Product details
Overview
SMCG90AHE3/57T 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 90 V standoff voltage (VWM), 100–111 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps transients to ≤146 V at 10.3 A IPPM - deployed on automotive power rails, industrial sensor interfaces, and DC-DC converter inputs.
For engineers reviewing the SMCG90AHE3/57T datasheet, SMCG90AHE3/57T pinout, SMCG90AHE3/57T application, or SMCG90AHE3/57T equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with a cathode-band polarity marking, leveraging glass-passivated silicon junction technology for fast response (<1 ns) and stable clamping under repetitive surge conditions. Its thermal resistance (RθJA = 75 °C/W) and RθJL = 15 °C/W support reliable operation up to 150 °C junction temperature when mounted per recommended pad layout.
The device complies with ANSI/IEEE C62.35 for surge testing and meets J-STD-020 MSL Level 1 (260 °C peak reflow), with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. It is rated for non-repetitive 10/1000 μs waveform surges and qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 100 V / 111 V at 1.0 mA test current - defines guaranteed breakdown threshold window |
| VC @ IPPM | ≤146 V at 10.3 A - clamping voltage during 10/1000 μs surge, critical for downstream IC survivability |
| PPPM | 1500 W - peak pulse power handling capability under standardized transient waveform |
| TJ max | +150 °C - enables use in under-hood automotive and high-ambient industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ90A-E3/57T | Lower PPPM (400 W), SMA (DO-214AC) package, same VWM/VBR range | Suitable for space-constrained consumer PCBs but not automotive under-hood thermal loads | Select when cost and board area are prioritized over 1500 W surge capacity and AEC-Q101 compliance |
| SMCJ90AHE3/57T | Same SMCG package and AEC-Q101 rating, but 1500 W PPPM and 100–111 V VBR identical to SMCG90AHE3/57T | Functionally identical; differs only in manufacturer's internal part numbering and traceability codes | Acceptable as direct material substitution where Vishay's SMCG-series sourcing continuity is required |
Compared with SMAJ90A-E3/57T and SMCJ90AHE3/57T, the SMCG90AHE3/57T delivers identical clamping performance and automotive qualification in the same footprint, while offering superior thermal dissipation (RθJA = 75 °C/W vs. ~100 °C/W for SMAJ) and higher surge endurance in demanding industrial deployments.

FAQ
What is the clamping voltage of SMCG90AHE3/57T at its rated peak pulse current?
The SMCG90AHE3/57T has a maximum clamping voltage (VC) of 146 V at its rated peak pulse current (IPPM) of 10.3 A under the standard 10/1000 μs waveform. This value ensures protected circuits remain below critical voltage thresholds during surge events, and it is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per the Vishay datasheet.
Is SMCG90AHE3/57T suitable for automotive applications?
Yes, SMCG90AHE3/57T is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS power domains. Its 150 °C maximum junction temperature, MSL Level 1 reflow rating, and glass-passivated junction support under-hood deployment where thermal and reliability demands are stringent.
What does the "HE3" suffix indicate in SMCG90AHE3/57T?
The "HE3" suffix in SMCG90AHE3/57T denotes RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature, HE3 indicates industrial-grade, halogen-free, RoHS-compliant, and AEC-Q101-qualified devices - distinguishing it from E3 (RoHS only) and HM3 (halogen-free + AEC-Q101) variants.
How does the SMCG (DO-215AB) package compare thermally to SMA (DO-214AC)?
The SMCG (DO-215AB) package used by SMCG90AHE3/57T offers lower thermal resistance than SMA: RθJA = 75 °C/W versus ~100 °C/W for typical SMA devices. This is achieved via larger copper pad areas and optimized leadframe geometry, enabling higher sustained power dissipation and improved reliability in high-ambient-temperature applications.
Can SMCG90AHE3/57T be used in bidirectional configurations?
No, SMCG90AHE3/57T is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and cathode-band marking. For bidirectional operation, Vishay specifies parts with the "CA" suffix (e.g., SMCG90CA). Using SMCG90AHE3/57T in reverse-biased signal paths would result in forward conduction and potential failure.
