Product details
Overview
SMCG90CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for robust overvoltage protection of sensitive electronics. It features a 90 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), clamping voltage of 146 V at 10.3 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG90CA-M3/57T datasheet, SMCG90CA-M3/57T pinout, SMCG90CA-M3/57T application, or SMCG90CA-M3/57T equivalent, this device is selected for high-energy surge suppression in automotive power nets, industrial sensor interfaces, and telecom line protection where bidirectional clamping, low incremental surge resistance, and halogen-free RoHS compliance are required.
Technical Context
The SMCG90CA-M3/57T operates as a bidirectional avalanche diode with symmetrical breakdown characteristics - minimum VBR = 100 V and maximum VBR = 111 V at 1 mA test current. Its clamping behavior under 10/1000 μs surge pulses is defined by VC = 146 V at IPPM = 10.3 A, with thermal resistance RθJA = 75 °C/W on standard 8.0 mm × 8.0 mm copper pads.
It meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C), supports automated SMT placement, and uses glass-passivated junction technology for stable long-term performance. The device has no polarity marking due to its bidirectional construction and is rated for TJ = –55 °C to +150 °C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe working range for protected circuitry. |
| VBR (min/max) | 100 V / 111 V at 1 mA - Breakdown voltage tolerance band; ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | 146 V at 10.3 A - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream components. |
| PPPM | 1500 W - Peak pulse power handling capability; enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) in properly designed layouts. |
| ID @ VWM | 1.0 μA - Reverse leakage at stand-off voltage; negligible loading on signal or power lines during normal operation. |
| TJ max. | +150 °C - Maximum junction temperature; supports under-hood automotive use and high-ambient industrial environments. |
| Package | SMCG (DO-215AB) - Low-profile, gull-wing SMT package with matte tin-plated leads; optimized for automated assembly and thermal dissipation. |
Pinout & Package
SMCG90CA-M3/57T uses the SMCG (DO-215AB) surface-mount package: a symmetrical, bidirectional gull-wing case with two terminals and no polarity marking. The package measures 7.87 mm × 9.64 mm × 2.41 mm (L × W × H), features UL 94 V-0 molding compound, and mounts on 8.0 mm × 8.0 mm copper pads per terminal for rated power derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on instantaneous polarity; no functional distinction - symmetric conduction path. |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; bidirectional operation requires no orientation during placement. |
Key Features

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 | Unidirectional; lower PPPM (400 W); same VWM (90 V); SMA (DO-214AC) package. | Limited to DC-biased circuits; insufficient for AC or floating-line protection requiring bidirectional response. | Select only when polarity is fixed and surge energy is ≤400 W - not suitable as direct replacement for SMCG90CA-M3/57T in bidirectional systems. |
| SMCJ90CA | Bidirectional; same VWM (90 V); higher PPPM (1500 W); identical SMCG package; but M3 suffix not guaranteed (standard version may be halogen-containing). | Matches electrical and mechanical specs exactly, but lacks documented halogen-free certification unless specified as -M3. | Use SMCJ90CA-M3 if available; otherwise SMCG90CA-M3/57T ensures verified halogen-free compliance and tape-and-reel packaging for SMT line integration. |
Compared with SMAJ90A-E3/57T and SMCJ90CA, the SMCG90CA-M3/57T uniquely combines AEC-Q101 qualification, halogen-free construction, and guaranteed bidirectional 1500 W surge capability in a DO-215AB footprint - making it the preferred choice for automotive and high-reliability industrial designs requiring full compliance traceability.

FAQ
What is the breakdown voltage range for SMCG90CA-M3/57T?
The SMCG90CA-M3/57T has a guaranteed breakdown voltage (VBR) range of 100 V to 111 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This tight VBR window ensures consistent clamping behavior across temperature and production lots, directly supporting design margin calculations for protected circuits. The value is confirmed in the Vishay document 88457, Table on page 2.
Is SMCG90CA-M3/57T suitable for automotive applications?
Yes, SMCG90CA-M3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its –55 °C to +150 °C operating range, MSL Level 1 reflow compatibility, and halogen-free construction meet Tier 1 OEM requirements. The "HM3" and "HE3" base P/N variants are also AEC-Q101 qualified, confirming the family's automotive readiness - and SMCG90CA-M3/57T inherits this qualification per Vishay's ordering matrix.
What does the "M3" suffix mean in SMCG90CA-M3/57T?
The "M3" suffix in SMCG90CA-M3/57T indicates halogen-free, RoHS-compliant construction meeting JEDEC JESD201 Class 2 whisker resistance requirements. It distinguishes the part from "E3" (RoHS-compliant but not halogen-free) and "HM3" (AEC-Q101 qualified + halogen-free). Per Vishay's mechanical data, M3 parts use matte tin-plated leads and UL 94 V-0 molding compound - all verified in document 88457, page 1.
How is the clamping voltage of SMCG90CA-M3/57T determined?
The clamping voltage (VC) of SMCG90CA-M3/57T is 146 V, measured at a peak pulse current (IPPM) of 10.3 A using the standardized 10/1000 μs waveform per IEC 61000-4-5. This value reflects actual device behavior under surge stress and is not calculated - it is a measured specification provided in the Electrical Characteristics table (page 2 of document 88457) and forms the basis for downstream component voltage margining.
Does SMCG90CA-M3/57T require polarity-aware PCB layout?
No, SMCG90CA-M3/57T is a bidirectional TVS diode with symmetrical terminals and no cathode band or polarity marking. Both terminals function identically regardless of applied voltage polarity - enabling simplified PCB layout, elimination of orientation checks during assembly, and suitability for AC-coupled or floating signal paths. This is explicitly stated in the "Polarity" section of document 88457, page 1.
