Product details
Overview
SMCG130A-E3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, featuring a 130 V standoff voltage (VWM), 144–159 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamping voltage of 209 V at 7.2 A IPPM. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in automotive and industrial power electronics.
For engineers reviewing the SMCG130A-E3/9AT datasheet, SMCG130A-E3/9AT pinout, SMCG130A-E3/9AT application, or SMCG130A-E3/9AT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W surge capability with 10/1000 µs waveform, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector with glass-passivated junction and low incremental surge resistance. Its unidirectional configuration provides cathode-band polarity marking and forward conduction only during reverse-transient events, enabling precise integration into DC power rails and signal paths where polarity-sensitive protection is required.
The device meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports 200 A IFSM (8.3 ms half-sine), and delivers stable clamping performance across -55 °C to +150 °C junction temperature range. Its DO-215AB package enables high-power density while maintaining compatibility with standard surface-mount assembly processes.

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 | Lower surge capacity limits use to consumer-grade or non-automotive systems | Select when cost sensitivity outweighs need for 1500 W surge headroom and AEC-Q101 compliance |
| SMCJ130A-E3/9AT | Same VWM (130 V), higher PPPM (1500 W), but larger SMC (DO-214AB) package and no AEC-Q101 qualification | Lacks automotive qualification; suitable for industrial but not safety-critical vehicle subsystems | Choose when board space allows larger footprint and automotive qualification is not mandated |
Compared with SMAJ130A-E3/57T and SMCJ130A-E3/9AT, SMCG130A-E3/9AT uniquely combines 1500 W surge capability, AEC-Q101 qualification, and compact DO-215AB packaging-making it optimal for space-constrained automotive modules requiring certified reliability.

FAQ
What is the clamping voltage of SMCG130A-E3/9AT at its rated peak pulse current?
The SMCG130A-E3/9AT has a maximum clamping voltage (VC) of 209 V at its specified peak pulse current (IPPM) of 7.2 A, measured using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full 1500 W transient event and is confirmed in the Electrical Characteristics table on page 2 of the Vishay document 88457.
Is SMCG130A-E3/9AT qualified for automotive applications?
Yes, SMCG130A-E3/9AT is AEC-Q101 qualified, as explicitly stated in the Mechanical Data section and confirmed in the Ratings and Characteristics Curves footnote (1) of Vishay document 88457. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge, validating its use in automotive powertrain and body electronics.
What does the "E3/9AT" suffix indicate in SMCG130A-E3/9AT?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads, while "9AT" specifies the packaging format: 13-inch diameter plastic tape and reel containing 3500 units. This ordering code is documented in the Ordering Information table on page 3 of Vishay document 88457 and confirms compliance with J-STD-002 solderability standards.
How does the SMCG (DO-215AB) package compare thermally to SMA or SMC packages?
The SMCG (DO-215AB) package of SMCG130A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W on the recommended 8.0 mm × 8.0 mm copper pad layout. This is lower than SMA (DO-214AC) packages (~100–120 °C/W) and comparable to SMC (DO-214AB), enabling higher sustained power dissipation in compact layouts without additional heatsinking.
Can SMCG130A-E3/9AT be used in bidirectional configurations?
No, SMCG130A-E3/9AT is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and confirmed by its cathode-band marking and forward voltage specification (VF = 3.5 V at 100 A). Bidirectional variants such as SMCG130CA exist in the same family but are distinct orderable parts with symmetrical breakdown in both directions.
