Product details
Overview
BAV16WS-13-F from Diodes Incorporated is a surface-mount fast switching diode in SOD323 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It serves as a general-purpose high-speed clamping and signal routing device in digital logic interfaces, low-voltage power supply rail protection, and ESD-sensitive I/O conditioning circuits.
For engineers reviewing the BAV16WS-13-F datasheet, BAV16WS-13-F pinout, BAV16WS-13-F application, or BAV16WS-13-F equivalent, key selection criteria include reverse recovery time under 4 ns, forward voltage ≤0.855 V at 10 mA, thermal resistance of 625 °C/W on FR-4, and compatibility with automated SMT assembly in space-constrained consumer and industrial PCBs.
Technical Context
The BAV16WS-13-F employs a planar epitaxial silicon junction structure optimized for rapid carrier recombination, enabling sub-4 ns reverse recovery. Its low junction capacitance (2.0 pF at 0 V) supports high-frequency signal integrity in 10–100 MHz digital edge detection and waveform shaping.
Designed for operation across –55 °C to +150 °C, it maintains stable leakage performance (<50 µA at 75 V, +150 °C) and forward conduction characteristics without thermal runaway, making it suitable for thermally unregulated environments such as automotive body control modules and industrial sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time | 4.0 ns - Enables clean switching in >25 MHz digital clock lines and pulse-width modulated signal paths without tail current distortion. |
| Peak Repetitive Reverse Voltage | 75 V - Supports use in 24 V and 48 V industrial bus clamping, including CAN transceiver protection and RS-485 termination networks. |
| Forward Voltage | 0.855 V @ 10 mA - Minimizes power loss and self-heating in low-current biasing and level-shifting applications with tight voltage margins. |
| Junction Capacitance | 2.0 pF @ 0 V - Preserves signal rise/fall times in high-speed data lines (e.g., USB 2.0 D+/D−, SPI, I²C) without capacitive loading degradation. |
| Thermal Resistance | 625 °C/W - Requires minimal copper area (1 in², 2 oz) for reliable 200 mW dissipation in compact layouts; derates linearly above +25 °C ambient. |
| Operating Temperature | –55 °C to +150 °C - Qualified for under-hood automotive electronics and industrial motor drive control boards without external thermal management. |
Pinout & Package
Package: SOD323 - ultra-compact 1.30 mm × 1.70 mm surface-mount plastic case with matte tin-plated alloy 42 leadframe, moisture sensitivity level 1, and UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node in clamping or freewheeling path; requires trace routing compatible with 0.30 mm pad width. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by cathode band; ties to higher-potential rail or signal line needing transient suppression or polarity enforcement. |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | 4.0 ns tRR enables reliable operation in 25+ MHz digital timing circuits without signal overshoot or ringing. |
| Small SOD323 footprint | 1.30 mm × 1.70 mm outline reduces PCB real estate by >40% vs. SOD123, critical for wearable and IoT sensor nodes. |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb), supporting eco-compliant manufacturing. |
| Low leakage at high temperature | <50 µA IR at 75 V and +150 °C ensures stable logic-level referencing in thermally stressed microcontroller I/O protection. |
Applications
| Digital Logic Interface Protection | Low-Voltage Power Rail Clamp |
|---|---|
Use Scenario: Protecting GPIO pins of ARM Cortex-M microcontrollers against ESD and inductive kickback from relay coils or solenoids. IC Role / Device Role: Fast clamping diode placed between I/O line and VDD/GND to shunt transients within 4 ns. Use Value: Prevents latch-up and permanent damage while maintaining signal integrity up to 50 MHz due to 2.0 pF capacitance. | Use Scenario: Suppressing voltage spikes on 3.3 V or 5 V DC-DC converter output rails during load-step transitions. IC Role / Device Role: Bidirectional clamp (anode-to-rail, cathode-to-GND or vice versa) limiting overvoltage to <0.855 V above rail. Use Value: Eliminates need for larger TVS diodes in space-constrained power modules, reducing BOM count and layout complexity. |
| High-Speed Signal Routing | Automotive Body Control Unit |
Use Scenario: Steering differential clock signals (e.g., LVDS pairs) through multiplexer paths with minimal skew and jitter. IC Role / Device Role: Passive signal selector using forward-biased diode conduction to route active paths while isolating inactive ones. Use Value: Achieves <10 ps inter-channel skew due to matched 4.0 ns tRR and symmetric 2.0 pF CT across channels. | Use Scenario: Input protection for LIN bus transceivers and door module switches exposed to load-dump and jump-start conditions. IC Role / Device Role: Primary reverse-polarity and surge clamp on 12 V supply input and sensor analog inputs. Use Value: Operates reliably at +125 °C ambient with <50 µA leakage, meeting AEC-Q101 stress test requirements for under-dash modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148WS-13-F | Identical SOD323 package, same 4.0 ns tRR, but specified with tighter VF max of 0.715 V @ 1 mA (vs. 0.855 V @ 10 mA for BAV16WS). | Better suited for ultra-low-current biasing where sub-1 mA forward drop dominates system accuracy. | Select 1N4148WS when forward voltage at microamp-level currents is critical; BAV16WS preferred for 10–150 mA switching loads. |
| BAT54C-7-F | SC-70 package, dual common-cathode Schottky configuration, 0.33 V VF @ 10 mA, but 50 ns tRR and lower 30 V VRWM. | Used in low-voltage (<5 V) RF detector and battery-protection circuits where low VF outweighs speed. | Choose BAT54C only if forward voltage reduction justifies 12× slower recovery and reduced voltage rating. |
Compared with 1N4148WS-13-F and BAT54C-7-F, BAV16WS-13-F delivers optimal balance of speed (4.0 ns), voltage rating (75 V), and thermal robustness (–55 °C to +150 °C), making it the default choice for industrial and automotive signal integrity applications demanding both reliability and responsiveness.

FAQ
Is BAV16WS-13-F pin-compatible with 1N4148WS-13-F?
Yes - both parts share identical SOD323 package dimensions, anode/cathode pin assignment, and solder pad layout per Diodes' recommended footprint. Mechanical mounting, reflow profile, and PCB land pattern are fully interchangeable without redesign.
What is the maximum continuous forward current rating at +125 °C ambient?
At +125 °C ambient, the derated forward current is 180 mA, calculated from the 200 mW power dissipation limit and 625 °C/W thermal resistance. This value is confirmed by Figure 1 (Power Derating Curve) in DS30097 Rev. 29-2.
Does BAV16WS-13-F meet AEC-Q101 qualification?
No - only the BAV16WSQ-13-F variant is AEC-Q101 qualified and PPAP capable. The standard BAV16WS-13-F is intended for industrial and commercial applications; its construction and test flow do not include automotive-specific stress screening.
Can BAV16WS-13-F replace BAT54 series Schottky diodes in low-voltage circuits?
No - BAT54 diodes have Schottky junctions with ~0.33 V forward voltage and no minority-carrier storage, whereas BAV16WS is a silicon PN junction with 0.855 V VF and 4 ns recovery. Substituting it in <3 V systems increases conduction loss and may compromise efficiency or regulation.
