Product details
Overview
SMBG5.0A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMBG (DO-215AA) package, designed for primary overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 9.2 V at 65.2 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG5.0A-M3/52 datasheet, SMBG5.0A-M3/52 pinout, SMBG5.0A-M3/52 application, or SMBG5.0A-M3/52 equivalent, key selection criteria include its 5.0 V stand-off rating, low clamping ratio (VC/VBR ≈ 1.33), halogen-free RoHS-compliant M3 termination, 100 A IFSM surge capability, and suitability for protecting CAN, LIN, sensor supply rails, and low-voltage microcontroller I/O lines against ESD and load dump transients.
Technical Context
This TVS operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its 100 °C/W junction-to-ambient thermal resistance requires adherence to the specified 0.2" × 0.2" copper pad layout for rated 600 W pulse handling.
The SMBG5.0A-M3/52 complies with ANSI/IEEE C62.35 surge standards and UL 497B recognition (QVGQ2), supporting repetitive 0.01% duty cycle surges. It is rated for -55 °C to +150 °C operating junction temperature and meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow compatibility (260 °C peak).

FAQ
What is the clamping voltage of SMBG5.0A-M3/52 and how does it protect downstream circuits?
The SMBG5.0A-M3/52 has a maximum clamping voltage (VC) of 9.2 V at 65.2 A peak pulse current (10/1000 µs waveform). This value defines the upper voltage limit imposed on the protected line during a surge event. By holding the transient voltage to ≤9.2 V, the SMBG5.0A-M3/52 prevents overvoltage stress on downstream components such as microcontrollers, transceivers, or sensors rated for 5 V or 3.3 V operation-ensuring system-level robustness against ISO 7637-2 and IEC 61000-4-5 threats.
Is SMBG5.0A-M3/52 suitable for automotive applications, and what qualifications does it hold?
Yes, SMBG5.0A-M3/52 is explicitly qualified to AEC-Q101 for automotive use and recognized under UL 497B (file E136766). Its construction-including glass-passivated junction, halogen-free M3 termination, and operation up to +150 °C junction temperature-meets requirements for engine control units, body electronics, and ADAS sensor modules. The SMBG5.0A-M3/52 is validated for repetitive surge duty cycles and thermal cycling typical of under-hood environments.
How does the SMBG5.0A-M3/52 differ from the SMBJ5.0A-M3/52 in practical design terms?
The SMBG5.0A-M3/52 provides 600 W peak pulse power versus 400 W for the SMBJ5.0A-M3/52, enabling reliable protection against higher-energy transients like ISO 7637-2 Pulse 5a/b (load dump). Both share the same VWM (5.0 V), VBR (6.4–7.07 V), and SMBG package, but the SMBG5.0A-M3/52's superior power handling and AEC-Q101 qualification make it mandatory for automotive 12 V systems where the SMBJ5.0A-M3/52 would thermally saturate.
What is the meaning of the "M3" suffix in SMBG5.0A-M3/52?
The "M3" suffix in SMBG5.0A-M3/52 indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance and J-STD-002 solderability standards. Unlike "E3" (standard RoHS), M3 ensures compliance with strict environmental regulations in automotive and industrial markets where brominated flame retardants and halogen content are restricted-without sacrificing solder joint reliability or thermal performance.
Can SMBG5.0A-M3/52 be used for bidirectional transient suppression?
No, SMBG5.0A-M3/52 is a unidirectional TVS diode, identifiable by the cathode band marking on the SMBG package. For bidirectional protection, Vishay offers the SMBG5.0CA-M3/52 variant (with "CA" suffix), which provides symmetrical clamping in both polarities and is intended for AC-coupled or floating signal lines. Using SMBG5.0A-M3/52 in bidirectional configurations risks forward conduction and permanent damage during negative transients.
