Diodes Incorporated D2V5L1BS2LP-7B

Overview

D2V5L1BS2LP-7B from Diodes Incorporated is a single-channel bidirectional TVS diode designed for ESD and surge protection of high-speed data lines in portable electronics. It features a 2.6V minimum breakdown voltage, 15A peak pulse current (8/20µs), 30pF typical junction capacitance, ±30kV IEC 61000-4-2 contact/air ESD rating, and clamps to 6.0V at 15A - making it suitable for USB 2.0, HDMI, and audio jack interfaces in smartphones and wearables.

For engineers reviewing the D2V5L1BS2LP-7B datasheet, D2V5L1BS2LP-7B pinout, D2V5L1BS2LP-7B application, or D2V5L1BS2LP-7B equivalent, key selection criteria include low clamping voltage under high IPP, ultra-low capacitance for signal integrity, compact DFN1006-2 footprint, RoHS/Green compliance, and IEC 61000-4-5 surge capability in space-constrained designs.

Technical Context

This TVS operates bidirectionally across two terminals, enabling symmetrical clamping for AC-coupled or differential signal paths. Its silicon avalanche structure delivers fast response (<1 ns) to ESD transients and robust 90W peak pulse power handling per 8/20µs waveform.

The device is optimized for low-capacitance protection without series impedance - critical for preserving signal rise/fall times in 480 Mbps USB 2.0 and 1.5 Gbps HDMI 1.4a interfaces. Thermal design relies on FR-4 PCB copper pad layout per Diodes' recommended footprint, with 500°C/W junction-to-ambient resistance.

FAQ

What is the maximum clamping voltage at 15A surge current?

The D2V5L1BS2LP-7B clamps to 6.0 V under an 8/20 µs 15A peak pulse current, as specified in the Electrical Characteristics table (Note 7). This value ensures protected ICs experience minimal overvoltage stress during IEC 61000-4-5 Level 3 surge events, provided layout follows Diodes' recommended pad dimensions for thermal performance.

Is this TVS unidirectional or bidirectional, and how does that affect circuit placement?

D2V5L1BS2LP-7B is bidirectional - its symmetrical V-I curve enables clamping in both polarities without regard to signal DC bias. This allows direct placement across any two nodes needing protection (e.g., signal-to-ground or differential pair), eliminating orientation concerns during assembly and simplifying layout for AC-coupled interfaces like USB and HDMI.

Can this device protect a 5V logic line without interfering with normal operation?

Yes - with a 2.6V minimum breakdown voltage and 2.5V reverse working voltage (V_RWM), it remains fully non-conductive below 2.5V, making it safe for 3.3V systems. For 5V logic, it is not recommended: V_RWM is too low, risking leakage or premature conduction. Use a higher-V_RWM variant (e.g., D2V8L1BS2LP) instead.

Does the D2V5L1BS2LP-7B require a heatsink or special PCB copper area?

No dedicated heatsink is needed. However, Diodes specifies a defined FR-4 pad layout (1.10 × 0.70 mm with thermal pads) to achieve the rated 500°C/W R_θJA. Deviating from this layout reduces power derating capability - at 75°C ambient, maximum continuous power drops to ~125 mW, well below the 250 mW rating on compliant copper.
