Product details
Overview
DESD5V0S1BLD-7B from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It delivers ±30kV IEC 61000-4-2 air/contact ESD immunity, 35–45 pF channel capacitance at 1 MHz, 5 V reverse standoff voltage, and clamps to ≤14 V at 12 A (8/20 μs), enabling robust protection in USB 2.0, HDMI, and audio interface circuits.
For engineers reviewing the DESD5V0S1BLD-7B datasheet, DESD5V0S1BLD-7B pinout, DESD5V0S1BLD-7B application, or DESD5V0S1BLD-7B equivalent, this device is selected for ultra-low-capacitance transient suppression in space-constrained, high-frequency signal paths where leakage (<100 nA at 5 V), low clamping voltage, and RoHS-compliant DFN packaging are critical.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector on single-ended signal lines. Its bidirectional structure enables symmetric clamping for AC-coupled or differential interfaces, with breakdown initiated at 5.5 V (min) and full conduction by 9.5 V (max) under 1 mA test current.
The X2-DFN1006-2 package supports thermal dissipation up to 250 mW on FR-4 PCBs and maintains stable performance across –65°C to +150°C ambient, while its 0.4 mm profile and 35–45 pF capacitance ensure minimal signal integrity impact in >100 Mbps digital links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous working voltage before leakage exceeds 100 nA; sets upper limit for protected line DC bias. |
| Clamping Voltage @ 12 A | ≤14 V - Peak voltage seen by downstream IC during worst-case 8/20 μs surge; ensures safe margin below IC absolute max ratings. |
| Channel Capacitance | 35–45 pF @ 0 V, 1 MHz - Low enough to avoid signal distortion in USB 2.0 (480 Mbps) and audio codec interfaces. |
| ESD Rating (IEC 61000-4-2) | ±30 kV contact/air - Meets highest industrial ESD immunity class without external shielding or layout reinforcement. |
| Peak Pulse Power | 130 W @ 8/20 μs - Sustains multi-pulse ESD events in handheld device drop-test scenarios. |
| Breakdown Voltage | 5.5–9.5 V @ 1 mA - Defines turn-on threshold range; ensures reliable triggering before system-level damage occurs. |
Pinout & Package
Package: X2-DFN1006-2 - 0.4 mm height, 1.0 × 0.6 mm footprint, NiPdAu-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Channel 1) | Connects to protected signal line; forms one side of bidirectional clamping path. |
| Pin 2 | Cathode (Channel 1) | Connects to ground reference; completes low-impedance surge path during ESD event. |
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 |
|---|---|---|---|
| SMAJ5.0A | Unidirectional, DO-214AC package, 600 W peak power, 100 pF capacitance | Requires polarity-aware layout; unsuitable for AC-coupled or differential lines | Select only when protecting DC-biased lines with higher surge energy tolerance needed |
| TPD2E001DRYR | 2-channel, 0.65 pF typical capacitance, 5 V standoff, DSBGA package | Lower capacitance but limited to 8 kV IEC 61000-4-2 contact rating | Prefer for ultra-high-speed interfaces (>1 Gbps) where <1 pF loading is mandatory |
Compared with SMAJ5.0A and TPD2E001DRYR, DESD5V0S1BLD-7B uniquely balances ±30 kV ESD immunity, 35–45 pF capacitance, and bidirectional operation in a 1.0 × 0.6 mm DFN-making it optimal for cost-sensitive, space-constrained USB/audio designs requiring full IEC compliance without sacrificing signal fidelity.

FAQ
What is the maximum operating temperature range for DESD5V0S1BLD-7B?
The DESD5V0S1BLD-7B is rated for operation from –65°C to +150°C junction temperature. Its thermal resistance (RθJA = 500°C/W) assumes mounting on a standard FR-4 PCB per Diodes' AP02001 pad layout. Derating begins above 25°C ambient, with peak pulse power dropping to ~70% at 85°C ambient.
Does DESD5V0S1BLD-7B require orientation-specific placement on the PCB?
No-DESD5V0S1BLD-7B is a bidirectional TVS diode, meaning it provides symmetrical clamping regardless of signal polarity. Pin 1 and Pin 2 are electrically interchangeable for ESD protection purposes; however, consistent orientation simplifies assembly verification and avoids confusion during rework.
How does the 35–45 pF capacitance affect USB 2.0 signal integrity?
At 480 Mbps, DESD5V0S1BLD-7B's 35–45 pF capacitance introduces <0.5 UI jitter and <1 dB insertion loss up to 250 MHz when placed per recommended layout (short traces, ground pour clearance). This meets USB-IF eye diagram mask requirements without requiring equalization or pre-emphasis in host/device PHYs.
Is DESD5V0S1BLD-7B compliant with automotive AEC-Q200 stress testing?
No-DESD5V0S1BLD-7B is not AEC-Q200 qualified. It is specified for commercial and industrial portable electronics. For automotive applications, Diodes offers the D3V3M1U2Q-7, which is AEC-Q200 Grade 2 qualified and features identical electrical specs with enhanced temperature cycling and humidity resistance validation.
