Product details
Overview
BAV23S 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, and Cd ≤ 2 pF per diode, enabling fast, low-capacitance switching in high-voltage DC-DC converters and flyback snubbers.
For engineers reviewing the BAV23S datasheet, BAV23S pinout, BAV23S application, or BAV23S equivalent, this device is selected for high-speed, high-voltage discrete switching where compact SMD footprint, low reverse leakage (<100 nA at 200 V), and thermal robustness (Tj = 150 °C) are critical.
Technical Context
The BAV23S integrates two independent silicon switching diodes in a single SOT23-3 package with shared terminal architecture: Pin 1 = A1, Pin 2 = K2, Pin 3 = K1/A2. This configuration supports series/anti-parallel or common-cathode/anode topologies without external interconnects.
Its 50 ns reverse recovery time is measured under standardized conditions (IF = IR = 10 mA, IR(meas) = 1 mA, RL = 100 Ω), and its 2 pF capacitance at 0 V / 1 MHz enables minimal signal distortion in RF-coupled or high-frequency gate-drive paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - supports repetitive blocking in 200 V DC bus applications with 25 % safety margin |
| trr | ≤50 ns - ensures minimal switching loss in 100–500 kHz SMPS designs |
| Cd | ≤2 pF at 0 V / 1 MHz - reduces capacitive loading on high-impedance control nodes |
| IR | ≤100 nA at VR = 200 V - maintains signal integrity in high-impedance voltage sensing |
| Ptot | 250 mW at Tamb ≤ 25 °C - defines maximum continuous power dissipation on standard FR4 PCB |
| Tj(max) | 150 °C - sets upper thermal limit for reliable operation in industrial ambient environments |
Pinout & Package
Package: SOT23 (TO-236AB), 3-terminal surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Forward current entry point for first diode; connects to high-side switch node in clamp circuits |
| 2 | Cathode of Diode 2 (K2) | Reverse-blocking terminal for second diode; used as output return in dual-rail clamping |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1, A2) | Shared terminal enabling compact dual-diode configurations-e.g., common-cathode rectifier or anti-parallel snubber |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 50 ns enables efficient operation up to 500 kHz in hard-switched topologies |
| Low junction capacitance | Cd ≤ 2 pF minimizes EMI generation and preserves rise/fall times in gate-drive isolation paths |
| High reverse voltage rating | VRRM = 250 V supports direct use across 200 V DC links without derating concerns |
| Thermal reliability | Rth(j-a) = 500 K/W on FR4 allows 250 mW dissipation with ΔT < 125 K above ambient |
Applications
| Switch-Mode Power Supply Snubber | High-Voltage Signal Clamping |
|---|---|
Use Scenario: Suppressing voltage spikes across MOSFET drains in flyback or forward converters operating at 100–300 kHz. IC Role / Device Role: Fast-recovery dual diode providing bidirectional clamping path with shared terminal reducing board space. Use Value: 50 ns trr and 250 V VRRM limit peak overshoot to <10 % above input rail while occupying one SOT23 footprint. |
Use Scenario: Protecting ADC inputs or op-amp rails from transient overvoltage in industrial sensor interfaces. IC Role / Device Role: Dual clamping diode limiting signal swing to ±0.7 V beyond supply rails using internal series resistance. Use Value: 2 pF capacitance avoids signal attenuation at 10 MHz bandwidth; 100 nA leakage preserves µA-level bias accuracy. |
| DC-DC Converter Output Rectification | Gate-Drive Level Shifting |
Use Scenario: Secondary-side synchronous rectification in isolated 48 V–200 V output DC-DC modules. IC Role / Device Role: Dual anode-cathode pair enabling complementary conduction paths for low-loss freewheeling. Use Value: Shared Pin 3 (K1/A2) simplifies PCB routing between transformer center-tap and synchronous FET gates. |
Use Scenario: Isolating and shifting logic-level PWM signals to high-side gate drivers in half-bridge motor controllers. IC Role / Device Role: Fast-switching diode pair providing level-shifted bootstrap charging and discharge paths. Use Value: 50 ns trr ensures clean edge transmission at 20–100 kHz PWM frequencies; SOT23 footprint fits tight gate-driver layouts. |
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 |
|---|---|---|---|
| BAV21,113 | VRRM = 200 V (lower), trr = 50 ns (same), SOT23 package | Not suitable for 200 V+ DC bus clamping; limited to ≤180 V systems | Select when cost sensitivity outweighs voltage margin and thermal headroom is constrained |
| MMBD2836LT1G | VRRM = 200 V, trr = 4 ns (faster), Cd = 1.5 pF (lower), same SOT23 | Better for >1 MHz gate drive but lacks 250 V rating; not validated for 200 V flyback snubbing | Prefer for ultra-high-frequency isolated gate drivers where voltage stress remains <160 V |
Compared with BAV21,113 and MMBD2836LT1G, the BAV23S uniquely balances 250 V blocking, 50 ns speed, and SOT23 integration-making it optimal for industrial 200 V DC-DC snubbers where voltage margin and layout density are co-constrained.

FAQ
What is the maximum continuous forward current per diode in the BAV23S?
The BAV23S supports 125 mA continuous forward current per diode when both diodes are simultaneously conducting (double diode loaded condition), as specified in Table 5. Derating applies above 25 °C ambient per Figure 5, with full rating maintained up to 85 °C on standard FR4 PCB.
Can the BAV23S be used in place of a single high-voltage diode?
Yes-the BAV23S can operate as a single diode by leaving either anode or cathode unconnected. Pin 1–3 forms Diode 1 (A1–K1), Pin 3–2 forms Diode 2 (A2–K2); unused terminals must be left floating or tied to safe potential per circuit requirements.
Is the BAV23S qualified for automotive applications?
No-the April 2023 data sheet explicitly states this part is non-automotive qualified. Automotive alternatives (e.g., BAV23S-Q) are available separately through Nexperia and require distinct qualification documentation and packaging.
How does the shared terminal (Pin 3) affect PCB layout in snubber designs?
Pin 3 (K1/A2) enables compact snubber layouts by eliminating external jumper traces-e.g., connecting transformer secondary center-tap directly to Pin 3, with Pins 1 and 2 routed to drain and ground respectively, reducing parasitic inductance by >30 % versus discrete dual-diode placement.
