Product details
Overview
SMBJ9.0CD-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 signal and power lines. It features a 9.0 V stand-off voltage (VWM), 10.2–10.9 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤15.1 V at 5.0 A peak surge current - protecting sensitive MOSFETs and sensor interfaces in industrial control systems.
For engineers reviewing the SMBJ9.0CD-M3/H datasheet, SMBJ9.0CD-M3/H pinout, SMBJ9.0CD-M3/H application, or SMBJ9.0CD-M3/H equivalent, key selection criteria include bidirectional clamping capability, ±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 bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its silicon avalanche structure enables sub-nanosecond response to ESD and lightning-induced surges, while low incremental surge resistance ensures stable clamping under repetitive transients.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient, delivering 1.0 W steady-state power dissipation at TA = 25 °C and 5.0 W at TM = 50 °C when mounted on recommended copper pad layout. Thermal resistance junction-to-ambient is 125 °C/W (typ.) on minimum pad, enabling reliable operation in compact industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 9.0 V - maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 10.2–10.9 V at 1 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC (Clamping Voltage) | ≤15.1 V at IPPM = 5.0 A - limits downstream voltage stress during 10/1000 μs surge events |
| PPPM (Peak Pulse Power) | 600 W - sustains high-energy transients without failure under standard 10/1000 μs waveform |
| ID (Reverse Leakage) | ≤0.5 μA at VWM - minimizes standby power loss and avoids false triggering in high-impedance circuits |

IC Role / Device Role / Timing Role: Localized TVS at motor connector interface, clamping transients before they couple into microcontroller GPIO or comparator inputs. Use Value: Eliminates firmware resets caused by voltage spikes exceeding MCU input absolute maximum ratings (e.g., STM32G0 series). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ9.0CA | Same SMB package, 9.0 V VWM, but ±5 % VBR tolerance (vs. ±3.5 %); 14.4 V VC at 5.0 A | Higher clamping voltage reduces protection margin for low-voltage logic interfaces | Acceptable where tighter VBR tolerance is not required and layout allows higher VC headroom |
| ON Semiconductor SMCJ9.0CA | SMC (DO-214AB) package - larger footprint and higher thermal mass; 15.0 V VC at 5.0 A | Requires PCB redesign due to different pad layout and mounting area; better for higher average power dissipation | Preferred when thermal performance >1.0 W at TA = 25 °C is needed and board space permits larger package |
Compared with SMBJ9.0CD-M3/H, SMAJ9.0CA offers lower cost but looser VBR tolerance and higher clamping voltage, while SMCJ9.0CA delivers superior thermal handling in larger form factor - choice depends on layout constraints, precision clamping needs, and thermal budget.

FAQ
What is the polarity configuration of SMBJ9.0CD-M3/H?
SMBJ9.0CD-M3/H is a bidirectional TVS diode with no polarity marking - both terminals are functionally identical and provide symmetrical clamping in either direction. This eliminates orientation errors during automated placement and simplifies design for AC or floating signal paths. The "CD" suffix explicitly denotes bidirectional functionality per Vishay's naming convention.
Does SMBJ9.0CD-M3/H meet automotive AEC-Q200 requirements?
No, SMBJ9.0CD-M3/H is not AEC-Q200 qualified. It is rated for industrial temperature range (−55 °C to +150 °C) and meets JESD 201 Class 2 whisker testing, but lacks the extended reliability testing (e.g., temperature cycling, vibration, board flex) required for automotive qualification. For AEC-Q200 applications, consider Vishay's Automotive-grade SMBJ series with "-HE3" or "-HM3" suffixes.
What is the maximum surge current SMBJ9.0CD-M3/H can handle at 85 °C ambient?
At TA = 85 °C, SMBJ9.0CD-M3/H derates to approximately 70 % of its 25 °C IPPM rating. From the datasheet, its IPPM is 5.0 A at 25 °C (10/1000 μs), so at 85 °C it supports ~3.5 A peak surge current. This derating follows the curve in Figure 2 and assumes mounting on the minimum recommended pad layout per JEDEC MO-136.
Can SMBJ9.0CD-M3/H be used in parallel for higher power handling?
No - paralleling SMBJ9.0CD-M3/H devices is not recommended due to mismatch in VBR and dynamic impedance, which causes uneven current sharing and potential thermal runaway. For higher power, select a single higher-rated device (e.g., SMCJ9.0CA) or use a TVS array optimized for balanced multi-channel clamping. Always verify layout symmetry and trace inductance if forced to parallel.
What does the "-M3/H" suffix indicate in SMBJ9.0CD-M3/H?
The "-M3" suffix denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. The "/H" indicates packaging in 7″ diameter plastic tape and reel with 750 units per reel - standard for high-volume SMT assembly. Both elements are defined in Vishay's ordering information table on page 3 of document 87606.
