Product details
Overview
SMBJ6.5D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 6.5 V stand-off voltage (VWM), 7.33–7.87 V breakdown voltage (VBR) at 10 mA, 11.0 V clamping voltage (VC) at 54.5 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform - used to protect MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the SMBJ6.5D-M3/H datasheet, SMBJ6.5D-M3/H pinout, SMBJ6.5D-M3/H application, or SMBJ6.5D-M3/H equivalent, key selection criteria include unidirectional polarity, ±3.5 % VBR tolerance, low 0.5 μA reverse leakage at VWM, M3 halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, activating when transient voltage exceeds its VBR threshold to divert surge current away from downstream components. Its low incremental surge resistance and fast response time ensure effective suppression of sub-microsecond transients induced by relay switching or motor commutation.
The SMBJ6.5D-M3/H is rated for 150 °C maximum junction temperature, features MSL Level 1 moisture sensitivity, and meets UL 497B recognition (QVGQ2) for telecom and industrial protector applications. Thermal resistance is 125 °C/W junction-to-ambient on minimum recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 7.33 V / 7.87 V at 10 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 11.0 V at 54.5 A - clamping voltage defines worst-case overvoltage seen by protected IC during 600 W surge |
| PPPM | 600 W - peak pulse power handling capability with 10/1000 μs waveform, 0.01 % duty cycle |
| ID @ VWM | 0.5 μA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 2.20 mm height and 5.59 mm length for high-density PCB layouts |
Pinout & Package
Two-terminal unidirectional TVS diode in SMB (DO-214AA) package; cathode denoted by band marking on body. Matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A-M3/H | Same VWM/VBR/VC specs but A-suffix denotes automotive-grade qualification (AEC-Q101) | Required for automotive ECUs; not necessary for industrial or consumer use | Select SMBJ6.5A-M3/H only if AEC-Q101 compliance is mandated |
| P6SMB6.5A | Identical electrical specs but different branding (Littelfuse); same SMB package and pinout | No functional difference; dual-sourcing option with alternate supply chain | Use P6SMB6.5A for second-source assurance without layout change |
Compared with SMBJ6.5D-M3/H, SMBJ6.5A-M3/H adds AEC-Q101 qualification at no electrical trade-off, while P6SMB6.5A provides identical performance with Littelfuse logistics - both retain the same 11.0 V clamping and 54.5 A surge rating for drop-in replacement where sourcing flexibility matters.

FAQ
What is the clamping voltage of SMBJ6.5D-M3/H at its rated peak pulse current?
The SMBJ6.5D-M3/H has a maximum clamping voltage (VC) of 11.0 V at 54.5 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated 600 W transient event. The SMBJ6.5D-M3/H maintains this clamping performance across its specified operating temperature range and is validated per ANSI/IEEE C62.35 surge test standards.
Is SMBJ6.5D-M3/H suitable for bidirectional transient protection?
No, SMBJ6.5D-M3/H is a unidirectional TVS diode, indicated by the "D" suffix (not "CD"). It protects against positive transients only - reverse voltage beyond VWM will conduct like a forward-biased diode. For bidirectional protection, select SMBJ6.5CD-M3/H, which has symmetrical breakdown in both directions and no cathode band marking. The SMBJ6.5D-M3/H must be oriented correctly on PCB with cathode toward the protected line.
What does the "M3/H" suffix mean in SMBJ6.5D-M3/H?
The "M3" suffix indicates halogen-free, RoHS-compliant, industrial-grade 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 configuration supports automated pick-and-place assembly and qualifies for extended storage under controlled humidity conditions. The SMBJ6.5D-M3/H is not rated for automotive AEC-Q101 unless the "A" suffix replaces "D".
How does SMBJ6.5D-M3/H compare to SMAJ6.5A in terms of power handling?
SMBJ6.5D-M3/H delivers 600 W peak pulse power, whereas SMAJ6.5A is rated for 400 W - a 50 % higher surge capacity. This difference arises from the larger SMB (DO-214AA) package of SMBJ6.5D-M3/H versus the smaller SMA (DO-214AC) of SMAJ6.5A, enabling greater thermal mass and lower dynamic resistance. The SMBJ6.5D-M3/H is preferred in high-energy industrial environments where repeated 600 W surges occur.
Can SMBJ6.5D-M3/H be used in place of SMBJ6.5A-M3/H?
SMBJ6.5D-M3/H and SMBJ6.5A-M3/H share identical electrical specifications (VWM = 6.5 V, VC = 11.0 V, PPPM = 600 W) and mechanical form factor, but differ in qualification: SMBJ6.5A-M3/H is AEC-Q101 qualified for automotive use, while SMBJ6.5D-M3/H is industrial-grade. Substituting SMBJ6.5D-M3/H into an automotive design voids AEC compliance; however, for non-automotive applications, SMBJ6.5D-M3/H is fully functionally equivalent and cost-optimized.
