Product details
Overview
BAV23C-Q from Nexperia is a dual high-voltage switching diode in SOT23 package, configured as two anodes sharing a common cathode. It delivers 250 V repetitive peak reverse voltage (VRRM), ≤50 ns reverse recovery time (trr), and ≤2 pF junction capacitance - enabling fast, low-loss switching in automotive power supplies and HV DC-DC converters.
For engineers reviewing the BAV23C-Q datasheet, BAV23C-Q pinout, BAV23C-Q application, or BAV23C-Q equivalent, key selection criteria include its AEC-Q101 qualification, common-cathode dual-diode topology, 200 V DC reverse blocking capability, and thermal resistance of 500 K/W (junction-to-ambient) on FR4 PCB.
Technical Context
The BAV23C-Q integrates two independent silicon switching diodes in a single SOT23 package with shared cathode (Pin 3), supporting parallel or independent high-voltage switching paths. Its design targets transient suppression and flyback energy management where low trr and minimal Cd reduce switching losses.
It operates across −65 °C to +150 °C ambient, with 125 mA continuous forward current per diode and 250 mW total power dissipation at Tamb ≤ 25 °C. The device meets AEC-Q101 stress test requirements for automotive underhood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - supports repetitive reverse voltage up to 250 V without breakdown, suitable for 200 V DC bus clamping |
| trr | ≤50 ns - enables switching frequencies above 1 MHz in SMPS and snubber circuits |
| Cd | ≤2 pF at VR = 0 V, f = 1 MHz - minimizes capacitive loading in high-speed signal routing |
| IR | ≤100 nA at VR = 200 V - ensures low leakage in high-impedance bias networks |
| IF | 125 mA per diode - supports moderate-current flyback diode operation in auxiliary rails |
| Rth(j-a) | 500 K/W - defines thermal derating slope: 0.5 mW/°C above 25 °C ambient on standard FR4 |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, qualified per AEC-Q101.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode path; connects to HV switch drain or inductive load |
| 2 | Anode (Diode 2) | Independent input node for second diode path; enables dual-rail or redundancy use |
| 3 | Common Cathode | Shared output node tied to ground or return rail; simplifies PCB layout for dual-diode configuration |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood use including temperature cycling, HTRB, and ESD testing |
| Common-cathode dual-diode topology | Reduces footprint vs. two discrete SOT23 diodes; eliminates cathode trace routing mismatch |
| Low trr (≤50 ns) | Minimizes reverse recovery loss in 100–500 kHz flyback and boost converters |
| Low Cd (≤2 pF) | Preserves signal integrity in HV gate-drive bootstrap paths and timing circuits |
Applications
| Automotive HVAC Power Supply | Industrial PLC Input Protection |
|---|---|
|
Use Scenario: Clamping inductive kickback from blower motor drivers in 24 V HVAC modules. IC Role / Device Role / Timing Role: Dual-anode configuration allows separate protection for two motor phases sharing one cathode return. Use Value: 250 V VRRM withstands load-dump transients; ≤50 ns trr prevents cross-conduction during PWM commutation. |
Use Scenario: Reverse-polarity and surge protection on 24 V digital input channels of modular PLCs. IC Role / Device Role / Timing Role: Acts as bidirectional clamp pair - each anode protects one signal line, common cathode ties to 24 V rail. Use Value: ≤100 nA IR at 200 V ensures negligible leakage in high-impedance optocoupler bias networks. |
| DC-DC Converter Flyback Diode | High-Voltage Sensor Bias Network |
|
Use Scenario: Secondary-side rectification in isolated 48 V → 5 V flyback converters for ADAS domain controllers. IC Role / Device Role / Timing Role: Dual diode provides redundancy or split-current path to reduce thermal stress per junction. Use Value: 125 mA IF rating supports 100 mA average output with margin; 500 K/W Rth(j-a) enables 75 °C max ambient operation. |
Use Scenario: Voltage divider stabilization and transient suppression in 200 V battery monitoring sensors. IC Role / Device Role / Timing Role: One diode clamps positive overvoltage; the other provides reverse-bias leakage control on reference leg. Use Value: ≤2 pF Cd avoids phase shift in 100 kHz sampling clocks; AEC-Q101 ensures reliability in EV battery packs. |
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 MMBD233L | VRRM = 200 V (vs. 250 V); trr = 50 ns; same SOT23 common-cathode pinout | Lacks AEC-Q101 qualification; rated only for industrial temp range (−55 °C to +150 °C) | Select when automotive qualification is not required and 200 V blocking suffices |
| Diodes Incorporated BAV23S | VRRM = 250 V; trr = 50 ns; but uses isolated cathodes (3-pin SOT23 with separate K1/K2) | Requires additional PCB routing; no shared-cathode advantage for compact layouts | Choose only if independent cathode control is needed for asymmetric circuit topologies |
Compared with MMBD233L and BAV23S, the BAV23C-Q uniquely combines AEC-Q101 qualification, 250 V VRRM, and true common-cathode integration - delivering space savings and automotive compliance where dual-path clamping or redundancy is critical.

FAQ
Is BAV23C-Q pin-compatible with standard SOT23 dual-diode packages?
Yes - BAV23C-Q uses standard SOT23 (TO-236AB) footprint with 1.9 mm pin pitch and identical mechanical dimensions. Pin 1 = A1, Pin 2 = A2, Pin 3 = common cathode (K1/K2), matching JEDEC MO-203AA outline and IPC-7351B land pattern SOT23_190.
What is the maximum continuous forward current per diode at 100 °C ambient?
At Tamb = 100 °C, the derated forward current is 62.5 mA per diode, calculated from the 125 mA rating at 25 °C and linear derating slope of 0.5 mW/°C (based on Rth(j-a) = 500 K/W and Ptot = 250 mW).
Does BAV23C-Q support wave soldering?
Yes - Nexperia provides dedicated wave soldering footprint (Fig. 9) with 1.4 mm pad width, 2.2 mm length, and 2.6 mm spacing. Recommended preheat: 100–120 °C; peak temperature: 260 °C for ≤5 s; conveyor speed: 0.8–1.2 m/min.
How does the common-cathode configuration affect thermal performance?
Thermal resistance remains 500 K/W (junction-to-ambient) because both diodes share the same die substrate and thermal path through the common cathode bond wire and leadframe. Power dissipation must be summed across both diodes (max 250 mW total) for thermal design.
