Product details
Overview
SMBJ16D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 16 V stand-off voltage (VWM), 18.1–19.4 V breakdown voltage (VBR) at 1 mA, 25.6 V maximum clamping voltage (VC) at 23.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ16D-M3/H datasheet, SMBJ16D-M3/H pinout, SMBJ16D-M3/H application, or SMBJ16D-M3/H equivalent, key selection criteria include unidirectional polarity, ±3.5% VBR tolerance, low leakage (<0.5 μA at VWM), MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction suitable for automated SMT assembly.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR to limit transient energy. Its 20 °C/W junction-to-mount thermal resistance enables effective heat dissipation under surge conditions when mounted on recommended PCB copper pads.
The device complies with ANSI/IEEE C62.35 for surge protection, supports repetitive 0.01% duty cycle surges, and meets UL 497B recognition (QVGQ2) for both unidirectional and bidirectional variants - though SMBJ16D-M3/H is strictly unidirectional with cathode band marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 16 V - maximum continuous reverse operating voltage before significant leakage begins; defines safe DC/AC working range. |
| VBR (Breakdown Voltage) | 18.1–19.4 V at 1 mA - precise avalanche onset range enabling tight overvoltage margin control in protection circuits. |
| VC (Clamping Voltage) | 25.6 V at 23.4 A IPPM - peak voltage seen by protected circuit during 10/1000 μs transient; determines minimum IC withstand rating. |
| PPPM (Peak Pulse Power) | 600 W - surge energy handling capability per single 10/1000 μs waveform; defines robustness against lightning or inductive spikes. |
| ID (Reverse Leakage) | <0.5 μA at 16 V - negligible standby current that avoids loading sensitive signal or bias networks. |
| RθJM (Junction-to-Mount) | 20 °C/W - thermal resistance enabling reliable power derating when soldered to minimum 5.0 mm × 5.0 mm copper pad. |
| MSL Level | Level 1 per J-STD-020 - no floor life limitation; supports standard reflow without baking preconditioning. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Cathode indicated by molded band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; forms current sink during transient clamping. |
| Cathode | High-side connection point | Connected to protected line (e.g., VBUS, signal rail); carries surge current into anode during reverse avalanche. |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables predictable clamping threshold across production lots, reducing design margin uncertainty in safety-critical protection stages. |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when combined with appropriate series impedance. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD or switching noise), improving protection fidelity. |
| MSL Level 1, LF peak 260 °C | Compatible with standard lead-free reflow profiles without moisture-related delamination risk. |
| UL 497B recognized (QVGQ2) | Validates suitability for telecom and industrial interface protection where regulatory compliance is mandatory. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-M3/H | Bidirectional variant with same VWM (16 V), but symmetric clamping in both polarities; VBR min/max widened to 18.1–20.8 V. | Required where AC-coupled or floating signal lines (e.g., RS-485, audio) need protection from bipolar transients. | Select SMBJ16A-M3/H only if bidirectional clamping is required; SMBJ16D-M3/H is optimal for DC-biased rails like 24 V power or microcontroller I/O. |
| SMCJ16A-M3/H | Same VWM and polarity, but larger SMC (DO-214AB) package offering 1500 W PPPM and lower RθJA (50 °C/W). | Suitable for higher-energy surge environments (e.g., outdoor equipment, factory mains interfaces) where 600 W is insufficient. | Choose SMCJ16A-M3/H when board space allows and surge threat level exceeds IEC 61000-4-5 Level 4; SMBJ16D-M3/H fits tighter layouts with adequate 600 W rating. |

FAQ
What is the maximum clamping voltage of SMBJ16D-M3/H at its rated peak pulse current?
The SMBJ16D-M3/H has a maximum clamping voltage (VC) of 25.6 V at its rated peak pulse current (IPPM) of 23.4 A, measured using the standardized 10/1000 μs double-exponential surge waveform. This value defines the highest voltage the protected circuit will experience during a worst-case transient event, making it critical for verifying compatibility with downstream IC voltage tolerances. The SMBJ16D-M3/H maintains this clamping performance across its qualified operating temperature range.
Is SMBJ16D-M3/H suitable for protecting 24 V DC power rails?
Yes, SMBJ16D-M3/H is specifically suited for 24 V DC rail protection: its 16 V stand-off voltage (VWM) provides sufficient margin below 24 V nominal, while its 18.1–19.4 V breakdown range ensures reliable triggering before damaging overvoltage occurs. The 25.6 V clamping voltage stays well within the absolute maximum ratings of most 3.3 V/5 V/12 V logic and interface ICs powered from that rail. SMBJ16D-M3/H is widely deployed in PLC I/O modules and industrial power supplies for this purpose.
Does SMBJ16D-M3/H have a bidirectional version, and how does it differ?
Yes, the bidirectional counterpart is SMBJ16A-M3/H, which uses the CD suffix convention and offers symmetrical clamping in both directions. Unlike SMBJ16D-M3/H - which conducts only in reverse bias and marks cathode with a band - SMBJ16A-M3/H has no polarity marking and clamps transients of either polarity at matched thresholds. Its VBR range is slightly wider (18.1–20.8 V), and it is selected for AC-coupled or floating lines such as RS-485, CAN, or audio paths where bipolar surges occur.
What is the thermal resistance and power derating behavior of SMBJ16D-M3/H?
SMBJ16D-M3/H has a typical junction-to-mount thermal resistance (RθJM) of 20 °C/W and a junction-to-ambient resistance (RθJA) of 100 °C/W on minimum recommended pad layout. Its steady-state power dissipation drops from 1.0 W at 25 °C ambient to zero at 150 °C junction temperature, following a linear derating curve. For surge events, peak power is limited to 600 W only for ≤50 ms pulses, with repetition constrained to 0.01% duty cycle - all defined in the Vishay datasheet 87606.
How does the M3/H suffix affect SMBJ16D-M3/H's compliance and packaging?
The "M3" suffix indicates halogen-free, RoHS-compliant, industrial-grade construction with matte tin-plated leads qualified to J-STD-002 and JESD 22-B102 solderability standards, plus JESD 201 Class 2 whisker resistance. The "H" denotes packaging in 7″ plastic tape-and-reel format with 750 units per reel - optimized for high-speed pick-and-place assembly. These markings confirm SMBJ16D-M3/H meets environmental, reliability, and manufacturing requirements for modern SMT production lines.
