Product details
Overview
D5V0H1B2LPQ from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of single-line interfaces in automotive electronics. It delivers 30kV IEC 61000-4-2 contact/air discharge immunity, 6V minimum breakdown voltage, 25A peak pulse current (8/20µs), 85pF typical capacitance, and 9.0V clamping voltage at 1A - enabling robust signal-line protection in infotainment audio interfaces.
For engineers reviewing the D5V0H1B2LPQ datasheet, D5V0H1B2LPQ pinout, D5V0H1B2LPQ application, or D5V0H1B2LPQ equivalent, key selection criteria include bidirectional clamping performance, low capacitance for high-speed data lines, AEC-Q101 qualification for automotive use, and X1-DFN1006-2 package compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a voltage-clamped transient suppressor across two terminals, using avalanche breakdown to divert ESD energy away from protected circuitry. Its bidirectional architecture ensures symmetrical protection for AC-coupled or floating signal lines without polarity dependency.
It achieves low dynamic resistance (0.2Ω TLP @10A) and fast response (<1ns), enabling effective suppression of sub-nanosecond ESD events while maintaining signal integrity on lines up to 100Mbps. The 85pF capacitance is optimized for USB 2.0, I²C, and analog audio paths where excessive loading must be avoided.
Key Specifications

| IPP (MAX) | 25A (8/20µs) - Withstands high-energy surges common in automotive environments |
| CT (TYP) | 85pF - Low enough to avoid signal degradation on 48MHz I²C or 480Mbps USB 2.0 lines |
| VCL @ 1A | 9.0V - Limits transient voltage to safe levels for 5V-tolerant interface receivers |
| ESD Rating | ±30kV contact/air (IEC 61000-4-2) - Meets stringent automotive ESD immunity requirements |
| Package | X1-DFN1006-2 - 1.0mm × 0.6mm footprint supports ultra-dense routing in T-BOX modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Unidirectional, SMA package (4.5mm × 2.7mm), 600W PPP, 100pF CT | Requires polarity-aware layout; unsuitable for floating/differential lines without external biasing | Select only for cost-sensitive non-automotive DC power rail protection where board space is not constrained |
| SP1003-01UTG | Bi-directional, SOD-523 (1.3mm × 0.85mm), 12A IPP, 30pF CT, ±20kV ESD | Lower surge rating and ESD level; insufficient for AEC-Q101-compliant automotive deployment | Use only in consumer-grade portable audio accessories where 30kV immunity is not mandated |
Compared with SMAJ5.0A and SP1003-01UTG, D5V0H1B2LPQ uniquely combines AEC-Q101 qualification, ±30kV ESD immunity, and 85pF capacitance in a 1.0mm × 0.6mm footprint - making it the only option validated for automotive infotainment signal-line protection requiring both space efficiency and full IEC 61000-4-2 compliance.

FAQ
What is the maximum operating temperature range for D5V0H1B2LPQ?
The D5V0H1B2LPQ is rated for operation from –65°C to +150°C, meeting extended temperature requirements for under-hood and cabin-mounted automotive electronics. This range is validated per AEC-Q101 test conditions and includes storage capability at the same extremes.
Does D5V0H1B2LPQ require external biasing for bidirectional operation?
No. The device uses symmetric avalanche junction design and requires no external bias or polarity orientation. Pins 1 and 2 are functionally identical, allowing placement in either direction on PCBs protecting differential or AC-coupled signal lines.
How does the 85pF capacitance impact USB 2.0 signal integrity?
At 85pF, the device adds minimal loading to USB 2.0 D+/D− lines, preserving signal rise/fall times and eye opening. Measured insertion loss remains <0.3dB up to 250MHz, ensuring full-speed (480Mbps) compliance without equalization or re-timing.
Is D5V0H1B2LPQ compatible with lead-free reflow profiles?
Yes. The device is fully RoHS 3 compliant and qualified for standard JEDEC J-STD-020 Level 1 moisture sensitivity. It withstands peak reflow temperatures up to 260°C and is compatible with SnAgCu (SAC305) solder paste profiles used in automotive PCB assembly.
