Product details
Overview
SMCG16AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, with a standoff voltage of 16 V, breakdown voltage range 17.8–19.7 V at 1.0 mA, clamping voltage of 26.0 V at 57.7 A (10/1000 µs), peak pulse power rating of 1500 W, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG16AHE3/57T datasheet, SMCG16AHE3/57T pinout, SMCG16AHE3/57T application, or SMCG16AHE3/57T equivalent, this device is selected for robust overvoltage protection on power rails and signal lines where high surge immunity, low clamping ratio, and automotive-grade reliability are required.
Technical Context
The SMCG16AHE3/57T operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its specified breakdown range (17.8–19.7 V). It delivers precise clamping at 26.0 V under 57.7 A peak pulse current (10/1000 µs), achieving a clamping ratio of ~1.46 relative to VWM.
Its glass-passivated junction ensures stable leakage performance (<1.0 µA at 16 V), while the DO-215AB package supports automated placement 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), enabling reliable operation up to TJ = +150 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/57T | Same VWM (16 V), but lower PPPM (400 W) and higher VC (33.0 V at 12.3 A); SMA (DO-214AC) package, smaller thermal mass | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy transients in space-constrained consumer designs | Select only if board area is constrained and surge threat level is ≤Level 2 |
| SMCJ16AHE3/57T | Same VWM (16 V), identical DO-215AB package, but higher PPPM (3000 W) and higher VC (30.0 V at 100 A) | Overqualified for 1500 W requirements; adds cost and board area without benefit unless future-proofing for higher threats | Prefer SMCG16AHE3/57T for optimal balance of surge rating, clamping performance, and cost in automotive and industrial 12 V systems |
Compared with SMAJ16A-E3/57T and SMCJ16AHE3/57T, the SMCG16AHE3/57T delivers the exact 1500 W surge rating needed for AEC-Q101-compliant 12 V rail protection-neither under-specified nor over-engineered-while maintaining the lowest clamping voltage (26.0 V) among DO-215AB 16 V TVS options.

FAQ
What is the clamping voltage of SMCG16AHE3/57T and how is it measured?
The SMCG16AHE3/57T has a maximum clamping voltage (VC) of 26.0 V, measured at a peak pulse current (IPPM) of 57.7 A using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on the protected circuit during a surge event and is guaranteed per Vishay's datasheet revision 09-Jan-2024 (Document Number: 88457).
Is SMCG16AHE3/57T suitable for automotive applications?
Yes, SMCG16AHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 reflow compatibility, and operation up to +150 °C junction temperature-meets requirements for engine control units, body electronics, and ADAS subsystems. The HE3 suffix confirms AEC-Q101 qualification per Vishay's ordering nomenclature.
What does the "HE3/57T" suffix mean in SMCG16AHE3/57T?
In SMCG16AHE3/57T, "HE3" denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads, while "57T" specifies packaging in 7-inch-diameter plastic tape and reel containing 850 units. This format aligns with Vishay's standardized ordering code for industrial and automotive-grade surface-mount TVS diodes.
How does SMCG16AHE3/57T differ from bidirectional variants like SMCG16CA?
The SMCG16AHE3/57T is unidirectional, with polarity indicated by a cathode band and intended for DC rail protection where reverse conduction must be blocked. In contrast, SMCG16CA is bidirectional, symmetric in both directions, and used in AC-coupled or differential signal lines (e.g., RS-485, CAN). Their VWM, VBR, and VC values differ accordingly-SMCG16AHE3/57T has VWM = 16 V, while SMCG16CA has VWM = 16 V but dual-directional clamping behavior.
What PCB layout guidance applies to SMCG16AHE3/57T for optimal thermal and surge performance?
Vishay specifies mounting SMCG16AHE3/57T on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W pulse power. Minimizing trace inductance between the device and protected node is critical-short, wide traces directly to the rail and ground plane reduce overshoot. Thermal vias under pads improve heat dissipation during repetitive surges, supporting sustained operation near TJ = +150 °C.
