Product details
Overview
SMBJ90CD-M3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 90 V standoff voltage (VWM), 102–109 V breakdown voltage (VBR), 144 V clamping voltage (VC) at 4.17 A peak pulse current, and 600 W peak pulse power rating for 10/1000 μs waveform-designed to protect power rails and signal lines in industrial sensor interfaces.
For engineers reviewing the SMBJ90CD-M3/I datasheet, SMBJ90CD-M3/I pinout, SMBJ90CD-M3/I application, or SMBJ90CD-M3/I equivalent, this page delivers verified electrical parameters, bidirectional polarity confirmation, thermal resistance (RθJA = 125 °C/W), MSL Level 1 compliance, and RoHS/halogen-free status per JESD201 Class 2 whisker test-key inputs for surge protection layout and reliability validation.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling clamp-on-both-sides transient suppression without polarity orientation constraints. Its 144 V clamping voltage at 4.17 A ensures predictable overvoltage limiting during ESD or inductive switching events, while low incremental surge resistance supports fast energy dissipation.
The device uses silicon avalanche junction technology with tight ±3.5 % VBR tolerance (102–109 V), rated for -55 °C to +150 °C junction temperature, and meets UL 497B recognition (QVGQ2) for telecom and industrial protector classification-validating its use in safety-critical surge paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V reverse stand-off voltage-defines maximum continuous operating voltage before conduction begins |
| VBR min/max | 102 V / 109 V at 1 mA test current-tight ±3.5 % tolerance enables precise overvoltage threshold setting |
| VC @ IPPM | 144 V clamping voltage at 4.17 A peak pulse-limits downstream voltage stress during 10/1000 μs transients |
| PPPM | 600 W peak pulse power-supports robust surge immunity per IEC 61000-4-5 Level 4 when mounted on recommended pad layout |
| ID @ VWM | 0.5 μA max reverse leakage-minimizes standby power loss in high-impedance monitoring circuits |
| RθJA | 125 °C/W junction-to-ambient thermal resistance-dictates derating above 25 °C ambient for sustained power handling |

Applications
| Industrial Sensor Signal Protection | DC Power Rail Surge Suppression |
|---|---|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors exposed to inductive switching noise in factory automation cabinets. IC Role / Device Role / Timing Role: Bidirectional TVS placed across signal line and ground to clamp both positive and negative transients before they reach ADC input or isolation amplifier. Use Value: 144 V clamping voltage prevents damage to 24 V-rated signal conditioning ICs during 1 kV/2 kV EFT bursts per IEC 61000-4-4. | Use Scenario: Safeguarding 24 V or 48 V DC input rails of programmable logic controllers (PLCs) against load dump and back-EMF from solenoid actuation. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing surge energy between rail and chassis ground during inductive turn-off events. Use Value: 600 W peak pulse rating sustains multiple 10/1000 μs surges up to 4.17 A without degradation-verified per JEDEC JESD22-A114. |
| Telecom Line Interface Protection | Automotive Body Control Module Inputs |
Use Scenario: Shielding RS-485 transceiver data lines in base station remote radio units subjected to lightning-induced common-mode surges on long cable runs. IC Role / Device Role / Timing Role: Bidirectional TVS placed differentially across A/B bus lines and common-mode to ground to suppress both differential and common-mode transients. Use Value: Symmetrical clamping ensures equal protection regardless of surge polarity-critical for full-duplex communication integrity under IEC 61000-4-5. | Use Scenario: Guarding wake-up inputs (e.g., LIN bus pins) of automotive body control modules against battery load dump and jump-start transients. IC Role / Device Role / Timing Role: TVS connected between LIN signal line and ground to limit voltage excursions beyond ISO 16750-2 pulse 5a/b limits. Use Value: 90 V VWM aligns with 12 V automotive nominal systems; 144 V VC stays below 160 V absolute maximum rating of typical LIN transceivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90CA-E3/52 (Vishay) | Same VWM/VBR/VC specs, but packaged in tape-and-reel with different reel size (500 pcs vs. 3200 pcs) and no M3 suffix-lacks JESD201 Class 2 whisker test compliance | Not qualified for high-reliability industrial deployments requiring whisker-resistant terminations | Select SMBJ90CD-M3/I when board-level reliability mandates whisker-tested matte tin plating per JESD201 Class 2 |
| P6SMB90CA (Littelfuse) | Identical VWM (90 V), VBR (102–109 V), VC (144 V), and PPPM (600 W); same SMB package-but rated only to TJ = 125 °C (vs. 150 °C) | Unsuitable for under-hood automotive or high-ambient industrial enclosures exceeding 125 °C junction temperature | Choose SMBJ90CD-M3/I for designs requiring extended thermal operation up to +150 °C junction temperature |
Compared with SMBJ90CA-E3/52 and P6SMB90CA, SMBJ90CD-M3/I uniquely combines M3-grade whisker resistance, UL 497B recognition, and 150 °C maximum junction rating-making it the preferred choice for long-lifecycle industrial and telecom infrastructure where field reliability and thermal headroom are critical.

FAQ
What is the polarity configuration of SMBJ90CD-M3/I?
SMBJ90CD-M3/I is a bidirectional TVS diode, meaning it functions identically in both forward and reverse directions-no cathode band marking is present, and either terminal may serve as anode or cathode depending on transient polarity. This eliminates orientation constraints during PCB assembly and ensures symmetrical clamping for AC-coupled or floating signal lines.
Does SMBJ90CD-M3/I meet UL safety certification requirements?
Yes, SMBJ90CD-M3/I is Underwriters Laboratory (UL) recognized under standard UL 497B (file E136766) for both unidirectional and bidirectional protectors. This certification validates its suitability in telecom and industrial applications where third-party safety approval is mandated for surge protection components.
What is the maximum clamping voltage of SMBJ90CD-M3/I under surge conditions?
The maximum clamping voltage (VC) of SMBJ90CD-M3/I is 144 V at a peak pulse current (IPPM) of 4.17 A with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is SMBJ90CD-M3/I compliant with lead-free and RoHS requirements?
Yes, SMBJ90CD-M3/I carries the M3 suffix indicating halogen-free, RoHS-compliant construction, matte tin-plated leads, and qualification to JESD201 Class 2 for whisker resistance-ensuring compatibility with modern lead-free reflow processes and long-term interconnect reliability in high-vibration environments.
What thermal derating applies to SMBJ90CD-M3/I above 25 °C ambient?
SMBJ90CD-M3/I exhibits linear thermal derating above 25 °C ambient: its power dissipation drops from 1.0 W at TA = 25 °C to zero at TA = 125 °C, based on RθJA = 125 °C/W. Derating curves per Figure 5 in document 87606 must be applied for steady-state power calculations in enclosed or high-ambient installations.
