Product details
Overview
SMCG6.5A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in DO-215AB (SMCG) package, with 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 11.2 V clamping voltage (VC) at 133.9 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) rating for 10/1000 µs waveform. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCG6.5A-M3/57T datasheet, SMCG6.5A-M3/57T pinout, SMCG6.5A-M3/57T application, or SMCG6.5A-M3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, halogen-free RoHS compliance (M3 suffix), 150 °C max junction temperature, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a clamping-type TVS diode, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability with VF = 3.5 V at IF = 100 A, enabling bidirectional protection when paired with complementary devices.
The SMCG6.5A-M3/57T is rated for 200 A non-repetitive forward surge current (IFSM) under 8.3 ms half-sine wave, and exhibits RθJA = 75 °C/W and RθJL = 15 °C/W thermal resistance - critical for thermal design in high-power transient suppression circuits where PCB copper area directly impacts derating above 25 °C ambient.
Key Specifications

FAQ
What is the clamping voltage of SMCG6.5A-M3/57T under a 10/1000 µs surge?
The SMCG6.5A-M3/57T has a maximum clamping voltage (VC) of 11.2 V at 133.9 A peak pulse current (IPPM) for a 10/1000 µs waveform. This value is measured under standardized test conditions with 8.0 mm × 8.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCG6.5A-M3/57T maintains this clamping performance across its qualified operating temperature range.
Is SMCG6.5A-M3/57T suitable for automotive applications?
Yes, SMCG6.5A-M3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and infotainment power supplies. Its construction features glass-passivated junctions, halogen-free molding compound (M3 suffix), and MSL Level 1 moisture sensitivity - all verified per automotive reliability standards. The SMCG6.5A-M3/57T is designed to withstand harsh thermal and mechanical stress encountered in vehicle environments.
What does the "M3" suffix indicate in SMCG6.5A-M3/57T?
The "M3" suffix in SMCG6.5A-M3/57T denotes halogen-free, RoHS-compliant construction with industrial-grade reliability and JESD 201 Class 2 whisker resistance. It distinguishes this variant from "E3" (standard RoHS) and "HM3" (AEC-Q101 + halogen-free). The SMCG6.5A-M3/57T meets UL 94 V-0 flammability requirements and is optimized for environmentally regulated industrial and automotive supply chains.
How does SMCG6.5A-M3/57T differ from bidirectional variants like SMCG6.5CA?
SMCG6.5A-M3/57T is unidirectional with cathode band marking and forward conduction capability (VF = 3.5 V at 100 A), while SMCG6.5CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. The SMCG6.5A-M3/57T is used where only positive transients require suppression or where DC bias exists; SMCG6.5CA suits AC-coupled or floating signal lines. Electrical parameters such as VWM and VC differ accordingly.
What is the thermal resistance of SMCG6.5A-M3/57T, and how does it affect layout?
The SMCG6.5A-M3/57T has RθJA = 75 °C/W (junction-to-ambient, on 8.0 mm × 8.0 mm pads) and RθJL = 15 °C/W (junction-to-lead). These values mean that for every watt of steady-state power dissipated, junction temperature rises 75 °C above ambient - so at its 6.5 W PD rating, ΔTJ-A = 488 °C (exceeding TJ max). Thus, SMCG6.5A-M3/57T is intended for transient-only duty; layout must prioritize short, wide traces to leads and avoid excessive copper isolation to maintain thermal path integrity for surge events.
