Product details
Overview
SMBG16CA-M3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), <1.0 μA reverse leakage at VWM, and clamps to ≤26.0 V at 23.1 A peak pulse current - used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBG16CA-M3/5B datasheet, SMBG16CA-M3/5B pinout, SMBG16CA-M3/5B application, or SMBG16CA-M3/5B equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, 150 °C max junction temperature, low 20 °C/W junction-to-lead thermal resistance, and halogen-free RoHS compliance per M3 suffix.
Technical Context
This bidirectional TVS operates symmetrically in both polarities with identical VBR min/max (17.8–19.7 V) and clamping behavior (VC ≤ 26.0 V at IPPM = 23.1 A). Its glass-passivated junction ensures stable breakdown and low dynamic impedance under repetitive surge stress.
Designed for surface-mount automated assembly, it meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports 0.01% duty cycle repetitive surges, and delivers fast response time (<1 ns) with low incremental surge resistance - critical for protecting high-speed analog and digital signal paths against ISO 7637-2 and IEC 61000-4-5 threats.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins; defines safe signal swing range for protected line |
| VBR @ IT = 1 mA | 17.8–19.7 V - guaranteed breakdown threshold; ensures predictable turn-on during overvoltage events |
| VC @ IPPM = 23.1 A | ≤26.0 V - clamped voltage under 600 W 10/1000 μs surge; limits stress on downstream ICs like microcontrollers or transceivers |
| ID @ VWM | ≤1.0 μA - ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| PPPM | 600 W - peak pulse power handling capability; supports robust protection against automotive load dump and EFT bursts |
| TJ max | +150 °C - extended junction temperature rating enables use in under-hood automotive and industrial environments |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount gull-wing leaded case with matte tin-plated terminals; 0.235–0.255 inch (5.97–6.48 mm) body length, 0.130–0.155 inch (3.30–3.94 mm) width, 0.075–0.095 inch (1.90–2.41 mm) height; meets UL 94 V-0 flammability rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG16CA-E3/5B | Same electrical specs and SMBG package; RoHS-compliant but not halogen-free (E3 vs. M3) | Lacks halogen-free certification; acceptable for non-automotive industrial use where JESD201 Class 2 whisker resistance is not required | Select SMBG16CA-E3/5B when halogen-free material is not mandated and cost optimization is prioritized. |
| SMBJ16CA-M3 | Same VWM/VBR/VC ratings but in larger SMB (DO-214AA) package; higher IPPM (32.4 A) and PPPM (600 W same, but better thermal margin) | Requires larger PCB footprint; better suited for high-repetition-rate surge environments due to lower RθJA (85 °C/W vs. 100 °C/W) | Choose SMBJ16CA-M3 when enhanced thermal performance or legacy SMB footprint compatibility is needed. |
Compared with SMBG16CA-M3/5B, SMBG16CA-E3/5B offers identical protection performance without halogen-free assurance, while SMBJ16CA-M3 provides superior thermal dissipation in a larger package - enabling longer surge endurance in high-duty-cycle applications.

FAQ
What is the clamping voltage of SMBG16CA-M3/5B at its rated peak pulse current?
The SMBG16CA-M3/5B clamps to a maximum of 26.0 V at its peak pulse current of 23.1 A (10/1000 μs waveform). This value is measured under standardized test conditions with 0.2" × 0.2" copper pads per terminal and represents the upper limit of voltage imposed on protected circuitry during a full-rated surge event. The SMBG16CA-M3/5B maintains this clamping performance bidirectionally, ensuring consistent protection regardless of transient polarity.
Is SMBG16CA-M3/5B suitable for automotive applications?
Yes, SMBG16CA-M3/5B is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its 150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and halogen-free (M3) construction meet stringent automotive manufacturing and reliability requirements. The SMBG16CA-M3/5B has undergone temperature cycling, high-temperature reverse bias, and ESD testing per AEC-Q101 standards.
How does the M3 suffix differ from E3 in SMBG16CA-M3/5B?
The M3 suffix indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance without halogen-free assurance. Both share identical electrical specifications and SMBG (DO-215AA) packaging, but SMBG16CA-M3/5B is required for automotive and high-reliability industrial designs where halogen content restrictions and long-term intermetallic growth prevention are mandated. The SMBG16CA-M3/5B meets material categorization per Vishay doc#99912.
What is the reverse leakage current of SMBG16CA-M3/5B at its stand-off voltage?
At its 16 V stand-off voltage (VWM), the SMBG16CA-M3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This ultra-low leakage ensures minimal power loss and signal degradation in always-on or battery-powered systems. Leakage remains within specification across the full operating temperature range (−55 °C to +150 °C), supporting reliable operation in harsh environments. The SMBG16CA-M3/5B achieves this while maintaining symmetrical bidirectional characteristics.
Can SMBG16CA-M3/5B be used in place of a unidirectional TVS diode?
No - SMBG16CA-M3/5B is strictly bidirectional and lacks polarity marking; it conducts identically in both directions, making it unsuitable for DC-biased applications requiring unidirectional clamping (e.g., 5 V rail protection with defined anode/cathode orientation). For such cases, use unidirectional variants like SMBG16A-M3/5B. The SMBG16CA-M3/5B is optimized for AC-coupled or floating signal lines (e.g., CAN, USB D+/D−, audio) where polarity-agnostic suppression is required.
