Product details
Overview
SMBJ100CD-M3/H from Vishay General Semiconductor is a bidirectional 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 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, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and telecom equipment.
For engineers reviewing the SMBJ100CD-M3/H datasheet, SMBJ100CD-M3/H pinout, SMBJ100CD-M3/H application, or SMBJ100CD-M3/H equivalent, key selection criteria include bidirectional polarity, ±3.5 % VBR tolerance, low leakage (<0.5 μA at VWM), MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction per JESD 201 Class 2 whisker test.
Technical Context
This TVS diode operates as a voltage-clamping protection device that responds within picoseconds to transient overvoltages induced by inductive switching or ESD events. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
The SMBJ100CD-M3/H uses an avalanche breakdown mechanism to divert surge current away from protected circuitry while maintaining low dynamic impedance. It is rated for repetitive 10/1000 μs surges at 0.01 % duty cycle and derates linearly above 25 °C ambient, with thermal resistance RθJA of 125 °C/W on minimum pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 113 V / 121 V at 1 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 159 V at 3.77 A - clamping voltage defines worst-case stress on downstream components during surge |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform, enabling robust protection against lightning-induced surges |
| ID @ VWM | <0.5 μA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ max | +150 °C - extended junction temperature rating supports operation in high-ambient industrial environments |
| Package | SMB (DO-214AA) - standardized surface-mount outline compatible with automated pick-and-place and reflow |
Pinout & Package
Two-terminal device in SMB (DO-214AA) package; no cathode band marking due to bidirectional polarity. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, with M3 suffix indicating halogen-free, RoHS-compliant, industrial-grade construction meeting JESD 201 Class 2 whisker resistance.

IC Role / Device Role / Timing Role: Bidirectional clamping device connected between signal line and return, guarding ADC inputs against wiring faults and ESD. Use Value: Preserves measurement accuracy by limiting fault voltage to 159 V while contributing <0.5 μA leakage that avoids offset error in precision current-to-voltage conversion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA-M3/5B | Same VWM/VBR/VC specs; differs only in tape-and-reel packaging (5B = 3200-unit reel vs. H = 750-unit reel) | No functional difference; identical electrical and thermal performance | Select SMBJ100CA-M3/5B for high-volume SMT production requiring larger reel quantities |
| P6SMB100CA | Same SMB package and bidirectional 100 V rating, but lower 600 W PPPM rating derated to 500 W per some revisions; VBR tolerance ±5 % | Marginally reduced clamping consistency and surge margin; not qualified to JESD 201 Class 2 whisker test | Use P6SMB100CA only where cost sensitivity outweighs long-term reliability in harsh thermal cycling environments |
Compared with SMBJ100CD-M3/H, SMBJ100CA-M3/5B offers identical protection performance in a different reel format, while P6SMB100CA trades tighter VBR tolerance and whisker resistance for lower unit cost - making SMBJ100CD-M3/H optimal for mission-critical industrial and telecom deployments requiring guaranteed parametric stability.

FAQ
What is the clamping voltage of SMBJ100CD-M3/H at its rated peak pulse current?
The SMBJ100CD-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 standard 10/1000 μs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated transient event and is confirmed in the Vishay datasheet Document Number 87606, page 2.
Is SMBJ100CD-M3/H unidirectional or bidirectional?
SMBJ100CD-M3/H is a bidirectional transient voltage suppressor, indicated by the "CD" suffix in its part number. Unlike unidirectional variants (e.g., SMBJ100D), it lacks a cathode band and provides symmetrical clamping in both polarities - essential for protecting AC-coupled lines, differential buses like CAN, or floating sensor inputs where voltage polarity reversal occurs.
Does SMBJ100CD-M3/H meet RoHS and halogen-free requirements?
Yes, SMBJ100CD-M3/H meets RoHS Directive 2011/65/EU and is halogen-free, as confirmed by the "M3" suffix in its ordering code. It complies with Vishay's material categorization standard (www.vishay.com/doc?99912) and passes JESD 201 Class 2 whisker testing - making it suitable for industrial and telecom applications requiring strict environmental compliance and long-term solder joint reliability.
What is the maximum operating junction temperature for SMBJ100CD-M3/H?
The maximum operating junction temperature (TJ max) for SMBJ100CD-M3/H is +150 °C, as specified in the Absolute Maximum Ratings table of the Vishay datasheet. This rating supports reliable operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations when mounted on appropriate copper pad areas per the recommended layout.
Can SMBJ100CD-M3/H be used in place of SMBJ100CA-M3/5B?
Yes, SMBJ100CD-M3/H can be used in place of SMBJ100CA-M3/5B for all electrical and thermal functions, as both share identical VWM (100 V), VBR (113–121 V), VC (159 V), and PPPM (600 W) specifications. The only differences are packaging format (H = 750-unit reel, 5B = 3200-unit reel) and minor branding - no PCB or schematic changes are needed when substituting SMBJ100CD-M3/H into designs originally specifying SMBJ100CA-M3/5B.
