Product details
Overview
GSOT36-E3-08 from Vishay Semiconductors is a single-line bidirectional asymmetrical (BiAs) ESD protection diode in SOT-23 package, rated for 36 V reverse stand-off voltage, ±30 kV IEC 61000-4-2 ESD immunity, and 3.5 A peak pulse current. It protects low-capacitance signal lines such as USB 2.0, HDMI DDC, or industrial sensor interfaces.
For engineers reviewing the GSOT36-E3-08 datasheet, GSOT36-E3-08 pinout, GSOT36-E3-08 application, or GSOT36-E3-08 equivalent, key selection criteria include its 52–65 pF capacitance at 0 V, 59–71 V clamping voltage at 3.5 A, AEC-Q101 qualification option, SOT-23 footprint compatibility, and end-of-life status with VGSOTxx migration path.
Technical Context
The GSOT36-E3-08 implements BiAs-MODE architecture: pin 1 is ground, pin 3 connects to the protected line, and clamping occurs asymmetrically-reverse breakdown at 39–47 V with high-impedance isolation below 36 V, forward conduction near 0 V during negative transients. Its design enables precise voltage thresholding without external bias.
This device operates across –40 °C to +125 °C junction temperature, meets MSL level 1 per J-STD-020, and supports reflow up to 260 °C peak. The e3 Sn plating ensures RoHS-compliant, lead-free solderability while maintaining UL 94 V-0 mold compound flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 36 V - maximum continuous operating voltage before leakage exceeds 1 μA; defines safe interface voltage range for 3.3 V/5 V/12 V/24 V systems. |
| ESD Immunity | ±30 kV contact/air discharge per IEC 61000-4-2 - exceeds Level 4 system-level ESD requirements for industrial and automotive electronics. |
| Clamping Voltage (3.5 A) | 59–71 V - limits transient overvoltage on protected line during 8/20 μs surge, preserving downstream IC integrity. |
| Capacitance (0 V, 1 MHz) | 52–65 pF - low enough for USB 2.0 (≤60 pF spec), HDMI DDC, and CAN FD data lines without signal integrity degradation. |
| Peak Pulse Current | 3.5 A per IEC 61000-4-5 - handles typical lightning-induced surges in industrial control and sensor front-ends. |
| Operating Temperature | –40 °C to +125 °C - supports under-hood automotive, factory automation, and outdoor embedded applications. |
Pinout & Package
SOT-23 package: 3-pin surface-mount, 2.8 × 2.35 × 1.15 mm body, gull-wing leads, e3 matte tin plating, MSL level 1, 260 °C max reflow peak.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground (Anode common) | Low-inductance return path for ESD current; must connect directly to system ground plane with minimal trace length. |
| Pin 2 | No connection (NC) | Internally unconnected; no PCB routing required; maintains standard SOT-23 footprint compatibility. |
| Pin 3 | Protected Line (Cathode) | Input/output node for data/signal line; clamps transients to ground via BiAs-mode bidirectional conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Asymmetrical (BiAs) Clamping | Enables precise 36 V reverse hold-off and sub-1.3 V forward clamping-ideal for mixed-polarity signal lines without external bias networks. |
| AEC-Q101 Qualified Option | Validated for automotive-grade reliability including HTOL, TC, and ESD stress-supports infotainment, body control, and ADAS sensor interfaces. |
| Low Capacitance at Operating Bias | 12 pF at 18 V reverse bias-minimizes loading on high-speed lines like I²C, SMBus, or LIN bus while maintaining robust ESD protection. |
| SOT-23 Footprint Standardization | Shares land pattern with GSOT03–GSOT36 family-enables scalable ESD protection across voltage grades without PCB redesign. |
| End-of-Life Managed Migration | Documented replacement path to VGSOTxx series-ensures continuity planning for production programs through January 2025 sunset date. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT36-E3-08 | Successor device with identical SOT-23 footprint, same 36 V VRWM, but improved 45 pF capacitance and extended lifetime beyond Jan 2025. | Drop-in replacement for new designs; requires no layout change; supports long-term supply continuity. | Select for new designs requiring post-2025 availability and tighter capacitance tolerance. |
| SMF36A-T | Unidirectional TVS with 36 V standoff, 100 W peak power, 100 pF capacitance-higher clamping (~75 V at 3.5 A) and no BiAs asymmetry. | Suitable only for DC-biased lines where polarity is fixed; not appropriate for AC-coupled or bidirectional signals. | Choose only when protecting unidirectional power rails or biased analog lines where low capacitance is secondary to cost. |
Compared with GSOT36-E3-08, VGSOT36-E3-08 offers identical electrical performance with enhanced manufacturing longevity, while SMF36A-T trades BiAs functionality and low capacitance for higher surge power handling in unidirectional applications-making GSOT36-E3-08 optimal for signal integrity–critical bidirectional interfaces.

FAQ
What is the exact pin configuration and connection method for GSOT36-E3-08?
GSOT36-E3-08 uses a 3-pin SOT-23 package with Pin 1 as ground (anode), Pin 2 as no-connect (NC), and Pin 3 as the protected line (cathode). It must be installed with Pin 1 tied directly to a low-impedance system ground plane and Pin 3 placed in series with the signal line immediately before the protected IC input. This BiAs-MODE configuration enables bidirectional clamping without external biasing.
Is GSOT36-E3-08 qualified for automotive applications?
Yes-GSOT36-E3-08 is available in an AEC-Q101 qualified variant (e.g., GSOT36-HE3-08), which undergoes stress testing for high-temperature operating life, temperature cycling, and ESD robustness per automotive standards. It is used in body control modules, door modules, and sensor interfaces where ambient temperatures reach +125 °C and ESD immunity must exceed ±30 kV.
What is the clamping behavior of GSOT36-E3-08 during positive versus negative transients?
GSOT36-E3-08 exhibits bidirectional asymmetrical (BiAs) clamping: during positive transients, it breaks down at 39–47 V and clamps to 59–71 V at 3.5 A; during negative transients, it conducts in forward bias with ≤1.3 V clamping at 3.5 A. This asymmetry allows precise hold-off on DC-biased lines while minimizing voltage overshoot on negative edges-critical for I²C, LIN, and USB signal integrity.
How does the capacitance of GSOT36-E3-08 affect high-speed signal lines?
GSOT36-E3-08 has 52–65 pF capacitance at 0 V reverse bias and drops to 12 pF at 18 V, making it suitable for USB 2.0 (max 60 pF), HDMI DDC, and 1 Mbps CAN FD lines. Its low capacitance avoids signal attenuation and timing skew, while the voltage-dependent capacitance profile ensures minimal loading during normal operation and effective clamping during transients.
What is the official end-of-life timeline and recommended migration path for GSOT36-E3-08?
Vishay declared GSOT36-E3-08 end-of-life in January 2025, with last-time buy and final shipment dates aligned to that schedule. The documented migration path is to VGSOT36-E3-08-a functionally identical, pin-compatible successor with extended availability, same 36 V VRWM, 59–71 V clamping, and reduced 45 pF capacitance. Migration requires no PCB changes and preserves all design validations.
