Product details
Overview
SMCG5.0A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping 10/1000 µs surge transients up to 1500 W. It features 6.40 V minimum breakdown voltage (VBR), 5.0 V maximum stand-off voltage (VWM), and 9.20 V clamping voltage (VC) at 163 A peak pulse current - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power rails.
For engineers reviewing the SMCG5.0A-M3/57T datasheet, SMCG5.0A-M3/57T pinout, SMCG5.0A-M3/57T application, or SMCG5.0A-M3/57T equivalent, this device delivers AEC-Q101 qualification, halogen-free RoHS compliance, MSL Level 1 rating, low incremental surge resistance, and fast response time - critical for robust ESD and load-dump protection in space-constrained PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior under repetitive surge stress. Its thermal resistance (RθJA = 75 °C/W) and junction temperature limit (TJ = 150 °C) are specified with 8.0 mm × 8.0 mm copper pads per terminal, enabling reliable power dissipation up to 6.5 W at 50 °C ambient.
The SMCG5.0A-M3/57T meets ANSI/IEEE C62.35 standards for surge suppression and is rated for non-repetitive 8.3 ms half-sine forward surge current of 200 A. Its 10/1000 µs waveform response ensures effective suppression of inductive switching transients and ISO 7637-2 load-dump pulses in 12 V automotive systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same DO-214AC (SMA) package; lower PPPM (400 W), higher VC (13.4 V), and larger RθJA (110 °C/W). | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use where automotive reliability is not required. | Select SMAJ5.0A only if board space allows larger SMA footprint and 1500 W surge rating is unnecessary. |
| SMCJ5.0A | Same DO-214AB (SMC) package; identical PPPM (1500 W) but higher VC (10.8 V) and lower IPPM (139 A) at same VWM. | Larger body size increases PCB area; lacks M3 halogen-free designation unless explicitly ordered as SMCJ5.0A-M3. | Choose SMCJ5.0A-M3 only when DO-215AB's low profile is not critical and existing SMC footprints must be reused. |
Compared with SMAJ5.0A and SMCJ5.0A, the SMCG5.0A-M3/57T offers superior thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification, and halogen-free compliance in the smallest possible DO-215AB footprint - making it optimal for next-generation automotive and space-constrained industrial designs requiring full 1500 W surge capability.

FAQ
What is the clamping voltage of SMCG5.0A-M3/57T at its rated peak pulse current?
The SMCG5.0A-M3/57T has a maximum clamping voltage (VC) of 9.20 V at 163 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCG5.0A-M3/57T maintains this clamping performance consistently due to its glass-passivated junction and low incremental surge resistance.
Is SMCG5.0A-M3/57T suitable for automotive applications?
Yes, SMCG5.0A-M3/57T is AEC-Q101 qualified and rated for operating junction temperatures from –55 °C to +150 °C, making it suitable for under-hood and ECU applications. Its 200 A IFSM rating supports ISO 7637-2 load-dump immunity, and the M3 suffix confirms halogen-free, RoHS-compliant construction required by Tier 1 automotive suppliers. The SMCG5.0A-M3/57T is explicitly listed in Vishay's AEC-Q101 qualified product matrix for transient suppression.
What does the "M3" suffix indicate in SMCG5.0A-M3/57T?
"M3" denotes halogen-free, RoHS-compliant construction meeting IEC 61249-2-21 and JEDEC J-STD-20D standards, with matte tin-plated leads qualified per JESD 22-B102 and J-STD-002. Unlike E3 variants, M3 parts contain no brominated flame retardants or chlorine-based compounds, supporting environmentally regulated manufacturing and end-of-life recycling. The SMCG5.0A-M3/57T also meets JESD 201 Class 2 whisker resistance requirements.
How does SMCG5.0A-M3/57T differ from bidirectional versions like SMCG5.0CA?
The SMCG5.0A-M3/57T is unidirectional with cathode-band polarity, optimized for DC rail protection where surge direction is known (e.g., 5 V supply to ground). In contrast, SMCG5.0CA is bidirectional, offering symmetric clamping for AC-coupled or floating signal lines. Electrical differences include SMCG5.0CA's doubled ID limit (2000 µA vs. 1000 µA) for VWM ≤10 V and distinct marking codes (GDE vs. BDE). The SMCG5.0A-M3/57T cannot substitute for SMCG5.0CA in AC applications without circuit redesign.
What is the thermal resistance of SMCG5.0A-M3/57T, and how does it affect layout?
The SMCG5.0A-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet Figure 6. To achieve rated 6.5 W power dissipation at 50 °C ambient, designers must allocate sufficient copper area and avoid thermal bottlenecks - undersized pads will raise junction temperature and reduce surge endurance. The SMCG5.0A-M3/57T's RθJA is 35 °C/W lower than SMAJ5.0A, enabling tighter thermal margins.
