Product details
Overview
SMBG10A-M3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMBG (DO-215AA) package, rated for 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR at 1 mA), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤17.0 V at 35.3 A peak surge current and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the SMBG10A-M3/5B datasheet, SMBG10A-M3/5B pinout, SMBG10A-M3/5B application, or SMBG10A-M3/5B equivalent, key selection criteria include unidirectional polarity, 10 V VWM, 17.0 V clamping voltage at rated IPPM, M3 halogen-free RoHS compliance, and SMBG package thermal resistance (RθJA = 100 °C/W).
Technical Context
This TVS diode operates as a clamping-type overvoltage protector with fast avalanche response (<1 ns), designed to shunt transient energy away from sensitive downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (≤5.0 μA at 10 V), while the unidirectional configuration provides forward conduction path only during reverse-biased surges.
The device is rated for repetitive 10/1000 μs waveform pulses at 0.01% duty cycle, with maximum junction temperature of +150 °C and thermal resistance of 20 °C/W junction-to-lead. It meets J-STD-020 MSL Level 1 and withstands 100 A non-repetitive 8.3 ms half-sine surge (IFSM) - critical for load-dump immunity in automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line bias margin. |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on under ESD/EFT stress. |
| VC @ IPPM | 17.0 V at 35.3 A - Clamping voltage during 600 W transient; limits downstream IC voltage stress to safe levels. |
| PPPM | 600 W (10/1000 μs) - Peak surge power handling; supports IEC 61000-4-5 Level 4 (4 kV) system-level testing. |
| IFSM | 100 A (8.3 ms half-sine) - Forward surge rating; enables use in automotive load-dump protection without series fuse dependency. |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood environments with minimal derating. |
| Package | SMBG (DO-215AA) - Surface-mount outline with 0.235" × 0.255" footprint; optimized for automated placement and thermal pad coupling. |
Pinout & Package
SMBG10A-M3/5B uses the SMBG (DO-215AA) package: molded plastic case with matte tin-plated leads, cathode indicated by a band on the body. Leads are solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential rail; completes clamping path during reverse transients. |
| Cathode | Reverse-biased surge input terminal | Connected to protected line (e.g., CAN_H, LIN, sensor supply); receives transient energy to trigger avalanche. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - required for engine control, ADAS, and body electronics. |
| Halogen-free & RoHS compliant (M3 suffix) | Meets global environmental regulations without compromising thermal or electrical performance; no brominated flame retardants in molding compound. |
| 600 W peak pulse power (10/1000 μs) | Supports high-energy transients such as ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Combination Wave (4 kV/2 Ω). |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during clamping - critical for protecting 12 V logic interfaces and microcontroller I/O pins. |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without moisture-induced popcorn failure or delamination. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-M3/5B | Same VWM (10 V), but lower PPPM = 600 W (same rating), higher VC = 17.0 V (identical), same SMB package but SMBJ outline (DO-214AB) - 0.205" × 0.220" vs SMBG's 0.235" × 0.255". | SMBJ10A-M3/5B has slightly smaller footprint and higher RθJA (~125 °C/W); less suitable for high-density automotive PCBs requiring optimal thermal pad area. | Select SMBG10A-M3/5B when board layout includes dedicated 5.0 mm × 5.0 mm copper pads per terminal for enhanced thermal dissipation. |
| 1.5SMC10AHE3/A | Same VWM (10 V), identical VC (17.0 V), but SMC (DO-214AB) package - larger than SMBG, higher IPPM (35.3 A same), PPPM = 1500 W (higher), not AEC-Q101 qualified. | 1.5SMC10AHE3/A supports higher surge energy but lacks automotive qualification; requires more board space and does not meet OEM component approval requirements. | Choose SMBG10A-M3/5B for AEC-Q101-compliant designs where space-constrained mounting and automotive validation are mandatory. |
Compared with SMBJ10A-M3/5B and 1.5SMC10AHE3/A, SMBG10A-M3/5B uniquely balances AEC-Q101 qualification, SMBG package thermal efficiency (RθJL = 20 °C/W), and precise 10 V stand-off tolerance - making it optimal for space-limited, thermally demanding automotive and industrial control applications.

FAQ
What is the maximum clamping voltage of SMBG10A-M3/5B at its rated peak pulse current?
The SMBG10A-M3/5B has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A, measured under the standard 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 and defines the upper voltage limit imposed on protected circuits during surge events. The SMBG10A-M3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG10A-M3/5B suitable for automotive applications requiring AEC-Q101 qualification?
Yes, SMBG10A-M3/5B is explicitly AEC-Q101 qualified per Vishay documentation, with test records covering HTOL, temperature cycling, HTRB, and mechanical shock. Its M3 suffix denotes halogen-free, RoHS-compliant construction meeting automotive material requirements. The SMBG10A-M3/5B is approved for use in engine control, body electronics, and ADAS subsystems where component-level automotive qualification is mandatory.
What is the meaning of the "M3" and "5B" suffixes in SMBG10A-M3/5B?
The "M3" suffix indicates halogen-free, RoHS-compliant, industrial-grade construction with JESD 201 Class 2 whisker resistance. The "5B" denotes the packaging format: 13-inch diameter plastic tape and reel containing 3200 units. This differs from "52", which specifies 7-inch reels of 750 units. Both formats use the same SMBG die and electrical specifications - SMBG10A-M3/5B is functionally identical to SMBG10A-M3/52 except for reel size and quantity.
Does SMBG10A-M3/5B have bidirectional capability?
No, SMBG10A-M3/5B is a unidirectional TVS diode, as confirmed by its part number ending in "A" (not "CA") and its specified polarity: cathode marked with a band, anode unmarked. Bidirectional variants like SMBG10CA exist in the same family but exhibit symmetrical breakdown in both directions. Using SMBG10A-M3/5B in bidirectional applications would require two devices or a dedicated CA version.
What is the thermal resistance from junction to ambient for SMBG10A-M3/5B?
The typical thermal resistance from junction to ambient (RθJA) for SMBG10A-M3/5B is 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Vishay's datasheet. This value assumes standard JEDEC test conditions and directly impacts power derating above 25 °C ambient. For higher-power or elevated-temperature operation, the SMBG10A-M3/5B's RθJL of 20 °C/W to the lead should be used in board-level thermal modeling.
