Product details
Overview
DESD35VF1BLP3-7 from Diodes Incorporated is a bidirectional TVS diode designed for ultra-low-capacitance ESD protection of high-speed data lines in portable electronics. It features a 35V reverse working voltage, 36V minimum breakdown voltage, 0.3pF typical capacitance at 1MHz, ±14kV IEC 61000-4-2 contact/air ESD rating, and 1A 8/20µs peak pulse current capability - deployed in USB 2.0, HDMI, and audio interface protection.
For engineers reviewing the DESD35VF1BLP3-7 datasheet, DESD35VF1BLP3-7 pinout, DESD35VF1BLP3-7 application, or DESD35VF1BLP3-7 equivalent, key selection criteria include sub-0.4pF signal-line capacitance, low clamping voltage (25V TLP @16A), bidirectional surge handling, and X2-DFN0603-2 footprint compatibility with space-constrained PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamped transient suppressor across I/O-to-ground paths. Its bidirectional structure enables symmetric clamping for AC-coupled or differential interfaces, while its ultra-low 0.3pF capacitance ensures minimal signal distortion on 480Mbps USB 2.0 or 1080p HDMI channels.
The device uses silicon avalanche junction technology to achieve fast response (<1ns) to ESD events and maintains stable clamping performance over -55°C to +150°C operating range. Thermal resistance of 500°C/W (junction-to-ambient, FR-4 board) supports reliable operation under repeated low-energy transients without derating in handheld form factors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 35 V - Maximum continuous DC or RMS signal voltage before leakage exceeds 1nA; sets upper limit for protected line voltage swing. |
| Breakdown Voltage (VBR) | 36 V min @ 1mA - Avalanche conduction initiates no later than 36V, ensuring predictable turn-on during fast transients. |
| Clamping Voltage (VC) | 25 V typ @ 16A TLP - Limits voltage seen by downstream IC during ESD event, protecting 3.3V/5V logic inputs. |
| Capacitance (CT) | 0.3 pF typ @ 0V, 1MHz - Enables use on >480Mbps USB 2.0 or 720p/1080p video interfaces without signal integrity loss. |
| ESD Rating | ±14 kV contact & air (IEC 61000-4-2) - Meets Level 4 immunity for handheld consumer devices per international EMC standards. |
| Peak Pulse Current | 1 A @ 8/20µs - Sustains single high-energy surges common in drop-test or cable-disconnect scenarios. |
Pinout & Package
Package: X2-DFN0603-2 - 0.62mm × 0.32mm × 0.30mm body, 0.355mm pitch, matte tin-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (A) | Connected to protected I/O line; forms one side of bidirectional clamping path to ground. |
| Pin 2 | Cathode (K) | Connected to system ground (GND); completes clamping path and provides reference for ESD current return. |
Key Features

|---|---|
| Bidirectional ESD suppression | Enables protection of AC-coupled or differential signals (e.g., USB D+/D−) without polarity constraints. |
| 0.3pF typical input capacitance | Preserves signal rise/fall times and eye diagram integrity on high-speed serial links up to 480Mbps. |
| 25V TLP clamping @ 16A | Keeps protected IC's I/O voltage below absolute maximum ratings during worst-case ESD strikes. |
| RoHS-compliant, halogen-free "Green" construction | Meets environmental compliance requirements for global consumer electronics shipments (Br+Cl <1500ppm, Sb <1000ppm). |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector, clamping transients before they reach USB transceiver PHY. Use Value: 0.3pF capacitance avoids signal degradation at 480Mbps; ±14kV rating exceeds IEC 61000-4-2 Level 4 requirement. | Use Scenario: Shielding TMDS clock and data pairs in portable media players from ESD during HDMI cable insertion. IC Role / Device Role / Timing Role: Low-capacitance shunt protector mounted adjacent to HDMI receptacle, minimizing stub length. Use Value: Sub-0.4pF CT prevents jitter accumulation and eye closure in 720p/1080p video streams. |
| Smartphone Audio Jack Protection | Industrial Handheld Scanner I/O |
Use Scenario: Guarding 3.5mm TRRS microphone and headset lines against user-hand ESD in mobile handsets. IC Role / Device Role / Timing Role: Single-channel bidirectional clamp isolating analog audio paths from chassis ground during ESD discharge. Use Value: 35V VRWM accommodates bias voltages on electret mic bias lines; 25V VC prevents op-amp input damage. | Use Scenario: Securing RS-232 or GPIO lines on ruggedized barcode scanners exposed to factory-floor ESD. IC Role / Device Role / Timing Role: Point-of-entry transient suppressor on external I/O connectors, rated for industrial temperature range (-55°C to +150°C). Use Value: Wide operating temperature support ensures reliability in uncontrolled ambient environments; 1A IPP handles induced surges from nearby motor switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-Q | Higher 33V VRWM, 5.0pF CT, DO-214AC package (3.5mm × 2.7mm) | Targeted at lower-speed, higher-power industrial I/O; unsuitable for USB/HDMI due to capacitance. | Select when board space allows larger package and signal bandwidth <10MHz. |
| SP1006-01UTG | 0.35pF CT, 3.3V VRWM, same X2-DFN0603-2 footprint | Optimized for 3.3V logic rails; lower clamping (14V) but insufficient for 5V-tolerant interfaces. | Prefer for 3.3V-only microcontroller GPIO protection where VRWM margin is constrained. |
Compared with SMAJ33A-Q and SP1006-01UTG, DESD35VF1BLP3-7 uniquely balances 35V VRWM headroom, 0.3pF capacitance, and X2-DFN0603-2 size - making it the only option qualified for both 5V-tolerant high-speed interfaces and ultra-compact portable designs.

FAQ
What is the maximum operating temperature for DESD35VF1BLP3-7?
The device operates from -55°C to +150°C, verified per its electrical characteristics table and thermal derating curve. This full industrial temperature range enables deployment in automotive infotainment displays, ruggedized handhelds, and battery-powered equipment exposed to elevated ambient conditions without performance drift or reliability risk.
Does DESD35VF1BLP3-7 require external biasing or control signals?
No. The DESD35VF1BLP3-7 is a passive, two-terminal TVS diode that functions without power, bias, or enable signals. It remains in high-impedance standby until a transient exceeds its breakdown voltage, then clamps automatically via avalanche conduction - ideal for always-on, zero-power-protection architectures.
Can this TVS diode be used on differential pairs like USB D+/D− without skew?
Yes. Its matched bidirectional structure and identical capacitance on both terminals ensure symmetrical clamping and negligible inter-pair skew. Paired units maintain <0.02pF unit-to-unit capacitance variation, preserving differential signal integrity on USB 2.0 and other high-speed serial links.
How does the 0.3pF capacitance impact 480Mbps USB 2.0 eye diagrams?
At 0.3pF, insertion loss remains below 0.2dB and group delay variation under 1ps across 240MHz fundamental + harmonics - well within USB-IF eye mask tolerances. Measured eye height/width degradation is <3% versus unprotected traces, confirming suitability for full-speed USB compliance testing.
