Product details
Overview
DF2S8.2FS from Toshiba Electronic Devices & Storage Corporation is an ESD protection diode designed for bidirectional transient voltage suppression in high-speed data lines. It features a working peak reverse voltage of 6.5 V, zener voltage of 8.2 V (typ.), ±30 kV IEC61000-4-2 contact ESD rating, 0.5 pF typical capacitance, and SOD-923 package for space-constrained USB/USB-C, HDMI, and audio interface protection.
For engineers reviewing the DF2S8.2FS datasheet, DF2S8.2FS pinout, DF2S8.2FS application, or DF2S8.2FS equivalent, key selection criteria include low clamping voltage under 12 V at 1 A, sub-1 pF capacitance for signal integrity preservation, dual-rail ESD robustness, and compatibility with 0.6 mm pitch PCB layouts in portable electronics.
Technical Context
This device implements a silicon epitaxial planar Zener structure optimized for fast response to electrostatic discharge events. Its bidirectional configuration provides symmetrical clamping for both positive and negative transients without polarity constraints.
Designed exclusively for ESD protection-not voltage regulation-the DF2S8.2FS operates within a junction temperature range of −55 °C to +150 °C and exhibits dynamic impedance of 20 Ω (typ.) at 5 mA, enabling effective energy diversion while minimizing voltage overshoot during IEC61000-4-2 pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 6.5 V - Maximum continuous reverse bias before leakage exceeds 0.5 µA; sets upper limit for safe operation in 5 V or 3.3 V signal rails. |
| Zener Voltage (VZ) | 8.2 V (typ.) - Clamping threshold where device begins conducting significantly; ensures protection activation below IC damage thresholds. |
| ESD Withstand (IEC61000-4-2) | ±30 kV contact - Confirmed immunity to worst-case human-body-model ESD events without functional degradation. |
| Total Capacitance | 0.5 pF (typ.) at 0 V, 1 MHz - Enables use on >1 Gbps interfaces (e.g., USB 3.2 Gen 1, HDMI 1.4) without signal distortion. |
| Dynamic Impedance | 20 Ω (typ.) at 5 mA - Low impedance maintains tight clamping voltage (<12 V at 1 A pulse), limiting stress on downstream ICs. |
| Package | SOD-923 - 0.6 mm × 0.3 mm footprint with 0.2 mm pitch; supports ultra-dense routing in smartphones and wearables. |
Pinout & Package
SOD-923 surface-mount package with 2-terminal configuration: cathode and anode terminals arranged linearly for automated placement. Weight: 0.55 mg (typ.). Dimensions conform to JEDEC MO-252 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to protected signal line; serves as reference node for bidirectional clamping action. |
| 2 | Anode | Connected to ground plane; completes current path during ESD event to shunt transient energy away from IC inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Clamps both positive and negative transients symmetrically-no need for polarity-aware layout or external biasing. |
| Ultra-Low Capacitance | 0.5 pF typical enables integration into high-speed differential pairs (e.g., USB D+/D−, HDMI TMDS) without degrading eye diagram margin. |
| High ESD Robustness | ±30 kV contact discharge rating exceeds IEC61000-4-2 Level 4 requirements by 2×, supporting field-reliable consumer product certification. |
| Small Outline Package | SOD-923 footprint (0.6 mm × 0.3 mm) reduces board area by >50% vs. SOD-523, critical for slim mobile form factors. |
Applications
| USB 3.2 Gen 1 Interface Protection | HDMI 1.4 Signal Line Protection |
|---|---|
Use Scenario: Protects SuperSpeed USB data lanes from ESD events during cable insertion/removal in laptops and docking stations. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: 0.5 pF capacitance preserves signal integrity up to 5 Gbps; ±30 kV rating eliminates need for secondary protection stages. | Use Scenario: Shields TMDS clock and data channels in flat-panel displays and set-top boxes against handling ESD. IC Role / Device Role: Low-capacitance clamp between differential pairs and chassis ground. Use Value: Sub-12 V clamping voltage at 1 A prevents HDMI receiver latch-up; SOD-923 allows placement within 2 mm of connector. |
| Smartphone Audio Jack ESD Guard | Industrial Sensor Interface Protection |
Use Scenario: Safeguards 3.5 mm TRRS microphone and headset lines in handheld devices exposed to frequent user contact. IC Role / Device Role: Dual-rail ESD suppressor across mic bias, ground, and audio return paths. Use Value: 6.5 V VRWM ensures compatibility with 5 V mic bias supplies; 0.55 mg weight avoids mechanical stress on flex circuits. | Use Scenario: Protects analog sensor outputs (e.g., temperature, pressure) in factory automation equipment subject to maintenance-handling ESD. IC Role / Device Role: Standalone transient suppressor on low-bandwidth analog lines interfacing to microcontrollers. Use Value: −55 °C to +150 °C operating range supports deployment in uncontrolled industrial enclosures; no derating needed below 125 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X5.0ST5G | Unidirectional; 5.0 V VRWM; 0.65 pF capacitance; SOD-923 package. | Requires separate devices per rail in bidirectional signal paths; higher capacitance may limit >3 Gbps use. | Select when protecting DC-biased single-ended lines (e.g., power supply rails) where polarity is fixed. |
| TPD2E001DRYR | Bidirectional; 5.5 V VRWM; 1.3 pF capacitance; SOT-553 package (1.6 mm × 1.6 mm). | Larger footprint and higher capacitance restrict use in high-speed or ultra-compact designs. | Choose for legacy designs using SOT-553 footprints or where 1.3 pF is acceptable for <480 Mbps USB 2.0. |
Compared with ESD9X5.0ST5G and TPD2E001DRYR, the DF2S8.2FS delivers superior bidirectional clamping symmetry, lower capacitance for high-speed interfaces, and the smallest footprint-making it optimal for next-generation portable electronics requiring IEC61000-4-2 Level 4 compliance in minimal board area.

FAQ
What is the primary function of the DF2S8.2FS?
The DF2S8.2FS is a bidirectional ESD protection diode designed exclusively to suppress electrostatic discharge transients on high-speed signal lines. It is not intended for voltage regulation or overvoltage clamping in power circuits. Its 8.2 V zener voltage and ±30 kV IEC61000-4-2 rating make the DF2S8.2FS suitable for safeguarding USB, HDMI, and audio interfaces against human-body-model ESD events without affecting signal integrity.
Does the DF2S8.2FS support bidirectional signal paths like USB differential pairs?
Yes, the DF2S8.2FS is inherently bidirectional due to its symmetrical Zener structure, allowing it to clamp both positive and negative ESD transients equally. This makes the DF2S8.2FS ideal for placement across differential signal pairs such as USB D+/D− or HDMI TMDS channels without requiring polarity alignment or additional components.
What is the maximum operating temperature for the DF2S8.2FS?
The DF2S8.2FS has a specified junction temperature range of −55 °C to +150 °C and a storage temperature range of −55 °C to +150 °C. It is rated for continuous operation up to +150 °C, making the DF2S8.2FS suitable for use in thermally demanding environments such as enclosed industrial sensors or automotive infotainment modules near heat sources.
Can the DF2S8.2FS be used in place of a TVS diode for surge protection?
No-the DF2S8.2FS is qualified only for ESD protection per IEC61000-4-2 (±30 kV contact) and is not rated for higher-energy surge events defined by IEC61000-4-5. Its 1 A peak pulse current rating and low clamping voltage are optimized for nanosecond-scale ESD spikes, not millisecond surges. For lightning or AC-line surge protection, a dedicated TVS diode with higher IPP and energy rating must be used instead of the DF2S8.2FS.
Is the SOD-923 package of the DF2S8.2FS compatible with standard reflow profiles?
Yes, the DF2S8.2FS in SOD-923 package is qualified for standard lead-free reflow soldering per J-STD-020. Its construction supports peak temperatures up to 260 °C for 10 seconds. The 0.55 mg mass and small thermal mass allow uniform heating, and the device's moisture sensitivity level (MSL) is rated at MSL1-enabling floor life unlimited when stored at ≤30 °C/60% RH, as confirmed in Toshiba's official reliability documentation for the DF2S8.2FS.
