Overview
SMBG10CA-M3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on signal or power lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMBG10CA-M3/52 datasheet, SMBG10CA-M3/52 pinout, SMBG10CA-M3/52 application, or SMBG10CA-M3/52 equivalent, key selection criteria include bidirectional surge capability, AEC-Q101 qualification, halogen-free RoHS compliance, and low clamping voltage under standardized 10/1000 μs surge conditions.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and leakage characteristics across reverse and forward directions. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the SMBG package supports automated SMT placement and meets MSL Level 1 per J-STD-020.
The device is rated for -55 °C to +150 °C operating junction temperature, exhibits 100 °C/W typical thermal resistance (junction-to-ambient), and delivers 600 W peak pulse power dissipation under 0.01% duty cycle conditions - validated with 0.2" × 0.2" copper pads per terminal.

FAQ
What is the clamping voltage of SMBG10CA-M3/52 at its rated peak pulse current?
The SMBG10CA-M3/52 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current of 35.3 A, measured using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream ICs remain within safe voltage limits during surge events. The SMBG10CA-M3/52 achieves this with a low clamping ratio of approximately 1.5 relative to its minimum breakdown voltage.
Is SMBG10CA-M3/52 suitable for automotive applications?
Yes, SMBG10CA-M3/52 is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its halogen-free M3 suffix, -55 °C to +150 °C operating range, and validated performance under temperature cycling and HTRB testing confirm suitability for under-hood and cabin environments. The SMBG10CA-M3/52 meets all requirements for ISO 7637-2 and IEC 61000-4-5 compliance testing.
How does the SMBG10CA-M3/52 differ from unidirectional variants like SMBG10A-M3/52?
The SMBG10CA-M3/52 is bidirectional, providing symmetrical clamping for both positive and negative transients, whereas SMBG10A-M3/52 is unidirectional and only protects against reverse-polarity surges. The CA suffix indicates identical VBR, VC, and leakage in both directions - essential for AC-coupled lines or floating references. SMBG10CA-M3/52 has no polarity marking, unlike the cathode-banded SMBG10A-M3/52.
What is the thermal resistance of SMBG10CA-M3/52, and how does it affect layout design?
The SMBG10CA-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's DO-215AA specification. To maintain reliability under repeated surges, designers must allocate adequate copper area and avoid excessive trace length - especially critical in high-temperature automotive zones where ambient exceeds 85 °C.
Does SMBG10CA-M3/52 meet RoHS and halogen-free requirements?
Yes, the M3 suffix on SMBG10CA-M3/52 explicitly denotes halogen-free, RoHS-compliant construction per JEDEC JESD201 Class 2 whisker resistance and Vishay's material categorization standard. It uses matte tin-plated leads and UL 94 V-0 molding compound. This makes SMBG10CA-M3/52 suitable for environmentally regulated markets including EU automotive and industrial equipment, with full documentation traceability through Vishay's compliance portal.
