Product details
Overview
GMF05C-GS08 from Vishay Semiconductors is an ESD protection diode array in SOT-363 package, rated for 5 V reverse stand-off voltage, 12 A peak pulse current (8/20 μs), and 200 W peak pulse power, providing bidirectional protection for four I/O lines or unidirectional protection for five lines in portable electronics.
For engineers reviewing the GMF05C-GS08 datasheet, GMF05C-GS08 pinout, GMF05C-GS08 application, or GMF05C-GS08 equivalent, key selection criteria include clamping voltage at 12.5 V (IPP = 12 A), junction capacitance of 150 pF at 0 V/1 MHz, low leakage (≤1 μA at 5 V), and compliance with IEC 61000-4-2 (15 kV air, 8 kV contact) and IEC 61000-4-5 (12 A lightning).
Technical Context
This device integrates six silicon avalanche diodes in a single SOT-363 package to deliver transient suppression across multiple signal paths. It supports both bidirectional (4-line) and unidirectional (5-line) configurations, with a 6 V breakdown voltage (It = 1 mA) and 9.5 V clamping voltage at 1 A pulse.
Thermal operation spans −55 °C to +125 °C junction temperature, with storage up to +150 °C. The 150 pF junction capacitance enables use on high-speed data lines such as USB 1.1 and audio interfaces without signal integrity degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G (ON Semiconductor) | Single-channel SOD-523, 5.0 V VRWM, 12.5 V VC @ 1 A, 350 pF | Requires six discrete devices for 5-line unidirectional protection vs. single GMF05C-GS08 | Prefer GMF05C-GS08 when board space and assembly cost are constrained |
| TPD2E001DRSR (Texas Instruments) | 2-channel SOT-563, 5.5 V VRWM, 14 V VC @ 1 A, 12 pF typical | Lower capacitance but only two channels; requires three units for full 5-line coverage | Choose TPD2E001DRSR only if <20 pF capacitance is mandatory for >480 Mbps interfaces |
Compared with ESD5Z5.0T1G and TPD2E001DRSR, GMF05C-GS08 delivers integrated 5-line unidirectional or 4-line bidirectional protection in one SOT-363 device, balancing capacitance (150 pF), clamping performance (12.5 V), and layout efficiency-making it optimal for space-constrained portable designs where moderate-speed signal integrity is required.

FAQ
What is the maximum clamping voltage of GMF05C-GS08 under IEC 61000-4-5 surge conditions?
The GMF05C-GS08 exhibits a clamping voltage of 12.5 V when subjected to a 12 A peak pulse current with an 8/20 μs waveform-matching the IEC 61000-4-5 Level 3 lightning surge test condition. This value is measured across all protected channels simultaneously and ensures downstream ICs rated for ≥13.5 V absolute maximum survive the event without damage. GMF05C-GS08 maintains this performance across its full operating temperature range.
Can GMF05C-GS08 be used for bidirectional protection of USB D+ and D− lines?
Yes, GMF05C-GS08 supports bidirectional protection of four I/O lines, making it suitable for USB 1.1 D+/D− pair protection when configured with pins 1–2 and 3–2 forming two symmetrical channels. Its 150 pF junction capacitance preserves signal integrity at 12 Mbps, and the 9.5 V clamping voltage at 1 A ensures safe operation during ESD events. GMF05C-GS08 does not support differential-mode clamping beyond its specified channel pairing.
What is the leakage current specification for GMF05C-GS08 at its rated reverse stand-off voltage?
GMF05C-GS08 specifies a maximum reverse leakage current of 1 μA when biased at its 5 V reverse stand-off voltage (VRWM), measured at 25 °C ambient. This ultra-low leakage minimizes battery drain in always-on portable circuits such as keypad scanners and SIM card interfaces. GMF05C-GS08 maintains ≤5 μA leakage across its full −55 °C to +125 °C operating junction temperature range per Vishay's characterization data.
Is GMF05C-GS08 compatible with lead-free reflow soldering processes?
Yes, GMF05C-GS08 is qualified for lead-free reflow soldering with a maximum terminal temperature tolerance of 260 °C for 10 seconds, conforming to J-STD-020 moisture sensitivity level (MSL) requirements. Its SOT-363 package uses matte tin plating and Pb-free terminations, fully compliant with RoHS 2002/95/EC. GMF05C-GS08 has been verified for compatibility with standard SnAgCu (SAC305) reflow profiles without delamination or parametric shift.
Does GMF05C-GS08 provide protection for both data lines and power rails?
No, GMF05C-GS08 is designed exclusively for signal-line ESD protection-not power rail transient suppression. Its 5 V VRWM and 6 V VBR ratings, along with 12.5 V clamping, are optimized for logic-level I/O interfaces (e.g., GPIO, USB, audio). It lacks the thermal mass and energy handling needed for power rail applications. For VBUS or battery line protection, dedicated TVS arrays like SM712 or SMAJ5.0A are recommended instead of GMF05C-GS08.
