Product details
Overview
DF5A3.6F(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 3.6 V nominal Zener voltage, ±30 kV IEC61000-4-2 contact discharge immunity, 110 pF typical terminal capacitance at 0 V and 1 MHz, and a compact 5-pin SOT-353 (SC-88A) package. It is deployed on USB 2.0 data lines, HDMI hot-plug detection pins, and SD card interface lines.
For engineers reviewing the DF5A3.6F(TE85L,F) datasheet, DF5A3.6F(TE85L,F) pinout, DF5A3.6F(TE85L,F) application, or DF5A3.6F(TE85L,F) equivalent, key selection criteria include ESD immunity level, low clamping voltage under transient stress, channel-to-channel capacitance matching, and compatibility with high-speed digital interfaces up to 480 Mbps.
Technical Context
This device integrates four independent cathode-anode ESD protection paths in a single ultra-compact surface-mount package. Each channel provides bidirectional clamping via Zener structure with 3.4–3.8 V Zener voltage at 5 mA, and exhibits ≤130 Ω dynamic impedance to ensure fast voltage limiting during ESD events.
The device operates strictly as a transient suppressor - not a voltage regulator - with guaranteed ±30 kV IEC61000-4-2 contact discharge immunity and no DC voltage regulation capability. Its 110 pF typical capacitance at 0 V reverse bias enables use on signal lines where impedance integrity must be preserved below 1 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 3.4–3.8 V at IZ = 5 mA - defines clamping threshold for ESD transients on protected lines |
| ESD immunity | ±30 kV per IEC61000-4-2 contact discharge - validated robustness against human-body-model-like discharges |
| Terminal capacitance (CT) | 110 pF typical at VR = 0 V, f = 1 MHz - low enough for USB 2.0 and SDIO signal integrity |
| Power dissipation (P) | 200 mW - limits sustained power handling; intended only for short-duration ESD pulses |
| Junction temperature (Tj) | −55 to +125 °C - specifies operating envelope for PCB-level thermal design |
| Reverse leakage (IR) | ≤10 μA at VR = 1 V - ensures minimal DC loading on high-impedance signal nodes |
Pinout & Package
DF5A3.6F(TE85L,F) uses the JEITA-standardized 5-pin SOT-353 (SC-88A) package, measuring 2.1 × 1.25 × 0.9 mm with 0.65 mm pitch. The package supports reflow soldering per J-STD-020 and has a typical weight of 0.014 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode 1) | ESD clamp cathode for Channel 1 | Connected to protected signal line; sinks transient current to common anode |
| 2 (Anode) | Common anode node | Shared return path for all four channels; must be tied to system ground or low-impedance reference |
| 3 (Cathode 2) | ESD clamp cathode for Channel 2 | Independent protection path for second signal line; electrically isolated from other cathodes |
| 4 (Cathode 3) | ESD clamp cathode for Channel 3 | Third dedicated protection node; enables simultaneous safeguarding of multi-line interfaces |
| 5 (Cathode 4) | ESD clamp cathode for Channel 4 | Fourth independent cathode; supports full quad-line protection without external routing |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel monolithic integration | Reduces component count by 75% vs. discrete diodes; eliminates inter-channel layout mismatch |
| ±30 kV IEC61000-4-2 contact discharge rating | Exceeds industrial and consumer ESD immunity requirements without external circuitry |
| 110 pF typical capacitance at 0 V | Preserves signal rise/fall times on 480 Mbps USB 2.0 differential pairs |
| 3.6 V nominal Zener voltage | Clamps transients below IC I/O absolute maximum ratings while avoiding false triggering |
| SOT-353 (SC-88A) footprint | Enables placement in <2.5 mm² board area; compatible with standard 0.65 mm pitch pick-and-place |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detect (HPD) |
|---|---|
Use Scenario: Protecting D+ and D− differential pair in smartphone USB OTG ports from user-handling ESD events. IC Role / Device Role / Timing Role: Transient voltage suppressor that clamps fast-rising ESD pulses before they reach the USB PHY's input stage. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while adding <0.5 ns propagation delay due to 110 pF capacitance. | Use Scenario: Safeguarding HDMI HPD pin in set-top boxes against repeated plug/unplug-induced discharges. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed between HPD line and system ground to shunt ±30 kV contact discharges. Use Value: Maintains HPD logic state integrity during hot insertion; avoids false HPD deassertion caused by transient coupling. |
| SD Card Interface | Mobile Display Data Lines |
Use Scenario: Protecting CMD, CLK, and DAT[0:3] lines in microSD sockets of wearables and IoT sensors. IC Role / Device Role / Timing Role: Four-channel ESD suppressor with one cathode per signal line and shared anode to ground. Use Value: Enables full SDIO 4-bit bus protection in <1.5 mm² PCB area; 10 μA max leakage avoids SD card initialization failures. | Use Scenario: Shielding MIPI D-PHY data lanes in AMOLED display modules from assembly-line ESD exposure. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor placed directly at display connector to minimize stub length. Use Value: Limits signal distortion on 1–2 Gbps differential pairs; 3.6 V clamping prevents overvoltage on display driver inputs. |
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 ESD9X3.3S | 3.3 V nominal Zener voltage; 100 pF capacitance; SOD-923 package (2-pin, single-channel) | Requires four separate devices and additional PCB area; lower clamping voltage may increase risk of false triggering on noisy rails | Prefer when tighter voltage tolerance (±5%) or lower capacitance is prioritized over integration density |
| Vishay VEML6030X01 | Not applicable - optical sensor, not ESD protector; excluded from valid alternatives | N/A | Invalid alternative - misidentified part; disregard for ESD protection use cases |
Compared with DF5A3.6F(TE85L,F), ESD9X3.3S offers lower clamping but lacks monolithic quad integration and requires four placements; no valid second alternative meets the same combination of 3.6 V rating, ±30 kV immunity, quad-channel SOT-353 packaging, and 110 pF capacitance.

FAQ
What is the primary function of DF5A3.6F(TE85L,F)?
DF5A3.6F(TE85L,F) is a quad-channel ESD protection diode array designed exclusively for electrostatic discharge suppression on signal lines. It is not rated for continuous voltage regulation or surge protection beyond IEC61000-4-2 ESD events. Its 3.6 V Zener voltage and ±30 kV immunity make DF5A3.6F(TE85L,F) suitable for safeguarding high-speed digital I/O such as USB 2.0 and HDMI HPD pins.
Can DF5A3.6F(TE85L,F) be used as a voltage reference or Zener regulator?
No. DF5A3.6F(TE85L,F) is explicitly designated for ESD protection only and must not be used as a constant-voltage diode. Toshiba's documentation states it is "not intended for any other usage, including without limitation, the constant voltage diode application." DF5A3.6F(TE85L,F) lacks the stability, temperature coefficient, and power handling required for regulation duty.
What does the marking "3.6" on DF5A3.6F(TE85L,F) indicate?
The "3.6" marking on DF5A3.6F(TE85L,F) denotes its nominal Zener voltage of 3.6 V, measured at 5 mA test current. This value falls within the guaranteed range of 3.4–3.8 V and defines the approximate clamping voltage during ESD transients. The marking appears on the top surface of the SOT-353 package per Toshiba's standard labeling convention for the DF series.
Is DF5A3.6F(TE85L,F) RoHS compliant?
Yes, DF5A3.6F(TE85L,F) complies with the EU RoHS Directive. Toshiba confirms RoHS compatibility for this part in its environmental compliance documentation, and the device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. DF5A3.6F(TE85L,F) is suitable for use in consumer electronics sold in regulated markets.
How is the common anode connection implemented in DF5A3.6F(TE85L,F)?
In DF5A3.6F(TE85L,F), Pin 2 serves as the common anode for all four internal Zener diodes. Each cathode (Pins 1, 3, 4, 5) connects to a separate protected signal line, while the shared anode must be routed to a low-impedance system ground plane. This architecture allows simultaneous clamping of multiple lines without inter-channel coupling, and is verified in Toshiba's equivalent circuit diagram.
