Product details
Overview
GSOT05C-HT3-GS08 from Vishay Semiconductors is a two-line bidirectional asymmetrical (BiAs) ESD protection diode in LLP75-3B package, rated for ±30 kV IEC 61000-4-2 contact/air discharge, 30 A peak pulse current (pin 1–3 or 2–3), 480 W peak pulse power (pin 1–3), and 5 V reverse standoff voltage. It protects high-speed data lines such as USB 2.0 interfaces against transient overvoltage events.
For engineers reviewing the GSOT05C-HT3-GS08 datasheet, GSOT05C-HT3-GS08 pinout, GSOT05C-HT3-GS08 application, or GSOT05C-HT3-GS08 equivalent, this device supports dual-line BiAs-mode clamping with asymmetric forward/reverse clamping voltages (VF ≤ 4.5 V at 30 A, VC ≤ 16 V at 30 A), low 260–350 pF capacitance at 0 V bias, and RoHS-compliant matte tin (e3) termination.
Technical Context
The GSOT05C-HT3-GS08 implements a two-diode BiAs architecture: pins 1 and 2 connect to protected signal lines (L1, L2), pin 3 is grounded. In normal operation (0–5 V), it presents high impedance (>100 kΩ) with <10 µA leakage. During positive transients, the pin–ground diode breaks down at 6–6.8 V (VBR); during negative transients, it clamps near ground via forward conduction (VF ≤ 4.5 V at 30 A).
It also supports BiSy-mode (single-line symmetrical protection) when pin 3 is left unconnected and pins 1–2 form the protection path - delivering matched ±17–20.4 V clamping at 30 A and 130–175 pF capacitance - enabling flexible layout reuse across differential or single-ended interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV per IEC 61000-4-2 (contact/air); ensures robust immunity in handheld and industrial port interfaces. |
| Reverse Standoff Voltage (VRWM) | 5 V at IR = 10 µA; defines maximum continuous operating voltage before leakage rises significantly. |
| Clamping Voltage (VC) | ≤16 V at IPP = 30 A (BiAs mode, pin 1–3); limits voltage seen by downstream ICs during surge events. |
| Capacitance (CD) | 260–350 pF at 0 V, 1 MHz; balances ESD robustness and signal integrity for USB 2.0 (480 Mbps) compliance. |
| Peak Pulse Current (IPPM) | 30 A per path (pin 1–3 or pin 2–3, 8/20 µs); supports IEC 61000-4-5 Level 3 surge immunity. |
| Package | LLP75-3B (2.0 × 1.25 × 0.55 mm); ultra-compact footprint with MSL level 1 moisture rating and lead-free e3 finish. |
Pinout & Package
GSOT05C-HT3-GS08 uses the LLP75-3B surface-mount package: 3-terminal, 2.0 mm × 1.25 mm × 0.55 mm body, matte tin (e3) plating, UL 94 V-0 molding compound, and MSL level 1 handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Signal Line 1 (L1) Anode/Cathode | Connects to first protected data line; forms one half of BiAs protection path to ground (pin 3). |
| Pin 2 | Signal Line 2 (L2) Anode/Cathode | Connects to second protected data line; forms second half of BiAs protection path to ground (pin 3). |
| Pin 3 | Ground Reference Terminal | Must be connected to system ground; provides common return path for both clamping diodes in BiAs mode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical (BiAs) Clamping | Enables independent optimization: low VF (~1.2 V typ.) for negative transients, controlled VC (≤16 V) for positive surges - preserving signal integrity on bidirectional buses. |
| Dual-Mode Operation (BiAs/BiSy) | Supports both two-line (BiAs) and single-line (BiSy) configurations without redesign - pin 3 unused in BiSy mode, enabling reuse across interface types. |
| Low Capacitance at Operating Bias | 150 pF at VR = 2.5 V (1 MHz); minimizes signal distortion and insertion loss in 480 Mbps USB 2.0 and similar high-speed links. |
| High Surge Robustness | 30 A peak pulse current (8/20 µs) with 480 W peak pulse power (pin 1–3); exceeds IEC 61000-4-5 Level 3 requirements for industrial environments. |
| RoHS & Green Compliance | Lead-free (e3 matte tin), halogen-free molding compound, UL 94 V-0 flammability rating, and zero ozone-depleting substances - meets global environmental mandates. |

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-E3/57T | Single-line unidirectional 5.0 V TVS; 400 W PPP, 30 A IPPM; higher 1000 pF capacitance; DO-214AC package. | Requires separate devices per line; unsuitable for BiAs or BiSy dual-line operation; limited to low-speed interfaces. | Choose only for cost-sensitive, low-frequency (<10 Mbps) applications where board space allows discrete placement per line. |
| TPD2E001DRYR | Two-line BiAs ESD protector; 5.5 V VRWM; 12 V VC @ 1 A; 12 pF typical capacitance; 1.0 × 0.6 mm X2SON package. | Lower clamping voltage and capacitance, but rated only for ±8 kV IEC 61000-4-2 - insufficient for industrial-grade ESD immunity. | Select when ultra-low capacitance is critical (e.g., USB 3.0) and ESD threat level is consumer-grade (±8 kV), not industrial (±30 kV). |
Compared with SMAJ5.0A-E3/57T and TPD2E001DRYR, GSOT05C-HT3-GS08 uniquely delivers ±30 kV ESD immunity in a dual-line BiAs configuration with balanced 5 V standoff and 260–350 pF capacitance - making it optimal for industrial USB 2.0 and HDMI protection where both robustness and signal integrity are required.

FAQ
What is the maximum operating temperature range for GSOT05C-HT3-GS08?
The GSOT05C-HT3-GS08 has a junction temperature range of –40 °C to +125 °C and a storage temperature range of –55 °C to +150 °C. This wide thermal envelope supports deployment in automotive infotainment systems, industrial gateways, and outdoor networking equipment where ambient temperatures fluctuate significantly. The LLP75-3B package maintains electrical performance across this full range without derating.
Can GSOT05C-HT3-GS08 be used in BiSy-mode for single-line protection?
Yes, GSOT05C-HT3-GS08 supports BiSy-mode: leave pin 3 unconnected and use pins 1 and 2 as the protection path. In this configuration, it delivers symmetrical clamping (±17–20.4 V at 30 A) with 130–175 pF capacitance - ideal for protecting single-ended I²C, UART, or CAN lines where bipolar transients occur. Pin 1 and pin 2 are interchangeable in BiSy mode.
What is the reverse leakage current of GSOT05C-HT3-GS08 at its rated standoff voltage?
At VR = 5 V and 25 °C, the GSOT05C-HT3-GS08 exhibits a maximum reverse leakage current (IR) of 10 µA. This low leakage ensures minimal power drain and signal loading on protected lines - critical for battery-powered USB peripherals and always-on communication interfaces where standby current must remain sub-µA.
How does the clamping voltage of GSOT05C-HT3-GS08 compare between BiAs and BiSy modes?
In BiAs mode (pin 1–3 or pin 2–3), GSOT05C-HT3-GS08 clamps to ≤16 V at 30 A; in BiSy mode (pin 1–2), clamping rises to ≤20.4 V at 30 A due to series diode conduction. The BiAs configuration provides lower clamping for asymmetric threats (e.g., USB data lines), while BiSy offers matched response for symmetric signals like RS-232 or legacy serial buses.
Is GSOT05C-HT3-GS08 compatible with lead-free reflow soldering processes?
Yes, GSOT05C-HT3-GS08 is fully compatible with lead-free reflow. Its LLP75-3B package is rated for MSL level 1 per J-STD-020 and withstands peak solder temperatures of 260 °C for 10 seconds at terminals.
