Product details
Overview
BAV23QA from Nexperia is a dual common cathode high-voltage switching diode in a DFN1010D-3 (SOT1215) package, rated for 200 V reverse voltage, 50 ns reverse recovery time, and 330 mA forward current per diode. It serves as a compact, AEC-Q101-qualified clamping and polarity protection device in automotive power supply rails and DC-DC converter feedback paths.
For engineers reviewing the BAV23QA datasheet, BAV23QA pinout, BAV23QA application, or BAV23QA equivalent, this page delivers verified electrical parameters, thermal resistance values (Rth(j-a) = 355 K/W), AOI-compatible packaging details, and validated automotive-grade substitution guidance - all grounded in Nexperia's 2018 product data sheet.
Technical Context
The BAV23QA integrates two independent silicon switching diodes sharing a single cathode terminal, enabling space-efficient dual-path clamping or reverse-polarity protection without discrete pairing. Its ultra-thin 0.37 mm profile and side-wettable DFN1010D-3 footprint support high-density PCB layouts and automated optical inspection.
Designed for stable high-speed switching up to 50 ns trr and low leakage (≤100 nA at 200 V), it operates reliably across −55 °C to +150 °C ambient with junction temperature limited to 150 °C. Thermal performance is defined for both standard FR4 mounting (Rth(j-a) = 355 K/W) and enhanced cathode-pad layouts (Rth(j-sp) = 45 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 200 V - supports clamping in 12 V/24 V automotive systems with ≥2× safety margin against transients. |
| Reverse Recovery Time (trr) | 50 ns - enables reliable operation in PWM frequencies up to ~2 MHz without excessive switching loss. |
| Forward Voltage (VF) | 1.25 V @ 200 mA - minimizes conduction loss in low-duty-cycle protection paths while maintaining thermal headroom. |
| Reverse Leakage (IR) | 100 nA @ 200 V - ensures negligible standby current in battery-backed or always-on circuits. |
| Diode Capacitance (Cd) | 2 pF @ 0 V - preserves signal integrity in high-frequency sensing or RF-coupled clamp nodes. |
| Package | DFN1010D-3 (SOT1215), 1.1 × 1.0 × 0.37 mm - enables 0.75 mm pitch routing and AOI-compatible solder joint verification. |
| Thermal Resistance (Rth(j-a)) | 355 K/W - defines maximum power dissipation (350 mW) on standard FR4 with single-sided copper. |
Pinout & Package
Encapsulated in a leadless, ultra-small DFN1010D-3 (SOT1215) plastic package with visible and solderable side pads, the BAV23QA features a 0.37 mm height and 0.75 mm pin pitch. The package includes a thermal-enhanced cathode pad optimized for heat transfer to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode path; connects to protected line or switching node requiring unidirectional conduction. |
| 2 | Anode (Diode 2) | Independent input node for second diode path; allows dual-rail clamping or redundant polarity protection. |
| 3 & 4 | Common Cathode | Shared output/return terminal; must be routed to ground or reference rail with adequate copper area for thermal and current handling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood applications including engine control units and body electronics modules. |
| Ultra-low profile (0.37 mm) | Enables stacking beneath connectors or in ultra-thin modules where Z-height is constrained to <0.4 mm. |
| Side-wettable leads | Permits automated optical inspection of solder fillets on all four terminals - critical for zero-defect automotive manufacturing. |
| Low capacitance (2 pF) | Reduces signal distortion in high-speed data line clamping (e.g., LIN bus transient suppression) without loading. |
Applications
| Automotive Power Rail Protection | DC-DC Converter Feedback Clamping |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and jump-start transients up to ±100 V. IC Role / Device Role / Timing Role: Dual-diode common-cathode configuration provides bidirectional clamping when paired with TVS, or unidirectional reverse polarity blocking. Use Value: 200 V VR rating and 50 ns trr ensure fast response to ISO 7637-2 Pulse 5a/b events without latch-up or thermal runaway. |
Use Scenario: Clamping feedback voltage nodes in isolated flyback or forward converters operating above 100 kHz. IC Role / Device Role / Timing Role: Fast-switching diode placed across optocoupler input or error amplifier reference to suppress ringing and overshoot. Use Value: 2 pF capacitance avoids phase shift in compensation networks; 1.25 V VF limits bias current error in precision feedback paths. |
| Industrial Sensor Signal Conditioning | Reverse Polarity Protection for IoT Edge Nodes |
|
Use Scenario: Protecting analog front-ends of pressure or temperature sensors connected to long cables exposed to ESD and inductive kick. IC Role / Device Role / Timing Role: High-speed switching diode used in low-leakage voltage clamp topology at sensor input pins. Use Value: 100 nA IR at 200 V prevents DC offset drift in µA-level sensor bias currents; 50 ns trr avoids pulse distortion during ESD events. |
Use Scenario: Preventing damage from incorrect battery insertion in battery-powered smart meters and asset trackers. IC Role / Device Role / Timing Role: Common-cathode dual diode configured as OR-ing element or series blocking switch in power input stage. Use Value: 330 mA per diode rating supports >300 mA peak loads; 0.37 mm height fits under compact battery holders and sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV23S | Same die, but in SOT323 package (1.3 × 1.3 × 0.95 mm); Rth(j-a) = 420 K/W; no side-wettable leads. | Lacks AOI capability and thermal performance; suitable only for non-automotive, lower-power designs. | Select when board space allows larger footprint and automotive qualification is not required. |
| NSR20F20NXT5G | 200 V, 200 mA Schottky diode in SOD-923; VF = 0.55 V; trr not specified (Schottky = inherently fast); IR = 10 µA @ 200 V. | Higher leakage (100× BAV23QA) limits use in battery-critical applications; lower VF reduces conduction loss. | Prefer for efficiency-critical, low-leakage-tolerant DC-DC outputs where trr is secondary to VF. |
Compared with BAV23S and NSR20F20NXT5G, the BAV23QA uniquely combines AEC-Q101 qualification, side-wettable DFN1010D-3 packaging, and sub-100 nA leakage - making it the only choice for space-constrained, zero-defect automotive clamping where thermal and reliability margins are non-negotiable.

FAQ
Is the BAV23QA suitable for reverse polarity protection in 24 V truck systems?
Yes. With a 200 V reverse voltage rating and 330 mA per diode continuous forward current, the BAV23QA supports reverse-blocking configurations in 24 V nominal systems subject to ISO 16750-2 load dump transients up to 35 V. Its 150 °C max junction temperature and AEC-Q101 qualification confirm suitability for under-hood deployment.
Can the BAV23QA replace a single discrete diode in existing SOT23 designs?
No. The BAV23QA is a dual-diode device in DFN1010D-3 (3-terminal, common cathode), incompatible with SOT23 pinout or footprint. Direct replacement requires PCB redesign to accommodate its 1.1 × 1.0 mm body, 0.75 mm pitch, and dual-anode layout - though it eliminates two separate SOT23 placements.
What is the maximum allowable power dissipation at 85 °C ambient?
At 85 °C ambient, derating applies: Ptot = 350 mW × (1 − (85 − 25)/125) = 210 mW. This assumes standard FR4 mounting (Rth(j-a) = 355 K/W). For higher dissipation, use the enhanced cathode pad layout (Rth(j-sp) = 45 K/W) to shift thermal path toward PCB copper.
Does the BAV23QA require special reflow profile considerations?
Yes. As a DFN1010D-3 package with side-wettable leads, it requires precise stencil design (0.125 mm thickness, 0.35 mm aperture for anode pads, 0.45 mm for cathode) and a peak reflow temperature of 260 °C for ≤30 seconds. Reflow must follow Nexperia's sot1215_fr footprint guidelines to ensure coplanar solder joints and void-free cathode pad wetting.
