Product details
Overview
BAV23C-HE3_A-18 from Vishay Semiconductors is a dual silicon epitaxial planar switching diode with common cathode configuration, rated for 200 V continuous reverse voltage, 50 ns reverse recovery time, and 400 mA forward current. It is AEC-Q101 qualified and packaged in SOT-23 for automotive power supply clamping and signal routing applications.
For engineers reviewing the BAV23C-HE3_A-18 datasheet, BAV23C-HE3_A-18 pinout, BAV23C-HE3_A-18 application, or BAV23C-HE3_A-18 equivalent, key selection criteria include its fast recovery (50 ns), low dynamic resistance (5 Ω), 5 pF junction capacitance at 0 V, AEC-Q101 qualification status, and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BAV23C-HE3_A-18 integrates two independent fast-switching diodes sharing a common cathode terminal, enabling compact dual-path rectification or polarity protection in single-package form. Its epitaxial planar construction ensures stable reverse breakdown (250 V min) and low leakage (100 nA at 200 V, 25 °C).
Designed for high-speed operation, it delivers 50 ns reverse recovery time under IF = IR = 30 mA conditions and maintains thermal stability up to 150 °C junction temperature, supported by MSL 1 moisture sensitivity and UL 94 V-0 molding compound.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual fast-switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV23S-HE3_A-18 | Single-diode variant in same SOT-23 package; identical electrical specs except dual vs. single configuration | Used where only one clamping path is required; no common-cathode functionality | Select BAV23S-HE3_A-18 when circuit design uses discrete single-diode placement instead of dual-path integration |
| MMBD231C-7-F | Non-AEC-Q101 commercial-grade dual diode; same VR, trr, and VF but lacks automotive qualification and MSL 1 rating | Suitable for industrial or consumer applications without automotive reliability requirements | Choose MMBD231C-7-F for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with BAV23C-HE3_A-18, BAV23S-HE3_A-18 offers identical performance in a single-diode form factor-ideal for redesigns eliminating redundancy-while MMBD231C-7-F provides equivalent speed and voltage ratings at lower cost for non-automotive use, though without AEC-Q101 validation or enhanced thermal robustness.

FAQ
What is the AEC-Q101 qualification status of the BAV23C-HE3_A-18?
The BAV23C-HE3_A-18 is explicitly AEC-Q101 qualified per the Vishay datasheet Rev. 1.1 (21-Feb-2024), confirming compliance with stress tests including temperature cycling, high-temperature reverse bias, and ESD. This qualification validates its suitability for automotive under-hood applications where reliability at -55 °C to +150 °C is mandatory. The "HE3_A" suffix denotes this certified grade.
Does the BAV23C-HE3_A-18 have a common anode or common cathode configuration?
The BAV23C-HE3_A-18 uses a common cathode configuration, with Pin 2 serving as the shared cathode terminal and Pins 1 and 3 as independent anodes. This arrangement is confirmed in the Vishay datasheet's "Circuit Configuration" column and mechanical drawings, enabling dual-path clamping or OR-ing functions without external node tying.
What is the maximum forward current rating for continuous operation of the BAV23C-HE3_A-18?
The BAV23C-HE3_A-18 supports a maximum average forward rectified current (IF(AV)) of 200 mA at f ≥ 50 Hz and a forward continuous current (IF) of 400 mA under DC conditions. These values are specified in the Absolute Maximum Ratings table and assume operation on an FR-4 board with Vishay's recommended soldering footprint.
How does the reverse recovery time of the BAV23C-HE3_A-18 impact high-frequency circuit performance?
The BAV23C-HE3_A-18 has a reverse recovery time (trr) of 50 ns under IF = IR = 30 mA, RL = 100 Ω test conditions. This enables clean switching in PWM frequencies up to ~2 MHz before significant tail current causes efficiency loss or EMI. In practice, it supports stable operation in 500 kHz–1 MHz DC-DC converters and digital signal clamping without oscillation or shoot-through risk.
Is the BAV23C-HE3_A-18 compatible with lead-free reflow processes?
Yes, the BAV23C-HE3_A-18 is compatible with lead-free reflow soldering, with a peak temperature rating of 260 °C per J-STD-020. Its MSL 1 rating means unlimited floor life at ≤30 °C/60% RH, and the UL 94 V-0 molding compound ensures thermal stability during standard Pb-free profile ramp-soak-reflow cycles.
