Product details
Overview
DT2636-04S-7 from Diodes Incorporated is a 4-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines, featuring ±18 kV contact / ±20 kV air IEC 61000-4-2 compliance, 0.65 pF typical channel-to-GND capacitance at 2.5 V, 5.5 V reverse standoff voltage, and 6.5 A peak pulse current (8/20 µs) per channel - deployed in USB 2.0, HDMI, and Serial ATA interfaces.
For engineers reviewing the DT2636-04S-7 datasheet, DT2636-04S-7 pinout, DT2636-04S-7 application, or DT2636-04S-7 equivalent, key selection criteria include channel capacitance ≤0.75 pF at 1 MHz, clamping voltage ≤9 V at 5 A, breakdown voltage range of 7.0–9.5 V, thermal resistance of 625 °C/W, and SOT363 package compatibility with high-density PCB layouts.
Technical Context
This device implements a monolithic quad-channel TVS structure with bidirectional clamping per channel, optimized for transient suppression on differential or single-ended high-speed signal paths. Each channel provides symmetrical clamping (VCL1 = 6.8 V @ 1 A, VCL2 = 1.5 V @ 1 A) and low dynamic resistance (RDIFF = 0.4 Ω @ 1 A).
It operates across –55°C to +85°C ambient, with derated pulse power above 25°C per Figure 1, and maintains stable capacitance (ΔCCH ≤ 0.04 pF) over input voltage swing - critical for preserving signal integrity in 480 Mbps USB 2.0 and 1.65 Gbps DVI links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±18 kV contact / ±20 kV air per IEC 61000-4-2 - ensures robust handling-level ESD immunity without signal line degradation |
| Channel Capacitance | 0.65 pF typical @ 2.5 V, 1 MHz - preserves signal rise/fall times in USB 2.0 and HDMI 1.4 channels |
| Reverse Standoff Voltage | 5.5 V max - compatible with 3.3 V and 5 V logic rails without leakage-induced false triggering |
| Clamping Voltage | 9.0 V max @ 5 A, 8/20 µs - limits downstream IC stress below absolute maximum ratings of common interface transceivers |
| Breakdown Voltage | 7.0–9.5 V @ 1 mA - guarantees reliable turn-on margin above VRWM while avoiding premature conduction |
| Thermal Resistance | 625 °C/W junction-to-ambient - enables sustained operation under repeated surge events on standard FR-4 PCBs |
Pinout & Package
SOT363 surface-mount package: 6-pin, 2.1 mm × 1.3 mm × 0.9 mm body, matte tin-plated Alloy 42 leadframe, moisture sensitivity level 1, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Channel 1 Anode | ESD current path from protected line CH1 to GND during positive transients |
| Pin 2 | Channel 2 Anode | ESD current path from protected line CH2 to GND during positive transients |
| Pin 3 | No Connect | Internally unconnected; must be left floating or tied to GND per layout guidelines |
| Pin 4 | GND | Common return path for all four channels' transient current dissipation |
| Pin 5 | Channel 4 Anode | ESD current path from protected line CH4 to GND during positive transients |
| Pin 6 | Channel 3 Anode | ESD current path from protected line CH3 to GND during positive transients |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent ESD protection paths in one SOT363 footprint - reduces board area vs. discrete diodes by >60% |
| Low capacitance matching | ΔCCH ≤ 0.04 pF between channels - minimizes skew-induced jitter in differential pairs (e.g., USB D+/D–) |
| Bidirectional clamping | VCL1 = 6.8 V / VCL2 = 1.5 V @ 1 A - protects against both positive and negative ESD events without polarity constraints |
| Green process compliance | Halogen-free (<900 ppm Br+Cl), antimony-free (<1000 ppm), RoHS 2 compliant - meets IPC-1752A Tier 1 reporting requirements |
Applications
| USB 2.0 Interface Protection | HDMI 1.4 Signal Line Protection |
|---|---|
Use Scenario: ESD protection on D+ and D– lines of host/device USB 2.0 ports exposed to user-accessible connectors. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at connector entry point, before PHY transceiver. Use Value: Maintains <100 ps signal distortion at 480 Mbps due to 0.65 pF channel capacitance and matched CCH across channels. | Use Scenario: Clamping induced surges on TMDS clock and data channels in HDMI 1.4 source/sink devices. IC Role / Device Role / Timing Role: Low-capacitance shunt protector aligned with each TMDS pair to preserve eye diagram integrity. Use Value: Limits clamping voltage to ≤9 V at 5 A, preventing damage to HDMI transmitter/receiver I/O cells rated for 10 V absolute max. |
| Serial ATA (SATA II) Data Lanes | DVI-D Dual-Link Video Interface |
Use Scenario: Protecting SATA TX/RX differential pairs in storage controllers and SSD modules subject to board-level ESD. IC Role / Device Role / Timing Role: Per-lane TVS array placed adjacent to SATA connector, minimizing trace inductance in surge path. Use Value: Dynamic resistance of 0.4 Ω ensures fast response (<1 ns) and low overshoot during 8/20 µs transients. | Use Scenario: Shielding DVI-D dual-link pixel clock and RGB data channels from ESD in digital signage and projector designs. IC Role / Device Role / Timing Role: Channel-specific clamp on each of 24 data lines and clock, referenced to common GND plane. Use Value: 0.75 pF max capacitance at 0 V bias prevents attenuation of 165 MHz pixel clock harmonics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel low-capacitance TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | 0.5 pF typical capacitance; lower 5.0 V VRWM; 12 V clamping @ 5 A | Better suited for 3.3 V-only systems with tighter capacitance budget; higher clamping increases risk to 5 V tolerant receivers | Select when system operates exclusively at 3.3 V and requires sub-0.6 pF channel capacitance |
| TPD4E05U06DQAR | 0.5 pF typical; 5.5 V VRWM; 12.5 V clamping @ 5 A; integrated ESD diode + RC filter | Includes series resistor for filtering but adds 5 Ω impedance - unsuitable for >480 Mbps protocols without equalization | Prefer for lower-speed industrial UART/RS-485 where filtering adds value and speed is ≤10 Mbps |
Compared with SP1006-04UTG and TPD4E05U06DQAR, DT2636-04S-7 offers balanced 5.5 V VRWM headroom, moderate 9 V clamping, and verified 0.65 pF performance at 2.5 V bias - making it optimal for mixed-voltage (3.3 V/5 V) high-speed interfaces requiring predictable, low-distortion protection.

FAQ
What is the maximum operating temperature range for DT2636-04S-7?
The DT2636-04S-7 is rated for continuous operation from –55°C to +85°C ambient temperature. Its thermal resistance (RθJA = 625 °C/W) and pulse derating curve (Figure 1) confirm stable performance within this range when mounted on a standard 2 oz copper FR-4 PCB per Diodes' AP02001 pad layout.
Does DT2636-04S-7 require external bias or control signals?
No. DT2636-04S-7 is a passive, bidirectional TVS diode array with no enable pins, control inputs, or bias requirements. It functions solely via avalanche breakdown when transient voltage exceeds its VBR (7.0–9.5 V), automatically clamping surges without power or configuration.
Can DT2636-04S-7 protect both differential and single-ended signals?
Yes. Its quad-channel architecture supports independent protection of either four single-ended lines (e.g., USB ID, VBUS, D+, D–) or two differential pairs (e.g., HDMI TMDS0+/–, TMDS1+/–), provided each channel connects between signal and GND - no cross-channel coupling or shared cathodes exist.
Is the SOT363 package of DT2636-04S-7 compatible with standard reflow profiles?
Yes. With Moisture Sensitivity Level 1 per J-STD-020 and matte tin plating qualified per MIL-STD-202 Method 208, the SOT363 package supports standard Pb-free reflow profiles (peak 260°C, <60 sec above 217°C), including IPC/JEDEC J-STD-020D-compliant thermal cycling.
