Product details
Overview
2DB1132Q-13 from Diodes Incorporated is a PNP bipolar junction transistor (BJT) designed for medium-power switching and amplification, featuring -32 V VCEO, -1 A continuous collector current, 120–270 hFE at -100 mA / -3 V, and SOT89 surface-mount package. It operates reliably from -55 °C to +150 °C and is suited for DC-DC converter control stages and industrial relay drivers.
For engineers reviewing the 2DB1132Q-13 datasheet, 2DB1132Q-13 pinout, 2DB1132Q-13 application, or 2DB1132Q-13 equivalent, key selection criteria include verified VCEO rating, thermal resistance (RθJA = 83 °C/W on 25 mm × 25 mm copper), hFE binning consistency, and JEDEC-compliant ESD robustness (4 kV HBM).
Technical Context
This PNP BJT uses epitaxial planar construction with a complementary NPN counterpart (2DD1664). Its gain-bandwidth product reaches 190 MHz at -50 mA emitter current and -5 V VCE, supporting high-speed switching up to ~100 kHz in saturated-mode applications.
Thermal performance is defined across three PCB copper-area configurations: RθJA = 125 °C/W (15 mm × 15 mm), 83 °C/W (25 mm × 25 mm), and 60 °C/W (50 mm × 50 mm), enabling precise power derating in thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -32 V - Maximum safe collector-emitter voltage before avalanche breakdown under open-base conditions |
| IC (cont) | -1 A - Continuous DC collector current capability with proper heatsinking on 25 mm × 25 mm copper |
| hFE | 120–270 - DC current gain range at -100 mA IC, -3 V VCE; defines base drive requirement for saturation |
| VCE(sat) | -125 to -500 mV - Voltage drop across collector-emitter when fully saturated at -500 mA IC / -50 mA IB |
| fT | 190 MHz - Transition frequency indicating usable small-signal bandwidth in common-emitter configuration |
| RθJA | 83 °C/W - Junction-to-ambient thermal resistance on standard 25 mm × 25 mm 1 oz copper PCB, used for thermal design margining |
| ESD HBM | 4,000 V - Human Body Model robustness level per JESD22-A114, critical for handling and assembly reliability |
Pinout & Package
SOT89 package with exposed collector pad for thermal conduction; molded green plastic case (UL 94V-0), matte tin-plated leads, 0.055 g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Collector (Tab) | Power output node / heat sink interface | Exposed metal tab electrically connected to collector; must be soldered to ≥25 mm² copper area for thermal compliance |
| Base | Control input | Current-driven gate; requires -50 mA IB to saturate at -500 mA IC per datasheet test condition |
| Emitter | Reference terminal / current return path | Connected to system ground or higher-potential rail depending on switching topology (e.g., high-side switch configuration) |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage PNP switching | Rated for -32 V VCEO, enabling use in 24 V industrial bus and automotive load-switching applications |
| Automated-assembly optimized | SOT89 footprint and lead finish comply with MIL-STD-202 solderability standards for reflow and wave processes |
| JEDEC-reliable construction | Qualified to AEC-Q101 stress-test standards for high-reliability discrete transistors in harsh environments |
| Green material compliance | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb), meeting RoHS 3 and IEC 61249-2-21 |
Applications
| Industrial Relay Driver | DC-DC Converter Control |
|---|---|
Use Scenario: Driving 24 V coil relays in programmable logic controllers with microcontroller GPIO-level base control. IC Role / Device Role / Timing Role: Medium-power PNP switch providing low-saturation voltage and fast turn-off for reliable coil de-energization. Use Value: -125 mV VCE(sat) minimizes power loss during sustained on-state; 190 MHz fT ensures clean edge transitions during PWM-modulated drive. | Use Scenario: High-side switch in non-isolated buck regulator feedback loop or synchronous rectifier auxiliary control. IC Role / Device Role / Timing Role: PNP-based active clamp or gate driver stage controlling MOSFET gate voltage referenced to input rail. Use Value: -32 V VCEO supports operation across 12–28 V input ranges; hFE binning enables predictable base resistor sizing for stable switching thresholds. |
| Automotive Lighting Control | Power Supply Sequencing |
Use Scenario: Controlling LED headlamp modules in body control units where reverse-polarity protection and thermal resilience are required. IC Role / Device Role / Timing Role: High-side current switch managing load current while surviving load-dump transients up to -32 V. Use Value: -40 V VCBO and -5 V VEBO provide margin against inductive kickback and reverse-battery events in 12 V systems. | Use Scenario: Enabling/disabling downstream voltage rails in multi-rail embedded systems using sequenced enable signals. IC Role / Device Role / Timing Role: Discrete power switch implementing controlled ramp-up of supply voltages to avoid inrush current violations. Use Value: -1 A IC rating supports >500 mA rail loads; RθJA = 83 °C/W allows operation without external heatsink at ambient ≤70 °C. |
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 |
|---|---|---|---|
| 2DB1132R-13 | Higher hFE (180–390), active status vs. obsolete Q-grade | Same SOT89 footprint and absolute ratings; preferred for new designs requiring tighter gain tolerance | Select R-grade for improved current gain consistency and long-term supply assurance |
| MJD122G | TO-252 package, -100 V VCEO, -1.5 A IC, lower hFE (20–100) | Higher voltage margin but larger footprint; suited for higher-energy transient environments | Choose MJD122G only if -100 V rating or TO-252 thermal mass is required; not drop-in compatible |
Compared with 2DB1132R-13, the Q-grade offers identical electrical specs but lacks ongoing production support; versus MJD122G, it trades voltage headroom and package size for smaller board area and better gain predictability in 24 V systems.

FAQ
Is 2DB1132Q-13 still in production?
No-2DB1132Q-13 is marked obsolete in Diodes' official ordering information. Only 2DB1132R-13 and 2DB1132R-13R remain active. Aetrix maintains limited legacy stock of Q-grade for repair and maintenance of existing designs, with full traceability and date-code documentation.
What is the difference between 2DB1132Q-13 and 2DB1132R-13?
The sole functional difference is DC current gain: Q-grade specifies hFE = 120–270, while R-grade specifies 180–390 at -100 mA / -3 V. Both share identical absolute maximum ratings, thermal characteristics, SOT89 package, and pinout. R-grade is recommended for new designs due to active status and tighter gain distribution.
Can 2DB1132Q-13 replace 2DB1132P-13?
Yes-both share identical electrical specifications except hFE: P-grade is 82–180, Q-grade is 120–270. They are mechanically and electrically interchangeable in SOT89 footprint. However, P-grade is also obsolete, and neither should be used in new designs without verifying gain-dependent circuit margins.
Does 2DB1132Q-13 meet AEC-Q101 requirements?
Yes-the datasheet states qualification to JEDEC standards "as references in AEC-Q", and Diodes explicitly lists this part family under its AEC-Q101-qualified discrete transistors. It is manufactured in IATF 16949-certified facilities, though the Q-suffix does not denote automotive grade-automotive variants use dedicated part numbers (e.g., 2DB1132RQ).
