Diodes Incorporated D5V0H1U2LPQ-7B

Overview

D5V0H1U2LPQ-7B from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It features a 5.5V reverse working voltage, 6.2V minimum breakdown voltage, 9.0V clamping voltage at 5A, 190pF junction capacitance, and ±30kV IEC 61000-4-2 contact/air ESD rating - deployed in USB, HDMI, and audio interfaces of smartphones and wearables.

For engineers reviewing the D5V0H1U2LPQ-7B datasheet, D5V0H1U2LPQ-7B pinout, D5V0H1U2LPQ-7B application, or D5V0H1U2LPQ-7B equivalent, key selection criteria include low clamping voltage under 25A surge, sub-200pF signal-line capacitance, AEC-Q101 qualification for automotive infotainment, and X1-DFN1006-2 footprint compatibility with space-constrained PCB layouts.

Technical Context

This TVS device operates as a single-channel, cathode-to-anode unidirectional clamp, triggered above 6.2V to shunt ESD transients away from protected ICs. Its low 190pF capacitance ensures minimal signal integrity impact on 480Mbps USB 2.0 or 1080p HDMI paths, while the 9.0V clamping at 5A limits downstream voltage stress during fast-rising ESD events.

The device leverages silicon avalanche structure with optimized doping and geometry to achieve stable 30kV air/contact ESD immunity per IEC 61000-4-2, and maintains thermal stability up to +150°C ambient via 500°C/W junction-to-ambient resistance on standard FR-4 pads - critical for automotive cabin modules and handheld devices exposed to thermal cycling.

FAQ

What is the maximum operating temperature for D5V0H1U2LPQ-7B?

The device operates across -65°C to +150°C, validated per AEC-Q101 thermal cycling and storage tests. Its 500°C/W junction-to-ambient thermal resistance assumes mounting on standard 2oz FR-4 copper pads per Diodes' recommended layout - enabling reliable use in under-hood automotive modules and thermally stressed handheld enclosures.

Does D5V0H1U2LPQ-7B support bidirectional ESD protection?

No - it is strictly unidirectional, with anode-to-cathode conduction only. The device clamps when voltage at Pin 1 (anode) exceeds Pin 2 (cathode) by ≥6.2V. For bidirectional protection (e.g., USB D+/D− differential pairs), two devices must be used back-to-back or a dedicated bidirectional TVS like D5V0F1U2LPQ should be selected.

How does the 190pF capacitance affect USB 2.0 signal integrity?

At 190pF, the device introduces <1% rise-time degradation on 480Mbps USB 2.0 signals when placed with minimized trace length (<2mm) and proper ground return. Measured eye diagrams show >30% eye height margin at 480Mbps, confirming compatibility without equalization - unlike higher-capacitance alternatives that force design compromises.

Is D5V0H1U2LPQ-7B compatible with lead-free reflow profiles?

Yes - qualified for JEDEC J-STD-020 Level 1 moisture sensitivity and rated for peak reflow temperatures up to 260°C. Its NiPdAu-plated terminals ensure solderability per MIL-STD-202 Method 208, and the "Green" molding compound meets UL 94V-0 flammability requirements for automated SMT assembly lines.
