Product details
Overview
SD05C-7 from Diodes Incorporated is a bidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It delivers 640W peak pulse power, 40A peak pulse current, and 200pF channel capacitance, with 6V minimum breakdown voltage and ±30kV IEC 61000-4-2 contact/air discharge rating - deployed in USB 2.0 interfaces of smartphones and digital cameras.
For engineers reviewing the SD05C-7 datasheet, SD05C-7 pinout, SD05C-7 application, or SD05C-7 equivalent, key selection criteria include clamping voltage at 40A (16.0V), ultra-low input capacitance for signal integrity, bidirectional surge handling, RoHS/Green compliance, and SOD323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This TVS diode operates in bidirectional avalanche mode to clamp both positive and negative transients without polarity dependency. Its low 200pF junction capacitance minimizes signal distortion on high-frequency lines such as USB D+/D−, while maintaining 10.5V clamping at 1A and 16.0V at 40A under 8/20µs pulses.
The device uses a planar silicon junction structure in an SOD323 package with matte tin-plated Alloy 42 leads, rated for -65°C to +150°C operation and compliant with IEC 61000-4-2 (±30kV) and IEC 61000-4-4 (40A EFT). Thermal resistance is 500°C/W on standard FR-4 layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 640W - sustains 8/20µs surges up to 40A without failure |
| Breakdown Voltage (VBR) | 6.0V min at 1mA - ensures reliable conduction onset above 5.5V standoff |
| Clamping Voltage (VCL) | 16.0V max at 40A - limits downstream IC voltage stress during worst-case surge |
| Channel Capacitance (CT) | 200pF max at 0V, 1MHz - preserves signal rise/fall times on USB 2.0 (480Mbps) lines |
| ESD Rating | ±30kV air/contact per IEC 61000-4-2 - exceeds industrial immunity requirements |
| Operating Temp Range | -65°C to +150°C - supports deployment in automotive infotainment and outdoor portable gear |

IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed directly at connector entry point. Use Value: 200pF capacitance avoids signal integrity loss at 480Mbps; 16.0V clamping prevents damage to USB PHY transceivers. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) signal line in portable media adapters exposed to user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance shunt protector between HPD and GND, preserving 5V logic threshold timing. Use Value: 6V VBR aligns with 5V HPD pull-up; ±30kV rating ensures reliability across >10,000 plug/unplug cycles. |
| SD Card Interface Lines | Camera Module Data Bus |

IC Role / Device Role / Timing Role: Per-line TVS on CMD, CLK, DAT0–DAT3 traces adjacent to microSD slot. Use Value: SOD323 footprint allows placement within 2mm of connector; 40A IPP handles multi-event surge accumulation. | Use Scenario: Protecting MIPI CSI-2 clock and data lanes in drone-mounted camera modules operating in dry, high-static environments. IC Role / Device Role / Timing Role: Differential pair TVS on clock (CLKP/CLKN) and data (DAT0P/DAT0N) lanes. Use Value: Symmetrical clamping maintains common-mode noise rejection; 200pF avoids skew between paired signals. |
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; 5.0V VRWM; 600W PPP; 250pF CT | Requires separate devices per polarity; higher capacitance degrades >100Mbps signals | Select only if polarity is fixed and bandwidth <100MHz |
| TPD2E001DRYR | Quad-channel array; 15pF CT; 3.6V VBR; ±8kV ESD | Integrated 2-line solution for USB; lower ESD rating limits ruggedness in handheld use | Prefer for space-constrained USB-only designs where ±30kV not mandated |
Compared with SMAJ5.0A and TPD2E001DRYR, SD05C-7 uniquely balances ±30kV robustness, 200pF signal transparency, and single-line SOD323 simplicity - making it optimal for cost-sensitive, high-volume portable USB/HDMI protection where full IEC 61000-4-2 compliance is mandatory.

FAQ
What is the maximum clamping voltage of SD05C-7 at 40A surge current?
The SD05C-7 exhibits a maximum clamping voltage of 16.0V at 40A peak pulse current under 8/20µs waveform conditions, as specified in its Electrical Characteristics table. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is measured with defined test setup per IEC 61000-4-5.
Can SD05C-7 be used on USB 3.0 SuperSpeed lines?
No - SD05C-7's 200pF channel capacitance introduces excessive signal attenuation and jitter on USB 3.0 (5Gbps) differential pairs, which require sub-1pF protection solutions. It is validated only for USB 2.0 (480Mbps) and lower-speed interfaces like HDMI DDC, SD card CMD/CLK, and camera module control buses.
Is SD05C-7 compatible with lead-free reflow soldering processes?
Yes - SD05C-7 features matte tin-plated Alloy 42 leads and is qualified for lead-free reflow per J-STD-020 Level 1 moisture sensitivity. Its SOD323 package withstands peak temperatures up to 260°C for 10 seconds, matching standard Pb-free SAC305 profile requirements without delamination or parametric shift.
Does SD05C-7 require external series impedance for optimal ESD performance?
No - SD05C-7 is designed for direct placement between signal line and ground with no series resistor required. Its low dynamic impedance and fast response (<1ns) enable effective clamping without added latency or RC filtering; however, PCB trace inductance must be minimized by placing it within 3mm of the protected connector per Diodes' layout guidelines.
