Product details
Overview
BAV23C-7-F from Diodes Incorporated is a surface-mount high-voltage dual switching diode in SOT23 package, featuring 250 V repetitive peak reverse voltage (VRRM), 50 ns reverse recovery time (tRR), and 400 mA forward current (IF). It integrates two independent silicon switching diodes in a single compact footprint, optimized for DC-DC converter flyback snubbing and battery protection circuits in portable electronics.
For engineers reviewing the BAV23C-7-F datasheet, BAV23C-7-F pinout, BAV23C-7-F application, or BAV23C-7-F equivalent, key selection criteria include reverse breakdown voltage stability at +150°C, low leakage (<100 nA @ 200 V, 25°C), fast recovery performance under 30 mA switching conditions, and JEDEC-qualified reliability for industrial-grade power management designs.
Technical Context
This dual diode operates with independent anode-cathode paths sharing a common cathode configuration (BAV23C variant), enabling synchronous clamping and bidirectional transient suppression in compact DC-DC topologies. Its 357°C/W junction-to-ambient thermal resistance supports operation up to +150°C ambient when mounted on standard FR-4 PCBs.
The device delivers consistent 1.0 V forward voltage at 100 mA and maintains <5.0 pF total capacitance at 0 V bias-critical for minimizing switching losses and EMI in high-frequency (>1 MHz) power conversion stages where parasitic capacitance directly impacts efficiency and noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - Enables use in 200 V DC bus systems with 25% safety margin against voltage transients |
| tRR | 50 ns - Supports switching frequencies up to ~2 MHz without excessive recovery loss |
| IF | 400 mA - Sustains continuous conduction in low-power auxiliary rails and signal-level clamping |
| IR | <100 nA @ 200 V, 25°C - Minimizes standby power drain in battery-backed circuits |
| CT | <5.0 pF @ 0 V - Reduces capacitive coupling and ringing in high-dv/dt gate-drive or feedback paths |
| PD | 350 mW - Limits self-heating to <125°C junction rise above 25°C ambient on standard PCB layout |
Pinout & Package
Package: SOT23 - 3-pin surface-mount plastic package (2.4 mm × 1.3 mm × 1.0 mm), UL 94V-0 rated, moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.

|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first diode path; connects to switching node in clamp or freewheeling applications |
| Pin 2 | Cathode (Common) | Shared cathode terminal for both diodes; ties to ground or positive rail depending on topology |
| Pin 3 | Anode of Diode 2 | Independent input node for second diode; enables dual-path routing without external interconnect |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-qualified reliability | Qualified per AEC-Q standards for high-reliability industrial and automotive-adjacent applications |
| Low leakage current | <100 nA @ 200 V, 25°C ensures minimal battery discharge in always-on portable subsystems |
| Fast reverse recovery | 50 ns tRR enables efficient operation in 500 kHz–2 MHz DC-DC converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV23A-7-F | Same package and VRRM, but common-anode configuration instead of common-cathode | Requires inverted PCB layout; suited for positive-rail clamping rather than ground-referenced snubbing | Select when cathode must tie to system ground and anodes connect to switched nodes |
| MMBD23C-7-F | Identical pinout and electrical specs, but manufactured by ON Semiconductor with different process qualification | No functional difference; qualified to same JEDEC standards but with separate AEC-Q documentation | Choose for multi-source procurement or legacy design continuity with ON Semi platforms |
Compared with BAV23A-7-F and MMBD23C-7-F, the BAV23C-7-F provides unique common-cathode topology for ground-referenced clamping, while maintaining identical voltage, speed, and thermal specs-making it irreplaceable in layouts requiring shared cathode routing without trace rework.

FAQ
What is the pin configuration of BAV23C-7-F?
BAV23C-7-F uses a common-cathode configuration in SOT23: Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. This layout enables dual-path clamping with a single ground reference point, confirmed by Diodes' DS30042 Rev. 23 top-view diagram and marking code KT6.
Does BAV23C-7-F support automotive applications?
BAV23C-7-F itself is not automotive-qualified, but its automotive-compliant counterpart BAV23CQ-7-F is available under a separate datasheet (DS30042-AQ). The base part meets JEDEC high-reliability standards and is widely used in industrial and medical equipment where AEC-Q200 is not mandated.
How does thermal derating affect BAV23C-7-F's power handling?
Per Figure 1 in DS30042 Rev. 23, BAV23C-7-F's 350 mW maximum power dissipation linearly derates above +25°C ambient at 2.8 mW/°C. At +100°C ambient, usable power drops to ~140 mW-requiring careful layout with thermal vias if operating near IF = 400 mA continuously.
Can BAV23C-7-F replace BAV23S-7-F in existing designs?
No-BAV23S-7-F has a series-connected dual-diode configuration (anode-to-cathode-to-anode), whereas BAV23C-7-F is common-cathode. Swapping them would invert circuit functionality and likely cause open-circuit or short-circuit behavior; pin compatibility does not imply functional equivalence.
