Product details
Overview
2DB1132R-13 from Diodes Incorporated is a 32V PNP power switching transistor in SOT89 package, rated for -1A continuous collector current, -32V VCEO, and 1W power dissipation at 25°C ambient with 15mm×15mm copper pad. It delivers hFE = 180–390 at IC = -100mA/VCE = -3V and VCE(sat) = -125mV (typ) at IC = -500mA/IB = -50mA, enabling medium-power DC switching in industrial power supplies and LED drivers.
For engineers reviewing the 2DB1132R-13 datasheet, 2DB1132R-13 pinout, 2DB1132R-13 application, or 2DB1132R-13 equivalent, key selection criteria include verified PNP switching capability, thermal performance on defined PCB copper areas, JEDEC-compliant reliability, and direct compatibility with automated SMT assembly processes.
Technical Context
This device operates as a medium-power PNP bipolar junction transistor optimized for linear amplification and saturated switching. Its high hFE range (180–390) supports low-base-drive designs, while its -32V VCEO and -40V VCBO ratings enable use in 24V rail systems with margin. The SOT89 package features an exposed collector pad thermally coupled to PCB copper for enhanced heat dissipation.
Thermal resistance varies with copper area: RθJA = 125°C/W (15×15 mm), 83°C/W (25×25 mm), or 60°C/W (50×50 mm). ESD robustness includes 4kV HBM and 400V MM ratings per JEDEC JESD22-A114/A115, supporting handling in standard manufacturing environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -32 V - Maximum safe collector-emitter voltage under open-base conditions; defines usable voltage headroom in 24V DC systems. |
| IC (cont) | -1 A - Continuous collector current rating; determines maximum load drive capability without derating at 25°C ambient. |
| hFE | 180–390 - DC current gain at IC = -100mA/VCE = -3V; enables precise base resistor sizing for predictable saturation. |
| VCE(sat) | -125 mV (typ) at IC = -500mA/IB = -50mA - Low saturation voltage reduces conduction loss and self-heating in switching applications. |
| RθJA | 125 °C/W - Junction-to-ambient thermal resistance on 15×15 mm 1oz Cu; sets temperature rise per watt dissipated in minimal layout. |
| fT | 190 MHz - Transition frequency at IE = -50mA/VCE = -5V/30MHz; confirms suitability for audio-frequency switching, not RF. |
| ESD HBM | 4,000 V - Human Body Model rating per JESD22-A114; supports robust handling during board assembly and test. |
Pinout & Package
SOT89 package with molded green plastic case, UL 94V-0 flammability rating, matte tin-plated leads, and exposed collector pad for thermal conduction to PCB. Weight: 0.055 g.

| Collector (C) | Power output terminal | Exposed metal pad soldered to PCB copper; primary thermal path and main current return node. |
Key Features
| Feature | Design Value |
|---|---|
| High hFE range | 180–390 ensures stable switching with low base drive current, reducing control circuit power and component count. |
| Low VCE(sat) | -125 mV typ at IC = -500mA minimizes conduction loss and improves efficiency in battery-powered or thermally constrained systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP power switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD112-13 | Higher VCEO (-40V), lower hFE (30–120), TO-252 package | Requires larger PCB footprint and different thermal layout; better for higher-voltage 36V+ systems | Select when >32V blocking or TO-252 mechanical fit is required; verify base drive sufficiency due to lower gain. |
| ZTX788B | Higher VCEO (-45V), similar hFE (200–450), SOT-223 package | Greater thermal mass but no exposed collector pad; RθJA ~100°C/W on same copper area | Choose for improved voltage margin and legacy SOT-223 footprint compatibility; expect slightly higher thermal resistance. |
Compared with MJD112-13 and ZTX788B, the 2DB1132R-13 offers optimal balance of SOT89 compactness, high gain, low saturation voltage, and JEDEC-qualified reliability-making it preferred for space-constrained 24V industrial and automotive modules where thermal performance and manufacturability are critical.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The 2DB1132R-13 has an operating junction temperature range of -55°C to +150°C. For continuous operation, the maximum junction temperature must not exceed +150°C, which requires appropriate PCB copper area and ambient temperature control based on its RθJA values (e.g., 125°C/W on 15×15 mm Cu).
Is this part qualified for automotive applications?
The 2DB1132R-13 is JEDEC-qualified and meets AEC-Q101 stress test requirements for high reliability. While not an automotive-grade Q-suffix part, it is suitable for non-safety-critical automotive interior applications; Diodes offers dedicated AEC-Q101 qualified variants (e.g., 2DB1132QR) for PPAP-capable production.
How does the SOT89 exposed collector pad affect thermal design?
The exposed collector pad serves as the primary thermal path from die to PCB. When soldered to ≥15 mm² of 1oz copper, it achieves RθJA = 125°C/W; increasing copper area to 50×50 mm reduces RθJA to 60°C/W, directly lowering junction temperature under identical power dissipation.
Can this transistor be used in linear amplifier configurations?
Yes-the 2DB1132R-13 supports linear operation with specified hFE, VCE(sat), and fT = 190 MHz. Its gain stability across temperature and low distortion at moderate frequencies make it suitable for audio preamplifiers or sensor signal conditioning, provided thermal limits and SOA constraints are observed.
