IC = -0.5A and VCE = -2V, with fT = 100MHz typical at VCE = -6V/ IE = 50mA-supporting moderate-speed switching in DC-DC feedback paths and load switch control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -20V - Maximum allowable collector-emitter voltage before avalanche conduction in common-emitter configuration. |
| IC (cont) | -5A - Continuous collector current rating defining maximum steady-state load switching capacity. |
| VCE(sat) | -0.25V to -1.0V @ -4A/-0.1A - Confirmed low on-state loss enabling <0.4W dissipation in saturated switch applications. |
| hFE | 180–390 @ -0.5A/-2V - Verified DC current gain range ensuring predictable base drive requirements across production lots. |
| RθJL | 19°C/W - Thermal resistance from junction to solder point, enabling direct thermal coupling to PCB copper for >1W power handling. |
| fT | 100MHz typical - Small-signal transition frequency confirming suitability for switching above 10MHz in feedback or gate-drive circuits. |
| Cobo | 55pF @ -20V - Output capacitance determining turn-off energy and Miller effect in high-speed switching nodes. |
Pinout & Package
Package: SOT89 - Surface-mount plastic package with exposed collector tab for thermal and electrical connection; dimensions per JEDEC MO-218AA (D2 = 1.71mm, E = 2.50mm, H = 4.10mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Current source terminal in PNP operation | Connected to higher potential rail; carries full load current when device is on. |
| Pin 2 (Base) | Control input for minority-carrier injection | Requires negative current relative to emitter to bias into active/saturation region. |
| Pin 3 (Collector) | Current sink terminal and thermal interface | Exposed metal pad electrically connected to collector; must be soldered to ≥15mm×15mm 1oz Cu for rated 1W dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| High current capability | -5A continuous collector current supports direct driving of solenoids, relays, and high-brightness LED strings without external buffers. |
| Low saturation voltage | VCE(sat) ≤ -1.0V at -4A ensures <4W conduction loss in 12V load-switch applications, reducing thermal stress. |
| Thermally optimized package | SOT89's exposed collector pad and RθJL = 19°C/W allow reliable 1W operation on standard FR4 with minimal heatsinking. |
| AEC-Q101 qualified path | Manufactured in IATF 16949-certified facilities with PPAP capability-enabling use in automotive body electronics requiring change-controlled supply. |

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, hFE = 30–120 - higher voltage rating but lower current and gain. | Better suited for high-voltage flyback snubbers; insufficient for 5A load switching. | Select only if system requires >-20V blocking with lower current demand and no thermal derating constraints. |
| 2DB1386Q-13 | Same package and structure, but hFE = 120–270 - lower minimum gain and tighter max limit than 2DB1386R-13. | Acceptable where base drive margin is ample and gain variation is less critical (e.g., simple on/off control). | Choose when cost sensitivity outweighs need for higher guaranteed hFE in closed-loop current regulation. |
Compared with MJD127G and 2DB1386Q-13, the 2DB1386R-13 uniquely balances -5A current, -20V rating, and 180–390 hFE range-making it optimal for thermally constrained, high-gain-stability applications like automotive load switching and precision linear regulation.

FAQ
Is 2DB1386R-13 AEC-Q101 qualified?
No, the 2DB1386R-13 itself is not pre-qualified to AEC-Q101, but Diodes states it is manufactured in IATF 16949-certified facilities and supports PPAP documentation upon request-enabling customer-led qualification for automotive applications requiring specific change control.
What is the recommended PCB layout for thermal performance?
Use a minimum 15mm × 15mm single-sided 1 oz copper pour connected directly to the exposed collector pad (Pin 3); include ≥4 thermal vias (0.3mm diameter) under the pad tied to inner-layer ground or power planes to achieve the rated 1W power dissipation at TA = +25°C.
How does 2DB1386R-13 differ from 2DB1386Q-13?
The 2DB1386R-13 has higher guaranteed hFE (180–390 vs. 120–270 for Q-grade) at IC = -0.5A/VCE = -2V, reflecting tighter binning for applications needing consistent current gain-such as analog current mirrors or feedback amplifiers where gain tolerance impacts accuracy.
Can 2DB1386R-13 replace an NPN transistor in circuit design?
No-it is a PNP device with opposite polarity and current flow direction; direct substitution would invert logic and violate biasing conditions. Use its complementary NPN counterpart 2DD2098 for matched pair designs or redesign bias networks to accommodate PNP topology.
