Product details
Overview
GSOT15C-HE3-08 from Vishay Semiconductors is a two-line bidirectional ESD protection diode in SOT-23 package, rated for ±30 kV IEC 61000-4-2 contact/air discharge, 15 V reverse stand-off voltage (VRWM), 8 A peak pulse current (IPPM), and 345 W peak pulse power (PPP) in line-to-ground mode. It serves in high-reliability data-line protection for automotive infotainment interfaces.
For engineers reviewing the GSOT15C-HE3-08 datasheet, GSOT15C-HE3-08 pinout, GSOT15C-HE3-08 application, or GSOT15C-HE3-08 equivalent, key selection criteria include clamping voltage at 8 A (24.8–28.8 V), low 90–120 pF capacitance at 0 V bias, AEC-Q101 qualification, SOT-23 footprint compatibility, and BiAs-mode dual-line transient suppression capability.
Technical Context
The GSOT15C-HE3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: pins 1 and 2 connect to protected signal lines, pin 3 to ground, enabling independent clamping of positive transients via reverse breakdown (VBR = 16.5–20 V) and negative transients via forward conduction (VF ≤ 1.8 V at 8 A). Its asymmetry delivers tighter negative clamping near ground while maintaining robust positive surge handling.
In BiSy-MODE (single-line symmetrical configuration), pin 3 is left unconnected, and pins 1–2 form a bipolar path with VRWM = 15.5 V, VBR = 17–20.7 V, and clamping voltage up to 30.6 V at 8 A - optimized for balanced differential or single-ended bus protection where polarity symmetry is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Immunity | ±30 kV contact & air discharge per IEC 61000-4-2 - meets automotive-level ESD robustness without external shielding. |
| Reverse Stand-off Voltage (VRWM) | 15 V - ensures no leakage during normal 12 V automotive system operation with margin. |
| Peak Pulse Current (IPPM) | 8 A (line-to-ground), 8 A (line-to-line) - sustains IEC 61000-4-5 8/20 μs surges in CAN/LIN/UART interfaces. |
| Clamping Voltage (VC) | 24.8–28.8 V at 8 A (line-to-ground) - limits transient overvoltage to safe levels for 24 V-tolerant receivers. |
| Capacitance (CD) | 90–120 pF at 0 V, 35 pF at 7.5 V - preserves signal integrity for <10 Mbps digital buses (e.g., LIN, SENT). |
| Operating Temperature | −55 °C to +150 °C - qualified for under-hood and powertrain environments per AEC-Q101. |
| Package | SOT-23 - standard 3-pin surface-mount footprint compatible with automated assembly and existing PCB layouts. |
Pinout & Package
SOT-23 package: 3-pin, gull-wing leads, 2.8 × 2.35 × 1.15 mm body, MSL level 1, lead-free (e3 Sn plating), UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 Anode/Cathode | Connects to first protected signal line (e.g., LIN bus line); forms one half of BiAs protection path to ground (pin 3). |
| Pin 2 | Line 2 Anode/Cathode | Connects to second protected signal line (e.g., UART TX/RX pair); forms second BiAs path to ground (pin 3). |
| Pin 3 | Ground Reference | Must be connected to system ground plane; provides common return for both ESD current paths in BiAs mode. |
Key Features
| Feature | Design Value |
|---|---|
| BiAs-MODE dual-line protection | Enables simultaneous protection of two independent data lines with asymmetric clamping - ideal for LIN, SENT, or dual-CAN FD channels sharing one device. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces with full temperature and reliability testing. |
| Low clamping voltage asymmetry | Forward clamping ≤1.8 V at 8 A keeps negative transients tightly controlled near ground, reducing risk of latch-up in CMOS receivers. |
| Space-efficient SOT-23 footprint | Replaces discrete dual-diode arrays or larger SO-8 solutions, saving >60% board area while maintaining thermal performance. |
| e3 Sn termination | Lead-free, RoHS-compliant matte tin plating ensures reliable solder joint formation and long-term intermetallic stability. |
Applications
| Automotive LIN Bus Protection | Industrial UART Interface Protection |
|---|---|
Use Scenario: Protecting LIN transceivers in door modules and seat controllers against ESD events during assembly and field operation. IC Role / Device Role / Timing Role: Two-line ESD suppressor placed directly at connector entry point, shunting transients before they reach the LIN PHY. Use Value: Prevents communication failure and component damage with 15 V VRWM matching LIN's 12 V nominal supply and 28.8 V clamping staying below receiver absolute maximum ratings. | Use Scenario: Safeguarding UART lines between PLC mainboard and remote I/O modules exposed to factory floor ESD. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor on TX/RX pairs, operating in BiAs mode with shared ground reference. Use Value: 90–120 pF capacitance avoids signal rise-time degradation at 115.2 kbps, while ±30 kV immunity exceeds IEC 61000-4-2 Level 4 requirements. |
| Automotive Sensor Signal Conditioning | Consumer Electronics Touch Interface ESD Guard |
Use Scenario: Shielding analog/digital sensor outputs (e.g., pressure, temperature) in battery management systems from handling ESD. IC Role / Device Role / Timing Role: Low-leakage (IR ≤1 μA at 15 V) clamp on sensor signal lines, preserving accuracy in high-impedance measurement paths. Use Value: 1 μA reverse leakage at VRWM ensures minimal offset error in 16-bit ADC front-ends, while 150 °C rating supports under-battery-pack placement. | Use Scenario: Adding robust ESD protection to capacitive touch controller I²C lines in smartphones and tablets. IC Role / Device Role / Timing Role: Dual-line suppressor on SDA/SCL lines using BiAs configuration to maintain low dynamic capacitance and fast response. Use Value: 35 pF capacitance at 7.5 V bias minimizes clock jitter on 400 kHz I²C, and 15 V VRWM prevents false triggering during normal 3.3 V logic operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT15C-HM3-08 | Same VRWM (15 V), identical SOT-23 package, but higher IPPM (12 A) and lower clamping (22–26 V at 8 A); green environmental status. | Preferred for next-generation designs requiring extended surge margin without layout change. | Select when higher IEC 61000-4-5 immunity or longer product lifecycle (VGSOTxxC series continues beyond Jan 2025 EOL) is required. |
| SMF15CTHE3_A/H | Single-line 15 V TVS (SOD-123FL), 12.5 A IPPM, 24.4 V VC at 8 A; not dual-line capable. | Requires two devices for dual-line protection, increasing BOM count and PCB area. | Choose only if BiAs functionality is unnecessary and discrete placement flexibility outweighs integration benefits. |
Compared with VGSOT15C-HM3-08, GSOT15C-HE3-08 offers identical pinout and electrical interface but lower surge rating and imminent end-of-life; compared with SMF15CTHE3_A/H, it delivers integrated dual-line protection in half the footprint but lacks the higher surge headroom of the newer Vishay replacement.
