Product details
Overview
SMBJ16CD-M3/I from Vishay is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 16 V standoff voltage (VWM), 18.1–19.4 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamping voltage of 25.6 V at 23.4 A. It protects signal lines and power rails in sensor interfaces and industrial control systems against ESD and inductive switching transients.
For engineers reviewing the SMBJ16CD-M3/I datasheet, SMBJ16CD-M3/I pinout, SMBJ16CD-M3/I application, or SMBJ16CD-M3/I equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal derating curves, MSL Level 1 reflow compatibility, and RoHS/halogen-free compliance - all critical for automotive-grade transient protection layout and reliability validation.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of transient polarity. Its 18.1–19.4 V VBR range at 1 mA ensures tight ±3.5 % tolerance, enabling precise overvoltage threshold alignment with 16 V nominal rails.
Designed for fast response to sub-nanosecond transients, it achieves clamping within <1 ps while maintaining low incremental surge resistance and 0.5 μA max reverse leakage at VWM - essential for low-power sensor front-ends and battery-operated IoT nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 18.1 V / 19.4 V at 1 mA - tight ±3.5 % breakdown tolerance ensures predictable turn-on |
| VC @ IPPM | 25.6 V at 23.4 A - clamping voltage limits downstream IC stress during 600 W surges |
| PPPM | 600 W (10/1000 μs waveform) - robust protection against lightning-induced and inductive-switching transients |
| ID @ VWM | ≤0.5 μA - negligible leakage preserves signal integrity and battery life in always-on circuits |
| TJ max | 150 °C - supports operation in under-hood automotive and industrial ambient environments |
| MSL Level | Level 1 (JEDEC J-STD-020) - compatible with standard 260 °C peak reflow profiles without preconditioning |

Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA current loop) from load dump and relay coil flyback in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point, shunting transients before they reach op-amp input stages. Use Value: Limits induced voltage to ≤25.6 V during 23.4 A surges, preventing op-amp latch-up and preserving 16-bit ADC linearity. | Use Scenario: Safeguarding LIN bus transceiver I/O pins against battery reversal and jump-start transients in door module ECUs. IC Role / Device Role / Timing Role: Primary board-level TVS mounted adjacent to connector, providing first-line defense before internal ESD diodes. Use Value: Clamps 10/1000 μs surges to 25.6 V while maintaining <0.5 μA leakage - avoids false wake-up and preserves sleep current budget. |
| Telecom Power Input | Consumer USB-C Port Protection |
Use Scenario: Guarding 12–19 V DC input rails of PoE-powered access points against Ethernet cable-induced surges. IC Role / Device Role / Timing Role: Secondary-stage TVS after primary MOV, handling fast-rising residual transients that bypass bulk suppression. Use Value: Responds in <1 ps to clamp 600 W events, reducing stress on downstream DC/DC controller MOSFETs rated for 30 V max. | Use Scenario: Protecting VBUS and CC lines in portable docking stations against hot-plug ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional TVS placed between USB-C receptacle and port controller, symmetrically suppressing ±15 kV contact ESD per IEC 61000-4-2. Use Value: Delivers consistent 25.6 V clamping regardless of ESD polarity, eliminating need for dual unidirectional devices and saving PCB area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA-E3/52 (Vishay) | Same VWM/VBR/PPPM specs; differs only in packaging (tape-and-reel quantity and reel diameter) | No functional difference - identical electrical and thermal performance | Select based on logistics preference: SMBJ16CD-M3/I uses 13" reel (3200 pcs); SMBJ16CA-E3/52 uses 7" reel (750 pcs) |
| P6SMB16CA (Littelfuse) | Same SMB package, 16 V VWM, 18.9–20.9 V VBR range (±5 %), 600 W PPPM, but 27.5 V VC @ 21.9 A | Higher clamping voltage reduces margin for 24 V tolerant receivers; requires verification against system VIH/VIL thresholds | Use only if 27.5 V clamping is acceptable; SMBJ16CD-M3/I offers tighter VBR and lower VC for precision rail protection |
Compared with SMBJ16CA-E3/52, SMBJ16CD-M3/I offers identical protection performance with optimized logistics for high-volume SMT; versus P6SMB16CA, SMBJ16CD-M3/I provides 1.9 V lower clamping voltage and ±3.5 % VBR tolerance - critical for 16 V rail coordination and ESD-sensitive analog interfaces.

FAQ
What is the exact breakdown voltage range for SMBJ16CD-M3/I?
The SMBJ16CD-M3/I has a guaranteed breakdown voltage (VBR) range of 18.1 V to 19.4 V at 1 mA test current, corresponding to ±3.5 % tolerance around the nominal 16 V standoff voltage. This tight specification is confirmed in Vishay's official datasheet revision 09-Jan-2024 (Document Number: 87606), ensuring predictable turn-on behavior for coordinated overvoltage protection schemes.
Is SMBJ16CD-M3/I unidirectional or bidirectional?
SMBJ16CD-M3/I is a bidirectional Transient Voltage Suppressor, as indicated by the "CD" suffix per Vishay's naming convention. It exhibits symmetrical clamping characteristics in both polarities, with no cathode band marking on the SMB (DO-214AA) package. This enables single-device protection of AC-coupled lines, differential buses like LIN or RS-485, and floating power domains without polarity concerns.
What is the maximum clamping voltage of SMBJ16CD-M3/I and at what current?
The SMBJ16CD-M3/I clamps to a maximum of 25.6 V when subjected to its peak pulse current (IPPM) of 23.4 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and documented in the Electrical Characteristics table of Vishay's datasheet (87606), directly defining the upper voltage limit imposed on protected circuitry during surge events.
Does SMBJ16CD-M3/I meet lead-free and RoHS requirements?
Yes, SMBJ16CD-M3/I is halogen-free, RoHS-compliant, and qualified to JESD 201 Class 2 for tin whisker resistance. The "M3" suffix explicitly denotes industrial-grade, lead-free construction with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. These attributes are specified in the Mechanical Data section of Vishay's datasheet (87606, revision 09-Jan-2024).
What is the thermal resistance and power derating behavior of SMBJ16CD-M3/I?
SMBJ16CD-M3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 5.0 mm × 5.0 mm copper pad. Its steady-state power dissipation drops from 1.0 W at 25 °C ambient to zero at 150 °C, following the derating curve in Figure 5 of the datasheet. This defines safe continuous operation boundaries in thermally constrained enclosures.
