Product details
Overview
SMCG60A-M3/57T 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 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 15.5 A peak pulse current (IPPM), and clamps to ≤96 V under surge. It is halogen-free, RoHS-compliant, AEC-Q101 qualified, and used in automotive sensor signal lines and power rail protection.
For engineers reviewing the SMCG60A-M3/57T datasheet, SMCG60A-M3/57T pinout, SMCG60A-M3/57T application, or SMCG60A-M3/57T equivalent, key selection criteria include unidirectional polarity, DO-215AB thermal performance (RθJA = 75 °C/W), 150 °C max junction temperature, low incremental surge resistance, and compliance with UL 497B and AEC-Q101 for automotive-grade reliability.
Technical Context
The SMCG60A-M3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low clamping ratio (VC/VBR ≈ 1.3–1.4). Its unidirectional configuration enables integration into DC power rails and signal paths where polarity-sensitive suppression is required.
Designed for surface-mount automated placement, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. The DO-215AB package provides mechanical robustness and thermal dissipation via 8.0 mm × 8.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - ensures reliable avalanche initiation across process variation |
| VC @ IPPM | ≤96 V at 15.5 A - defines worst-case clamping level during 10/1000 µs surge |
| PPPM | 1500 W - peak surge energy handling capability under standardized waveform |
| TJ max | +150 °C - supports operation in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance enabling 6.5 W steady-state dissipation on recommended pad layout |
| Package | SMCG (DO-215AB) - low-profile SMD outline with cathode band marking for polarity identification |
Pinout & Package
SMCG60A-M3/57T is housed in the SMCG (DO-215AB) surface-mount package: a dual-leaded, gull-wing configuration with cathode marked by a band on the anode-side end cap. Leads are matte tin-plated and solderable per J-STD-002. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for rated thermal and surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or low-impedance return path | Provides reference node for clamping action; must be routed with low-inductance path to minimize overshoot |
| Cathode | Current exit point in forward bias; connected to protected line or supply rail | Marked by band; carries full surge current during transient events and determines polarity of protection |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| Halogen-free & RoHS-compliant (M3 suffix) | Meets environmental compliance requirements for industrial and automotive production without compromising surge robustness |
| Low incremental surge resistance | Enables tighter clamping (VC/VBR ratio ~1.34) and reduced let-through energy to downstream ICs |
| Glass passivated junction | Ensures long-term stability and reliability under repeated surge stress and high humidity conditions |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow profile up to 260 °C peak without preconditioning |
Applications
| Automotive Sensor Protection | Industrial Power Rail Clamping |

IC Role / Device Role / Timing Role: First-line unidirectional suppressor upstream of buck converter and load switch. Use Value: 60 V VWM aligns with USB PD 3.0 PPS profiles; 96 V VC prevents exceedance of 100 V MOSFET drain ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/57T (Vishay) | Same VWM/VBR/PPPM specs but in SMA (DO-214AC) package; RθJA = 85 °C/W; no AEC-Q101 qualification | Limited to industrial/commercial use; lower thermal performance requires larger PCB copper area | Select when AEC-Q101 is not required and existing SMA footprint is preferred |
| 1.5KE60A (ON Semiconductor) | Through-hole DO-201 package; same 60 V VWM but higher VC (100 V); 1500 W rating; no AEC-Q101 or halogen-free certification | Not suitable for automated SMT lines; incompatible with space-constrained automotive modules | Choose only for legacy through-hole designs where rework tolerance outweighs SMT efficiency |
Compared with SMAJ60A-E3/57T and 1.5KE60A, the SMCG60A-M3/57T delivers superior automotive qualification, halogen-free compliance, and optimized thermal resistance in a compact DO-215AB footprint-making it the preferred choice for new SMT-based automotive and industrial designs requiring long-term reliability.

FAQ
What is the maximum clamping voltage of the SMCG60A-M3/57T under a 10/1000 µs surge?
The SMCG60A-M3/57T has a maximum clamping voltage (VC) of 96 V when subjected to its rated peak pulse current (IPPM) of 15.5 A under the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and reflects worst-case performance for design margining. The SMCG60A-M3/57T maintains this clamping level consistently due to its glass-passivated avalanche structure and low incremental resistance.
Is the SMCG60A-M3/57T suitable for automotive applications?
Yes, the SMCG60A-M3/57T is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, ADAS sensor interfaces, and body electronics. Its halogen-free (M3) construction, MSL Level 1 rating, and guaranteed operation from –55 °C to +150 °C make it appropriate for under-hood and cabin environments. The SMCG60A-M3/57T meets UL 497B recognition and supports long-term reliability under repeated surge stress per automotive test standards.
How does the DO-215AB package of the SMCG60A-M3/57T compare thermally to SMA (DO-214AC)?
The SMCG60A-M3/57T in DO-215AB offers a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W on the recommended 8.0 mm × 8.0 mm copper pad layout, which is 10 °C/W better than the SMAJ60A-E3/57T (85 °C/W). This improved thermal performance allows higher sustained power dissipation and greater margin in high-temperature automotive applications. The SMCG60A-M3/57T achieves this via wider lead frames and optimized internal thermal path design within the same footprint class.
What does the "M3" suffix indicate in SMCG60A-M3/57T?
"M3" denotes halogen-free, RoHS-compliant, industrial-grade construction per Vishay's ordering nomenclature. It confirms compliance with IEC 61249-2-21 and JEDEC J-STD-20, with no brominated flame retardants or antimony trioxide. Unlike "E3" (standard RoHS), "M3" satisfies stricter environmental mandates for automotive Tier 1 suppliers and green manufacturing programs. The SMCG60A-M3/57T retains identical electrical specifications and AEC-Q101 qualification as its HE3/HM3 automotive variants.
Can the SMCG60A-M3/57T be used in bidirectional configurations?
No-the SMCG60A-M3/57T is a unidirectional TVS diode, indicated by the "A" suffix (vs. "CA" for bidirectional). Its cathode band marks the polarity-sensitive terminal, and it conducts only during positive transients relative to ground. For bidirectional protection, Vishay specifies parts like SMCG60CA with symmetrical breakdown in both directions. Using SMCG60A-M3/57T in bidirectional circuits risks failure during negative surges, as it lacks reverse conduction capability.
