Product details
Overview
BAV23S-Q from Nexperia is a dual high-voltage switching diode in SOT23 package, configured as two independent diodes sharing a common terminal (pin 3 = K1/A2). It delivers VRRM = 250 V, trr ≤ 50 ns, Cd ≤ 2 pF, and IF(max) = 125 mA per diode, qualified to AEC-Q101 for automotive high-speed switching at up to 200 V reverse bias.
For engineers reviewing the BAV23S-Q datasheet, BAV23S-Q pinout, BAV23S-Q application, or BAV23S-Q equivalent, this device supports high-reliability voltage-clamped flyback snubbing, bidirectional transient suppression in 12 V/24 V automotive power rails, and fast logic-level signal steering where low capacitance and sub-50 ns recovery are critical.
Technical Context
The BAV23S-Q integrates two discrete high-voltage switching diodes in a single SOT23-3 package with shared terminal architecture: pin 1 is anode of D1, pin 2 is cathode of D2, and pin 3 serves as both cathode of D1 and anode of D2 - enabling series, parallel, or common-cathode/anode configurations without external interconnects. Its silicon epitaxial construction ensures stable trr performance across −40 °C to +150 °C junction temperature.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements including HTGB, HTRB, and ESD-HBM ≥ 2 kV. Thermal resistance Rth(j-a) = 500 K/W on FR4 PCB enables sustained operation at Ptot = 250 mW with Tj ≤ 150 °C under double-diode load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V repetitive peak reverse voltage - supports clamping in 24 V automotive systems with 10× safety margin over nominal bus transients |
| trr | ≤ 50 ns reverse recovery time - enables clean switching at >1 MHz in DC-DC snubber and flyback auxiliary winding rectification |
| Cd | ≤ 2 pF diode capacitance at 0 V - minimizes signal coupling and timing skew in high-frequency logic interface protection |
| IF | 125 mA continuous forward current per diode - sufficient for LED indicator drive and low-power signal routing in body control modules |
| IR | ≤ 100 nA reverse leakage at 200 V - ensures negligible standby current in always-on automotive wake-up circuits |
| Ptot | 250 mW total power dissipation - allows dual-diode operation on standard FR4 PCB without heatsinking below 70 °C ambient |
Pinout & Package
Encapsulated in SOT23 (TO-236AB), a 3-terminal surface-mount plastic package measuring 2.9 mm × 1.3 mm × 1.0 mm with 1.9 mm lead pitch and standard FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first diode's forward conduction path; connects to high-side switch drain or inductive load return |
| 2 | Cathode of Diode 2 (K2) | Output node for second diode's forward conduction; used for clamp-to-rail or bidirectional ESD path termination |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1, A2) | Shared terminal enabling compact dual-diode topologies - e.g., common-cathode OR-ing or back-to-back AC coupling |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| ON Semiconductor MMBD231L | VRRM = 200 V, trr = 50 ns, Cd = 2.5 pF, not AEC-Q101 qualified | Limited to industrial/commercial use; lacks automotive qualification and 50 V reverse margin | Select when cost sensitivity outweighs automotive compliance and higher VRRM is unnecessary |
| Diodes Incorporated BAV23C | VRRM = 250 V, trr = 50 ns, Cd = 2 pF, AEC-Q101 qualified, but SOT323 package (smaller footprint, higher thermal resistance) | SOT323 reduces PCB area but increases Rth(j-a) to 600 K/W - limits power handling in thermally constrained layouts | Select when board space is critical and thermal derating to 180 mW is acceptable |
Compared with MMBD231L and BAV23C, the BAV23S-Q uniquely balances AEC-Q101 compliance, 250 V rating, 500 K/W thermal resistance on FR4, and SOT23 manufacturability - making it optimal for production automotive modules requiring validated reliability and assembly compatibility.

FAQ
What is the maximum continuous forward current per diode in the BAV23S-Q?
The BAV23S-Q supports 125 mA continuous forward current per diode when both diodes are simultaneously conducting (double-diode loaded condition), as specified in Table 5 under "IF forward current" with derating applied per Figure 5. This rating assumes operation on standard FR4 PCB at Tamb ≤ 25 °C.
Can the BAV23S-Q be used in a common-anode configuration?
Yes - pin 3 functions as both cathode of diode 1 and anode of diode 2, enabling common-anode, common-cathode, or series-connected configurations. For common-anode use, connect pin 3 to VCC, pin 1 to signal A, and pin 2 to signal B, allowing either diode to conduct toward VCC independently.
Is the BAV23S-Q suitable for 48 V mild-hybrid vehicle systems?
No - while its VRRM = 250 V exceeds typical 48 V system transients, the device is rated for 200 V operating reverse voltage (VR) and qualified for 12 V/24 V automotive applications per AEC-Q101 test conditions. Use only in 48 V systems after full validation against ISO 21782-2 pulse requirements and thermal modeling.
How does the shared-pin architecture affect PCB layout compared to discrete diodes?
The shared-pin (pin 3 = K1/A2) eliminates one net connection and reduces pad count by 25%, simplifying routing in tight spaces like ECU sensor interfaces. Layout must observe minimum solder mask clearance (0.15 mm) and use the reflow footprint in Figure 8 to ensure coplanarity and avoid tombstoning during SMT assembly.
