Product details
Overview
DESD24VF1BLP3-7 from Diodes Incorporated is a bidirectional TVS diode engineered for ultra-low-capacitance ESD protection in high-speed signal lines. It features a 24 V reverse working voltage, 25 V minimum breakdown voltage, 0.3 pF typical capacitance at 0 V, ±12 kV contact/±15 kV air ESD rating per IEC 61000-4-2, and 1 A peak pulse current capability - deployed in USB 2.0, HDMI, and camera interface circuits of smartphones and portable electronics.
For engineers reviewing the DESD24VF1BLP3-7 datasheet, DESD24VF1BLP3-7 pinout, DESD24VF1BLP3-7 application, or DESD24VF1BLP3-7 equivalent, key selection criteria include clamping voltage under 1 A (23 V), dynamic resistance (0.65 Ω), thermal resistance (500 °C/W), and compatibility with 0.6 mm × 0.3 mm DFN packaging for space-constrained PCB layouts.
Technical Context
This TVS diode operates as a bidirectional shunt clamp between I/O and ground, activating during transient overvoltage events to divert surge current while maintaining sub-0.45 pF capacitance across the signal path. Its low dynamic resistance (0.65 Ω) ensures rapid voltage clamping response under TLP testing at 10 A/100 ns.
The device is rated for continuous power dissipation of 250 mW on FR-4 PCB with specified pad layout and derates linearly above +25°C ambient, reaching zero power at +150°C. It supports operation from –65°C to +150°C and meets full RoHS 3, halogen-free, and lead-free compliance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC package (4.5 mm × 2.7 mm), 24 V VRWM, 38.9 V VCL @ 12.3 A, 350 pF CT - 1100× higher capacitance. | Designed for board-level power rail protection, not high-speed data lines. | Select only if protecting low-frequency analog or power lines where capacitance is non-critical. |
| SP1003-02HTG | SOD-882 package (1.0 mm × 0.6 mm), 24 V VRWM, 22 V VCL @ 1 A, 0.35 pF CT - slightly larger footprint, identical clamping performance. | Same signal-line use case but requires revised land pattern; RoHS-compliant but not halogen-free. | Choose when existing layout accommodates 1.0 mm length or halogen-free requirement is secondary. |
Compared with SMAJ24A and SP1003-02HTG, DESD24VF1BLP3-7 delivers the lowest capacitance (0.3 pF) in the smallest footprint (0.62 mm × 0.32 mm), enabling direct integration into next-generation mobile interfaces where signal fidelity and board space are simultaneously constrained.

FAQ
What is the maximum clamping voltage of DESD24VF1BLP3-7 under a 1 A 8/20 µs surge?
The maximum clamping voltage (VCL2) is 23 V when subjected to a 1 A, 8/20 µs transient pulse. This value is measured across the device terminals with specified test conditions and represents the peak voltage imposed on the protected line during the surge event, ensuring compatibility with 3.3 V and lower logic families.
Can DESD24VF1BLP3-7 be used on differential signal pairs like USB D+/D– without degrading signal integrity?
Yes - its 0.3 pF typical capacitance and symmetric bidirectional structure ensure minimal skew and impedance mismatch on differential pairs. Measured insertion loss remains below 0.5 dB up to 1 GHz, and the X2-DFN0603-2 package allows placement within 1 mm of the connector to preserve common-mode rejection.
Is the X2-DFN0603-2 package compatible with standard reflow profiles for lead-free assembly?
Yes - the device is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard Pb-free reflow profiles (peak temperature ≤ 260°C, time above 217°C ≤ 60 seconds). Its matte tin finish ensures reliable solder wetting on OSP- or ENIG-finished PCBs.
Does DESD24VF1BLP3-7 meet automotive qualification standards such as AEC-Q101?
No - this part is not AEC-Q101 qualified. It is designed for commercial and portable consumer applications. For automotive-grade ESD protection, Diodes offers the DZ2404000Q series, which undergoes full AEC-Q101 stress testing and is manufactured in IATF 16949-certified facilities.
