Product details
Overview
DF2B36FU,H3F from Toshiba Electronic Devices & Storage Corporation is a bidirectional ESD protection diode in USC package, designed for I/O line protection with 32 V working peak reverse voltage, ±20 kV IEC61000-4-2 contact ESD rating, and 6.5 pF typical capacitance-used in USB 2.0, HDMI, and audio jack interfaces.
For engineers reviewing the DF2B36FU,H3F datasheet, DF2B36FU,H3F pinout, DF2B36FU,H3F application, or DF2B36FU,H3F equivalent, key selection criteria include clamping voltage at 2.5 A (≤60 V), dynamic resistance (≤8 Ω), low leakage (<0.1 µA at 28 V), and compatibility with high-speed digital interfaces requiring sub-7 pF capacitance.
Technical Context
The DF2B36FU,H3F employs silicon epitaxial planar construction to achieve fast transient response and stable breakdown behavior. Its bidirectional TVS structure provides symmetrical clamping for both positive and negative ESD events per IEC61000-4-2 and ISO10605 standards.
Designed specifically for signal-line protection-not voltage regulation-it operates within a -55 °C to 150 °C junction temperature range and delivers 150 W peak pulse power under 8/20 µs waveform conditions with 2.5 A peak current capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 32 V min - ensures reliable blocking of normal signal swings up to 28 V without leakage or conduction |
| Clamp Voltage (IPP = 2.5 A) | ≤60 V - limits transient overvoltage to safe levels for downstream ICs during ESD strikes |
| ESD Rating (IEC61000-4-2 Contact) | ±20 kV - meets industrial-grade immunity requirements for handheld and peripheral interfaces |
| Total Capacitance (VR = 0 V, 1 MHz) | 6.5 pF typ - preserves signal integrity on high-speed lines like USB 2.0 (480 Mbps) and HDMI DDC |
| Dynamic Resistance | ≤8 Ω - enables rapid voltage clamping with minimal overshoot during fast-rising ESD transients |
| Reverse Leakage Current | <0.1 µA at 28 V - prevents DC loading or battery drain in always-on portable circuits |
Pinout & Package
DF2B36FU,H3F uses the USC (Ultra Small Chip) surface-mount package, measuring 1.0 × 0.6 × 0.35 mm (typ.) and weighing 4.5 mg. It features two terminals in a single-row, no-lead configuration optimized for space-constrained mobile PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode/Cathode (bidirectional) | Shared terminal for symmetrical ESD clamping-no polarity assignment required in layout |
| 2 | Anode/Cathode (bidirectional) | Paired terminal completing the bidirectional TVS path; connects across protected signal line and ground |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Enables single-device protection of AC-coupled or differential signal lines without polarity concerns |

| ±20 kV IEC61000-4-2 Rating | Exceeds Level 4 immunity requirements for consumer and industrial end-equipment certification |
| USC Package (1.0 × 0.6 mm) | Reduces PCB area by >50% vs. SOD-323 while supporting automated placement and reflow |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 ports against user-handling ESD events in smartphones and docking stations. IC Role / Device Role / Timing Role: Bidirectional TVS diode placed between signal line and ground, clamping transients before they reach the USB transceiver. Use Value: 6.5 pF capacitance avoids signal degradation at 480 Mbps; ±20 kV rating ensures pass-fail compliance in IEC61000-4-2 pre-scan testing. | Use Scenario: Safeguarding the bidirectional I²C-based Display Data Channel in HDMI connectors from hot-plug ESD. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on DDC clock/data lines, preserving 100 kHz I²C timing margins. Use Value: ≤0.1 µA leakage prevents pull-up resistor loading; 32 V VRWM accommodates HDMI's 5 V supply margin. |
| Smartphone Audio Jack | Industrial Sensor Interface |
Use Scenario: ESD protection for TRRS microphone and headphone detection lines exposed to frequent cable insertion/removal. IC Role / Device Role / Timing Role: Signal-line TVS placed inline with analog audio paths, operating below audible noise floor. Use Value: Sub-7 pF capacitance avoids high-frequency roll-off; 60 V clamp voltage protects codec inputs rated to ±18 V. | Use Scenario: Shielding 4–20 mA or RS-485 input nodes in PLC modules from field-installed cable ESD. IC Role / Device Role / Timing Role: Primary front-end transient suppressor before signal conditioning circuitry and isolation barriers. Use Value: 150 W peak power handling sustains multiple 8/20 µs surges; -55 °C to 150 °C rating supports extended industrial temperature operation. |
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 ESD9X3.3SFT2G | 3.3 V VRWM, 12 pF capacitance, ±12 kV IEC61000-4-2 rating | Targeted at low-voltage logic rails (e.g., 3.3 V GPIO), not 28 V signal lines | Select only if protecting sub-5 V digital I/O with higher capacitance tolerance |
| Vishay ESDBLE5.0D1W | 5.0 V VRWM, 0.5 pF capacitance, ±25 kV IEC61000-4-2 rating | Optimized for RF antenna lines and ultra-high-speed SerDes, not general-purpose data lines | Prefer for <1 GHz RF paths where sub-1 pF is mandatory; unsuitable for 28 V working voltage |
Compared with ESD9X3.3SFT2G and ESDBLE5.0D1W, DF2B36FU,H3F uniquely balances 32 V VRWM, ±20 kV robustness, and 6.5 pF capacitance-making it the only option validated for 28 V-rated high-speed digital interfaces like USB 2.0 and HDMI DDC without derating or redesign.

FAQ
What is the maximum working voltage supported by DF2B36FU,H3F?
The DF2B36FU,H3F has a minimum working peak reverse voltage (VRWM) of 32 V, meaning it reliably blocks signals up to 28 V DC or peak AC without leakage or conduction. This makes DF2B36FU,H3F suitable for protecting interfaces such as USB 2.0 data lines and HDMI DDC channels that operate near 5 V but require headroom against transient overvoltage.
Does DF2B36FU,H3F meet IEC61000-4-2 Level 4 ESD requirements?
Yes, DF2B36FU,H3F is rated for ±20 kV contact discharge per IEC61000-4-2-exceeding Level 4 (±8 kV contact) by more than double. This rating is verified per Note 1 in the official Toshiba datasheet Rev.6.0 and applies directly to the DF2B36FU,H3F device in its USC package configuration.
What is the typical capacitance of DF2B36FU,H3F and why does it matter?
The DF2B36FU,H3F exhibits 6.5 pF typical total capacitance at 0 V and 1 MHz. This low value minimizes signal distortion and maintains rise time integrity on high-speed lines such as USB 2.0 (480 Mbps), ensuring DF2B36FU,H3F can be deployed without degrading eye diagrams or causing bit errors in data transmission.
Can DF2B36FU,H3F be used in place of a unidirectional ESD diode?
No-DF2B36FU,H3F is inherently bidirectional due to its symmetrical silicon epitaxial planar structure. It must be used across a signal line and ground, not in series with DC-biased lines. Substituting DF2B36FU,H3F for a unidirectional diode (e.g., anode-to-rail configuration) would compromise clamping performance and violate its specified operating mode.
Is DF2B36FU,H3F compliant with RoHS and REACH regulations?
Yes, DF2B36FU,H3F is RoHS-compliant and meets applicable REACH requirements as confirmed by Toshiba's environmental documentation. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and DF2B36FU,H3F is qualified for use in consumer electronics subject to EU regulatory enforcement.
