Product details
Overview
GSOT15C-HT3-GS08 from Vishay Semiconductors is a two-line bidirectional asymmetrical (BiAs) ESD protection diode in LLP75-3B package, rated for 15 V reverse standoff voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, and 8 A peak pulse current (IPPM) in line-to-ground configuration-used to safeguard USB 2.0, HDMI, and industrial I/O data lines against electrostatic discharge.
For engineers reviewing the GSOT15C-HT3-GS08 datasheet, GSOT15C-HT3-GS08 pinout, GSOT15C-HT3-GS08 application, or GSOT15C-HT3-GS08 equivalent, this device delivers low clamping voltage (24.8 V at 8 A), sub-120 pF capacitance at 0 V bias, and dual-mode operation (BiAs/BiSy) for flexible system-level transient protection design.
Technical Context
The GSOT15C-HT3-GS08 implements a monolithic dual-diode structure enabling two independent protection paths: Pin 1–Pin 3 and Pin 2–Pin 3 (BiAs mode) when Pin 3 is grounded, or Pin 1–Pin 2 (BiSy mode) with Pin 3 floating. It supports both asymmetrical clamping (forward VF ≈ 1.8 V, reverse VC ≈ 24.8 V at IPPM) and symmetrical clamping (VC ≈ 26.6 V at IPPM in BiSy).
Its LLP75-3B package features 0.75 mm pitch, 1.6 × 1.2 × 0.55 mm footprint, MSL Level 1 rating, and UL 94 V-0 molding compound-optimized for high-density PCB layouts in space-constrained consumer and industrial interfaces requiring robust ESD resilience without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 15 V at IR = 1 µA - defines maximum continuous operating voltage before leakage rises significantly; sets safe margin below 16.5 V logic rail or 15 V analog interface levels. |
| Peak Pulse Current (IPPM) | 8 A (line-to-ground), 8 A (line-to-line) - withstands IEC 61000-4-5 8/20 µs surges up to 230 W peak power without failure. |
| Clamping Voltage (VC) | 24.8 V max at IPPM = 8 A (BiAs), 26.6 V max at IPPM = 8 A (BiSy) - limits transient voltage seen by downstream ICs during ESD events. |
| Diode Capacitance (CD) | 90–120 pF at 0 V, 35 pF at 7.5 V - enables use on 480 Mbps USB 2.0 lines with minimal signal distortion and insertion loss. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 requirements for handheld and portable equipment. |
| Operating Temperature | −40 °C to +125 °C junction - supports automotive under-hood, industrial control, and extended-temperature embedded applications. |
Pinout & Package
GSOT15C-HT3-GS08 uses the LLP75-3B surface-mount package: 1.6 mm × 1.2 mm × 0.55 mm body, 0.75 mm lead pitch, matte tin (e3) termination, RoHS-compliant, non-magnetic, and UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Input/Anode of Diode D1 | Connects to protected signal line L1; forms one ESD path to ground via Pin 3 in BiAs mode. |
| Pin 2 | Input/Anode of Diode D2 | Connects to protected signal line L2; forms second independent ESD path to ground via Pin 3 in BiAs mode. |
| Pin 3 | Common Cathode / Ground Reference | Must be connected to system ground in BiAs mode; left unconnected in BiSy mode for single-line symmetrical protection. |
Key Features
| Feature | Design Value |
|---|---|
| Two-line BiAs protection | Enables simultaneous ESD protection of differential or parallel data lines (e.g., USB D+/D−) with independent clamping thresholds and shared ground return. |
| Low clamping voltage asymmetry | Forward VF ≤ 1.8 V and reverse VC ≤ 24.8 V at 8 A ensures sensitive 3.3 V/5 V receivers remain within safe operating area during transients. |
| Sub-120 pF capacitance | Minimizes signal rise-time degradation and crosstalk on high-speed interfaces up to 480 Mbps without requiring layout compensation. |
| MSL Level 1 reflow compatibility | Rated for 260 °C/10 s soldering profile-supports standard lead-free assembly without moisture-related popcorning risk. |
| RoHS/WEEE compliant & green compound | Meets EU directives and environmental standards; matte tin (e3) finish eliminates lead and avoids whisker formation risks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 0.5-pF typical capacitance, 12-V VRWM, 4-A IPPM; SOT-5X3 package. | Optimized for ultra-high-speed interfaces (USB 3.0+, PCIe); insufficient for dual-line 15-V rail protection. | Select when lowest possible capacitance is critical and only one line requires protection at lower voltage. |
| SP1003-01UTG | Three-line ESD array, 12-V VRWM, 12-A IPPM, 15-pF CD; SOT-143 package. | Supports triple-line protection (e.g., USB ID/VBUS/D−); higher surge rating but larger footprint and fixed 12-V standoff. | Choose for multi-line systems needing higher surge margin and tighter capacitance control, accepting larger board area. |
Compared with TPD2E001DRYR and SP1003-01UTG, GSOT15C-HT3-GS08 uniquely balances 15-V standoff, dual-line BiAs/BiSy flexibility, and 90–120 pF capacitance in a 1.6 × 1.2 mm footprint-making it optimal for compact, dual-signal interfaces where voltage margin and layout density are jointly constrained.

FAQ
What is the primary protection mode of GSOT15C-HT3-GS08?
The GSOT15C-HT3-GS08 operates primarily in BiAs (Bidirectional Asymmetrical) mode, where Pin 1 and Pin 2 connect to separate signal lines and Pin 3 is grounded-enabling independent clamping of each line to ground with distinct forward/reverse voltage thresholds. This mode is ideal for differential or parallel data buses like USB D+/D−.
Can GSOT15C-HT3-GS08 be used for single-line symmetrical protection?
Yes, GSOT15C-HT3-GS08 supports BiSy (Bidirectional Symmetrical) mode: connect Pin 1 to the signal line, Pin 2 to ground (or vice versa), and leave Pin 3 unconnected. In this configuration, it provides matched positive/negative clamping-suitable for VBUS overvoltage protection or single-ended analog lines requiring balanced transient suppression.
What is the maximum clamping voltage of GSOT15C-HT3-GS08 under full-rated surge current?
In BiAs mode, the GSOT15C-HT3-GS08 exhibits a maximum reverse clamping voltage (VC) of 24.8 V at its rated 8 A peak pulse current (IPPM). In BiSy mode, VC reaches 26.6 V at the same 8 A-both values measured per IEC 61000-4-5 8/20 µs waveform, ensuring downstream ICs remain within safe voltage limits.
How does the capacitance of GSOT15C-HT3-GS08 vary with applied voltage?
The GSOT15C-HT3-GS08 has a typical capacitance of 90–120 pF at 0 V bias and drops to 35 pF at 7.5 V reverse bias (VR = 7.5 V, f = 1 MHz). This voltage-dependent capacitance minimizes signal distortion on active data lines while maintaining strong ESD suppression at DC and low-frequency transients.
Is GSOT15C-HT3-GS08 compatible with lead-free reflow processes?
Yes, GSOT15C-HT3-GS08 is fully compatible with lead-free reflow soldering: it carries MSL Level 1 rating per J-STD-020 and is qualified for 260 °C peak temperature for 10 seconds at terminals-supporting standard Pb-free assembly without preconditioning or special handling.
