Product details
Overview
SMCG130A-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for high-energy surge protection in automotive and industrial power rails. It features a 130 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), 209 V maximum clamping voltage (VC) at 7.2 A IPPM, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the SMCG130A-E3/57T datasheet, SMCG130A-E3/57T pinout, SMCG130A-E3/57T application, or SMCG130A-E3/57T equivalent, this device is selected for robust overvoltage protection where fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive transients are critical - especially in 12 V/24 V DC systems with IFSM up to 200 A.
Technical Context
The SMCG130A-E3/57T uses a glass-passivated silicon junction optimized for unidirectional transient suppression with a 10/1000 µs waveform compliance. Its breakdown voltage (VBR) is specified at 144–159 V (IT = 1 mA), ensuring precise triggering above system operating voltage while maintaining low leakage (<1.0 µA at VWM = 130 V).
Thermally, it delivers RθJA = 75 °C/W on standard 8.0 mm × 8.0 mm copper pads and supports continuous operation from –55 °C to +150 °C junction temperature. The matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse working voltage before clamping begins; sets upper limit for protected circuit's normal operating range. |
| VBR (min/max) | 144 V / 159 V at IT = 1 mA - Confirmed breakdown threshold ensures reliable turn-on margin above VWM without premature conduction. |
| VC @ IPPM | 209 V at 7.2 A - Clamping voltage during 10/1000 µs surge defines worst-case voltage seen by downstream ICs or MOSFETs. |
| PPPM | 1500 W - Peak pulse power handling capacity determines survivability against ISO 7637-2 Pulse 5a/b or IEC 61000-4-5 surges. |
| IFSM | 200 A - Non-repetitive forward surge rating validates capability to absorb inductive kickback in relay or solenoid drive circuits. |
| TJ max. | +150 °C - Maximum junction temperature enables use in high-ambient environments such as automotive engine control units. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC-Q101 Rev D. |
Pinout & Package
Package: SMCG (DO-215AB) - Surface-mount gull-wing leaded package with cathode band marking; 0.310" × 0.400" footprint (7.87 mm × 10.16 mm); meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or low-side return path in unidirectional TVS configuration. | Provides low-impedance discharge path to reference plane during positive transients; polarity must match PCB silkscreen band. |
| Cathode | Current exit terminal in forward bias; marked with band; connects to protected line (e.g., battery rail or signal input). | Defines directionality: clamps positive transients on cathode-connected lines to anode (ground); reverse connection disables protection. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and improved humidity resistance versus epoxy-passivated alternatives. |
| Low incremental surge resistance | Minimizes VC rise under high-current transients, preserving margin between clamping voltage and IC absolute maximum ratings. |
| MSL Level 1 (260 °C peak) | Enables compatibility with standard lead-free reflow profiles without preconditioning or special handling. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body electronics where failure modes must meet stringent stress-test requirements. |
| Matte tin plating | Guarantees solder joint integrity per J-STD-002 and eliminates whisker risk per JESD201 Class 2 for long-term reliability. |

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 VC (209 V), but lower PPPM (400 W) and smaller SMA (DO-214AC) package. | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5 or high-IFSM motor drives. | Select when board space is constrained and surge energy does not exceed 400 W. |
| SMCJ130A-E3/57T | Identical VWM (130 V), VC (209 V), and PPPM (1500 W), but in larger SMC (DO-214AB) package with higher thermal mass. | Better sustained power dissipation in high-temperature enclosures; requires larger PCB area and different pad layout. | Choose when thermal derating below 75 °C/W is needed or legacy SMC footprint is retained. |
Compared with SMAJ130A-E3/57T, SMCG130A-E3/57T delivers 3.75× higher surge power handling in a compact DO-215AB outline; versus SMCJ130A-E3/57T, it achieves equivalent electrical performance with ~25% smaller footprint and tighter pitch tolerance for dense automotive layouts.

FAQ
What is the clamping voltage of the SMCG130A-E3/57T under a 10/1000 µs surge?
The SMCG130A-E3/57T has a maximum clamping voltage (VC) of 209 V at 7.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCG130A-E3/57T maintains this clamping performance across its full operating temperature range.
Is the SMCG130A-E3/57T suitable for bidirectional transient protection?
No - the SMCG130A-E3/57T is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only during positive transients on the cathode-connected line and blocks reverse voltage. For bidirectional protection at 130 V, the correct part is SMCG130CA-E3/57T, which has symmetrical breakdown in both directions and no polarity marking.
Does the SMCG130A-E3/57T meet automotive qualification standards?
Yes - the SMCG130A-E3/57T carries the HE3 suffix variant designation in Vishay's ordering matrix and is explicitly AEC-Q101 qualified per Revision 09-Jan-2024 documentation. This includes validation for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per AEC-Q101 Rev D, making it suitable for under-hood and powertrain applications.
What is the thermal resistance of the SMCG130A-E3/57T on standard PCB pads?
The SMCG130A-E3/57T 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, as defined in the Vishay datasheet. This value assumes FR-4 substrate and natural convection; actual RθJA will improve with internal copper planes or forced airflow. The SMCG130A-E3/57T also exhibits RθJL = 15 °C/W to the lead.
Can the SMCG130A-E3/57T replace the older SMA6J130A in an existing design?
No direct replacement - while both have VWM = 130 V, the SMA6J130A is a 600 W device in SMA package with higher VC (230 V) and no AEC-Q101 qualification. The SMCG130A-E3/57T offers 1500 W PPPM, lower VC (209 V), DO-215AB footprint, and automotive qualification, but requires PCB layout revision due to different pad dimensions and gull-wing lead geometry.
