Product details
Overview
SMBJ16D-M3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails 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 clamping voltage (VC) at 23.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBJ16D-M3/I datasheet, SMBJ16D-M3/I pinout, SMBJ16D-M3/I application, or SMBJ16D-M3/I equivalent, key selection criteria include clamping performance under surge conditions, low leakage (<0.5 μA at VWM), tight ±3.5% VBR tolerance, MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant industrial-grade construction.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its specified breakdown range. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients, while the 125 °C/W junction-to-ambient thermal resistance reflects performance on standard PCB pad layouts.
The device complies with ANSI/IEEE C62.35 for surge suppression and meets UL 497B recognition (QVGQ2) for protector classification. It is rated for -55 °C to +150 °C operating junction temperature and supports repetitive surge duty cycles up to 0.01% with 10/1000 μs waveform.
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% tolerance ensures predictable turn-on threshold |
| VC @ IPPM | 25.6 V at 23.4 A - Clamped voltage during 600 W 10/1000 μs surge, limiting stress on downstream ICs |

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/I | Bidirectional variant with same VWM (16 V), but symmetric clamping in both polarities; VBR = 18.1–19.4 V in either direction | Required where AC-coupled or floating signal lines need protection from both positive and negative transients | Select SMBJ16A-M3/I only if bidirectional clamping is explicitly needed; SMBJ16D-M3/I provides superior leakage and tighter unidirectional coordination |
| SMAJ16A-M3/8A | Lower power rating (400 W vs. 600 W); SMA package (smaller footprint, higher RθJA = 150 °C/W); same VWM/VBR range | Suitable for space-constrained consumer applications with lower surge exposure; not recommended for industrial 600 W compliance | Choose SMAJ16A-M3/8A only when board area is critical and surge threat level is below IEC 61000-4-5 Level 3; SMBJ16D-M3/I delivers higher robustness in shared PCB real estate |
Compared with SMBJ16A-M3/I and SMAJ16A-M3/8A, the SMBJ16D-M3/I offers optimal balance of 600 W surge capacity, industry-standard SMB footprint, and unidirectional precision for DC rail protection-making it preferred for industrial power supplies and automotive body electronics where asymmetric transient profiles dominate.

FAQ
What is the clamping voltage of SMBJ16D-M3/I at its rated peak pulse current?
The SMBJ16D-M3/I has a maximum clamping voltage (VC) of 25.6 V at 23.4 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated surge event, ensuring compatibility with 16 V-rated components and providing a safety margin below typical 30 V absolute maximum thresholds.
Is SMBJ16D-M3/I suitable for protecting 3.3 V logic interfaces?
No - SMBJ16D-M3/I is not appropriate for direct protection of 3.3 V logic interfaces because its 16 V stand-off voltage (VWM) and 25.6 V clamping voltage far exceed safe operating limits for such circuits. It is intended for 12–24 V DC rails; for 3.3 V lines, lower-voltage TVS devices like SMBJ3.3A or SMAJ3.3A are required.
Does SMBJ16D-M3/I have a bidirectional version?
Yes - the bidirectional counterpart is SMBJ16A-M3/I, which uses the same SMB package and shares identical VWM (16 V) and VBR (18.1–19.4 V) specifications but clamps symmetrically for both polarities. The "D" suffix denotes unidirectional polarity; "A" indicates bidirectional capability, with no cathode band marking.
What does the "-M3/I" suffix mean in SMBJ16D-M3/I?
The "-M3" suffix indicates halogen-free, RoHS-compliant, industrial-grade construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. The "/I" denotes packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units - optimized for high-volume SMT assembly lines.
Can SMBJ16D-M3/I be used in automotive under-hood applications?
Yes - SMBJ16D-M3/I is rated for junction temperatures up to +150 °C and qualified to MSL Level 1 (260 °C peak reflow), making it suitable for under-hood automotive applications such as engine control units and body control modules, provided PCB layout follows Vishay's recommended 5.0 mm × 5.0 mm copper pad for thermal management.
