Product details
Overview
DF5A6.2CJE from TOSHIBA is a quad-channel ESD protection diode array designed for high-speed data lines, featuring 6.2 V nominal Zener voltage, 25 pF typical terminal capacitance, ±30 kV IEC61000-4-2 contact discharge immunity, and ultra-compact 5-pin SOT-353 (1-2W1A) package-used in USB 2.0, HDMI, and audio interface protection.
For engineers reviewing the DF5A6.2CJE datasheet, DF5A6.2CJE pinout, DF5A6.2CJE application, or DF5A6.2CJE equivalent, key selection criteria include low-capacitance transient suppression, multi-line integration in space-constrained layouts, guaranteed ESD robustness without clamping voltage drift, and compatibility with 3.3 V/5 V signal rails.
Technical Context
This device implements four independent Zener-based ESD clamps in a single monolithic silicon die, each with cathode-anode configuration optimized for bidirectional transient suppression. It operates exclusively as a transient voltage suppressor-not a voltage regulator-with no DC bias requirement and zero standby current draw beyond leakage.
The 25 pF capacitance is measured at 0 V reverse bias and 1 MHz, ensuring minimal signal integrity impact on high-speed interfaces up to 480 Mbps. Its ±30 kV ESD rating meets IEC61000-4-2 Level 4 under contact discharge, with no functional degradation or parametric shift after stress.

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 NZQ6V2AXV5T1G | Same 6.2 V Zener, 25 pF, SOT-353, but rated only to ±20 kV IEC61000-4-2 contact discharge. | Limited to consumer-grade ESD requirements; not qualified for industrial or automotive touch points. | Select when cost sensitivity outweighs peak ESD immunity needs and layout space permits same footprint. |
| Vishay ESDE05C4 | 6.5 V clamping voltage, 15 pF, SOT-353, ±30 kV rated-but uses TVS diode architecture instead of Zener, with higher leakage (≤5 μA). | Better high-frequency response due to lower capacitance, but higher leakage may affect precision analog sensors. | Prefer for RF-sensitive or ultra-low-noise analog front-ends where <15 pF is critical and leakage is tolerable. |

FAQ
What is the primary function of the DF5A6.2CJE?
The DF5A6.2CJE is a quad-channel Zener-based ESD protection diode array designed solely for transient suppression on high-speed signal lines. It is not intended for voltage regulation or continuous DC operation. Its 6.2 V Zener voltage, 25 pF capacitance, and ±30 kV IEC61000-4-2 rating make the DF5A6.2CJE suitable for protecting USB, HDMI, and audio interfaces from electrostatic discharge without degrading signal integrity.
Can the DF5A6.2CJE be used as a voltage reference or Zener regulator?
No-the DF5A6.2CJE is explicitly designated by Toshiba for ESD protection only and must not be used as a voltage reference or constant-voltage diode. Its electrical characteristics, including dynamic impedance and leakage, are specified only under transient conditions and lack the stability, tolerance, and temperature coefficient required for regulation. Using the DF5A6.2CJE outside its intended ESD-suppression role violates Toshiba's product restrictions and voids reliability guarantees.
What does the "BW" marking on the DF5A6.2CJE indicate?
The "BW" marking is Toshiba's standardized top-side laser mark for the DF5A6.2CJE, confirming authenticity and traceability to the 1-2W1A package variant. It corresponds to the device's unique identification in Toshiba's manufacturing and quality databases and appears consistently across production lots since commercial launch in July 2003. This marking enables quick visual verification that the physical unit matches the DF5A6.2CJE specification and prevents substitution with non-compliant variants.
How is the common-anode configuration implemented in the DF5A6.2CJE?
The DF5A6.2CJE uses Pin 2 as the shared anode connection for all four Zener clamps, with Pins 1, 3, 4, and 5 serving as individual cathodes. This architecture allows simultaneous clamping of up to four signal lines to a single ground reference, minimizing ground loop area and eliminating need for separate anode traces. The common-anode design is integral to the DF5A6.2CJE's compact SOT-353 layout and ensures consistent clamping behavior across channels under multi-pulse ESD stress.
Is the DF5A6.2CJE compliant with RoHS and REACH regulations?
Yes-the DF5A6.2CJE meets EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 requirements for hazardous substances. Toshiba confirms lead-free solderability and halogen-free packaging for this part, with full material declarations available upon request through authorized distribution channels. Compliance documentation for the DF5A6.2CJE is maintained under Toshiba's environmental management system and updated per regulatory revisions through its end-of-life date in April 2026.
