Product details
Overview
BAV23-Q from Nexperia is a dual high-voltage switching diode in SOT143B package, configured as two independent silicon switching diodes with 250 V repetitive peak reverse voltage (VRRM), ≤50 ns reverse recovery time (trr), and ≤2 pF capacitance per diode-used for high-speed, high-voltage switching in automotive power supply rails and ECU input protection circuits.
For engineers reviewing the BAV23-Q datasheet, BAV23-Q pinout, BAV23-Q application, or BAV23-Q equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, SOT143B footprint details, and automotive-grade reliability data required for robust high-voltage discrete selection.
Technical Context
The BAV23-Q integrates two isolated high-voltage switching diodes in a single 4-pin SOT143B package, enabling compact dual-path clamping or series switching without cross-coupling. Each diode supports 250 V VRRM and exhibits fast trr ≤ 50 ns under IF = 10 mA / IR = 10 mA test conditions at 25 °C ambient.
Its low 2 pF junction capacitance and 100 nA reverse leakage at VR = 200 V support stable high-frequency operation in snubber networks and flyback clamp circuits. Qualified to AEC-Q101, it sustains 150 °C junction temperature and operates across −65 °C to +150 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - Enables use in 200 V DC bus clamping and 170 VAC rectified line applications without breakdown risk. |
| trr | ≤50 ns - Supports switching frequencies up to ~10 MHz in snubbers and high-side gate drive clamp circuits. |
| Cd | ≤2 pF - Minimizes capacitive loading on high-impedance signal paths and preserves rise/fall time integrity. |
| IR @ VR = 200 V | ≤100 nA - Ensures negligible leakage current in battery-backed or ultra-low-power standby circuits. |
| IFRM | 625 mA - Handles repetitive surge currents in transient suppression and inductive load freewheeling. |
| Ptot | 250 mW - Requires thermal derating above 25 °C ambient; supports 125 mA continuous forward current at Tamb ≤ 25 °C. |
| AEC-Q101 | Qualified - Validated for automotive underhood and body-control module applications per stress test standard. |
Pinout & Package
SOT143B is a 4-lead surface-mount plastic package measuring 2.9 mm × 1.3 mm × 1.0 mm with 1.9 mm lead pitch and gull-wing terminations. Thermal resistance Rth(j-a) is 500 K/W on FR4 PCB with single-sided copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | Cathode of Diode 1 - Connects to positive rail or switched node when used as high-side clamp or freewheel path. |
| 2 | K2 | Cathode of Diode 2 - Independent cathode terminal enables dual-rail clamping or separate signal path isolation. |
| 3 | A2 | Anode of Diode 2 - Paired with Pin 2 for second diode; allows reverse-biased configuration for bidirectional protection. |
| 4 | A1 | Anode of Diode 1 - Paired with Pin 1; supports common-anode or common-cathode topologies depending on PCB routing. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 50 ns ensures minimal switching loss and clean edge fidelity in PWM-driven inductive loads. |
| Low junction capacitance | Cd ≤ 2 pF prevents signal distortion in RF detector or high-frequency sampling circuits. |
| AEC-Q101 qualification | Validated for automotive underhood environments including thermal cycling, humidity, and mechanical shock. |
| Small SMD footprint | SOT143B saves >40% board area versus SOIC-8 dual diodes while maintaining thermal performance via solder-point conduction. |
| Low leakage current | IR ≤ 100 nA at 200 V enables reliable hold-up in high-impedance bias networks and sensor reference dividers. |
Applications
| Automotive Power Supply Clamp | Industrial Flyback Snubber |
|---|---|
|
Use Scenario: Suppressing inductive kickback from solenoid drivers in engine control units. IC Role / Device Role / Timing Role: Dual-diode clamp placed across coil terminals to absorb energy during MOSFET turn-off. Use Value: 250 V VRRM withstands 200 V transients; 50 ns trr ensures rapid recombination before next switching cycle. |
Use Scenario: Damping voltage spikes in offline flyback converters operating at 65–100 kHz. IC Role / Device Role / Timing Role: Fast-recovery diode in RC snubber network across primary winding. Use Value: 2 pF capacitance avoids resonance with snubber resistor; low IR maintains efficiency at light load. |
| DC Bus Overvoltage Protection | High-Voltage Signal Conditioning |
|
Use Scenario: Protecting microcontroller I/O pins from 150–200 V surges in battery management system monitoring lines. IC Role / Device Role / Timing Role: Series-connected diode limiting input voltage swing to safe logic levels. Use Value: 250 V VRRM provides 50 V margin over max expected transient; 100 nA IR avoids loading precision dividers. |
Use Scenario: Level-shifting and clamping analog signals in industrial PLC input modules handling ±100 V field inputs. IC Role / Device Role / Timing Role: Dual-diode pair used for bidirectional rail-to-rail clamping before ADC front-end. Use Value: Matched trr and Cd ensure symmetrical clipping response; SOT143B allows tight layout near connector entry point. |
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 |
|---|---|---|---|
| BAV21W (Nexperia) | Single diode, same VRRM (250 V), but trr = 50 ns and Cd = 4 pF - higher capacitance, no dual configuration. | Lacks dual-diode integration; requires two devices for same functionality, increasing board area and assembly cost. | Select only if space permits discrete placement and dual-channel coordination is unnecessary. |
| STTH2R06 (STMicroelectronics) | Single 600 V diode, trr = 35 ns, IF = 2 A - higher voltage rating and current capability, but larger SOD-123 package. | Not pin-compatible; unsuitable for space-constrained dual-path designs; better for high-current single-rail applications. | Choose when VRRM > 250 V or IF > 125 mA is required; avoid where dual-diode topology or SOT143B footprint is mandatory. |
Compared with BAV21W and STTH2R06, the BAV23-Q uniquely delivers dual-channel 250 V switching in a miniature SOT143B package with sub-2 pF capacitance-making it optimal for automotive ECU space budgets and high-frequency snubber layouts where integration and parasitic minimization are critical.

FAQ
Is BAV23-Q suitable for 24 V automotive systems with load-dump transients?
Yes. With 250 V VRRM and AEC-Q101 qualification, the BAV23-Q withstands ISO 7637-2 Load Dump Pulse 5a (up to 120 V) and offers 130 V margin for design safety. Its 50 ns trr ensures effective clamping during fast-rising transients, and its 150 °C Tj rating supports underhood deployment.
Can BAV23-Q be used in common-cathode configuration?
Yes. Pins 1 and 2 are independent cathodes (K1, K2); tying them together forms a common-cathode dual-anode configuration. This is valid for applications like dual-rail voltage clamping or OR-ing circuits, provided thermal limits (250 mW total Ptot) are observed with combined current flow.
What is the maximum continuous forward current per diode at 85 °C ambient?
Per Figure 5 in the datasheet, the derated IF at Tamb = 85 °C is approximately 75 mA per diode when mounted on FR4 with standard footprint. This assumes single-diode loading; double-diode loading reduces usable current further due to shared thermal resistance.
Does BAV23-Q require special PCB layout considerations for thermal performance?
Yes. To achieve rated 250 mW dissipation, the SOT143B must be mounted on FR4 with tin-plated copper, using the recommended reflow footprint (Fig. 8). Avoid thermal isolation; maximize copper pour under the package and connect pins 1–4 to internal ground/power planes to leverage Rth(j-sp) = 360 K/W.
