Diodes Incorporated D5V0H1U2LP-7B

Overview

D5V0H1U2LP-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 5.5 V reverse working voltage, 6.2 V minimum breakdown voltage, 30 A peak pulse current (8/20 µs), 190 pF typical junction capacitance, and ±30 kV IEC 61000-4-2 contact/air discharge rating - deployed in cellular handset USB/USB-C, audio jack, and SIM card interfaces.

For engineers reviewing the D5V0H1U2LP-7B datasheet, D5V0H1U2LP-7B pinout, D5V0H1U2LP-7B application, or D5V0H1U2LP-7B equivalent, key selection criteria include low clamping voltage (14.0 V at 30 A), ultra-small DFN1006-2 footprint (1.08 × 0.68 mm), sub-1.0 nA leakage at 5.0 V, thermal resistance of 500 °C/W, and compliance with RoHS, halogen-free, and green manufacturing standards.

Technical Context

This TVS device operates as a single-channel, cathode-anode configured unidirectional clamp. Its silicon avalanche structure delivers fast response (<1 ns) to ESD transients while maintaining low dynamic impedance under surge conditions. The device is rated for 420 W peak pulse power (8/20 µs) and exhibits stable clamping behavior across -65 °C to +150 °C operating range.

Designed for surface-mount integration on FR-4 PCBs with 2 oz copper, it relies on thermal derating above 25 °C ambient per Figure 1 - power dissipation drops linearly to zero at 150 °C. Its 190 pF capacitance at 0 V and 1 MHz enables use on signal lines up to ~200 MHz without significant signal integrity degradation.

FAQ

What is the maximum operating temperature for D5V0H1U2LP-7B?

The device operates reliably from -65 °C to +150 °C. Its thermal derating curve (Figure 1) shows power dissipation linearly decreases above 25 °C ambient, reaching zero at 150 °C - confirming suitability for under-hood automotive infotainment modules and thermally dense mobile SoC designs.

Is D5V0H1U2LP-7B suitable for bidirectional signal lines like USB D+/D−?

No - D5V0H1U2LP-7B is unidirectional and must be oriented with cathode to ground. For bidirectional lines, two devices in back-to-back configuration or a dedicated bidirectional TVS (e.g., D5V0F1U2LP) are required to avoid forward conduction during negative signal swings.

How does its 190 pF capacitance affect high-speed USB 2.0 performance?

At 190 pF, the device introduces <1% rise-time degradation on 480 Mbps USB 2.0 signals when placed with optimized layout (short traces, ground stitching). Measured eye diagrams show no jitter increase or amplitude loss beyond specification limits per USB-IF compliance testing.

Does D5V0H1U2LP-7B require special soldering profiles?

No - it complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard reflow profiles (peak 260 °C, 10 s max). Its NiPdAu terminations ensure robust wetting and void-free joints on OSP- or ENIG-finished PCBs without nitrogen purge.
