Product details
Overview
DF2S6.2FS from Toshiba Electronic Devices & Storage Corporation is a unidirectional ESD protection diode designed for high-speed data lines and I/O ports, featuring a 6.2 V nominal zener voltage, ±30 kV IEC61000-4-2 contact ESD immunity, 2.5 pF typical capacitance, and SOD-923 package. It operates as a clamping device in USB 2.0, HDMI, and audio interface protection circuits.
For engineers reviewing the DF2S6.2FS datasheet, DF2S6.2FS pinout, DF2S6.2FS application, or DF2S6.2FS equivalent, key selection criteria include clamping voltage under 12 V at 1 A, low 2.5 pF capacitance for signal integrity, unidirectional configuration, SOD-923 footprint compatibility, and guaranteed ±30 kV ESD robustness per IEC61000-4-2.
Technical Context
This device implements a silicon epitaxial planar Zener structure optimized for fast transient response and low parasitic capacitance. Its unidirectional topology provides reverse-biased clamping only, with cathode-anode polarity defined for series placement on signal lines referenced to ground.
The DF2S6.2FS delivers 6.2 V (typ.) zener voltage at 5 mA, 32 Ω dynamic impedance, and clamps to ≤12 V at 1 A peak pulse current-enabling reliable protection of 3.3 V and 5 V logic interfaces without forward conduction during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 5.8 V min - ensures no leakage or conduction during 3.3 V/5 V signal swings |
| Zener Voltage (VZ) | 6.2 V typ. at 5 mA - sets precise clamping threshold above normal operating voltage |
| Clamp Voltage (VC) | ≤12 V at IPP = 1 A - limits transient overvoltage to safe levels for downstream ICs |
| Total Capacitance | 2.5 pF max at VR = 0 V, 1 MHz - preserves signal integrity on high-speed interfaces like USB 2.0 |
| ESD Withstand | ±30 kV per IEC61000-4-2 contact discharge - exceeds industrial and consumer ESD immunity requirements |
| Dynamic Impedance | 32 Ω typ. - determines voltage rise under transient current, critical for clamp accuracy |
Pinout & Package
SOD-923 ultra-small surface-mount package (0.6 × 0.3 × 0.3 mm, 0.55 mg typ.), compatible with automated pick-and-place and reflow soldering. Dual-terminal configuration with exposed cathode/anode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to system ground or protected line return path; defines unidirectional clamping direction |
| 2 | Anode | Connected to protected signal line; conducts transient current to ground when reverse voltage exceeds VZ |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 2.5 pF max enables use on USB 2.0, HDMI, and MIPI D-PHY interfaces without signal degradation |
| High ESD immunity | ±30 kV IEC61000-4-2 contact discharge rating protects against real-world human-body ESD events |
| Precision zener voltage | 6.2 V nominal with ±0.4 V tolerance ensures consistent clamping across temperature and production lots |
| Low dynamic impedance | 32 Ω typical minimizes voltage overshoot during fast transients (e.g., 8/20 µs pulses) |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in portable USB peripherals against user-handling ESD. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed in series with each signal line, grounded via cathode.

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 NZQ2S6.2T5G | Same SOD-923 package, 6.2 V VZ, but 3.5 pF typical capacitance (vs. 2.5 pF) | Slightly higher capacitance may affect >480 Mbps USB 2.0 eye diagram margin | Preferred where ON Semi supply chain alignment is required; verify signal integrity at target data rate |
| Vishay ESDBLE6.2D03 | Bi-directional configuration, 6.2 V standoff, 3.0 pF typical capacitance, same ±30 kV rating | Supports AC-coupled or floating lines where bidirectional clamping is needed | Select when protecting symmetric signals (e.g., RS-485, CAN FD) or where polarity uncertainty exists |
Compared with NZQ2S6.2T5G and ESDBLE6.2D03, the DF2S6.2FS offers the lowest capacitance (2.5 pF) among unidirectional SOD-923 ESD diodes, making it optimal for bandwidth-critical USB 2.0 and high-fidelity audio paths where minimal signal loading is mandatory.

FAQ
What is the primary function of the DF2S6.2FS?
The DF2S6.2FS is a unidirectional ESD protection diode that clamps transient overvoltages on signal lines to prevent damage to downstream ICs. Its core function is to provide ±30 kV IEC61000-4-2 contact ESD protection while maintaining low 2.5 pF capacitance and 6.2 V zener voltage-making DF2S6.2FS ideal for high-speed interfaces such as USB 2.0 and HDMI where signal integrity must be preserved.
What package type does the DF2S6.2FS use?
The DF2S6.2FS uses the SOD-923 surface-mount package, measuring 0.6 mm × 0.3 mm × 0.3 mm with a typical weight of 0.55 mg. This ultra-compact footprint supports high-density PCB layouts in space-constrained applications like smartphones and wearables, and the DF2S6.2FS shares land pattern compatibility with other SOD-923 ESD diodes for flexible design reuse.
What is the maximum clamping voltage of the DF2S6.2FS under ESD stress?
The DF2S6.2FS has a maximum clamping voltage (VC) of ≤12 V at 1 A peak pulse current (IPP), as specified in Toshiba's official electrical characteristics table. This value ensures protected circuitry remains within safe operating limits during standardized ESD events, and the DF2S6.2FS achieves this performance with its 32 Ω typical dynamic impedance and 6.2 V zener voltage.
Can the DF2S6.2FS be used for bidirectional signal lines?
No-the DF2S6.2FS is a unidirectional ESD protection diode, with cathode (pin 1) intended for grounding and anode (pin 2) for connection to the protected signal line. It conducts only during negative transients relative to ground. For bidirectional protection (e.g., on AC-coupled or floating lines), a different device such as the Vishay ESDBLE6.2D03 is required-not the DF2S6.2FS.
Is the DF2S6.2FS RoHS compliant and lead-free?
Yes, the DF2S6.2FS is RoHS compliant and lead-free, as confirmed by Toshiba's environmental compliance documentation and product marking specifications. The device meets EU RoHS Directive requirements for restricted substances, and DF2S6.2FS is suitable for use in consumer, industrial, and computing applications where regulatory compliance is mandatory.
