Product details
Overview
DF2S6.2CT from Toshiba is an ESD protection diode in a CST2 package, designed for bidirectional transient suppression on signal lines. It features a 6.2 V nominal Zener voltage, ±30 kV IEC61000-4-2 contact ESD rating, 32 pF typical capacitance at 0 V, and operates from –55 °C to +150 °C. It is used to safeguard USB, HDMI, and audio interface pins against electrostatic discharge.
For engineers reviewing the DF2S6.2CT datasheet, DF2S6.2CT pinout, DF2S6.2CT application, or DF2S6.2CT equivalent, key selection criteria include clamping performance under ±30 kV ESD stress, low dynamic impedance (≤30 Ω), sub-2.5 µA reverse leakage at 5 V, and compatibility with high-speed interfaces requiring ≤32 pF junction capacitance.
Technical Context
The DF2S6.2CT is a silicon epitaxial planar Zener-type ESD suppressor configured as a single bidirectional device. Its internal structure uses a symmetric dual-Zener junction to provide equal clamping in both polarities without external biasing.
It operates exclusively as a transient voltage suppressor - not for regulation - with guaranteed ESD immunity per IEC61000-4-2 contact discharge testing. The device's 32 pF capacitance and low dynamic resistance support signal integrity in data lines up to 480 Mbps (USB 2.0).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal at IZ = 5 mA - sets clamping threshold for overvoltage transients |
| ESD Rating (IEC61000-4-2) | ±30 kV contact discharge - meets highest industrial ESD immunity class |
| Junction Capacitance (Ct) | 32 pF typical at 0 V, 1 MHz - enables use on USB 2.0 and audio differential pairs |
| Dynamic Resistance (ZZ) | ≤30 Ω typical at IZ = 5 mA - ensures low-voltage clamping during fast ESD events |
| Reverse Leakage (IR) | ≤2.5 µA at VR = 5 V - minimizes standby power impact on sensitive analog/digital inputs |
| Operating Temperature | –55 °C to +150 °C - supports automotive under-hood and industrial control environments |
Pinout & Package
DF2S6.2CT is housed in the ultra-compact CST2 surface-mount package (TOSHIBA designation: 1-1P1S), measuring 1.0 × 0.6 × 0.35 mm and weighing 0.7 mg. This two-terminal SOD-923–equivalent footprint supports high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Reference terminal for Zener conduction | Connected to system ground or common reference plane to enable bidirectional clamping |
| 2 (Anode) | Signal-side terminal | Placed in series with protected line (e.g., USB D+, HDMI TMDS+); forms symmetrical clamp path with Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Equal ±30 kV IEC61000-4-2 protection without polarity dependency or external bias |
| Low Capacitance Interface Protection | 32 pF typical enables <480 Mbps data rates without signal distortion or timing skew |
| High-Temperature Reliability | Rated for continuous operation up to +150 °C junction temperature - suitable for engine-control and power-supply proximity |
| Ultra-Small Footprint | CST2 package (1.0 × 0.6 mm) saves >50% board area vs. SOT-23 while maintaining solder joint robustness |

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 Zener voltage (6.2 V), identical CST2 package, but rated for ±25 kV IEC61000-4-2 (contact) | Limited to consumer-grade ESD requirements; not recommended for industrial or automotive deployment where ±30 kV is mandated | Select DF2S6.2CT when full ±30 kV compliance is required; NZQ2S6.2T5G may reduce cost where lower ESD margin is acceptable |
| Vishay ESDBLE6.2D03 | Higher capacitance (45 pF typ.), same ±30 kV rating, SOD-923 package (mechanically compatible but not identical land pattern) | Not suitable for USB 2.0 or HDMI; better suited for lower-speed UART or I²C lines where capacitance tolerance is relaxed | Choose DF2S6.2CT for high-speed interfaces; ESDBLE6.2D03 only if board layout allows SOD-923 rework and speed requirements are ≤1 Mbps |
Compared with NZQ2S6.2T5G and ESDBLE6.2D03, DF2S6.2CT uniquely delivers ±30 kV ESD immunity in a 32 pF, CST2-packaged Zener diode - making it the only option qualified for USB 2.0 and HDMI TMDS protection without signal degradation or layout compromise.

FAQ
What is the primary function of the DF2S6.2CT?
The DF2S6.2CT is a bidirectional ESD protection diode designed exclusively to suppress electrostatic discharge transients on signal lines. It is not intended for voltage regulation or continuous overvoltage clamping. Its 6.2 V Zener voltage, ±30 kV IEC61000-4-2 rating, and 32 pF capacitance make DF2S6.2CT suitable for safeguarding high-speed interfaces such as USB 2.0 and HDMI without degrading signal integrity.
Does the DF2S6.2CT require external biasing to operate?
No, the DF2S6.2CT does not require external biasing. Its symmetric dual-Zener structure enables intrinsic bidirectional clamping behavior - meaning it provides equal protection for positive and negative ESD transients regardless of DC bias on the protected line. This simplifies circuit design and eliminates the need for additional components when implementing DF2S6.2CT in signal path protection schemes.
What is the maximum operating temperature for the DF2S6.2CT?
The DF2S6.2CT has a specified storage temperature range of –55 °C to +150 °C and a junction temperature limit of +150 °C. This allows DF2S6.2CT to be deployed in demanding thermal environments such as automotive under-hood modules, industrial motor drives, and enclosed consumer electronics where ambient temperatures exceed 100 °C.
Can the DF2S6.2CT be used on USB 3.0 or PCIe lanes?
No, the DF2S6.2CT is not recommended for USB 3.0 or PCIe applications. Its 32 pF typical junction capacitance exceeds the <1 pF requirement for SuperSpeed differential signaling. DF2S6.2CT is validated for USB 2.0 (480 Mbps) and HDMI TMDS (up to 2.25 Gbps with margin), but higher-speed protocols demand lower-capacitance solutions. For those interfaces, a dedicated low-Cj ESD array or integrated protection IC should be selected instead of DF2S6.2CT.
Is the DF2S6.2CT RoHS compliant and halogen-free?
Yes, the DF2S6.2CT meets RoHS Directive 2011/65/EU requirements and is halogen-free per JIS C 0950. Toshiba confirms this compliance in its environmental documentation, and the device carries appropriate marking per JEDEC standards. Customers must verify current status via Toshiba's official environmental reports, as DF2S6.2CT's compliance is maintained across all production lots and revisions including Rev. 4.0.A.
