Product details
Overview
BAV23CVL from Nexperia is a dual high-voltage switching diode in SOT23 package, configured as two anodes (A1, A2) sharing a common cathode (K1/K2), rated for 250 V repetitive peak reverse voltage (VRRM), 50 ns reverse recovery time (trr), and 2 pF junction capacitance - deployed in high-speed flyback snubbers and HV DC-DC converter clamp circuits.
For engineers reviewing the BAV23CVL datasheet, BAV23CVL pinout, BAV23CVL application, or BAV23CVL equivalent, key selection criteria include verified common-cathode dual-diode topology, sub-50 ns trr at IF = 10 mA/IR = 10 mA, 200 V DC blocking capability, low leakage (<100 nA at VR = 200 V), and thermal resistance of 500 K/W (junction-to-ambient, FR4 PCB).
Technical Context
This dual diode integrates two independent high-voltage PN junctions in a single SOT23 package with shared cathode terminal, enabling compact bidirectional clamping or dual-path switching without inter-device timing skew. Its 250 V VRRM rating supports operation in 200 V DC bus systems with margin, while the 50 ns trr ensures minimal switching loss in 100–500 kHz power topologies.
The device exhibits low 2 pF capacitance at 0 V bias and 1 MHz, reducing high-frequency coupling in gate-drive or signal-path applications; its 100 nA IR at 200 V and 25 °C enables stable performance in precision HV bias networks where leakage-induced offset must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - supports 200 V DC bus designs with 25 % voltage margin against transients |
| trr | 50 ns - enables efficient switching up to ~500 kHz in hard-switched converters |
| Cd | 2 pF - minimizes capacitive loading on fast edges in gate-clamp or signal routing |
| IR @ VR = 200 V | 100 nA - ensures negligible leakage current in high-impedance HV bias networks |
| IFRM | 625 mA - sustains pulsed forward current for transient surge suppression |
| Ptot | 250 mW - defines maximum continuous dissipation on standard FR4 PCB (single-sided copper) |
| Rth(j-a) | 500 K/W - quantifies thermal bottleneck for ambient-limited power handling at Tj ≤ 150 °C |
Pinout & Package
Encapsulated in SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, optimized for reflow soldering on FR4 PCBs with standard footprint per Figure 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Forward current entry point for first diode; connects to HV switch node in clamp configuration |
| 2 | Anode (Diode 2) | Independent forward current entry for second diode; enables dual-path or redundant clamping |
| 3 | Common Cathode (K1/K2) | Shared return path; simplifies PCB layout by eliminating separate cathode traces and reduces loop inductance |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 50 ns ensures minimal reverse recovery loss in 100–500 kHz SMPS designs |
| Low junction capacitance | Cd ≤ 2 pF reduces capacitive feedthrough in gate-drive snubber and signal isolation paths |
| Common-cathode dual-diode topology | Single-package integration eliminates inter-device timing mismatch and saves board space |
| High reverse voltage rating | VRRM = 250 V provides robustness against 200 V bus transients and line surges |
| Low leakage current | IR ≤ 100 nA at 200 V enables stable DC bias in high-Z sensing and reference circuits |
Applications
| Switch-Mode Power Supply Clamp | Flyback Converter Snubber |
|---|---|
Use Scenario: Clamping voltage spikes across MOSFET drains during turn-off in offline AC-DC adapters. IC Role / Device Role / Timing Role: Dual-anode common-cathode diode provides symmetrical clamping for dual-switch topologies or redundant protection paths. Use Value: 50 ns trr and 250 V VRRM prevent avalanche stress while minimizing energy loss in RCD snubbers. |
Use Scenario: Absorbing leakage inductance energy in isolated flyback transformers. IC Role / Device Role / Timing Role: Fast-recovery dual diode routes spike energy to clamp capacitor with minimal delay and overshoot. Use Value: 2 pF capacitance avoids high-frequency resonance; common cathode simplifies connection to shared clamp rail. |
| High-Voltage Signal Routing | DC Bus Voltage Monitoring |
Use Scenario: Level-shifting and protecting analog inputs exposed to ±150 V transient signals in industrial I/O modules. IC Role / Device Role / Timing Role: Dual diode clamps positive and negative excursions to safe rails using shared cathode reference. Use Value: 100 nA IR ensures <0.1 mV error in 1 MΩ input impedance monitoring circuits at 200 V bias. |
Use Scenario: Dividing and conditioning 200 V DC bus voltage for ADC input in battery management systems. IC Role / Device Role / Timing Role: Acts as precision HV clamp on resistor divider output to protect downstream op-amps. Use Value: Low 2 pF capacitance prevents phase shift in 100 kHz bandwidth monitoring loops. |
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 NSR20F25HT1G | VRRM = 250 V, trr = 35 ns, Cd = 3.5 pF, SOD-123FL package (larger, 2-terminal per diode) | Requires separate cathode routing; higher capacitance increases HF feedthrough risk | Preferred when lower trr is critical and board area allows larger discrete placement |
| Diodes Inc. BAV23S | VRRM = 200 V, trr = 50 ns, Cd = 2 pF, identical SOT23 pinout but single-anode dual-cathode configuration | Not pin-compatible: cathodes are isolated, requiring redesign of common-rail connections | Select only if system voltage stays ≤180 V and layout permits split cathode routing |
Compared with NSR20F25HT1G and BAV23S, BAV23CVL uniquely delivers common-cathode integration in SOT23 with matched 250 V/50 ns/2 pF specs - enabling compact, low-inductance clamp layouts unachievable with discrete or alternate-pinout alternatives.

FAQ
What is the maximum continuous forward current per diode for BAV23CVL?
The BAV23CVL supports 125 mA continuous forward current per diode under double-diode loaded conditions at Tamb ≤ 25 °C on FR4 PCB. Derating applies above 25 °C per Figure 5: at 85 °C ambient, max IF drops to ~70 mA per diode due to thermal limits.
Is BAV23CVL automotive-qualified?
No. BAV23CVL is explicitly marked as non-automotive qualified per Nexperia's revision history (v.8, April 2023). It lacks AEC-Q101 qualification and is not tested to automotive temperature or reliability standards. For automotive use, consult Nexperia's BAV23C-Q series.
How does the common-cathode configuration affect PCB layout?
The shared cathode (Pin 3) eliminates need for separate cathode traces, reducing loop area and parasitic inductance in clamp circuits. Layout requires only one cathode net tied to ground or clamp rail, simplifying routing and improving EMI performance versus dual-isolated diodes.
Can BAV23CVL replace BAV23S in existing designs?
No - BAV23S uses isolated cathodes (Pin 3 = K1, Pin 1 = K2), while BAV23CVL uses common cathode (Pin 3 = K1/K2). Direct substitution would short the cathodes and disrupt circuit function. Board-level redesign is required to accommodate the different pinout and topology.
