Product details
Overview
DESD5V0XA1BCSF-7 from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It features a 5 V reverse standoff voltage, ±16 kV contact/±18 kV air ESD immunity per IEC 61000-4-2, 0.3 pF typical input capacitance, 5.5 A peak pulse current (8/20 µs), and a compact X2-DSN0603-2 chip-scale package - deployed in USB 2.0, HDMI, and audio jack interfaces.
For engineers reviewing the DESD5V0XA1BCSF-7 datasheet, DESD5V0XA1BCSF-7 pinout, DESD5V0XA1BCSF-7 application, or DESD5V0XA1BCSF-7 equivalent, key selection criteria include ultra-low capacitance for signal integrity, certified IEC 61000-4-2 ESD robustness, thermal derating behavior at elevated ambient temperatures, and compatibility with fine-pitch SMT assembly on FR-4 PCBs.
Technical Context
This TVS operates as a clamping device across differential or single-ended signal paths, triggering at ≥6 V breakdown to divert transient energy away from protected ICs. Its low dynamic impedance (0.3 Ω TLP @10 A) ensures rapid voltage suppression during sub-100 ns ESD events.
The device uses silicon avalanche structure with NiAu bump terminals and is optimized for placement directly at I/O connectors. Its thermal resistance (RθJA = 500 °C/W) and 250 mW steady-state power dissipation are defined for standard 2 oz copper FR-4 pad layout per Diodes' recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous working voltage before leakage exceeds 1 µA; sets upper limit for signal swing in protected line |
| Breakdown Voltage | 6 V (min) - Avalanche conduction initiates reliably at ≥6 V, ensuring margin above 5 V operating rail |
| Clamping Voltage | 5.6 V (typ @5.5 A) - Limits transient voltage seen by downstream IC during 8/20 µs surge, preserving logic-level compatibility |
| Peak Pulse Current | 5.5 A - Withstands IEC 61000-4-2 Level 4 ESD surges without degradation when mounted per spec |
| Channel Input Capacitance | 0.3 pF - Enables use on >480 Mbps USB 2.0 and 720p video lines without measurable signal distortion |
| ESD Protection Level | ±16 kV contact / ±18 kV air - Meets highest IEC 61000-4-2 immunity class for handheld end-equipment |
| Package | X2-DSN0603-2 - 0.6 mm × 0.3 mm, 0.3 mm height, 2-terminal chip-scale package for space-constrained I/O routing |
Pinout & Package
Package: X2-DSN0603-2 - ultra-compact, leadless chip-scale package with NiAu solderable bumps; 0.60 mm × 0.30 mm body, 0.3 mm max height, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (bidirectional) | Shared terminal for symmetrical clamping; connects to signal line requiring ESD protection |
| Pin 2 | Cathode (bidirectional) | Shared terminal - forms low-capacitance, symmetric TVS junction between Pin 1 and Pin 2 |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 Compliance | ±16 kV contact / ±18 kV air - validated immunity enables drop-in integration into CE/FCC-certified consumer designs |
| Ultra-Low Capacitance | 0.3 pF typ - preserves edge rate and eye diagram integrity on high-speed serial links up to 480 Mbps |
| Low Clamping Voltage | 5.6 V @5.5 A - limits stress on 5 V tolerant transceivers and prevents false triggering of internal ESD structures |
| Chip-Scale Packaging | X2-DSN0603-2 - eliminates bond wires and parasitic inductance, enabling placement within 2 mm of connector |
| Green & RoHS Compliance | Halogen-free, antimony-free, lead-free - satisfies IPC-1752a reporting and automotive PPAP material declarations |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Lines |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 transceivers against repeated ESD events during cable insertion. IC Role / Device Role / Timing Role: Bidirectional clamping TVS placed immediately adjacent to USB connector to shunt transients before reaching PHY. Use Value: 0.3 pF capacitance avoids signal rise-time degradation; 5.6 V clamping prevents latch-up in 3.3 V USB PHYs. | Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines from user-handling ESD in home theater equipment. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on 5 V-tolerant, open-drain control buses with 100 kHz–400 kHz clock rates. Use Value: Sub-1 pF loading maintains I²C timing margins; ±16 kV contact rating covers real-world hot-plug scenarios. |
| Smartphone Audio Jacks | Industrial Sensor Interfaces |
Use Scenario: Shielding 3.5 mm TRRS microphone and headset detection lines in smartphones from pocket discharge events. IC Role / Device Role / Timing Role: Single-channel bidirectional TVS on analog audio paths where DC bias is near 0 V and signal swing is ±1 V. Use Value: Symmetric clamping avoids signal offset; 5 V standoff permits direct connection to biased audio switches without level-shifting. | Use Scenario: Protecting RS-485 or CAN FD transceiver I/O pins in factory automation nodes exposed to maintenance personnel ESD. IC Role / Device Role / Timing Role: Front-end transient suppressor on differential bus lines operating at ≤12 Mbps with common-mode voltage up to ±7 V. Use Value: 6 V breakdown provides headroom above ±5 V bus common-mode range; 500 °C/W RθJA supports operation at 85 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package; 600 W PPP; 600 pF CIN; unidirectional | Used in board-level power rail protection, not high-speed data lines | Select only for non-signal applications where capacitance >100× higher is acceptable |
| TPD2E001DRYR | 2-channel, 0.9 pF CIN, ±8 kV contact, X2SON-6 package | Targets dual-line protection (e.g., USB D+/D−) with slightly lower ESD rating | Choose when protecting two adjacent lines simultaneously and 0.9 pF remains within signal integrity budget |
Compared with SMAJ5.0A and TPD2E001DRYR, DESD5V0XA1BCSF-7 uniquely delivers sub-0.4 pF capacitance with ±16 kV contact ESD rating in a 2-terminal 0.6 mm × 0.3 mm footprint - making it optimal for miniaturized, high-speed I/O protection where layout area and signal fidelity are critical constraints.

FAQ
What is the maximum operating temperature for DESD5V0XA1BCSF-7?
The device is rated for continuous operation from −55 °C to +150 °C. Its power derating curve shows usable pulse capability down to 25% of peak rating at +125 °C ambient, based on FR-4 PCB mounting with Diodes' recommended 2 oz copper pad layout.
Can DESD5V0XA1BCSF-7 be used on 3.3 V logic lines?
Yes - its 5 V reverse standoff voltage and 5.6 V clamping voltage provide safe margin for 3.3 V systems. The device remains non-conductive below 5 V, and clamps transients before they exceed 3.3 V logic tolerance thresholds, confirmed by TLP testing at 100 ns pulse width.
Is this part qualified for automotive applications?
No - DESD5V0XA1BCSF-7 is not AEC-Q200 qualified. Diodes offers automotive-grade variants (e.g., DESD5V0S1BA-7) with PPAP documentation and IATF 16949 manufacturing; this part is intended for commercial portable electronics per its datasheet scope and qualification statements.
How does the X2-DSN0603-2 package affect solder reflow yield?
The NiAu bump terminations and 0.4 mm pitch enable reliable reflow with standard Type 3 solder paste and profile. Diodes specifies J-STD-020 Level 1 moisture sensitivity, eliminating bake requirements; recommended stencil aperture is 0.55 mm × 0.25 mm to control solder volume and prevent bridging.
