Product details
Overview
D5V0Q1B2CSP-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 features a 5.5 V reverse standoff voltage, 6.0 V minimum breakdown voltage, 5.5 pF typical channel capacitance, ±14 kV contact/±15 kV air ESD rating per IEC 61000-4-2, and 3 A peak pulse current capability (8/20 µs), making it suitable for USB 2.0, HDMI, and audio jack interfaces in smartphones and wearables.
For engineers reviewing the D5V0Q1B2CSP-7 datasheet, D5V0Q1B2CSP-7 pinout, D5V0Q1B2CSP-7 application, or D5V0Q1B2CSP-7 equivalent, key selection criteria include low input capacitance for signal integrity, robust IEC-compliant ESD clamping performance, compact chip-scale package footprint, and verified 0.2 Ω dynamic resistance under TLP stress.
Technical Context
This TVS diode operates as a bidirectional clamping device across a single I/O line and ground, with symmetrical avalanche breakdown behavior enabling protection against both positive and negative transients. Its ultra-low 5.5 pF capacitance minimizes signal distortion on high-frequency interfaces up to 500 MHz, while the 7.2 V clamping voltage at 1 A ensures safe voltage limiting during ESD events.
The device uses a silicon die in a leadless chip-scale package (X2-DSN0603-2) with NiAu bumps, delivering thermal resistance of 500 °C/W and 250 mW power dissipation on standard FR-4 PCB layout. Its 0.2 Ω dynamic resistance (TLP, 10 A) supports fast energy absorption without thermal runaway under repetitive surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.5 V - Maximum continuous operating voltage before leakage exceeds 100 nA; defines safe interface voltage margin. |
| Breakdown Voltage (VBR) | 6.0 V (min) - Avalanche conduction initiates reliably at ≥6.0 V, ensuring predictable turn-on during overvoltage. |
| Clamping Voltage (VCL) | 7.2 V @ 1 A - Limits transient voltage to ≤7.2 V during 1 A ESD pulse, protecting downstream IC I/O pins. |
| Peak Pulse Current (IPP) | 3 A @ 8/20 µs - Sustains 3 A surge without failure, meeting IEC 61000-4-5 Level 2 lightning immunity. |
| Channel Capacitance (CT) | 5.5 pF @ 0 V, 1 MHz - Enables use on USB 2.0 (480 Mbps) and audio lines without signal rise-time degradation. |
| ESD Rating | ±14 kV contact / ±15 kV air - Fully complies with IEC 61000-4-2 Level 4, highest industrial ESD immunity class. |
| Dynamic Resistance (RDYN) | 0.2 Ω @ 10 A TLP - Low impedance during transient conduction reduces clamping overshoot and improves protection speed. |
Pinout & Package
Package: X2-DSN0603-2 - ultra-compact leadless chip-scale package measuring 0.600 × 0.300 × 0.300 mm, with NiAu solderable bumps and electrically active side walls requiring controlled reflow to avoid shorts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | I/O Line Terminal | Connected to protected signal line (e.g., USB D+, HDMI TMDS+); forms one side of bidirectional clamping path. |
| Cathode (Pin 2) | GND Reference Terminal | Connected to system ground plane; completes low-inductance return path for ESD current diversion. |
Key Features
| Feature | Design Value |

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 | Unidirectional, 5.0 V VRWM, 600 W peak power, DO-214AC package (4.5 × 3.3 mm) | Requires external series resistor for bidirectional use; unsuitable for high-speed data due to ~200 pF capacitance | Select only for low-frequency DC power rail protection where size and capacitance are non-critical |
| TPD2E001DRYR | 2-channel, 5.5 V VRWM, 12 pF per channel, 0.65 mm × 0.65 mm DRY package, TI proprietary process | Higher capacitance limits use to ≤100 Mbps interfaces; dual-channel reduces component count but increases cost per line | Prefer when protecting two adjacent lines (e.g., I²C SDA/SCL) with shared ground and space allows larger footprint |
Compared with SMAJ5.0A and TPD2E001DRYR, D5V0Q1B2CSP-7 delivers optimal balance of ultra-low capacitance, true bidirectionality, and minimal 0.6 × 0.3 mm footprint-making it uniquely suited for space-constrained, high-speed portable interfaces where signal fidelity and ESD robustness are co-prioritized.

FAQ
What is the maximum operating temperature for D5V0Q1B2CSP-7?
The device supports continuous operation from –65°C to +150°C ambient temperature, validated per JEDEC JESD22-A104. This wide range enables use in automotive infotainment modules and industrial handhelds exposed to extreme thermal cycling, with derating applied above 25°C per the 500 °C/W thermal resistance specification.
Does D5V0Q1B2CSP-7 require external biasing or control signals?
No. D5V0Q1B2CSP-7 is a passive, inherently bidirectional TVS diode that operates without any external power, bias, or control circuitry. It functions solely through avalanche breakdown when transient voltage exceeds its 6.0 V minimum breakdown threshold, making it ideal for zero-footprint, always-on protection schemes.
Can D5V0Q1B2CSP-7 be used on differential high-speed lines like USB 3.0 or PCIe?
No. With 5.5 pF capacitance and 7.2 V clamping at 1 A, D5V0Q1B2CSP-7 is rated for USB 2.0 (480 Mbps) and HDMI 1.4a (1.65 Gbps), but not for USB 3.0 SuperSpeed (5 Gbps) or PCIe Gen2 (5 GT/s), which demand <0.3 pF capacitance and tighter clamping. Use dedicated high-speed arrays like D5V3V5U1UPK for those interfaces.
How is the X2-DSN0603-2 package assembled onto PCBs?
The device uses NiAu bump terminals compatible with standard lead-free reflow profiles (peak 260°C). Diodes specifies a recommended pad layout (0.194 mm × 0.291 mm) and warns against solder or flux contact with electrically active side walls-requiring precise stencil aperture control and post-reflow optical inspection to prevent shorts.
