Product details
Overview
SMCG130AHE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection with 1500 W peak pulse power (10/1000 µs), 130 V stand-off voltage (VWM), and clamping voltage of 209 V at 7.2 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive power lines and industrial sensor interfaces against inductive switching transients.
For engineers reviewing the SMCG130AHE3/9AT datasheet, SMCG130AHE3/9AT pinout, SMCG130AHE3/9AT application, or SMCG130AHE3/9AT equivalent, this page delivers verified electrical specs, polarity marking guidance, thermal resistance data, junction temperature limits, and direct alternatives for automotive-grade circuit protection design.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, triggering when reverse voltage exceeds its 144–159 V breakdown range (VBR at 1 mA). Its low incremental surge resistance and fast response time enable effective suppression of ESD and lightning-induced surges per IEC 61000-4-2/4-5.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it features glass-passivated junction, matte tin-plated leads compliant with J-STD-002, and meets MSL Level 1 (260 °C reflow peak). Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 144 V / 159 V at 1 mA - guaranteed breakdown threshold defining turn-on precision |
| VC @ IPPM | 209 V at 7.2 A - clamped voltage during 10/1000 µs surge, limiting stress on downstream ICs |
| PPPM | 1500 W - peak surge energy handling capacity under standardized waveform |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance indicating required PCB copper area for thermal management |
| AEC-Q101 | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount gull-wing leaded case with cathode band marking; dimensions 7.87 mm × 9.64 mm × 2.41 mm (L × W × H); UL 94 V-0 molding compound; RoHS-compliant, AEC-Q101 qualified (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected line ground or low-side reference | For unidirectional operation, anode ties to system ground; polarity must match PCB silkscreen band marking |
| Cathode | Current exit terminal in forward bias; marked by band on package body | Connected to the line being protected (e.g., 12 V battery rail); clamps transients toward ground when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| 1500 W peak pulse power | Withstands ISO 7637-2 Pulse 1/2a/5a surges without degradation in automotive 12 V systems |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| MSL Level 1 rating | Supports single-reflow assembly at 260 °C peak without popcorn or delamination risk |
| Low RθJL (15 °C/W) | Enables efficient heat transfer to PCB leads, critical for repeated surge events in industrial controls |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails in engine control modules from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and ground, clamping surges above 130 V. Use Value: Limits voltage seen by MCU power inputs to ≤209 V during 1500 W pulses, preventing latch-up or damage. |
Use Scenario: Shielding analog outputs of pressure sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Parallel-connected TVS on 4–20 mA loop output lines to absorb field-induced spikes. Use Value: Maintains signal integrity by clamping transients within 1 ns, preserving sub-1% accuracy of sensor readings. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drivers |
Use Scenario: Safeguarding PoE-powered Ethernet switches against induced surges on 48 V DC input lines. IC Role / Device Role / Timing Role: Standoff-rated TVS on primary DC input, triggered only during overvoltage events.

Use Scenario: Protecting gate drivers in washing machine inverter boards from back-EMF spikes during motor commutation. IC Role / Device Role / Timing Role: TVS across half-bridge MOSFET source-drain paths to clamp inductive kickback. Use Value: Clamps voltage to 209 V before MOSFET avalanche, eliminating need for snubbers and reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/57T | Same VWM (130 V) and PPPM (400 W), but lower power rating and SMA (DO-214AC) package | Limited to lower-energy surges; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 1500 W surge margin |
| SMCJ130AHE3/9AT | Same VWM (130 V), higher PPPM (1500 W), identical AEC-Q101 qualification, but SMC (DO-214AB) package | Requires larger PCB footprint (7.11 mm × 6.22 mm vs. SMCG's 7.87 mm × 9.64 mm) and different pad layout | Choose if existing SMC footprint is standardized and thermal performance via RθJA (50 °C/W) is prioritized |
Compared with SMCG130AHE3/9AT, SMAJ130A-E3/57T offers lower cost but sacrifices surge robustness and automotive qualification, while SMCJ130AHE3/9AT matches power and qualification but demands layout revision due to larger SMC package and distinct thermal pad requirements.

FAQ
What is the breakdown voltage range for SMCG130AHE3/9AT?
The SMCG130AHE3/9AT has a specified breakdown voltage (VBR) range of 144 V to 159 V at 1 mA test current, measured per ANSI/IEEE C62.35. This ensures consistent clamping onset across production lots and supports precise overvoltage threshold design in 130 V nominal systems.
Is SMCG130AHE3/9AT suitable for automotive applications?
Yes, SMCG130AHE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and validation against temperature cycling and HTRB make it appropriate for ECUs, body controllers, and ADAS power domains.
What does the HE3 suffix indicate in SMCG130AHE3/9AT?
The HE3 suffix denotes RoHS-compliant construction with AEC-Q101 qualification. Unlike base E3 (industrial grade only), HE3 confirms full automotive reliability testing and material compliance per Vishay's categorization standard (doc# 99912), including whisker resistance per JESD 201 Class 2.
How is polarity identified on the SMCG130AHE3/9AT package?
SMCG130AHE3/9AT is unidirectional and marked with a cathode band on the package body. The banded end connects to the protected line (e.g., 12 V rail), while the unmarked end is the anode, tied to ground. No marking appears on bidirectional variants, but SMCG130AHE3/9AT is strictly unidirectional per its "A" suffix and datasheet designation.
What is the thermal resistance of SMCG130AHE3/9AT under standard mounting conditions?
SMCG130AHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, and 15 °C/W junction-to-lead (RθJL). These values assume JEDEC-standard board layout and define minimum copper area needed to sustain repetitive surge duty cycles.
