Product details
Overview
GL05-HT3-GS08 from Vishay Semiconductors is a low-capacitance ESD protection diode designed for high-speed data line protection. It features 5 V working peak reverse voltage (VRWM), 6 V minimum breakdown voltage (VBR), 20 μA maximum reverse leakage (IR), 9.8 V clamping voltage at 1 A (VC), and 5 pF junction capacitance - enabling robust IEC 61000-4-2 ESD protection in USB 2.0 and cellular handset interfaces.
For engineers reviewing the GL05-HT3-GS08 datasheet, GL05-HT3-GS08 pinout, GL05-HT3-GS08 application, or GL05-HT3-GS08 equivalent, this device delivers validated 15 kV air/8 kV contact ESD immunity, ultra-low 5 pF capacitance for signal integrity preservation, and LLP75-3B package compatibility with high-density portable PCB layouts.
Technical Context
The GL05-HT3-GS08 is a unidirectional transient voltage suppression diode configured as a single-channel ESD clamp with Pin 1 anode, Pin 2 cathode, and Pin 3 NC. Its 5 V VRWM aligns with 3.3 V and 5 V logic interface rails, and its 9.8 V VC(max) at 1 A ensures safe clamping below typical IC I/O absolute maximum ratings.
Designed for IEC 61000-4-2 compliance, it sustains >25 kV ESD events and handles 300 W peak pulse power (8/20 μs). The 5 pF capacitance between Pin 1 and Pin 2 is measured at 0 V and 1 MHz, making it suitable for USB Full-Speed (12 Mbps) and other sub-480 Mbps data paths without signal degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 4-channel array, 5.5 V VRWM, 6.5 V VBR, 12 pF Cj, SOT-563 package | Higher channel count but higher capacitance; requires routing for four lines | Choose for multi-line protection where board area allows larger package and higher Cj is acceptable |
| ESD5Z5.0T1G | Single-channel, 5 V VRWM, 6.2 V VBR, 18 pF Cj, SOD-523 package | Same VRWM but 3.6× higher capacitance; less suitable for >10 Mbps data rates | Choose only for cost-sensitive, low-speed GPIO or button-line protection where 5 pF is not required |
Compared with TPD4E05U06DQAR and ESD5Z5.0T1G, the GL05-HT3-GS08 uniquely balances ultra-low 5 pF capacitance, industry-leading >25 kV ESD rating, and compact LLP75-3B footprint - making it optimal for space-constrained, high-speed USB and mobile data line protection where signal fidelity and reliability are co-prioritized.

FAQ
What is the primary function of the GL05-HT3-GS08?
The GL05-HT3-GS08 is a unidirectional ESD protection diode designed to safeguard high-speed data lines from electrostatic discharge. Its core function is to clamp transient voltages-such as those from human-body-model ESD events-to safe levels (≤9.8 V at 1 A) while adding minimal capacitance (5 pF) that preserves signal integrity. This makes the GL05-HT3-GS08 especially effective on USB 2.0, MIPI, and other sub-480 Mbps interfaces.
Is the GL05-HT3-GS08 RoHS compliant and lead-free?
Yes, the GL05-HT3-GS08 is fully RoHS 2002/95/EC compliant and lead (Pb)-free. It uses an e3 matte tin terminal finish and meets both the Restriction of Hazardous Substances Directive and the Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC. The molding compound also carries UL 94 V-0 flammability certification, confirming safety in end-user devices.
What does the "GS08" suffix indicate in GL05-HT3-GS08?
The "GS08" suffix denotes tape-and-reel packaging per the manufacturer's ordering code convention: "GS" indicates green (halogen-free, RoHS-compliant) packaging, and "08" specifies 8 mm tape width with 3,000 units per reel. This format is optimized for automated SMT placement and matches the LLP75-3B package dimensions and pitch requirements.
Can GL05-HT3-GS08 be used for bidirectional signal lines like USB D+ and D−?
Although the GL05-HT3-GS08 is unidirectional (anode-to-cathode), it can protect bidirectional data lines such as USB D+ and D− when placed with Pin 1 toward the connector and Pin 2 grounded - leveraging its symmetrical clamping behavior under positive transients and inherent reverse-blocking capability. Its 5 V VRWM and 9.8 V VC ensure safe operation across full USB 2.0 differential signaling swings without forward conduction during normal operation.
What is the thermal rating and mounting guidance for GL05-HT3-GS08?
The GL05-HT3-GS08 supports operation from –55 °C to +125 °C junction temperature and is qualified for high-temperature reflow with 260 °C/10 sec. at terminals. Its LLP75-3B package requires standard leadless component stencil design (0.15 mm thickness, 0.3 mm aperture) and nitrogen-reflow profile per IPC-J-STD-020. No thermal pad or heatsink is needed due to its transient-only power dissipation profile.
