Product details
Overview
DF5A6.2F(TE85L,F) from TOSHIBA is a quad-channel ESD protection diode array designed for high-density I/O line protection in portable electronics. It features 6.2 V nominal Zener voltage, ±30 kV IEC61000-4-2 contact discharge immunity, 55 pF typical terminal capacitance at 1 MHz, and 200 mW power dissipation - enabling robust transient suppression on space-constrained USB, HDMI, or audio interfaces.
For engineers reviewing the DF5A6.2F(TE85L,F) datasheet, DF5A6.2F(TE85L,F) pinout, DF5A6.2F(TE85L,F) application, or DF5A6.2F(TE85L,F) equivalent, key selection criteria include verified ESD immunity level, channel count per package, junction capacitance impact on signal integrity, and thermal derating behavior under repeated pulse stress.
Technical Context
This device implements four independent Zener-clamp diodes in a single ultra-compact surface-mount package, each with cathode-anode configuration optimized for bidirectional ESD clamping. Its 55 pF capacitance (VR = 0 V, f = 1 MHz) and 30 Ω max dynamic impedance (IZ = 5 mA) support high-speed data lines up to ~300 Mbps without significant signal distortion.
The DF5A6.2F(TE85L,F) operates strictly as an ESD suppressor - not a voltage regulator - with guaranteed performance only under transient conditions per IEC61000-4-2. It is not rated for continuous reverse-bias operation or DC voltage regulation, and its 6.2 V Zener voltage (5.8–6.6 V range at IZ = 5 mA) defines clamping threshold, not stable reference output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 6.2 V nominal (5.8–6.6 V min/max at IZ = 5 mA); sets precise clamping threshold for ESD transients |
| ESD immunity | ±30 kV per IEC61000-4-2 contact discharge; validated no-damage performance at system-level ESD testing |
| Terminal capacitance (CT) | 55 pF typical (VR = 0 V, f = 1 MHz); enables use on USB 2.0 and audio lines without excessive signal attenuation |
| Dynamic impedance (ZZ) | ≤30 Ω at IZ = 5 mA; ensures low clamping voltage rise during fast ESD events |
| Power dissipation (P) | 200 mW maximum; limits thermal stress during repetitive ESD pulses in handheld devices |
| Reverse current (IR) | ≤1.0 μA at VR = 3 V; minimizes standby leakage on always-on I/O lines |
Pinout & Package
DF5A6.2F(TE85L,F) uses a 5-pin SOT-353 (SC-88A) package with exposed pad for thermal enhancement. Pin 1 is Cathode 1, Pin 2 is Anode (shared common anode), Pin 3 is Cathode 2, Pin 4 is Cathode 3, and Pin 5 is Cathode 4 - enabling four independent unidirectional clamp paths referenced to a shared anode node.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode 1 | First protected I/O line cathode; connects to signal trace requiring ESD clamping |
| Pin 2 | Anode (common) | Shared anode node tied to ground or low-impedance return path for all four channels |
| Pin 3 | Cathode 2 | Second protected I/O line cathode; electrically isolated from other cathodes |
| Pin 4 | Cathode 3 | Third protected I/O line cathode; supports independent routing of high-speed signals |
| Pin 5 | Cathode 4 | Fourth protected I/O line cathode; enables compact 4-line protection without discrete parts |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent ESD clamps in one 1.6 × 1.6 mm SOT-353 package - reduces PCB area by >75% vs. discrete diodes |
| IEC61000-4-2 compliance | ±30 kV contact discharge rating - exceeds industrial and consumer ESD requirements without external circuitry |
| Low signal-path capacitance | 55 pF typical between cathode and anode - preserves signal integrity on 480 Mbps USB 2.0 differential pairs |
| Controlled Zener voltage tolerance | ±0.4 V (5.8–6.6 V) at 5 mA - ensures predictable clamping onset across temperature and lot variation |

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 | Quad-channel, 5.6 V nominal VZ, 65 pF CT, ±30 kV ESD rating | Higher capacitance limits use to ≤100 Mbps lines; lower clamping voltage suits 3.3 V logic | Select when tighter 5.6 V clamping is required and signal bandwidth <100 Mbps |
| Vishay ESDE0402-1R204E | Single-channel, 12 V VZ, 0.3 pF CT, ±30 kV rating | Ultra-low capacitance but requires four separate placements; no shared anode | Choose for RF or >1 Gbps interfaces where <0.5 pF is mandatory and board space allows discrete placement |
Compared with NUP4201MR6T1G and ESDE0402-1R204E, the DF5A6.2F(TE85L,F) delivers optimal balance of clamping precision (6.2 V), moderate capacitance (55 pF), and integrated quad topology - making it preferred for cost-sensitive, space-constrained USB/audio designs where signal fidelity and part count reduction are critical.

FAQ
What is the primary function of the DF5A6.2F(TE85L,F)?
The DF5A6.2F(TE85L,F) is a quad-channel ESD protection diode array designed exclusively for electrostatic discharge suppression on high-speed I/O lines. It is not intended for voltage regulation or continuous reverse-bias operation. Its 6.2 V Zener voltage defines the clamping threshold during transient events, and it must be used within its absolute maximum ratings - including 200 mW power dissipation and 125°C junction temperature - to ensure reliability. The DF5A6.2F(TE85L,F) complies with IEC61000-4-2 at ±30 kV contact discharge.
Can the DF5A6.2F(TE85L,F) be used as a Zener voltage reference?
No, the DF5A6.2F(TE85L,F) is explicitly designated for ESD protection only and is not qualified for use as a voltage reference or constant-voltage diode. Toshiba's documentation states that it is "not intended for any other usage, including without limitation, the constant voltage diode application." Its Zener voltage tolerance (5.8–6.6 V), dynamic impedance (≤30 Ω), and lack of stability specifications under DC bias make it unsuitable for precision reference applications. The DF5A6.2F(TE85L,F) must be applied strictly per its ESD clamping function.
What is the pin configuration and connection method for the DF5A6.2F(TE85L,F)?
The DF5A6.2F(TE85L,F) uses a 5-pin SOT-353 package with Pin 1 = Cathode 1, Pin 2 = Common Anode, Pin 3 = Cathode 2, Pin 4 = Cathode 3, and Pin 5 = Cathode 4. All cathodes connect to protected signal lines, while the common anode must be tied to a low-impedance ground reference - not VCC or floating nodes - to enable proper clamping. This configuration supports four independent unidirectional ESD paths sharing one return node, minimizing PCB routing complexity. The DF5A6.2F(TE85L,F) does not support bidirectional clamping per channel.
How does the DF5A6.2F(TE85L,F) perform under repeated ESD stress?
The DF5A6.2F(TE85L,F) is rated for ±30 kV IEC61000-4-2 contact discharge with no device damage, but Toshiba cautions that repeated heavy loading - including frequent high-current/voltage transients or thermal cycling - may degrade reliability even within absolute maximum ratings. Designers must apply derating per the Toshiba Semiconductor Reliability Handbook, especially for junction temperature (max 125°C) and power dissipation (200 mW). Long-term performance depends on proper PCB thermal design and limiting pulse repetition rate. The DF5A6.2F(TE85L,F) is not tested for cumulative wear-out beyond standard qualification.
Is the DF5A6.2F(TE85L,F) RoHS compliant and lead-free?
Yes, the DF5A6.2F(TE85L,F) is RoHS compliant and lead-free, consistent with Toshiba's environmental policy and the EU RoHS Directive. The device carries the marking "(TE85L,F)" which denotes tape-and-reel packaging and lead-free finish per J-STD-609. Toshiba confirms compliance through material declarations and third-party testing; however, users must verify latest status via Toshiba's official product page or contact their sales representative, as regulatory requirements may evolve. The DF5A6.2F(TE85L,F) meets JEDEC MSL Level 1 moisture sensitivity standards.
