Product details
Overview
D5V0L2B3W-7 from Diodes Incorporated is a 2-channel, bidirectional TVS diode array designed for ESD protection of high-speed data lines in portable electronics. It features 5.0 V reverse working voltage, ≤20 pF channel capacitance, ±30 kV IEC 61000-4-2 contact/air ESD rating, and 84 W peak pulse power dissipation - deployed in cellular handset USB/UART interfaces to suppress transient surges without signal integrity degradation.
For engineers reviewing the D5V0L2B3W-7 datasheet, D5V0L2B3W-7 pinout, D5V0L2B3W-7 application, or D5V0L2B3W-7 equivalent, key selection criteria include low-capacitance ESD clamping for >100 Mbps serial links, SOT323 package compatibility with space-constrained PCB layouts, thermal derating behavior at +85°C ambient, and differential resistance under 0.2 Ω during 6 A transients.
Technical Context
This bi-directional TVS array uses silicon avalanche junctions optimized for fast response (<1 ns) to electrostatic discharge events while maintaining low dynamic impedance across its operating voltage range. Each channel operates symmetrically between pins 1–3 and 2–3, sharing a common cathode (Pin 3), enabling dual-line protection without polarity constraints.
The device's 15–20 pF input capacitance at 1 MHz and 0 V bias ensures minimal loading on high-frequency signal paths such as USB 2.0, HDMI DDC, or MIPI D-PHY lanes. Its clamping voltage remains ≤14.0 V at 6 A (8/20 μs), limiting downstream IC stress during surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5.0 V - Maximum continuous DC voltage before leakage exceeds 100 nA; sets upper limit for protected signal swing. |
| Breakdown Voltage | 6–8 V @ 1 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage. |
| Clamping Voltage | 11.5–14.0 V @ 5–6 A - Peak voltage seen by protected IC during worst-case 8/20 μs surge; defines maximum stress level. |
| Channel Capacitance | 15–20 pF @ 0 V, 1 MHz - Measured pin-to-common-cathode; enables <1% signal distortion on 480 Mbps USB 2.0 lines. |
| ESD Rating | ±30 kV air/contact - Complies with IEC 61000-4-2 Level 4; qualifies for front-panel button, SIM card, and micro-USB port protection. |
| Peak Pulse Power | 84 W @ 8/20 μs - Sustained energy absorption capability per channel; supports multiple surge events without degradation. |
| Differential Resistance | ≤0.2 Ω @ 1 A - Low dynamic impedance during conduction; minimizes voltage overshoot during fast-rising transients. |
Pinout & Package
Package: SOT323 - 3-pin surface-mount plastic package (2.10 × 1.30 × 0.90 mm), RoHS-compliant, moisture sensitivity level 1, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Protected line input (e.g., USB D+); conducts to common cathode during positive or negative overvoltage. |
| Pin 2 | Anode of Channel 2 | Second protected line input (e.g., USB D−); symmetrical bidirectional clamping path with Pin 1. |
| Pin 3 | Common Cathode | Shared return node tied to system ground; establishes reference for both channels' avalanche breakdown. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Two independent symmetrical clamping paths (Pin1–Pin3 and Pin2–Pin3) eliminate need for polarity-aware layout. |
| Low Input Capacitance | 15–20 pF per channel enables use on 480 Mbps USB 2.0, 100 Mbps Ethernet PHY, and MIPI C-PHY v1.0 interfaces. |
| High ESD Withstand | ±30 kV contact/air per IEC 61000-4-2 ensures robustness against human-body-model discharges in handheld devices. |
| SOT323 Footprint | Compatible with standard 0805-sized land patterns; allows drop-in replacement in existing compact PCB designs. |
| Lead-Free & Green | Meets RoHS 2 and halogen-free requirements; matte tin plating ensures solderability per MIL-STD-202 Method 208. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional low-capacitance TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Unidirectional, higher capacitance (≈40 pF), DO-214AC package (larger footprint) | Requires separate anode/cathode routing; unsuitable for differential high-speed lines | Select only if board space permits larger package and signal polarity is fixed. |
| SP1001-01WTG | Single-channel, 0.3 pF capacitance, SOD-323 package, lower power rating (30 W) | Needs two devices for dual-line protection; better for >5 Gbps SerDes but less robust for 6 A surges | Prefer when protecting PCIe Gen4 or USB 3.2 Gen2x2 lanes where sub-0.5 pF is mandatory. |
Compared with SMAJ5.0A and SP1001-01WTG, D5V0L2B3W-7 uniquely balances dual-channel integration, 15–20 pF capacitance, ±30 kV ESD rating, and SOT323 size - making it optimal for cost-sensitive, space-constrained USB/MIPI interfaces requiring proven 6 A surge resilience.

FAQ
What is the maximum clamping voltage at 3 A for D5V0L2B3W-7?
The clamping voltage is specified as 8.7–10.7 V at 3 A (8/20 μs pulse), measured from Pin 1 to Pin 3 or Pin 2 to Pin 3. This value reflects the peak voltage imposed on protected circuitry during a mid-level ESD event and is validated per Figure 1 waveform in DS35567 Rev. 4-2.
Can D5V0L2B3W-7 be used for unidirectional signal lines?
Yes - although inherently bidirectional, it functions reliably on unidirectional lines (e.g., UART TX/RX) by clamping both positive and negative excursions relative to the common cathode (Pin 3). No polarity reversal or external biasing is required, simplifying layout versus unidirectional TVS arrays.
Is the SOT323 package lead-free and RoHS compliant?
Yes - the SOT323 package uses matte tin finish over Alloy 42 leadframe, fully compliant with EU RoHS Directive 2011/65/EU and Diodes' "Green" policy. It contains no intentionally added lead, halogens, or antimony, and meets UL 94V-0 flammability rating.
How does channel capacitance vary with reverse bias voltage?
Per Figure 3 in DS35567, total capacitance decreases from ~20 pF at 0 V to ~10 pF at 5 V reverse bias. This voltage-dependent behavior is typical of PN-junction TVS devices and must be accounted for in high-precision analog or RF front-end designs where bias stability affects matching.
