Product details
Overview
GSOT05-E3-08 from Vishay Semiconductors is a single-line bidirectional asymmetrical ESD protection diode in SOT-23 package, rated for 5 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, and 480 W peak pulse power (8/20 μs), deployed on high-speed data lines such as USB 2.0 or HDMI interfaces.
For engineers reviewing the GSOT05-E3-08 datasheet, GSOT05-E3-08 pinout, GSOT05-E3-08 application, or GSOT05-E3-08 equivalent, key selection criteria include clamping voltage at 30 A (≤16 V), low capacitance at 2.5 V (≤150 pF), AEC-Q101 qualification readiness, and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The GSOT05-E3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: reverse clamping occurs above 6.8 V (typ.) breakdown, while forward clamping holds near 1.0–1.2 V up to 30 A, enabling low-voltage signal integrity preservation during negative transients. Its internal structure uses a single monolithic silicon avalanche diode between pins 1 and 3.
Designed for unidirectional signal/data line protection, it connects pin 1 to ground and pin 3 to the protected line; no biasing or external components are required. The device meets IEC 61000-4-5 (8/20 μs surge) and AEC-Q101 human body model (H3B >8 kV), supporting automotive infotainment and industrial control interface hardening.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage (VRWM) | 5 V - Maximum continuous operating voltage before leakage exceeds 10 μA; defines safe DC operating margin for 3.3 V or 5 V logic interfaces. |
| Reverse Breakdown Voltage (VBR) | 6.0–8.0 V at 1 mA - Threshold where avalanche conduction initiates; ensures robust triggering without premature conduction during normal operation. |
| Clamping Voltage (VC) at 30 A | ≤16 V - Peak voltage seen by protected IC during worst-case 8/20 μs surge; critical for safeguarding 5 V-tolerant receivers. |
| Capacitance at 2.5 V / 1 MHz | ≤150 pF - Low parasitic loading preserves signal rise time and eye diagram integrity on USB 2.0 or LVDS links. |
| ESD Immunity | ±30 kV contact / air discharge per IEC 61000-4-2 - Exceeds Level 4 immunity requirements for consumer and automotive end-equipment. |
| Peak Pulse Power (PPP) | 480 W (8/20 μs) - Sustains transient energy from lightning-induced surges or cable discharge events without failure. |
| Operating Temperature Range | −40 °C to +125 °C - Fully specified for under-hood automotive and industrial environments. |
Pinout & Package
SOT-23 package (JEDEC TO-236AB), 3-pin surface-mount, 2.8 × 2.35 × 1.15 mm, MSL level 1, lead (Pb)-free e3 Sn plating, compatible with standard reflow profiles (peak ≤260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground connection | Low-inductance return path for transient current; must be connected directly to system ground plane with minimal trace length. |
| Pin 2 | No internal connection | Electrically isolated; not bonded internally-must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
| Pin 3 | Protected line input | Connects to the signal/data line requiring ESD protection (e.g., USB D+, HDMI TMDS+); carries both normal signal and clamped surge current. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical (BiAs) Clamping | Enables tight forward clamping (~1.0 V) for negative transients while maintaining higher reverse clamping (~12–16 V) for positive surges-preserving signal swing and reducing ground bounce. |
| AEC-Q101 Qualified Variant Available | Supports automotive-grade reliability validation including HTOL, temperature cycling, and ESD stress-enabling use in ADAS camera links and infotainment displays. |
| Low Capacitance at Operating Bias | 150 pF max at 2.5 V reverse bias ensures <10% signal attenuation at 480 Mbps (USB 2.0 full-speed), avoiding data corruption or jitter accumulation. |
| SOT-23 Footprint Compatibility | Standard 3-pin SOT-23 layout allows drop-in replacement across GSOTxx family (e.g., GSOT04-E3-08, GSOT08-E3-08) without PCB redesign. |
| e3 Sn Plating | Lead-free matte tin termination compliant with RoHS and JEDEC J-STD-020, ensuring reliable solderability and long-term intermetallic stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GSOT04-E3-08 | Lower VRWM (4 V), higher capacitance (≤450 pF at 0 V), same SOT-23 package and BiAs architecture. | Better suited for 3.3 V-only systems with relaxed bandwidth constraints (e.g., UART, I²C). | Select when protecting lower-voltage interfaces where tighter clamping margin is prioritized over signal speed. |

FAQ
What is the maximum clamping voltage of GSOT05-E3-08 during a 30 A IEC 61000-4-5 surge?
The GSOT05-E3-08 exhibits a maximum clamping voltage of 16 V at 30 A peak pulse current (8/20 μs waveform), as specified in the Absolute Maximum Ratings table. This value ensures protected downstream ICs-such as USB 2.0 transceivers rated for 5.5 V absolute maximum-remain within safe operating limits during surge events. The clamping performance is validated per IEC 61000-4-5 test conditions.
Does GSOT05-E3-08 support automotive qualification standards?
Yes, GSOT05-E3-08 is part of the AEC-Q101 qualified GSOTxx family. While the specific GSOT05-E3-08 variant may require ordering with "-HE3-08" or "-HG3-08" suffixes for certified AEC-Q101 lots, its design, process, and test flow are fully aligned with AEC-Q101 requirements-including HBM ESD >8 kV (Class H3B), temperature cycling, and high-temperature operating life. Documentation confirms qualification readiness per Rev. 2.9 (13-Feb-2025).
How does the BiAs-MODE architecture of GSOT05-E3-08 improve signal integrity?
The BiAs-MODE architecture in GSOT05-E3-08 delivers asymmetrical clamping: forward conduction clamps negative transients near 1.0–1.2 V, minimizing ground bounce and DC offset shift, while reverse clamping activates above 6.8 V to protect against positive surges. This preserves the nominal signal swing on bidirectional data lines like USB D+ and avoids false triggering during normal 0–3.3 V or 0–5 V logic transitions-directly enhancing eye diagram margins and bit-error rate performance.
Can GSOT05-E3-08 replace GSOT04-E3-08 without PCB changes?
Yes, GSOT05-E3-08 shares identical SOT-23 package dimensions, pinout (pin 1 = ground, pin 2 = NC, pin 3 = protected line), and footprint with GSOT04-E3-08. No PCB layout modification is required for substitution. However, the higher VRWM (5 V vs. 4 V) and lower capacitance (≤150 pF vs. ≤450 pF) make GSOT05-E3-08 better suited for 5 V-tolerant or higher-speed interfaces-offering improved system margin without hardware revision.
What is the moisture sensitivity level (MSL) rating for GSOT05-E3-08?
GSOT05-E3-08 has a Moisture Sensitivity Level (MSL) rating of Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions (<30 °C / 60% RH) without dry-pack requirements or floor-life limitations. This simplifies handling, assembly planning, and inventory management for high-mix manufacturing environments.
