Product details
Overview
SMBJ6.5AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 11.2 V maximum clamping voltage (VC) at 53.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBJ6.5AHM3/H datasheet, SMBJ6.5AHM3/H pinout, SMBJ6.5AHM3/H application, or SMBJ6.5AHM3/H equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, clamping performance under repetitive surges, and halogen-free RoHS-compliant sourcing details - all specific to the HM3 automotive-grade variant with tape-and-reel delivery (H code).
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable avalanche response. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) and 20 °C/W junction-to-lead (RθJL) support reliable operation up to 150 °C junction temperature under defined PCB pad layouts.
The SMBJ6.5AHM3/H meets J-STD-020 MSL Level 1 moisture sensitivity and withstands 260 °C lead-free reflow peak temperature. It is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and exhibits 0.061 %/°C temperature coefficient of VBR, enabling predictable voltage-clamp stability across automotive ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected line's nominal DC bias. |
| VBR @ IT = 10 mA | 7.22–7.98 V - Measured breakdown range defining onset of avalanche conduction; ensures reliable turn-on above system operating voltage. |
| VC @ IPPM = 53.6 A | 11.2 V - Clamped voltage during 600 W 10/1000 µs surge; determines maximum stress imposed on downstream ICs during transient events. |
| PPPM | 600 W - Peak pulse power handling capability; defines energy absorption capacity for standardized lightning/surge waveforms. |
| IPPM | 53.6 A - Peak surge current corresponding to VC; used with PCB trace impedance to estimate actual clamping margin. |
| TJ max. | 150 °C - Maximum allowable junction temperature; constrains sustained power dissipation and thermal design of heatsinking pads. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; optimized for automated placement and JEDEC-compliant reflow. |
Pinout & Package
Package: SMB (DO-214AA), unidirectional configuration with cathode band marking on one end. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker resistance Class 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest-potential node in unidirectional clamping; forms return path for surge current. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 5 V rail or sensor output); avalanche conduction initiates here during overvoltage. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5AHE3/H | Same electrical specs and SMB package, but RoHS-compliant commercial grade (E3) without halogen-free certification or AEC-Q101 qualification. | Lacks automotive qualification and halogen-free declaration; suitable for consumer/industrial designs where AEC-Q101 is not mandated. | Select SMBJ6.5AHE3/H for cost-sensitive non-automotive applications requiring identical clamping performance and tape-and-reel packaging. |
| SMAJ6.5A-HF | Lower 400 W PPPM, SMA (DO-214AC) package (smaller footprint, higher RθJA = 140 °C/W), same VWM/VC ratings. | Reduced surge energy handling and thermal margin; limited to lower-duty-cycle or space-constrained consumer PCBs. | Choose SMAJ6.5A-HF only when board area is critical and surge threat level is below IEC 61000-4-5 Level 3; not recommended for automotive or industrial mains-connected systems. |
Compared with SMBJ6.5AHE3/H, the SMBJ6.5AHM3/H adds halogen-free compliance and AEC-Q101 validation without altering clamping behavior - essential for Tier-1 automotive sourcing. Against SMAJ6.5A-HF, it delivers 50 % higher surge power and superior thermal management in the same layout family, justifying its use in mission-critical protection nodes.

FAQ
What is the clamping voltage of SMBJ6.5AHM3/H at its rated peak pulse current?
The SMBJ6.5AHM3/H has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current (IPPM) of 53.6 A using 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 SMBJ6.5AHM3/H maintains this clamping performance consistently across its qualified operating temperature range.
Is SMBJ6.5AHM3/H qualified for automotive applications?
Yes, SMBJ6.5AHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix - denoting halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes stress testing per AEC-Q101 Rev D, including HTGB, HTRB, and temperature cycling, making it suitable for under-hood and cabin electronics. The SMBJ6.5AHM3/H data sheet explicitly lists AEC-Q101 qualification in the Mechanical Data section.
What does the "H" in SMBJ6.5AHM3/H signify in the ordering code?
The final "H" in SMBJ6.5AHM3/H specifies the preferred package code for 7-inch diameter plastic tape-and-reel delivery, containing 750 units per reel. This matches Vishay's standard ordering convention where "H" denotes the 7″ reel option, distinct from "I" (13″ reel) or "52"/"5B" (alternate reel codes). The SMBJ6.5AHM3/H reel format ensures compatibility with high-speed SMT pick-and-place equipment.
How does SMBJ6.5AHM3/H differ from SMBJ6.5A-M3 in terms of compliance?
SMBJ6.5AHM3/H is identical in electrical and mechanical specifications to SMBJ6.5A-M3 but adds AEC-Q101 qualification and uses the "H" reel packaging code. The "HM3" suffix confirms halogen-free, RoHS-compliant construction with automotive qualification, whereas "M3" alone indicates halogen-free RoHS compliance without AEC-Q101 validation. Both share the same SMB package, VWM, and VC, but only SMBJ6.5AHM3/H meets automotive reliability standards.
Can SMBJ6.5AHM3/H be used in bidirectional configurations?
No, SMBJ6.5AHM3/H is strictly a unidirectional TVS diode, as confirmed by its part number suffix "A" and cathode-band marking. Bidirectional variants use the "CA" suffix (e.g., SMBJ6.5CA). Attempting to use SMBJ6.5AHM3/H for bidirectional protection would result in forward conduction and failure during negative transients. For symmetric surge suppression, select SMBJ6.5CA or equivalent bidirectional models instead of SMBJ6.5AHM3/H.
