Product details
Overview
2DA1213O-13 from Diodes Incorporated is a 50V PNP power switching transistor in SOT89 package, rated for -2A continuous collector current and -50V VCEO, designed for high-reliability DC-DC converter switching, automotive load control, and industrial relay drivers where robust saturation performance and thermal stability are required.
For engineers reviewing the 2DA1213O-13 datasheet, 2DA1213O-13 pinout, 2DA1213O-13 application, or 2DA1213O-13 equivalent, key selection criteria include verified -0.5V VCE(sat) at -1A/-50mA drive, 70–140 hFE range at -500mA, SOT89 thermal resistance (RθJL = 18.3°C/W), and JEDEC-qualified reliability for non-automotive industrial use.
Technical Context
This PNP bipolar junction transistor operates as a medium-power, low-saturation switch with fixed emitter-base and collector-base breakdown limits (-6V and -50V respectively). Its gain-bandwidth product of 160MHz enables fast switching up to ~100kHz in hard-switched topologies.
Thermal design relies on the exposed collector pad in SOT89: RθJL = 18.3°C/W confirms direct heat conduction to PCB copper, while RθJA = 125°C/W applies only under defined 15mm×15mm FR4 mounting conditions - not typical for high-current operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -50V - Maximum safe collector-emitter voltage before avalanche; supports 24V/36V rail switching with margin. |
| IC (cont.) | -2A - Continuous collector current rating; defines max steady-state load drive capability. |
| VCE(sat) | -0.5V @ -1A/-50mA - Low saturation voltage minimizes conduction loss in high-duty-cycle switches. |
| hFE | 70–140 @ -500mA/-2V - Confirmed DC current gain range ensures predictable base drive sizing. |
| fT | 160MHz - Enables sub-100ns switching transitions; suitable for PWM frequencies ≤100kHz. |
| RθJL | 18.3°C/W - Thermal resistance from junction to leads; validates efficient heat transfer via collector pad. |
Pinout & Package
Package: SOT89 - surface-mount plastic package with exposed collector tab for thermal dissipation; dimensions per JEDEC TO-243AA standard (D = 4.50mm, E = 2.50mm, H = 4.10mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Emitter) | Emitter terminal | Reference node for base drive; connected to higher potential in PNP switch configuration. |
| Pin 2 (Base) | Control input | Receives negative current to turn on; requires -50mA for full saturation at -1A load. |
| Pin 3 (Collector) | Switched output | Exposed metal tab - electrically and thermally connected to collector; must be soldered to large copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| High BVCEO | -50V rating provides 100% margin over 24V systems and compatibility with 36V industrial rails. |
| Stable hFE across temperature | hFE remains ≥20 at -2A and 150°C - ensures reliable switching under thermal stress. |
| Low VBE(sat) | -1.2V @ -1A/-50mA - reduces base drive power loss and simplifies driver stage design. |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant (Br+Cl <1500ppm, Sb <1000ppm) - meets modern environmental compliance. |
Applications
| DC-DC Converter Switch | Automotive Load Control |
|---|---|
Use Scenario: High-side switch in non-synchronous buck converter for 12V-to-5V conversion in infotainment modules. IC Role / Device Role / Timing Role: PNP power switch controlling energy transfer during off-time; driven by complementary logic-level signal. Use Value: -0.5V VCE(sat) limits conduction loss to <125mW at 250mA load, improving efficiency over generic transistors. |
Use Scenario: Controlling 12V solenoid valves in engine management subsystems. IC Role / Device Role / Timing Role: Medium-current load switch interfacing microcontroller GPIO to inductive load. Use Value: -50V VCEO withstands load-dump transients up to 40V, eliminating need for external clamping in many cases. |
| Industrial Relay Driver | LED String Power Switch |
Use Scenario: Driving 24V coil relays in programmable logic controller (PLC) output modules. IC Role / Device Role / Timing Role: Solid-state replacement for mechanical relay contacts; switched at ≤10Hz. Use Value: -2A IC rating supports 1.5A relay coils with 33% derating margin, ensuring long-term reliability. |
Use Scenario: On/off control of 350mA LED strings in signage and panel lighting. IC Role / Device Role / Timing Role: Constant-current bypass switch enabling dimming via PWM-controlled shunt path. Use Value: 160MHz fT allows clean 1kHz–5kHz PWM edges without ringing, reducing EMI in lighting circuits. |
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 |
|---|---|---|---|
| MJD2955RLG | Higher VCEO (-70V), lower hFE (20–70), TO-220 package | Requires heatsink for >1A continuous; better for 48V systems but less space-efficient | Select when higher voltage margin or legacy TO-220 footprint is required. |
| ZTX951 | SOT89 package, -60V VCEO, -1.5A IC, VCE(sat) = -0.6V @ -1A | Lower current rating and higher saturation voltage reduce efficiency at full load | Choose only if -60V rating is mandatory and peak current stays below 1.2A. |
Compared with MJD2955RLG and ZTX951, the 2DA1213O-13 delivers optimal balance of SOT89 compactness, -2A current handling, and -0.5V saturation voltage - making it preferred for space-constrained 24V industrial switches where thermal performance and conduction loss are critical.

FAQ
Is 2DA1213O-13 still in active production?
No - Diodes lists 2DA1213O-13 as obsolete in its ordering information table (Rev. 6-2, August 2021). However, Aetrix Electronics maintains legacy stock and offers controlled-life-cycle sourcing with full traceability, including date-code verification and JEDEC-compliant test reports.
Can 2DA1213O-13 replace 2DA1213Y-13 in new designs?
No - the 2DA1213O-13 has lower hFE (70–140 vs. 120–240 for Y version) and is obsolete. While electrically compatible in existing circuits, new designs should use the active 2DA1213Y-13 or qualified alternatives to ensure long-term supply and guaranteed parametric performance.
What is the maximum allowable PCB copper area for thermal performance?
Per DS31306 Note 5, the 125°C/W RθJA rating assumes a 15mm × 15mm × 0.6mm FR4 board with single-sided 1 oz copper. For higher current operation, the exposed collector pad must connect to ≥250 mm² of internal or external copper; doubling copper area typically improves RθJA by 15–20%.
Does 2DA1213O-13 meet AEC-Q101 requirements?
No - the datasheet explicitly states that only Q-suffix automotive-grade variants (e.g., 2DA1213Q) are AEC-Q101 qualified. The 2DA1213O-13 is JEDEC-qualified for high reliability but lacks PPAP documentation, IATF 16949 manufacturing evidence, or AEC change-control processes required for automotive use.
