Product details
Overview
D5V0F1B2WS from Diodes Incorporated is a bidirectional ultra-low-capacitance TVS diode designed for ESD protection of high-speed data lines. It features a 5 V reverse working voltage, 6 V minimum breakdown voltage, 2 pF typical junction capacitance, ±25 kV IEC 61000-4-2 contact/air ESD rating, and 17 A peak pulse current-enabling robust protection in USB 2.0, Ethernet PHY, and audio jack interfaces without signal integrity degradation.
For engineers reviewing the D5V0F1B2WS datasheet, D5V0F1B2WS pinout, D5V0F1B2WS application, or D5V0F1B2WS equivalent, key selection criteria include sub-3 pF capacitance for >480 Mbps data rates, bidirectional clamping for AC-coupled lines, SOD323 footprint compatibility with space-constrained PCBs, and automotive-grade availability via Diodes' AEC-Q200-qualified variants.
Technical Context
This device operates as a single-channel, bidirectional transient voltage suppressor optimized for electrostatic discharge suppression on unidirectional or differential data paths. Its low 2 pF capacitance minimizes signal distortion at frequencies up to 1 GHz, while the 6 V–8 V breakdown range ensures reliable conduction before IC-level damage occurs under ESD stress.
The SOD323 package supports high-density routing with thermal resistance of 500 °C/W and a 250 mW steady-state power dissipation limit. Clamping voltage remains ≤9.8 V at 1 A and ≤15 V at 17 A (8/20 μs), providing predictable overvoltage limiting during fast transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5 V - Maximum continuous DC or RMS signal voltage the line can carry without leakage-induced errors |
| Breakdown Voltage (VBR) | 6 V min - Ensures conduction initiates before downstream ICs (e.g., USB PHY) reach absolute maximum ratings |
| Junction Capacitance (CT) | 2 pF typ - Enables use in USB 2.0 (480 Mbps), 100BASE-TX, and I²S audio without measurable rise-time degradation |
| ESD Rating | ±25 kV air/contact - Meets IEC 61000-4-2 Level 4, eliminating need for secondary board-level ESD mitigation |
| Peak Pulse Current (IPP) | 17 A (8/20 μs) - Sustains full-rated surge without parametric shift or bond-wire failure |
| Clamping Voltage (VCL) | 15 V max at 17 A - Limits transient excursion to safe levels for 3.3 V or 5 V interface ICs |
Pinout & Package
Package: SOD323 - 2-pin surface-mount plastic package with 0.3 mm lead width, 1.3 mm body width, and 2.5 mm body length; compatible with standard reflow profiles (260 °C, 10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | ESD current sink for positive transients | Connected to protected line; conducts when voltage exceeds +6 V relative to cathode |
| Cathode (Pin 2) | ESD current sink for negative transients | Connected to protected line; conducts when voltage falls below –6 V relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD clamping | Enables protection of AC-coupled or floating data lines (e.g., USB D+/D–, Ethernet pairs) without polarity constraints |
| 2 pF typical capacitance | Preserves signal integrity in high-speed interfaces up to 480 Mbps with <0.5% rise-time degradation |
| ±25 kV IEC 61000-4-2 rating | Eliminates need for external spark gaps or multi-stage protection in handheld and industrial end-equipment |
| SOD323 footprint | Reduces PCB area by 60% vs. SOT-23 while maintaining solder joint reliability per J-STD-020 Level 1 moisture sensitivity |
Applications
| USB 2.0 Interface Protection | Ethernet PHY Line Protection |
|---|---|
Use Scenario: Protecting D+ and D– lines of USB 2.0 host/device ports against user-handling ESD events. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed directly at connector, shunting ESD energy to ground before reaching USB transceiver. Use Value: 2 pF capacitance avoids eye-diagram closure; ±25 kV rating prevents latch-up or gate oxide rupture in PHY ICs. | Use Scenario: Shielding 100BASE-TX twisted-pair receive lines from ESD induced on RJ-45 connectors. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted at PCB edge, clamping common-mode surges without distorting 100 MHz differential signaling. Use Value: Sub-3 pF loading maintains return loss >15 dB up to 100 MHz; 15 V clamping protects PHY's 3.3 V receiver inputs. |
| Smartphone Audio Jack ESD | Industrial Sensor Interface |
Use Scenario: Guarding 3.5 mm TRRS audio jacks against repeated plug-in/out ESD in consumer handsets. IC Role / Device Role / Timing Role: Single-channel bidirectional TVS across left/right/ground paths, absorbing contact discharges before codec inputs. Use Value: 5 V VRWM allows direct placement on biased analog audio lines; 2 pF prevents audible pop/noise artifacts. | Use Scenario: Safeguarding RS-485 or CAN FD transceiver I/O pins in factory automation nodes exposed to maintenance personnel ESD. IC Role / Device Role / Timing Role: Point-of-entry TVS on differential bus lines, limiting transients to <15 V during ±25 kV contact events. Use Value: SOD323 size fits tight connector zones; 17 A IPP handles multiple ESD strikes without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-01UTG | 0.3 pF lower CT (1.7 pF typ), same 5 V VRWM and ±25 kV rating; 10% higher VBR (6.5 V min) | Better suited for >1 Gbps interfaces (e.g., USB 3.2 Gen 1); slightly higher clamping threshold | Select when minimizing capacitance is critical and system margin allows 0.5 V higher trigger voltage |
| SZ1.5SMC5.0A | Unidirectional, 5.0 V VRWM, 100 pF CT, 100 A IPP - larger package (DO-214AB), higher power handling | Applicable only to DC-biased lines; unsuitable for AC-coupled or high-speed data due to capacitance | Choose only for low-frequency power rail or legacy serial port protection where speed is not constrained |
Compared with SP1003-01UTG, D5V0F1B2WS offers tighter VBR tolerance and broader automotive qualification path; versus SZ1.5SMC5.0A, it enables high-speed data integrity but trades off surge energy capacity for miniaturization.

FAQ
What is the maximum operating temperature for D5V0F1B2WS?
The D5V0F1B2WS is rated for continuous operation from –55 °C to +125 °C junction temperature. This range supports deployment in automotive cabin modules, industrial controllers, and outdoor-connected devices without derating under normal PCB thermal conditions.
Can D5V0F1B2WS be used on 3.3 V logic lines?
Yes-its 5 V reverse working voltage and 6 V minimum breakdown ensure safe operation on 3.3 V systems. The 9.8 V clamping voltage at 1 A limits transient overshoot well below the 4.6 V absolute maximum for most 3.3 V I/O cells, preventing latch-up or oxide damage.
Is D5V0F1B2WS compliant with RoHS and halogen-free standards?
Yes-D5V0F1B2WS is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen-antimony free ("Green" per Diodes' definition: <900 ppm Br, <900 ppm Cl, <1000 ppm Sb). Certificate of Compliance is available upon request.
Does this device require external biasing or series impedance?
No-D5V0F1B2WS is a passive, two-terminal device that requires no external components. It connects directly across the protected line and ground (or between differential pair conductors), with no bias voltage, current-limiting resistors, or RC networks needed for basic ESD protection.
