Product details
Overview
SMCG8.0AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZorb® transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, with 8.0 V stand-off voltage (VWM), 6.40–9.83 V breakdown voltage (VBR), 13.6 V clamping voltage (VC) at 110.3 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM). It is AEC-Q101 qualified and used for protecting automotive sensor signal lines against inductive switching transients.
For engineers reviewing the SMCG8.0AHE3/57T datasheet, SMCG8.0AHE3/57T pinout, SMCG8.0AHE3/57T application, or SMCG8.0AHE3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity marking, AEC-Q101 qualification status, and compatibility with 7" tape-and-reel (57T) automated assembly.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (6.40–9.83 V at 10 mA test current), clamping transients to ≤13.6 V at 110.3 A. Its low incremental surge resistance and fast response time enable effective protection of downstream ICs and MOSFETs.
Designed for surface-mount use on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power handling with thermal resistance RθJA = 75 °C/W and junction temperature range of –55 °C to +150 °C. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.40 V / 9.83 V at 10 mA - ensures reliable turn-on across manufacturing tolerance and temperature |
| VC @ IPPM | 13.6 V at 110.3 A - limits voltage seen by protected circuit during 10/1000 µs transient |
| PPPM | 1500 W - peak transient energy absorption capability under standardized surge waveform |
| ID @ VWM | 50 µA - low leakage preserves signal integrity in high-impedance sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A-E3/52T | Same VWM (8.0 V), but SMA (DO-214AC) package; 400 W PPPM vs. 1500 W; RθJA = 110 °C/W | Limited to lower-energy transients; unsuitable for automotive load-dump where 1500 W is required | Select SMCG8.0AHE3/57T when higher surge robustness and AEC-Q101 qualification are mandatory |
| SMCJ8.0AHE3/57T | Same SMCG package and AEC-Q101 qualification, but 3000 W PPPM; VBR = 8.89–9.83 V; VC = 13.6 V at 221 A | Over-specified for 1500 W use cases; higher cost and larger PCB footprint not justified unless >2000 W needed | Choose SMCG8.0AHE3/57T for optimal balance of surge rating, size, and cost in 1500 W-class designs |
Compared with SMAJ8.0A-E3/52T and SMCJ8.0AHE3/57T, SMCG8.0AHE3/57T uniquely delivers 1500 W surge capability in an AEC-Q101-qualified DO-215AB package-making it the precise fit for automotive and industrial applications requiring validated reliability without over-engineering.

FAQ
What is the clamping voltage of SMCG8.0AHE3/57T and how is it measured?
The clamping voltage (VC) of SMCG8.0AHE3/57T is 13.6 V, measured at 110.3 A peak pulse current (IPPM) using the standardized 10/1000 µs double-exponential surge waveform. This value reflects the maximum voltage imposed on the protected circuit during worst-case transient conditions, and is guaranteed across the full operating temperature range per Vishay's datasheet Figure 4.
Is SMCG8.0AHE3/57T suitable for automotive applications?
Yes, SMCG8.0AHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 moisture sensitivity, and operation up to +150 °C junction temperature-meets requirements for engine control units, body electronics, and ADAS sensor interfaces subject to ISO 7637-2 and ISO 16750-2 stress tests.
What does the "HE3/57T" suffix mean in SMCG8.0AHE3/57T?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads; "57T" specifies packaging in 7-inch diameter plastic tape-and-reel containing 850 units. This format supports high-speed pick-and-place assembly and ensures traceability and environmental compliance for automotive and industrial production lines.
How does SMCG8.0AHE3/57T differ from bidirectional TVS diodes like SMCG8.0CA?
SMCG8.0AHE3/57T is unidirectional and features a cathode band for polarity-sensitive placement, whereas SMCG8.0CA is bidirectional with no polarity marking and symmetric clamping in both directions. The unidirectional version offers lower leakage (<50 µA at 8.0 V) and is preferred for DC-biased signal lines; bidirectional types suit AC-coupled or floating interfaces.
What PCB pad layout is recommended for optimal thermal and surge performance of SMCG8.0AHE3/57T?
Vishay specifies mounting SMCG8.0AHE3/57T on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W peak pulse power and thermal resistance of 75 °C/W. Reduced pad area degrades both surge handling and steady-state power dissipation, potentially causing premature failure under repeated transients.
