Diodes Incorporated D5V0S1U2LP1610-7

Overview

D5V0S1U2LP1610-7 from Diodes Incorporated is a single-channel, ultra-low-capacitance TVS diode designed for high-surge ESD protection of high-speed data lines. It delivers 6.0V reverse breakdown voltage, ±30kV IEC 61000-4-2 contact/air ESD immunity, and 800pF typical channel capacitance in a U-DFN1610-2 (Type B) package - ideal for protecting USB 2.0, HDMI, and audio interfaces in portable consumer devices.

For engineers reviewing the D5V0S1U2LP1610-7 datasheet, D5V0S1U2LP1610-7 pinout, D5V0S1U2LP1610-7 application, or D5V0S1U2LP1610-7 equivalent, key selection criteria include clamping voltage at 150A (11.5V), thermal resistance (417°C/W), RoHS/Green compliance, and compatibility with automated SMT assembly on FR-4 PCBs with 2oz copper.

Technical Context

This TVS diode operates as a unidirectional transient suppressor with a defined reverse standoff voltage of 5.0V and sharp avalanche turn-on at V_BR ≥ 6.0V. Its low 800pF input capacitance ensures minimal signal distortion on high-frequency I/O lines up to ~100MHz, while maintaining robust 150A peak pulse current handling per 8/20μs waveform.

The device uses a planar silicon junction structure optimized for fast response (<1ns) to ESD events and stable leakage performance (<0.5μA at 5.0V). Thermal design relies on its 417°C/W junction-to-ambient resistance when mounted per Diodes' recommended U-DFN1610-2 pad layout on 2oz FR-4.

FAQ

What is the maximum clamping voltage of D5V0S1U2LP1610-7 at 150A surge current?

The maximum clamping voltage is 11.5V under an 8/20μs pulse waveform at 150A peak current, as specified in the Electrical Characteristics table on page 2 of DS40480 Rev. 4-2. This value ensures downstream logic-level components remain within safe operating voltage limits during worst-case lightning-induced surges.

Is D5V0S1U2LP1610-7 suitable for bidirectional signal lines like USB D+ and D−?

No - D5V0S1U2LP1610-7 is a unidirectional TVS diode intended for use with grounded cathode configuration. For bidirectional protection (e.g., full-duplex USB), two devices must be used back-to-back or a dedicated bidirectional variant such as D5V0F1U2LP1610-7 should be selected.

Does this part meet automotive qualification standards such as AEC-Q101?

No - D5V0S1U2LP1610-7 is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing - customers needing automotive qualification must contact Diodes directly for approved alternatives like the D5V0S1B2LP1610Q-7.

What is the recommended PCB pad layout for optimal thermal and electrical performance?

Diodes specifies a dedicated U-DFN1610-2 (Type B) pad layout with thermal vias to inner ground planes, available at diodes.com/package-outlines.html. The layout uses 0.65mm pad width, 1.9mm length, and 1.3mm spacing to ensure solder joint reliability, minimize inductance, and achieve the rated 417°C/W R_θJA on 2oz FR-4.
