Product details
Overview
SMBJ9.0D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 9.0 V stand-off voltage (VWM), 10.2–10.9 V breakdown voltage (VBR) at 1.0 mA, 15.1 V clamping voltage (VC) at 39.7 A peak pulse current, and 600 W peak pulse power rating for 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in industrial and telecom equipment.
For engineers reviewing the SMBJ9.0D-M3/H datasheet, SMBJ9.0D-M3/H pinout, SMBJ9.0D-M3/H application, or SMBJ9.0D-M3/H equivalent, key selection criteria include unidirectional polarity, ±3.5 % VBR tolerance, 0.5 μA max reverse leakage 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 clamping device in parallel with sensitive circuit nodes, triggering when transient voltage exceeds its breakdown threshold and diverting surge current away from downstream components. Its low incremental surge resistance and fast response time ensure effective suppression of sub-microsecond transients induced by inductive load switching or lightning surges.
The SMBJ9.0D-M3/H is rated for 600 W peak pulse power under 10/1000 μs waveform with 0.01 % duty cycle, derated above 25 °C ambient per thermal curves, and supports steady-state power dissipation up to 1.0 W at TA = 25 °C and 5.0 W at TM = 50 °C on infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 10.2 V / 10.9 V at 1.0 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 15.1 V at 39.7 A - clamping voltage defines worst-case overvoltage seen by protected IC during surge |
| PPPM | 600 W - peak pulse power handling for 10/1000 μs waveform, critical for IEC 61000-4-5 compliance margin |
| ID @ VWM | 0.5 μA max - ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max | +150 °C - junction temperature limit enabling reliable operation in high-ambient industrial environments |
| RθJA | 125 °C/W - thermal resistance to ambient on minimum recommended pad layout guides PCB copper area design |

IC Role / Device Role / Timing Role: Low-leakage (0.5 μA) TVS placed across sensor output terminals to shunt transients while preserving measurement accuracy. Use Value: Enables <0.01 % full-scale error contribution from leakage current, critical for 16-bit precision sensor systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A-M3/H | Same VWM (9.0 V), but tighter VBR tolerance (±2.5 %); otherwise identical ratings and package | Preferred where tighter clamping consistency is required across temperature and lifetime | Select SMBJ9.0A-M3/H only if design requires tighter than ±3.5 % VBR control; SMBJ9.0D-M3/H offers broader availability and cost advantage |
| P6SMB9.0A | Same SMB package and VWM, but lower PPPM (600 W vs. 600 W), higher VC (15.4 V), and ±5 % VBR tolerance | Acceptable for less demanding surge immunity requirements where 0.3 V higher clamping is tolerable | Choose P6SMB9.0A only if legacy qualification or dual-sourcing mandates ON Semiconductor compatibility; SMBJ9.0D-M3/H delivers superior clamping performance |
Compared with SMBJ9.0A-M3/H, the SMBJ9.0D-M3/H trades ±2.5 % VBR tolerance for wider manufacturing yield and lower cost, while versus P6SMB9.0A it provides tighter VBR control and lower clamping voltage - making SMBJ9.0D-M3/H optimal for new designs prioritizing consistent protection margin and supply chain flexibility.

FAQ
What is the maximum clamping voltage of SMBJ9.0D-M3/H at its rated peak pulse current?
The SMBJ9.0D-M3/H has a maximum clamping voltage (VC) of 15.1 V at its rated peak pulse current (IPPM) of 39.7 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ9.0D-M3/H maintains this clamping performance across its specified operating temperature range of -55 °C to +150 °C.
Is SMBJ9.0D-M3/H suitable for bidirectional transient protection?
No, SMBJ9.0D-M3/H is a unidirectional TVS diode, indicated by the "D" suffix and presence of a cathode band. It protects against positive transients on the anode side relative to cathode (ground). For bidirectional protection, Vishay offers the SMBJ9.0CD-M3/H variant with "CD" suffix and no polarity marking. Using SMBJ9.0D-M3/H in bidirectional applications risks failure during negative excursions beyond its reverse breakdown rating.
What does the "-M3/H" suffix indicate in SMBJ9.0D-M3/H?
The "-M3" suffix denotes halogen-free, RoHS-compliant construction meeting JESD 201 Class 2 whisker resistance, while "/H" specifies packaging in 7″ diameter plastic tape and reel with 750 units per reel. This ordering code ensures traceable industrial-grade material content and automated placement compatibility. The SMBJ9.0D-M3/H conforms to UL 497B recognition (file E136766) and meets MSL Level 1 per J-STD-020.
How does SMBJ9.0D-M3/H compare to SMAJ9.0A in terms of power handling?
SMBJ9.0D-M3/H delivers 600 W peak pulse power in the larger SMB (DO-214AA) package, whereas SMAJ9.0A is rated for 400 W in the smaller SMA (DO-214AC) body. The SMBJ9.0D-M3/H's 25 % higher PPPM enables more robust surge immunity in high-energy applications like industrial power supplies. Its RθJA of 125 °C/W also supports better thermal management than SMAJ9.0A's typical 150 °C/W on equivalent PCB layouts.
Can SMBJ9.0D-M3/H be used in automotive applications requiring AEC-Q200 qualification?
The SMBJ9.0D-M3/H is not AEC-Q200 qualified. While it meets industrial temperature range (-55 °C to +150 °C) and mechanical robustness standards, Vishay does not list this part in its AEC-Q200-certified portfolio. For automotive body electronics or infotainment systems requiring AEC-Q200, consider the AEC-Q200-qualified SMF9.0A or SMCJ9.0A families - the SMBJ9.0D-M3/H remains appropriate for non-safety-critical industrial and telecom applications.
