Product details
Overview
DF2B29FU,H3XHF from Toshiba Electronic Devices & Storage Corporation is an AEC-Q101-qualified ESD protection diode in USC package, featuring ±25 kV IEC61000-4-2 contact ESD immunity, 24 V working peak reverse voltage, and 47 V max clamp voltage at 3 A pulse current. It protects high-speed data lines in automotive infotainment interfaces.
For engineers reviewing the DF2B29FU,H3XHF datasheet, DF2B29FU,H3XHF pinout, DF2B29FU,H3XHF application, or DF2B29FU,H3XHF equivalent, key selection criteria include IEC/ISO ESD rating compliance, low dynamic resistance (9 Ω typ.), sub-10 pF capacitance, and AEC-Q101 qualification for automotive signal line protection.
Technical Context
This bidirectional ESD suppressor uses silicon epitaxial planar technology to deliver fast transient response with low clamping voltage under IEC61000-4-2 and ISO10605 stress. Its 2-pin USC package supports compact PCB layout for USB 2.0, HDMI, and automotive LVDS interfaces.
The device operates with a typical dynamic resistance of 9 Ω and total capacitance of 9 pF at 0 V, enabling minimal signal distortion on high-frequency lines up to 500 MHz while maintaining robust ±30 kV air-gap ESD immunity per IEC61000-4-2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 5.5 V VRWM, 12 pF Ct, no AEC-Q101 qualification | Targeted at consumer USB ports; lacks automotive temperature and reliability validation | Acceptable for non-automotive prototypes where cost is prioritized over qualification |
| ESD5Z3.3T5G | 3.3 V VRWM, 15 pF Ct, ±20 kV IEC contact rating, AEC-Q101 qualified | Optimized for 3.3 V logic rails; higher capacitance limits use on >100 Mbps buses | Preferred for 3.3 V MCU GPIO protection where lower clamping voltage outweighs bandwidth trade-off |
Compared with TPD2E001DRYR and ESD5Z3.3T5G, DF2B29FU,H3XHF uniquely balances 24 V VRWM, 9 pF capacitance, and AEC-Q101 qualification-making it the only option among the three suitable for 24 V automotive data links requiring both high-voltage tolerance and high-speed signal fidelity.

FAQ
What is the maximum clamp voltage of DF2B29FU,H3XHF at 3 A peak pulse current?
The DF2B29FU,H3XHF has a maximum clamp voltage (VC) of 47 V when subjected to a 3 A peak pulse current per IEC61000-4-5 8/20 µs waveform. This value ensures downstream 24 V-rated components remain within safe operating limits during surge events. The typical VC is 37 V at the same condition, confirming consistent clamping performance across production lots.
Is DF2B29FU,H3XHF qualified for automotive applications?
Yes, DF2B29FU,H3XHF is AEC-Q101 qualified, as confirmed in Toshiba's official orderable part number documentation. This qualification covers temperature cycling, humidity bias, mechanical shock, and ESD stress testing required for under-hood and cabin-mounted automotive electronics. The device is rated for operation from −55 °C to +150 °C junction temperature.
What package type does DF2B29FU,H3XHF use and what are its dimensions?
DF2B29FU,H3XHF uses the USC (Ultra Small Chip) package, measuring 1.0 mm × 0.6 mm × 0.35 mm with a typical weight of 4.5 mg. Pin 1 and Pin 2 are located on opposing ends of the rectangular body, supporting standard 0402-sized land patterns. The package is RoHS compliant and compatible with lead-free reflow profiles.
How does the 9 pF capacitance of DF2B29FU,H3XHF affect high-speed signal integrity?
The 9 pF typical total capacitance of DF2B29FU,H3XHF minimizes loading on high-speed lines: it introduces <0.1 dB insertion loss at 500 MHz and preserves rise times below 1 ns on USB 2.0 D+ and D− signals. This enables reliable use on 480 Mbps interfaces without equalization or layout compensation, unlike higher-capacitance alternatives that degrade eye diagrams.
What standards does DF2B29FU,H3XHF meet for ESD immunity?
DF2B29FU,H3XHF meets IEC61000-4-2 (±25 kV contact, ±30 kV air), ISO10605 (contact and air variants), and IEC61000-4-5 (140 W peak pulse power) standards. These ratings are verified per Toshiba's Rev. 3.0.A datasheet and apply directly to the DF2B29FU,H3XHF variant-not inferred from family-level data.
