Product details
Overview
BAS20DWQ-13 from Diodes Incorporated is an automotive-grade dual high-voltage switching diode in SOT363 package, featuring 200 V repetitive peak reverse voltage (VRRM), 400 mA forward current (IF), and 50 ns reverse recovery time (tRR). It serves as a fast-switching, low-leakage signal routing or clamping element in power supply snubbers, ESD protection circuits, and automotive sensor interface front-ends.
For engineers reviewing the BAS20DWQ-13 datasheet, BAS20DWQ-13 pinout, BAS20DWQ-13 application, or BAS20DWQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max operating temperature, dual-common-cathode configuration, and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
This dual diode integrates two independent silicon junctions in a single SOT363 package with shared cathode terminals, enabling compact bidirectional clamping or dual-path rectification. Its 200 V VRRM and 100 nA IR at 150 °C support reliable operation in 12 V/24 V automotive subsystems under transient overvoltage conditions.
The 50 ns tRR and 5.0 pF CT at 0 V enable use in high-frequency signal conditioning up to ~100 MHz, while its 200 mW power dissipation rating requires thermal derating above +25 °C ambient per the published derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands repetitive 200 V reverse transients without breakdown in automotive load-dump scenarios |
| IF | 400 mA - Continuous forward current per diode; supports dual-diode parallel operation at full rating |
| tRR | 50 ns - Enables clean switching in PWM-controlled DC-DC feedback paths and signal edge detection |
| IR @ 150 °C | 100 nA - Ultra-low leakage preserves signal integrity in high-impedance sensor bias networks |
| CT @ 0 V | 5.0 pF - Minimizes capacitive loading on RF-sensitive analog inputs and clock lines |
| TJ Range | −65 to +150 °C - Fully rated for under-hood automotive environments including engine control units |
Pinout & Package
SOT363 is a 6-pin, surface-mount plastic package with dual-diode topology and common cathode configuration. Pin 1 and Pin 2 are anode terminals for D1 and D2 respectively; Pins 3 and 6 are tied internally to the common cathode; Pins 4 and 5 are unused (NC) and electrically isolated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first switching path; connects to signal source or inductive flyback node |
| Pin 2 | Anode of Diode 2 | Independent input node for second path; enables dual-rail clamping or redundancy |
| Pins 3 & 6 | Common Cathode | Shared output node; must be routed to ground or reference rail with low-inductance trace |
| Pins 4 & 5 | No Connect (NC) | Internally unconnected; left floating per datasheet - no PCB pad connection required |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine management, body control modules, and ADAS sensors |
| Lead-free & Green | Meets RoHS 3 and halogen/antimony-free requirements (<900 ppm Br/Cl, <1000 ppm Sb) |
| Fast tRR = 50 ns | Reduces switching losses and ringing in 100 kHz–1 MHz DC-DC converters and signal clamp circuits |
| Low IR = 100 nA @ 150 °C | Prevents drift in precision voltage references and thermistor bias networks across full temperature range |
| SOT363 footprint | Enables high-density placement with standard 0.65 mm pitch reflow profiles and AOI-compatible marking |
Applications
| Automotive Load-Dump Protection | High-Speed Signal Clamping |
|---|---|

Use Value: 200 V VRRM and 150 °C TJ ensure survival through repeated load-dump cycles without parameter shift. | Use Scenario: Limiting analog sensor output swing (e.g., oxygen sensor, knock sensor) to MCU ADC input range. IC Role / Device Role / Timing Role: Fast-turn-on voltage limiter preventing ADC saturation during transient spikes. Use Value: 50 ns tRR and 5.0 pF CT preserve signal fidelity up to 10 MHz without phase distortion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-voltage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS20DW-13 | Commercial-grade version; identical electrical specs but not AEC-Q101 qualified | Not suitable for automotive production; acceptable for prototyping or non-safety-critical industrial use | Select only if AEC-Q101 compliance is not required and cost sensitivity outweighs qualification assurance |
| MMBD2004-7-F | Same SOT363 package, 200 V VRRM, but tRR = 75 ns and IR = 200 nA @ 150 °C | Higher leakage and slower recovery limit use in precision analog or high-frequency snubbers | Acceptable for basic clamping where timing margin exists; verify thermal performance under sustained 100 °C operation |
Compared with BAS20DW-13 and MMBD2004-7-F, BAS20DWQ-13 uniquely delivers AEC-Q101 validation, tighter IR spec, and faster tRR, making it the sole choice for production automotive systems requiring long-term reliability under thermal stress.

FAQ
What is the pin configuration of BAS20DWQ-13?
The BAS20DWQ-13 uses a dual-anode, common-cathode arrangement in SOT363: Pin 1 = Anode 1, Pin 2 = Anode 2, Pins 3 & 6 = tied common cathode, Pins 4 & 5 = no-connect. This layout supports independent signal routing with shared return path and is confirmed in the DS30617 Rev. 13 schematic diagram.
Is BAS20DWQ-13 suitable for 24 V commercial truck applications?
Yes - its 200 V VRRM, −65 to +150 °C operating range, AEC-Q101 qualification, and PPAP capability meet ISO 16750-2 requirements for 24 V truck electrical systems, including load-dump immunity and extended temperature cycling.
How does BAS20DWQ-13 differ from BAS21DWQ-13?
BAS21DWQ-13 has higher 250 V VRRM and 200 V VRWM but identical package, thermal specs, and AEC-Q101 qualification. Use BAS20DWQ-13 where 200 V margin suffices and lower capacitance (5.0 pF vs. 6.0 pF typical) is preferred for high-frequency signal paths.
Can BAS20DWQ-13 replace single-diode packages like 1N4148W in automotive designs?
No - although electrically comparable per diode, BAS20DWQ-13 integrates two diodes with shared cathode and NC pins. Direct replacement requires verifying PCB layout compatibility, thermal coupling between diodes, and whether dual functionality is needed versus discrete placement.
