Product details
Overview
SMCG16CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for clamping voltage transients on signal and power lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps to ≤26.0 V at 57.7 A (10/1000 µs waveform), making it suitable for automotive sensor line protection per AEC-Q101.
For engineers reviewing the SMCG16CA-E3/57T datasheet, SMCG16CA-E3/57T pinout, SMCG16CA-E3/57T application, or SMCG16CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, MSL Level 1 reflow compatibility, 150 °C junction temperature rating, and compliance with UL 497B for telecom and industrial surge protection.
Technical Context
This device operates as a silicon avalanche diode optimized for fast transient suppression using a glass-passivated junction. Its bidirectional symmetry enables identical clamping behavior in both polarities, eliminating polarity concerns in AC-coupled or differential signal paths.
Rated for 1500 W peak pulse power under the standardized 10/1000 µs waveform, it delivers low incremental surge resistance and sub-nanosecond response time-critical for protecting sensitive MOSFET gates, microcontroller I/O, and CAN/LIN bus transceivers against ESD and load dump events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | Same VWM (16 V) and PPPM (400 W), but lower power rating and SMA package (DO-214AC) | Limited to ≤400 W surges; unsuitable for ISO 7637-2 Pulse 5a or high-energy industrial transients | Select SMAJ16CA only for cost-sensitive consumer applications with lower surge threat profiles. |
| SMCJ16CA | Same VWM (16 V) and higher PPPM (1500 W), but larger SMC (DO-214AB) package and higher thermal resistance | Requires more PCB area; RθJA = 13°C/W vs. SMCG's 75°C/W - less efficient heat dissipation in dense layouts | Choose SMCJ16CA when legacy board space allows and higher mounting pad thermal mass is available. |
Compared with SMAJ16CA and SMCJ16CA, the SMCG16CA-E3/57T delivers identical clamping performance in a smaller DO-215AB footprint with superior thermal resistance (75°C/W), enabling higher power density and compatibility with AEC-Q101 automotive requirements not met by the SMAJ series.

FAQ
What is the clamping voltage of SMCG16CA-E3/57T at its rated peak pulse current?
The SMCG16CA-E3/57T clamps to a maximum of 26.0 V when subjected to its rated peak pulse current of 57.7 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream circuitry remains within safe operating limits during surge events. The SMCG16CA-E3/57T achieves this with low incremental surge resistance, minimizing voltage overshoot beyond the specified VC.
Is SMCG16CA-E3/57T suitable for automotive applications?
Yes, SMCG16CA-E3/57T is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its 150 °C maximum junction temperature, MSL Level 1 reflow rating, and validated performance under ISO 7637-2 load dump and pulse test conditions confirm suitability. The SMCG16CA-E3/57T also carries UL 497B recognition for telecom-grade surge protection in vehicle infotainment systems.
Does SMCG16CA-E3/57T have polarity markings on the package?
No, SMCG16CA-E3/57T is a bidirectional TVS diode and carries no polarity markings - the device functions identically regardless of orientation across the protected line. Unlike unidirectional variants (e.g., SMCG16A), the CA suffix indicates symmetrical breakdown in both directions, eliminating cathode/anode identification needs. This simplifies layout and reduces assembly errors in differential or AC-coupled circuits using the SMCG16CA-E3/57T.
What is the thermal resistance of SMCG16CA-E3/57T, and how does it affect PCB layout?
The SMCG16CA-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. This relatively low RθJA enables effective self-heating management during repetitive surges. To achieve this rating, the SMCG16CA-E3/57T must be placed on minimum recommended pad layouts - undersized pads or insufficient copper area will degrade thermal performance and reduce surge endurance.
Can SMCG16CA-E3/57T replace SMCG16A in an existing design?
SMCG16CA-E3/57T cannot directly replace SMCG16A without circuit review: SMCG16A is unidirectional (cathode-marked, forward conduction), while SMCG16CA-E3/57T is bidirectional (no marking, symmetrical clamping). Substituting the SMCG16CA-E3/57T in a DC-biased line may cause unintended conduction. Use SMCG16CA-E3/57T only where bidirectional protection is required - e.g., AC signal lines, differential buses, or floating grounds - not as a drop-in replacement for SMCG16A.
