Product details
Overview
SMCG16A-E3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR) at 1 mA, 26.0 V clamping voltage (VC) at 57.7 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with a 10/1000 µs waveform - deployed in automotive power line and sensor interface protection.
For engineers reviewing the SMCG16A-E3/9AT datasheet, SMCG16A-E3/9AT pinout, SMCG16A-E3/9AT application, or SMCG16A-E3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), RoHS-compliant E3 suffix, and reel packaging details (3500 pcs per 13" reel) to support design-in and supply chain decisions.
Technical Context
The SMCG16A-E3/9AT operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to clamp transients induced by inductive load switching or ESD events. Its unidirectional polarity (cathode-banded) enables integration into DC power rails and signal lines where reverse conduction must be blocked.
Rated for -55 °C to +150 °C operating junction temperature and qualified to AEC-Q101, it supports automotive-grade reliability under thermal cycling and mechanical stress. The DO-215AB package provides surface-mount compatibility with J-STD-002 solderability and meets UL 94 V-0 flammability requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/57T | Same VWM (16 V), lower PPPM (400 W), SMA (DO-214AC) package, RθJA = 110 °C/W | Lower power handling; suited for consumer-grade, non-automotive designs with less stringent surge requirements | Select when cost sensitivity outweighs automotive qualification and 1500 W surge margin |
| SMCJ16A-E3/9AT | Same VWM (16 V), identical PPPM (1500 W), larger SMC (DO-214AB) package, RθJA = 50 °C/W, same AEC-Q101 | Higher thermal performance but requires more PCB area; preferred for high-reliability industrial power supplies | Choose when board space allows and lower junction-to-ambient thermal resistance is critical for sustained surge duty |
Compared with SMAJ16A-E3/57T and SMCJ16A-E3/9AT, the SMCG16A-E3/9AT delivers identical surge capability in a smaller DO-215AB footprint with AEC-Q101 qualification - making it optimal for space-constrained automotive modules where thermal management relies on pad layout rather than package size.

FAQ
What is the clamping voltage of SMCG16A-E3/9AT and how is it measured?
The SMCG16A-E3/9AT has a maximum clamping voltage (VC) of 26.0 V, measured at a peak pulse current (IPPM) of 57.7 A using a standardized 10/1000 µs waveform. This value reflects the actual voltage seen by protected circuitry during surge events and is guaranteed across the operating temperature range. The clamping behavior is defined by its silicon avalanche structure and validated per ANSI/IEEE C62.35.
Is SMCG16A-E3/9AT suitable for automotive applications?
Yes, SMCG16A-E3/9AT is AEC-Q101 qualified and rated for -55 °C to +150 °C junction temperature, making it suitable for under-hood and body-control module applications. Its glass-passivated junction, MSL Level 1 rating, and UL 94 V-0 package meet automotive manufacturing and reliability requirements. The E3 suffix confirms RoHS compliance for automotive supply chains.
What does the "-E3/9AT" suffix mean in SMCG16A-E3/9AT?
The "E3" denotes RoHS-compliant, industrial-grade termination with JESD 201 Class 2 whisker resistance; "9AT" specifies packaging in a 13-inch diameter plastic tape-and-reel format containing 3500 units. This differs from "57T" (7-inch reel, 850 units) and supports high-volume SMT assembly with optimized feeder compatibility and traceability.
How does SMCG16A-E3/9AT compare to bidirectional variants like SMCG16CA?
SMCG16A-E3/9AT is unidirectional with cathode marking and blocks reverse current, while SMCG16CA is bidirectional with no polarity marking and clamps in both directions. Their VWM (16 V), VBR, and PPPM (1500 W) are identical, but SMCG16A-E3/9AT is used where DC bias must be preserved - such as on positive power rails - whereas SMCG16CA suits AC-coupled or floating signal lines.
What thermal derating applies to SMCG16A-E3/9AT above 25 °C ambient?
SMCG16A-E3/9AT follows the derating curve in Figure 2 of Vishay document 88457: power dissipation (PD) decreases linearly above TA = 25 °C, reaching zero at TJ = 150 °C. With RθJA = 75 °C/W, its usable PD drops to ~4.3 W at 75 °C ambient. Derating is based on 0.31" × 0.31" copper pads per terminal - reduced pad area increases thermal resistance and accelerates derating.
