Product details
Overview
DF5A6.2CFU 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 (1-2V1B) package-used in USB 2.0, HDMI, and audio interface protection.
For engineers reviewing the DF5A6.2CFU datasheet, DF5A6.2CFU pinout, DF5A6.2CFU application, or DF5A6.2CFU equivalent, key selection criteria include low-capacitance signal integrity preservation, multi-line ESD clamping capability, compliance with industrial-grade ESD immunity standards, and compatibility with space-constrained PCB layouts requiring discrete channel isolation.
Technical Context
This device integrates four independent cathode-anode ESD protection paths in a single SOT-353 package, each configured as a Zener diode with bidirectional clamping action. It operates exclusively as a transient voltage suppressor-not a voltage regulator-with no DC biasing function or constant-voltage operation intended.
The electrical architecture delivers fast response to ESD events via low dynamic impedance (≤30 Ω) and low leakage (<2.5 μA at 5 V), while maintaining signal fidelity through minimal parasitic capacitance (25 pF typ. at 0 V, 1 MHz). Its junction temperature rating of 150°C supports operation in thermally demanding environments.
Key Specifications

|---|---|
| Zener voltage | 6.2 V (typ.), ensures reliable clamping above 5 V logic rails without false triggering |
| ESD immunity | ±30 kV per IEC61000-4-2 contact discharge, meets highest industrial ESD robustness class |
| Terminal capacitance | 25 pF (typ. at 0 V, 1 MHz), preserves signal integrity on high-speed interfaces up to ~300 Mbps |
| Power dissipation | 200 mW, supports short-duration ESD pulse energy absorption without thermal runaway |
| Junction temperature | 150°C max, enables use in extended-temperature industrial applications |
| Reverse current | ≤2.5 μA at 5 V, minimizes standby power loss and signal loading in always-on interfaces |
Pinout & Package
Package: SOT-353 (JEITA code: 1-2V1B), ultra-compact 5-pin surface-mount package measuring 2.1 × 1.25 × 0.9 mm (L × W × H), optimized for dense layout and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 4 (CATHODE 3) | ESD clamp cathode for Channel 3 | Enables three-line protection without additional components (e.g., HDMI TMDS pairs) |
| 5 (CATHODE 4) | ESD clamp cathode for Channel 4 | Supports full quad-line protection (e.g., stereo audio + mic + side-tone) |
Key Features

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 NUP4201MR6T1G | Single-channel dual-diode array (2 pins), 30 pF capacitance, ±30 kV rating | Requires four separate placements for quad-line protection; higher total board area | Preferred when design allows discrete placement and lower per-channel cost is prioritized |
| Vishay ESDE0402-1R2N | 0402-size single-line ESD diode, 12 pF capacitance, ±25 kV rating | Lower capacitance but reduced ESD robustness; no integrated quad configuration | Chosen where ultra-low capacitance dominates over ESD margin and layout simplicity |
Compared with NUP4201MR6T1G and ESDE0402-1R2N, DF5A6.2CFU uniquely delivers quad-channel integration with 25 pF/±30 kV performance in one SOT-353 package-reducing BOM count, minimizing routing stubs, and ensuring matched channel characteristics critical for differential signaling.

FAQ
What is the primary function of the DF5A6.2CFU?
The DF5A6.2CFU is a quad-channel ESD protection diode array designed exclusively for electrostatic discharge suppression on high-speed signal lines. It is not intended for voltage regulation or continuous power dissipation. Each channel provides bidirectional clamping between its cathode and the common anode, with a nominal Zener voltage of 6.2 V and guaranteed ±30 kV IEC61000-4-2 immunity. DF5A6.2CFU must be used strictly within its specified absolute maximum ratings-including 200 mW power dissipation and 150°C junction temperature-to maintain reliability.
Can DF5A6.2CFU be used as a Zener voltage reference or regulator?
No, DF5A6.2CFU is explicitly designated by Toshiba for ESD protection only and must not be used as a voltage reference or regulator. Its Zener voltage specification (5.8–6.6 V at 5 mA) reflects clamping behavior under transient conditions-not stable DC regulation. The device lacks tight tolerance control, low dynamic impedance under steady-state bias, or thermal stability required for reference applications. Using DF5A6.2CFU outside its intended ESD-only role violates Toshiba's product restrictions and may result in premature failure or system malfunction.
What does the "F" suffix in DF5A6.2CFU indicate?
The "F" in DF5A6.2CFU denotes the tape-and-reel packaging format compliant with JEDEC standard J-STD-020 moisture sensitivity level (MSL) 1, suitable for standard SMT assembly without baking. This suffix differentiates it from tray-packed variants and confirms compatibility with automated pick-and-place equipment. The full marking "DF5A6.2CFU(TE85L,F)" indicates Toshiba's internal lot traceability code (TE85L) and packaging variant (F); the device itself remains electrically and mechanically identical across packaging options.
How is the common anode (Pin 2) typically connected in circuit design?
In most implementations, Pin 2 (ANODE) of DF5A6.2CFU is connected to the local ground plane to enable negative ESD pulse clamping from cathodes to ground, while positive transients are shunted through system-level TVS or power rail decoupling. Alternatively, when protecting lines referenced to VCC, Pin 2 may be tied to a clean 3.3 V or 5 V rail-ensuring clamping occurs between signal and that rail. The choice depends on system-level grounding strategy and whether the protected interface is ground-referenced or rail-referenced; DF5A6.2CFU supports either configuration without modification.
Does DF5A6.2CFU meet RoHS and REACH compliance requirements?
Yes, DF5A6.2CFU complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed by Toshiba's official environmental documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and all homogeneous materials meet threshold limits. For full substance declarations and exemption status, refer to Toshiba's published Environmental Data Sheet for DF5A6.2CFU-available via Aetrix Electronics' component portal or Toshiba's semiconductor website.
