Product details
Overview
DESD1P0RFWA-7 from Diodes Incorporated is a low-capacitance, dual-channel ESD protection diode array in SOT323 package, rated for ±30 kV IEC 61000-4-2 contact/air discharge, 70 V reverse working voltage, and 15 A peak pulse current (8/20 µs), designed to safeguard high-speed USB 2.0, HDMI, and MIPI data lines against electrostatic events.
For engineers reviewing the DESD1P0RFWA-7 datasheet, DESD1P0RFWA-7 pinout, DESD1P0RFWA-7 application, or DESD1P0RFWA-7 equivalent, key selection criteria include sub-1.7 pF line-to-ground capacitance at 1 MHz, forward clamping voltage ≤6 V at 3 A, anti-parallel configuration, automotive-grade qualification readiness, and RoHS-compliant green packaging.
Technical Context
This dual-diode array uses an anti-parallel configuration per channel to provide bidirectional transient suppression on high-speed signal pairs. It operates within –65°C to +150°C and delivers 200 mW power dissipation with 625°C/W junction-to-ambient thermal resistance on FR-4 PCBs.
The device achieves low signal distortion via 1.0–1.7 pF total capacitance (line-to-ground, 0 V, 1 MHz), enabling preservation of signal integrity in >480 Mbps USB 2.0 and 1.65 Gbps MIPI D-PHY interfaces while maintaining <100 nA reverse leakage at 70 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV contact & air discharge per IEC 61000-4-2 - meets highest system-level ESD immunity requirements without external shielding |
| Reverse Working Voltage | 70 V - supports protection of 3.3 V, 5 V, and 12 V data buses with margin against overvoltage transients |
| Capacitance (per diode) | 1.0–1.7 pF @ 0 V, 1 MHz - ensures minimal signal attenuation and timing skew on USB 2.0/HDMI differential pairs |
| Peak Pulse Current | 15 A @ 8/20 µs - withstands severe surge events per IEC 61000-4-5 Level 4 without degradation |
| Forward Clamping Voltage | ≤6 V @ 3 A - limits voltage seen by protected ICs to safe levels during ESD strike |
| Operating Temperature | –65°C to +150°C - qualified for under-hood automotive and industrial edge environments |
Pinout & Package
Package: SOT323 - ultra-compact 3-pin surface-mount plastic package (2.15 mm × 2.10 mm × 0.95 mm), moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to protected signal line; forms anti-parallel pair with Pin 3 for bidirectional clamping |
| Pin 2 | Cathode (Common) | Shared cathode node tied to ground plane; enables compact dual-diode layout with single return path |
| Pin 3 | Cathode of Channel 1 | Paired with Pin 1 to implement symmetrical clamping; identical to Pin 1 but reversed polarity |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Anti-parallel diode pair per channel enables symmetric clamping of positive/negative transients without polarity constraints |
| Ultra-Low Capacitance | 1.0–1.7 pF line-to-ground minimizes insertion loss and maintains signal rise/fall time integrity on 480 Mbps+ interfaces |
| Automotive-Ready Qualification | Manufactured in IATF 16949-certified facilities; supports PPAP and AEC-Q101 qualification upon request |
| Green & Lead-Free Compliance | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); fully RoHS 3 compliant with annealed matte tin terminations |
Applications
| USB 2.0 Interface Protection | HDMI Data Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in automotive infotainment head units against repeated ESD events during cable insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point, before USB PHY IC. Use Value: Sub-1.7 pF capacitance prevents signal integrity degradation at 480 Mbps, while ±30 kV rating eliminates need for secondary board-level shielding. | Use Scenario: Safeguarding TMDS clock and data channels in portable HDMI transmitters (e.g., smartphone-to-dock adapters) exposed to user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp mounted adjacent to HDMI connector, shunting transients to chassis ground before signal enters retimer or level shifter. Use Value: 70 V VRWM accommodates HDMI's 3.3 V nominal swing with headroom; clamping ≤6 V at 3 A prevents latch-up in downstream SerDes. |
| MIPI D-PHY Camera Interface | Industrial Sensor Hub I/O Protection |
Use Scenario: Shielding high-speed MIPI D-PHY differential pairs (CLK+/−, DATA+/−) between image sensor and SoC in automotive ADAS cameras. IC Role / Device Role / Timing Role: Dual-channel ESD array deployed per lane pair, leveraging anti-parallel topology to preserve common-mode rejection ratio. Use Value: 1.0–1.7 pF capacitance avoids skew between complementary signals; –65°C to +150°C range supports operation in engine bay-mounted modules. | Use Scenario: Protecting analog and digital I/O lines (e.g., I²C, UART, GPIO) of sensor fusion hubs in factory automation controllers subject to maintenance-related ESD. IC Role / Device Role / Timing Role: General-purpose ESD guard for multi-protocol interface banks, using shared cathode to minimize PCB footprint and routing complexity. Use Value: 200 mW power dissipation and 625°C/W RθJA enable reliable operation without thermal derating on standard 2-layer industrial PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G (ON Semi) | Single-channel, 3.3 V VRWM, 0.65 pF typical capacitance, lower clamping voltage (≤11 V @ 1 A) | Optimized for 3.3 V logic rails only; insufficient VRWM margin for 5 V or 12 V bus protection | Select when protecting low-voltage, single-ended I/O with strict capacitance budget (<0.7 pF required) |
| TPD2E001DRYR (TI) | Dual-channel, 5 V VRWM, 1.5 pF typical capacitance, integrated 10 Ω series resistors for EMI filtering | Includes built-in RC filtering; higher series impedance may affect rise time in >100 Mbps links | Prefer for mixed-signal I/O where EMI suppression is prioritized over absolute speed performance |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, DESD1P0RFWA-7 offers broader voltage coverage (70 V VRWM), higher surge robustness (15 A IPP), and automotive-ready manufacturing-making it optimal for high-reliability, multi-rail, high-speed data line protection where design margin and qualification traceability are critical.

FAQ
What is the maximum operating temperature for DESD1P0RFWA-7?
The DESD1P0RFWA-7 is rated for continuous operation from –65°C to +150°C. This full-range specification is validated per JEDEC JESD22-A104 and supports deployment in under-hood automotive environments and industrial control cabinets without thermal derating when mounted per recommended pad layout on FR-4 PCB.
Does DESD1P0RFWA-7 meet AEC-Q101 requirements?
DESD1P0RFWA-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 in standard form, Diodes Incorporated offers AEC-Q101 qualification testing upon customer request with defined test plans covering stress life, HTRB, HTSL, and ESD robustness per AEC-Q101-001 Rev D.
How does the anti-parallel configuration affect circuit layout?
The anti-parallel arrangement (Pin 1 anode / Pin 3 cathode sharing Pin 2 cathode) allows bidirectional clamping without polarity-sensitive placement. Layout requires symmetric trace lengths to both signal lines and direct grounding of Pin 2 to a low-inductance ground plane-no decoupling capacitor needed due to integrated low-impedance path.
Can DESD1P0RFWA-7 protect 10/100 Ethernet PHY lines?
No. DESD1P0RFWA-7 is unsuitable for Ethernet PHY protection due to its 70 V VRWM and lack of integrated common-mode choke functionality. Ethernet requires ≥100 V isolation and differential-mode surge handling per IEEE 802.3; dedicated Ethernet ESD arrays like DIODES APx1004 or ON Semi NUP4114 are appropriate alternatives.
