Product details
Overview
SMBJ100D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 100 V stand-off voltage (VWM), 113–121 V breakdown voltage (VBR) at 1 mA, 159 V maximum clamping voltage (VC) at 3.77 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBJ100D-M3/H datasheet, SMBJ100D-M3/H pinout, SMBJ100D-M3/H application, or SMBJ100D-M3/H equivalent, key selection criteria include its ±3.5 % VBR tolerance, 0.5 μA max reverse leakage at VWM, M3-grade halogen-free RoHS-compliant construction, and suitability for industrial power supply input protection, automotive body electronics, and telecom interface surge suppression.
Technical Context
This unidirectional TVS diode operates as a clamping device that remains high-impedance below VWM (100 V) and rapidly transitions to low-impedance conduction above VBR (113–121 V), limiting transient voltages to ≤159 V at 3.77 A. Its junction-to-ambient thermal resistance is 125 °C/W on minimum pad layout, enabling reliable operation up to 150 °C junction temperature.
The SMBJ100D-M3/H meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. It delivers 600 W peak pulse power at 0.01 % duty cycle and exhibits fast response time (<1 ns) to ESD and lightning-induced transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - Maximum continuous reverse operating voltage before significant leakage begins; defines safe DC rail operating margin. |
| VBR (Breakdown Voltage) | 113–121 V at 1 mA - Tight ±3.5 % tolerance ensures predictable turn-on across production lots and temperature. |
| VC (Clamping Voltage) | 159 V at IPPM = 3.77 A - Limits transient voltage seen by downstream ICs during 10/1000 μs surges. |
| PPPM (Peak Pulse Power) | 600 W - Sustains standardized lightning/surge events without failure under specified waveform and derating. |
| ID (Reverse Leakage) | ≤0.5 μA at VWM - Minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated assembly; 5.59 mm × 4.06 mm outline, MSL Level 1. |
| TJ max | 150 °C - Enables use in under-hood automotive, industrial motor drives, and enclosed power supplies. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; cathode indicated by band at one end; matte tin-plated leads compliant with J-STD-002 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; forms forward-biased path during positive transients on cathode side. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., +12 V rail); conducts surge current to ground when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Ensures consistent clamping threshold across batches and temperatures-critical for tight-margin power rail protection. |
| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surge (4 kV line-earth) without degradation when properly mounted. |
| Low 0.5 μA leakage at 100 V | Preserves battery life in always-on systems and avoids loading sensitive analog sensor references. |
| M3 suffix compliance | Halogen-free, RoHS-compliant, and passes JESD201 Class 2 whisker test-required for industrial and automotive deployments. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without preconditioning-reduces manufacturing complexity and cost. |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-M3/H | Bidirectional variant; symmetric VBR (113–121 V) and VC (159 V) in both polarities; same PPPM and package. | Required where AC-coupled lines or bidirectional signals (e.g., RS-485, CAN) need protection against ± transients. | Select SMBJ100A-M3/H only if polarity-agnostic clamping is needed; SMBJ100D-M3/H is preferred for DC rails with defined ground reference. |
| SMCJ100A | Larger SMC (DO-214AB) package; higher 1500 W PPPM; same VWM/VBR/VC specs but 50 % larger footprint and 2× thermal mass. | Suitable for higher-energy surge environments (e.g., outdoor telecom cabinets) where PCB space permits larger devices. | Choose SMCJ100A only when 600 W is insufficient and board layout allows SMC footprint; SMBJ100D-M3/H offers optimal density for space-constrained designs. |
Compared with SMBJ100A-M3/H and SMCJ100A, the SMBJ100D-M3/H provides unidirectional clamping in the smallest standard surface-mount TVS package with verified 600 W capability-making it ideal for compact, cost-sensitive DC power rail protection where polarity is fixed and energy levels are moderate.

FAQ
What is the clamping voltage of SMBJ100D-M3/H at its rated peak pulse current?
The SMBJ100D-M3/H has a maximum clamping voltage (VC) of 159 V at its rated peak pulse current (IPPM) of 3.77 A, measured using the standardized 10/1000 μs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is guaranteed across the full operating temperature range.
Is SMBJ100D-M3/H suitable for automotive applications requiring AEC-Q200 qualification?
The SMBJ100D-M3/H is not AEC-Q200 qualified. While it meets UL 497B recognition and JESD201 Class 2 whisker resistance, Vishay does not list this specific variant under its AEC-Q200-certified TVS portfolio. For automotive-grade designs, engineers should verify qualification status directly with Vishay or select explicitly AEC-Q200–rated alternatives such as the Automotive SMBJ series (e.g., SMBJ100DHE3_A/H).
How does the M3 suffix affect the SMBJ100D-M3/H construction and compliance?
The M3 suffix on SMBJ100D-M3/H indicates halogen-free molding compound, RoHS compliance per Directive 2011/65/EU, industrial-grade reliability, and passivation meeting JESD201 Class 2 whisker resistance. It also specifies matte tin-plated terminals solderable per J-STD-002 and JESD22-B102, ensuring compatibility with lead-free reflow processes and long-term interconnect integrity.
Can SMBJ100D-M3/H be used in bidirectional signal line protection?
No-SMBJ100D-M3/H is a unidirectional TVS diode and must not be used on AC-coupled or bidirectional signal lines without external polarity conditioning. For such applications, the bidirectional variant SMBJ100A-M3/H is required, as it provides symmetrical clamping in both directions and lacks a cathode band marking.
What is the thermal resistance of SMBJ100D-M3/H when mounted on the minimum recommended pad layout?
When mounted on the minimum recommended copper pad layout (per Vishay document 87606), the SMBJ100D-M3/H exhibits a typical junction-to-ambient thermal resistance (RθJA) of 125 °C/W. This value governs steady-state power dissipation limits and must be applied in thermal derating calculations for continuous operation above 25 °C ambient.
