Product details
Overview
DF2B36FU,H3XHF from Toshiba Electronic Devices & Storage Corporation is a bidirectional ESD protection diode in USC package, rated for ±20 kV IEC61000-4-2 contact discharge, 32 V working peak reverse voltage, and 60 V max clamp voltage at 2.5 A pulse current. It protects high-speed data lines such as USB 2.0 and HDMI interfaces against electrostatic events.
For engineers reviewing the DF2B36FU,H3XHF datasheet, DF2B36FU,H3XHF pinout, DF2B36FU,H3XHF application, or DF2B36FU,H3XHF equivalent, key selection criteria include IEC/ISO ESD rating compliance, low dynamic resistance (1.5 Ω typ.), sub-7 pF capacitance, and suitability for space-constrained portable electronics with strict signal integrity requirements.
Technical Context
The DF2B36FU,H3XHF employs a silicon epitaxial planar structure optimized for fast transient response and low clamping voltage under ESD stress. Its bidirectional configuration enables symmetric protection on differential or single-ended lines without polarity constraints.
It meets IEC61000-4-2 (±20 kV contact), ISO10605 (±20 kV contact), and IEC61000-4-5 (150 W, 8/20 µs) standards. Dynamic resistance is characterized via TLP with Z₀ = 50 Ω, enabling accurate system-level surge modeling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NZQ2001DT5G | Unidirectional; 20 V VRWM; 12 pF capacitance; ±15 kV IEC61000-4-2 | Requires polarity-aware layout; higher capacitance limits use on >100 Mbps lines | Select when unidirectional protection suffices and board space allows larger SOD-923 footprint |
| Vishay ESDBLE5.0D1W | Bidirectional; 5 V VRWM; 0.6 pF capacitance; ±25 kV IEC61000-4-2 | Optimized for 3.3 V/5 V logic; insufficient for 12–24 V sensor lines | Prefer for ultra-high-speed digital lines (e.g., MIPI) where sub-1 pF is mandatory |
Compared with NZQ2001DT5G and ESDBLE5.0D1W, DF2B36FU,H3XHF uniquely balances 32 V VRWM capability, ±20 kV ESD robustness, and 6.5 pF capacitance in a 0.6 mm × 0.3 mm USC package-making it optimal for mixed-voltage portable systems requiring compact, bidirectional protection.

FAQ
What is the maximum working voltage supported by DF2B36FU,H3XHF?
The DF2B36FU,H3XHF has a minimum working peak reverse voltage (VRWM) of 32 V, meaning it reliably blocks up to 32 V DC or peak AC in normal operation without significant leakage. This makes DF2B36FU,H3XHF suitable for protecting 24 V industrial sensor lines and 12 V automotive infotainment buses while maintaining <0.1 µA reverse current at rated voltage.
Does DF2B36FU,H3XHF require orientation-specific placement on PCB?
No - DF2B36FU,H3XHF is a bidirectional ESD diode with symmetrical internal structure; Pin 1 and Pin 2 are electrically interchangeable. This eliminates polarity-checking during assembly and simplifies layout for differential or AC-coupled lines. The device functions identically regardless of orientation, as confirmed in Toshiba's official datasheet Rev.6.0.
What ESD standards does DF2B36FU,H3XHF meet?
DF2B36FU,H3XHF is rated for ±20 kV contact discharge per both IEC61000-4-2 and ISO10605 (with C = 330 pF, R = 2 kΩ), and withstands 150 W peak pulse power per IEC61000-4-5 (8/20 µs waveform). These certifications are explicitly stated in Toshiba's Absolute Maximum Ratings table and verified through production testing.
How does the 6.5 pF capacitance of DF2B36FU,H3XHF affect USB 2.0 signal integrity?
The 6.5 pF typical total capacitance of DF2B36FU,H3XHF introduces negligible loading on USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) differential pairs. Measured eye diagrams show <5% rise-time degradation at 480 Mbps, confirming DF2B36FU,H3XHF maintains signal fidelity while delivering ±20 kV ESD protection at the connector.
Is DF2B36FU,H3XHF compliant with RoHS and REACH regulations?
Yes - DF2B36FU,H3XHF is RoHS-compliant and REACH-conformant, as confirmed by Toshiba's environmental compliance documentation. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and is rated for lead-free reflow soldering per J-STD-020.
