Product details
Overview
DESD24VF1BLQ-7B from Diodes Incorporated is a bi-directional TVS diode designed for ESD protection of high-speed data lines in automotive interfaces. It features a 24V reverse working voltage, ±13kV contact/±14kV air ESD rating per IEC 61000-4-2, 0.3pF typical capacitance, and AEC-Q101 qualification for use in USB, HDMI, and LVDS ports.
For engineers reviewing the DESD24VF1BLQ-7B datasheet, DESD24VF1BLQ-7B pinout, DESD24VF1BLQ-7B application, or DESD24VF1BLQ-7B equivalent, key selection criteria include ultra-low capacitance for signal integrity, automotive-grade reliability, IEC-compliant ESD robustness, and DFN1006 package compatibility with space-constrained PCB layouts.
Technical Context
This TVS diode operates as a clamping device across differential or single-ended signal lines, activating at 25V breakdown to divert transient energy away from protected ICs. Its low dynamic resistance (0.7Ω) ensures rapid response and minimal voltage overshoot during 1A 8/20µs surges.
The X1-DFN1006-2 package enables integration into high-density automotive PCBs while maintaining thermal performance (RθJA = 250°C/W) and mechanical reliability under thermal cycling. Its NiPdAu-plated terminals support solderability per MIL-STD-202, Method 208.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-Q | DO-214AC package (4.5×2.7mm), 300pF capacitance, 30kW PPP | Not suitable for high-speed data lines due to excessive capacitance; used in power rail protection | Select only for non-signal applications where board space and speed are not constraints |
| SP1003-01UTG | SOD-323 package (1.7×1.25mm), 0.35pF CT, ±15kV ESD rating | Higher ESD rating but larger footprint and no AEC-Q101 qualification | Consider for non-automotive consumer designs needing marginally higher ESD immunity |
Compared with SMAJ24A-Q and SP1003-01UTG, DESD24VF1BLQ-7B uniquely combines automotive qualification, ultra-low capacitance, and sub-1mm² footprint-making it the only viable option for space-limited, high-speed, AEC-compliant signal line protection.

FAQ
What is the maximum operating temperature for DESD24VF1BLQ-7B?
The device supports continuous operation from −55°C to +150°C, validated per AEC-Q101 thermal cycling and high-temperature reverse bias tests. This range covers under-hood and cabin-mounted automotive electronics, including camera modules and display link receivers operating at elevated ambient temperatures.
Does DESD24VF1BLQ-7B require external biasing or control signals?
No. It is a passive, two-terminal TVS diode that operates without bias, power, or control inputs. Conduction occurs automatically when voltage across pins exceeds the 25V breakdown threshold, making it compatible with any signal path regardless of DC common-mode level or directionality.
How does the 0.3pF capacitance impact HDMI 2.0 signal integrity?
At 0.3pF typical, the device adds negligible loading to TMDS differential pairs, preserving rise/fall times and eye opening at 6Gbps. Measured insertion loss remains below 0.5dB up to 3GHz, ensuring compliance with HDMI 2.0 electrical specifications and reducing risk of pixel dropouts or color distortion.
Is the X1-DFN1006-2 package compatible with standard reflow profiles?
Yes. The package is rated for moisture sensitivity level 1 (MSL-1) and qualified for IPC/JEDEC J-STD-020 reflow profiles, including peak temperatures up to 260°C. Its NiPdAu terminations ensure wetting and joint reliability on FR-4 and high-Tg PCBs using standard lead-free solder pastes.
