Product details
Overview
DESD5V0S1BA-7 from Diodes Incorporated is a low-capacitance bidirectional TVS diode designed for ESD protection of high-speed data lines. It delivers ±30kV IEC 61000-4-2 contact/air discharge immunity, 12A peak pulse current (8/20µs), 5V reverse standoff voltage, and 35–45pF channel capacitance at 1MHz, enabling robust protection in USB 2.0, HDMI, and audio interface circuits.
For engineers reviewing the DESD5V0S1BA-7 datasheet, DESD5V0S1BA-7 pinout, DESD5V0S1BA-7 application, or DESD5V0S1BA-7 equivalent, key selection criteria include clamping voltage under 14V at 12A, sub-50pF input capacitance for signal integrity, bidirectional polarity, SOD323 footprint compatibility, and automotive-grade variant availability (DESD5V0S1BAQ).
Technical Context
This TVS diode operates as a voltage-clamped transient suppressor across a single bidirectional channel. Its silicon avalanche structure triggers at 5.5–9.5V breakdown (IR = 1mA) and clamps to ≤14V at 12A peak pulse, limiting surge energy dissipation while maintaining low leakage (<100nA at 5V).
The device uses a planar junction process in an SOD323 package with matte tin-plated Alloy 42 leads. Its thermal resistance (RθJA = 625°C/W) and 200mW steady-state power rating are defined on standard FR-4 PCB layout per Diodes' recommended pad dimensions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30kV air & contact discharge per IEC 61000-4-2 - ensures full-system ESD immunity without external shielding |
| Clamping Voltage | ≤14V at IPP = 12A (8/20µs) - limits downstream IC stress during surge events |
| Reverse Standoff Voltage | 5V - matches 3.3V/5V logic rail interfaces without leakage-induced bias shift |
| Channel Capacitance | 35–45pF at VR = 0V, f = 1MHz - preserves signal integrity up to ~300MHz in USB 2.0 paths |
| Breakdown Voltage | 5.5–9.5V at IR = 1mA - defines reliable turn-on margin above operating voltage |
| Differential Resistance | 0.4Ω at IR = 10A - minimizes dynamic voltage overshoot during fast transients |
Pinout & Package
Package: SOD323 - surface-mount plastic case (1.30 × 1.70 × 0.90 mm), moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode/Cathode (Bidirectional) | Common terminal for symmetrical clamping; no polarity assignment required in layout |
| 2 | Anode/Cathode (Bidirectional) | Paired terminal completing the bidirectional TVS path; interchangeable with Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD suppression | Enables single-device protection of AC-coupled or differential lines (e.g., USB D+/D−) without polarity constraints |
| Low 35–45pF capacitance | Minimizes signal distortion and insertion loss in high-speed digital interfaces up to 480Mbps |
| 12A peak pulse current rating | Supports IEC 61000-4-5 Level 3 surge immunity (1kV line-to-line) when used with series impedance |
| RoHS-compliant & halogen-free | Fulfills IPC-1752A material declaration requirements for consumer and industrial end products |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone charging ports and peripheral docking stations against repeated ESD events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: 35–45pF capacitance avoids signal rise-time degradation while clamping surges to <14V, preserving USB 2.0 eye diagram compliance. | Use Scenario: Safeguarding TMDS clock and data pairs in portable media players and set-top boxes exposed to user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance TVS array element (one per differential pair) mounted adjacent to HDMI receptacle. Use Value: ±30kV ESD immunity prevents latch-up or gate oxide damage in HDMI receiver ICs without degrading 165MHz pixel clock integrity. |
| Smartphone Audio Jack Protection | Industrial Sensor Interface Protection |
Use Scenario: Shielding 3.5mm TRRS microphone and headset lines in mobile handsets from cable-discharge events. IC Role / Device Role / Timing Role: Single-channel bidirectional clamp on each analog audio path (MIC, HP_L, HP_R). Use Value: Sub-50pF capacitance prevents audible pop/noise artifacts; 5V standoff avoids DC bias interference in electret mic bias networks. | Use Scenario: Protecting RS-485 transceiver inputs in factory automation controllers connected to field wiring. IC Role / Device Role / Timing Role: Secondary-level ESD guard before primary surge protection (e.g., GDT + MOV), placed at PCB edge. Use Value: 12A IPP rating handles induced transients from nearby motor switching; bidirectional operation suits half-duplex bus polarity reversal. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Unidirectional, higher capacitance (≈150pF), larger SMA package (4.5×2.7mm) | Requires polarity-aware layout; unsuitable for AC-coupled or differential signals | Select only if board space allows SMA footprint and circuit topology permits unidirectional placement |
| TPD2E001DRYR | 2-channel array, lower capacitance (1.5pF), same SOD-323 size, but 12V standoff | Designed for dual-line protection (e.g., USB D+/D−); not drop-in for single-line 5V rails | Choose when protecting two matched lines simultaneously and 12V clamping is acceptable |
Compared with SMAJ5.0A and TPD2E001DRYR, DESD5V0S1BA-7 uniquely balances 5V standoff, bidirectional symmetry, and 35–45pF capacitance in the compact SOD323 footprint-making it optimal for space-constrained 3.3V/5V data line protection where polarity independence and signal fidelity are critical.

FAQ
What is the maximum clamping voltage of DESD5V0S1BA-7 at 12A peak pulse current?
The maximum clamping voltage is 14V under IEC 61000-4-5 8/20µs waveform conditions. This value is measured across the device terminals with 12A peak current applied, ensuring protected ICs experience no more than 14V transient overvoltage during worst-case surge events.
Can DESD5V0S1BA-7 be used in automotive applications?
Yes - the automotive-qualified variant DESD5V0S1BAQ is available under a separate datasheet (DS31275-Q), qualified to AEC-Q101 with extended temperature range and enhanced reliability testing. The standard DESD5V0S1BA-7 is rated for -55°C to +150°C but lacks AEC-Q101 certification.
How does the 35–45pF capacitance affect USB 2.0 signal integrity?
This capacitance introduces negligible insertion loss below 300MHz, preserving USB 2.0's 480Mbps eye diagram and jitter budget. Measured differential impedance deviation remains within ±2Ω at 240MHz, ensuring compliance with USB-IF signal quality requirements when placed per Diodes' recommended layout.
Is DESD5V0S1BA-7 compatible with lead-free reflow soldering processes?
Yes - it features matte tin finish over Alloy 42 leadframe and is rated for standard Pb-free reflow profiles (peak temperature up to 260°C). Moisture sensitivity level is 1 per J-STD-020, eliminating bake requirements prior to assembly.
