Product details
Overview
GL15-HT3-GS08 from Vishay Semiconductors is a low-capacitance ESD protection diode array designed for bidirectional transient suppression on high-speed data lines. It features a 15 V working peak reverse voltage (VRWM), 16.7 V minimum breakdown voltage (VBR), 1 μA maximum reverse leakage at VRWM, 24 V clamping voltage at 1 A peak pulse current (VC), and 10 pF junction capacitance at 0 V - enabling USB 2.0 and LAN port protection in portable electronics.
For engineers reviewing the GL15-HT3-GS08 datasheet, GL15-HT3-GS08 pinout, GL15-HT3-GS08 application, or GL15-HT3-GS08 equivalent, key selection criteria include IEC 61000-4-2 ESD robustness (>25 kV air), low 10 pF signal-line loading, 300 W 8/20 μs peak pulse power handling, and LLP75-3B package compatibility with space-constrained PCB layouts.
Technical Context
This device implements a monolithic dual-diode configuration in a single LLP75-3B package, with Pin 1 and Pin 2 forming the protected differential pair and Pin 3 internally connected to case ground (NC terminal). Its silicon avalanche structure delivers fast response (<1 ns) to ESD transients while maintaining low dynamic impedance during clamping.
The GL15-HT3-GS08 operates across –55 °C to +125 °C junction temperature and supports reflow soldering up to 260 °C for 10 seconds. Its 5.2 mg mass and UL 94 V-0 molding compound meet stringent reliability requirements for handheld and industrial communication interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z15T1G (ON Semiconductor) | Same VRWM (15 V), but higher Cj = 25 pF; SOD-523 package (1.3 × 0.8 mm) | Less suitable for >100 Mbps interfaces due to doubled capacitance; better for lower-speed audio or GPIO | Select when board space is tighter than signal bandwidth requirements |
| TPD2E001DRYR (Texas Instruments) | Lower VRWM = 5.5 V; dual-channel with 12 pF Cj; X2SON package (1.0 × 0.6 mm) | Not suitable for 15 V-biased lines; intended for 3.3 V/5 V digital I/O, not analog or high-voltage data paths | Choose only for low-voltage microcontroller I/O protection, not for USB or Ethernet |
Compared with ESD5Z15T1G and TPD2E001DRYR, the GL15-HT3-GS08 uniquely balances 15 V operating margin, 10 pF capacitance, and 33 A surge capability in a thermally enhanced LLP75-3B package - making it optimal for USB 2.0, industrial Ethernet, and automotive display links where both voltage headroom and signal fidelity are critical.

FAQ
What is the maximum clamping voltage of the GL15-HT3-GS08 at 5 A peak pulse current?
The GL15-HT3-GS08 has a maximum clamping voltage (VC) of 33 V at 5 A peak pulse current under an 8/20 μs waveform. This value is specified in the Electrical Characteristics table of Vishay Document Number 85823 Rev. 1.7 and defines the upper voltage limit imposed on protected lines during high-energy transients, ensuring downstream ICs remain within safe operating limits. The GL15-HT3-GS08 maintains this clamping performance across its full operating temperature range.
Is the GL15-HT3-GS08 suitable for protecting USB 2.0 differential data lines?
Yes, the GL15-HT3-GS08 is explicitly designed for USB 2.0 port protection. Its 10 pF junction capacitance minimizes signal integrity impact on 480 Mbps data rates, while its bidirectional configuration allows direct placement across D+ and D− lines. The 15 V VRWM provides sufficient margin above USB's 3.3 V signaling levels, and the 24 V clamping voltage at 1 A ensures robust protection without violating PHY IC absolute maximum ratings. The GL15-HT3-GS08 appears in Vishay's application guidance for high-speed data interface protection.
What does "Pin 3 NC" mean for the GL15-HT3-GS08?
"Pin 3 NC" means Pin 3 is a No-Connection terminal - it is internally isolated and not electrically bonded to any die structure. Per Vishay's mechanical drawing and datasheet, Pin 3 must not be soldered to ground or any other net on the PCB. This design eliminates unintended parasitic paths and simplifies layout, especially in high-frequency applications where stray capacitance or ground loops could degrade ESD performance. The GL15-HT3-GS08 relies solely on Pins 1 and 2 for functional protection.
Does the GL15-HT3-GS08 meet IEC 61000-4-5 lightning surge requirements?
Yes, the GL15-HT3-GS08 supports IEC 61000-4-5 compliance through its 33 A peak pulse current rating (IPPM) under an 8/20 μs waveform and 300 W peak pulse power (PPK) capability. While the datasheet references IEC 61000-4-5 indirectly via IPPM and PPK metrics rather than full system-level test results, these parameters are the standard basis for evaluating component-level lightning surge withstand in telecom and industrial equipment designs. The GL15-HT3-GS08 is routinely applied in such contexts per Vishay's application notes.
What is the thermal resistance (RθJA) of the GL15-HT3-GS08 in its LLP75-3B package?
The datasheet for GL15-HT3-GS08 does not specify junction-to-ambient thermal resistance (RθJA) as a standalone parameter. However, the device is rated for continuous operation from –55 °C to +125 °C junction temperature and qualified for high-temperature soldering (260 °C/10 sec), indicating robust thermal performance in the LLP75-3B package. For thermal design, users should rely on the absolute maximum ratings and derating curves provided in Vishay Document Number 85823. The GL15-HT3-GS08 is not intended for sustained power dissipation; its thermal design centers on transient energy absorption.
